Food security

• Human-induced climate change made the severe 2015–2017 drought three to six times more likely.
• Our new report on Climate Change Impacts in South Africa has found that as Earth warms, people living in South Africa will face reduced incomes, less food and water security and a higher cost of living.
• Our findings, based on a synthesis and review of existing research on climate change, are that climate change and socioeconomic risks threaten to bring about a huge change to this status.
• Combating the impacts of climate change in South Africa requires adaptive measures, such as changing the way we farm, coordination by the government and international commitment to reduce emissions.

Heatwaves

• Farm workers will be exposed to more extreme temperatures working outside and others will suffer from heat stress in their living and working environment.
• Here's how

  Extreme weather threatens the plants and animals that attract tourism, and directly damages infrastructure at nature reserves, adventure destinations and parks.

• Rising temperatures are projected to reduce visitor numbers to South Africa’s national parks by 4% by 2050, affecting the Kruger National Park most.

An agricultural crisis

• Smallholder farms are often located in areas with less fertile soils or limited infrastructure, leaving these farmers more vulnerable to climate change.
• Arable land suitable for growing crops is concentrated in just 12% of South Africa’s land area.
• Therefore, any extreme event that reduces production – such as drought – can be expected to reduce job security and income for farming households and agricultural workers.

Water

• Drought and floods damage transport links, public buildings, and water and energy infrastructure, and challenge the provision of basic services.
• During the water crisis that followed the 2015–2017 drought, for example, reservoirs serving 3.7 million people around Cape Town dropped to 20% of capacity, leading the government to impose water restrictions.

An increase in gender-based violence

• These gender inequalities include a high incidence of gender-based violence and a higher likelihood of poverty among women.
• Research in other parts of the world has also linked rising temperatures with an increase in gender-based violence.

Solutions

Much of the country’s economic future hinges on the speed with which investments in renewable energy can replace coal and provide affordable and reliable electricity. Slowing down climate change will take a huge global effort and progress has been limited. The only alternative is to be prepared and adapt to the projected changes.
