Design for Conservation (D4C) is a methodology that enables participative problem-solving for environmental conservation and sustainability challenges. This toolkit enables participants to address complex challenges in a creative, non-linear way, taking into consideration multiple stakeholder points of view - human and nonhuman - and the complex interactions between emotional, spiritual, and scientific approaches. The methodology balances work and play, fostering trust among participants, and creating a safe space for multiple world views to co-exist.
