Reasons to Be Optimistic About the Future of the Environment (Part 1)

Securing natural capital and expanding equity to rescale civilization, Nature. / Paul R. Ehrlich, Peter M. Kareiva & Gretchen C. Daily

“It’s easy to be cynical or pessimistic” about the the state of the global environment, said David J. Skorton, secretary of the Smithsonian, at the opening of the Earth Optimism Summit in Washington, D.C. “We’re not blind to the realities, but if organizations and individuals work together, obstacles can be overcome.” Over three days, an audience of 1,400 heard one inspiring environmental success story after another. While no one forgot that climate change, biodiversity loss, and ecosystem degradation have created a global environmental emergency, there was a concerted effort to change the narrative — from one of relentless anger and despair to one of progress and a cautious optimism about the future. The goal was to highlight was is working today and figure out the ways to replicate and scale up successes.

Highlighted are a few of the success stories heard at the summit:

China Is Valuing Its Ecosystem Services: Gretchen Daly, professor of environmental science at Stanford University and founder of the Natural Capital Project, said more cities and countries are starting to put financial value on the many ecosystem services nature provides. Some success stories: New York realized that investing in the ecological functions of the watershed surrounding New York City was cheaper than building a massive filtration plant. Costa Rica has initiated a payment system for conserving nature.

And China has undertaken a massive planning effort to identify and value its critical ecological assets in an effort to become the “ecological civilization of the 21st century.” Some 4,000 officials in 31 provinces have been trained with Daly’s InVest software, which has helped Chinese policymakers identify “priority zones for carbon absorption, biodiversity, flood control, sandstorm control, and water purification.” Today, some 200 million Chinese are now getting paid to restore natural capital. Hainan has become the first “eco-province.” Daly said some 50 countries and cities are using the Natural Capital Project’s ecosystem service management system.

Truly inspiring, but it only happened after “China kissed disaster,” getting close to total environmental collapse. And China has decades of work ahead before its environment can be deemed healthy. Let’s hope the rest of the planet doesn’t have to get to the brink of catastrophe before it values increasingly-scarce resources.

In the U.S, Renewable Energy Is Where the Growth Is: In the U.S., all new power generation last year was renewable. Wind and solar power are the now the cheapest energy options, even when you remove the government subsidies. “This has been a huge change in the past decade,” said David Crane, Pegasus Capital Advisers. The model of financing solar panels in the U.S., which basically involving leasing someone’s roof space in return for giving them a discount on their home energy bills, made the solar revolution possible. That model has mobilized $1 trillion in capital and generated 250,000 megawatts of energy, explained Jigar Shah, with Generate Capital and SunEdison.

Renewable energy is no longer just a favorite cause of green Democrats either. Dale Ross, the mayor of deep-red Georgetown, Texas, a growing city of about 50,000, explained how he made a long-term agreement with wind and solar companies to power his city’s growth. Ross believes the U.S. will have 80 percent of its energy generated by wind and solar by 2025 if states are allowed to sell more power across borders. But Crane was less optimistic, pointing out that only 1.5 million homes now have solar panels, whereas there should be 50-55 million homes. “The power industry is a monopoly fighting rooftop solar. People need to stand up and pressure companies and regulators.”

On the positive side: GM, a fairly traditional company, just announced it will be 100 percent powered by renewable energy by 2040. And Walmart aims for 50 percent renewable energy sources by 2025. Architect William McDonough believes these companies will help “wage peace through commerce.” The leaders of the firms decided to “do the right thing and set positive goals.” These goals would have seemed impossible a decade ago.

Food Waste Is Now on Our Radar: There is a growing momentum across the developed world to end the egregious waste from the industrial agriculture and food retail industries. Food production is by far the biggest environmental impact humans have on the Earth, with agriculture covering a third of the surface. With the global population expected to hit 9-10 billion by 2050, many argue that food production will need to increase 50-70 percent. But Tristram Stuart, founder of Feedback and Toast Ale, argues that we actually already grow enough food to feed 12 billion people. Food overproduction is really the issue. As a result, we are creating not only huge amounts of waste but also producing obese populations. Globally, some one-third of food is wasted. In the U.S. and Europe, people are eating 1.5 to 2 times what they need.

Stuart said there are positive trends though, because “governments are starting to act and create measurable change.” In the UK, food waste has been reduced 27 percent since 2007. Taking on some of the “blatantly stupid waste of resources” perpetuated through the supply chains of supermarkets, his organization has used campaigns to show how waste can be reduced. For example, he convinced some UK supermarket chains to stop selling cut green beans, imported from Kenya, in favor of full beans that will not only stay fresh longer but reduce the amount of bean wasted in the process. His other company, Toast Ale, uses left-over ends of bread to craft beer. “You can get wasted on waste.”

Communities Are Organizing to Save Coastal Ecosystems: Ayana Johnson, founder of Ocean Collectiv, said there is now a greater understanding of coastal ecosystems and how they sequester far more carbon than terrestrial forests. As such, more coastal communities are making it much harder for corporations to privatize or over-develop coasts. There is a new awareness of the importance of preserving and restoring mangroves, even though some efforts to actually restore mangroves have not succeeded. Furthermore, “oyster restoration is gaining steam,” as communities realize they play an important role in buffering wave forces and filtering water.

In the Caribbean, where Johnson focuses her coastal community development work, there is a growing awareness that conserving ocean resources is a “social justice issue.” When marine reserves are established, “fish populations bounce back.” On the negative side, only 2-3 percent of the ocean is now protected, and scientists think it needs to be around 30 percent.

Not to sugarcoat: the future challenges facing our coastal communities are daunting. With warming waters, many fisheries are expected to migrate towards the poles, threatening millions of livelihoods. It’s not clear what shifting fisheries mean for the “half of the world who depend on seafood for their protein.”

Cities Are Rebuilding Connections to Nature: The old model in which cities were totally cut off from their waterfronts — either by highways or industrial facilities — seems to be ending in the developed world at least. Damon Rich, head of Hector Urban Design, walked us through one prime example of how communities are reconnecting to their waterfront in Newark, New Jersey, which transformed some of the edges of the Passaic River from “toxic nastiness” into the site of the 20-acre, $35 million Newark Riverfront Park that uses a “symbolic system” of bright orange to “reflect this is an anti-racist space.” To accomplish something like this, Rich said you need to “bring together the conservation, organizing, and design communities together and invite them to the same party.”

