In Sowing Beauty: Designing Flowering Meadows from Seed, James Hitchmough tells us about what we’ve lost. “Meadow-like vegetation” was once “much more abundant.” He traces its decline to industrial agriculture and development.

Hitchmough saw the design potential of meadow communities early in his career as a horticultural ecologist. He has spent the last few decades studying their characteristics and experimenting with their composition. The resulting knowledge compiled in Sowing Beauty will push meadow design forward.

Planting meadows is a departure from planting gardens. It isn’t planting with particularity; it’s painting with broad strokes. That isn’t to say meadows lack sophistication. Change can be observed in sown communities, and there is “nearly endless variation.” Spontaneity informs meadow communities more than gardens, which partially explains their charisma.

Artistic intention in the design of meadows appears through seed mixes, what you scatter on the soil to materialize a meadow. A good seed mix requires an understanding of how natural meadow communities occur and function. However, seed mixes don’t have to have to be identical to naturally-occurring communities. Hitchmough encourages experimenting with seemingly incongruous seeds to produce novel results.

“The choice of plants is the central challenge in all planting design,” Hitchmough writes. The planting site must factor heavily into any decisions. Meadows are complex communities, with ground, middle canopy, and upper emergent layers to consider.

Management of meadows must also be considered. Cutting helps manage weeds, but the cut material must be removed. Other practices, such as grazing and mowing are more suitable in some climactic zones or scales.

The complexity of meadows offers a lot of opportunities for the meadow designer, but also several possible pitfalls. Sowing Beauty, gracefully, does not deal in vagaries. Need to know a handful of species with high-design potential found within Rocky Mountain steppe communities? That’s on page 77.

The back half of the book is composed of case studies of Hitchmough’s own projects. Each case study is documented with species used, target numbers for seedlings, and the total plants required for each project. The projects discussed range in scale a from a couple hundred feet to over 24 acres (Queen Elizabeth Olympic Park in London). Each study has a “What Worked and What Didn’t” section, where Hitchmough discusses in detail the successes and failures of the project.

At one point during the film, I Heart Huckabee’s, the main character, an environmental activist, bemoans the over development of our landscape to the point “you can’t remember what happens when you stand in a meadow at dusk.”

“What happens in the meadow at dusk?,” asks an earnest Jonah Hill.

Some of us might smile at Hill’s ignorance, but too many others can relate. It would be wonderful if the advice and knowledge offered in Sowing Beauty resulted in many more of these endlessly-interesting and beautiful landscapes.

Visions for the Next Generation of American Infrastructure

In March, the American Society of Civil Engineers (ASCE) released its infrastructure report card, the first in four years. After crunching the data, they gave the U.S. a D+, explained Tom Smith, executive director, ASCE, at the American Society of Landscape Architect (ASLA)’s mid-year board meeting. “We have a lot of infrastructure at the end of its useful life. And we have a $2 trillion infrastructure investment gap over the next decade.”

Given America’s infrastructure is nearly failing, how should we rebuild? And where do we find the money?

In a panel moderated by ASLA CEO Nancy Somerville, Hon. ASLA, Smith argued “we can’t just rebuild our grandparent’s infrastructure. We can’t just add more lanes to the highways. We need to focus on land-use planning, sustainability, and resilience. Autonomous vehicles will also be huge.”

Patrick Phillips, Global CEO, Urban Land Institute (ULI), said compact transit-oriented development could “reduce the need for infrastructure.” He believes infrastructure in the future needs to be more smartly targeted to achieve economic development goals but also improve equity. A focus on inclusiveness can lead to new possibilities and a fairer future.

Rachel Minnery, senior director of sustainability policy at American Institute of Architects (AIA) wants to see new infrastructure investments help deal with climate challenges by improving our resilience. “We have a vast stock of existing buildings” that must be made more resilient. “We need a new era of visionary planning.”

“Parks and green infrastructure should be an investment priority,” said David Rouse, ASLA, research director at American Planning Association (APA), echoing APA’s official position on infrastructure. “Green infrastructure creates jobs. We can’t just recreate grey infrastructure.”

And Roxanne Blackwell, Hon. ASLA, director of federal government affairs, ASLA, agreed, arguing that more investment is needed in “parks and national lands, which are also infrastructure.” National parks in particular are “overburdened,” said Smith, who noted that parks went down in the latest ASCE infrastructure report card. He added: “treating parks as infrastructure is an idea that resonates with people.”

Blackwell also made the case for increasing investments in “active transportation,” a term for infrastructure such as sidewalks and bike lanes, arguing that any major infrastructure investment must be comprehensive, and not just be about repairing highways and bridges.

So how to pay for the many trillions required for new infrastructure?

While states — even red ones — have raised gas taxes, the federal government hasn’t in decades and isn’t likely to in the future. President Trump has called for an increase in private investment in infrastructure through public-private partnerships (PPPs), but Somerville noted that PPPs usually privilege communities that can easily attract private investment. A private-sector led approach can then be expected to be leave poorer communities farther behind.

