    Most adoption studies have employed cross-sectional data in a static discrete choice modellingframework to analyze why some farmers adopt at a certain point in time. The static approachdoes not consider the dynamic environment in which the adoption decision is made and thusdoes not incorporate the speed of adoption and the effect of time-dependent elements inexplaining adoption.

    Many developing countries are currently experiencing a rapid expansion of supermarkets. New supermarket procurement systems could have important implications for farming and wider rural development. While previous studies have analyzed farm profit and income effects, possible employment effects have received much less attention. Building on data from a recent survey of vegetable farmers in Kenya, in this article a double-hurdle model of hired labor use is developed and estimated.

    It would appear that the English common law was grafted onto Ghanaian communal societies without taking into account the differences between the early nineteenth-century capitalist economic structures and the egalitarian communal institutions of Ghana. Both systems of law reflect distinctively different economic structures. That oversight laid the foundations for the conflicts between the customary law and practice and the Anglo-American common law, its notions and conceptions of tenure.

    Regardless of the definition of the informal sector, there is wide spread consensus that the sector is important to the developing world. The International Lab-our Organization estimated that in 1990, 21 percent of the Sub-Saharan Africa's 227 million labour force was working in the informal economy. As the informal sector continued to grow both in urban and rural areas, there was a decline or stagnation in the growth of formal employment.

    There have been major shifts/changes in land use patterns in Rwanda over the past twelve years. A few striking observations include: As a percentage of total farmland, cultivated land increased. The increase in cultivated land occurred at the expense of pasture and fallow and woodlot. The share of pasture and fallow decreased from 22% in 1990 to 14% in 2002 and woodlot decreased from 11% in 1990 to 7% in 2002. This trend of increasing cultivated land is apparent from the mid-eighties to today.

    The impact of land use changes on sustainable development is of increasing interest in many regions of the world. This study aimed to test the transferability of the Framework for Participatory Impact Assessment (FoPIA), which was originally developed in the European context, to developing countries, in which lack of data often prevents the use of data-driven impact assessment methods. The core aspect of FoPIA is the stakeholder-based assessment of alternative land use scenarios.

    Although there is broad agreement that well functioning land rental markets will play an important role to increase productivity and household welfare as agrarian economies develop, evidence from Africa on the actual performance and impact of such markets is limited. We use data from Uganda to test for differences in the performance of rental, as compared to sales markets and their evolution over time, based on a framework where markets are affected by differences in ability and imperfections in rural labor and capital markets.

    The Ethiopian Rift Valley is a dry land zone where for a long time pastoral communities have made their living from acacia-based woodlands. But many pastoralists have changed from a pastoral way of life to mixed farming over time. The aim of this study was to evaluate land-use and land cover (LULC) changes in the Central Rift Valley dry lands of Ethiopia, and determine the role of drought vulnerability as a driver. A combination of GIS/remote sensing techniques, drought vulnerability analyses, field observation and surveying were employed.

    This study investigated whether the current lateral boundary for estuaries in South Africa, i.e. the estuarine functional zone (EFZ), includes all estuarine habitats. The EFZ covers 173 930 ha in 304 estuaries/outlets nationally. Field surveys and analysis of available aerial images showed that 82 (12 956.70 ha) of these estuaries (26%) had estuarine habitats occurring outside of this boundary. As a result of mapping scale, the National Vegetation Map does not represent habitats that are associated with small estuaries (approximately 50% of South Africa's estuaries).

    While the decrease in flow is obvious in the Kikuletwa River, the mechanism leading to the decrease is unclear. We assessed the influence of vegetation cover change on dry season flow in the Kikuletwa River. The combined cover of closed and open forests decreased by 68% while closed and open forests decreased by 56% and 64% respectively. Land under agroforestry decreased by 25%, while that under annual crops increased by 41%. Grasslands increased by 116% and riverine vegetation decreased by 53%.