And then there are individuals who aren’t waiting around for the government to do something, but are starting their own new companies, schools, and movements. David Auerbach launched a company in the Mukuru slum of Kenya called Sanergy, which offers more sanitary restrooms than the standard pit latrine through a novel franchising model and significantly reduces urban water pollution. Users pay a small fee to the Sanergy restroom franchisee to use the restroom. Franchisees then safely collect the waste, which Sanergy picks up and turns into safe, organic fertilizer. Sanergy offers a promising solution to a “crappy problem”: 1 billion live in urban slums and 2 billion will by 2030. 4 billion live in communities where “waste is never treated.” There are 1 million deaths caused by poor sanitation each year.

At the age of 27, Murray Fisher started the public New York Harbor School, which teaches students in New York City maritime trades. Years later, the school moved to a new campus on Governor’s Island and now has 475 high school students, where they can receive credentials in aquaculture, vessel operations, marine biology, and more. After starting a new foundation, Fisher began the Billion Oyster Project, which aims to bring back that many oysters to New York City’s waters. The school engages the students in measuring the oysters the 20 million oysters they’ve planted, welding the reefs, and monitoring water quality. His goal is to “insert the local ecosystem back into the educational system” and eventually export his novel environmental education curricula to other communities who have eager students and significant unmet conservation and restoration needs. “Why can’t young people work on restoring ecosystems in school?”

And, lastly, Afroz Shah, a lawyer who lives in Mumbai, India, and was one of the most inspiring speakers at the summit, explained how he went from picking up trash by himself on the beloved beach where he used to play as a child to leading a movement of thousands who are cleaning up miles of urban Indian beaches. The United Nations Environment Program (UNEP) calls Shah’s effort the “world’s biggest beach clean-up,” with more than five million pieces of trash, mostly plastic bags, picked up.

He wants everyone to ask themselves: “What are you doing to rectify things?” You can “complain on social media or sign a petition and wait for someone else to do something,” or get out there yourself and do something to make things better. “We have a fundamental duty to our oceans.”

And Some Species Have Even Found Opportunities in Suburbs and Cities: Animals are also seizing space in our cities, without waiting for an invitation. Roland Kays, North Carolina Museum of Natural Sciences, explained how predatory fishers, which are like large weasels, are making a comeback in the suburbs of Albany, after being brought to the brink of extinction. Coyotes, which are hunted in rural areas, have discovered they are safer in suburbs and cities where residents are not allowed to fire a gun or run traps. Coyotes are now killing pets — “they really don’t like chihuahuas” — but they are helping to limit some pests, like geese. Wolves are now found in the Great Lakes region, mountain lions in Colorado and California, and leopards in urban India. “They are adapting to survive. If we give species a chance, they can survive.”

Reasons to Be Optimistic About the Future of the Environment (Part 2)

“It’s easy to be cynical or pessimistic” about the the state of the global environment, said David J. Skorton, secretary of the Smithsonian, at the opening of the Earth Optimism Summit in Washington, D.C. “We’re not blind to the realities, but if organizations and individuals work together, obstacles can be overcome.” Over three days, an audience of 1,400 heard one inspiring environmental success story after another. While no one forgot that climate change, biodiversity loss, and ecosystem degradation have created a global environmental emergency, there was a concerted effort to change the narrative — from one of relentless anger and to one of progress and a cautious optimism about the future. The goal was to highlight was is working today and figure out the ways to replicate and scale up successes.

Highlighted are a few more of the success stories heard at the summit (see part 1 for the first set):

Nature Is Being Preemptively Preserved: National Geographic Explorer Enric Sala, founder of Pristine Seas, stated that marine preserves where no fishing is allowed have five times the amount of biomass as unprotected parts of the ocean. These marine reserves are like “savings accounts that everyone can enjoy.” His goal is to preemptively turn the few remaining wild areas in the world’s oceans into reserves before exploitation can happen. In marine reserves, eco-tourism increases, creating lots of high-paying local jobs. In the Great Barrier Reef, off Australia’s eastern coast, “tourism revenue is 40 times that from fishing.” Today, 3.5 percent of our oceans are protected, but less than 2 percent fully-protected. The United Nation’s goal is 10 percent by 2020, and marine biologists say 30 percent by 2030 is really what’s needed.

On land, reserves are equally as critical to maintaining terrestrial biodiversity. Sean Gerrity, former president of the American Prairie Reserve, explained his organization’s efforts to create the largest nature reserve in America, some 3.5 million acres of prairie in an east-west swath of land 250 miles wide in northeast Montana. When they have finally purchased all the land they need, the reserve will be one million acres larger than Yellowstone National Park. The reserve, which will eventually be larger than the state of Connecticut, will have no fences. Cattle ranches at the edges will be tapped to maintain biodiversity by becoming “Wild Sky certified.” Like the Sustainable SITES Initiative™, Wild Sky requires strict adherence to a set of biodiversity protocols. When cattle ranchers spy rare species on camera traps on their properties, they receive “hundreds of dollars in return.” Gerrity thinks conservation must include a profit motive for the approach to work long-term. “Why can’t we have for-profit nature reserves? We can make money, bring jobs back, and protect wildlife.”

Madagascar, the 10th poorest nation on Earth, has cut down about 90 percent of its forests, which means some 94 percent of lemurs — who are only found on the island — are now endangered. While there are immense challenges, Stony Brook professor and MacArthur fellow Patricia Wright, professed herself to be an optimist. Working in Madagascar since the 1980s, she has seen the country create 18 national parks and a national park service that guards these lovable creatures from logging. She was the driving force behind the creation of the 105,000-acre Ramonafana National Park, a World Heritage Site in the southeastern part of the country, which now attracts 30,000 eco-tourists a year and has saved multiple rare lemur species from extinction.

