Global demand for timber, agricultural commodities, and extractives is a significant driver of deforestation worldwide. Transparent land-concessions data for these large-scale commercial activities are essential to understand drivers of forest loss, monitor environmental impacts of ongoing activities, and ensure efficient and sustainable allocation of land.

Landscape Epidemiology Modeling Using an Agent-Based Model and a Geographic Information System

Peer-reviewed publication
Junio, 2015

A landscape epidemiology modeling framework is presented which integrates the simulation outputs from an established spatial agent-based model (ABM) of malaria with a geographic information system (GIS). For a study area in Kenya, five landscape scenarios are constructed with varying coverage levels of two mosquito-control interventions. For each scenario, maps are presented to show the average distributions of three output indices obtained from the results of 750 simulation runs. Hot spot analysis is performed to detect statistically significant hot spots and cold spots.
