Soy Expansion in the Brazilian Amazon frontier Soy Expansion in the Brazilian Amazon frontier
Often, small-scale farmers settle the areas along logging roads in order to burn secondary or cleared forest for crop production. These farmers are eventually pushed or bought-out by large-scale cattle ranchers or soy prodcution owners.

Plantation in Indonesia: a new frontier in black wood laundering? Plantation in Indonesia: a new frontier in black wood laundering?
Much of the logging in Indonesia, takes place in association with the establishment of palm oil or other plantations. As the forest is cleared for plantations, it is common practic to cut beyond the plantation area, or to get a permit for a larger area than initially planted.

Differentiation between crops, land-use and end-use efficiency Differentiation between crops, land-use and end-use efficiency
The energy gain from biofuels is often expressed as a ratio of biofuel energy output to fossil energy input. However, when considering which biofuels are the most efficient using this metric, allowance must also be made for whether or not co-products such as animal feed and other forms of energy or biomass production are involved. Economically, the value of co-products is also critical; and together with various subsidies and tax incentiv...

CO2 air emissions by sources in 1995 CO2 air emissions by sources in 1995
The graph shows CO2 air emissions from selected countries by various sources in 1995. Among the anthropogenic sources of CO2 air emissions are fossil fuel combustion, cement production and land-use conversion.

Arable land in the Baltic Sea region Arable land in the Baltic Sea region
Ratio of arable land out of total land use in the Baltic Sea drainage basin. Agriculture is one of the main contributors to the nutrient (in this case, primarily nitrogen) influx into the Baltic Sea, and thus a main driver for the eutrophication problems in the sea. The displays the situation at approximately 1990.

CO2 emissions from industrial processes and land use changes CO2 emissions from industrial processes and land use changes
Shows the different levels of CO2 emissions from industrial processes and land use changes from different regions. The major greenhouse gases are included within six sectors: Energy; Industrial Processes; Solvent and Other Product Use; Agriculture; Land Use Change and Forestry; and Waste. Contributing to emissions Historically the developed countries of the world have emitted most of the anthropogenic greenhouse gases. The U.S. emits most in t...

CO2 emissions in 1990 and 2000 Latin America and selected countries CO2 emissions in 1990 and 2000 Latin America and selected countries
A comparison of the total level of CO2 emissions from Latin America compared to selected countries. Emissions from Latin America and Caribbean increased more than the world average between 1990 and 2000. The increase inthis region was more than 35% while the total increase in the world's emission (excluding land use change) was almost 13%. In South America the increase came mainly from industry and transport, where emissions increased by more t...

Annual deforestation in the Amazon and resulting CO2 emissions Annual deforestation in the Amazon and resulting CO2 emissions
According to the World Resources Institute,Brazil had the highest carbon dioxide equivalent emissions in the region in 2001, primarily due to changes in land use.) Most of the region’s forests are in South America, particularly in Brazil and Peru, which comprise 92% of the total forest cover. These countries are among the 10 that hold two-thirds of the world’s forests and jungles. Because of its size, the greatest extent of deforestation is in B...

A comparison between the amount of CO2 emissions of the world and latin America and the Caribbean. Since pre-industrial times, the atmospheric concentration of greenhouse gases has grown significantly. The present level of carbon dioxide concentration (around 375 parts per million) is the highest for 420,000 years, and probably the highest for the past 20 million years. CO2 is the greenhouse gas that contributes most to the enhanced greenhouse e...

Brazil is the world’s second largest emitter of carbon dioxide (CO2) from land use change. Only Indonesia emits more. In 2000 CO2 emissions from land use change in Brazil represented 18% of the world’s total emissions. The per capita emissions from land use change in Brazil are 6 times higher than the world average. Most of the land use change emissions in Brazil are caused by the massive logging of its rainforest. The per capita emissions of C...

CO2 emissions from land use change CO2 emissions from land use change
Emissions of carbon dioxide due to changes in land use mainly come from the cutting down of forests and instead using the land for agriculture or built-up areas, urbanisation, roads etc. When large areas of rain forests are cut down, the land often turns into less productive grasslands with considerably less capacity of storing CO2.

Forest Cover and Definition Forest Cover and Definition
Forest cover varies depending on how it is defined. The crown cover threshold and the land use criterion are, in most cases, the most critical factors defining forests.

Emissions of CO2 per capita 1990 (selected countries) Emissions of CO2 per capita 1990 (selected countries)
The graph shows emissions of CO2 per capita 1990. CO2 can be emitted as byproduct from the use of fossil fuel, by combustion, land-use conversion and cement production. Atmospheric concentrations of CO2 are increasing, and it is indicated that this contributes to global warming and climate change.

The graphic shows the world's total CO2 emissions in million metric tonnes carbon equivalent. Broken down into categories of total fuel fossil emissions, oil, natural gas and coal. CO2 is one of the main greenhouse gases and can, in addition to fossil fuel combustion( as shown on graph), be produced by cement production and land use conversion such as deforestation.

Coral reefs at risk from human activities Coral reefs at risk from human activities
Population growth and technology: operating together these two factors account for the major causes of coral reef decline - excessive domestic and agricultural waste pouring into ocean waters, poor land-use practices that increase sedimentation of rivers and then of reefs, and over-exploitation of reef resources, often in combination with practices such as harvesting with dynamite and poison, all degrade reefs.

The significant part of carbon dioxide emissions comes from energy production, industrial processes and transport. The industrialised countries consequently must bear the main responsibility of reducing emissions of carbon dioxide. (2): CO2 emissions from land use change.(...

Acidification due to climate change - impacts for oceans and coral reefs Acidification due to climate change - impacts for oceans and coral reefs
As carbon concentrations in the atmosphere increase from land use changes and emissions from fossil fuels - so do concentrations in the ocean, with resultant acidification as a natural chemical process. The skeletons of coldwater coral reefs may dissolve, perhaps already within a few decades. The impacts will be greatest at high latitudes. This will have an impact on all marine organisms with calcerous shells and body parts, in addition to coral ...
