The editors of Climate and Development critique the Reuters "Hot List" of 1,000 influential climate scholars for significant underrepresentation of women and scholars from the Global South, calling for systemic reforms in academic publishing and citation to dismantle colonial models of scientific practice.

The study identifies a critical need for integrated attention to food, water, forest, and energy security in East Africa to achieve sustainable development goals, noting that high reliance on agriculture makes the region vulnerable to climate change. A primary obstacle is the lack of current and comprehensive data, particularly regarding water and energy indices, with some available data dating back to 2016.

The paper examines the gap between climate science and practice, arguing that top-down knowledge production often fails to meet user needs. Based on a five-year collaboration in Sweden involving researchers and local stakeholders, the study finds that while standard knowledge quality criteria (credibility, legitimacy, saliency, usability, and usefulness) are relevant, they are insufficient. The authors conclude that knowledge assessment must also account for case-specific circumstances, the decision-making context, and non-tangible outcomes to determine how knowledge is actually applied by adaptation planners.

The research examines cassava's role in Colombia's bioeconomy, identifying opportunities for value-added products like bioplastics and food. It concludes that realizing this potential requires increasing primary production productivity through sustainable, climate-smart practices and technical assistance for small farmers, without expanding the agricultural frontier.

The document outlines the output of the 'Resilience and management of Arctic wetlands: phase 2 report', which consists of 13 key findings and 20 policy recommendations. These recommendations are organized into six themes, including national governance, climate mitigation, and knowledge building for wetlands management.

The analysis evaluates Estonia's readiness for a hydrogen economy, focusing on the transport and industrial sectors as primary drivers for decarbonization. It models two scenarios (low and high) for hydrogen penetration by 2050, estimating that total investments could reach EUR 22.4 to 44.7 billion. The report highlights that while the transport sector—particularly shipping and rail—and the production of green ammonia and methanol offer the highest potential, significant barriers exist, including a lack of refueling infrastructure, high initial costs, and the need for a national hydrogen strategy. To unlock this potential, the study emphasizes the necessity of increasing renewable electricity capacity, specifically through offshore wind, and providing public investment to kick-start the market.

The survey of 1,269 residents in Helsinki and Tallinn reveals a high valuation of urban nature for pollution reduction, habitat provision, and relaxation, while economic value and community building are seen as less important. Residents in both cities expressed concerns over antisocial behavior and the risk of crime in isolated green areas, as well as the loss of 'wild' nature to infill building. Preferred new green elements include trees, green walls, and meadows. Regarding urban planning, approximately 50% of respondents felt their cities did not actively promote participation opportunities, showing a preference for 3D/VR tools and direct engagement like walks with planners over social interaction with other residents. Area-specific analysis highlights the use of Kalasatama and the Pollinator Highway primarily for exercise, daily errands, and commuting, with walking and cycling as the dominant modes of transport.

The document describes integrated agriculture-aquaculture (IAA) systems as a circular approach to food production that recycles nutrients between crops, livestock, and fish ponds to increase productivity and reduce external inputs. It highlights IAA's potential to adapt to climate change by diversifying livelihoods and managing saltwater intrusion in coastal areas, while potentially mitigating emissions by reducing the need for synthetic fertilisers and animal feed. The text advocates for the ASEAN Technical Working Group on Agriculture and Rural Development to lead knowledge-sharing and policy integration to promote IAA adoption, emphasizing the need for capacity-building and a focus on equity for the most vulnerable farmers.

The document analyzes how socio-economic disadvantages drive air pollution and increase vulnerability to its health impacts in Bosnia and Herzegovina, highlighting the specific risks faced by women, the elderly, and Roma communities.

The report finds that SDG implementation in Sri Lanka is highly synergistic, with only 2% of direct interactions between analyzed targets being restricting. Key 'accelerators' with the highest outward influence include policy coherence, reducing corruption, and climate change capacity. Conversely, targets like drinking water and housing show the lowest outward influence due to potential trade-offs with environmental and resource management. The study emphasizes that because targets are closely intertwined, Sri Lanka requires cross-sectoral collaboration rather than siloed approaches.

