The effects of climate change in Uganda are increasingly severe, affecting the lives of the country's citizens and its environment. [1] It has led to extreme weather events such as unpredictable, prolonged drought and rainfall. [1] Uganda's climate is mostly tropical with regular rainfall and sunshine patterns. Due to climate change the seasons have changed, with the rainy season becoming more variable in length and droughts more ubiquitous, especially in eastern and northeastern Uganda. [2] Climate trends have the potential to affect development of Uganda, due to the vulnerability of Uganda's diverse environment. [3]
Uganda's greenhouse gas emission rate is very low, with carbon dioxide having never exceeding 150 kg per person per year, and totalling about 5 million tonnes per year. [4] As of 2022, over 90% of Uganda's electricity comes from hydroelectricity, [5] but many rural areas lack electricity and burn wood for cooking. [6] The government has been criticized for causing deforestation. [7]
Since the 1960s, the average temperature in Uganda has increased by 1.3 °C, minimum temperatures have increased by 0.5–1.2 °C, and maximum temperatures have increased by 0.6–0.9 °C. Average temperatures have been observed to be increasing at a rate of 0.28 °C per decade, and daily temperature observations show significantly increasing amounts of hot days and nights every year . [8] Climate change and changes in temperature is also affecting the Rwenzori Mountains, by causing glacier melting, increasing water levels in the Nyamwamba, Mubuku, and Ruimi Rivers. This has led to frequent flooding across the Rwenzori region. [9] From 1906 to 2003, ice fields shrunk from 6.5 sq km to less than 1 sq km, and may completely melt in the next few years. In 2012, forest fires occurred in the Rwenzori region, causing the ice fields to melt, leading to the flooding of the river around the mountain. [9]
In January 2022, intense rain around Mount Muhavura damaged buildings and roads in Kisoro District, [10] especially affecting Nyarusiza, Muramba and Bunagana. [11] Nine people were reported to have lost their lives and thousands of people were displaced or otherwise affected by this disaster. [12] [13]
On 1 March 2010, landslides occurred on the slopes of Mount Elgon, in the Bududa district, that killed 50 people and left thousands displaced. In 2018, there was another landslide on Mount Elgon, that killed 28 people, and left thousands displaced once again. [14] As of 30 September 2021, a total of 20,739 people had been internally displaced. [15] All landslides were caused by unusually prolonged rains. [16]
In Kasese District, there is flooding almost every year, which causes a heavy impact on the lives and livelihood of residents. As a result, many schools and homes are buried or destroyed, leaving many displaced. [20] [21]
On Saturday 30 July 2022 at around 8pm EAT in the evening, there was a down pour of rain that took several hours up to around 7am EAT in the morning of Sunday 31 July 2022 in Mbale district, Sebei region and part of
Teso region. This caused river Nabuyonga and river Namatala to burst the banks causing floods and landslides in Mbale district, Kapsinda Sub-county, Kapchorwa District. This led to a death toll of 24 in Mbale alone as of 2 August 2022, more bodies were recovered on that day. [22] [23] In Mbale, most of the affected areas were Mbale City, Nabuyonga, Nkoma and Namakwekwe in Northern City Division and Namatala in Industrial City Division. [24]
Ugandan water supply and the sanitation sector has made substantial progress in urban areas from the mid-1990s until at least 2006, with substantial increases in coverage. Reforms from 1998 to 2003 included the commercialization and modernization of the National Water and Sewerage Corporation (NWSC) operating in cities and larger towns, as well as decentralization and private sector participation in small towns. [25] Uganda has renewable water resources totalling to 2085 cubic meters per year, which is above the limit recognized internationally of 100 m3/year of water scarcity. Nevertheless, the water sector is developed and only about 0.5% of the total available water is utilized per year. [26]

Uganda has made some progress and improvements in water supply through improving facilities, increasing from 39% availability in 1990 to 48% in 2008, and, in remote and rural areas, from 40% in 1990 to 49% in 2008. This was not the case with the urban areas, which only increased from 35% in 1995 to 38% in 2008. [26]
In 2010, Uganda had 6.93 Mha of tree cover, extending over 29% of its land area. In 2020, it lost 73.6 kha of tree cover, equivalent to 36.0 Mt of CO₂ emissions. From 2001 to 2020, 918 kha of tree cover was lost, equivalent to a 12% decrease in tree cover since 2000 and 413 Mt of CO₂ emissions. From 2001 to 2019, 3.8% of tree cover loss occurred in areas where dominant drivers resulted in deforestation. [27] This has reduced both the ecosystem services the forests provide, including by diminishing wood yield and quality, and the biodiversity they support. 1.4 Mha of land has been burned, as of 2021. This total is normal, compared to the total for previous years, going back to 2001. The most fires recorded in a year was 2005, with 7.3 Mha burnt. [27]
Uganda's economy consists of three major sectors, agriculture, industry, and services, all of which are highly vulnerable to the effects of climate change. [28] Climate change is affecting the agricultural sector by reducing the area suitable for agriculture due to population growth, altering the length of the growing season, reducing yield potential, increasing the frequency and severity of extreme events (in particular droughts and floods), and increasing the incidence of plant diseases. [28]
