Mechanisms and pathways for reshaping the "water-energy-food" nexus and the synergistic development of livelihood transformation

How to break the resource and environmental constraints through effective resource management and promote the sustainable development of livelihoods is a key issue in current research. This paper first analyzes the interrelationship between the "water-energy-food" nexus and the livelihood transformation, as well as their respective connotations. On this basis, guided by the theory of complex adaptive systems, this paper systematically reveals the theoretical logic of their synergistic development from the "target dimension, subject dimension, spatial dimension, and temporal dimension", conducts an in-depth analysis of the practical dilemmas in their synergistic development, and further proposes practical paths for their sound synergy, while drawing on the theory of complex adaptive systems. The results show that: (1) The logical premise of the synergistic development of the "water-energy-food" nexus and the livelihoods transformation is the inherent consistency of the three major goals of economic development, ecological protection and social stability. In synergistic development, the adaptive behaviors of the government, enterprises and residents form a complex evolutionary mechanism based on their interests, and the complementary regional resources and spatial spillovers jointly shape the multi-level spatial pattern of synergistic development, while the nature of long-term development of the two highlights the dynamic evolutionary characteristics of synergistic development. (2) Influenced by multiple factors, the synergistic development of the "water-energy-food" nexus and livelihood transformation is confronted with practical predicaments such as the prominent contradiction between the goals of economic-ecological-social coordinated development, the difficulty in coordinating the interests of multiple stakeholders, regional development imbalance, and mismatch of time scales. (3) To promote the synergistic development of the "water-energy-food" nexus and livelihood transformation, it is necessary to: take technological progress as the core driving force, the concept of green development as the guiding principle, and industrial integration as the key nexus, thereby building a new economic development system characterized by the harmonious coexistence of "economy, ecology, and society"; clarify the positioning and division of labor among the government, enterprises, residents, and other multiple actors; adopt a multi-tiered system of constraints and balancing mechanisms to formulate regionally differentiated development pathways and promote cross-regional collaborative linkages; establish the main goals and actors for each stage of the "initialization, development, transformation, and synergization" process, as well as a mechanism for dynamic assessment and supervision of the entire life cycle.
