Capacity building in communities is the process of enhancing the skills, knowledge, resources, and organizational abilities of individuals, groups, and institutions to empower them to effectively address their challenges and achieve sustainable development. It is essential because it fosters self-reliance, strengthens local leadership, and promotes collective problem-solving, enabling communities to take ownership of their development. By investing in capacity building, communities can harness their potential, adapt to changing circumstances, and drive long-term progress. Ultimately, it leads to improved social, economic, and environmental outcomes, creating resilient, inclusive, and thriving communities equipped to meet both current and future needs.
