Vegetable Cultivation

Organic cultivation has been promoted in recent years as a possible alternative to conventional cultivation in order to reduce environmental burdens and nonrenewable resource use. However, a comprehensive assessment of the sustainability of different vegetable cultivation modes is currently lacking. In this study, a combined use of economic analysis (ECA), emergy analysis (EMA), and lifecycle assessment (LCA) was conducted to evaluate the economic performance, resource use, and environmental impacts of three greenhouse eggplant production modes, namely conventional (CON), low-input (LOW), and organic (ORG) cultivation. ECA results showed that the economic profit and value to cost ratio of ORG increased by 14%–17% and 36%–41% compared with CON and LOW, respectively. EMA results showed that ORG had higher resource use efficiency. The unit emergy value and emergy sustainability index of ORG increased by 37%–49% and 45%–65% than those of CON and LOW, respectively. LCA results revealed lower potential environmental impacts for ORG, and its total potential environment impact index was 80%–91% lower than that of CON and LOW. These results showed that organic vegetable cultivation reduced resource and environmental costs while increasing farmers’ income, which is the most sustainable vegetable production mode in the North China Plain.

The North China Plain (NCP) is the most important winter wheat production region and an area of water shortage in China. The stability of winter wheat (T. aestivum L.) production in spatial pattern and the sustainability of water resources have been a major policy concern in China. This study explored the barycenter shift and change trends of wheat total production during 1998–2015, using methods of barycenter model, Sen’s slope, and Mann Kendall test, and analyzed the influence of external factors and the response of water resources. Results indicated that the barycenter of wheat production moved southwards by 115.16 km during 1998–2015, with an average speed of 6.77 km/year. For the entire NCP, the total production showed phased changes during the study period: It decreased during 1998–2003, and then continuously increased during 2004–2015. Of the wheat production increase in the NCP, yield increase and sown area expansion averagely contributed 64.5% and 35.5%, respectively, and the contribution proportion of yield increase continuously increased since 2003. At county level, total wheat production showed a significant increase and decrease trend in 87 and 29 counties, mainly distributed in the southern and northern NCP, respectively. The increase of total production at county level was mainly contributed by yield growth in the southern NCP, while the decrease in the north was due to the reduction of sown area to great extent. The southward shift was jointly resulted by the spatial variation of input factors, benefit, and water prices. These spatial pattern changes alleviated the water pressure in the north region to some extent, in the case of ensuring the production increase of winter wheat. Therefore, the current spatial shift should be continuously promoted in the future.
