    Population, environment and agricultural development constitute an inter linked, mutually-reinforcing paradigm which affects the level of food insecurity and the depth of poverty in a developing region such as Africa. Apart from chronic food insecurity and acute poverty, Africa is faced with other daunting threats. These include escalating population growth, widespread malnutrition, inadequate sanitation, and scarcity of clean water, air pollution and severe land degradation.

    Ghana, Afrique

    In Ghana, over the years considerable amount of valuable environmental information (geospatial information included) have been collected in various forms and in different depths by government ministries, departments and agencies. A distributing feature of the availability of this information is the lack of general awareness of the existence of this valuable resource in repository agencies. Where they are known to exist, they are poorly stored or scattered in various places and mostly out of date.

    The status of cadastral and land information systems in Africa is assessed, with specific reference to their capacity to assist decision-makers. Recommendations and guidelines are provided for the adaptation of existing systems and/or the development of new systems, so that they can be used for land reform, physical planning and integrated land administration. The guidelines take into account the need to create land information for decision-makers without creating unaffordable costs to the state, given that the average per capita income for Africa in 1995 was USD665.

OSS's mission is conducted within the international framework of the Convention to Combat Desertification (CCD) and Agenda 21 and aims to favour the development and the optimisation of its African partners' information wealth, for an optimal use of the means for combating desertification.

    The informal settlements, townships, temporary camps and other human posts need at least basic services such as potable water, electricity and sanitation. Other services such as food supply, medical aid and shelters are usually arranged in case of disasters and large human migrations. A proper and efficient services need should be well estimated and simply implemented. All requirements can be achieved as results of evaluation with use of the geo information decision support system GDSS, suggesting services sorts and quantities.

    Risk and uncertainty in a water market will generate trading patterns that differ from those expected under conditions of perfect foresight. Although trades will occur based on differences in VMPs of water in both markets, they will also be generated by differences in risk. Some farmers will choose to reduce relative risk by purchasing additional water rights whereas others will hold few rights and rely on the spot market to meet their needs in dry years.

    Agriculture has recently been noted as a provider of non-market environmental benefits in addition to its traditional recognition as a source of negative externalities from polluting inputs. In this paper, a general equilibrium framework is used to determine optimal land subsidies and input taxes in agriculture. When agriculture generates both amenities and pollution, the optimal subsidy does not equal the net extra-market value of agricultural land.
