水-能源-粮食关系正在作为实现可持续发展的一个概念工具加以推广。然而，实施“关联思维”的框架未能明确或充分纳入可持续生计观点。鉴于生计是实现可持续发展的关键，这是违反直觉的。在本文中，我们提出了一个关键的审查关系的方法，并确定与可持续生计的理论和实践的潜在联系，加深我们的理解，人口和自然环境之间的相互关联的动态。在此基础上，我们探讨了“环境生计安全”的概念，其中包括自然资源供应和人类对环境的需求之间的平衡，以促进可持续发展-并制定一个综合的关系，生计框架，检查系统的环境生计安全。其成果是建立了一个综合框架，该框架能够通过在多个空间尺度和机构层面核算水、能源和粮食对生计的影响，来衡量和监测整个系统的环境生计安全。我们预计，这种整体方法不仅将为实现国家和区域可持续发展目标做出重大贡献，而且还将有效促进个人和社区在地方和全球发展议程中的平等。(C)2015作者由Elsevier Ltd.发布。这是CC BY-NC-ND许可证下的开放获取文章（http：//creativecommons.org/licenses/by-nc-nd/4.01）。
The water-energy-food nexus is being promoted as a conceptual tool for achieving sustainable development. Frameworks for implementing nexus thinking, however, have failed to explicitly or adequately incorporate sustainable livelihoods perspectives. This is counterintuitive given that livelihoods are key to achieving sustainable development. In this paper we present a critical review of nexus approaches and identify potential linkages with sustainable livelihoods theory and practice, to deepen our understanding of the interrelated dynamics between human populations and the natural environment. Building upon this review, we explore the concept of 'environmental livelihood security' which encompasses a balance between natural resource supply and human demand on the environment to promote sustainability - and develop an integrated nexus-livelihoods framework for examining the environmental livelihood security of a system. The outcome is an integrated framework with the capacity to measure and monitor environmental livelihood security of whole systems by accounting for the water, energy and food requisites for livelihoods at multiple spatial scales and institutional levels. We anticipate this holistic approach will not only provide a significant contribution to achieving national and regional sustainable development targets, but will also be effective for promoting equity amongst individuals and communities in local and global development agendas.
