Which Drought Affects Crop Production?

Drought can stunt the growth of crops, resulting in a decline in the size and quality of produce. Consumers may expect to see higher prices for local food as farmers cope with lower yields and higher expenses. Limited water availability for washing produce may lead to sanitation and health issues for consumers.

What is the impact of drought on food production?

Declining agricultural production could lead to shortages of some food items like maize, wheat and some protein sources such as meat and eggs. This could, in turn, force South Africa to import more. Thirdly, a shortage of local produce could push up prices.

How does drought reduce crop yields?

Under drought conditions, crops close their stomata to limit evaporative water loss, thus reducing carbon uptake by photosynthesis and decreasing yields. Globally, it is estimated that a cereal (maize, rice and wheat) loss of 1820 million Mg has been caused by droughts during the past four decades (Lesk et al., 2016).