People Are Making Room for Nature to Travel:  Transportation infrastructure, deforestation, fuel and mineral extraction, and development makes life difficult for many species. But using an ecological approach rooted in science, people can reduce or even reverse the negative impacts and give species a chance to survive and even flourish.

Joel Berger, Wildlife Conservation Society (WSC), described how WSC has helped create room for the Pronghorn, which migrates nearly 200 miles from the Grand Teton National Park in northwest Wyoming to the Green River Valley in southwest Wyoming and back again, year after year. Working with county commissioners, chambers of commerce, local non-profits, and newspapers, WSC helped carve out a permanent, protected path for this antelope-like mammal, which is actually a relative of the giraffe and okapi. In 2008, the path became “the first federally-protected wildlife corridor, and a bright spot” in conservation.

In Peru, exploratory oil pipelines are spreading through the Amazon rainforest. When paths are cut through the rainforest for trucks and pipelines, monkeys and other arboreal mammals find their pathways cut off, explained Tremaine Gregory, a scientist with the Smithsonian. Crossing on the ground is very dangerous, as they could more easily become the prey of jaguar. She wondered if companies left some tree crossings to connect the canopy on either side of the disturbances would be used by the monkeys? Analyzing camera traps set up on 13 canopy bridges she found that 25 species of arboreal mammals used the bridges, while just 6 would leave the trees and cross the ground. Out of 3,160 crossings by more than 150 distinct animals, just 16 were on the ground. Gregory is now in discussions with the Peruvian government and extraction companies about working canopy bridges into the regulations. “They are interested in the results; I’m optimistic.”

Forests Are Being Designed for Productivity:
In Madagascar, Wright has also focused her efforts on reforesting agricultural wastelands. “When a forest is regrown, the animals come back. We didn’t know that 25 years ago.” While there can be challenges in replanting with native plant seedlings on a massive scale, the secret was they only planted seeds “pooped out by lemurs.” Wastelands can be returned to forests. Under their canopies, high-value crops can be grown, such as vanilla, cinnamon, chocolate. “Making these forests productive again triples their value.”

Peter Marra, a scientist with the Smithsonian National Zoo, came up with a vision for how selective agroforesty can help save the world’s remaining forests. The demand for coffee is expected to grow by 25 percent by 2020 due to increasing demand from China and Latin America. If demand is met with more of the same — monocultural plantations, which require lots of water and chemicals — many forests will go under the bulldozer. Today, coffee is the second most-traded commodity in the world, after oil. The economic players involved earn $173 billion a year and take up 10.5 million acres of land. Each year, some 900 billion cups are consumed worldwide. If this morning essential is grown in the rich soils of forests, it can be less destructive and even be organic.

And Jefferson Hall, with the Smithsonian Tropical Research Institute’s Agua Salud project in Panama, told the story of how Panamanian policymakers realized the forested park around the Panama Canal is critical to controlling flooding during storms. A national plan to reforest one million acres of degraded forest land around the canal led to a new strategy to reintroduce native hardwood species, like the rare Cocobolo, which could then be harvested in a sustainable manner. A plus: Cocobolo, which sells for $10,000 per cubic meter, grows well in the acidic soils.

The Best Communicators Are Creating “Conservation Pride”: Instead of creating more and more refined “obituaries” for the planet’s species and ecosystems, more scientists realize they must tell more positive stories to motivate action. This is because “one-fourth to one-third of all children today think the world will come to an end before they die,” said Nancy Knowlton, a scientist at the Smithsonian, and one of the co-chairs of the summit. Brett Jenks, the CEO of Rare, said more conservationists are using marketing and human behavior change best practices to create a more conservationist ethic among the general public.

He pointed to Paul Butler, who created a movement in St. Lucia in the 1970s to save the near-extinct St. Lucia parrot, which featured a catchy song and a mascot dressed as “Jacquot,” which is the local name for the parrot. Scientists thought Butler would have no chance to save the parrot from extinction, but today there are more than 500 in the wild. Jenks said there are now some 350 conservation pride campaigns worldwide in 50 countries.

These behavior change campaigns “make behaviors observable, establish a conservation norm, make the norm clear to all, and make behavior explicit.” The idea is to change the focus of conservationists too: “they must focus on people and become human behavior change agents.” And Randy Olson, author of Houston, We Have a Narrative: Why Science Needs a Story, further emphasized that conservationists can only inspire positive action if they create a narrative that grabs the public. Given there are so many competing narratives, “if you don’t tell your story, someone else will.”

And We’ve Learned Everyone Can Make an Important Contribution: Whether at home or school, everyone can take action to improve the environment. Where the West and Rhode rivers meet in an estuary on the west coast of the Chesapeake Bay in Maryland, Riverkeeper Jeff Holland is convincing homeowners to play a role in cleaning up the Chesapeake Bay. Homeowners with docks within designated oyster sanctuaries are growing baby oysters or providing space for new reefs. “About 1,500 people are growing 3-4 cages, so it’s not a huge boost but it helps. Things are trending in the right direction.” Year and year, as each oyster filters a bathtub worth of water each day, the water gets clearer.

And across the Bay on the eastern shore, consultant Joanna Ogburn is linking up private homeowners for “large-scale landscape results” to tackle water quality problem areas in the Choptank and Nanticoke watersheds. Whether the homeowners she works with have an environmental ethic or not, she finds a way to motivate them to preserve parts of their estates through conservation easements. For some, it’s just about “keeping the rural character” and preventing out-of-town buyers from coming in and overdeveloping. For some, it’s about creating and connecting wildlife habitats.

Anyone with some outdoor space can boost local biodiversity. Phyllis Stiles, founder of Bee City USA and a self-proclaimed “buzzaholic,” is one of the leaders in the movement to fight colony collapse disorder among honeybees. But beyond honeybees, she said some 40 percent of all pollinator species — including numerous species of beetles, flies, native bees, butterflies, hummingbirds, moths, and bats — are at risk. Some 90 percent of wild plant species and 52 percent of our produce, covering approximately one-third of our food, depend on them. “It’s easy to point fingers at the big companies, but you can do something about it: plant natives, use less pesticides, remove exotic and invasive plants, and support local native plant nurseries.” Stiles now has 44 cities and 24 academic campuses on board to help pollinators.

