1. GEOGRAPHY AND CLIMATE (Welcomme, 1979)
Burkina Faso (surface area of 274 200 km2) is a landlocked country consisting mainly of flat savanna which lies within the Sahelian zone. In the east, low hills demarcate the White Volta and Niger River watersheds.
The climate is generally hot and arid, with very limited rainfall in the north. The south is somewhat more moist and has one main rainy season extending from May to October.
Burkina Faso is an agricultural country with considerable pastoralism in the north. Much of this area, especially near the water courses, is rendered uninhabitable by Simulium sp, the vector of river blindness. Intensive efforts to control this insect may open up much of the country close to the rivers, with a consequent effect on the development of the fisheries.
2. HYDROGRAPHY
(after Welcomme, 1979; Baijot, 1984a,b; Collart, 1987)
(See Figs. 1 and 2; Tables 1 and 2; Annex 1)
Table 1 gives the surface area and estimated potential annual yield of the main water bodies.
Table 2 gives physical and chemical data of the main water bodies.
2.1 Lakes
There are eight small natural lakes, with a combined surface area of 30–50 km2. The most important are Lakes Bam and Oursi, both of which shrink considerably during the dry season, the latter becoming entirely dry nearly every year.
2.2 Rivers, Floodplains and Swamps
Burkina Faso is well watered with rivers, forming as it does the watershed between the Volta and the Niger systems. The Volta is the most important, with four major tributaries: the Black Volta flows for 650 km within the country and has extensive floodplain/marshes (750 km2 flooded); the White Volta, flows for some 255 km in Burkina Faso, and the Red Volta, for some 350 km. The other river, the Pendjari, forms the frontier with Benin for about 200 km. Within the Niger Basin the Sirba River drains the central hills toward the north.
2.3 Reservoirs
Over 800 dams have been built in Burkina Faso but presently only 320 are in actual use. About 80, with a combined surface area of 130 km2 (max) and 80 km2 (mean), are permanent and exploited by fishermen.
Annex 1 gives an inventory list of 125 main reservoirs and their main characteristics.
In addition, three large reservoirs have recently been created (dams closed in 1987/88): Douna (6 km2), Kompienga (150 km2), and Bagrè (150 km2); and another is projected: Koulbi-Noumbiel Reservoir (350 km2).

2.5 Aquaculture (after Collart, 1987)
Aquaculture is not developed in Burkina Faso, although there are three fish-fry production centres (Bazega, Beregadongan, Komoe).
At present aquaculture consists mainly in extensive stocking of small reservoirs (<50 ha) and of rice culture ponds (total existing area: 10 000 ha).
No data is available on the actual number of man-dug ponds.

4. STATE OF THE FISHERY
(after Welcomme, 1979; Baijot, 1984a,b; Collart, 1987; Deceuninck, 1989a)
4.1 Yield
The statistics available for the estimation of catches from Burkina Faso are not very reliable. As a consequence, the nominal catch figures are more in the nature of general estimations, with little factual data to support them.
Collart (1987) estimates the production to fluctuate from 2 500 to 5 000 t/yr, while FAO's statistics give a fluctuation from 6 000 to 7 000 t/yr during the period 1976–1987.
This production originates from about 3 500 fishermen (including about 500 foreign professional fishermen) distributed in 28 “fisheries centres”.
Aquaculture production is given below: (Source: Vincke, 1989, pers.comm.)
Species | 1982 | 1983 | 1984 | 1985 | 1986 | 1987 |
Oreochromis niloticus | 15 t | 30 t | 74 t | 43 t | 40 t | 36 t |
4.2 Factors influencing yield
The limited area of surface water means that the potential production for Burkina Faso is low and the fishery has remained in a relatively undeveloped state, due mainly to:
Ambitious development plans, based on extensive aquaculture in the barrages and dams, project a production as high as 12 000–15 000 t per year. However, the production of fish from the inland waters of Burkina Faso is severly limited by climatic conditions and, when the Sahelian drought conditions prevail, increases in production cannot be expected.
4.3 Future development possibilities
It is difficult to make any definite forecast for future production due to climatic instability in the area. However, it seems likely that with a concentrated effort, based mainly on stocking existing and projected reservoirs and on fisheries management, the production from various inland water bodies could reach 12 000–15 000 t/yr.
