This report presents a Cost-Effectiveness analysis of water interventions in Bauchi state,Nigeria, with particular emphasis on pipeline and borehole (Hand pump) water supply schemes.Using the measures adapted from Whittington et al (2008), this study estimates the cost andeffectiveness measures such as time savings and health benefit aimed at reducing the incidenceof and death from, diarrhea disease. First, it conducts a BASIC CEA which compares the cost perhousehold per year of PWS with BWS program. Second, it performs a PROGRAM CEA todetermine the relative effectiveness of the programs. The cost analysis shows that BWS is lessexpensive than PWS. Combining cost and effectiveness, the cost-effectiveness ratio shows theBWS is more cost-effective than the PWS program.

Nevertheless, CEA is not sufficient to determine the most attractive intervention, since itcannot quantify cost and effectiveness in the same unit. Hence, a benefit-cost analysis, whichestimates the monetary value of benefits, is applied. The results of the BCA seem to supportthe evidence that emerged from the cost-effectiveness analysis.

A sensitivity analysis is then performed to determine the robustness of these findings. A onewayand multi-way sensitivity analyses (with worse and best case scenarios) performed on theresults show that BWS is more cost-effective and attractive. The study then concludes with arecommendation that in areas where there are high cases of morbidity/mortality fromdiarrheal, access to portable water and improved health outcomes in densely populated areascan be achieved by diverting resources from BWS to PWS, that is by increasing pipeline watersupply. The converse is true for sparsely populated areas with low cases of morbidity/mortalityfrom diarrheal. However, in mildly populated areas with moderate cases ofmorbidity/mortality, PWS and BWS can be implemented as complements.



Nigeria Economic Update (Issue 15)

Recent data on Nigerias labour market points to a rise in the rate of unemployment and underemployment in 2015Q4. Specifically, compared to 2015Q3, the rate of unemployment and underemployment rose to 10.4 per cent and 18.7 per cent from 9.9 percent and 17.4 percent respectively. These statistics however masks the true situation of the youth employment in Nigeria. Disaggregated data by age category shows that unemployment and underemployment within the youth age category (15-24) was remarkably higher than the national average, at 19 and 34.5 per cent respectively.

Nigeria Economic Update (Issue 11)

In the crude oil market, OPECs weekly basket price increased 1.07 percent from $29.02 per barrel in February 19 to $29.33 per barrel in February 26. A combination of factors were responsible for the slight price increase. First, a decrease in the number of active oil rigs in the US2 (the lowest since 2009) may have marginally eased the glut in the crude oil market. The ongoing efforts by OPEC and other major oil producers such as Russia to freeze oil production have also played a significant role in stemming the downward trend in oil prices. With the current market conditions, the price of crude oil is expected to maintain a fairly stable and modest upward trajectory in the near term.
