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...

Energy resources, production and transportation
Energy is vital for the internal and external security of all three countries (see figure). A secure, affordable domestic energy supply is critical to economic development, particularly in energy hungry industrial sector...

Environment and security issues in Ukraine
Compared to its neighbours, Ukraine has a very low Environmental Sustainability Index (ESI) (ranking 108 out of 146 countries; Esty et al. 2005). This is primarily due to the high energy and pollution-intensity of its in...

Energy - environment - security interactions
Recently energy demand in the region has reached and surpassed the 1991 level at the same time as the world oil prices have increased dramatically. Russia, for its part, has started a reappraisal of the political and eco...

Environment and security issues in Moldova
Since water resources are of particular importance to Moldova, water pollution is viewed as a nationally significant threat. Moldova does not have large lakes, and all its larger rivers originate outside its borders. the...

Nuclear energy is not a clean alternative The legacy of the Soviet Union's nuclear activities
Even though the nuclear industry does not significantly contribute to greenhouse gas emissions, it is a disputable alternative to fossil fuels. In the former USSR people and the environment still have to cope with the ...

Energy cost of various construction materials
CO2 emissions are not directly deducible from energy costs. Concrete for instance is a very CO2-intensive material due to the emissions from chemical processes involved in its production, despite the relatively low energ...

Strategic options for climate change mitigation Global cost curve for greenhouse gas abatement measures
This graphic attempts to show 'all in one': the various measures for greenhouse gas reduction with both reduction (in CO2 equivalent) and cost (in Euros) quantified. Read from left to right it gives the whole range of s...

Some examples of the effect of individual behaviour on greenhouse gas emissions in France
The area of the squares is proportionate to the annual reduction in emissions in million tonnes of CO2 equivalent. Estimated values calculated by France's Environment Institute (Ifen), drawing on various sources: Mani...
