    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.

    To help break the cycle of poverty, improve food and nutritional security, halt or reverse the alarming process of resource degradation in the dry areas, and help communities adapt to the impacts of climate variability and change, ICARDA’s Strategic Plan 2017-2026 outlines our research and organizational approach for action to achieve our vision of thriving and resilient communities in the dry areas of the developing world.

    Land degradation and desertification are among the biggest environmental challenges of our time. In the last 40 years, we lost nearly a third of the world’s arable farmland due to erosion, just as the number of people to be fed from it almost doubled. That’s why the UN General Assembly declared 2015 as the International Year of Soils. And the good news is that this new report shows that while Africa remains the most severely a«ected region, the benefit of taking action across the continent outweighs the cost of implementing it: not just by a little, but by a factor of seven.

    Soil erosion and deposition values were estimated using pixel based landscape information and the Unit Stream Power Erosion Deposition (USPED) model, which works with the Universal Soil Loss Equation (USLE) parameters. The USPED model was adapted to Ethiopian conditions based on evidence from the Soil Conservation Research Programme, and calibrated and validated using data from former research stations as well as the Abbay (Blue Nile) Basin. Additionally, some of the USLE parameters were reduced in order to achieve a satisfactory approximation of sediment loss for the Abbay Basin.

    A system dynamics approach was used to determine the sustainable stocking rate of the Menz sheep population in the Ethiopian highland. A model was developed to simulate stocking rate based on communal grazing land. The model is weather and resource (feed supply) driven. Pasture growth and dynamics was modeled using rainfall and temperature data. Herd dynamics was based on age groups of male and female animals from birth to herd exit, taking production and reproduction parameters into account.

    The Second United Nations Regional Cartographic Conference for Africa held at Tunis in September 1966, the Niger in association with Madagascar; presented a resolution recommending that the ECA organize a seminar on cadastre. It was hoped that such a seminar would enable the Niger to become acquainted with and compare the latest methods used by certain African countries and possibly to benefit from their experience in establishing a cadastre in the Niger.

    Of the nation's 122.2 million hectares of total area, 84.1 million hectares of land and 12.1 million hectares of water and water courses comprise the potentially productive cultivable land and water resources of the nation. At present, only 10.4 per cent of the total land area i.e. 12.9 million hectares is put under cultivation of which 9 to 91/2 million hectares have actually "been planted and harvested. Agriculture, the dominant sector of the country's economy is not only a goldmine in terms of potential but also a real source of wealth.
