How climate change has affected agricultural production in south africa


Climate change effects on irrigation demand and crop yields in South Africa. The demand for irrigation is likely to increase in South Africa as a result of increased temperatures and evaporation rates. Rain-fed agricultural crops are likely to experience a decline in average annual yields.

How is climate change affecting the agricultural sector in South Africa?

Agriculture in South Africa faces a variety of risks associated with climate change, such as changes in rain patterns, increased evaporation rates, higher temperatures, increased pests and diseases and changes in diseases and pest distribution ranges, reduced yields and spatial shift in optimum growing regions.

How does climate change affect agricultural production?

Negative impacts of global warming include reduced crop quantity and quality due to the reduced growth period following high levels of temperature rise; reduced sugar content, bad coloration, and reduced storage stability in fruits; increase of weeds, blights, and harmful insects in agricultural crops; reduced land …

How does climate change affect agriculture in Africa?

The impact of climate change on African agriculture Projections on yield reduction show a drop of up to 50% and crop revenue is forecast to fall by as much as 90% by 2100. The agriculture sector is also likely to experience periods of prolonged droughts and /or floods during El- Nino events.

How does climate change affect food production in Africa?

According to the IPCC (2007), agricultural productivity will decline from 21% to 9% by 2080 due to climate change in sub-Saharan Africa. The report indicates that rising temperatures in precipitation are likely to reduce the production of stable food by up to 50%.

What are the climatic factors that affect agricultural production?

Climatic factors such as light, water, and rainfall, temperature, air, relative humidity and wind also affect farming in various ways. Just like other abiotic elements of environmental factors such as soil and topography, they influence how crops grow and develop.

How does climate change affect agriculture essay?

Climate change is affecting agriculture by interfering with the efficiency of crop production. Agriculture is facing droughts, flooding, sea level elevations, natural disasters, and health hazards for employees. All of these exponents lead to crop failure that creates famines and food prices to rise.

What is the impact of climate change on South Africa?

Climate change poses a significant threat to South Africa’s water resources, food security, health, infrastructure and ecosystem services and biodiversity. In a country where many people are poor and where levels of inequality are high, these effects of climate change are critical challenges to development.

How will climate change affect food production?

In short, climate change is putting food production at risk. Yield growth for wheat, maize, and other crops has been declining in many countries due to extreme heat, severe weather, and droughts. By some estimates, in the absence of effective adaptation, global yields could decline by up to 30 percent by 2050.

Why is African agriculture the most vulnerable to the impact of climate change?

Climate change cause shifts in growing seasons, lower agricultural yields as a result of variability in rainfall and higher temperature patterns and reduce local food availability. With decrease production at the continental level, Africa will be dependent of food imports and aid.

What are the threats to agricultural production in Africa?

These threats included floods, theft of crops, scarcity of land and increase in price of agricultural inputs such as seeds, manure and pesticides.

What are the 5 effects of climate change?

Effects of Climate ChangeHotter temperatures. As greenhouse gas concentrations rise, so does the global surface temperature. … More severe storms. … Increased drought. … A warming, rising ocean. … Loss of species. … Not enough food. … More health risks. … Poverty and displacement.

How does climate change affect Africa?

Health impacts Increases in temperature and changes in rainfall patterns also significantly affect population health across Africa. Warmer temperatures and higher rainfall increase habitat suitability for biting insects and the transmission of vector-borne diseases such as dengue fever, malaria and yellow fever.

Climate Change Is Highly Likely to Negatively Affect The Economy

  • Climate change is highly likely to negatively affect the South African economy, primarily because of its large negative impacts on agricultural crop yields. Studies have shown that field crops in South Africa are highly likely to be sensitive to even marginal changes in temperature, as crops are already close to tolerance levels. Temperature increa…

Agriculture Directly Affected Due to Large Dependence on Rainfed Farming

  • With 80% of crop agriculture dependent on rainfed farming systems, the sector is highly vulnerable to the impacts of climate change. Across most scenarios modelled, climate change negatively affects dryland crop production, raising the price of crops, particularly that of sugarcane, for which there is a large, linked processing sector. Within the model, a shift from dryland to irrigated agriculture takes place where this is an option. The increase in irrigat…

Key Crop Regions Negatively Affected

  • The impacts of climate change vary across water management areas (WMA), with key crop producers often negatively affected. Key crop producers affected by climate change include the Western Cape (WMA 16, 17, 18 and 19), which is a primary producer of high-value crops such as deciduous fruits; the Vaal region (WMA 8, 9 and 10), which is the main producer of summer cereals; and KwaZulu-Natal (WMA 6, 7 and 11), which accounts for al…

Household Welfare and Food Security

  • Despite South Africa being a food-secure nation, there are high levels of food insecurity at the household level in rural areas. Climate change is likely to worsen food insecurity not only at the household level, due to rising prices, but also at the national level, as dependence on imported food is expected to increase as local production declines. Exports are expected to decline as key agricultural exporters, such as the Western Cape, are negatively …
