“…Similar impacts of farmland loss have been also found in other developing countries. For instance, negative effects of farmland loss were reported in China (Chen, 2007;Deng, Huang, Rozelle & Uchida, 2006) and India (Fazal, 2000(Fazal, , 2001. Nevertheless, positive effects were found in China (Chen, 1998;Parish, Zhe & Li, 1995) and Bangladesh (Toufique & Turton, 2002).…”

Livelihood Strategies for Coping with Land Loss among Households in Vietnam's Sub-Urban Areas

Using a novel data set from my household survey in a sub-urban district of Hanoi, Vietnam, this study is the first attempt using an econometric approach to investigate the relationship between farmland loss (due to urbanization and industrialization) and households' livelihood strategies. The results from the multinomial logit model provide the first econometric evidence that land loss increases with the probability of households adopting a strategy specializing in a single nonfarm activity (informal paid jobs or household businesses) or diversifying in many activities. This suggests that many households have actively coped with the shock of losing land. Such adaptation strategies in the new context can help mitigate their dependence on farmland as well as might help improve their welfare. Therefore, a possible implication here is that the rising of land loss should not be seen as an absolutely negative phenomenon because it can improve household welfare by motivating households to change or diversify their livelihoods. Besides, some household asset-related variables such as education, farmland, and the prime location of houses were found to be closely associated with participation in nonfarm activities. Based on evidence from the econometric analyses, the study proposes some policy recommendations that may help households diversify or specialize in lucrative nonfarm activities, given the context of shrinking farmland due to rapid urbanization in Hanoi's sub-urban areas.

“…With the rapid increase of population and development of urbanization, the growing demand for resources, especially for cultivated land resources, has led to the conversions among different land uses. The structural change and pattern succession of the land system will undoubtedly lead to changes in suitability and quality of land, and directly influence land productivity (Gao and Deng, 2002;Deng et al, 2006). To ensure food security, China has formulated a national policy that a minimum of 1.8 × 10 9 mu (1.2 × 10 9 ha) of cultivated land must be available.…”

Food safety and its related influencing factors in China are the hot research topics currently, and cultivated land conversion is one of the significant factors influencing food safety in China. Taking the North China Plain as the study area, this paper examines the changes of cultivated land area using satellite images, estimates land productivity from 1985 to 2005 using the model of Estimation System for Land Productivity (ESLP), and analyzes the impact of cultivated land conversion on the land production. Compared with the grain yield data from statistical yearbooks, the results indicate that ESLP model is an effective tool for estimating land productivity. Land productivity in the North China Plain showed a slight decreasing trend from 1985 to 2005, spatially, increased from the north to the south gradually, and the net changes varied in different areas. Cultivated land area recorded a marginal decrease of 8.0 × 10 5 ha, mainly converted to other land uses. Cultivated land conversion had more significant negative impacts on land production than land productivity did. Land production decreased by about 6.48 × 10 6 t caused by cultivated land conversion between 1985 and 2005, accounting for 91.9% of the total land production reduction. Although the land productivity increased in Anhui and Jiangsu provinces, it can not offset the overall adverse effects caused by cultivated land conversion. Therefore, there are significant meanings to control the cultivated land conversion and improve the land productivity for ensuring the land production in the North China Plain.

“…The average interpretative accuracy of the land use maps is over 95% (Liu et al, , 2005(Liu et al, , 2010a. The land use was divided into six primary types (cultivated land, forestry area, grasslands, water areas, built-up area, and unused land) and 25 sub-classes (Deng et al, 2006(Deng et al, , 2010.…”

a b s t r a c tThe Heihe River Basin (HRB) is the second largest inland river basin in the arid region of northwestern China. An agricultural oasis is a typical landscape in arid regions providing precious fertile soil, living space and ecological services. The agricultural oasis change has been one of the key issues in sustainable development in recent decades. In this paper, we examined the changes in the agricultural oasis in HRB and analyzed the socio-economic and climatic driving forces behind them. It was found that the agricultural oasis in HRB expanded by 25.11% and 14.82% during the periods of 1986-2000 and 2000-2011, respectively. Most of the newly added agricultural oases in HRB were converted from grassland (40.94%) and unused land (40.22%). The expansion in the agricultural oasis mainly occurred in the middle reaches of HRB, particularly in the counties of Shandan, Minle, Jinta and Jiuquan city. Changes in the rural labor force, annual temperature and precipitation have significant positive effects on agricultural oasis changes, while the ratio of irrigated agricultural oases has significant negative effects on agricultural oasis changes. The agricultural oasis expansion in HRB is the combined effect of human activity and climate change.
