The article discusses a toolkit for assessing wetlands, which are crucial for many people's livelihoods and home to diverse wildlife. Traditional methods of assessing wetlands often undervalue them, leading to their loss. The toolkit, developed through case studies in Cambodia and Tanzania, integrates biodiversity, livelihood, and economic assessments to show the full value of wetlands. This helps bridge the gap between different sectors involved in wetland conservation and development planning. The toolkit provides practical methods for collecting information that can be used by those working in wetland conservation and planning.
