Thematic Report: Ecosystem Change Due to Climate Change

by Okoth Okoth | 13-09-2020 20:45


Impacts of Climate Change on Agriculture

Unpredicted weather and climate conditions including invasion by swarms of dessert locusts and long heavy rains have cost the Kenyan agricultural sector including sustainable food production. The Food and Agriculture Organization of the United Nations warns of imminent threat to livelihoods in the Horn of Africa if the increasing numbers of dessert locusts is not contained.

The long heavy rains in Kenya since October last year have greatly destroyed crops and affected normal food production patterns. Crops such as tomatoes and potatoes are rotting as a result of too much water while maize crops which require short rains remain stunted.

There is no consolidated data on the crops that have been destroyed by the long rains thereby creating a big gap in risk assessment. The excess soil moisture and flooding in most parts of the country is expected to result in short cycles legumes production and localized maize losses thereby increasing food prices.

Impacts of Long Heavy Rains on the Agriculture
Kenya Agriculture PS assertions that the rains will improve food production in areas which depend on short rains season is short lived and unrealistic because the negative impacts have already been felt in former Nyanza region where maize crops the main staple food in the region are facing localized ponding, stunted growth and a possibility of long harvesting period.

¡°The heavy rains have dealt us a blow, the prolonged rains have eroded the soil and lowered the soil temperatures thereby delaying tassel formation and the leaf stages of our corns. We are expecting reduced yields and huge losses during harvesting.¡± Said Otieno, farmer, Kenya.

The ongoing heavy rains is not only affecting the growth of crops but could probably increase post-harvest losses of various crops, especially the perishable crops due to accessibility problems. Disruption to critical transport infrastructure will further delay the harvesting period thereby increasing quality deterioration of horticultural crops.

¡°The governments should construct dams to contain the floodwaters to be used during dry seasons and empower farmers with adequate information and timely forecasts of weather and climate conditions. This will help us from drier areas to continue with agricultural activities thus improve food security.¡± Said Olila, Bondo, Kenya.

Nonetheless, the rains have replenished grass and other rangeland resources in pastoral areas hence ease of livestock rearing and improved milk productivity. ¡°The ongoing rains is a blessing to us. Our animals can now get enough grass to feed on therefore getting sufficient milk and meat products is no longer a problem for us. The animals can now fetch good market prices due to better body conditions.¡± Said Walala, livestock farmer, Kenya.
