Effectiveness of Weather Derivatives as a Cross-Hedging Instrument against Climate Change: The Cases of Reservoir Water Allocation Management in Guanajuato, Mexico and Lambayeque, Peru

Ongoing climate change will increase competition for water. Diversified demand for water—in contrast with the rigid design of water systems, institutions and infrastructure—could hinder the implementation of adaptation policies in water management for Latin American countries. In this context, weather derivatives are proposed as a complementary mechanism for the successful adoption of more efficient water allocations in irrigation districts. Weather derivatives spread risks and incorporate a better understanding of climate system behavior, strengthening irrigation districts’ ability to deal with water availability and demand. The model uses a dynamic water resource allocation model, historical precipitation and Intergovernmental Panel on Climate Change (IPCC) scenarios to find optimal water allocation strategies for the baseline scenario and in the presence of climate change. This analysis is applied to two irrigation districts in Latin America: one in Mexico and the other in Peru, with their corresponding particularities and results.

    This paper uses simple regression techniques to make an initial assessment of the monetary damages caused by the January 12, 2010 earthquake that struck Haiti. Damages are estimated for a disaster with both 200,000 and 250,000 total dead and missing (i.e., the range of mortality that the earthquake is estimated to have caused) using Haiti’s economic and demographic data. The base estimate is US$8. ... (View publication)

    This paper analyzes total factor productivity growth in agriculture in Latin America and the Caribbean between 1961 and 2007 employing the Malmquist Index, a non-parametric methodology that uses data envelopment analysis (DEA) methods. The results show that among developing regions, Latin America and the Caribbean shows the highest agricultural productivity growth. The highest growth within the re ... (View publication)
