A "solution-based bottom-up approach" involves addressing problems from the ground up, where individuals affected by the issue are included in the decision-making process. Synonyms for this approach include participatory decision-making, grassroots problem-solving, community-based solutions, locally-driven solutions, collaborative problem-solving, and decentralized decision-making. The idea behind this approach is to foster greater community involvement and participation in addressing complex social, economic, and environmental issues. By involving those at the grassroots level, a more comprehensive understanding of the problem and its impact can be achieved, leading to more effective solutions. Ultimately, the goal is to empower communities and individuals to take ownership of the issues that affect them and actively participate in creating viable solutions.
