The United Nations Environment Programme (UNEP) is responsible for coordinating responses to environmental issues within the United Nations system. It was established by Maurice Strong, its first director, after the United Nations Conference on the Human Environment in Stockholm in June 1972. Its mandate is to provide leadership, deliver science and develop solutions on a wide range of issues, including climate change, the management of marine and terrestrial ecosystems, and green economic development. The organization also develops international environmental agreements; publishes and promotes environmental science and helps national governments achieve environmental targets.
An island country, island state, or island nation is a country whose primary territory consists of one or more islands or parts of islands. Approximately 25% of all independent countries are island countries. Island countries are historically more stable than many continental states but are vulnerable to conquest by naval superpowers. Indonesia is the largest and most populated island country in the world.
The Indian Ocean Rim Association (IORA), formerly known as the Indian Ocean Rim Initiative (IORI) and the Indian Ocean Rim Association for Regional Cooperation (IOR-ARC), is an international organisation consisting of 23 states bordering the Indian Ocean. The IORA is a regional forum, tripartite in nature, bringing together representatives of Government, Business and Academia, for promoting co-operation and closer interaction among them. It is based on the principles of for strengthening Economic Cooperation particularly on Trade Facilitation and Investment, Promotion as well as Social Development of the region. The Coordinating Secretariat of IORA is located at Ebene, Mauritius.
Sustainable tourism is a concept that covers the complete tourism experience, including concern for economic, social and environmental issues as well as attention to improving tourists' experiences and addressing the needs of host communities. Sustainable tourism should embrace concerns for environmental protection, social equity, and the quality of life, cultural diversity, and a dynamic, viable economy delivering jobs and prosperity for all. It has its roots in sustainable development and there can be some confusion as to what "sustainable tourism" means. There is now broad consensus that tourism should be sustainable. In fact, all forms of tourism have the potential to be sustainable if planned, developed and managed properly. Tourist development organizations are promoting sustainable tourism practices in order to mitigate negative effects caused by the growing impact of tourism, for example its environmental impacts.
Today, environmental problems in the Philippines include pollution, mining and logging, deforestation, threats to environmental activists, dynamite fishing, landslides, coastal erosion, biodiversity loss, extinction, global warming and climate change. Due to the paucity of extant documents, a complete history of land use in the archipelago remains unwritten. However, relevant data shows destructive land use increased significantly in the eighteenth century when Spanish colonialism enhanced its extraction of the archipelago's resources for the early modern global market. The Philippines is projected to be one of the most vulnerable countries to the impacts of climate change, which would exacerbate weather extremes. As the Philippines lies on the Pacific Ring of Fire, it is prone to natural disasters, like earthquakes, typhoons, and volcanic eruptions. In 2021, the Philippines ranked the fourth most affected country from "weather-related loss events", partly due to the close proximity of major infrastructure and residential areas to the coast and unreliable government support. One of the most devastating typhoons to hit the archipelago was Typhoon Haiyan, known locally as Yolanda, in 2013 that killed 6,300 people and left 28,689 injured. Congress passed the Clean Air Act of 1999, the Philippine Clean Water Act of 2004, the Climate Change Act of 2009 to address environmental issues. The country is also a signatory to the Paris Agreement. However, research has found that outside of cities, the general public doesn't feel equally informed. Environmental activists and land defenders, consisting mostly of Indigenous communities who have been attempting to bring attention to the environmental issues in the country have been met with violence or murder. As a result, the Philippines has been ranked one of the most dangerous places in the world for environmental activists.
Environmental issues in Pakistan include air pollution, water pollution, noise pollution, climate change, pesticide misuse, soil erosion, natural disasters, desertification and flooding. According to the 2020 edition of the environmental performance index (EPI) ranking released by Yale Center for Environmental Law & Policy, Pakistan ranks 142 with an EPI score of 33.1, an increase of 6.1 over a 10-year period. It ranked 180 in terms of air quality. The climatic changes and global warming are the most alarming issues risking millions of lives across the country. The major reasons of these environmental issues are carbon emissions, population explosion, and deforestation.
Fisheries are affected by climate change in many ways: marine aquatic ecosystems are being affected by rising ocean temperatures, ocean acidification and ocean deoxygenation, while freshwater ecosystems are being impacted by changes in water temperature, water flow, and fish habitat loss. These effects vary in the context of each fishery. Climate change is modifying fish distributions and the productivity of marine and freshwater species. Climate change is expected to lead to significant changes in the availability and trade of fish products. The geopolitical and economic consequences will be significant, especially for the countries most dependent on the sector. The biggest decreases in maximum catch potential can be expected in the tropics, mostly in the South Pacific regions.
Climate change in Sri Lanka is an important issue, and its effects threaten to impact both human and natural systems in Sri Lanka. Roughly 50 percent of its 22 million citizens live in low-lying coastal areas in the west, south, and south-west of the island, and are at risk of future sea level rise. Climate change also threatens the island's biodiversity, including its marine ecosystem and coastal coral reef environments. Sea-level rise due to climate change has the potential to affect the overall abundance of endemic species. Sri Lanka's coastal regions, such as the Northern Province and the Northern Western Province, are considered major hotspots and extremely vulnerable to climate change. These maritime provinces are the most densely populated. In addition to being a threat to Sri Lanka's biodiversity, climate change may cause disastrous consequences on various levels in such areas. Such consequences include: Affecting agricultural productivity, causing natural disasters like floods and droughts, increasing the spread of infectious illnesses, and finally undermining the living standards.
Climate change in Bangladesh is a critical issue as the country is one of the most vulnerable to the effects of climate change. In the 2020 edition of Germanwatch's Climate Risk Index, it ranked seventh in the list of countries most affected by climate calamities during the period 1999–2018. Bangladesh's vulnerability to the effects of climate change is due to a combination of geographical factors, such as its flat, low-lying, and delta-exposed topography, and socio-economic factors, including its high population density, levels of poverty, and dependence on agriculture. The impacts and potential threats include sea level rise, temperature rise, food crises, droughts, floods, and cyclones.
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 finance are funding processes for investments related to climate change mitigation and adaptation. The term has been used in a narrower sense to refer to transfers of public resources from developed to developing countries, in light of their UN Climate Convention obligations to provide "new and additional financial resources". In a wider sense, the term refers to all financial flows relating to climate change mitigation and adaptation.
The effect of climate change on small island countries can be extreme because of low-lying coasts, relatively small land masses, and exposure to extreme weather. The effects of climate change, particularly sea level rise and increasingly intense tropical cyclones, threaten the existence of many island countries, island peoples and their cultures, and will alter their ecosystems and natural environments. Several Small Island Developing States (SIDS) are among the most vulnerable nations to climate change.
Nature-based solutions (NBS) is the sustainable management and use of natural features and processes to tackle socio-environmental issues.
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 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.
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.
Sustainable Development Goal 13 is to limit and adapt to climate change. It is one of 17 Sustainable Development Goals established by the United Nations General Assembly in 2015. The official mission statement of this goal is to "Take urgent action to combat climate change and its impacts". SDG 13 and SDG 7 on clean energy are closely related and complementary.
Sustainable Development Goal 11, titled "sustainable cities and communities", is one of 17 Sustainable Development Goals established by the United Nations General Assembly in 2015. The official mission of SDG 11 is to "Make cities inclusive, safe, resilient and sustainable". The 17 SDGs take into account that action in one area will affect outcomes in other areas as well, and that development must balance social, economic and environmental sustainability.
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.
