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. [1] Changes in rainfall, weather conditions and sea-level rise [2] will affect the salinity of coastal waters. This is expected to negatively affect both farming and fisheries. [3]
The national economy stands to suffer from the impacts of climate change because of its dependence on climate-sensitive sectors such as agriculture, energy, and forestry. Moreover, access to freshwater is expected to become more challenging while reduced water supply will have a negative impact on hydropower, which provides 54% of the country's electricity capacity. [3] Additionally, Ghana will likely see more cases of malaria and cholera since changes in water conditions impact both.
In 2015, the government produced a document titled "Ghana's Intended Nationally Determined Contribution". [4] Following that, Ghana signed the Paris Climate Agreement in 2016. The Intended Nationally Determined Contribution after 2016 became the Nationally Determined Contributions commonly referred to as NDCs, which was reviewed in 2021.
A 2023 report by the USDA Foreign Agricultural Service noted that Ghana "is vulnerable to rising sea levels, droughts, increasing temperatures, and erratic rainfall which adversely impacts infrastructure, hydropower production, food security, and coastal and agricultural livelihoods". [5]
In 2021, Ghana's total CO2 emissions from fuel combustion in the energy sector reached 21.397 million tonnes, highlighting a significant increase of 332% in per-capita emissions since 2000. Despite representing only 0.1% of global emissions from combustible fuels, this rise is concerning, particularly in international efforts to mitigate climate change impacts. West Africa is among the smallest contributors to global greenhouse gas emissions, but the nations "are already feeling the effects of the climate crisis disproportionately". [7]
The primary source of these emissions in Ghana was oil burning, which accounted for 66% of the total CO2 emissions from fuel combustion. Sector-wise, transportation emerged as the largest contributor, responsible for 47% of the nation's energy-related CO2 emissions, followed by electricity and heat production at 34%. These figures underscore the urgent need for Ghana to transition towards more sustainable energy sources and improve the efficiency of its transportation and power sectors. [8]
The Jubilee offshore oil field began production in 2010, raising expectations for wealth creation in Ghana. However, the infrastructure needed to support Ghana's oil industry (storage, shipping, processing) has necessitated the practice of flaring. "Long-term gas flaring at the Jubilee Field may be inevitable" without accelerated development of infrastructure and would produce about 1.5 million tons of CO2 annually (7 percent of Ghana's total national emissions). [9]
Lake Volta, the largest artificial lake by surface area in the world, changed climate patterns in Ghana. [13]
The drier northern areas have warmed more rapidly than southern Ghana. Overall, Ghana has experienced a 1.0 °C increase in temperature since 1960. [9] Northern Ghana has only one rainy season, while southern Ghana has two, and annual rainfall is highly variable. Long-term trends for rainfall are challenging to predict. However, USDA's Forest Service concluded in 2011 that there was "no evidence that extreme rain events have either increased or decreased since 1960." [9]
However, when one compares the Köppen-Geiger climate classification map for 1980–2016 and the projected map for 2071–2100 predicted change in classification from "tropical, savannah" to "arid, steppe, hot" in some coastal areas."
Available data also shows a sea level rise of 2.1 mm per year over the last 30 years, indicating a surge of 5.8 cm, 16.5 cm, and 34.5 cm by 2020, 2050, and 2080. [14] [15] Flooding affects approximately "45,000 Ghanaians every year, and half of Ghana's coastline is vulnerable to erosion and flooding as a result of sea-level rise". [16]
Expected decreases in water in the primary river basins providing fresh water for the country, Volta River, Bia River, and Tano River, could increase challenges in getting access to clean drinking water. [3] The volume of water in the Volta Basin was predicted to have a 24% and 45% reduction in 2050 and 2100, respectively. [3] The continuous decrease in precipitation and increasing evaporation rate has the potential to cause political tension in the region as Burkina Faso plans to draw water from the Volta Basin.
Forty-five percent of the workforce in Ghana depends on small-holder rain-fed agriculture. [3] Disruption due to erratic rainfall and other extreme weather will harm people's economic well-being. [3] Moreover, staple crops such as Cassava, Maize, and cocoa (the major cash crop of Ghana) are expected to see decreased production. [3] Based on a 20-year baseline climate observation, it is forecasted that maize and other cereal crop yields will reduce by 7% by 2050.
