Climate change is a critical global challenge that significantly influences land use, crop production, and ecosystem sustainability. The dynamics of climate change and land suitability assessment are examined in this chapter, with a focus on how biophysical, ecological, and socioeconomic aspects are integrated into decision-making processes. Using technologies like Geographic Information Systems (GIS), remote sensing, and machine learning techniques, the chapter explores methodological developments in land suitability modeming. It features case studies from several geographic locations that show how changing precipitation patterns, temperature, and extreme weather events alter the suitability of land for forestry, agriculture, and other land uses. The topic of discussion also includes how participatory methods can be used to involve stakeholders and encourage resilience in land-use planning. By addressing the challenges and opportunities associated with climate change, this chapter provides actionable insights and frameworks for researchers, policymakers, and practitioners aiming to balance development and sustainability in a rapidly changing environment.