Climate change damage estimates in the agriculture, water, infrastructure and energy sectors collectively amount to 2–4% of the GDP between 2010 and 2050. With an estimated population of 48,432,863, Uganda is the leading country of organic farming, with an estimate of 231,157 hectares of land used for farming. [29]
Climate change has affected agriculture, which is the most important sector of the economy. [30] Most of the production is from small scale farmers. [31] Average temperatures range between 18 and 30 °C, but it can raise to about 37 °C in some areas. [32]
The Ugandan manufacturing sector is dominated by agro-processing, food and beverages, household products, construction materials and fast-moving consumer goods. Most firms are small and medium enterprises concentrated in Kampala and the Central Region. Most products manufactured in Uganda are aimed at domestic consumption, and exports are limited to the regional markets in East Africa, including Rwanda, Burundi, South Sudan, Democratic Republic of the Congo (DRC), and the regions of Kenya and Tanzania bordering Uganda. [33]
Manufacturing was reported to account for 15.8% of GDP in 2020, according to the World Bank, employing about 6.622% of formal-sector labour. [33]

Climate change is increasing the occurrences of water-borne diseases such as dysentery, cholera, hepatitis E, vector-borne diseases, respiratory diseases, malnutrition-related illnesses, and especially malaria. Uganda's fourth Health Sector Development Plan indicates the importance of developing "early warning systems and dissemination of weather forecasts to help health managers to improve preparedness and response". [35]
A number of government agencies have been tasked with, or have prepared reports, on managing climate resilience, including the National Environmental Management Authority (NEMA), [36] the Ministry of Water and Environment's Climate Change Department, [37] the National Forestry Authority, [38] the Ministry of Lands, Housing & Urban Development, [39] the Ministry of Works and Transport, [40] and the Uganda Wildlife Authority. [41]
The scientific community has been investigating the causes of climate change for decades. After thousands of studies, it came to a consensus, where it is "unequivocal that human influence has warmed the atmosphere, ocean and land since pre-industrial times." This consensus is supported by around 200 scientific organizations worldwide, The dominant role in this climate change has been played by the direct emissions of carbon dioxide from the burning of fossil fuels. Indirect CO2 emissions from land use change, and the emissions of methane, nitrous oxide and other greenhouse gases play major supporting roles.
The Geography of Kenya is diverse, varying amongst its 47 counties. Kenya has a coastline on the Indian Ocean, which contains swamps of East African mangroves. Inland are broad plains and numerous hills. Kenya borders South Sudan to the northwest, Uganda to the west, Somalia to the east, Tanzania to the south, and Ethiopia to the north. Kenya currently faces border disputes with South Sudan over the Ilemi Triangle and with Somalia over Jubbaland where, if the Somalian Government gives it up, it could be a new part of Kenya, which would bring the total land area of Kenya to approximately 692,939 km2.
Environmental issues in Nepal include a number of issues, such as deforestation, climate change, energy and species conservation. Many of these issues have been precipitated by rapid industrialization without major environmental regulation.
African environmental problems are problems caused by the direct and indirect human impacts on the natural environment and affect humans and nearly all forms of life in Africa. Issues include deforestation, soil degradation, air pollution, water pollution, coastal erosion, garbage pollution, climate change, Oil spills, Biodiversity loss, and water scarcity. These issues result in environmental conflict and are connected to broader social struggles for democracy and sovereignty. The scarcity of climate adaptation techniques in Africa makes it the least resilient continent to climate change.
The environment of Indonesia consists of 17,508 islands scattered over both sides of the equator. Indonesia's size, tropical climate, and archipelagic geography, support the world's second highest level of biodiversity after Brazil.
Climate change is having major effects on the Chinese economy, society and the environment. China is the largest emitter of carbon dioxide, through an energy infrastructure heavily focused on coal. Other industries, such as a burgeoning construction industry and industrial manufacturing, contribute heavily to carbon emissions. However, like other developing countries, on a per-capita basis, China's carbon emissions are considerably less than countries like the United States. It has also been noted that higher-income countries have outsourced emissions-intensive industries to China. China is now the world's largest polluter and in 2023 recorded its hottest year on record with an average temperature of 10.7 C. On the basis of cumulative CO2 emissions measured from 1751 through to 2017, China is responsible for 13% globally and about half of the United States' cumulative emissions.
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". Climate change and climate variability will likely reduce agricultural production, food security and water security. As a result, there will be negative consequences on people's lives and sustainable development in Africa.