The document examines the social, economic, and environmental challenges of urbanization in Sweden and highlights specific municipal projects focused on energy efficiency, low-carbon transport, and nature-based solutions. It emphasizes the role of cities in achieving net-zero emissions by 2045 and the use of green bonds to finance these transitions.

The analysis of 36 SDG targets in Sri Lanka reveals a highly synergistic environment where only 2% of direct interactions are restricting. The most significant 'accelerators' for the entire agenda are strengthening policy coherence, reducing corruption, and enhancing climate change capacity. Conversely, expanding access to drinking water and decent housing present the highest risks of trade-offs, particularly regarding natural resource management and water wastage. The findings emphasize that most trade-offs are non-deterministic and can be mitigated through mindful implementation and institutional coordination.

Estonia generates approximately 167,000 tons of food waste annually, equivalent to 127 kg per capita. Households are the largest contributors, accounting for 48% of total waste and 40% of total food loss. The total monetary value of food wasted in the supply chain is estimated at €164 million per year. The report details waste patterns across sectors, identifying spoilage in households and inadequate sales planning in retail as primary drivers, while recommending strategic roadmaps, improved monitoring, and expanded food donation systems to reduce these losses.

The document examines the intersection of unconventional hydrocarbon extraction and water security in the Vaca Muerta region, highlighting risks from wastewater management and climate-driven water scarcity.

The report examines the challenges of transboundary air pollution in Northeast Asia and compares the region's current cooperation frameworks with the successful models of the UNECE Convention on Long-Range Transboundary Air Pollution (LRTAP) and the USA-Canada Air Quality Agreement. While Northeast Asian countries have implemented strong national measures, regional cooperation remains limited to data sharing and lacks binding emission targets. The authors propose a strategy based on three pillars: building scientific consensus, sharing best practices, and promoting technology cooperation to foster trust and reduce pollutants.

The document examines integrated agriculture-aquaculture (IAA) systems, which recycle nutrients between crops, livestock, and fish to increase productivity and reduce external inputs. It argues that IAA is a promising climate-smart land use approach for Southeast Asia, offering benefits such as livelihood diversification, improved water efficiency, and reduced greenhouse gas emissions. The brief emphasizes the need for inclusive policies, gender equity, and regional cooperation through ASEAN frameworks to scale up these systems for smallholder farmers.

The analysis identifies significant potential for hydrogen adoption in Estonia's transport, industrial, energy, and building sectors. Under an ambitious scenario by 2050, Estonia could avoid 2.2 to 4.4 million tonnes of CO2 emissions and create up to 42,432 jobs, requiring total investments between 22.4 and 44.7 billion euros. The report highlights shipping and rail transport as high-potential areas due to technology maturity and high energy demand, while suggesting that ammonia and methanol production could turn Estonia from an importer to an exporter. Achieving these goals would require substantial increases in renewable electricity capacity, potentially doubling current demand projections, and a comprehensive national hydrogen strategy to coordinate regulatory and financial support.

The report examines gender inequality in the urban public transport sectors of Nairobi, Kampala, and Dar es Salaam, finding that transport systems are generally designed for young, fit men and fail to address the specific mobility needs, safety concerns, and employment barriers faced by women. While national constitutions and gender policies in Uganda, Tanzania, and Kenya provide a foundation for equality, specific transport policies often generalize users and lack explicit gender-responsive measures. The study highlights significant risks of sexual harassment and assault, the underrepresentation of women as drivers and operators due to social stigma and structural barriers, and a lack of gender-disaggregated data to inform policy. It suggests that the introduction of Bus Rapid Transit (BRT) systems and the rise of online taxi-hailing services present opportunities to integrate gender-sensitive infrastructure and flexible employment for women.

The report examines the ecological importance of Arctic wetlands, particularly their role in global carbon storage and biodiversity, while analyzing the public policy frameworks used by Arctic states to manage them. It highlights that while scientific knowledge of wetland functions is extensive, significant gaps exist in policy coherence, the influence of societal interest networks, and real-time mapping. The document advocates for a Social-Ecological Systems (SES) approach to stewardship, emphasizing the necessity of indigenous and local community participation and the adoption of advanced geospatial AI tools to improve wetland inventories and monitoring.

The document examines the cassava value network in Colombia, highlighting its current use in food and industrial sectors and its potential for bioplastics and animal feed.
