Global environmental outlook.Five years after the groundbreaking "Earth Summit" at Rio de Janeiro Rio de Janeiro, city, Brazil Rio de Janeiro (rē`ō də zhänā`rō, Port. rē` thĭ zhənĕē`r , "the global environment has continued to deteriorate
and significant environmental problems remain deeply embedded in the
socioeconomic fabric of nations in all regions," concludes the
Global Environment Outlook Report recently released by the United
Nations Environment Program (UNEP UNEP United Nations Environment Program(me)UNEP Unbundled Network Element Platform UNEP University of Northeastern Philippines ) at Nairobi, Kenya. "Internationally and nationally, the funds and political will remain insufficient to halt further global environmental degradation Environmental degradation is the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems and the extinction of wildlife. and to address the most pressing environmental issues - even though the technology and knowledge are available to do so," the report explains. The report points out that "the recognition of environmental issues as necessary long-term and cumulative, with serious global and security implications, remains limited.... The continued preoccupation with immediate local and national issues and a general lack of sustained interest in global and long-term environmental issues remain major impediments to environmental progress internationally." The report argues that although there is repeated acknowledgement' of both the vicious cycle Noun 1. vicious cycle - one trouble leads to another that aggravates the first vicious circle positive feedback, regeneration - feedback in phase with (augmenting) the input of poverty and its intrinsic linkages with the environment and the urgency to address poverty alleviation, little evidence has emerged from regional reports that effective and concerted actions have been taken since Rio to ensure that environmental policies benefit the poorest members of society. "A vacuum still remains at the national level for linking environmental protection to social investment, such as education, better health care and employment generation for the poor, especially women," says the report. At the same time, the report sees encouraging signs in the empowerment of communities and the growth of environment-oriented, non-governmental organizations in civil society, and their increasing recognition in all regions as powerful mechanisms to advance sustainable development Sustainable development is a socio-ecological process characterized by the fulfilment of human needs while maintaining the quality of the natural environment indefinitely.

The Global Environment Outlook Report identifies principal environmental issues confronting the major regions. In regions where food security and poverty alleviation are priorities, 'such as Africa, West Asia and parts of the Asia-pacific region and Latin America Latin America, the Spanish-speaking, Portuguese-speaking, and French-speaking countries (except Canada) of North America, South America, Central America, and the West Indies. , the primary concern is related to land - its availability, the prevention and control of land degradation The causes of land degradation are mainly anthropogenic and agriculture related. The major causes include:
see overstocking. , salinization and alkalinization," says the report. A decline of some two percent of the world's forest area and wooded land over the last decade is another aspect that the report touches upon. While the area under forest cover in developed regions remained fairly unchanged during this period, natural forest cover in developing regions declined by eight percent. African forests are the most depleted de·plete tr.v. de·plet·ed, de·plet·ing, de·pletes To decrease the fullness of; use up or empty out. [Latin d of all the tropical regions, with only 30 percent of historical stands remaining, the report points out. Asian timber reserves may last for no more than 40 years. West Asia lost 11 percent of its remaining forests during the 1980's. In Europe, air pollution (including acid rain), pests and diseases, and forest fires This is a list of notorious forest fires: North America Year Size Name Area Notes 1825 3,000,000 acres (12,000 km²) Miramichi Fire New Brunswick Killed 160 people. were the main causes of forest degradation. The report recognizes that, while total deforestation deforestation Process of clearing forests. Rates of deforestation are particularly high in the tropics, where the poor quality of the soil has led to the practice of routine clear-cutting to make new soil available for agricultural use. has been greatest in Latin America and the Caribbean, deforestation rates have decelerated as a result of international initiatives and national programs to abolish subsidies, tax incentives and special credits that encouraged deforestation. Biological diversity is of particular concern in both the Latin American and Caribbean region and the Asia and Pacific region, which together house 80 percent of the world's ecologically megadiverse countries The megadiverse countries are a group of countries that harbor the majority of the earth's species and are therefore considered extremely biodiverse. The World Conservation Monitoring Centre, an agency of the United Nations Environment Programme, has identified 17 megadiverse . Worldwide habitat loss and fragmentation, the lack of biological corridors and the decline in biological diversity outside protected areas constitute the primary threats to biological diversity. One common factor that links all regions is the problem related to either groundwater or surface water or both. Everyday, 25,000 people die