Soil suitability for ponds construction (Africa - 5 km) - FAO/CIFA 32

Soil texture interpreted in terms of suitability for pond construction. Soil texture data was obtained from the FAO-UNESCO Soil Map of Africa at 1:5 million scale. This dataset includes three soil texture classes: coarse, medium and fine and these are given for the dominant soils of each association and refer only to the upper 30cm. **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.

Suitable areas for the construction of fish ponds based on a slope evaluation. Slope was derived from a global digital elevation model (GTOPOP30) in the form of percentages. **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.

Slope interpreted in terms of suitability of topography for pond construction. Slope data was obtained from the FAO-UNESCO Soil Map of Africa at 1:5 million scale. This dataset includes three slopes classes which reflect the topography in which the soil association occurs. **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.

Engineering capability for pond construction obtained by combining soil texture and slope. Soil texture was interpreted in terms of suitability for pond construction. Soil texture data was obtained from the FAO-UNESCO Soil Map of Africa at 1:5 million scale. This dataset includes three soil texture classes: coarse, medium and fine and these are given for the dominant soils of each association and refer only to the upper 30cm. Slope was interpreted in terms of suitability of topography for pond construction. Slope data was also obtained from the FAO-UNESCO Soil Map of Africa at 1:5 million scale. This dataset includes three slopes classes which reflect the topography in which the soil association occurs. **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.

Map derived from the combined suitability of areas apt for small-scale fish farming development and operation with areas with potential yield (crops/y) of African catfish for small-scale farming. Areas with suitability for small-scale fish farming were derived from the combined suitability of four land-quality factors important for fish farming development and operation; net annual water requirement for shallow ponds, soil and terrain suitability for the construction of fish ponds, potential livestock wastes and agriculture by-products as feed and fertilizer inputs, and potential for farm-gate sales. Predictions of growth were based on water temperature, in turn predicted from air temperature and wind velocity data. Gridded values of mean monthly daily minimum and maximum temperatures were obtained from the Centre for Resource and Environmental Studies (CRES) at the Australian National University. Mean annual wind velocity was obtained from UNEP/DEIA/GRID-Geneva. **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.

Map derived from the combined suitability of areas apt for commercial fish farming development and operation with areas with potential yield (crops/y) of African catfish for commercial farming. Areas with suitability for commercial fish farming were derived from the combined suitability of five land-quality factors important for fish farming development and operation; net annual water requirement for shallow ponds, soil and terrain suitability for the construction of fish ponds, potential livestock wastes and agriculture by-products as feed and fertilizer inputs, potential for farm-gate sales and potential market demand. Predictions of growth were based on water temperature, in turn predicted from air temperature and wind velocity data.
