Purpose
This study aims to evaluate the characteristics of climate change in Yunnan minority areas and identify an effective path to promote sustainable livelihoods based on climate change.
Design/methodology/approach
Taking Yunnan Province as an example, based on the expansion of the traditional sustainable livelihood framework, the authors constructed a system dynamics (SD) model of sustainable livelihood from the six subsystems of natural, physical, financial, social, human and cultural and tested the accuracy and effectiveness of the model with data from Cangyuan County. By adjusting these parameters, five development paths are designed to simulate the future situation of the livelihood system and determine the optimal path.
Findings
Climate change has exacerbated the vulnerability of people’s livelihoods. In future, each of the five development paths will be advantageous for promoting sustainable livelihoods. However, compared with Path I (maintaining the status quo), Path III (path of giving priority to culture) and Path IV (path of giving priority to economic development) have more obvious advantages. Path II (path of giving priority to people’s lives) gradually increases the development rate by promoting people’s endogenous motivation, and Path V (path of coordinated development) is better than the other paths because of its more balanced consideration.
Originality/value
The analytical framework of sustainable livelihoods based on the characteristics of minority areas is broadened. By constructing a SD model of the livelihood system, the limitations of traditional static analysis have been overcome and a development path for promoting sustainable livelihoods through simulation is proposed. This study offers a theoretical framework and reference method for livelihood research against the backdrop of climate change and a decision-making basis for enhancing climate adaptability and realizing sustainable livelihoods.
As an essential regional planning policy, poverty alleviation relocation has a significant impact on the regional economy, environment, and social well-being and is critical for sustainable development. Based on the development of minority areas in Yunnan, this study improves the traditional sustainable livelihood analysis framework and constructed a livelihood capital evaluation system including natural, physical, financial, social, human, and cultural capital. Furthermore, the measurement standard of sustainable livelihoods is proposed, which requires not only the enhancement of livelihood capital but also the coupling and coordinated development of all capital components. Based on the data of Menglai township from 2015 to 2021, this study estimates that farmers’ livelihood capital has increased after relocation, and the level of coupling and coordination has improved. Still, it has yet to reach extreme coordination. Hereafter, the theoretical framework of internal and external factors affecting livelihood capital is constructed, and the influencing factors of livelihood capital are obtained through regression analysis. This study provides a new tool for evaluating livelihood capital in minority areas, obtains new findings on the sustainable development of farmers’ livelihood capital after poverty alleviation relocation, and expands a new perspective for studying the influencing factors of livelihood capital.
