CRiSTAL Forests User’s Manual

The CRiSTAL Forests User's Manual describes a desktop application used to identify and prioritize climate risks to forests, ecosystem services, and livelihoods. The tool employs a participatory approach, combining community consultations with scientific data to help project managers revise existing activities or design new ones that support climate adaptation. It specifically focuses on the role of forest ecosystem services—provisioning, regulating, and cultural—in creating vulnerabilities and supporting adaptive capacity. The manual outlines a structured process involving two main modules: understanding the local livelihoods and climate context, and evaluating the implications for project design, including optional assessments for greenhouse gas mitigation and REDD+ participation.

• CRiSTAL Forests is a decision-support tool that enables project planners to design activities supporting adaptation to climate variability and change, specifically for communities dependent on forest ecosystem services.
• The tool's analytical framework is based on the Millennium Ecosystem Assessment (2005), categorizing forest contributions into provisioning services (e.g., food, fuel), regulating and supporting services (e.g., climate regulation, erosion control), and cultural services (e.g., spiritual enrichment).
• The CRiSTAL Forests process is divided into two modules: Module A (compulsory) focuses on understanding livelihoods, ecosystems, and climate context; Module B (optional) evaluates project implications through revising activities, designing new ones, and assessing mitigation/REDD+ potential.
• The tool utilizes a participatory methodology, recommending that users conduct community consultations using Participatory Rural Appraisal (PRA) tools, such as resource and hazard mapping and vulnerability matrices, to capture local perceptions of climate risks.
• The tool helps users identify 'climate impact chains,' which trace how a climate hazard leads to a direct impact on forests, an indirect impact on ecosystem services, and a subsequent indirect impact on specific livelihood groups.
• CRiSTAL Forests includes a mechanism to evaluate and prioritize new project activities based on seven default criteria: support for vulnerable ecosystem services, broader vulnerability context, climate change considerations, long-term cost effectiveness, political feasibility, cultural appropriateness, and greenhouse gas emissions.
• The tool provides a preliminary assessment for participating in REDD+ schemes by evaluating quantitative factors (existence of national forest and GHG inventories) and qualitative factors (forest governance systems and international safeguards).
• The application of the tool typically requires between two to five days for preparation, consultations, data entry, and analysis.
