UN Climate Change News, 27 October 2020 – Increasing temperatures and sea levels, changing precipitation patterns and more extreme weather are threatening human health and safety, food and water security and socio-economic development in Africa, according to a new report devoted exclusively to the continent. Climate change is straining livelihoods across broad swaths of Africa, intensifying instability in multifaceted ways. A robust and coherent global pattern is discernible of the impacts of climate change on crop productivity that could have consequences for food availability. Guy Midgley. However, quantitative studies on the potential impact of climate change on fisheries and its subsequent impact on human well-being in West Africa are still scarce. The Regional Impacts of Climate Change: An Assessment of Vulnerability. The second phase will use an integrated assessment approach and It tends to most affect the poorest countries that have the lowest carbon emissions. Climate change poses a significant threat to smallholder farmers and threatens to undermine global progress toward poverty alleviation, food security, and sustainable development [1, 2].Globally, there are an estimated 475 million smallholder farmers cultivating less than 2 ha of land [], many of whom are poor, experience food insecurity, and live in highly precarious conditions [4, 5]. Climate change impact mostly felt in Africa. Taylor 549 Ch H3 Environmental Impacts of Irrigation on Water Resources in South Africa and Climate Change: Projected Impacts of Climate Change on Drought Patterns Over East Africa Gebremedhin Gebremeskel Haile1,2,3, Qiuhong Tang1,2, Seyed‐Mohammad Hosseini‐Moghari1, Xingcai Liu1, T.

The simulations suggest that using forestation to mitigate the impacts of global warming may produce unintended climate impacts over some areas in Southern Africa. Climate change is especially a threat to the global goals of sustainable development and eliminating poverty around the world.. Because many of the agricultural systems in developing countries are already under stress today due to land and water resource degradation, climate change and its associated extreme weather … Climate change in Africa is an increasingly serious threat for Africans as Africa is among the most vulnerable continents to climate change. Development Under Climate Change • Analytical work completed for: –Zambeze River Valley –Vietnam –Carbon tax in collaboration with NT • Current collaborative process in South Africa to consider climate change impacts and potential adaptation strategies. Climatic impacts such as drought and desertification have caused the depletion of resources in Nigeria’s northern region. Maize, in particular, contributes the greatest calories Introduction. AR6 Climate Change 2021: Impacts, Adaptation and Vulnerability The Working Group II contribution to the Sixth Assessment Report. READ PAPER. 1. Keywords Climate change Impacts Vulnerability Sub-Saharan Africa Introduction Africa has been identified as one of the parts of the world most vulnerable to the impacts of climate change (IPCC 2014; Niang et al. Africa has the world’s lowest CO 2 emissions ().Climate change is now recognized as an equity issue because the world’s poorest people, those who contributed least to the atmospheric buildup of greenhouse gases, are the least equipped to deal with the negative impacts of climate change. Climate change issues discussed here raise the need for state support for more research and education in impacts of climate change on human settlements in Africa. From a human perspective, the rapid climate change and accelerating biodiversity loss risks human security (e.g. Climate change, rising populations and agriculture mean one of Africa’s largest water sources is now a tenth of the size it was in the 1960s. The Africa Adaptation Acceleration Programme is built to address the impacts of Covid-19, climate change and the continent’s worst recession in 25 years, which is … Human beings originated in Africa about 100,000 years ago and have developed societies that have contributed to climate change, which risks making the globe uninhabitable for our species and many others. Despite being one of the continents with the least greenhouse gas emissions, no continent is being struck as severely by climate change (CC) as Africa. Africa: Climate Change Impacts Introduction. It summarised key climate change impacts and potential response options identified for primary sectors, namely water, agriculture and forestry, human health, marine fisheries, and biodiversity. Schulze & M.A. 1999. The WHO study only looked at a partial list of health impacts. Climate change poses a threat to economic growth and long-term prosperity of many countries around the world. Aggregated results, however, conceal variability, that is, in other areas yields will increase and areas where subsistence agriculture is the norm, yields will reduce [ 39 ]. This technical report was commissioned by African Ministerial Conference on the Environment (AMCEN) on inform policymakers of the shortcomings and opportunities for adaptation to climate change in Africa.The results demonstrate how delaying action now will result in exponential costs down the road. Despite emitting the lowest amount of carbon per capita in the world, Africa suffers the worst of the impacts of climate change, including droughts and floods, locust and pest invasions, according to the head of the African Development Bank Group (AfDB). Africa is one of the continents that is most highly affected by climate change for two reasons: its geographical characteristics of having a majority of land lying across the warming tropics, and the limited human, social, and economic capacity that African countries have to adapt to the impacts of climate change (Leal Filho et al., 2015). Investigation of the pressing impacts of climate change on drought is vital for sustainable societal and ecosystem functioning. There is no doubt that climate change has affected a lot of nature/environment cycles in Vietnam. 28-May-2020. South Africa is undertaking significant actions to respond to climate change risks and impacts. Biodiversity and Climate Change, Convention on Biological Diversity, December, 2009 . Adaptation policies aimed at enhancing resilience to a changing climate, such as investing in disaster-proof infrastructure and early warning systems, risk sharing through financial markets, and the development of social safety nets, can limit the impact of weather-related shocks and help the economy recover faster, according to the report. But climate change is not just about droughts, the report explains: 3, July, pp. In order to jointly address the security risks of climate change in Africa from a development and security Africa will be hardest hit by climate change, but has contributed the least to causing that change. experiencing climate change and will, without a doubt, continue to do so in the future. 