Globally, Nepal is ranked fourth in terms of vulnerability to climate change. Floods spread across the foothills of the Himalayas and bring landslides, leaving tens of thousands of houses and vast areas of farmland and roads destroyed. In the 2020 edition of Germanwatch's Climate Risk Index, it was judged to be the ninth hardest-hit nation by climate calamities during the period 1999 to 2018. Nepal is a least developed country, with 28.6 percent of the population living in multidimensional poverty. Analysis of trends from 1971 to 2014 by the Department of Hydrology and Meteorology (DHM) shows that the average annual maximum temperature has been increasing by 0.056 °C per year. Precipitation extremes are found to be increasing. A national-level survey on the perception-based survey on climate change reported that locals accurately perceived the shifts in temperature but their perceptions of precipitation change did not converge with the instrumental records. Data reveals that more than 80 percent of property loss due to disasters is attributable to climate hazards, particularly water-related events such as floods, landslides and glacial lake outburst floods (GLOFs).
Climate change is having serious impacts in the Philippines such as increased frequency and severity of natural disasters, sea level rise, extreme rainfall, resource shortages, and environmental degradation. All of these impacts together have greatly affected the Philippines' agriculture, water, infrastructure, human health, and coastal ecosystems and they are projected to continue having devastating damages to the economy and society of the Philippines.
Cambodia is highly vulnerable to the effects of climate change. Extreme weather events will occur more frequently; this includes floods, which already affect 90,000 residents annually, and heatwaves, with Cambodia already having one of the highest temperatures of the world. The temperature has increased since the 1960s by 0.18 °C per decade. It had the 7th lowest CO2 emissions in Asia in 2019.
Climate change is having a considerable impact in Malaysia. Increasing temperatures are likely to greatly increase the number of heatwaves occurring annually. Variations in precipitation may increase the frequency of droughts and floods in various local areas. Sea level rise may inundate some coastal areas. These impacts are expected to have numerous environmental and socioeconomic effects, exacerbating existing environmental issues and reinforcing inequality.
Climate change in Ghana is impacting the people in Ghana in several ways as the country sits at the intersection of three hydro-climatic zones. Changes in rainfall, weather conditions and sea-level rise will affect the salinity of coastal waters. This is expected to negatively affect both farming and fisheries. Low precipitation, drought and wild fires are also some major effects associated with climate change in Ghana.
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.
Climate change is affecting Austrian temperatures, weather, ecosystems and biodiversity. Since 1950 temperatures have risen by 1.8 °C, and in the past 150 years glaciers have melted, losing a significant amount of their volume. Changed precipitation patterns, increased temperatures, reduced snowfall, melting glaciers and more frequent extreme weather phenomenon, such as droughts, are expected effects from climate change. Ecosystems and biodiversity in Austria are facing changes due to increasing temperatures and the spread of thermophile species, heat and drought stress on animals and plants, an increase in alien and invasive species and an increase in pathogenic organisms and the spread of disease.
In Italy, widespread impacts of climate change are currently being felt. With an increase in extreme events such as heatwaves, droughts and more frequent flooding, Italy faces many challenges adapting to climate change.
Iran is among the most vulnerable countries 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.
Due to its geographical and natural diversity, Indonesia is one of the countries most susceptible to the impacts of climate change. This is supported by the fact that Jakarta has been listed as the world's most vulnerable city, regarding climate change. It is also a major contributor as of the countries that has contributed most to greenhouse gas emissions due to its high rate of deforestation and reliance on coal power.
India was ranked seventh among the list of countries most affected by climate change in 2019. India emits about 3 gigatonnes (Gt) CO2eq of greenhouse gases each year; about two and a half tons per person, which is less than the world average. The country emits 7% of global emissions, despite having 17% of the world population. The climate change performance index of India ranks eighth among 63 countries which account for 92% of all GHG emissions in the year 2021.
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.
Climate change in Brazil is mainly the climate of Brazil getting hotter and drier. The greenhouse effect of excess carbon dioxide and methane emissions makes the Amazon rainforest hotter and drier, resulting in more wildfires in Brazil. Parts of the rainforest risk becoming savanna.

has generic name (help)Medium-range estimates of Arctic carbon emissions could result from moderate climate emission mitigation policies that keep global warming below 3°C (e.g., RCP4.5). This global warming level most closely matches country emissions reduction pledges made for the Paris Climate Agreement...
"The IPCC doesn't make projections about which of these scenarios is more likely, but other researchers and modellers can. The Australian Academy of Science, for instance, released a report last year stating that our current emissions trajectory had us headed for a 3°C warmer world, roughly in line with the middle scenario. Climate Action Tracker predicts 2.5 to 2.9°C of warming based on current policies and action, with pledges and government agreements taking this to 2.1°C.
