英文摘要 | Globally, there are adequate high qualitylands to support nearly double the currentpopulation. However, Asia already has an acuteland shortage and as a region it is already foodinsecure. Feeding the 4.2 billion people in theyear 2025 cannot be achieved with theavailable land resources. Under the low-inputsystems in much of Asia, productivity willcontinue to decline with land degradation andother land-consuming factors taking their toll.Further, lack of political will, insufficientinvestments in modern agriculture, and ageneral apathy to tenets of sustainable landmanagement guarantee food insecurity and insome countries, contribute to poverty andfamine. From and Asian land-productivitypoint of view the specter of the Malthusianscenario is most relevant. Local and regionalfood shortages are likely to continue to occurunless mechanisms for equitable fooddistribution, effective technical assistance andinfusions of capital for infrastructuredevelopment are implemented in mostcountries of Asia. |
