Catches in the Mauritania Exclusive Economic Zone (EEZ) 1950-2002 Catches in the Mauritania Exclusive Economic Zone (EEZ) 1950-2002
Marine fisheries represent a significant, but finite, natural resource for coastal countries. For some countries like Mauritania, the majority of the catches belong to international fleets. This represents a significant income for the country in question, but at the same time oppurtunities for value-added services and domestic employment are lost.

Nigeria and the freshwater challenge Nigeria and the freshwater challenge
Out of the total precipitation reaching Nigeria, it can be separated into green and blue water. Green water (79% of the precipitation) represents the fraction of rainfall that generates soil moisture and which supports terrestrial ecosystems. It is not returned to groundwater and rivers, but will eventually evaporate or transpire through plants. Blue water, on the other hand, represents the fraction (21%) of the precipitation that runs into river...

Coastal issues in the islands of Comoros and Mayotte Coastal issues in the islands of Comoros and Mayotte
With poverty and high population density this group of volcanic islands between Eastern Africa and Madagascar faces challenges in the management of the coastal environment. The islands are fringed by magnificent coral reefs, and the waters houses the rare coelacanth fish. Among the responses there have been initiatives to encourage ecotourism and the support in establishing the 400 km2 Mohéli Marine Park.

Woodfuel and energy consumption 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 estimate that this will further increase, together with population increase and higher energy needs. In total energy consumption, populous countries, such as Nigeria, South Africa and Egypt have the highest totals.

Current and potential arable land use in Africa Current and potential arable land use in Africa
Out of the total land area in Africa, only a fraction is used for arable land. Using soil, land cover and climatic characteristics a FAO study has estimated the potential land area for rainfed crops, excluding built up areas and forests – neither of which would be available for agriculture. According to the study, the potential – if realised – would mean an increase ranging from 150 – 700% percent per region, with a total potential for the whole ...

Catches in the Mauritania Exclusive Economic Zone (EEZ) 1950-2002 Catches in the Mauritania Exclusive Economic Zone (EEZ) 1950-2002
Marine fisheries represent a significant, but finite, natural resource for coastal countries. The majority of the catches in some of the areas of the coast are not primarily by the coastal countries, but rather as in this example, where countries from Europe and Asia (Japan and South Korea are in the ‘others’ group) represent the majority. According to this estimation Mauritania only landed about 10% of the total catch in 2002, with Netherlands a...

Agriculture in Africa, value added out of GDP Agriculture in Africa, value added out of GDP
For the future of Africa, agriculture remains one of the most important issues. A majority of the population, especially outside urban areas, are involved in agriculture, and food security is one of the most important issues to solve in the short term in some parts of the region. The current financial importance varies, as presented in this map, with agriculture representing up to 50-60% of the total economy in some countries (Guinea-Bissau, Cent...

Gender equality and empowerment of women: eliminate differences in education Gender equality and empowerment of women: eliminate differences in education
In increasing living standards, sustainability and livelihoods and eliminating poverty, gender equality and education are seen as some of the main means. This is further recognized in the Millennium Development Goals, as goal 3: 'Promote gender equality and empower women'. This map illustrates one of the indicators for indicator 9 (target 4) under this goal, and the Millennium Project assesses the current progress in reaching the goal as good for...

Africa: Stockholm convention on persistent organic pollutants (POPs) Africa: Stockholm convention on persistent organic pollutants (POPs)
The process initiated by UNEP in 1995, materialised as the Stockholm convention in May 2001. The convention bans chemicals such as chlordane, DDT and PCB and other organic pesticides and industrial chemicals, as well as establishing precautionary approaches for the future. Most African countries are using agents, such as DDT, for control of disease vectors and pests under exemptions.

Loss of Great Ape habitat 2002-2032 (Africa) Loss of Great Ape habitat 2002-2032 (Africa)
Based on population pressures the GLOBIO2 model has assessed the current and future human impacts on Great Ape habitat in Africa (Chimpanzee, Bonobo and Gorilla). The analysis shows a vast reduction of some of the world's remaining wilderness areas. (this poster prepared for the UNESCO GRASP meeting in November 2003)

Sub-Saharan Africa: Mineral resources and political instability Sub-Saharan Africa: Mineral resources and political instability
Africa, south of Sahara, is a region with plenty of valuable mineral resources - metals, oil and diamonds. Foreign investments lead the extraction and exploration in many of these places to supply the world markets. This region is also the site of several open conflicts, recent and trying peace and political instability. Foreign armed forces are present in military bases and peace keeping forces.

Population and growth, projections and historic data Population and growth, projections and historic data
The population has rapidly increased in Africa, to reach approximately 905 million inhabitants by 2005. The rate of the annual growth is levelling out after seeing a peak around 1990. Out of the sub-regions, the population is fairly evenly distributed, as indicated in the pie-chart, with Central Africa trailing behind the others, and the Western Indian Ocean islands with the smallest share out of the total population.

Invasive alien plants in South Africa Invasive alien plants in South Africa
Species that has been introduced on purpose or spread in the wild threaten livelihoods in agriculture or water resources. As illustrated in this map, some regions of South Africa have very high ratios of invasive alien plants and are subject to government projects to limit the distribution and information campaigns informing the public.

Africa: policy on genetically modified organisms (GMO) and genetically engineered (GE) foods Africa: policy on genetically modified organisms (GMO) and genetically engineered (GE) foods
The Cartagena protocol on biosafety, a supplement to the convention on biological diversity, has strong support in Africa, with a majority of the countries as signatories. In addition, several countries have, in the past, rejected aid (especially unmilled grains) in food imports with concerns for national biosafety. South Africa is so far the only country that is seeing wide-spread use of genetically modified crops.

Emissions of carbon dioxide, in Africa and selected OECD countries Emissions of carbon dioxide, in Africa and selected OECD countries
Africa represents only a small fraction, 3.6%, out of the total carbon dioxide (CO2) emissions per year, yet 14% of the population of the world lives here. The emissions per inhabitant in Libya, the Seychelles and South Africa are on the level of the lowest among OECD countries with the other African countries trailing lower behind them. Regionally, emissions (both per capita and in total) are at their highest in North Africa and in the country o...

Pesticides stockpiles in Africa Pesticides stockpiles in Africa
Mountains of obsolete pesticides are stockpiled in Africa. Problems with labelling, storage, and the supply of unsuitable products, means that they sit around unused, some for as long as 40 years. They include poisons long ago banned (e.g. DDT, aldrin, dieldrin, chlordane, heptachlor, and others). In some cases the pesticides have leaked from damaged containers. Unable to dispose of them safely the likelihood is that the piles will continue to gr...
