Evolutionary Game Analysis for Grassland Degradation Management, Considering the Livelihood Differentiation of Herders

Abstract

Grassland degradation has become one of the most important ecological and environmental problems in the world, affecting the ecological balance of grassland and the welfare of residents. To reveal the impact mechanism of herders’ livelihood constraints on grassland degradation, and to explore the comprehensive management methods to ensure herders’ livelihoods and grassland ecological restoration, this paper constructed an evolutionary game model considering local governments and herders. It is found that the ideal stable equilibrium game can be achieved when certain conditions are met, that is, when the local governments actively regulate and herders moderate grazing, the grassland degradation caused by overgrazing can be reduced. The livelihood differentiation of herders significantly affects the stable equilibrium state of the evolutionary game. The local government’s regulation is the key to promoting moderate grazing of herders. The effect of incentive measures on the moderate grazing of herders is limited, while punishment measures can significantly restrict the excessive grazing behavior of herders. Policy support for household livelihood differentiation can effectively motivate herders to moderate grazing and achieve their survival and development needs to a greater extent through a non-grazing livelihood. The research results help decision-makers to formulate policies to combat grassland degradation, and promote the improvement of herders’ lives.

Evolutionary Game of Pesticide Reduction Management for Sustainable Agriculture: An Analysis Based on Local Governments, Farmers, and Consumers

“…Stakeholders can be defined as any group or individual that can influence, or be influenced by, the achievement of organizational goals [47]. The stakeholders involved in the process of rural environmental governance include farmers, government entities, consumers, agricultural enterprises, rural cooperatives, and many others [45,[48][49][50][51][52]. Many scholars have conducted research on rural environmental governance from different stakeholder perspectives.…”

Evolutionary Game Dynamics between Distributed Energy Resources and Microgrid Operator: Balancing Act for Power Factor Improvement

“…The study emphasized stakeholders' initial intentions and quality measure costs and highlighted the positive impact of governmental oversight, consumer feedback, and inspection penalties. In [9], the relationship between herders' livelihood constraints and grassland degradation was examined using an evolutionary game model involving local governments and herders. The paper highlighted that achieving an ideal equilibrium relied on proactive government regulation and moderate herder grazing.…”

Incentives for promoting climate change adaptation technologies in agriculture: an evolutionary game approach

“…Evolutionary game theory replaces the traditional game theory assumption of perfect rationality with nite rationality and learning ability, which asserts that both parties cannot nd the optimal equilibrium point in every game. It has been widely used in the study of multi-actor cooperation and policy analysis (Sun et al, 2022;Sun et al, 2021;Tian et al, 2022). Based on evolutionary game theory, we analyze the interactive game process between local governments and farmers in the context of promoting CCATs in agriculture and propose policy recommendations to promote adaptation to climate change in agricultural systems.…”
