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 fishe...

Woodfuel and energy consumption
Biomass, primarily woodfuel, is the major source of energy in Sub-Saharan Africa, with the exception of South Africa. Over 90% of the total energy consumption is biomass in Ethiopia, DPR Congo and Tanzania. Projections e...

Renewable energy production in Europe and Central Asia 2004 (heat production and electricity generation)
Hydropower, generation of electricity from dams in rivers, represents the majority of the energy produced, so far, with waste incineration - both from municipal and industrial sources, as a distant second. Other energy s...

Collapse of Atlantic cod stocks off the East Coast of Newfoundland in 1992
From the late 1950s, offshore bottom trawlers began exploiting the deeper part of the stock, leading to a large catch increase and a strong decline in the underlying biomass. Internationally agreed quotas in the early 19...

Changes in forest area
Timber is harvested from forests and plantations and used for a variety of building, manufacturing, fuel, and other needs. Forests (providing fuelwood and charcoal), agricultural crops, and manure all serve as sources of...

From biomass to energy consumption
As biomass feedstocks are widely available, bioenergy offers an attractive complement to fossil fuels and thus has potential to alleviate concerns of a geopolitical and energy security nature. However, only a small part ...

Areas of physical and economic water scarcity
Under current water use practices, increases in population and changes in diet are projected to increase water consumption in food and fiber production by 70-90%. If demands for biomass energy increase, this may aggravat...

Natural resource - solar power (potential)
More than two billion people cannot access affordable energy services today. They depend on inefficient locally collected and often unprocessed biomass-based fuels, such as crop residues, wood, and animal dung. Because c...

Ecoregions in Antarctica
Antarctica represents a very unique and special case on our planet. With the richness of the Southern Ocean, the coasts and the Southern islands have relatively high biodiversity and biomass in the form of numerous sea b...

Trends in vegetation biomass, Ellsmere Island 1995-2007
Data from many sources and at several scales suggest that recent climate change is already affecting terrestrial Arctic ecosystems. Comparisons of historical and contemporary aerial photographs provide evidence that Arct...

Above-ground carbon stocks
Some of the richest above-ground carbon stocks are found in forests occupied by Sumatran orangutans. The total carbon stored in the above-ground woody biomass of a tropical forest varies between 170 and 250 tonnes of car...
