Book (series)Technical studyEnhancing or restoring the productivity of natural populations of shellfish and other marine invertebrate resources 2003
Also available in:
No results found.A broad review is provided of factors relevant to enhancing populations of invertebrate resources and methods promoting their recovery by natural recruitment, restocking or habitat restoration. The review focuses on the biological, technical, environmental, economic and biological factors affecting the feasibility of restoring or enhancing productivity of commercially valuable local invertebrate populations. Three categories of enhancement activity are recognized: restoring or enhancing stocks b y conventional management methods, transplanting or seeding, and the use of juveniles produced from collectors in the wild or from hatcheries. Some guidelines are provided on issues related to enhancing recruitment, site selection, experimental closures, ecosystem considerations including predator control, as part of a stock management and enhancement programme. Ownership and co-management issues, and the necessary decisional rules for successful management are discussed, as well as how to recon cile the enhancement programme with other uses of the coastline. Spatial and geographical considerations are addressed, including allocation of areas for enhancement, rotational harvest schemes, use of refugia for protecting juveniles and the spawning stock, and the impact of the use of coastal zones for other human activities. -
No Thumbnail AvailableBook (stand-alone)Technical bookDemand forecasting for fertilizer marketing 1994
Also available in:
No results found.Almost every decision a manager takes needs a forecast. If he has an idea of what will happen in the future, he can make appropriate management decisions. He also needs to assess the effect of his present decisions on the future so that the right decisions are made today to create a desired condition tomorrow. Fertilizer is capital intensive and, therefore, cost sensitive. If we know what fertilizer types are likely to be demanded, where and when, we can improve the quality of decisions concerni ng production, procurement, placement and promotion. Consequently, we can minimise funds tied up in inventories, save interest costs, conserve foreign exchange, avoid running out of stock and, generally, increase sales and improve profits. -
No Thumbnail AvailableBook (series)Technical studyChronicles of Marine Fishery Landings (1950-1994): Trend Analysis and Fisheries Potential 1996
Also available in:
No results found.World fishery landing statistics as disseminated by FAO have been completely revised for the period 1950-1969 and time series in the database have been extended backwards by 20 years so that the period covered is now 1950-1994. Through a preliminary analysis of trends, globally and by oceans, we attempt to demonstrate that these extended time series can be very useful in interpreting developments in the world’s fisheries and so help in assessing the present situation as well as for planning and policy-making for the future. Grouping the 200 most important resources into a few categories according to the shapes of their landings trends reveals a variety of patterns which seem to form different segments of a generalised fishery development model comprising undeveloped, developing, mature and senescent phases. The analysis demonstrates strikingly the succession of the passage of the majority of the world’s major resources through these phases, indicating the current general saturation of fisheries development and increasing overexploitation. Fisheries potential was estimated by predicting at which point the relative rate of increase of landings is zero, using the same generalised fishery development model applied to total fishery production data for marine fish and shellfish. The analysis was applied using data aggregated to three different levels, namely (1) a total for all oceans, (2) totals for each ocean, and (3) individual FAO major fishing areas. Estimated fishery potent ial for the world’s oceans increases as the level of aggregation of the data decreases, and the results indicate that marine fishery potential may be higher than has been assumed up to now. The areas and resources which might provide potential increases in production are identified.

IndexesLibrary Classified Catalogue (2)/ Bibliothèque de catalogues systématiques (2) 1948
Also available in:
No results found.The Protocol of 8-9 July 1946 relative to the dissolution of the International Institute of Agriculture, transferred the functions and assets of the said Institute to FAO. Of these assets, the Library is unquestionably the most outstanding and is a lasting record of the Institute's work and its achievement in the field of agriculture. This catalogue will undoubtedly contribute towards a better knowledge of this international Library. This volume in its present form, represents the systematic card-index, by subject of the Brussels Decimal Classification, in French and English, and it's supplemented by the general alphabetical index of authors.
This is Part 2 of 4 - Books - section Pure Sciences, Applied Sciences, Hygiene, Fine Arts, Literature, History, Geography and Biography.

No Thumbnail AvailableBook (stand-alone)Training materialPlanning in government forest agencies how to balance forest use and conservation: agenda for training workshop. 1998
Also available in:
No results found.The purpose of planning for forestry development is to establish a workable framework for forest use and conservation which incorporates the economic, social and environmental dimensions on a sustainable basis. The framework is about creating a shared vision of how forests will be used and protected. This can be summed up in a single central question: Trees and forests for whom and for what? The question is not new but what is new is the perception that so many different groups have an interest in the reply. Forestry planning has traditionally been mainly concerned with the production of timber for industry and other wood products, and with forest industry development. Planning for environmental goals also has a long history but was largely restricted to designated areas for exclusive conservation. National forestry development agencies were essentially responsible for the sustained yield management on protected public forest lands and for reserved forests. The term "sustained yield " was mostly limited to wood production and therefore excluded the majority of other forest products and services. Although most forestry agencies have made progress towards multiple-use management, planning remains often biased towards timber in a wide range of countries. Many of the actions taken in order to stimulate forestry development in the immediate failed to sustain the momentum of growth in the longer term. Short term achievements sometimes resulted in degradation or destruction of the stock of natural capital needed in order to maintain growth in the future or reduced options for future end uses by degrading the forest capital. -