Phillips said there is “no silver bullet. We need a mix of private and public funds. Other countries are more effective at PPPs than us. Infrastructure can unlock opportunities in poorer neighborhoods. But, if poorly structured, a PPP doesn’t help.”

Minnery thinks the market will shift development and infrastructure investment patterns. Already the credit ratings of cities on coasts, which are most vulnerable to rising seas and storms, are taking a hit. As climate refugees increase in number and head inland, those cities will face pressure to increase development. “We have to think holistically as a nation about what this means.”

And, lastly, President Trump wants to speed up the process of building infrastructure. He is considering a new rule to requires states to start projects within 90 days of receiving federal funding. Is this possible?, Somerville asked.

Minnery said there’s often a delay at the state level, because of a lack of resources in planning departments. These departments have huge stacks of projects awaiting review. “Planning departments never recovered from cuts after the 2008 recession.” Rouse also noted that if the planned EPA cuts go through, “that stack of project reviews will get even higher.”

He said “successful infrastructure projects are rooted in local visions and strong regional planning.” To move projects forward quickly, communities must have planning infrastructure in place.

Blackwell wondered if more infrastructure project review responsibilities could be devolved to states. Through the FAST Act, federal lawmakers enabled California, Florida, Ohio, Texas and Utah to conduct their own National Environmental Policy Act (NEPA) reviews on behalf of the federal government. The Hill reports that Ohio saved $4.6 million in the first three months of doing the reviews itself.

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.

Paul Butler and St. Lucia parrot / Rare

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.

D.C. Becoming More Sustainable, But Not Everyone Benefits

It has been four years since Washington, D.C. released its ambitious sustainability plan, which called for cutting greenhouse gas emissions by 50 percent; increasing the share of trips made via walking, biking or transit to 75 percent; and making 100 percent of the district’s waterways fishable and swimmable — all by 2032. Since then, the district government has accomplished 72 percent of the things it set out to do. And it has made solid progress on the toughest goals. Already, greenhouse gas emissions are down 24 percent, based on 2006 levels, despite four consecutive years of economic and population growth.

At the launch event of Sustainable DC 2.0, district department of the environment and energy director Tommy Wells, outlined the top 10 achievements made by the city since 2013:

#10: Over 100 partners have pledged to help reach the Sustainable DC goals, including all universities in the district and nearly 100 embassies.

#9: The city now have 80 miles of bike lanes and 420 Capitol bike share stations. Some 16.7 percent of the populace now walks or bikes to work. D.C. is tied with Boston for 4th place in this regard, but Wells is confident D.C. will eventually beat Beantown. “I mean, we have much better weather.”

#8: The East Capitol Urban Farm, a three-acre facility that offers access to healthy food and job training. The district has a total of eight urban farms, more than 60 community gardens, and 120-plus school gardens. These efforts and others have helped make 82 percent of the district population food secure.

#7: A new zero waste plan. A comprehensive study now underway will help the city reduces its waste output, which is where the Economist Intelligence Unit said D.C. need to show the greatest progress five years ago. Wells said there are now composting facilities in every ward.

#6: District sustainability awards. Each year, the district government honors those who are leading partners in the effort to achieve the city’s goals. In 2016, American University, Atlas Brew Works, Compost Cab, and others won.

#5: The district now has the most energy star-certified buildings and the most LEED buildings  in the nation on a per capita basis. And for the first time, D.C.’s new comprehensive plan includes a sustainability section.

#4: D.C. is ahead of its goals in planting enough trees to reach a 40 percent tree canopy by 2032. The District is now at 38 percent, up 2 percent in the past year when 14,000 trees were planted, which together would cover 800 football fields or two National Malls. Wells gave a shout-out to Casey Trees, ASLA, and American University for helping to accelerate progress.

#3: The Anacostia River is now cleaner than it has been in years, in part due to the 2.7 million square feet of green roofs that help keep stormwater out of the river. Wells was confident the Anacostia can be swimmable and fishable by 2032, “maybe even 2025.”

#2: Sustainable DC ambassadors and volunteers. The district department of energy and the environment has trained over 125 people to go out into their communities and help make the case for sustainability.

#1: D.C. now gets 125,000 megawatts hours from regional wind power sources and 11 megawatts from rooftop solar facilities. 100 percent of D.C. government is now powered by renewable sources. The goal is for 50 percent of the entire district to be powered by wind and solar by 2032; the city’s now at 13.6 percent.

While D.C.’s renewable energy goals take us in the right direction, Hawaii has announced it will aim for 100 percent renewable energy, and Vermont, 75 percent. Portland, Oregon, also recently announced its intention to reach 100 percent renewable. Maybe it’s time for D.C. to up its game a bit?

In a panel after Wells’ announcement, Greater Greater Washington founder David Alpert moderated a panel with former D.C. planning director Harriet Tregoning, Nature Conservancy urban conservation director Khalil Kettering, and Black Women Bike founder Veronica O. Davis, exploring how sustainability relates to resilience, inclusiveness, and health and well-being, and where D.C. needs to go next.

