Japan emissions of greenhouse gases (CO2, CH4, N2O) 1990 and 2010 projections
Emissions from human activities, and primarily fossil fuels, contribute to climate change, global warming and the greenhouse effect. This is primarily from industry, energy, transportation and related sectors. Please not...

Solar insolation
Solar insolation, the quantification of energy per surface area on the ground, can be used as an indicator for the potential for solar energy. This map presents solar insolation in Europe and neighboring countries, calcu...

Energy efficiency generally improves with economic growth...but greenhouse gases increase too
In 1992 76 million people living in urban areas were exposed to air pollutant concentrations exceeding WHO guidelines. In developing countries 1.9 million people die each year because of indoor air pollution exposure and...

Global human development indicators
Poverty is multidimensional. It varies in scale and context (political, social, cultural, ecological, historical, economic). The rural poor face different challenges from those in urban areas: they are concerned with nat...

Total carbon market value per year
The total value of the carbon market for 2003 topped $300 million. And, depending on international regulation, some observers project that it will increase to $10–40 billion by 2010. Markets are also being created for mo...

Global production, prices, and undernourishment
Food production more than doubled (an increase of over 160%) from 1961 to 2003. Over this period, production of cereals—the major energy component of human diets—has increased almost two and a half times, beef and sheep ...

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...

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...

Electrification and traditional fuels in Sub-Saharan Africa
The Southern African Development Community (SADC) consists of 15 countries, with 233 million inhabitants. Apart from Mauritius and the countries around South Africa in the Southern African Customs Union (SACU), the remai...

Biofuels production 2005, by country (ethanol and biodiesel)
Production of crops for biofuels also competes with food production (Banse et al., 2008). Indeed, the corn equivalent of the energy used on a few minutes drive could feed a person for a day, while a full tank of ethan...

Relative changes in precipitation
Projections for changes in precipitation patterns are extremely complex, involving a high degree of uncertainty and large heterogeneity. Summer climate projections under climate change scenario A1B (this scenario assumes...

Index of biodiversity potential in Central America
Biodiversity is vitally important to human well-being as it provides ecosystem services on which humans depend. For many species that are sensitive to even small variations in climate, their primary threat is climate cha...

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 climati...

Sustainable development mechanism projects by type
Of the 1003 projects falling under the framework of Clean Development Mechanism (CDM) which have been implemented in the region of Latin America and the Caribbean, the majority of the projects are related to renewable en...

Energy supply in Latin America
Although 70% of South America’s electricity comes from hydroelectric sources, the situation in Central America and the Caribbean is quite different. In these two regions electric-power generation rely predominantly on fo...

Mean changes in runoff
Changes in precipitation and temperature influence changes in runoff and the availability of water. Results from models of changes in runoff are consistent with predictions for precipitation. For 2090-2099, in areas for ...

Warming of the earth's surface
Climate projections for Latin America and the Caribbean indicate that temperature increases will vary according to the particular emissions scenario and country or region concerned. According to the A1B climate change sc...

Greenhouse effect
Human activities are causing greenhouse gas levels in the atmosphere to increase. This graphic explains how solar energy is absorbed by the earth's surface, causing the earth to warm and to emit infrared radiation. The g...
