Greenhouse gas emissions from agriculture and land use Greenhouse gas emissions from agriculture and land use
Changes in land use have negatively affected the net ability of ecosystems to sequester carbon from the atmosphere. For instance, the carbon rich grasslands and forests in temperate zones have been replaced by crops with much lower capacity to sequester carbon.

Poverty mapping study area Poverty mapping study area
This map represents the study area for the poverty mapping project for West Africa for generation of reliable statistical and cartographic products to communicate the relationship between rural poverty and land use potential in West Africa, in order to provide information to ensure optimal use of research investment.

The economy of legal wildlife trade The economy of legal wildlife trade
The trade in wild species can contribute significantly to rural incomes, and the effect upon local economies can be substantial. The high value of wildlife products and derivatives can also provide positive economic incentives to provide an alternative to other land use options for the local people - to protect wild species and their habitats, and to maintain the resource for sustainable and profitable use in the medium and long term. Consequent...

The development potential - available land per capita, in land use class The development potential - available land per capita, in land use class
The amount of land area available per capita provides a rough measure on the current carrying capacity for food security and for the development of additional agricultural products for export – such as biofuels. The calculation presented in this figure show that most of Asia is very limited in this respect, especially since populations are expected to increase. Latin America and parts of Sub-Saharan Africa show more potential for the development ...

Forest vs. Agriculture – the case of the Mabira forest reserve, Uganda Forest vs. Agriculture – the case of the Mabira forest reserve, Uganda
The Mabira forest reserve, on the shores of Lake Victoria hosts valuable wildlife, serves as a timber resource, provides ecosystem services for the water balance and the rainforests represents a tourist destination. Following a proposed plan for clearing a third of the reserve for agricultural use, the values of the forest were calculated by local researchers. This economic evaluation of the forest shows that from a short-term perspective, growin...

Potential for cropland expansion Potential for cropland expansion
Current projections suggest that an additional 120 million ha – an area twice the size of France or one-third that of India – will be needed to support the traditional growth in food production by 2030, mainly in developing countries (FAO, 2003), without considering the compensation required for certain losses. The demand for irrigated land is projected to increase by 56% in Sub- Saharan Africa (from 4.5 to 7 million ha), and rainfed land b...

Projected land use changes Projected land use changes
A central component in preventing loss of biodiversity and ecosystem services, such as provisioning of water, from expanding agricultural production is to limit the trade-off between economic growth and biodiversity by stimulating agricultural productivity and more efficient land use. Further enhancement of agricultural productivity (‘closing the yield gap’) is the key factor in reducing the need for land and, consequently, the rate of bio...

Forest, crops and the people Forest, crops and the people
There are competing demands for land use. Any policy that aims to promote ecosystem carbon management must resolve conflicts between different land uses and take care not to disadvantage the poor.

Greenhouse gas emissions per capita in Latin America and the Caribbean, 2005 Greenhouse gas emissions per capita in Latin America and the Caribbean, 2005
In 2005, per capita emissions in Latin America and the Caribbean, not taking emissions associated with land use changes into account, amounted to 5.5 MtCO2-e, with Trinidad and Tobago, Uruguay and the Bolivarian Republic of Venezuela having the highest levels of per capita emissions. On the other end of the spectrum, Guatemala, El Salvador and Haiti had the lowest emission levels in the region.

A strong heterogeneity in the ratio emission to GDP, including the land use change, is observed among the countries of the region. Brazil, Uruguay, Paraguay and Bolivia stand out because of the importance of emissions related to agriculture, forestry and other land uses (AFOLU).

Energy intensity of economy: Percentage growth from 1980 Energy intensity of economy: Percentage growth from 1980
Emissions increase as economies and populations grow; however, there can also be an energy decoupling (relation between energy and GDP) and a decoupling of emissions and decarbonization (relation between emissions and energy consumption). In this way, an increase in per capita income is achieved with less energy consumption and reduced emissions (ECLAC, 2009). Examining an energy intensity index by region for 1980-2005, one sees that, in aggregat...

In 2005 the countries of Latin America and the Caribbean accounted for only 8% of global greenhouse gas emissions, excluding emissions associated with land use changes. Between 1990 and 2005, such emissions in the region increased at an average annual rate of 2.3%, owing to a variety of economic, social and demographic factors. In percentage terms, 2005 emissions increased the region’s share of emissions by one percentage compared to 1990. Nevert...

The region of Latin America and the Caribbean is highly vulnerable to climate change despite the fact that it contributes relatively little to global greenhouse gas emissions. Thus, global carbon dioxide (CO2) emissions in 2006 (excluding those associated with land use changes) amounted to 38,754 million of metric tons of CO2 equivalent (MtCO2-e), with Mexico and Brazil being the main emitters in the region (WRI, 2010). The importance of Latin Am...

Taking into account total CO2 emissions, including those associated with and use changes, the Latin American and Caribbean region rates poorly compared to other regions with regard to emissions of CO2 equivalent per US$ million of GDP produced. Latin America emits 1,152 tonnes of CO2 equivalent per US$ 1 million, compared to 481 tonnes of CO2 equivalent per US$ 1 million emitted by the OECD countries. This indicates that for each US$ million of G...

Greenhouse gas emissions scenarios and surface temperature projections Greenhouse gas emissions scenarios and surface temperature projections
Climate change manifests itself primarily through a gradual increase in the average temperatures of the earth’s surface, alterations in precipitation patterns, changes in the intensity and/or frequency of extreme climatic events, a slow but significant reduction in the cryosphere (including glaciers) and a rise in sea levels. Available scientific evidence associates the phenomenon of climate change with increased concentrations of anthropogenic g...

Emissions of the Brazilian Amazon Emissions of the Brazilian Amazon
Brazil has been recognized as the fifth highest emitter of greenhouse gasses in the world, and is also the highest emitter within the Latin American and Caribbean region. This high level of emission is first and foremost due land use changes within the country. In 2005, forest and grassland conversion was responsible for emitting more than one billion of metric tons of CO2 equivalent (MtCO2-e) in the Brazilian Amazon.

Examining CO2 emissions in 2005, excluding those associated with land use changes, it can be seen that the Latin American and Caribbean region has a higher level of emissions per US$ million of GDP (598 tonnes of CO2 equivalent per US$ 1 million) than the OECD countries (468 tonnes of CO2 equivalent per US$ 1 million), but less than the world average (652 tonnes of CO2 equivalent per US$ 1 million).

The disaggregation of emissions by type of gas makes clear the domination of carbon dioxide (CO2), both globally and at the regional level. On a country basis, the five top emitters in the world are China and the United States, followed by Russia and Japan. The fifth top emitter is Brazil, when greenhouse gas emission associated with land use change is taken into account.

According to reports from the region’s countries, contained in national communications to the United Nations Framework Convention on Climate Change, the main sources of greenhouse gas emissions relate to changes in land use, forestry, agriculture and energy consumption. Brazil stands out as the highest emitter of greenhouse gasses caused by land use changes, accounting for more than 800,000 metric tons of CO2 equivalent. The importance of agricul...