And University of Delaware professor Doug Tallamy, well-known for his book Bringing Nature Home: How You Can Sustain Wildlife with Native Plants, re-iterated the importance of getting rid of lawn and exotic plants in favor of native trees and plants that play important roles in sustaining ecosystems. “Use plants that are pretty and support life. Conservation can the goal of our landscapes.” Native plants are the base of the food chain. Without them, there are no insects, which means no birds, bats, frogs, lizards, rodents, or mammals. But instead of trying to create change with “sticks” — through taxing lawns, which happens in dry lands out West — Tallamy wants to see local governments offer “carrots”: tax breaks if endangered species are found on your property.

Finally, an inspiring D.C. high school student Teddy Ammon, who found a grant to build indoor hydroponic farms in his school, cautioned that even with all the positive action and optimism, we shouldn’t be complacent for a moment or expect the next generation to improve on our efforts. “There are some 40-42 million 10-19 year olds. Some 46 percent of them don’t believe in climate change. And 57 percent aren’t concerned about it.” That’s a wake-up call to re-double our efforts.

Cities and Biodiversity Hotspots on Collision Course

Nearly 400 cities around the world are currently on a crash course with irreplaceable ecosystems, according to new research from Richard Weller, ASLA, professor and chair of the landscape architecture department at the University of Pennsylvania School of Design, and researchers Claire Hoch and Chieh Huang. Weller shared his findings at the launch for the Atlas for the End of World, which maps these biologically-rich areas and the threats they face.

Agriculture and urbanization, fueled by population increase, pose the greatest threats to these ecosystems. Weller’s team discovered the coming conflict zones by overlaying cities’ 2030 growth projections with maps of threatened species’ habitats.

Some 142 nations preside over biological hotspots. Under the United Nations Convention on Biological Diversity, a multilateral treaty that sets guidelines for protecting biological assets, each signatory nation must set forth a strategy for protecting its biologically-rich areas. Using the Atlas, a country’s officials can determine where they should focus their conservation efforts.

Global conservation efforts have been underway for some time. Policies have been enacted to protect certain species and rehabilitate or fence off biologically-rich habitat. One of the Atlas’ maps visualizes all large-scale restoration projects, both planned and underway, globally. These efforts are “historically unprecedented and mark an evolutionary paradigm shift,” Weller said.

But, unfortunately, these conservation efforts are also fragmented and diminished in impact, as most occur outside of the hotspots. Weller drove this point home with an image of what he termed a “global archipelago,” the Earth’s landmass minus its unprotected areas. The result of this subtraction is a system of small, isolated patches of conserved land.

For conservation to have a meaningful impact, it must protect biologically-rich areas, and these areas must connect with one another. A new era of large-scale landscape planning is needed.

Complicating the issue, Weller acknowledged, is the fact that many hotspots occur within countries struggling with poverty and corruption. The man who logs illegally for lack of other work won’t abide by policies that favor habitat over his family.

At the launch, Eugenie Birch, professor of urban research at the University of Pennsylvania School of Design, suggested the protection of hotspots was tied up not just with food production and development, but larger themes of inequality and conflict. Solving conflicts would help to solve the other issues.

Weller emphasized the Atlas’s goals are modest. To solve the complex issues facing these hotspots, planners and landscape architects must get on the ground and work with stakeholders to intelligently guide development. Now, at least, they have maps to point them in the right direction.

The Atlas for the End of the World

What’s left of the world’s biodiversity in protected areas / © 2017 Richard J. Weller, Claire Hoch, and Chieh Huang, Atlas for the End of the World, http://atlas-for-the-end-of-the-world.com.

Seen from 28,000 miles away, the earth is beautiful. But its beauty is deceptive. We don’t see the 5 billion tons of surplus carbon we pump into the atmosphere every year, our toxic waterways or our sprawling megacities and the vast fossil fueled monocultures of cattle and corn that feed them. Most importantly, we don’t see the global archipelago of protected areas into which the world’s genetic biodiversity is now huddled. On this Earth Day, 2017 we are launching a new atlas dedicated to examining this archipelago in detail. It’s called the Atlas for the End of the World.

The first atlas, the Theatrum Orbis Terrarum (The Theater of the World) was published in 1570 by the famous book collector and engraver from Antwerp, Abraham Ortelius. With his maps Ortelius laid bare a world of healthy – we can now say “Holocene” – eco-regions ripe for colonization and exploitation. Lauded for its accuracy, the Theatrum quickly became a best seller.

Despite its apocalyptic title, our new Atlas is not about the end of the world per se; it is about the end of Ortelius’ world, the end of the world as a God-given and unlimited resource for human exploitation and its concomitant myths of progress. On this, even the Catholic Church is now clear: “we have no such right” says Pope Francis.

At face value, atlases are just books of maps. The maps in the Atlas for the End of the World are however, quite specific. They specifically show the difference between the United Nations Convention on Biological Diversity targets for achieving 17 percent (global terrestrial) protected area by 2020 and what is actually today protected in the 398 eco-regions, which comprise the world’s 36 biodiversity hotspots.

The so-called hotspots are regions agreed upon by the scientific and conservation communities as the most important and the most threatened biological places on earth. They are also places of exceptional linguistic diversity, much of which is also predicted to disappear by century’s end — suggesting perhaps, that the fate of nature and the fate of culture is one and the same. Many of the hotspots are also bedeviled by poverty, violence and corruption.

When my research assistants and I began this mapping project in 2013, the world’s terrestrial protected area total was hovering at 13.5 percent. Recent figures (2015 data) suggest a total of 15.4 percent. That’s 20.6 million square kilometers of land distributed across more than 209,000 sites in 235 different countries. So, with 15.4 percent already secured, only an additional 1.6 percent protected area is needed to satisfy the Convention’s 2020 target. This amount might seem paltry, but 1.6 percent of the earth’s terrestrial surface is 2.3 million square kilometers, the equivalent of nearly 700,000 Central Parks. That’s a Central Park stretching 70 times around the world! The research question we asked was where exactly should this additional protected land be?

