    The economic and land use consequences of US biofuel programs and their contributions to GHG emissions have been the focal point of many debates and research studies in recent years. However, most of these studies focused on the land use emissions due to the first generation of biofuels such as corn ethanol, sugarcane ethanol, and biodiesel (e.g. [1, 2] [3, 4]). A quick literature review indicates that only a few attempts have been made to estimate these emissions for the second generation of biofuels which convert cellulosic materials into liquid fuels.

    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 focuses on factors influencing grassland lease, which will contribute to the heated debate about land use in China by extending to more extensive and vulnerable grassland regions. Based on review of grassland institutional change and analysis of data from 12 villages, this paper examines the impact of variables such as grassland property rights, grazing policies and physical attributes of actors on grassland lease.

    Section I challenges Schultz's assertions: (1) small farmers are rational; (2) low income countries saddled with traditional agriculture have not the problem of many farmers leaving agriculture for nonfarm jobs; (3) part-time farming can be efficient; (4) economies of scale do not exist in agriculture; and (5) investment in human capital counts much more than institutional changes and is the key to agricultural growth.

    This paper examines and predicts the effects of climate change and climate extremeson China’s land use conversion and soil carbon sequestration under two alternativeclimate change scenarios. It intends to investigate the following three questions. 1)How did climate factors affect land-use conversion in China from 1988 to 2000 andwhat was the relative importance of these factors? 2) How would the predicted futureclimate change pattern affect land-use choice under alternative climate changescenarios?

    This paper examines the impact of farmland readjustment projects on farmland use and structural adjustment in Niigata, Japan. We use census data of rural communities for 1990 and 2000 to conduct pooled regression, first-difference, difference-in-differences, and propensity score matching estimations. We find positive impact of farmland readjustment projects in alleviating farmland abandonment and in facilitating outsourcing of agricultural works and farmland rental.
