Russia’s Military Expenditure During Its War Against Ukraine

This SIPRI Insights paper is devoted to an analysis of military spending by the Russian Federation during its war against Ukraine, and the sources of funding for that spending. Russia’s total military expenditure has increased since its full-scale invasion of Ukraine in February 2022, but not dramatically. Despite difficulty in accessing information on budget spending, total budgeted military spending in 2023 can be estimated at 6648 billion roubles. This represents 4.4 per cent of forecast Russian gross domestic product.

Naval Incident Management in Europe, East Asia and South East Asia

Unprecedented global turbulence in 2022 has demonstrated the need to pay increased attention to naval operations. Enhanced military capability allows naval power projection far beyond home waters. New threats and challenges are emerging from technological advances and new applications, not least the vulnerability of warships and naval facilities to cyber intrusions and cyberattacks. As states implement the programmes they need to protect and promote their interests at sea, there is also likely to be an increase in the number of close tracking incidents.

The World Food Programme’s Contribution to Improving the Prospects for Peace in Sri Lanka

The World Food Programme (WFP) has supported food security and nutrition in Sri Lanka since 1968. Based on research conducted in the Monaragala district in the south, and the Mullaitivu district in the north, on gender dynamics and community resilience, this report aims to identify the ways in which selected WFP projects impact the prospects for peace. The study analyzes the linkages between gender and social cohesion of two WFP resilience-building projects.
