How agroforestry can help farmers adapt to climate change

Farmers have been on the edge to practice climate-smart farming activities to curb climate change conditions experienced in the country.

Kenya is now experiencing warmer temperatures, rainfall variability and increased severe and frequent extreme weather changes.

The country is also facing the challenge of locust invasion that is expected to decrease food production.

Agroforestry is a land-use management system in which trees or shrubs are grown around or among crops or pastureland.

It helps to improve soil, fertility, soil structure, retain soil moisture, protecting the crops and increase crop yields.

Due to food shortages and increased climate threats, Tannis Thorlakson of Harvard’s Sustainability Science Program and Henry Neufeldt, head of climate change research at the World Agroforestry Centre (ICRAF) explored just how agroforestry can help reduce farmers’ vulnerability, using a farmer-managed agroforestry project developed by ICRAF and located in the Nyando District of western Kenya.

“The study compared two farmers involved in agroforestry development projects for two years and 4 years for neighbouring farmers without agroforestry training,” Says Tannis Thorlakson.

Farmers exercising agroforestry recorded an increase in dairy production, improved farm productivity, income diversification and environmental sustainability.

Here are discussed ways that agroforestry can help farmers adapt to climate change:

Improving dairy production

Farmers can grow calliandra trees used to feed their livestock since it increases yields in milk. Calliandra tree is a folder crop that has high amounts of proteins required by cattle for the production of quality milk. The tree is resistant to drought and leguminous compared to nappier grass often used as it will require adequate irrigation.

Improved farm productivity

Agroforestry will improve farm productivity by decreasing soil erosion, improving soil fertility and protecting the crops from strong winds and pests. These beneficial roles of trees will help increase crop yields.

Environmental sustainability

Agroforestry reduces flooding and soil erosion by increasing the infiltration of rainwater and recharging groundwater. This will reduce the depletion of groundwater used during irrigation. Trees provide a complete ground cover protect the soil from soil erosion and extreme temperatures. It contributes to carbon emissions reduction caused by deforestation.

Income diversification

Farmers can get another source of income from incorporating trees in their farms.

Products such as latex rubber gloves, sponges, wine corks, chewing gum, car wax, hair dye and chocolate are made from trees.