Moreover, the combination of deforestation and new dams that dried up rivers has affected agriculture and, in turn, brought migration to Accra, which increased poor-quality unplanned settlements in the path of potential flash floods. [17]
A 2024 World Bank report estimates that about two million Ghanaians are vulnerable to food insecurity. [18] Should any natural disaster occur, food availability will be significantly affected, particularly in the Northern region and the country's rural areas. [18]
Seafood makes up 40–60 percent of protein intake in Ghana. [3] Key species for the economy are expected to have worse reproduction cycles . [3] Reduction in fisheries production has stimulated importation of more $200million per year worth of seafood. [19]
Because 54% of the national generation capacity is hydropower, unpredictable rainfall is likely to add uncertainty to a power grid already experiencing frequent outages (known as dumsor). [3] Some estimates suggest that capacity could fall by as much as 50% for the Volta Basin. [3] Ghana experienced a reduction in GDP between 2012 and 2015 in partial response to a deficient supply of power. [3]
An increase in waterborne diseases such as cholera and mosquito-borne diseases like malaria is projected. [3] According to the World Bank, Ghana's health system is highly vulnerable to the changes climate, "especially to iillnesseslike malaria and diarrhea disease ... health issues related to heat, air pollution, and infectious diseases are on the rise with the elderly, youth, and children being particularly vulnerable". [18]
Ghana signed the Paris Agreement on 22 April 2016 and ratified it on 21 September 2016. The first national climate change adaptation strategy in Ghana was developed to be implemented between 2010 and 2020. [20] Adaptation seeks to lower the risks posed by the consequences of climate change. Adaptation measures may be planned or put in place spontaneously in response to local pressure, such as afforestation, land rotation, building climate-resilient structures, solar-powered infrastructure, etc. [21] The Ministry of Environment Science, Technology and Innovation published a policy framework in 2013. [22]
In 2015, Ghana developed a framework entitled "Ghana's Intended Nationally Determined Contribution" to outline a plan to reduce carbon emissions and to improve eternity of land use, transportation, and other economic and societal sectors. [4] This plan, after the Paris Agreement in 2016, became the Nationally Determined Contribution (NDC).
Ghana is experiencing population growth, has a high poverty rate, and its economy is dependent on vulnerable industries like agriculture. Thus, it is a West African country with increased risk of climate vulnerability, including droughts and floods, hunger and disease, that increase human suffering, violence, displacement, and economic collapse in the region. [7]
Ghanaian President Nana Akufo-Addo, the President of Ghana stated, "Our hope depends on the actions we take today." [7] However, Ghana still needs to develop long-term contingency plans for climate change because decision-makers and local managers have an inadequate perception of the costs of dealing with such crises. [17] A 2022 report by the World Bank report noted that Ghana has slowed progress in its economic development and has not fully converted its natural wealth into sufficient infrastructure, human, and institutional capital for sustained growth, but taking a climate resilient and low-carbon pathway could turn challenges into opportunities. [16] With appropriate reforms and investments, it will be possible for Ghana to "deliver large economic and social benefits for its people". [23]
Ghana became a party to the UNFCCC in September 1995, and ratified the Paris Agreement in September 2016. [24] As a party to the Paris Agreement, Ghana is expected to develop a National Adaptation Plan that outlines strategies the country is taking to adjust to the changing climatic conditions.
