    A large number of vegetation indices have been developed and widely applied
    in terrestrial ecosystem research in the recent decades. However, a certain limitation was
    observed while applying these indices in research in dry areas due to their low sensitivity
    to low vegetation cover. In this context, the objectives of this study are to develop a new
    vegetation index, namely, the Generalized Difference Vegetation Index (GDVI), and to
    examine its applicability to the assessment of dryland environment. Based on the field

    The goals of this review are to: (i) identify options with proven success and high potential for up-scaling in Ethiopian drylands, (ii) analyze factors underlying relative success in different agro-ecologies and under different institutional conditions, and (iii) assess options that may have high potential in areas and systems without well proven successful options.

    Nomadic pastoralism is a precarious lifestyle and a significant form of land use involving some form of mobility within extensive rangeland areas (WISP, 2007). Pastoralism provides 10% of the world’s meat production and supports approximately 200 million households worldwide (FAO, 2001). A declining trend in pastoralism with a shift to sedentary agro-pastoral practices on smaller tracks of land and its major implications on rangeland management have been noted by the authors across many regions.

    Agro-ecosystems in dry areas are sensitive to changes in climate and land use. The productivities of these agro-ecosystems are highly variable in both spatial and temporal scales. Accurate and up-to-date information on these production systems at farmscape to landscape scales are important for understanding the food security

    Land degradation resulting from improper land use and management is a major cause of declined productivity
    in the arid environment. The objectives of this study were to examine the effects of a sequence of land use changes,
    soil conservation measures, and the time since their implementation on the degradation of selected soil properties.
    The climate for the selected 105 km2 watershed varies from semi-arid sub-tropical to Mediterranean sub-humid. Land
