    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

    Decentralized governance of natural resources is considered one of the key strategies for promoting sustainable
    management of natural resources at local level. Effective decentralized natural resource management requires
    strong local natural resource institutions. Therefore, strengthening local institutions governing the management
    of natural resources is one of the core principles of decentralization reforms in Francophone West Africa
    countries. This study assessed the existing local institutions (rules, norms and or local conventions) governing

    This paper argues and provides empirical evidence that trade-offs and/or complementarities are
    inherent in technological options that shape the adoption of and land-use decisions in production
    systems involving multiple crops in Ethiopia. By applying a fractional response model to a
    nationally representative sample of 1 469 households, this paper found that, while there are tradeoffs
    in the land-use decisions regarding barley and potatoes, there are complementarities in the

    Wildlife populations are declining severely in many protected areas and unprotected pastoral areas of Africa.
    Rapid large-scale land use changes, poaching, climate change, rising population pressures, governance, policy, economic
    and socio-cultural transformations and competition with livestock all contribute to the declines in abundance. Here we
    analyze the population dynamics of 15 wildlife and four livestock species monitored using aerial surveys from 1977 to

    A tragedy of the commons is unfolding in the rangelands of West Asia and North Africa (WANA), where land is either public or collectively owned. Overgrazing under this land tenure has led to severe land degradation and soil erosion. Poverty and environmental degradation are intertwined in this low-rainfall region, where more than 38 million people live in rural areas and depend mainly on agriculture. Traditional rangeland grazing provides fodder in winter and spring, while in summer and autumn the animals browse cereal stubble and other crop residues.

    ICARDA continued to play a critical role in the development, improvement, and dissemination of climate-resilient crop varieties last year. The varieties strengthened food and nutritional security and provided a critical defense against extreme temperatures, water scarcity, and the emergence of new pests and diseases.

    Tunisie, Afrique septentrionale

    This summary describes the work of the LADA (Land Degradation and Assessment in Dry Areas) project that identifies and describes geographical areas suffering from land degradation in the governorates of Tunisia. Through a comparative study of these areas, it identifies the failures and successes in national efforts to combat land degradation and, therefore, build local community capacity to resist climate change. It is intended for policymakers, donors and other partners and supporters.

    In Moroccan oases, date palm agricultural operations are mainly
    manual and seldom implemented, contributing to palm grove
    degradation.
    The introduction of small mechanization may reduce
    drudgery, encourage/attract youths, increase labor
    productivity and safety.