Climate change adaptation involves adjusting or developing structure to help one live with the impacts of actual or expected future climate. The objective of adaptation is to reduce the impacts of the harmful effects of climate change (like sea-level rise, more intense extreme weather events, or food insecurity). It also includes making the most of any potential beneficial opportunities associated with climate change. [25]
It is estimated that climate change will add to the human and economic toll of floods and droughts in Ghana, which will have direct impacts on key development areas like food security, water resource management, health, and economic growth. [26]
Against this backdrop, the government of Ghana and other International Development Partners have set out approaches to determine vulnerability and adaptation priorities and to integrate this knowledge into development and sectoral planning. [27]Climate change is an urgent and significant issue affecting Japan. In recent years, the country has observed notable changes in its climate patterns, with rising temperatures serving as a prominent indicator of this phenomenon. As an archipelago situated in northeastern Asia, Japan is particularly vulnerable to the impacts of climate change due to its diverse geography and exposure to various weather systems. The nation experiences a broad range of climates, spanning from the frigid winters of Hokkaido to the subtropical climates of Okinawa. Changes in temperature patterns have the potential to disrupt ecosystems, impact agricultural productivity, modify water resources, and pose significant challenges to infrastructure and human settlements.
The climate of Ghana is tropical. The eastern coastal belt is warm and comparatively dry, the south-west corner of Ghana is hot and humid, and the north of Ghana is hot and dry. Ghana is located on the Gulf of Guinea, only a few degrees north of the Equator, giving it a warm climate.
Climate change has resulted in an increase in temperature of 2.3 °C (2022) in Europe compared to pre-industrial levels. Europe is the fastest warming continent in the world. Europe's climate is getting warmer due to anthropogenic activity. According to international climate experts, global temperature rise should not exceed 2 °C to prevent the most dangerous consequences of climate change; without reduction in greenhouse gas emissions, this could happen before 2050. Climate change has implications for all regions of Europe, with the extent and nature of impacts varying across the continent.
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.
Climate changein the Caribbean poses major risks to the islands in the Caribbean. The main environmental changes expected to affect the Caribbean are a rise in sea level, stronger hurricanes, longer dry seasons and shorter wet seasons. As a result, climate change is expected to lead to changes in the economy, environment and population of the Caribbean. Temperature rise of 2 °C above preindustrial levels can increase the likelihood of extreme hurricane rainfall by four to five times in the Bahamas and three times in Cuba and Dominican Republic. Rise in sea level could impact coastal communities of the Caribbean if they are less than 3 metres (10 ft) above the sea. In Latin America and the Caribbean, it is expected that 29–32 million people may be affected by the sea level rise because they live below this threshold. The Bahamas is expected to be the most affected because at least 80% of the total land is below 10 meters elevation.
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 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 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.
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.
Vietnam is among the most affected countries by global climate change. A large number of studies show that Vietnam is experiencing climate change and will be severely negatively affected in coming decades. These negative effects include sea level rise, salinity intrusion and other hydrological problems like floods, river mouth evolution and sedimentation. Natural hazards such as cold waves, storm surges will increase in frequency, with negative effects on the country's development, infrastructure and economy.
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.
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.
Climate change in Liberia causes many problems as Liberia is particularly vulnerable to climate change. Like many other countries in Africa, Liberia both faces existing environmental issues, as well as sustainable development challenges. Because of its location in Africa, it is vulnerable to extreme weather, the coastal effects of sea level rise, and changing water systems and water availability. Climate change is expected to severely impact the economy of Liberia, especially agriculture, fisheries, and forestry. Liberia has been an active participant in international and local policy changes related to climate change.
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 Fiji is an exceptionally pressing issue for the country - as an island nation, Fiji is particularly vulnerable to rising sea levels, coastal erosion and extreme weather. These changes, along with temperature rise, will displace Fijian communities and will prove disruptive to the national economy - tourism, agriculture and fisheries, the largest contributors to the nation's GDP, will be severely impacted by climate change causing increases in poverty and food insecurity. As a party to both the Kyoto Protocol and the Paris Climate Agreement, Fiji hopes to achieve net-zero emissions by 2050 which, along with national policies, will help to mitigate the impacts of climate change.
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. Climate change is the result of the Earth's climate undergoing long-term changes due to the release of greenhouse gases like carbon dioxide (CO2) and methane (CH4). These gases trap heat in the atmosphere, leading to global warming and a hotter planet. Human activities, such as the use of fossil fuels, as well as large-scale commercial agriculture and deforestation, are responsible for the release of these greenhouse gases. The country's contribution to greenhouse gas emissions is very minimal.
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, a small coastal nation situated along the Red Sea in the Horn of Africa, 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.
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.
