In a country where 71 percent of the population lives in extreme poverty and nearly everyone depends on rain-fed agriculture, maize is Malawians’ lifeblood. Yet climate change threatens this critically important crop.

The Famine Early Warning Systems Network (FEWS NET) predicts that maize yields will decrease by 10 percent this year due to the combined effects of a prolonged drought and the invasion of a maize-destroying armyworm introduced from Latin America. It’s just the latest setback in the country’s long history of food insecurity: According to the International Monetary Fund, 65 percent of all households in Malawi (84 percent of rural households) reported experiencing food insecurity for at least one month of 2013, a 15 percent increase from 2010.

Satellite and other data reveal one strategy that could help—restoring degraded landscapes.   

The Global Adaptation Score Index rates countries on their vulnerability to climate change and ability to improve resilience. The lower the score, the greater the vulnerability. Malawi scores a 38 out of 100. Learn more by exploring the Vulnerability to Climate Change Index on Resource Watch.

 

Improving Food Security with Forest Landscape Restoration

Malawi launched its National Forest Landscape Restoration Strategy last year. A key goal is to improve food security through implementation of agricultural technologies, which is a type of forest landscape restoration.

The practice involves increasing tree cover on degraded, low-yield croplands through climate-smart farming practices such as farmer-managed natural regeneration and agroforestry. Increasing tree cover on croplands naturally stabilizes soil from erosion and increases nutrient availability without the use of costly and environmentally-damaging fertilizers. According to an analysis in the National Forest Landscape Restoration Assessment, there are 3.7 million hectares (9.1 million acres) of land in Malawi (39 percent of the entire country) that could benefit from the application of agricultural technologies that improve crop yields.

So where can these agricultural technologies be best deployed?

Overlaying a map of opportunity for agricultural technologies with a map of areas predicted to be most susceptible to food insecurity between June and September of 2018 (available via FEWS Net and Resource Watch), reveal that there are nearly 430,000 hectares of cropland in high-risk areas that could have their yields increased through climate-smart agricultural technologies. Focusing implementation on areas that are regularly at risk for food insecurity could increase the availability of crops for more than 1 million people, improving nutrition and reducing reliance on humanitarian aid over the long term.

Where else in the world can forest and landscape restoration be applied? Check out the Forest and Landscape Restoration Opportunities Map on Resource Watch.
