    Water scarcity and land degradation are widespread problems that affect agricultural productivity, food security and environmental quality in several parts of the world, particularly in the dry areas. Sustainable management of soil and water is necessary to optimize the use of limited rainwater for crop production and to decrease soil erosion. One management option is utilizing rainfall more efficiently through water harvesting. In arid areas, different types of water harvesting techniques (WHT) are being developed by

    The Kelka forest in the Mopti region of Mali is important for the provision of ecosystem services like carbon sequestration and maintenance of the hydrological cycle. The Kelka forest area occupies more than 300, 000 hectares with 15
    villages within and around its boundaries. The forest resources and soil fertility of the forest are in continuous decline due to a combination of climatic and human induced factors. For example, the availability of firewood has halved

    Gedaref State was previously known as the
    food basket of Sudan. Over several decades
    unsustainable agricultural practices that
    combined near-monocropping with low nutrient
    replenishment have led to significant degradation
    of soils, which are no longer able to sustain farmer
    livelihoods. This study found that adopting
    an integrated sustainable land use and forest
    restoration scenario could reverse the current
    land degradation trend. The integration of Acacia
    senegal with sorghum, Sudan’s primary staple

    Mali, Afrique occidentale

    This research was carried out in three agro-climatic regions of Mali (Mopti, Koulikoro and Sikasso) to assess
    contour bunding technology (CBT) for improved land and water management. Reference was made to
    existing literature and field surveys were conducted following georeferencing and quantification of existing
    land and water management technologies. Farmers’ perceptions towards the use of the most commonly
    applied technologies were assessed. Results indicate that CBT is widely adopted in farmers’ fields to

    Land degradation is a pressing concern that reaches
    across all republics of Central Asia and is increasingly
    affecting the economy and quality of life in each.
    The resulting loss of arable land particularly affects
    the rural poor, who depend directly on what
    the land can provide for their very survival and
    livelihoods. The breakup of the Soviet Union led to
    mass de-collectivisation of agricultural frameworks
    across Central Asia, with formerly centralised land
    management regimes dissolved. The reorganisation

    Land degradation is a serious problem, particularly on vulnerable agricultural lands to soil erosion, which
    signifies the temporary or permanent decline in the productive capacity of the land (UN/FAO definition).
    Erosion is one of the most common problems around the world. Sanders (2004) considers that erosion
    and soil degradation issues have contributed to the decline of great civilizations in Egypt, China or
    Greece. The annual costs of soil erosion in the US are estimated between US$ 30 billion and US$ 44

    The threat that the degradation of terraces in the highlands of Yemen poses to the livelihood of rural households and to national economic development has been widely recognized. The aim of this study was to contribute to the development of policy recommendations for the improvement of the life of rural families in the Yemeni mountains. Three small mountain watersheds (200-700 ha) in the northern, middle and southern mountain regions of Yemen were selected as the testing grounds for this study.

    Tunisie, Afrique septentrionale

    Many efforts have been invested in the Dry Areas to combat land degradation and desertification. Different strategies and approaches for conserving soil and water and restoring degraded lands have been developed by local, national and international agents to synergise efforts towards land degradation neutrality achievement. Tunisia is a dryland country facing a high risk of land degradation over more than 50% of its territory. It is a country with high investment programs for soil and water conservation (SWC), and large level adoption of SLM practices.
