    Soil indicators may be used for assessing both land
    suitability for restoration and the effectiveness of restoration
    strategies in restoring ecosystem functioning and services. In
    this review paper, several soil indicators, which can be used
    to assess the effectiveness of ecological restoration strategies
    in dryland ecosystems at different spatial and temporal
    scales, are discussed. The selected indicators represent the
    different viewpoints of pedology, ecology, hydrology, and
    land management. Two overall outcomes stem from the review.

    Namibie, Afrique australe

    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

    The Economics of Land Degradation (ELD) initiative seeks to develop a science basis for policy actions to address land degradation. The purpose of this chapter is to provide with a conceptual framework and sound and feasible methodological standards for ELD assessments at global and national levels. Only if some basic standards are identified and adhered to, comparative assessments can be conducted between countries and useful aggregation of findings, based on these case studies, can be achieved.

    Soil organic carbon (SOC) and rainfall are generally
    positively related, whereas a negative relationship
    between soil inorganic carbon (SIC) and rainfall with
    some exception is observed. Land use pattern in black
    soil region (BSR) of the semi-arid tropical (SAT)
    India, consists of 80% under agriculture, followed by
    forest, horticulture, wasteland and permanent fallow.
    For sustainable agriculture on these soils, there is a
    concern about their low OC status, which warrants
    fresh initiatives to enhance their OC status by suitable

    Jordanie, Asie occidentale

    The dry rangelands of West Asia and North Africa are fragile and severely degraded due to low rainfall and mismanagement of natural resources. Rainwater harvesting (RWH) interventions are used to increase soil moisture content, vegetation cover, and productivity. However, adoption of rainwater harvesting by communities is slow. To understand adoption constraints and to develop options for sustainable integration of rainwater harvesting, a benchmark watershed was established in the dry rangelands of Jordan.

    Cropland abandonment is globally widespread and has strong repercussions for regional
    food security and the environment. Statistics suggest that one of the hotspots of abandoned cropland
    is located in the drylands of the Aral Sea Basin (ASB), which covers parts of post-Soviet Central Asia,
    Afghanistan and Iran. To date, the exact spatial and temporal extents of abandoned cropland remain
    unclear, which hampers land-use planning. Abandoned land is a potentially valuable resource for

    Stream and riparian health is a major concern for state and federal land management agencies that are charged with oversight of extensive land holdings in the mountain west of the United States. Several federal agencies in the 1980s and 1990s determined that livestock grazing had adversely impacted a majority of federal lands in this region. In response, management was changed on grazing allotments to focus on stream system health.