To meet UN protected area targets over 700,000 Central Parks need to be added to the world’s protected area estate. / © 2017 Richard J. Weller, Claire Hoch, and Chieh Huang, Atlas for the End of the World, http://atlas-for-the-end-of-the-world.com.

According to the Convention, we can’t just fence off 1.6 percent of Siberia, or some other place, and then say we’re done! The crucial words in the small print of the Convention are that the global protected estate must be “representative” and “connected.” In theory, this means 17 percent of each of the world’s 867 eco-regions should be protected and connected.

The Atlantic Forests hotspot serves as an example. Currently it has only 8 percent of its territory under protection. Furthermore, when we break the hotspot down into its 15 constituent eco-regions, we find that 9 fall short of reaching 17 percent representation.

An example of one of 35 of the world’s hotspots: The Atlantic Forests / © 2017 Richard J. Weller, Claire Hoch, and Chieh Huang, Atlas for the End of the World, http://atlas-for-the-end-of-the-world.com.

In total 21 of 35 hotspots currently fall short of reaching the 17 percent protected area target. More specifically, 201 of their 391 eco-regions fall short. With the new Atlas, any nation can know how much land needs to be protected and where if it wants to meet its obligations under the Convention. This is not to say that blanket targets are always appropriate on the ground, but, it’s a start.

In addition to identifying these protected area shortfalls, the critical nexus this research addresses is the global tension between food production, urbanization and biodiversity. On the world map (below) are three squares. The first and smallest is the world’s current crop land. The second, in the middle, is current crop land plus current grazing land, plus what is thought to be the world’s further potential supply of arable land – a total of 50 percent of the earth’s ice-free surface area. These leave 50 percent of the planet’s land for other uses, exactly what E.O. Wilson has called for in his book, Half Earth. 50 percent seems like a lot, but remember that 33 percent of this land is desert – land which by definition is not suited to either biodiversity or agriculture. Subtracting the world’s deserts leaves 17 percent for biodiversity – precisely the amount demanded by the Convention.

The bigger cause for concern is however the large square: the land area necessary to feed 10 billion people. The UN is now forecasting anywhere between 9.5 and 13.3 billion by 2100, so 10 is a conservative estimate. But these projected 10 billion consumers are not “average” global citizens; let us suppose they are people like us; who shop in supermarkets and eat more or less whatever they want, whenever they want. They are average Americans; people with a food footprint of 1.4 hectares each. 10 billion people consuming at this level would require a whopping 93 percent of the earth’s ice-free terrestrial surface. In this scenario, not only would all the world’s arable land be used for agriculture, but so too would the world’s deserts, plus some. After we’ve finished our burgers, a mere 7 percent of the earth’s terrestrial surface would be left for biodiversity – for all practical purposes a mountainous zoo in the midst of a global monoculture of corn and cattle, hooked up to desalination plants.

These proportions of land-use will likely change when global population drops, as it probably will in the 22nd century due to socio-economic influences associated with urbanization. The other mitigating factor would be if the bulk of food production shifted to the oceans, and/or if meat could be produced independently of ruminants entirely. Then, ecological restoration could take place on a scale commensurate with that which is needed to partially correct the earth system’s current imbalances.

The challenge will be to get through this century’s incredibly tight ecological bottlenecks and come out the other end with some ecosystems, preferably the hotspots, partially intact.

The second major area of this research concerns 422 cities in the world’s hotspots. We zoomed into each city of 300,000 people or more and superimposed their 2030 growth trajectory (as per Karen Seto’s work at Yale ). We then plotted remnant habitat and threatened (mammal) species from the International Union for the Conservation of Nature’s Red List. What emerges are the flashpoints between future urban growth and biodiversity.

In the circular images of the cities in the Atlantic Forests hotspot, orange indicates zones of imminent conflict between urban growth and biodiversity. Alarmingly, 383 of the 422 cities in the world’s hotspots are on a collision course with unique and irreplaceable biodiversity.

And we are not just talking about a little bit of sprawl. If an extra 3 billion people move into cities by 2100, as is entirely likely, it means we need to build 357 New York Cities in the next 84 years, i.e., 4.25 New Yorks per year. Much of that growth will occur as both formal and informal sprawl in Africa, India and South and Central America, much of it up against biodiversity and much of it unregulated.

As documented in the Atlas, our analysis suggests that most of these 383 cities that are encroaching on valuable habitat don’t have any semblance of as whole-of-city urban planning. This lack of planning at the city scale is also evident at the national scale: almost all the nations in whose jurisdiction the world’s hotspots lie don’t – in so far as we can tell – have national land-use plans incorporating biodiversity.

Under the Convention on Biological Diversity, each nation must develop a National Biodiversity Strategy and Action Plan. In practice, these tend to be platitudinous reports and most don’t take into account the 17 percent target for protected area. Most of the nations who are signatories to the Convention on Biological Diversity are also signatories to the Paris Agreement on Climate Change, which demands that they prepare national climate change plans.

The Atlas for the End of the World lays the ground work for the 142 nations who preside over the world’s biodiversity hotspots to now view climate change, biodiversity, and urbanization as interrelated phenomena and plan for the future. To do so would be a new beginning.

A New Strategy for American Sustainability

The New Grand Strategy / St. Martin’s Press

Back in 2009, U.S. Chairman of the Joint Chiefs of Staff Michael McMullen tasked his staff to create a “grand strategy” for the United States. That job fell to Navy Captain Wayne Porter and now-retired Marine Colonel Mark “Puck” Mykleby, who later turned the results from the multi-year research study into a book: The New Grand Strategy: Restoring America’s Prosperity, Security, and Sustainability in the 21st Century. At the Biophilic Leadership Summit at Serenbe, an agricultural community near Atlanta, Mykleby asserted that the United States is now deeply embedded in an “unsustainable global system” that makes it susceptible to shocks, particularly from climate change. In addition, we are stuck with a “20th century economic engine.” The way forward to future sustainability is found in walkable communities, regenerative agriculture, and greater resource productivity. “We need to rebuild our own strength and credibility by setting a new example.”

