Climate change will impact agriculture in South Africa (trellised vines in Stellenbosch)

Climate change in South Africa is leading to increased temperatures and rainfall variability. Evidence shows that

environmental issues rather than developmental ones.[2] The most severe effect will be targeting the water supply, which has huge effects on the agriculture sector.[3] Speedy environmental changes are resulting in clear effects on the community and environmental level in different ways and aspects, starting with air quality, to temperature and weather patterns, reaching out to food security and disease burden.[4]

The various effects of climate change on rural communities are expected to include: drought, depletion of water resources and biodiversity, soil erosion, decreased subsistence economies and cessation of cultural activities.[5]

South Africa contributes considerable CO
2

emissions, being the 14th largest emitter of CO
2.[3] Above the global average, South Africa had 9.5 tons of CO
2 emissions per capita in 2015.[3] This is in large part due to its energy system relying heavily on coal and oil.[3] As part of its international commitments, South Africa has pledged to peak emissions between 2020 and 2025.[3]

Greenhouse gas emissions

South Africa is the world's 14th largest emitter of greenhouse gases.[3]

Energy sector

This section is an excerpt from Energy in South Africa.[edit]

South African total primary energy supply as of 2018[6]

  Coal (65%)
  Crude Oil (18%)
  Renewables & Waste (11%)
  Gas (3%)
  Nuclear (2%)
  Geothermal (1%)

South Africa has a large energy sector, being the

TWh of electricity in 2018.[7] The vast majority of South Africa's electricity was produced from coal, with the fuel responsible for 88% of production in 2017.[8]
South Africa is the 7th largest coal producer in the world.[8] As of July 2018, South Africa had a coal power generation capacity of 39 gigawatts (GW).[8] South Africa is the world's 14th largest emitter of greenhouse gases.[8] South Africa is planning to shift away from coal in the electricity sector and the country produces the most solar and wind energy by terawatt-hours in Africa.[9] The country aims to decommission 34 GW of coal-fired power capacity by 2050.[8]

It also aims to build at least 20 GW of renewable power generation capacity by 2030.[10] South Africa aims to generate 77,834 megawatts (MW) of electricity by 2030, with new capacity coming significantly from renewable sources to meet emission reduction targets.[11][12] Through its goals stated in the Integrated Resource Plan, it announced the Renewable Energy Independent Power Producer Procurement Programme, which aims to increase renewable power generation through private sector investment.[13][6]

Renewable energy

transportation, and rural energy services.[15] The energy sector in South Africa is an important component of global energy regimes due to the country's innovation and advances in renewable energy.[16] South Africa's greenhouse gas (GHG) emissions is ranked as moderate and its per capita emission rate is higher than the global average. Energy demand within the country is expected to rise steadily and double by 2025.[16]

Transportation

The transport sector in South Africa contributes 10.8% of total Greenhouse Gas (GHG) Emissions in the country. Apart from the direct emissions, indirect emissions through the production and transportation of fuels also provide substantial emissions.[17][3] Road transport, in particular, contributes approximately three quarters to total transport emissions.[18]

Impacts on the natural environment

Temperature and weather changes

There has been different confirmations over climate change effects in

droughts.[3]

Africa is currently and prospectively suffering from significant heat waves based on the nature of the continent amid the current environmental crisis.[19]

Impacts on people

Economic impacts

Agriculture

Main article: Agriculture in South Africa

The main challenge that faces any nation because of climate change is its direct effect on food security. In this sense, Africa is listed as the most vulnerable continent to climate changes.[20] In Ethiopia for example, food production faces a lot of challenges because of climate change. It is noted that there is an increase in the annual production losses to climate changes from year to year.[21]

rainfall will result in limited water resources and changing soil moisture, leading to decreased cropland productivity.[23]

Some predictions show surface water supply could decrease by 60% by the year 2070 in parts of the

natural resources.[25]