Tregoning said a key issue was D.C. and other big cities are no longer “producing middle class jobs; they are just creating jobs at the high-end — knowledge workers — or at the low-end in restaurants or retail.” She has a plan to resolve this: “If 5 percent of D.C. buildings were retrofitted each year, that would create more middle class jobs and grow the housing and construction economy.” Efforts like these are needed more than ever, particularly given the U.S. shed 89,000 retail jobs since the beginning of the year, and cities like D.C. are “automating the low-end jobs that used to be done by people.”

Davis focused on the need more thoughtful inclusiveness efforts, arguing that educational programs aimed at encouraging African Americans in Ward 7 and 8 to use Capitol bike share have been patronizing. “We’ve been doing bike share for years. It’s called: ‘Let me hold your bike while you go into the store.'” She also said training and education on sustainability isn’t needed in many instances, because African American residents in D.C. are really already living in a sustainable manner, walking or biking to work, or using the Metro.

And Kettering zoomed out to look at the systems-scale, arguing that when looking at sustainability, cities need to look at human health and well-being, housing, and transportation together. The relationship between all of the elements that go into sustainability are “constantly evolving. There are layers of issues and benefits” changing in tandem.

D.C. still has many challenges to overcome in its effort to become truly sustainable. According to a recent report, it’s the 17th most segregated city in the country. In 2013, some 18.9 percent of the population lived below the poverty line, putting D.C. among the top six states and territories of the country with the highest concentrations of poverty. And the poverty rate east of the Anacostia got even worse after the recession.

For Tregoning, the problem is that the federal government, even prior to the Trump administration, has told basically told cities “you are on your own,” so there is even “less federal support.” Given the market “doesn’t create fairness and equity,” cities have to be deliberate in creating policies that can. Mayor Muriel Bowser has increased investments in affordable housing, but some argue the city’s efforts don’t go far enough.

Ending poverty on the east side of the Anacostia will take a sustainability plan that delivers on new green jobs. Sustainability and equality must be considered two sides of the same coin.

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 Environmental Protection Agency (EPA) requests public comment on recent executive orders to eliminate federal programs and policies that protect and preserve our planet’s sustainability, including policies to address climate change and mitigate its impacts.

Help us uphold landscape architects’ long-standing value of stewardship for the natural environment. Sign onto ASLA’s letter to Environmental Protection Agency Administrator Scott Pruitt, urging him to reconsider recent actions that will endanger our planet.

ASLA wants to submit the letter signed by at least 1,000 landscape architects into the official record of public comments on Presidential Actions Related to Regulatory Reform.

Take action—sign the letter today!

Official Letter text:

Dear Administrator Pruitt:

We, the undersigned landscape architects, submit the following comments in response to your request for public input on Presidential Actions Related to Regulatory Reform.

As landscape architects who lead in the stewardship of our natural environments, we are extremely concerned about recent actions taken by the administration to eliminate federal programs and policies that protect and preserve our planet’s sustainability. In particular, we strongly object to activities that roll back U.S. climate policies, undermine the collection and dissemination of climate science and data, and withdraw the United States from the United Nations Framework Convention on Climate Change (UNFCCC) Paris Agreement. These actions not only endanger our natural resources, but they also jeopardize our vulnerable economy and threaten national security.

Recently, President Trump issued an Executive Order to review the Clean Power Plan, rescind several climate-related regulations and reports, reverse the moratorium on new mining leases on federal land, and overturn other climate-related federal activities. The order also revokes the President’s Climate Action Plan, which called on the federal government to make “climate-resilient investments” through agency grants and technical assistance to local communities. Together, these actions completely abandon the United States’ road map to achieving emissions reductions, and leave local communities vulnerable to the destructive impacts of climate change, including worsening air pollution, heat waves, poor water quality, coastal erosion, sea-level rise, wildfires, drought, and other devastations.

Landscape architecture combines science and design to plan and protect a variety of outdoor spaces, including multimodal transportation networks, water and stormwater management systems, parks and outdoor recreational facilities, residential communities, commercial developments, and more. Our profession understands the importance of and relies on credible science and data, which heightens our concern for recent administration recommendations to cut funding for critical federal scientific research and development programs, particularly climate science programs. Many of these programs diagnose the causes of the changes in the Earth’s climate system, but they also provide solutions and technologies to mitigate the risks from climate change while creating new economic opportunities for the nation.

Climate change is one of the greatest threats to our planet and our nation, but can also be a catalyst for great economic opportunities. Employing more green infrastructure projects and low-impact development, increasing active transportation networks, creating more parks and open spaces, using alternative energy sources like solar and wind are just a few climate mitigation techniques that also create new economic opportunities, including local jobs.

We are also concerned about recent threats to withdraw the United States from the Paris Agreement on global climate change. This landmark accord would strengthen the global response to the threat of climate change and the ability of countries to deal with its devastating impacts. The United States should continue to honor its global commitment to the agreement and take every action possible to achieve its principles and goals.

We urge you, as the major federal official charged with protecting and preserving our natural resources, to change course and work to continue federal carbon reduction programs and regulations, fund scientific research and make it accessible to the American people, and honor the United States’ commitment to the Paris Agreement. Thank you for this opportunity to provide comments on this critical issue.

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?

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.

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.