Mykleby — who was described by Serenbe founder Steven Nygren as a “gentle giant with a big heart who can kill you with two fingers” — outlined in drill sergeant mode all the things that make our current global system unsustainable:

First, there is the rapid inclusion of many new consumers around the world. As the planet heads towards 9 billion people, we can expect to see a middle class of around 3 billion people. If they are consuming as Americans and western Europeans do now, we will need 4.5 Earths to maintain them. Second, climate change and increasing ecosystem degradation will reduce our access to resources and increase our vulnerabilities. And, lastly, there is a growing “infrastructure resilience deficit” — infrastructure worldwide isn’t set up to accommodate the anticipated population growth or coming nature-driven shocks.

(Mykleby also argued that using gross domestic product (GDP) as the primary measure of progress is really enabling all this unsustainable global growth and needs to be replaced with a gross national happiness metric, like Bhutan’s. We’ve discovered in the United States that “more shit isn’t going to make us happier.”)

In addition to being embedded in an unsustainable global system, the U.S. is also stuck with an “obsolete 20th century economic engine,” defined by suburban sprawl, consumer spending, high-input agriculture, massive federal subsidies, and quarterly reporting and capital gains taxes. This engine is “extremely fragile.” Agricultural in particular is in a “perilous place,” given climate change. On top of all this, we have “political dysfunction.”

Walkable communities help rebuild American strength by increasing social ties, particularly inter-generational ones. As baby boomers downsize and want to age in place, they seek connections to others. Millennials can’t afford cars or don’t want them, so they are also want more walkable places. In fact, research shows “some 60 percent of the country seeks communities with the attributes of smart growth.” But given the market hasn’t met demand, people are still paying a premium to live in these places.

Food production will need to increase 60-70 percent in coming decades to meet the demand from a growing population, just as climate change accelerates and ecosystems are further degraded. The only way to achieve this is “100 percent regenerative agriculture. We need to restore our top soils.” (Mykleby didn’t further define regenerative agriculture in his talk, but we are assuming it involves permaculture, introducing perennial grain plants, and other sustainable farming practices).

Lastly, according to The Atlantic, some 70 percent of Indian cities have yet to be built. A similar number can be found for many developing world cities. And all our developed-world urban communities are in a continuous process of being rebuilt. As the global population heads toward 9 billion and concrete production already accounts for 5-10 percent of global carbon dioxide emissions, we need “more advanced, resource-efficient, recycled building materials.”

If the U.S. “can get its ass in gear,” focusing on walkable communities, sustainable agriculture, and new housing materials will lead to a resurgence in jobs in the manufacturing, agriculture, construction, transportation sectors, and create the “economy of the future.” Mykleby also called for changing from a model of rampant material consumerism to an economy in which “we consume positive, meaningful experiences.”

While the path to sustainability is clear to him, sadly, the U.S. is now “doubling-down on the old economy. We are walking away from climate change, increasing inequality, and leaving international institutions.” As the supporters of the old business model hang on tight, they are setting us up to fail.

If you are unconvinced the U.S. is falling behind, Mykleby urges you to read China’s latest five-year plan, which aims to set the country on a “sustainable path, address social equity problems, and increase participation in international institutions.”

India’s water crisis / National Geographic

As we look forward to covering new stories on the built and natural environments this year, here’s a look back at the 10 most popular Dirt posts of 2016. Extensive coverage of the Landscape Architecture Foundation (LAF)’s New Landscape Declaration attracted the greatest interest. Thought provoking op-eds on the summit from University of Pennsylvania (UPenn) landscape architecture department chair Richard Weller, ASLA, and UPenn graduate student Billy Fleming, Student ASLA, were also widely read. (Speaking of which, The Dirt is always looking for original op-eds, particularly from member landscape architects, designers, and planners. If interested, please email us at info@asla.org).

Also worth noting: innovative examples of ecological and biophilic design, along with the latest research on the health benefits of nature, drew readers. 

1) The New Landscape Declaration: Visions for the Next 50 Years

Over the next 50 years, landscape architects must coordinate their actions globally to fight climate change, help communities adapt to a changing world, bring artful and sustainable parks and open spaces to every community rich or poor, preserve cultural landscape heritage, and sustain all forms of life on Earth. These were the central messages that came out the Landscape Architecture Foundation (LAF)‘s New Landscape Declaration: Summit on Landscape Architecture and the Future in Philadelphia, which was attended by over 700 landscape architects.

2) Has Landscape Architecture Failed?

In 1966, Campbell Miller, Grady Clay, Ian McHarg, Charles Hammond, George Patton, and John Simonds marched to the steps of Independence Hall in Philadelphia and declared that an age of environmental crisis was upon us and that the profession of landscape architecture was key to solving it.

3) 10 Parks That Changed America

PBS will broadcast a new documentary, 10 Parks That Changed America, on April 12th. Produced by WTTW in Chicago and featuring Geoffrey Baer, the show identifies the 10 most influential urban parks in the country, from the era of America’s early settlers to the present day.

4) Biophilic Cities Lead the Way to Urban Sustainability

“We need density but we also need connections to nature,” said University of Virginia professor Timothy Beatley, at an event at the University of the District of Columbia (UDC) to celebrate D.C.’s successful inclusion in the Biophilic Cities Network, a group of leading cities pushing for rich, nature-filled experiences in daily urban life.

5) 15 of the Best Instagram Accounts for Landscape Architects

Instagram is a great way to get inspired, but there are over 500 million active accounts, so who should you follow? For landscape architects, fresh ideas can be found from following other landscape architects, but also those outside the field: artists, technologists, illustrators, and designers.

6) It’s Time to Get Political

Social justice. Environmental stewardship. Enduring aesthetic beauty. An expanded role for landscape architects. These were the predominant themes in the Landscape Architecture Foundation (LAF)’s Summit on Landscape Architecture and the Future at the University of Pennsylvania in Philadelphia.

7) Thomas Rainer: There Are No Mulch Circles in the Forest

Instead of laying down a layer of mulch to separate plants, let native plants grow into beautiful, layered masses, said Thomas Rainer, ASLA, co-author of Planting in a Post-Wild World, at the Potomac Chapter of ASLA Gala in Washington, D.C. Rainer believes it’s possible to both boost biodiversity and achieve beauty through the use of “designed plant communities.”

