Abstract

The introduction of science and technology into agriculture over the past two centuries has markedly increased agricultural productivity and decreased its labor-intensiveness. Chemical fertilization, mechanization, plant breeding and molecular genetic modification (GM) have contributed to unparalleled productivity increases. Future increases are far from assured because of underinvestment in agricultural research, growing population pressure, decreasing fresh water availability, increasing temperatures and societal rejection of GM crops in many countries.

摘要

过去两个世纪，科学技术在农业领域的应用显著提高了农业生产力，降低了劳动强度。化肥、机械化、植物育种和分子遗传修饰（GM）技术的应用促成了前所未有的生产力增长。但由于农业研究投入不足、人口增长压力增大、淡水资源减少、气温升高以及许多国家社会对 GM 作物的抵制，未来的增长前景并不乐观。
