    Land conversion is often not carried out in a sustainable way. The loss of arable land and biodiversity, concern about food security and rising costs of infrastructure due to urban sprawl are just some of the problems under discussion. This paper compares Germany, China and Cambodia.

    Automobiles are a major source of CO2 emissions. Because there is no immediate technological fix to reduce these emissions, the most promising current strategy is to promote less automobile use. In the United States, this is difficult because federal programs such as the interstate highway system and local land use planning and regulation have encouraged suburban sprawl. In 2006, the state of California passed legislation to roll back greenhouse emissions to 1990 levels by 2020. This legislation did not link the roll back target with land use policies.

    This paper presents the results of a sustainability impact assessment (SIA) of policy induced land use changes in Yogyakarta, Indonesia. The regional problems include rapid expansions of urban areas, due to high population pressure, and the conversion of paddy fields and forests into settlements. The objective of this study was to assess the impacts of two land use policies on social, economic, and environmental Land Use Functions (LUFs) in Yogyakarta.

    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).
