    Kenya

    This study was conducted in the northern part of Kenya, in Kakuma division, Turkana district. Kakuma is a semi-
    arid area under nomadic pastoralism as the main activity. The presence of a refugee camp has attracted many people from within
    the Turkana community and also the outside community. The study aimed at documenting the effects of emergent land use
    changes on vegetation resources and the socio-economic environment in Kakuma. Data on vegetation density and cover was

    Kenya

    Two seasons of archaeological site reconnaissance and geo-archaeological fieldwork in the Kipsing and Tol river valleys of central Kenya have resulted in (1) the location of 58 surface sites and 13 spot finds and (2) the excavation and dating of 11 alluvial stratigraphic profiles. These data are incorporated with our previous work in the study area to yield a preliminary interpretation of Middle and Later Stone Age tool technologies and land-use strategies during the Late Pleistocene period there.

    Afrique

    This report is the first in a series of research studies that the Economic Commission for Africa (ECA) will produce with a view to improving the understanding of the links between land tenure systems and sustainable development in Africa. In a continent where 80 percent of the population relies on agriculture for their livelihood, the formulation and implementation of appropriate land policies is a paramount factor in poverty reduction strategies. Research is therefore needed to help policymakers take learned decisions when addressing land tenure issues.

    Parasitic nematodes, especially
    Haemonchus contortus,
    are among the most common and
    economically important causes of infectious
    diseases of sheep and goats owned by
    pastoralists and small holder farm
    ers in East Africa. In Kenya, control of these infections
    mainly relies on the use of anthelmintic dr
    ugs. However, ethnoveteri
    nary medicine (EVM)
    preparations are widely used by pastoralists
    and small holder farmers (SHF) for treatment
    of their livestock agains

    Afrique du Sud

    This is the first report to be issued by the SACN on the ‘State of South African Cities’. The report takes a hard look at the forces that have transformed the country’s largest cities over the decade since 1994 and asks, if the current trends continue, whether cities can expect positive or negative things in the years to come. As part of the process of celebrating 10 years of democracy, the Office of the President has led a ‘Ten Year Review’ to assess what has been achieved over the last decade, and to define the strategic challenges for the future.

    Brésil

    The vegetation cover plays a key role in protection and conservation of natural resources, particularly concerning soils. This study had as objective to analyze space and time dimensions of anthropic influence on the vegetation cover in part of the semi-arid region of the Ceará State, Brazil. LANDSAT TM-5 satellite images of 1985 and 1994 combined with geoprocessing techniques were used to verify the hypothesis of intensification of environmental degradation. Maps of the vegetation cover, land use, soils, and hydrography were elaborated.

    Costa Rica

    We summarize existing theoretical claims linking poverty to rates of deforestation and then examine this linkage empirically for Costa Rica during the 20th century using an econometric approach that addresses the irreversibilities in deforestation. Our data facilitate an empirical analysis of the implications for deforestation of where the poor live. Without controlling for this, impacts of poverty per se are confounded by richer areas being different from the areas inhabited by the poor, who we expect to find on more marginal lands, for instance less profitable lands.
