Ratio of discards from fisheries Ratio of discards from fisheries
The graphic shows the amount of discards in the fishing industry from 1988 to 1992. It is broken down into overall, fish, crustaceans and squid categories. Initiatives have been taken by several organisations, seeking to reduce the amount of discarded fish in future fisheries.

Loss of tropical forest in developing regions, 1980-1990 Loss of tropical forest in developing regions, 1980-1990
The graphic shows the amount and rate of deforestation in Latin America and the Caribbean, Asia and Sub-Saharan Africa from 1980 to 1990. Tropical forests are earth's most complex biome in terms of both structure and species diversity.

Status on cost of establishing a business (compared to per capita income) Status on cost of establishing a business (compared to per capita income)
Bureaucracy and administration by local and national government can present a stumbling block for establishing businesses - in particular for micro, small and medium-sized enterprises. Removing and simplifying these procedures increases the possibilities - in particular for the rural population.

Estimated value of marine biomes Estimated value of marine biomes
An estimation of the financial value of selected different marine areas. Marine biomes are divided between coral reefs, estuaries, and oceans. The marine biome covers 75% of the earth's surface, and accounts for 90% of the planet's water supply.

World consumption and prognoses of primary energy World consumption and prognoses of primary energy
Consumption of non-renewable resources ahve been increasing in most of the world except Eastern Europe and the Former Soviet Union. This graphic shows the world oil, natural gas and coal consumption from various regions in comparison to the world totals. Shows trends from 1990 and predicts the patterns to 2020.

The graphic shows the trend of the number of harmful algal blooms in the Western Atlantic from 1970 to 1996. The excess growth of algae is often caused by pollution, and can have negative or fatal effects on some species of fish.

Number of trees planted, world map - UNEP Billion Tree Campaign, May 2008 Number of trees planted, world map - UNEP Billion Tree Campaign, May 2008
The UNEP Billion Tree Campaign represents a unique worldwide tree planting initiative, aimed at empowering citizens to corporations and people up to presidents to embrace the climate change challenge. By 2008, 18 months since the launch of the initiative, the campaign has managed to catalyze the planting of two billion trees, double its original target. The campaign, spearheaded by the UN Environment Programme (UNEP) and the World Agroforestry Ce...

Global fisheries stock Global fisheries stock
The graphic compares biomass to fish mortality to summarize the amount of exploitation on fish stocks globally. Fish is considered important to human diet, but roughly two-thirds of the world’s major stocks are now fished at or beyond their capacity. Another 6 % is completely depleted.

Sites with dead zones (oxygen depletion on the sea bottom) Sites with dead zones (oxygen depletion on the sea bottom)
Dead zones (hypoxic i.e. oxygen deficient water) in the coastal zones are increasing, typically surrounding major industrial and agricultural centers. This is commonly occuring due to nutrient pollution, in the form of nitrogen and phosphorous leading to algal blooms and eutrophication

Estimated contributions to sea-level rise (1993-2003) Estimated contributions to sea-level rise (1993-2003)
The two main reasons for sea-level rise are thermal expansion of ocean waters as they warm, and increase in the ocean mass, principally from land-based sources of ice (glaciers and ice caps, and the ice sheets of Greenland and Antarctica). Global warming from increasing greenhouse gas concentrations is a significant driver of both contributions to sea-level rise. From 1955 to 1995, ocean thermal expansion is estimated to have contributed about 0....

Cumulative impacts on the marine environment Cumulative impacts on the marine environment
Climate change may, through effects on ocean currents, elevated sea temperatures, coral bleaching, shifts in marine life, ocean acidification and much more severely exacerbate the combined actions of accelerating coastal development, coastal pollution and dead zones, invasive species, bottom trawling and over-harvest. These impacts will be the strongest in 10-15% of the Worlds oceans. These areas, however, are concurrent with the most productive ...

Ratio of wastewater treatment Ratio of wastewater treatment
Sewage treatment is low or absent in many parts of the World, leading to eutrophication of the coastal zone, (toxic) algae blooms and dramatically reduce the ability of coral to recover from bleaching events dramatically. The data reflects the bodies of the UNEP Regional Seas programme.

Human impact in the coastal zones Human impact in the coastal zones
Infrastructure development, intensive agricultural expansion, urbanisation and coastal development are increasing the flow of sediments and sewage into the ocean. The situation is most severe around Europe, the East coast of the United States, East of China and in Southeast Asia. These are also primary fishing grounds. Coastal zones are identified as approximately 75 km from the coastline, and this map identifies the most common impact class in t...

Coastal regions with observations of dense shelf water flushing Coastal regions with observations of dense shelf water flushing
Knowledge and mapping of these processes is still scarce due to uneven research effort. The map shows sites with known dense shelf water cascading phenomena, which often may involve the 'flushing' effect. It is most likely that this phenomenon is also active off the coast of Alaska, Chile, Argentina and West and southern Africa and in parts of the Indian Ocean. Dense shelf water cascading is highly sensitive to increases in temperature, and hence...

World fisheries hotspots, 2004 World fisheries hotspots, 2004
The World’s most productive fishing grounds are confined to major hotspots, less than 10% of the World oceans. The maps shows annual catch (tonnes per km2) for the World’s oceans. Notice the strong geographic concurrence of continental shelves, upwelling and primary productivity and the amount of fish caught by fisheries.
