And after entering WTO,some measures have been taken to enhance maize competitive ability. But there are some difficulties in concentrating production to maize advantaged areas. This paper expounds the basis that Jilin Province becomes the advantage area of maize,analyzes the problems and puts forward the supporting policy. Some strategic measures are proposed,as developing comparable advantages,carrying out the strategy of un-equilibrium development and cultivating advantaged product areas of maize to rapidly improve the international competitive ability and productivity of maize in Jilin Province,cast the agricultural predicament off and promote the agricultural development into a new stage.展开更多

The settlements are located in areas with sandy soils and highly degraded by human action Moreover, the region is considered marginal for the production of coffee, because it is subject to periods of high temperatures, prolonged drought and frost risk, which hinders the sustainability of farms. The environmental and socioeconomic impacts of agroforestry are analyzed through Ambitec-agro system, consisting of a set of indicators aimed at ex-post evaluation of the contribution of technological innovation to environmental, social and economic development of an agricultural activity. The system Ambitec involves: (1) general data collection about the technology; (2) application of questionnaires with adopters selected and insertion of data on impact indicators spreadsheets via platform MS-Excel and to obtain quantitative results and impacts partial indexes and aggregates the impact of technology selected; (3) analysis and interpretation of indices obtained, which vary between -15 and 15. The results indicate that agroforestry management can contribute to: (1) maintaining or increasing the sustainability of traditional coffee-growing regions in the case of sudden climate change; (2) the expansion of the coffee regions now considered unsuitable for the cultivation of coffee; (3) for sustainable regional development.展开更多
