By Andrew Burger. Researchers around the world are discovering a variety of benefits resulting from installation of photovoltaic (PV) solar energy systems on farms and ranch lands, as well as the use of solar energy to power pumps for irrigation systems. The author analyses various positive effects of the use of solar-power energy in the agriculture sector both, in countries in the Global North and the Global South. Examples are longer growing seasons, more water-efficient biomass and a...// more
By Stacy D. VanDeveer, Raimund Bleischwitz and Catalina Spataru. The unabated growth of natural resource consumption raises risks that we will outstrip the capacities of ecosystems and governance institutions. At the same time, to achieve important global goals related to poverty alleviation, public health, equity and economic development such as those embodied in the United Nations Sustainable Development Goals (SDGs), we will simultaneously need more resources and better management of natural...// more
By Harris Moysiadis. This article explores how the Internet of Things concept could facilitate the implementation of the water, energy and food nexus. The author introduces the H2020 project “Innovative eco-technologies for Resource Recovery from Waste-water” (INCOVER). It is argued that platforms and technologies offered by the Internet of Things could have a profound role in quantifying, visualising and sharing important data that would help state and non-state actors to plan, develop and...// more
By Kevin Sliman and Grace Lifsted. Penn State researchers from all disciplines are getting involved in the Food-Energy-Water (FEW) nexus. Considering the intricate nature of FEW, many researchers believe that an interdisciplinary approach is critical. This articles introduces interdisciplinary research projects and collaborations at Penn State University.// more
By Claudia Ringler, Adam Hunt and Izabella Koziell. In their article, the authors discuss the challenges and opportunities of implementing the Nexus approach from the perspective of agricultural research. It is argued, that all agriculture research projects need to account for impacts and feedback effects on multiple outcomes – health and nutrition, energy, greenhouse gas production, ecosystems. Solutions rely not just on better partnerships, but on creating and using models and indicators that...// more
By Kate Zerrenner (EDF) and Dylan Dupre (CalCom Energy). Across the US, farmers face unrelenting pressure to conserve both water and energy. From California to Texas, recent droughts and declining groundwater levels require more pumping to provide irrigation water for crops. Pumping water takes energy, as do many other precision agriculture tasks involved in running a successful farm today. This symbiotic relationship between water and energy use – often called the energy-water nexus – is taking...// more
By Anders Jägerskog. Groundwater is fast disappearing in the Middle East and North Africa region. Under a business-as-usual approach to the use of these scarce resources, it is estimated that they will be gone in about 30 years. This will have a devastating impact on the communities and livelihoods that rely on this water.// more
By Diego Juan Rodriguez. Worldwide, the majority of wastewater is neither collected nor teated. Wastewater is a valuable resource, but is often seen as a burden to be disposed of. This perceptions needs to change. In this blog post from the World Bank's Water Blog, Diego Juan Rodriguez discusses the need for transitioning from a linear model to a circular one focused on reducing water use and consumption and promoting the reuse, recycling, restoration and recovery of water resources.// more
"I do not think we need to abandon the Nexus concept," says Oliver Taherzadeh. "The Nexus agenda has sparked an interesting and necessary discussion around the reconciliation of environmental goals. However, to date, the theoretical and empirical contribution of the Nexus agenda offer a blunt tool to navigate this problem space."// more
By Kate Zerrenner and Jaclyn Rambarran. San Antonio is a unique place that should be honored in Texas and beyond. In addition to its strong Hispanic heritage, the city boasts a large military population, straddles the border between eastern, western, and southern U.S., and claims to be the birthplace of breakfast tacos. This growing city also has a powerful role to play in the future of Texas and the United States in terms of climate change and air quality, as evidenced by its initiatives around...// more
The Nexus Blog is a series of articles published during the Bonn2011 Nexus Conference. It aimed at creating debate and discussion around new approaches to address the critical resource challenges we face, which consider the interconnections within the water, energy and food security nexus.
In order to harness the voices of stakeholders around the nexus approach, the Stakeholder Forum for a Sustainable Future coordinated the Nexus Blog and invited a wide range of contributors with experience and expertise in at least one of the three nexus areas to submit an entry to the Nexus Blog.
The Nexus Blog is closed now.
