This collection critically engages the resource use nexus. Clearly, a nexus-approach to resource policy, planning and practice is essential if sustainable development goals are to be met. In particular, in an era of climate change, an integrated approach to water, energy and agriculture is imperative. Agriculture accounts for 70% of global water withdrawals, food production accounts for 30% of global energy use and a rising global population requires more of everything. As shown in this collection, scholars of resource development, governance and management are 'nexus sensitive', utilizing a sort of 'nexus sensibility' in their work as it focuses on the needs of people particularly, but not only, in the global South. Importantly, a nexus-approach presents academics and practitioners with a discursive space in which to shape policy through research, to deepen and improve understandings of the interconnections and impacts of particular types of resource use, and to critically reflect on actions taken in the name of the 'nexus'.

In 2018, the city of Cape Town faced the prospect of reaching 'day zero', that is a combination of natural and human-made factors leading to the complete collapse of its municipal water supply. While the rains eventually fell and a major disaster was averted, the fear of running out of water looms large in the psyche of residents in many cities around the world. Water is a non-substitutable, essential, finite and fugitive resource. It is the lifeblood of human endeavour. Cities, through global processes such as Agenda 2030 and forums such as ICLEI exchange best practices for achieving water security. These forums also are collective social spaces occupied by civil society organizations who share strategies and tactics, and the private sector, who compete for markets and contracts, promoting patent-protected technologies. It is these groups - states, civil societies, private sectors - coming together who determine who gets what water, when, and where. It is the job of academics to understand the how and why, and of (academic-)activists to fight for equity of access and sustainability of use. Evidence drawn from around the world and over time consistently shows that water flows toward money and power. Outcomes are too-often socially inequitable, environmentally unsustainable and economically inefficient. How to shift existing processes toward improved practices is not clear, but positive outcomes do exist. In this collection, we compare and contrast the challenges and opportunities for achieving urban water security with a focus on 11 major world cities: Bangalore, Beijing, Cairo, Cape Town, Chennai, Istanbul, Jakarta, London, Melbourne, Sao Paulo and Tokyo. Through the theoretical, conceptual and practical insights provided in these case studies, our collection constructively contributes to a global conversation regarding the ways and means of 'avoiding day zero'.

This project breaks disciplinary silos by bringing those who work in climate finance and policy together with development scholars and practitioners to share lessons, understanding, and research with an overall goal of making a contribution to the climate change field so that those at the community level benefit from the multitude of programmes designed for climate impacts. For some 70 years, International Development specialists have been developing programs and delivering funds to those who most need assistance. There is a wealth of knowledge to be uncovered by examining the international development industry for those who are now tasked with delivering climate finance. The academic, policy, and practitioner communities have spent decades researching, examining, and analyzing both development policies and finance independent of each. This volume will seek to bring that research together.
