Food systems must be transformed to produce more nutritious food with a lower environmental footprint. There are a number of initiatives around the world working towards this end. Here are just five that use different kinds of science—from smart approaches to breeding livestock and crops to recycling wastewater—that could help humans settle their growing debt to the planet.
The implementation of effective mitigation strategies relies on accurate GHG emission data. But what if the underlying assumptions upon which these GHG emission estimates are based are inaccurate?
In 2015–2016, the International Livestock Research Institute (ILRI) and partners revealed extraordinary findings that the greenhouse gas (GHG) emissions from cattle in Kenya maybe up to 10 times lower than previous estimates, clearly making the case for improving Africa-specific understanding of GHG emissions to develop better-targeted climate change mitigation and adaption strategies.
What might seem like a silver bullet to reduce greenhouse gas emissions risks undermining other development goals such as ending hunger, improving health and eliminating poverty. We cannot ignore the important role that animal-source foods play, especially in developing countries, when we talk about tackling climate change. Instead we need to find a middle ground.
Greenhouse gases emitted by Kenyan cattle excreta are found to be much lower than estimates derived from models in industrialized countries.
Cattle and figures, Laas Geel cave complex, Somaliland, Somalia. This opinion piece is written by Alain Vidal, director of strategic partnerships at CGIAR. Our global food production system—which includes, in addition to crop farming, raising livestock and deforesting lands to grow livestock feed and other crops—is responsible for about a quarter of the greenhouse gases produced …
