A multimedia approach to extension services has helped increase the uptake of Sustainable Agricultural Intensification (SAI) in Ghana, Nigeria, Tanzania and Uganda as part of the African Soil Health Consortium’s (ASHC) scale-up campaigns focused on the key crops of maize, common bean, soybean, cassava, potato and banana.

The capacity of coral reefs to provide ecosystem services such as food and jobs, relied on by millions of people worldwide, has declined by half since the 1950s, according to a new University of British Columbia-led study. Other findings are equally bleak: the authors found that global coverage of living corals had declined by about half since the 1950s and consequently, the diversity of species had also declined, by more than 60 per cent. Finding targets for recovery and climate adaptation would require a global effort, while also addressing needs at a local level, authors say.

Coral reefs around the world are under threat because of climate change, overfishing, pollution, and more. Now, researchers reporting in the journal One Earth on September 17 offer the first comprehensive global look at what these impacts on coral reefs mean for ecosystem services, the ability of the reef to provide essential benefits and services to humans. Overall, the findings show that the significant loss in coral reef coverage has led to an equally significant loss in the ability of the reef to provide basic services, including food and livelihoods.

For the first time, scientists have assembled a quantitative assessment for agriculture sustainability for countries around the world based not only on environmental impacts, but economic and social impacts, as well. The Sustainable Agriculture Matrix, or SAM, provides independent and transparent measurements of agricultural sustainability at a national level that can help governments and organizations to evaluate progress, encourage accountability, identify priorities for improvement, and inform national policies and actions towards sustainable agriculture around the globe.

According to the authors of “Sustainable Food Systems and Nutrition in the 21st Century: A Report from the 22nd Annual Harvard Nutrition Obesity Symposium,” “there are vast opportunities to ensure that food systems produce healthy and safe food in equitable ways that promote environmental sustainability, especially if the world can come together at the UN Food Systems Summit in late 2021 and make strong and binding commitments towards food system transformation.”
