Climate change in Africa is an increasingly serious threat as Africa is among the most vulnerable continents to the effects of climate change. Some sources even classify Africa as "the most vulnerable continent on Earth". This vulnerability is driven by a range of factors that include weak adaptive capacity, high dependence on ecosystem goods for livelihoods, and less developed agricultural production systems. The risks of climate change on agricultural production, food security, water resources and ecosystem services will likely have increasingly severe consequences on lives and sustainable development prospects in Africa. With high confidence, it was projected by the IPCC in 2007 that in many African countries and regions, agricultural production and food security would probably be severely compromised by climate change and climate variability. Managing this risk requires an integration of mitigation and adaptation strategies in the management of ecosystem goods and services, and the agriculture production systems in Africa.
Climate change is causing Egypt’s already hot and arid climate to experience environmental stresses including extreme temperatures, droughts, floods, and sea level rise. These extreme conditions will have significant impacts on the lives of Egyptians resulting in food insecurity, water scarcity, and economic destabilization.
In Iraq, climate change has led to environmental impacts such as increasing temperatures, decreasing precipitation, land degradation, and water scarcity. Climate change poses numerous risks to human health, livelihoods, political stability, and the sustainable development of the nation. The combination of ecological factors, conflict, weak governance, and an impeded capacity to mitigate climate change, has made Iraq uniquely at risk to the negative effects of climate change, with the UN ranking them the 5th most vulnerable country to climate change. Rising temperatures, intensified droughts, declining precipitation, desertification, salinization, and the increasing prevalence of dust storms are challenges Iraq faces due in to the negative impacts of climate change. National and regional political instability and conflict have made it difficult to mitigate the effects of climate change, address transnational water management, and develop sustainably. Climate change has negatively impacted Iraq's population through loss of economic opportunity, food insecurity, water scarcity, and displacement.
Climate change in Tanzania is affecting the natural environment and residents of Tanzania. Temperatures in Tanzania are rising with a higher likelihood of intense rainfall events and of dry spells.
Climate change in Somalia refers to changes in the climate in Somalia and the subsequent response, adaption and mitigation strategies of the country.
Climate change in Senegal will have wide reaching impacts on many aspects of life in Senegal. Climate change will cause an increase in average temperatures over west Africa by between 1.5 and 4 °C by mid-century, relative to 1986–2005. Projections of rainfall indicate an overall decrease in rainfall and an increase in intense mega-storm events over the Sahel. The sea level is expected to rise faster in West Africa than the global average. Although Senegal is currently not a major contributor to global greenhouse gas emissions, it is one of the countries most vulnerable to climate change.
South Sudan is one of the five most vulnerable countries to climate change in the world. The country is facing the impacts of climate change, including droughts and flooding, which have indirect and interlinked implications for peace and security. Mean annual temperatures across South Sudan have increased by more than 0.4°C every decade in the past 30 years and are projected to increase between 1°C and 1.5°C by 2060, creating a warmer and drier climate. In the northeast, rainfall has decreased by 15–20%, but other regions experienced more frequent and severe floods.
Climate change is posing an increasing threat to global socio-economic development and environmental sustainability. Developing countries with low adaptive capacity and high vulnerability to the phenomenon are disproportionately affected. Climate change in Kenya is increasingly impacting the lives of Kenya's citizens and the environment. Climate Change has led to more frequent extreme weather events like droughts which last longer than usual, irregular and unpredictable rainfall, flooding and increasing temperatures.
Iran is among the most vulnerable to climate change in the Middle East and North Africa (MENA). Iran contributes to about 1.8% of global greenhouse gas emissions (GHG), and is ranked 8th in greenhouse gas emissions (GHG) world wide and is ranked first in the MENA region due to its reliance on oil and natural gas. Climate change has led to reduced precipitation as well as increased temperatures, with Iran holding the hottest temperature recorded in Asia.
The amount of greenhouse gas emissions from agriculture is significant: The agriculture, forestry and land use sector contribute between 13% and 21% of global greenhouse gas emissions. Agriculture contributes towards climate change through direct greenhouse gas emissions and by the conversion of non-agricultural land such as forests into agricultural land. Emissions of nitrous oxide and methane make up over half of total greenhouse gas emission from agriculture. Animal husbandry is a major source of greenhouse gas emissions.
Climate change and agriculture are complexly related processes. In the United States, agriculture is the second largest emitter of greenhouse gases (GHG), behind the energy sector. Direct GHG emissions from the agricultural sector account for 8.4% of total U.S. emissions, but the loss of soil organic carbon through soil erosion indirectly contributes to emissions as well. While agriculture plays a role in propelling climate change, it is also affected by the direct and secondary consequences of climate change. USDA research indicates that these climatic changes will lead to a decline in yield and nutrient density in key crops, as well as decreased livestock productivity. Climate change poses unprecedented challenges to U.S. agriculture due to the sensitivity of agricultural productivity and costs to changing climate conditions. Rural communities dependent on agriculture are particularly vulnerable to climate change threats.
