Biochar Is ‘Low-Hanging Fruit' for Sequestering Carbon and Combating Climate Change

As institutions look for ways to fight climate change, the College of the Atlantic has made the search for solutions a central part of its curriculum.

Geography and climate change challenge the viability of sea-level cities in Vietnam, but architects, researchers, and urban planners work together to find creative solutions. One architect in Ho Chi Minh City designed green roofs to absorb the rainwater that causes floods.

What we sometimes call the “agri-food system” is broken — just ask farmworkers and food workers (exploited, underpaid), honeybees (collapsing), forested landscapes (fragmenting), the climate (warming), and the ever-growing number of people without access to nutritious food, or the land and resources with which to produce it. But a new branch of sustainability, agroecology, helps farmers and researchers develop farming practices that enhance soil fertility, recycle nutrients, optimize the use of energy and water, and, perhaps most importantly, increase the beneficial interactions of organisms in ecosystems.

In India, many farmers, especially women farmers, have transitioned to organic farming. While it requires a serious set of skills and knowledge, organic farming increases yields and decreases costs by eliminating the need to buy pesticides. The move is both ecological and economical, and the Indian government is trying to spread the solution.

Property rights, circumscribed jurisdictions, and conflicts with neighbors exacerbate Native American efforts to restore tribal land and resources. Some tribes have found success by tapping into a trend of support from the government and conservationists.

Farmland is expensive and scarce in urban areas. In Boston Higher Ground Farm uses green roofs to grow its produce and Grove Lab has designed a cabinet for people to grow their vegetables indoors.

More than 30-meters below the busy London streets, there is an eco-farm called Growing Underground that's part innovative agri-tech project and part sci-fi inspired netherworld. Created to provide increased food security and combat the environmental degradation caused by mass agriculture, this self-contained, zero-emissions, fully functioning farm provides an exciting opportunity as the world's population grows and food demands increase.

The government wants more farmers turning waste methane into biogas to help combat the negative effects of global climate change. California is leading the initiative, largely through a cap-and-trade program.

In Australia, the Murray-Darling Basin Ministerial Council was formed after a severe drought to bring together federal, state and regional governments and bridge parochial concerns. It was meant to manage the basin as a whole and end overuse and salinization of farm land, leveraging new technologies to adapt to new realities.

A Kenyan government initiative is helping a growing community of residents to tackle food insecurity in one of the largest slum areas in Africa, championing an unusual form of urban farming: sack gardens.
