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...

The importance of small forestry enterprises in developing countries The importance of small forestry enterprises in developing countries
It is estimated that exported timber only represents 5 per cent of the wood cut in tropical forests. 10 per cent is timber used locally and the majority - 85 per cent- of wood is for fuel. While exports are generally the preserve of large scale enterprises, the domestic market is dominated by small forest enterprises. In many countries the forest sector constitutes mainly small forest enterprises - employing from 10 to 100 full-time employees. Th...

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 ...

Financial flows for developing countries Financial flows for developing countries
With increased globalization and a smaller world, money flows more easily and the flows have increased. Where aid once represented a majority of the funds from high income countries to developing countries, this has now been surpassed by investments and worker’s remittances, and these flows show no sign of slowing down – maybe pausing for an occasional downturn in the global economy. The question is when this will start show as a significant decr...

Money talks for turtles - conservation and economy Money talks for turtles - conservation and economy
Marine turtles have been used for eggs, meat, shell, oil, leather or other products for 7000 years. Modern times have introduced another way for society to profit from these species - to generate economic income as a tourism attraction. Sound turtle management relies on local communities, which – as economic incentive - should receive a fair share of the revenues. In many cases, the bulk of the revenues from the local level end up elsewhere, eve...

World poverty distribution World poverty distribution
Three-quarters of all poor people still live in rural areas. They are heavily reliant on natural resources for their livelihoods: soil, water, forests and fisheries underpin commercial and subsistence activities and often provide a safety net to the poor in times of crises. These natural resources which are abundant in many developing countries - represent an important asset and potential wealth for poor people and their communities. As many of t...

Natural resource - solar power (potential) 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 convenient, affordable energy can contribute to a household’s productivity and income generating potential, its availability can help families and communities break out of the cycle of poverty. At the same time it also provides gro...

Natural resources - minerals Natural resources - minerals
In more than hundred countries around the world, miners dig minerals and metals out of the ground, satisfying a slowly but continuously increasing demand from industrial production, agriculture, construction, high-tech sectors, and merchandise producers. In contrast to the other natural resources presented here, minerals are a finite resource, and the resource and their profits needs to be managed carefully to ensure sustained livelihoods after t...

Forests working for the global climate - Reducing Emissions from Deforestation in Developing Countries (REDD) Forests working for the global climate - Reducing Emissions from Deforestation in Developing Countries (REDD)
Carbon trading of credits from avoided deforestation could yield billions of dollars for tropical countries, according to an analysis by Rhett A.Butler, founder and editor from mongabay.com, a leading tropical forest web site. The proposed mechanism - Reducing Emissions from Deforestation in Developing Countries (REDD) - will enable these countries to maintain their forests as a global resource. Using conservative estimates on carbon storage in ...

Government revenues from diamond exports in Sierra Leone Government revenues from diamond exports in Sierra Leone
The government of Sierra Leone saw a total of USD 5.2 million (2004) in revenues from diamond related activities. This comes in the form of mining, dealer and export license fees and from export taxes. To feed some of the revenues back to poor communities, the Diamond Areas Community Development Fund (DACDF) has been set up, with an annual commitment of 25% of revenue from export taxes. The intention is that this money will be dedicated to commun...

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...

World map of forest distribution (Natural resources - forests) World map of forest distribution (Natural resources - forests)
Approximately 240 million of the world's poor that live in forested areas of developing countries depend on forests for their livelihoods. Forest and its products provide cash income, jobs, and consumption goods for poor families. Forestry provides formal and informal employment for an estimated 40-60 million people. The sector contributes in some developing countries more than eight per cent to GDP. Timber may be the most important forest produc...

Freshwater – a natural resource which has been adopted as a human right by the UN in 2002: 'the human right to water entitles everyone to sufficient; affordable; physically accessible; safe and acceptable water for personal and domestic uses'. People depend on this resource for drinking and cooking, for irrigation of farms, for hygiene and sanitation and for power generation. The map presenting this resource only focuses on one part of the geogra...

Electrification and traditional fuels in Sub-Saharan Africa 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 remaining countries exhibit low rates of electricity access and use of high quality fuels. Easy access to electricity and power increases the living standard and enables the development of additional services.

Reforestation, town of Galma and surroundings, Niger 1975 and 2003 Reforestation, town of Galma and surroundings, Niger 1975 and 2003
In 1970s and 1980s - years of environmental crisis, there were few trees remaining in Niger. Wind-blown sands razed farmers' young crops and they often had to plant crops three times to succeed. Since the middle of the 1980s in the most densely populated parts of Niger farmers have begun to protect and manage young trees and bushes regenerating on their cultivated fields. This is natural farmer-managed forest regeneration. Some trees fix nitrogen...

Greenland, showing rates of surface-elevation change between the late 1990s and 2003 Greenland, showing rates of surface-elevation change between the late 1990s and 2003
Mass-balance estimates for Greenland show thickening at high elevations since the early 1990s at rates that increased to about 4 cm per year after 2000, consistent with expectations of increasing snowfall in a warming climate. However, this mass gain is far exceeded by losses associated with large increases in thinning of the ice sheet near the coast. Total loss from the ice sheet more than doubled, from a few tens of billions of tonnes per year ...

Ecoregions in Antarctica Ecoregions in Antarctica
Antarctica represents a very unique and special case on our planet. With the richness of the Southern Ocean, the coasts and the Southern islands have relatively high biodiversity and biomass in the form of numerous sea birds - such as penguins and mammals such as seals and sea lions - primarily around the Antarctic peninsula - in the Marielandia Arctic Tundra ecoregion. In contrast - the inland of the Antarctic continent are a cold, windy and inh...

Antarctica is interesting for many types of researchers. For example, glaciologists study the ice and snow, while oceanographers look at the oceans. The ice, snow and oceans affect the global climate and are presently changing as a result of global warming. The many other types of researchers who work here include geologists (who study rocks), astronomers (who study outer space), and meteorologists (who study the weather). How do researchers stud...