8) Best Books of 2016

There were so many great books this year that honing in on just ten favorites was too challenging. Whether you are looking for a unique book to give as a gift or one for yourself to delve into, we have some options. Here’s The Dirt‘s top 15 books of 2016, our picks for the best on the environment, cities, and landscape.

9) We Must Better Communicate the Health Benefits of Nature

While landscape architects, arborists, and park advocates, and an increasing number of mayors, planners, and public health officials, understand the presence of nearby nature in cities to be central to human health and well-being, the public seems to think of tree-lined streets, trails, and parks as “nice, but not necessary, add-ons,” according to a new report commissioned by the TKF Foundation and conducted by the FrameWorks Institute, a non-partisan research organization.

10) New Research: Students Learn Better in Classrooms with Views of Trees
What if what is outside a school’s windows is as critical to learning as what’s inside the building? A fascinating new study of high school students in central Illinois found that students with a view of trees were able to recover their ability to pay attention and bounce back from stress more rapidly than those who looked out on a parking lot or had no windows.

National Park Service Looks Ahead to the Next 100 Years

“National parks are the best idea we ever had. Absolutely American, absolutely democratic, they reflect us at our best rather than our worst.” — Wallace Stegner, 1983

The National Park Service (NPS) celebrates its centennial this year and is ready to move into its next 100 years by restoring its crown jewels and also embracing new parks and a diverse range of visitors. At the ASLA 2016 Annual Meeting in New Orleans, Barbara Wyatt, ASLA, NPS and the National Register of Historic Places: Landscape Initiative said, the service must “maintain natural, community, historic, and cultural elements” while upholding standards of excellence far into the future. The NPS now boasts of 412 units, including vast tracts of wilderness, important cultural institutions, monuments, and historic landscapes.

Susan Olmsted, ASLA, with Mithun explained efforts to restore one of the system’s jewels: the Mariposa Groves of giant sequoias in Yosemite. Her efforts are about “building resilience for this cherished place.” In the midst of one of the rarest ecologies in the world, there was a parking lot and a tram to accommodate all visitors. People were about to “love these trees to death.” Over a hundred years of fire suppression (natural fires were re-introduced in 1971) had also been a setback for the species. The health and well-being of the trees was put at the center of the restoration plan.

Places like these, which feed into the national imagination and “elevate the human spirit,” are some of the most important elements of the NPS experience. The Mariposa Grove is now on its way back to a healthy and long future and will re-open next summer.

The National Mall, as tapis vert, is in many ways the opposite of the Mariposa Groves at Yosemite, but is no less important to the national imagination as the soaring heights of the giant Sequoia. We gather there for inaugurations and to hear the rallying cry of leaders calling for civil rights. It is, in a sense, the front lawn for all Americans. But with 30 million visitors a year and over 3,000 officially-permitted uses, it was in need of rehabilitation.

Michael Stachowicz is the only turf management specialist on NPS’ staff, and recognizes the importance of keeping the Mall green and healthy. The rehabilitated lawn was “designed for modern use while keeping its historic character.” Millions of feet over many years had caused serious soil compaction, terrible drainage, and patchy green. His rehabilitation efforts included thoughtful grading, specially-grown sod from seed, drainage systems, stormwater cisterns, and engineered soils. His maintenance policy has moved from “damage repair to damage prevention.” He acknowledged sometimes the best thing you can do is ask people to “keep off the lawn.”

Phil Hendricks, ASLA, Robert Peccia & Associates, offered his experience in the creation of one of the newest units in the system: the Waco Mammoth National Monument, in Waco, Texas, as well as his restoration work at the Flamingo Visitor Center and Campground in Florida’s Everglades National Park. Both parks refer back to well documented NPS styles guidelines. The original “park rustic” design was applied to Waco Mammoth, and the Flamingo Resort was restored to mid-century “Mission 66” style, even down to a new coat of flamingo-pink paint.

The NPS seeks to embrace a broader constituency of visitors across its ever expanding urban and natural landscapes, cultural heritage sites, and monuments. With its increasing embrace of public-private partnerships, it’s also finding the funding to continue into its next century. This land is your land, go out and see it.

The Road to Recovery May Be Green

Can spending time in nature help heal veterans with post-traumatic stress disorder (PTSD) and traumatic brain injury? As suicides from PTSD sufferers only increase, the Institute for Integrative Health (TIIH) seeks out answers to this important question through their new Green Road project, which just opened at the Naval Support Activity Bethesda, home of Walter Reed Military Medical Center, in Maryland.

In the middle of the vast medical and university campus, the Green Road takes patients, nurses, and staff down a zig-zaging path to a healing woodland garden, a beautiful 2-acre valley, which used to be a golf course, but now feels wild. The restored forest and stream are at the heart of the experience.

And these restored places are the source of the vista seen from two new, open-air cedar and steel pavilions.

The landscape was designed and built by a team led by CDM Smith, including landscape architect Jack Sullivan, FASLA, and his students at the University of Maryland.

The idea for the project came from retired U.S. Navy neurologist Frederick Foote, M.D., now a scholar at TIIH. His vision was to bring back an ancient idea: using nature to heal. As Foote explained, four different teams of scientists — from the Arizona Center for Integrative Medicine, University of Tucson; Benson-Henry Institute of the Massachusetts General Hospital; Consortium for Health and Military Performance, Uniformed Services University of the Health Sciences; and National Institute of Health Clinical Center, Pain, and Palliative Care Services — will undertake in-depth studies in the Green Road to “isolate where nature has the most effect.” Some $1.1 million in research will be conducted, all made by possible by the smart and impactful TKF Foundation, which provided some $1.1 million towards the $3.2 million project.

Walking down the path, one of the first things visitors notice are the massive logs strewn through the garden. At first, I thought their intention was ecological: to regenerate the soil and create habitat for small creatures. But, as Foote explained, the dead trees are also symbols of fallen soldiers. Often, soldiers experience PTSD because they have lost a close friend in battle. The logs are opportunities for those suffering with PTSD to remember those they’ve lost in a more gentle, natural way and connect death with the positive cycle of regeneration.

