Book excerpt: In the decade since the signing of the Ottawa Treaty, which banned the production and use of anti-personnel mines, governments have spent over $3 billion on clearing up and mitigating the security threat of mines, cluster munitions and other unexploded ordnance in the world's current and former war zones. However, this flow of cash into regions dominated by violent social structures raises numerous political issues. Through detailed archival and field research, this book explores the politics behind the allocation and implementation of foreign aid by the US and Norway for demining in Afghanistan, Bosnia and Sudan. It is an essential resource for practitioners and policymakers working in the field of landmine clearance and for students and researchers of Development Studies and post-war reconstruction.
