Abstract 

Landmines and Explosive Remnants of War (ERW) continue to represent a significant nuisance for society inaffected countries. Coping with humanitarian and development activities, mine action aims at both, reducing theimpacts of the presence of landmines/ERW on the population, and ultimately returning cleared land to the communities.These are the main tasks of mine action decision makers. This study combines landmine/ERW contamination datawith explanatory variables that contain information about underlying targets. They are integrated into a risk mappingframework using Geographic Information Systems with other information sources, such as remote sensing. The aim ofthis paper is to provide insights into the populations and/or locations at risk caused by landmine and ERW impacts on abroad and local scale. Thus, the concept of { extquoteleft}hotspots{ extquoteright} is particularly useful because it provides a visual representationof exposure, aided by a geo-spatial representation of { extquoteleft}priority areas for mine action planners to focus on. We apply theKernel Density Estimator (KDE) to derive such { extquoteleft}hotspots{ extquoteright}. KDE is proposed as the basis to define landmine and ERWhazard, vulnerability, and element-at-risk maps, which enable producing a final output, the landmine/ERW risk map. Thisis accomplished by using an adaptive kernel bandwidth for datasets with highly heterogeneous spatial distributions, anda problem-specific method for generating point samples from polygon data, before using them as inputs for KDE. Thegeo-statistical model presented here is a time-and-cost-efficient method to construct a landmine risk map, that is asrepresentative as those produced by mine action actors. It can be used as a complement to the risk area maps madeby these actors because they are slightly different but show a large degree of overlap. Moreover, the method helpsrevealing the variables which are the most linked to landmine/ERW-related events in the study area
