    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 project aims to improve the productivity of degraded rangelands through efficient utilization of limited rainfall. Nearly 48% of farmers in the Muhareb community own flocks, with an average flock size of about 159 head. About 52% of farmers in Um Al Naám own flocks, with an average of 125 head; about 63% of farmers in Muhareb community own a small flock (average 28 head), or a medium flock size (30%, average 293 head), or a large flock (7%, average 751 head. However, about 72% of farmers in Um Al Naám own a small flock, with an average flock size of 36 head.

    This issue of Caravan chronicles ICARDA’s efforts in developing a research strategy and a need-based research program for the CAC region. In doing so, ICARDA played a major role in bringing together all partners, most importantly donors. The article on page 8 traces the history of this effort and provides an overview of the current status of collaboration.

    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

    Achieving cooperation in natural resource management is always
    a challenge when incentives exist for an individual to maximise her short term
    benefits at the cost of a group. We study a public good social dilemma in water
    infrastructure provision on land reform farms in Namibia. In the context of the
    Namibian land reform, arbitrarily mixed groups of livestock farmers have to share
    the operation and maintenance of water infrastructure. Typically, water is mainly
    used for livestock production, and livestock numbers are subject to high fluctuations

    Drylands are characterized by physical water scarcity, often associated with land degradation and
    desertifi cation. Other factors that contribute to these problems include high population densities,
    unwise agricultural practices and overgrazing. However, while desert ecosystems are fragile and
    vulnerable and can collapse in the short term, given the right conditions and protection, these
    areas also have a great potential for recovery. Examples of the recovery of areas have led to the

    Research on micro-catchment rainwater harvesting techniques by ICARDA and Jordanian
    scientists has led to the establishment of semicircular bunds on contour ridges and furrows
    (using GPS laser-guided Vallerani machine) and runoff strips in two communities of Jordan
    Badia. As an outcome of this research, an effective micro-catchment laser-guided system was
    identified for rainfall harvesting, which has led to improved water availability, increased
    vegetative cover and improved soil health, and provided rural communities substantial sources