37 Full PDFs related to this paper. Persons living in poverty face compounding vulnerabilities to climate change impacts because they lack the resources to quickly recover from its effects. Norvergence with the help of the United Nations Framework Convention on Climate Change has predicted some possible effects of climate change as discussed below: Water resources. Climate change seriously threatens sustainable development, poverty reduction and the achieve-ment of the Millennium Development Goals (MDGs), particularly in Africa. (2011). Climate change is a serious threat to crop productivity in regions that are already food insecure. The initiative called Raising Risk Awareness will involve a team of scientists who will examine whether climate change has contributed to extreme weather events such as droughts, floods and heatwaves in East Africa … Because of the lack of economic, development, and institutional capacity, African countries are likely among the most vulnerable to the impacts of climate change (IPCC, 2001). The growing impact of climate change has major implications for South Africa, especially for the numerous vulnerable groups in the country. According to the 5th IPCC Assessment Report Africa is particularly vulnerable to climate change. Climate change may have significant impacts in the east African highland region in the future, where the population at risk is large. WIREs Climate Change Climate change impacts in South Africa that integrates these two sectors is a study of the water-stressed Sandveld in the Western Cape region. The meta-analysis makes use of studies that investigated and reported percentage changes in maize yield owing to climate change in South Africa. "Future African Water Resources: Interactions between Soil Degradation and Global Warming," Climatic Change, Vol. Adaptation measures for especially maize, common beans, Arabica coffee, banana and finger millet are urgently needed in Africa to curb future negative climate impacts. Many projections of the impact of climate change on the crop, livestock and fishery production sectors of African agriculture are reported in the literature. What's the future for Africa's livestock herders as our climate changes, becomes less predictable, heats up? A doubling of irrigation development, on the other hand, will not be sufficient to reverse adverse impacts from climate change in the country. Cambridge University Press. • Crop net revenues will likely fall by as much as 90% by 2100, with small-scale farms being the most affected. We assessed the projected impacts of climate change on the yield of eight major crops in Africa and South Asia using a systematic review and meta-analysis of data in 52 original publications from an initial screen of 1144 studies. And the poorest regions of the world – Sub-Saharan Africa and South Asia – will be hit the hardest. Climate Change in the United States: Benefits of Global Action. It has been prognosed that land temperatures over Africa will rise faster than the global average, particularly in the more arid regions such as Madagascar. This study therefore investigates the impacts of global warming on maize production in South Africa using a meta-analysis (for physical impacts) and the Ricardian analysis (for economic impacts). This paper uses a comprehensive climate change scenario (CCC) based on ensembles of 17 GCMs selected based on their relative performance regarding past predictions of temperature and precipitation at the level of 2o x 2o grid cells, generated by a recently developed entropy-based downscaling model. While some The impacts of climate change are predicted to affect the livelihoods of most people in developing countries and most especially in Africa in many ways. The magnitude of how much the drought will change and the way how droughts would affect society and the environment are inadequately addressed over East Africa. Climate change is expected to exacerbate these trends. Find out more. The African continent has been identified as particularly vulnerable to the changing climate due to its envisaged low adaptive capacity and vulnerability (Callaway, 2004).The southern African region is regarded as one of the most vulnerable regions in Africa (IPCC, 2007b).Within the climate change matrix, water resources are at the epicentre of projected climate change impacts. One region of the world where the effects of climate change are being felt particularly hard is Africa. Africa is often described as the continent most at risk to the negative effects of climate change, both because of the expected change itself and because of the perceived lack of capacity of Africans and their governments to adapt. Overall, negative impacts of climate change on rice yields in Africa are shown in all scenarios if farmers stay with current varieties. Idah Pswarayi-Riddihough, Sector Manager for Environment, World Bank The stability of whole food systems may be at risk under climate change because of short-term variability in supply. Impacts of climate change on agriculture in developing countries. WIREs Climate Change Climate change impacts in South Africa BOX 1 LONG TERM ADAPTATION SCENARIOS (LTAS) PROJECT South Africa’s 2011 national policy position on climate change emphasizes that socio-economic risks resulting from a range of emission scenar-ios need to be better understood and quanti-fied in order to inform planning and practice.3 For Africa, previous work on climate change impacts indicates that maize (-5 %), sorghum (-14.5 %) and millet (-9.6 %) yields are set to decline significantly, whereas rice and cassava yields are projected to not be significantly impacted during the 21st century (Knox et al., 2012). 42, No. SA-TIED Dialogues – Research into Policy. Climate Change 2001: Impacts, Adaptation and Vulnerability. Cambridge University Press. Feddema, Johannes J. By 2020, between 75 and 250 million people are predicted to be exposed to increased water stress due to climate change. experiencing climate change and will, without a doubt, continue to do so in the future. The World Bank’s recent report, Turn Down the Heat: 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. For South Africa to adapt to the adverse consequences of global climate change, it would require yield improvements of more than 20 percent over baseline investments in agricultural research and development. Climate change is inherently unfair. [NAIROBI] An initiative has been formed to help African and Asian societies understand climate change-related impacts such as extreme weather events and prepare for future ones. The role of market adaptation during massive levels of catastrophe like climate change should not be underestimated as they can play a big role.

