Flows of Funds for Disaster Recovery and Reduction

Disaster aids between countries and agencies also form a spatial interaction network which could help us understand the distribution of funds for disaster reduction and recovery across the world. Disaster Aid Mapper depicts disaster aid flows by disaster categories, funding organization and over the years. You may display a flow map of funds by disaster type(e.g., drought, earthquake, flood) , funding source (e.g., government, ngos, United Nations), and by year (2000 - 2010).
