    The paper deals with analyses and propositions for adaptive governance of an alpine (A) and an Ethiopian (B) agropastoral system with common-pool pastures. Sustainability can be enhanced by augmenting (i) the ecological and social capitals in relation to costs and (ii) the resilience or adaptive capacity. In (A), a multifunctional agriculture appears to maintain the ecological capital providing many ecosystem services. In (B), the ecological capital can be increased by reversing the trend towards land degradation.

    Land degradation is recognized as one of the major threats to the buffer zones of protected areas (PAs) in Vietnam. In particular, the expansion of land degradation into the PAs is exerting pressure on biodiversity conservation efforts. This degradation is partially the result of mismanagement: the utilization of the land is often unmatched with the inherent suitability of the land. Identification of the spatial distribution of suitable areas for cropland is essential for sustainable land-use recommendation.

    In recent years it has become clear that climate change is an inevitable process. In Sub-Saharan Africa, the expectation is that climate change will have an especially negative impact, not only a result of projected warming and rainfall deficits, but also because of the vulnerability of the population. The impact upon food security will be of great significance, and may be defined as being composed of three components: availability, access, and utilization.

    This study examined environmental and socioeconomic outcomes of a water project in rural Bolivia, and sought insights on how and why its planning was so flawed. The project destroyed an ancient, sustainable irrigation system, and replaced it with one that provides insufficient and diminishing quantities of water to many fewer people, appears to be causing land degradation and groundwater depletion, and has fueled conflicts.

    This research explores the intersection between the various federal and state forestry incentive programs and the adoption of sustainable forestry practices on non-industrial private forest (NIPF) lands in the US. The qualitative research reported here draws upon a series of eight focus groups of NIPF landowners (two each in Minnesota, Oregon, Pennsylvania, and South Carolina).

    This paper explains regionally differentiated patterns of structural change based on a theoretical framework dealing with strategic interaction of farms on the land market. The main research question focuses on the causes of regionally persistent structures. An empirical Markov chain model is defined for the West German agricultural sector. Thereby it is possible to explain the probabilities of farm growth, decline or exit in terms of the current and former regional farm size structure.

    Established in 1994, the United Nations to Combat Desertification (UNCCD) is the sole legally binding international agreement linking environment and development to sustainable land management. The Convention addresses specifically the arid, semi-arid and dry sub-humid areas, known as the drylands, where some of the most vulnerable ecosystems and peoples can be found.

    The Kyoto Protocol negotiated in the mid-1990s to address climate change adaptation and mitigation will be replaced by a post-Kyoto agreement in 2012. The new agreement under negotiation needs to seal the policy gaps in adaptation and mitigation that were omitted or excluded from Kyoto on account of scientific uncertainties. Particular attention needs to be given to the potential of land in all its dimensions considering its high capacity to store carbon. Land stores twice as much organic carbon as vegetation and the atmosphere combined.

    Almost all societies acknowledge the concept of state or public landownership in which property rights are vested in a public body on a national, regional or community level. State and public land tenure arrangements define rules for the distribution, use and protection of publicly vested lands. State lands may be used to deliver public services. Authorities or customary rulers may act as custodians of common property resources or of environmentally or culturally sensitive sites on behalf of society. Many forms of public tenure arrangements have been introduced.

    Many drylands in the world suffer problems of land degradation and desertification derived from human activities and exacerbated by drought. Too often these degradation processes have been endured by the ecosystems for a long time, and, according to forecasts of climate change, are likely to worsen in the future. Ecological restoration combined with adaptive management can be effective tools in response to this environmental and socioeconomic problem.
