    Along with economic growth and improved living standards, waste from households, industries, and commercial or service establishments is expected to increase rapidly over the next years. Managing this waste is a hard challenge for the Government of Vietnam because of its substantial cost and lack of awareness and participation of people and businesses. Wastes can be classified according to: their form (wastewater, solid waste); their origin (industrial wastes, agricultural wastes, urban (municipal) wastes); and their hazardous nature (non-hazardous or hazardous).

    Literatures about factors affecting demand scale of rural land circulation are reviewed. Based on this, a total of 5 deficiencies in these literatures are put forward, which are the inconsistency between model selection and sample data type in some literatures, the lack of analysis from the perspective of internal family, the incomplete or inaccurate research factors, the lack of analysis on causation, and the mixture of inflow and outflow of land circulation.

    The emerging biofuel sector has drawn great interest as an alternative source of fuel for transportation. The expansion of biofuels greatly impacts world agricultural markets, since currently, the primary feedstocks for ethanol and biodiesel production are field crops and their derived products. There is great interest in the potential of countries to expand their biofuel sectors through increased production of feedstocks. The long-term potential for developing first-generation biofuels in many countries depends on a large and constant supply of feedstocks.

    China’s economic reforms make the farmers face the risk of land reallocation and adjustment, raising the questions about the impact of land reallocation on farm productivity and efficiency. Deep understanding what determines land reallocation, whether and to what extent farm productivity and efficiency are affected by the frequency of land reallocation could help policy makers introduce better targeted rural development policies.

    This paper summarizes the regional situation of Henan Province of China, and introduces the principle of ecological footprint mode, as well as computing formulas of ecological footprint and ecological capacity. According to the related data of Henan Province from 1998 to 2007, this paper firstly calculates the per capita ecological footprint and per capita ecological capacity of Henan Province. Result indicates that cultivated land in Henan Province shows ecological surplus with sustainable land use. And ecological surplus has increased since the year 2003.

    This study was carried out to determine the impacts of climate change on aridity and land cover in Turkey. Data for future (2070s) climate change, according to present conditions (1990s), were estimated from the prediction results of a regional climate model (RCM). The RCM, which was developed in Japan, is based on the MRI model. The potential impacts of climate change were estimated according to the A2 scenario of Special Report on Emissions Scenarios (SRES).

    Understanding farmer decisions on land use conversions (LUC) in rural areas has significant importance to understand and predict the patterns of land use changes in China. Many methods have been developed to search for the influencing factors on land use changes at farm household level. However, these methods have difficulty in evaluating the intertwined influences between factors and achieving farmer decision rules on LUC.

    The Pearl River Delta (PRD) region in southern China has experienced rapid urbanization and dramatic economic growth in last 25 years. Using identical observed meteorology for lateral boundary conditions, two one-month simulations were conducted: one using the original United States Geological Survey (USGS) 24-category land cover data (namely NU) and the other using the urban land cover data from 2004 Moderate Resolution Imaging Spectroradiometer (MODIS) satellite images (namely HU) as lower boundary conditions in a mesoscale model.

    1. China's Grain for Green Project is a rapid landscape-scale shift in ground cover and land use with significant implications for biodiversity. From 1998 to 2005, we carried out field studies to examine the landscape-level impacts of this project, and to provide a practical example of the successes and failures of a large-scale attempt to restore a vulnerable environment. 2. In a northern part of China's Shaanxi Province, our results indicated that the total vegetation cover in areas covered by this project increased from 29·7% in 1998 to 42·2% in 2005.
