Prospects for food security in the 21st Century: with special emphasis on Africa
认为，通过技术、政治和经济手段，到2025年实现全球粮食安全是可能的，但非洲面临更大挑战，需要可持续集约化、政策支持和农业研究投资。
Food security for the world in 2025 is possible and probable if the right set of things are done, starting now. But the task will not be easy. It is both a technology and a political/economic challenge. The challenge for sub-Saharan Africa is even greater. While other regions improved per capita food availability over the last 30 years, Africa's availability declined. But food security is about more than supply. It is also about access which means income generating employment is critical. Meeting future requirements in Africa and the world will require sustainable intensification of complex production systems, appropriate national and international policies and continued investments in agricultural research. Without these conditions and increased employment intensive growth, prospects for the future are less bright. © 1999 Elsevier Science B.V. All rights reserved.