Climate change in the Middle East and North Africa (MENA) refers to changes in the climate of the MENA region and the subsequent response, adaption and mitigation strategies of countries in the region. In 2018, the MENA region emitted 3.2 billion tonnes of carbon dioxide and produced 8.7% of global greenhouse gas emissions (GHG) despite making up only 6% of the global population. These emissions are mostly from the energy sector, an integral component of many Middle Eastern and North African economies due to the extensive oil and natural gas reserves that are found within the region. The region of Middle East is one of the most vulnerable to climate change. The impacts include increase in drought conditions, aridity, heatwaves and sea level rise.
Climate change in South Africa is leading to increased temperatures and rainfall variability. Evidence shows that extreme weather events are becoming more prominent due to climate change. This is a critical concern for South Africans as climate change will affect the overall status and wellbeing of the country, for example with regards to water resources. Just like many other parts of the world, climate research showed that the real challenge in South Africa was more related to environmental issues rather than developmental ones. The most severe effect will be targeting the water supply, which has huge effects on the agriculture sector. 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.
Climate change in Nigeria is evident from temperature increase, rainfall variability. It is also reflected in drought, desertification, rising sea levels, erosion, floods, thunderstorms, bush fires, landslides, land degradation, more frequent, extreme weather conditions and loss of biodiversity. All of which continues to negatively affect human and animal life and also the ecosystems in Nigeria. Although, depending on the location, regions experience climate change with significant higher temperatures during the dry seasons while rainfalls during rainy seasons help keep the temperature at milder levels. The effects of climate change prompted the World Meteorological Organization, in its 40th Executive Council 1988, to establish a new international scientific assessment panel to be called the International Panel on Climate Change (IPCC). The 2007 IPCC's fourth and final Assessment Report (AR4) revealed that there is a considerable threat of climate change that requires urgent global attention. The report further attributed the present global warming to largely anthropogenic practices. The Earth is almost at a point of no return as it faces environmental threats which include atmospheric and marine pollution, global warming, ozone depletion, the dangers of pollution by nuclear and other hazardous substances, and the extinction of various wildlife species.
Israel, like many other countries in the Middle East and North Africa, experience adverse effects from climate change. Annual and mean temperatures are increasing in Israel, with mean temperature expected to increase between 1.6 and 1.8 °C by 2100. There is a reduction in annual precipitation and delayed winter rains. Israel is already experiencing droughts and water shortages. Heatwaves are other natural hazards expected to increase with climate change.
Climate change impacts are occurring in Zimbabwe, even though the country's contribution to greenhouse gas emissions is very minimal.
Lesotho is a country in southern Africa that is already experiencing the negative effects of climate change, including increased frequency of extreme weather, such as droughts, increased rates of soil erosion and desertification, and reduced soil fertility. Lesotho is a landlocked country that is particularly vulnerable to the negative impacts of climate variability and changes in water and food security, as well as adverse conditions to health, human settlements, and the energy sector.
Eswatini also known as Swaziland, a landlocked nation located in Southern Africa, is characterized by a subtropical climate that features wet and hot summers as well as cold and dry winters. The country has expressed concern regarding the impact of climate change on its existing social challenges, which include but are not limited to issues such as poverty, a high prevalence of HIV, and food insecurity. Furthermore, it is anticipated that climate change will significantly impede the country's development progress, by Vision 2022.
Malawi is a land-locked country in southeastern Africa situated along the southernmost arm of the East African Rift-Valley System between latitudes 9°22’ and 17°03’ south of the equator, and longitudes 33°40’ and 35°55’ east of the Greenwich meridian. It shares borders with Tanzania in the north and northeast, Mozambique in the southwest, south, and east, and Zambia in the west. Malawi is highly vulnerable to the effects of climate change as the vast majority of Malawians rely on small-scale, rain-fed agriculture, making them highly dependent on weather patterns. Climate change increasingly exacerbates droughts, flooding, and inconsistent rainfall—contributing to food insecurity and threatening to derail progress toward Malawi’s goal of self-reliance.
Eritrea is a small coastal nation situated along the Red Sea in the Horn of Africa. It shares borders with Sudan, Ethiopia, and Djibouti. The country spans a total land area of 124,300 square kilometers and boasts a coastline extending 1,900 kilometers. Eritrea's territorial waters in the Red Sea zone comprise approximately 120,000 square kilometers. It possesses diverse eco-geographic regions that provide unique habitats for both marine and terrestrial flora and fauna. Eritrea is one of the most vulnerable countries of the world to the adverse effects of climate change and increased climate variability has already been evidenced in the country.
