New SIPRI film: Why land-use governance matters for social cohesion and conflict prevention in Senegal

SIPRI is pleased to launch a new film exploring how land-use governance shapes social cohesion and conflict prevention in Senegal. Despite being regarded as one of West Africa’s most stable democracies, Senegal has experienced security challenges and its location in the increasingly volatile Sahel exposes it to broader regional pressures. Addressing the drivers of violence early is therefore crucial for maintaining social cohesion, public trust and peaceful stability. This film was made by SIPRI in cooperation with GIZ, with funding from the German Federal Ministry for Economic Cooperation and Development.

Beyond a legacy of war: Integrating mine action into climate security

Landmine contamination and climate change can interact to create new risks for communities. Flooding and erosion can move mines, while contamination can restrict access to land and hinder climate adaptation and disaster response. This blog explores these overlapping challenges and argues for closer coordination between mine action authorities and institutions responsible for environmental policy, disaster risk reduction and climate adaptation.

Rising Military Spending in the Context of Falling Development Assistance

Funding for sustainable development is facing sharp cuts as global development and humanitarian needs rise, while many donor countries are rapidly increasing military spending. This paper examines the divergence between military expenditure and official development assistance, including case studies of Germany and the United Kingdom. It finds that savings from aid reductions are small compared with planned increases in military spending, but that the cuts will have significant development and humanitarian consequences. An empirical model also shows that current and projected aid commitments fall well below the levels expected in relation to global needs.
