Among its natural endowments (such as oil, minerals, fish, solar energy, abun dant rains) the vegetation is the most essential resource for mankind, almost endlessly diversified and close at hand: timber of many kinds, some among the most valuable in the world, resins, medicine, foodstuffs for man and feedstuffs for animals. They exist in plenty and vary widely and will remain so if the plant cover is carefully managed and exploited. The population of South-East Asia may profit in many ways from its natural heritage, now and in the future. A strict condition for the survival of the many millions inhabitants is the maintenance of a thriving plant cover. Extensive in formation on the plants growing in the region is needed to allow access to the plant resources of each country. Thorough knowledge of plant resources is es sential for human life and plays a key role in ecologically balanced land use. The information needed includes botany, ecology, agronomy or silviculture, plant breeding, technology and economics. Vast amounts of printed and manuscript data on South-East Asian plants ex ist, making the available knowledge overwhelmingly large. However these data are scattered over countless books, articles and reports, written in many different languages over a period of almost two centuries, and often not accessi ble. In daily practice, thousands of workers in agriculture, forestry, research, education, extension, trade and industry have access to only a small part of this reservoir of knowledge. Handbooks on plant resources dealing with different parts of South-East Asia, leading publications in the past, were written half a century ago and are now obsolescent. Since then, research in tropical agronomy, forestry and economic botany has continued, rapidly expanding, aided by new techniques, checking and correcting, discovering new properties, food values, medicinal efficacies or dangers, ecological relations between cultivated and wild plants (environ ment), studying the prevention of erosion, weed invasion and many other relat ed subjects. The time has come for review of all the facts, old and new, to eliminate errone ous notions, to point out the most profitable way of handling plants and to avoid losses through ignorance, in short to make available a comprehensive easily consulted reference work. The Agricultural University at Wageningen has taken the necessary initiative with the Prosea Project, short for 'Plant Resources of South-East Asia'. Other institutions in the Netherlands have expressed their interest and are prepared to cooperate, in particular the National Herbarium at the University of Ley- den, the Centre for Agricultural Publishing and Documentation (Pudoc) at Wageningen and the Royal Tropical Institute at Amsterdam. 10 PROSEA PROPOSAL The Minister of Education and Science has granted a subsidy to start the Prosea Project. A Board of Trustees for the coordination and supervision of the project within the Netherlands was appointed, under the presidency of Dr W.M. Otto, former ly Director-General of the Ministry of Agriculture and Fisheries. The survey and compilation of existing knowledge of about five thousand plants in South-East Asia is an extensive, complicated and unique enterprise, which can succeed only with international support and scientific, organization al and financial cooperation. Consultation and discussion is needed on the scope and implementation ofth e Prosea Project with institutions in South-East Asia, international agencies and private firms. To facilitate these discussions, the Proposal for a handbook presented here includes a description ofth e project and examples of how information on certain plants could be compiled. The sample includes some familiar and some less familiar plants. Contributions were written by specialists from various institutions in the Netherlands. Suggestions and criticisms are invited on scientific, educational and other aspects of the Prosea Project; the scope, planning, priorities, and the textual and pictorial layout of the forthcoming handbook may require adjustment. An active supportive interest from agencies, research and institutions, and in dividual scientists would be most welcome, and should benefit the forthcoming work and its users. There is every reason to expect that a long desired and adequate general source of essential and up-to-date information will come within the reach of agronomists, horticulturists, silviculturists, ecologists, economic botanists, plant breeders, experts on medicinal plants, teachers, students, advisory work ers and scientists in industry. The planned handbook is intended to be a survey, guide and directory to an in exhaustible resource for human welfare: the evergreen treasury of South-East Asia. Wageningen, July 1986 C.C. Oosterlee Rector Magnificus, Agricultural University, Wageningen, the Netherlands 1 The Project on 'Plant Resources of South-East Asia' (Prosea) South-East Asia for the purposes of Prosea includes Malaysia, Singapore, Brunei, Indonesia, the Philippines, Papua New Guinea, and parts of Vietnam, Laos, Cambodia, Thailand and Burma. Strict definitions of the region include only the area from Malaysia to Papua New Guinea. However from a floristic, agricultural and forestry point of view, all these countries and even Sri Lanka and part of India (Kerala) show some similarity. The last pages ofthi s book con tain a map of the area of South-East Asia that Prosea covers. A great majority of the population in this region, a total of 300-400 million people, largely depends on the plant cover, the useful plants in particular, for its survival and well-being. A modern handbook giving information about pos sible uses of plants, both cultivated and growing wild, the plant resources, is lacking for South-East Asia. As for the uncultivated flora, Malaysia, Singapore, Brunei, Indonesia, the Philippines and Papua New Guinea are in the favourable position that a cur rent taxonomie work provides excellent basic information.
