Changing temperature patterns. Water required for food production may become more scarce due to increased crop water use and drought.

The demand for irrigation is likely to increase in South Africa as a result of increased temperatures and evaporation rates.

How does climate change affect agriculture in south africa. Changes in atmospheric carbon dioxide and ground-level. Climate change could increase the prevalence and distribution of vector-borne diseases such as malaria and dengue fever and water-borne diseases such as cholera and dysentery. Richard Washington is a professor of climate science at the School of Geography and the.

Food may become more expensive as climate change mitigation efforts increase energy prices. Hotter temperatures long term. Climate change and agriculture are interrelated processes both of which take place on a global scale with the adverse effects of climate change affecting agriculture both directly and indirectly.

The World Banks recent report Turn Down the Heat. This is particularly the case for maize and wheat which are staple foods. We still dont know for sure what caused this outbreak but some scientists have linked its spread with climate change.

The effects of climate change are becoming increasingly severe in sub-Saharan Africa where millions of people are facing severe food shortages due to drought. Sirte - Climate change will significantly impact on all facets of the continents economic and social well-being but particularly in agriculture and food security says Environment and Water Affairs Minister Buyelwa Sonjica. Africa will be hardest hit by climate change but has contributed the least to causing that change.

Climate change is likely to contribute substantially to food insecurity in the future by increasing food prices and reducing food production. If global temperatures increase by 4 degrees Celsius by the year 2100 maize yields in some African. Projected increases in number of days over 90F between now and 2090 according to two climate change scenarios.

Climate change is expected to make agricultural development in Africa more challenging. Changes in pests and diseases. Rain-fed agricultural crops are likely to experience a decline in average annual yields.

This can take place through changes in average temperatures rainfall and climate extremes eg heat waves. Trends across the different rainfall zones can be linked to changes recorded for large-scale climate systems. A catastrophic combination of drought and communities declining resilience has left an estimated 23 million people facing severe acute food insecurity in Zambia alone according to the International Federation of Red Cross IFRC.

Potential adaptation responses in the agriculture sector range from. Average global temperatures are expected to rise over the coming decades which could lead to desertification and smaller harvests in Sub-Saharan Africa. Changes in South Africas rainfall seasons could.

Soybean and sugarcane are likely to experience no change or an increase in average annual crop yields as precipitation increases. The impacts of climate change on food production agricultural livelihoods and food security in South Africa are significant national policy concerns and are also likely to have implications beyond South Africas borders. Turn Down the Heat finds that an increase of 4 degrees Celsius worldwide would spell increased droughts more frequent flooding and shifts in rainfall in Africa jeopardising the regions food security and economic growth.

Weather patterns are becoming less favorable in many instances increasing the volatility of crop and livestock yields. IPCC projections suggest that warming scenarios risk having devastating effects on crop production and food security. The impact of climate change is already manifesting itself in ever-increasing numbers of extreme events that we are experiencing in Africa such as droughts.

Africa is therefore an exposure and vulnerability hot spot for climate variability and change impacts. Rising average temperatures more extreme heat throughout the year fewer sufficiently cool days during the winter and more frequent cold-season thaws will likely affect farmers in all regions. Agriculture is the backbone of Africas economy and accounts for the majority of livelihoods across the continent.

Climate change worsens existing vulnerabilities and adds to the pressures on the environment and natural resources on which so many South Africans directly rely. Climate Extremes Regional Impacts and the Case for Resilience underscores the urgency of supporting African farmers now so that they can better cope with the potential impacts of a changing climate.
