Opis: If irrigated production is to make a significant contribution to food security and economic growth in Sub Saharan Africa, it will have to be re-structured across the region as a whole. This is the main conclusion of a study undertaken by FAO to analyse the drivers of demand for irrigated production in Sub-Saharan Africa (SSA). Steeply rising commercial food import bills for staple crops across SSA are indicative of the level demand that is not being met from domestic production. The increase of area under equipped/spate irrigation for the whole of Africa over the last ten years amounts to 1.27 million ha, which is equal to about 127 000 ha a year. This rate of growth has proved too low to have an impact on food import bills and buffer regional food security. However, within subregional trading groups there is scope for consolidation of market supply. Irrigated production opportunities in SSA could be realised where natural resources and markets coincide, but only through a great deal more attention to costs of production, price formation, effective water allocation mechanisms, economically efficient water use and strong, responsive institutions.--Publisher's description.

Lumpfish caviar - from vessel to consumerJon Johannesson
Opis: Fish roe products have historically been seen as expensive and highly-desirable luxury food items. The best and most expensive is true caviar, which uses eggs from sturgeons caught in the Caspian Sea. In recent years, eggs from many other fish species have been used to develop products imitating original caviar. By utilizing processes appropriate for each kind of fish, it is now possible to make a similar - but nevertheless imitation - product. This publication presents a comprehensive overview of the production of lumpfish caviar as a model for developing fish caviar. The source, lumpfish (Cyclopterus lumpus), is from the North Atlantic and can be used as a case study to develop similar products from other fish species. The document describes fishing methods, preservation and storage of the eggs as well as details on the caviar production process itself to obtain the final product, lumpfish caviar. Product safety and packaging are considered, and the rules and regulations that apply to the main markets are discussed. Production and marketing statistics demonstrate the extent of the global lumpfish caviar business. The publication draws heavily on source material from Iceland, a major producer and processor, and includes many illustrations.
