Effect of prescribed burning on temperate and boreal forest biodiversity: a systematic review
A systematic review of 244 studies on prescribed burning in temperate and boreal forests found significant positive effects on vascular plant richness and herbaceous plant richness in broadleaf forests, though outcomes remain difficult to predict and may harm conservation-dependent taxa.

Effective Public Investments to Improve Food Security
The document reviews 87 cases of agricultural interventions, finding that nearly 70% had a positive impact on food security. It emphasizes that success depends more on local context and implementation—such as addressing wealth inequality and combining interventions—than on the specific type of investment. Key analyzed areas include input subsidies, value chain development, and extension services, with recommendations for using direct food security indicators and rigorous baseline assessments in future planning.

COSTS OF POLLUTION IN CANADA
The report finds that pollution imposes very significant costs on Canadian families, businesses, and governments, with direct welfare costs alone estimated at $39 billion in 2015. It highlights substantial data gaps regarding persistent organic pollutants, heavy metals, and climate change, while detailing specific impacts such as urban smog, algal blooms in Lake Erie, and the long-term liabilities of contaminated sites and nuclear legacy wastes.

Bioenergy production and sustainable development
A systematic review of scientific literature on bioenergy production and sustainable development reveals a limited evidence base for policy-making, with research concentrated in a few countries and focused primarily on agricultural biomass plantations. While economic and technological impacts are often reported as positive, social and environmental impacts tend to be negative, except for the direct substitution of greenhouse gas emissions from fossil fuels.

Solution scanning as a key policy tool: identifying management interventions to help maintain and enhance regulating ecosystem services
The authors propose 'solution scanning' to provide policy-makers with a comprehensive, verified list of environmental interventions. Through a systematic consultation, they identified 296 possible interventions across various regulating services, noting that those reducing soil loss and maintaining forest cover often provide multiple benefits.

Community resilience to natural hazards and climate change impacts: a review of definitions and operational frameworks
The paper argues that effective disaster resilience frameworks must integrate sustainable development, disaster risk reduction, and community engagement, while treating resilience building as a process rather than just a set of outcomes to allow for monitoring and evaluation.

The Polls-Trends: Twenty Years of Public Opinion about Global Warming
This research paper synthesizes data from hundreds of polling questions across more than 70 surveys to identify long-term trends in public opinion on global warming. The review focuses on six dimensions: public awareness, understanding of causes and policy, perceptions of scientific certainty and expert agreement, concern over impacts, support for policy action relative to economic costs, and support for the Kyoto climate treaty.

Addressing Loss and Damage
The report examines how National Adaptation Plans (NAPs) are used by developing countries to identify, communicate, and minimize loss and damage, noting that nearly half of these plans explicitly reference the concept.

Does Education Lead to Pacification?
The review finds a general scholarly consensus that higher levels of education have a pacifying effect on civil conflict, though this relationship is complex and varies by the type of violence. While low education is often linked to recruitment in civil wars, higher education levels are frequently observed among terrorists and genocide perpetrators. The authors highlight that inter-group educational inequalities—particularly along ethnic and religious lines—significantly increase conflict risks, whereas rapid expansions in tertiary education do not appear to drive destabilization. The document concludes that while education generally promotes peace, its impact is mediated by factors such as regime type, gender equality, and the specific nature of the political violence.