This lesson plan provides an introduction to climate change, causes and impacts of climate change globally, climate change risk profile for South Africa that includes climate impacts on major sectors of the country such as agriculture, water resources, human health, ecosystems, energy, infrastructure, and disasters. Women labourers often experience additional duties as caregivers and as well as from societal responses to climate change after extreme weather events (eg, male migration). Th e paper concludes with recommenda-tions and a suggested way forward. It will lead to increased temperatures, rising sea levels, altered precipitation patterns and increased frequencies of extreme weather events such as floods and droughts. But the report, Shock Waves: Managing the Impacts of Climate Change on Poverty, also points to a way out. 4.5 Synthesis. Schulze 540 Ch H2 Net Irrigation Demands in South Africa and Climate Change R.E. Of course, Cameroon can, and will, play their role in … The study explored the impacts of climate change on water resources, and the community-based adaptation practices adopted to ensure water security in a rural community in Limpopo Province, South Africa.,The study was conducted in Limpopo Province, South Africa. These impacts extend well beyond an increase in temperature, affecting ecosystems and communities in the United States and around the world. 16 Impacts of Climate Change 13. In terms of climate change and natural disasters, there is a general agreement that poorer countries suffer more. Any attempt to understand the impacts of climate change on Africa is fraught with diffi culties. Climate change impacts have Africa is often described as the continent most at risk to the negative effects of climate change, both because of the expected change itself and because of the perceived lack of capacity of Africans and their governments to adapt. Global Affairs Canada has awarded funding to PEP for a new research initiative on “Climate change in Africa: Impacts and responses for women and girls”. • By 2080, arid and semi-arid land in Africa could increase by 5-8% (60-90 million hectares). The micro-site details FCFA’s key climate science advances in; delivering new model developments, understanding past and future climate extremes, understanding the processes that influence Africa’s climate, narrowing global model uncertainty over Africa and predicting the impacts of climate change in Africa. Africa is projected to experience increasing climate hazards for the remainder of the 21st century, which are likely to pose a challenge to hydropower generation in Africa. The Changing Climate of West Africa . Working Paper (20-10) by Johannes Emmerling, Soheil Shayegh, and Shouro Dasgupta — … A short summary of this paper.

Threats to human healthIn their discussion of climate change impacts on health services, Marlies Craig and Brian Sharp (Medical Research Council, Durban, South Africa) emphasized the effects of two major parasitic diseases in South Africa, malaria and schistosomiasis. Africa, which contributes only 3.6% of the total global emissions, is disproportionately affected by the impacts of climate change. Africa is not an exception, considering the actual and potential impacts of climate change and climate variability that will threaten its vulnerable sectors and human populations. In this article, we highlight 10 impacts of climate change in East Africa that are not well known to many people. And now South Africa also has to respond to the impacts of climate change by reducing emissions and helping poor people adapt to the changing climate. Climate change is expected to have significant impacts on natural resources, the world economy and human health. Evidence shows that extreme weather events are becoming more prominent due to climate change. Climate change can disrupt food availability, reduce access to food, and affect food quality. Climate-induced effects are more consistent with the observed changes over a few regions of Africa and South America. Literatures indicate climate components like temperature, precipitation, CO2 concentration and extreme climate events have an effect on food security components. Climate change in South Africa is leading to increased temperatures and rainfall variability. Already experi-encing temperature increases of approximately 0.7°C over much of the continent, and with predictions that temperatures will rise further, Africa is facing a wide range of impacts… Feature: What Climate Change Means for Africa, Asia and the Coastal Poor Executive Summary : Turn Down the Heat: Climate Extremes, Regional Impacts, and … Introduction.
