The SEI Urban Toolbox for Liveable Cities is a living digital resource hosted on the weADAPT platform, designed to gather SEI-developed tools for city officials, residents, and community groups. Developed through a four-phase co-design process involving internal reviews and workshops with stakeholders in Thailand, Kenya, Uganda, Rwanda, Zambia, and Colombia, the toolbox focuses on improving environmental conditions, health, and well-being. Key findings from stakeholder workshops emphasized a strong demand for tools that foster citizen science, participatory mapping, and open data access to inform decision-making. The toolbox organizes resources into four main domains: residents' wellbeing, neighbourhood conditions, environmental quality and ecosystem services, and cross-cutting issues.

The lower Songkhram River basin, the last free-flowing tributary of the Mekong, supports over 14,000 households through capture fisheries and floodplain agriculture. Despite being protected under the Ramsar Convention, the Mekong River Commission, and Thailand's Master Plan for Integrated Biodiversity Management, these wetlands face threats from hydropower dams in the upper Mekong, agricultural expansion, and industrial pollution. Current management is hindered by a lack of coordinated procedures, the marginalization of traditional knowledge, and the prioritization of development over ecological conservation. The document recommends strengthening collaborative governance, valuing wetland ecosystem services, and increasing financial flows for conservation to ensure regional food and water security.

The paper examines seven urban sustainability interventions in small and intermediary cities of the global South, focusing on disaster risk reduction, adaptation, emission reduction, and resource management. Using a framework to analyze actors and drivers, the study finds that the entities leading and financing projects significantly influence the inclusivity of the process and the resulting environmental framing. The analysis includes primary case studies from Nakuru, Kenya, and Udon Thani, Thailand.

The 'Kin Dee You Dee' toolkit uses three sets of serious games to build climate resilience in urban low-income communities. The process moves from creating awareness of resilience concepts to mapping assets and risks, and finally developing strategic response plans. Applied in the Bangkok Metropolitan Region and Udon Thani province, the toolkit is concluded to be a useful instrument for policymakers and stakeholders to increase community engagement and disaster risk awareness.

The report examines how secondary cities in the Global South navigate sustainability transitions using a multi-level governance framework. Through eight case studies, it analyzes the roles of national, provincial, and local governments, private sector actors, and community-based organizations. The findings highlight that while disasters often trigger local action, a lack of financial autonomy and institutional coordination frequently hinders the scaling of pilot projects. The report argues for a shift from purely participative to collaborative governance to improve inclusivity and sustainability outcomes.

The SEI Initiative on City Health and Wellbeing focuses on the intersection of urban growth, environmental quality, and resident wellbeing, particularly in low- and middle-income countries. Using case studies in Nakuru, Kenya, and Udon Thani, Thailand, the initiative employs a multi-disciplinary approach to study the impact of urban forms, co-design citizen science monitoring, analyze urban metabolism through participatory modelling, and examine governance for urban equity. The goal is to generate evidence that informs holistic decision-making and sustainable urban planning, integrating health and wellbeing with climate change mitigation and resilience.

This report details an interdisciplinary Environmental Flows (E-Flows) assessment of the Nam Songkhram River Basin in Northeast Thailand. The study examines the critical relationship between the Mekong River mainstream and the Nam Songkhram floodplain, emphasizing how the annual 'flood pulse' sustains high aquatic biodiversity and local livelihoods. The findings highlight a transition from natural wetland habitats to simplified ecosystems dominated by agricultural land and industrial tree plantations, specifically eucalyptus. The report argues that upstream flood control infrastructure is largely futile due to the dominance of the Mekong's hydrology and recommends a holistic, multi-stakeholder approach to basin management to prevent further ecological collapse.