Throughout, the garden brings in elements that veterans, both with PTSD and without, identified were important to them. As Sullivan explained at the opening ceremony, design charrettes were conducted with 30 veterans to figure out how the natural beauty of the stream and forest could be enhanced to create a healing effect. “They wanted both a solitary place where they could get away and find solace nature, and a special place to meet others to commemorate those who had fallen, a place to get together with family and comrades.”

The landscape restoration was extensive. Invasive plants were removed and 58 new trees were planted, including river birch, pin oaks, and magnolias. Summersweet shrubs, which will bloom in summer, were planted in abundance. Still, the restored stream, done by Angler Environmental, is perhaps the major attraction. One bank was stabilized, trees were cut back, and the other eroding bank will be restored next.

Foote explained that “the Green Road features stone, water, trees, and animals. Through design, they are paired in new ways. We believe these paired natural systems can help heal PTSD.”

Foote looks to nature for solutions, perhaps because he has spent decades witnessing the failings of modern medicine to solve PTSD in wounded warriors. “We have been trying to heal people one organ at a time with pills and surgery.” But the problem is that PTSD “doesn’t respond to those treatments, so we need to try holistic approaches.”

That move towards holistic medicine — which the Greeks of ancient times and the Chinese of today still practice — has been a slog. “Our cultural obsession with technology means we underestimate holistic therapy.” Mainstream medical practitioners undervalue it, because, to date, it has been impossible to measure “whole body effects, mathematically.” They can only measure with confidence that this treatment or that pill yields results on this or that organ.

Foote sees the future in creating proof of the benefits of holistic approaches: a set of “whole body metrics” that could be used to test and measure the effect of these treatments for PTSD and other disorders. Foote wants to apply many technologies and approaches to forge these new metrics: genomics, which would look at which genes are turned on during PTSD and what can turn then off; artificial intelligence-based textual analysis of patients’ writings to categorize and diagnose their disorders; integrated biometrics of stress to measure physiological effects of suffering and also treatments; and big data analyses to find more accurate sub-groups for evaluation. Foote hopes the Green Road can help test these nascent “whole body metrics,” at least for the metrics and potential treatments related to exposure to nature. “I hope this becomes the national laboratory for studying how humans interact with nature.”

Trees and people / Jared Green
Humans and nature / Jared Green

His plan is that a group of 50 veterans, some suffering from PTSD and some not, will be studied in the Green Road. Their physiological response to the place will be measured in detail. “We could ask a group to spend an hour in the Green Road on a scavenger hunt, and then the next day, they could do the same on the streets and we could measure the differences in their responses.”

While the Green Road is a major success, the only criticism is that it’s hidden behind buildings and parking lots, and there is no signage to explain how to get there. It’s a good 15 minute walk from the medical facilities. For patients, it’s a destination, not a place to simply wander into. Walter Reed will need to further promote to ensure it’s well-used by the people who need it. Asked whether Walter Reed will actually prescribe patient time there or conduct horiticultural therapy sessions there, Foote seemed a bit pessimistic, pointing to limited budgets. “We need $2 million, $5 million to do everything.” But he does see the Green Road hosting events and therapeutic exercises.

His grand vision for sometime in the near future is beautiful: sufferers of PTSD will wear a device like a Fitbit that would measure whole body responses and would let them know when they are getting stressed and alert them to go spend time in a park. A fascinating mix of ancient wisdom and new technologies.

ASLA Launches Guide to Resilient Design

Resilient design / ASLA
Resilient design / ASLA

A new online guide launched today by the American Society of Landscape Architects (ASLA) explains how communities can better protect themselves from natural disasters through resilient landscape planning and design.

According to the guide, the goal of resilient landscape planning and design is to retrofit communities to recover more quickly from extreme events, now and in the future. In an era when disasters can cause traditional, built systems to fail, adaptive, multilayered systems can maintain their vital functions and are often the more cost-effective and practical solutions.

The guide is organized around disruptive events that communities now experience: drought, extreme heat, fire, flooding, and landslides. Biodiversity loss is an underlying threat also explored.

The guide includes hundreds of case studies and resources demonstrating multi-benefit systems as well as small-scale solutions. It also explains landscape architects’ role in the planning and design teams helping to make communities more resilient.

Resilient design involves working with nature—instead of in opposition to it. It provides value to communities, including:

Risk reduction: As events become more frequent and intense due to climate change, communities must adapt and redevelop to reduce potential risks and improve ecological and human health. It’s also time to stop putting communities and infrastructure in high-risk places. And communities must reduce sprawl, which further exacerbates the risks.

Scalability and Diversity: Resilient landscape planning and design offers a multi-layered system of protection, with diverse, scalable elements, any one of which can fail safely in the event of a catastrophe.

Multiple Co-Benefits: Resilient landscape design solutions offers multiple benefits at once. For example, designed coastal buffers can also provide wildlife habitat and recreation opportunities; urban forests made up of diverse species clean the air while reducing the urban heat island effect; and green infrastructure designed to control flooding also provides needed community space and creates jobs.

Regeneration: Disruptive natural events that are now occurring more frequently worldwide harm people and property. Resilient design helps communities come back stronger after these events. Long-term resilience is about continuously bouncing back and regenerating. It’s about learning how to cope with the ever-changing “new normal.”

In an era when disasters can cause traditional, built systems to fail, adaptive, multi-layered systems can maintain their vital functions and are often more cost-effective and practical solutions. In an age of rising waters and temperatures and diminishing budgets, the best defenses are adaptive, like nature.

The guide to resilient design has been strengthened through the expert guidance of Alexander Felson, ASLA, assistant professor, School of Forestry & Environmental Studies and Yale School of Architecture; Kristina Hill, Affiliate ASLA, associate professor of landscape architecture and environmental planning and urban design, University of California at Berkeley; Nina-Marie Lister, Hon. ASLA, graduate program director and associate professor, Ryerson University School of Urban and Regional Planning; Nate Wooten, Associate ASLA, landscape designer, OLIN; and Kongjian Yu, FASLA, founder and dean, Peking University College of Architecture and Landscape and Turenscape.