as a result of poor water quality. Some 1,700 million people, more than one third of the world's population, are without a supply of safe water and, in the absence of an adequate sanitation infrastructure, the problem of pathogenic pollution is severe in many developing countries. An estimated one quarter of the world's population will suffer from chronic water shortages in the beginning of the next century. The development and efficient management of water resources are of particular concern in West Asia, Africa and Asia and the Pacific. In Europe and North America North America, third largest continent (1990 est. pop. 365,000,000), c.9,400,000 sq mi (24,346,000 sq km), the northern of the two continents of the Western Hemisphere. , the protection of water resources from contamination, acidification acidification a technology used by processors to preserve foods by adding acids (such as acetic, citric, phosphoric, propionic and lactic acid) and thereby reduce the risk of growth of harmful bacteria. and eutrophication eutrophication (y trō'fĭkā`shən), aging of a lake by biological enrichment of its water. In a young lake the water is cold and clear, supporting little life. feature high on the
agenda. One million rural Americans are without piped water, and
supplies to a further 5.6 million do not meet safe drinking water drinking watersupply of water available to animals for drinking supplied via nipples, in troughs, dams, ponds and larger natural water sources; an insufficient supply leads to dehydration; it can be the source of infection, e.g. leptospirosis, salmonellosis, or of poisoning, e.g. standards. Water supply to regions hosting megacities is a worldwide concern, mainly with regard to groundwater resources, the intrusion of salt into freshwater supplies and land subsidence. More than 1,500 million people depend on groundwater for their drinking water. "Other global priorities are the equitable distribution of water between riparian riparian adj. referring to the banks of a river or stream. (See: riparian rights) countries sharing international river basins and the impacts of major dams and diversion projects. The depletion of aquifers on the western side of the Persian Gulf Persian Gulf, arm of the Arabian Sea, 90,000 sq mi (233,100 sq km), between the Arabian peninsula and Iran, extending c.600 mi (970 km) from the Shatt al Arab delta to the Strait of Hormuz, which links it with the Gulf of Oman. , for example, is leading to the loss of a unique ecosystem of natural freshwater springs. Many countries in West Asia suffer from water scarcity, with Bahrain having less than 18 percent of the minimum threshold; yet levels of water consumption are now very high, ranging from 300 to 1500 liters a day per capita [Latin, By the heads or polls.] A term used in the Descent and Distribution of the estate of one who dies without a will. It means to share and share alike according to the number of individuals. ," the report points out. Currently, Africa has 19 of the 25 countries that have the highest percentage of populations without access to safe drinking water. Acid rain and transboundary air pollution, once considered a problem only in Europe and parts of North America, are now increasingly apparent in parts of Asia and the Pacific and Latin America. Large regions are at risk from the effects of both climate change and acidification. All major cities in the world suffer from urban air quality problems. In Eastern Europe Eastern Europe The countries of eastern Europe, especially those that were allied with the USSR in the Warsaw Pact, which was established in 1955 and dissolved in 1991. , air quality is considered the most serious environmental problem. Despite coordinated action worldwide, damage to the ozone layer ozone layer or ozonosphere, region of the stratosphere containing relatively high concentrations of ozone, located at altitudes of 12–30 mi (19–48 km) above the earth's surface. continues faster than expected, with the next ten years predicted to be the most vulnerable. Non-compliance and growth in illegal trade in ozone depleting substances are emerging problems. Argentina, Brazil, Chile, Paraguay and Uruguay experience the effects of increased ultraviolet-B radiation due to ozone depletion Ozone depletion describes two distinct, but related observations: a slow, steady decline of about 4 percent per decade in the total amount of ozone in Earth's stratosphere since around 1980; and a much larger, but seasonal, decrease in stratospheric ozone over Earth's polar regions more acutely than any other inhabited region. All regions express concern over global warming global warming, the gradual increase of the temperature of the earth's lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution. , but special emphasis is placed by the developing countries on the need for adoptive mechanisms to cope with accompanying climate variability and sea-level change. "The rapidly rising demand for energy to fuel economic development will aggravate these problems," states the report, "particularly in Asia and the Pacific, where a 100 percent increase in energy use is predicted for the period 1990-2010 and in Latin America, with a predicted energy growth of 50-77 percent for the same period." Currently, the impacts of current consumption and production patterns and associated waste generation particularly on personal health and well-being, are high on the priority list of both North America and Western Europe Western Europe The countries of western Europe, especially those that are allied with the United States and Canada in the North Atlantic Treaty Organization (established 1949 and usually known as NATO). , and