Correlation in space between seasonality of malaria and seasonality of rainfall was studied in Sri Lanka. A simple seasonality index was developed by making use of the bimodal seasonality of both malaria and rainfall. The malaria seasonality index was regressed against the rainfall seasonality index taking spatial autocorrelation into account. Despite the presence of spatial autocorrelation, th...

Abstract Climate change is an underlying cause of many extreme events such as enormous cyclones and erratic torrential rains. These phenomena threaten farmers in coastal regions Myanmar. Self-insurance through means crop diversification insufficient for sustainable farm management. Weather index insurance (WII) receiving much attention because its low management costs. An optimum WII contract f...

THIS APPENDIX PROVIDES a simple model of basis risk based on Clarke (2011) and uses it to argue that our 2011 insurance experiment can be used to test whether migration is risky and migrants are risk averse.1 There are two payoff-relevant states {L H} which lead to income at the destination yL ≤ yH . We assume pr(H) = πy . There are two rainfall states {RL RH} and rainfall insurance makes a pay...

Rainfall erosivity is the potential ability for rainfall to cause soil loss. The purpose of this study was to estimate the rainfall erosivity index for the Ghana Atomic Energy Commission site in order to compute the surface erosion rate. Monthly rainfall data, for the period 2003-2012 were used to compute annual rainfall erosivity indices for the site, using the Modified Fournier index. Values ...

Basis risk or residual arising from disparity between an index’s estimate of losses and actual is inherent in index-based insurance products. We approximate basis as the false negative probability (FNP) within pasture, rangeland, forage (PRF) rainfall index for south-central coastal region California. FNP on average that at least one two selected coverage intervals will fail to provide indemnit...

Agricultural production is subject to high risk associated with environmental and agro-ecological conditions. Farmers continuously make decisions to mitigate the various adversities. This study evaluates farm households’ willingness to pay for agricultural risk insurance intervention introduced in Ethiopia in 2009. A bidding game approach is used to elicit willingness-to-pay. We use a unique da...

This study analyzed the spatial distribution of dengue in Rio de Janeiro, Brazil, in 2006, and associations between the incidence per 100,000 inhabitants and socio-environmental variables. The study analyzed reported dengue cases among the city's inhabitants, rainfall, Breteau index (for Aedes aegypti and Aedes albopictus), Gini index, and social development index. We conducted mapping and used...

We consider modelling time series using a generalized additive model with first-order Markov structure and mixed transition density having a discrete component at zero and a continuous component with positive sample space. Such models have application, for example, in modelling daily occurrence and intensity of rainfall, and in modelling the number and size of insurance claims. We show how thes...
