Cambodia is currently experiencing profound processes of rural change, driven by an emerging trend of large-scale land deals. This article discusses potential future pathways by analyzing two contrasting visions and realities of land use: the aim of the governmental elites to foster surplus-producing rural areas for overall economic growth, employment creation and ultimately poverty reduction, and the attempts of smallholders to maintain and create livelihoods based on largely self-sufficient rural systems.
Trajectories of deforestation, coffee expansion and displacement of shifting cultivation in the Central Highlands of Vietnam
Production of commodities for global markets is an increasingly important factor of tropical deforestation, taking over smallholders subsistence farming. Measures to reduce deforestation and convert shifting cultivation systems towards permanent crops have recently been strengthened in several countries. But these changes have variable environmental and social impacts, including on ethnic minorities. In Vietnam, although a forest transition - i.e.
Land-cover changes of biome transition zones in Loess Plateau of China
The Holdridge life zone (HLZ) model has been improved to help classify the biome transition zone (BTZ) in China's Loess Plateau. A positive and negative transformation index of land-cover (PNTIL) was developed to quantitatively evaluate the land-cover changes in every type of BTZ. Three bioclimatic datasets, with a spatial resolution of 1km×1km, were used to classify the BTZ type in Loess Plateau. These include the mean annual biotemperature (MAB), average total annual precipitation (TAP) and potential evapotranspiration ratio (PER).
Key variables for the identification of soil management classes in the aeolian landscapes of north–west Europe
At present, spatially very detailed data sets can be obtained about soil, landscape and crop variability. However, there is a need to select independent key properties to identify management classes needed for precise land management. In a previous study performed in the European loess belt, topsoil pH, apparent electrical conductivity (ECa) and elevation were identified as key properties. In this study we enlarged the number of soil properties by including gamma ray measurements and employed a similar methodology to a field in the sand belt of northern Europe.
Death of a planning department: Challenges for regionalism in a weak mandate state
Advocates have long claimed that a regional land use planning approach achieves gains in equity, efficiency, and environmental protect, but few studies have empirically tested these claims. In this case study of a regional planning process in a weak mandate state, we find that the regional plan would have produced better land use outcomes, but its impact was severely limited by political conflicts at the county level, a recession that necessitated cuts to non-mandated services, and a lack of state leadership around regional planning.