of concern to the other regions as well. Subregions with emerging economies, such as those of Eastern Europe, South East Asia East Asia A region of Asia coextensive with the Far East. East Asian adj. & n. , and parts of Latin America and West Asia, face problems associated with rapid industrialization industrialization Process of converting to a socioeconomic order in which industry is dominant. The changes that took place in Britain during the Industrial Revolution of the late 18th and 19th century led the way for the early industrializing nations of western Europe and . The accumulation of radioactive waste radioactive waste, material containing the unusable radioactive byproducts of the scientific, military, and industrial applications of nuclear energy. Since its radioactivity presents a serious health hazard (see radiation sickness), disposing of such material is a and the continued impacts of the Chernobyl disaster The reactor accident at the Chernobyl nuclear power plant was the worst in history, resulting in a severe nuclear meltdown. On 26 April 1986 at 01:23:40 a.m. reactor number four at the Chernobyl Nuclear Power Plant located in the former Soviet Union near Pripyat in Ukraine exploded. and the effects of past radioactive spills remain of particular concern in Eastern European countries. These problems are compounded by rapidly increasing urbanization, particularly in coastal zones, and the widening gap between the rich and the poor. The Global Environment Outlook Report identifies seven fundamental global environmental trends that could be crucial in halting environmental degradation and implementing sustainable development: (a) The current use of renewable resources, land, forest, freshwater, coastal areas, fisheries and urban air which is beyond their natural regeneration capacity and therefore unsustainable; (b) The emission of greenhouse gases which are still being emitted at levels higher than the stabilization targets internationally agreed upon under the United Nations Framework Convention on Climate Change; (c) Natural areas, and their attendant biological diversity which are diminishing as a result of the expansion of agricultural land and human settlements; (d) The increasing, pervasive use and spread of chemicals which are causing major health risks, environmental contamination and disposal problems; (e) The continued heavy reliance on hydrocarbons in the energy sector to fuel economic development, a practice which is clearly unsustainable; (f) The rapid unplanned urbanization, particularly in coastal areas, which is placing severe major stress on adjacent ecosystems; and (g) Interactions among global biogeochemical cycles which are leading to widespread ecosystem damage and change. The report also explores four key priority areas for action by the global community that emerge from the Global Environment Outlook Report. "Current patterns of energy use require drastic changes, because of their destructive impacts on land and natural resources, climate, air quality, rural and urban settlements, and human health and well-being. Alternative energy sources need to be vigorously pursued and their applications enhanced. Energy efficiency still needs to be greatly improved, and emissions need to be reduced." The second priority relates to the need for a wider dissemination of appropriate and environmentally sound technologies worldwide. Despite years of deliberation, countries have yet to agree on how to reach consensus on international mechanisms to serve the vital interests of both developers of technologies and those countries that need access to them, as well as on international finance mechanisms." The report lists Global action on fresh water as its third priority. Greater efforts are needed to resolve issues related to land-based sources of pollution, non-point source runoff from agricultural and urban areas, protection of groundwater reserves, water pricing, the impact of development projects on ecosystems, and competing demands for water among different social sectors, among rural and urban communities, and among riparian countries. Fourth, the report identifies the need for investment in new and better national data collection methods and in the acquisition of global datasets and in enhanced capabilities for integrated assessment and forecasting, and analysis of the environmental impact of alternative policy options. Releasing the report, UNEP Executive Director, Ms. Elizabeth Dowedswell said, "The analysis of the state of the environment in the Global Environment Outlook Report takes us into several fields. It takes us into politics, because environmental policy is made in an intensely political atmosphere where interests and values often collide. It takes us into science, which enables us to understand problems and attempts to solve them. It takes us into the field of ethics, because few areas of policy present more difficult choices: how to preserve shared resources, how to distribute costs and benefits, how this generation's actions will affect future ones. It also takes us into economics, because a society's choices about the environment relate directly to how it produces, consumes and preserves its resources." "Solutions to environmental problems do not come from awareness alone," Ms. Dowedswell remarked. "They have to be relentlessly sought after and striven for. Rio was the start of a process: an unprecedented basic framework was agreed upon and many important commitments were made, but some vital issues remain to be set in place. UNEP's Global Environment Outlook Report confirms that there still remains an unfinished agenda." For further information, please contact: Tore J.
