Postcard from the Field: Greening the Desert

By Climatelinks

Illegal alluvial gold mining in Colombia is a complex phenomenon that not only sweeps away vegetation but alters the balance of ecosystems through aggressive mechanical extraction methods that create deserts. In Antioquia, Colombia, this has degraded over 45 thousand hectares of land, stripping away valuable trees that can absorb carbon dioxide, one of the main greenhouse gases. The USAID-Oro Legal Activity brought together indigenous and Afro-Colombian communities, the private sector, and local and departmental governments to mitigate the environmental impact of uncontrolled mineral exploitation on more than one thousand hectares of degraded ex-mining land. Today, more than 1.1 million Acacia mangium trees and other native species are greening large tracts of land where just a few years ago, only rocks and bare soil could be found.

Postcards from the field features submissions to the Climatelinks photo gallery. This photo was submitted to the “Protecting natural systems in a changing world” category of the 2019 Climatelinks photo contest. The Climatelinks community is encouraged to submit new photos to the gallery through this submission form.

After many years of partnering with the U.S. Department of Energy's (DOE's) national laboratories on various energy sector studies and programs, the United States Agency for International Development's (USAID's) mission in India realized an opportunity to coalesce these initiatives into an interlaboratory consortium.
The U.S. Government’s Feed the Future program is making climate change a central objective of their strategy. Global food security is under stress from increasingly intense and frequent heat waves, droughts, heavy rains, and major storms, according to the new report by the United Nations Intergovernmental Panel on Climate Change, which issues a dire warning of the risks posed with every incremental increase in global warming. Using Climate Smart Agriculture (CSA), Feed the Future helps farmers adapt to climate variations, mitigate greenhouse gas (GHG) emissions, and build resilience to climate shocks.
To address these challenges, USAID partnered with the Sustainable Ocean Fund (SOF), to make pioneering impact investments into marine and coastal projects and enterprises. The $132 million Fund invests in projects across Latin America and the Caribbean, Africa, and Asia and the Pacific that aim to build resilience in coastal ecosystems and create sustainable economic growth and livelihoods in the blue economy.
