Economic considerations for subsistence fish farming (Africa - 18 km) - FAO/CIFA 27

Population density (inhabitants/km2) interpreted in terms of local market demand for fish farming at the subsistence level. Population density as inhabitants/km2 for the year 1988 was obtained from UNEP/GRID Nairobi. **Data publication:** 1994-01-01 **Supplemental Information:** This map derives from a wider study that evaluates inland fish farming potential at a continental-level, published by J.M. Kapetsky with the title "A strategic assessment of warm-water fish farming potential in Africa " . CIFA Technical Paper. No. 27. Rome, FAO. 1994. 67p.

Productivity and variety of crops interpreted as availability of agricultural by products as inputs for fish farming. The objective of this map is to indicate the locations, availability and variety of agricultural by-products that could be used as inputs for fish farming. These can be related to agronomic suitability as measured by the length of growing period (LGP). Agro-ecological zones for 11 crops were defined for Africa by FAO (1978). LGP was calculated from data collected from 730 stations and plotted at 30-day intervals at 1:5 million scale. **Data publication:** 1994-01-01 **Supplemental Information:** This map derives from a wider study that evaluates inland fish farming potential at a continental-level, published by J.M.

Areas in which supplementary food such as agricultural by-products could contribute to the establishment of pond culture systems such as integrated agriculture-aquaculture farming. Data on crops were derived from USGS's Global Land Cover Characteristics database. **Data publication:** 1998-01-01 **Supplemental Information:** This map derives from a wider study that evaluates inland fish farming potential at a continental-level, published by J.Aguilar-Manjarrez and S. S. Nath with the title "A strategic reassessment of fish farming potential in Africa" . CIFA Technical Paper. No. 32. Rome, FAO. 1998. 170p. This study is a follow-up of an earlier assessment of warm-water fish farming potential in Africa by Kapetsky (1994) with the objective to assess locations and areal expanses that have potential for warm-water and temperate-water fish farming in continental Africa.
