The current study is an attempt to provide a tool that can be used to manage sustainable rural livelihoods more effectively. This tool also avoids the harm of resources wastage as much as possible. The indicators of the sustainability of livelihood are investigated in this paper by reviewing the past and recent studies. According to the literature reviews of sustainable development, the sustainability of livelihood can be included in the main categories of rural assets. Therefore, based on the seven years fieldwork experience of this paper's authors in working with local rural communities and interviews with specialists through a snowball method the Participatory Rural Appraisal method is identified as the best way for the extraction of indicators. As a result of the investigations in this paper, the participatory assessment model (PAM) is proposed by using design thinking techniques. The possibility of converting qualitative values into quantitative ones is provided by drawing of hypothetical positions and mathematical formulas. This model attempts are made to achieve livelihood sustainability as a perspective. Additionally, development projects aimed at conservation in the face of climate change can use this model to assess their own perspective. Using PAM can also help practitioners in this area to make more realistic planning.
