    ICARDA has long-standing outreach programs in North Africa, the Nile Valley, and the Red Sea region (Fig 2). In its current strategic plan, the Center will extend its work to the drylands of Sub-Saharan Africa.

    The present document consists of the official Agenda for the Options by Context Training, held in Kenya, 25-29 May 2015. The event aimed to:
    1. Familiarise all ICRAF DryDev staff with the OxC, R in D and planned comparisons approaches being used.
    2. Test and revise processes for implementing the approaches.
    3. Plan how the methods will be taken 'to scale' in each country.
    4. Produce OxC matrices and planned comparison designs for Kenyan sites.

    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

    Ethiopia has great agricultural potential as it has vast area of fertile land, diverse climate, sufficient annual rainfall, & abundant labor force. However, the current performance of agric. is far below the potential, partly due to soil erosion & land degradation, lack of using improved technologies, lack of supportive services, poor socioeconomic infrastructure, & many more interrelated socioeconomic factors. Consequently, food insecurity & poverty have remained common features in the rural community.

    África oriental, Kenya

    Drylands cover over 40% of the earth's surface and support over 2 billion people, globally (Millennium Ecosystem Assessment, 2005). In East Africa alone, over 250 million people depend on drylands for their livelihoods (De Leeuw et al., 2014) and in Kenya, 70% of the total land area is classified as arid- and semi-arid (Batjes, 2004). Over the last several decades, an increasing and more sedentary human population has resulted in more pressure on these lands, and an expansion of agricultural production into marginal dryland areas that were traditionally rangelands.

    Biodiversity in rangelands is decreasing, due to intense utilization
    for livestock production and conversion of rangeland into cropland;
    yet the outlook of rangeland biodiversity has not been
    considered in view of future global demand for food. Here we
    assess the impact of future livestock production on the global
    rangelands area and their biodiversity. First we formalized existing
    knowledge about livestock grazing impacts on biodiversity,
    expressed in mean species abundance (MSA) of the original

    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

    This issue of Caravan describes the new program, and some of the research innovations it will build on. The issue begins with two ‘opinion pieces’ by scientists from partner organizations in the CRP. They share lessons learnt from past successes (and failures), and ideas that could be applied to dryland

    This issue of Caravan showcases some of ICARDA’s efforts of coping with climate change in dry areas with improved water land management and resilient production systems. These include initiatives in conservation agriculture which provide sustained production levels while conserving the ecosystems on which our entire food system is dependent upon. ICARDA continues to make significant contributions in the promotion of sustainable water land management approaches and technologies devised by researchers and farmers.
