Evaluating Impacts of Formalization of Water Right for Agriculture Use 2011
Household Survey, Baseline
To address critical issues in water management and increase agriculture production in Peru's Sierras region, the Government of Peru in partnership with the World Bank is currently implementing the irrigation modernization project. The project has the objective of strengthening the technical, financial, and management capacity of farmers and water users' organizations. One of the components of the program - Formalization of Water Rights and Extension to the National Water Registry (PROFODUA) - deals with formalization of water rights for irrigation. PROFODUA's main objective is to improve the livelihood of poor farmers by promoting equitability and reducing uncertainty about water supply for irrigation.
It is expected that PROFODUA's intervention in the Peruvian Sierra will have a high potential for replication in Peru and neighboring countries. To assess the impact of formalization of water rights on a set of development outcomes, a randomized experiment was designed by the World Bank and its Peruvian counterparts. Households in Andahuaylas, Huamachuco, and Tarma regions were randomly assigned to either the treatment or the control group. The research will measure the responses by the groups that were treated, i.e. given water rights and permits, and compare with those that did not receive PROFODUA. Difference-in-difference (DiD) approach will be used to analyze the results of the experiment.
The baseline data collection was conducted from March to July 2011. Data from 1,607 households was analyzed. The follow-up survey is planned for November 2014.

A group of three representative valleys - Andahuaylas, Huamachuco, and Tarma - were selected for the evaluation. These locations were chosen due to their propensity to suffer from droughts, thus making the access to water more important. Researchers focused on valleys with a critical mass of irrigation blocks and that have not received PROFODUA yet. An irrigation block has an average of 400 water users, but this number varies from one block to another. Assuming that there are 80 blocks in a given valley, physical and human capacity constraints limit the implementation of the program to at most 20 blocks per year. Inevitably, it will take four years to serve all the properties in the valley. The identification strategy consists of using a lottery to randomly distribute the blocks into four different groups. Each group will receive the intervention in a different year where the individuals intervened in the fourth year will serve as a control group for those reached in the first year.
To obtain preliminary results on the potential effects of the program, an "external" group was selected to be part of the baseline survey. This external group was comprised by a valley, Huaraz, that was partially intervened. A sample of those blocks that already benefited from the program will be matched to those blocks that were not exposed to the intervention. These intermediate results will serve as a first approximate reference of the "potential" impact of the intervention.
The survey was divided into two stages: initially, the interviews were conducted for the Treatment Group regions in Andahuaylas, Huamachuco, and Tarma, and the program designers sought to interview 1,607 households. As for the Control Group of Huaraz, 401 households were interviewed. The survey includes information for 2,008 households (7,325 individuals).
