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.
Self-sufficiency or surplus: Conflicting local and national rural development goals in Cambodia
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.
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).
Land administration for food security: A research synthesis
Food security remains an ongoing global concern: the challenge of ensuring food availability, access, and utility for all, at all times, is yet to be met. The body of literature relating to food security is growing immensely. Land administrators are part of the discourse. Their arguments are spread disparately across academic and professional publications. The distinction between scientific work and political rhetoric is increasingly blurry: the role of land administration needs to be more concisely articulated.
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.
