The water-energy-food nexus has emerged as a productive discourse and methodology in academic research, science-policy dialogues, and development agendas. While the nexus provides a robust framework for interdisciplinary study, research remains focused on synergies and tradeoffs in resource "security" and fails to adequately acknowledge the environment as the set of natural processes underpinning the nexus, particularly interactions among water, energy, and food. Resource security as a reductionist discourse does not address the limitations and potential of natural processes and the dynamic nature of human processes, especially adaptation to global changew A review of recent literature highlights the need to redefine the nexus to fundamentally incorporate the environment, and, drawing on social-ecological systems thinking, to integrate considerations of adaptive capacity and resilience within nexus theory and practice. Future directions for this line of inquiry include identifying feasible ways of assessing the nexus in the context of dynamic social and ecological systems, and implications that adaptive actions have across resource-use sectors and the environment. A more holistic nexus framework enhances our options to manage environmental interactions, human activities, and policies to adapt to global-change uncertainties.

This study examined local people's perception of climate change and its impacts on their livelihoods, and identified key opportunities and threats arising in four Village Development Committees in the high mountains of Rasuwa District, Nepal. The local people are still heavily dependent on agriculture and livestock for their food security and livelihoods, despite the involvement of a significant proportion of households in non-agricultural income-generating activities, such as tourist services and labour work in other areas (outmigration). In agriculture, farmers mainly cultivate traditional food crops such as millets, buckwheat, local beans, and barley. They also cultivate rice, potato, and vegetables. Agriculture is mainly rainfed with a few exceptions of micro-irrigation systems fed by springs and snow-melt water. The impacts of climate change are mixed to date: changes in patterns of snowfall and snowmelt, rainfall, and temperatures are having both positive and negative impacts. Households are adapting to this changing climate through changes in their cropping patterns, integration of livestock with agriculture, and adoption of non-farm income activities. There are also new opportunities coming up at the study sites such as new markets for vegetables, traditional crops, and livestock.
