Implications of Recent Randomized Control Trials for the Economic Analysis of Community-Led Total Sanitation (and other related sanitation) Interventions
Oxford Water Network seminar with Prof Dale Whittington, Gillings School of Global Public Health, University of North Carolina – Chapel Hill
7 March 2019, 4pm
Herbertson Room, School of Geography and the Environment, Oxford.
This talk will discuss the economics of Community-Led Total Sanitation (CLTS), a low-cost, non-network sanitation intervention that was developed at the beginning of the 21st Century. There was great hope that CLTS would prove effective, and the Gates Foundation funded a series of Randomized Control Trials (RCTs) that WASH professionals anticipated would support an “evidence-based policy” for the global implementation of CLTS. This presentation will review the findings of these RCTs and re-evaluate the economic benefits and costs of CLTS interventions in light of these findings. The results of these RCTs, coupled with the fact that many other parameters in the benefit-cost calculations are not known with much certainty, suggest that CLTS interventions are risky investments. WASH professionals have not appreciated the risky nature of investments in the package of non-network water and sanitation interventions routinely recommended for poor rural communities in low and middle-income countries. This presentation will also address how some of this risk is a logical consequence of advocating for the achievement of global policy targets such as “sustainable development goals,” which ignore local physical and social realities that inevitably affect the optimal timing and sequencing of sector investments.