South Africa's field crops, has also experienced negative effects due to climate change. The estimated value of the loss, which takes into consideration scenarios with and without the carbon dioxide fertilization effect,[26] ranges between tens and hundreds of millions of rands.[27]

Tourism

Further information: Tourism in South Africa

South Africa has an important tourism aspect to look at and give considerable attention to when considering climate change impact. This is a sensitive sector to mention but its importance lies in its vulnerability to climate change that is growing lately.[28] Challenges exceed the fact that there is a need to pave the way for more tourists to come. South Africa's main concern extends to develop poverty mitigation plans resulted from climate change in South Africa.[29] Tourism urged policy makers in Africa to improve job opportunities, economical growth and support different industries. There are different critical challenges facing Tourism sector in South Africa and that was mainly a result of Climate Change effects.[30] In this regard, it is important to notice that the national government in South Africa started to implement new tourism and climate based policies to over come the challenges.[31] It is significant to mention that the general climate in South Africa suffers from varied conditions and changes/ These variations target summer and winter rainfall regions, subtropical areas, and both humid and arid regions.[32]

Health impacts

There is evidence that climate change will have negative impacts on public health in South Africa, especially due to the high proportion of vulnerable people.[33] There is already a high burden of disease in South Africa linked to environmental stressors and climate change will exacerbate many of these social and environmental issues.[34] Climate change is projected to threaten public health through increased heat stress, rises in vector-borne diseases and infectious diseases, worsening extreme weather events, a decline in food security, and increased mental health stress.[35] A 2019 survey of literature on adaptation and public health, found that "the volume and quality of research is disappointing, and disproportionate to the threat posed by climate change in South Africa.".[36]

Mitigation

COP15
.

The South African government has committed to a peak of CO
2 emissions between 2020 and 2025. South Africa has agreed to working with other signatories of the Paris Agreement to keep temperature increases below 2 °C.[37] However, independent observers have called the current actions by the government insufficient.[3] In part, this failure to act is related to the government ownership of Eskom, which is responsible for much of the coal operation in the country.[3] Similarly, the economy is one of the most energy-intensive in the world although it has not been setting mitigation targets for industry.[3] Catalysing finance and investment to transition to a low-carbon economy and society is a major challenge for South Africa.[37]

Like all countries which are party to the

UNFCCC at least biennially from 2024 at the latest.[38]

The European Investment Bank Global and the Development Bank of Southern Africa have agreed to a €200 million loan to support a new targeted financing initiative aimed at unlocking €400 million for private sector renewable energy investment in South Africa.[39]

Adaptation

The South African government drafted its National Climate Change Adaptation Strategy (NCCAS) in 2019. This strategy presents a vision for adapting to climate change and increasing resilience in the country. This strategy also and outlines priority areas for achieving this vision, which includes water resources, agriculture and commercial forestry, health, biodiversity and ecosystems, human settlements, and disaster risk reduction.[1] This strategy was also developed to act on the country's commitment to its obligations in the Paris Agreement under the United Nations Framework Convention on Climate Change (UNFCCC).

South Africa is in the progress of finalizing its national climate change adaptation strategy. "The National Adaptation strategy acts as a common reference point for climate change adaptation efforts in South Africa, and it provides a platform upon which national climate change adaptation objectives for the country can be articulated so as to provide overarching guidance to all sectors of the economy[40]"[needs update]

Society and culture

Activism

Global Day of Action protests in Durban, 2011

Amid the 2011 UN Climate Change Conference (COP17) held in Durban, demonstrations and protests were organized to raise concerns on climate change issues. A march gathering 12,000 people urged the delegates at COP17 to take urgent climate action.[41] Protesters also made an intrusion into the conference venue at the time when the negotiations were at the deadlock.[42]

Public awareness

Popular awareness of these potential impacts increased with the

2018–20 Southern Africa drought and subsequent Cape Town water crisis.[21]
