What value for pastoral livelihoods? An economic valuation of development alternatives for ephemeral wetlands in eastern Mauritania

Pastoralism

Research, Policy and Practice

Table 9 The value of botanical and natural resources (as described in Table 8) per wetland based on the number of families regularly using the wetland (based on 1999 market prices)

Wetland	Number of families^a	Average revenue/person UM	Total value of botanical resources UM	Total value of botanical resources, Euro (€)
Chlim	75	43,083	3,231,225	12,405
Sawana	700	43,754	30,627,800	117,582
Tali	200	35,853	7,170,600	27,528
Boichiche	60	61,707	3,702,420	14,214
Goungel	300	14,456	4,336,800	16,649
Tamchekett	588	26,393	15,519,084	59,579
Oum Lellé	Used predominantly by mobile herders, number of regular users unknown

^aThe number of families is based on the maximum number of fields per wetland in all cases except Tamchekett. As there are no fields at Tamchekett, the population of the town is used. Tamchekett has a population of approximately 3,000 (Leffler 1995), which equates to 588 families based on a household size of 5.1 (United Nations 1995)
