    Cambodge

    Cambodia has recently demonstrated one of the highest rates of deforestation in the world. While scholars have long explored the drivers of tropical forest loss, the case of Cambodia offers particular insights into the role of the state where transnational governance and regional integration are increasingly the norm. Given the significant role logging rents play in Cambodia’s post-conflict state formation, this article explores the contemporary regime and its ongoing codependent relationship with forested land.

    This essay explores the changing landscape of food sovereignty politics in the shadow of the so-called ‘land grab’. While the food sovereignty movement emerged within a global agrarian crisis conjuncture triggered by northern dumping of foodstuffs, institutionalized in WTO trade rules, the twenty-first-century food, energy and financial crises intensify this crisis for the world’s rural poor (inflating prices of staple foods and agri-inputs) deepening the process of dispossession.

    Smallholder farmers who grow diverse landraces in centres of crop diversity contribute to sustaining the capacity of agricultural and food systems to adapt to change by maintaining crop evolution in their fields today, thus enabling humanity to continue to have the broad genetic variation needed to adapt crops to changes tomorrow. Given this fact, the last 20 years have witnessed an ever-growing interest in on-farm conservation of crop infra-specific diversity.

    The Shangri-La County of the Yunnan Province, SW China, is an economically and ecologically important area. This is especially true for Jiantang that is famous for the Napahai, Bitahai and Shudu Lake wetlands. However, continuing development has threatened the wetland ecosystems and the associated biodiversity in these areas. To better document such changes in land use and their effect on the ecosystem, land use was mapped using a time series of satellite images acquired in 1974, 1993, 2000 and 2012. The results of this survey suggest that forest cover first decreased and then increased.

    We describe a bio-economic model for Nassella neesiana (Chilean needle grass) that estimates the net benefit of a containment programme for the weed in Canterbury as the difference between the cost of containment and the costs incurred over time should the weed spread within sheep and beef pastoral systems. Logistic spread is assumed with the maximum area that could be invaded (772,080 ha) determined by constraining a climate niche model for the weed to susceptible farm system types within productive land use capability classes.

    Human activities influence the biodiversity of Mediterranean ecosystems and are involved in the transformation of natural habitats into farmland. We surveyed birds using the point count method on 288 plots at a 50-m radius in three altitudinal landscapes with different rural character in spring and autumn. The results showed that bird species richness in the study area was high (74 species). High total species richness was found in the upland rural landscape characterized by mixed land use and high landscape diversity.

    Grassland ecological migration project is implemented in Northwest China as an attempt to restore the deteriorative ecosystems. People are relocated from uninhabitable areas to immigrant areas, resulting in land use changes, which would significantly impact the ecological environment. Therefore, it urgently needs quantitative evaluation and analysis of the trends of ecological change in these immigrant areas. We selected Luanjingtan, which is the largest ecological immigrant area in Alxa, Inner Mongolia, as our case.

    Forests play an important role in the community’s livelihood, and this role has created an important relationship or mutual dependence between the forest and the community. Therefore, this study was conducted to identify the types of community’s forest dependency and to identify the effects of community’s forest dependency towards forest resources and wildlife abundance. The data were collected using the self-administered questionnaire, involving 204 community members in Bau District, Sarawak.

    Detailed and accurate land cover data are widely used for various purposes, such as global land use change detection. This study aimed to investigate Australian land use and cover change by using 774 Landsat scenes in 2000 and 2010. The reference data included pictures or high-resolution images from Google Earth, global land cover data, Shuttle Radar Topography Mission data, and other literature.
