Genetic study in a few basic plants, including using chemical compounds as insecticides and fertilizers, opened the way in which within the Fifties and Sixties to nice alterations in method in agriculture - with spectacular ends up in the tropics. this variation turned referred to as the fairway Revolution - a very nice revolution in equipment and fabrics which, while utilized with intelligence, made attainable in many years the fulfillment of whole sufficiency in cereals creation in South and South East Asia, Mexico and South the United States. After twenty years of continuing luck, points of the fairway Revolution have to be rediscussed within the gentle of latest findings and chances provided by way of medical and technological growth - and destructive negative effects on atmosphere and wellbeing and fitness.
These papers study the current country of agriculture, and point out the future of its improvement, in particular within the tropics and, particularly, Africa and South the US. the necessity for extra study is under pressure; priorities within the program of this examine are mentioned, resembling the industrial facets of any new approach to be followed, and the necessity to appreciate the ecological equilibria of alternative environments and the stability of strength input/output in a given agrosystem.

The closing remarks examine the current role of the international community, particularly the United Nations system, in designing programmes addressing some of the environmental challenges posed by chemical pesticide pollution. 1. CHEMICAL SUBSTANCES A literature review enables a rough estimate of the various kinds of chemicals currently circulated into nature as a result of technological advances to be placed at approximately five million, about 70,000 of which are marketed, either in com- (*) United Nations Environment Programme, Nairobi.
It places increasing pressure on decreasing resources and calls for larger supplies of produce to meet the ever-increasing demand for energy, fibre and food. To arrest this situation, developing countries have increasingly continued to rely on programmes for: (i) the introduction of high-yield plant varieties (ii) the expansion of arable land through reclamation of swampy and other areas — 55 — (iii) increasing land productivity through irrigation, and (iv) intensive use of agrochemicals - chemical pesticides and fertilizers.
