How agricultural research can navigate the perfect storm
The Water-Energy-Food Nexus Blog Series
Delivering water, energy and food for all in a sustainable and equitable way is a major challenge faced by society. The water-energy-food nexus concept aims to address this by better understanding how interactions between water, energy and food are shaped by environmental, economic, social and political changes and how the synergies and trade-offs among them can be better planned and managed. The Water-Energy-Food Nexus Knowledge-Action Network is a network of people and organisations which fosters transdisciplinary research and communicates the importance of holistic system approaches across water, energy and food systems. Acknowledging that the nexus concept is often described as overly academic and not practical on the ground, the Water-Energy-Food Nexus Knowledge-Action Network is organising this blog series to illustrate the role of the nexus concept in addressing local and national challenges of sustainable and equitable access to resources. Understanding the perceptions and entry points with which local and national stakeholders can engage with the nexus concept is key to further implementing nexus approaches, especially in the Global South.

How agricultural research can navigate the perfect storm
By Adam Hunt, Izabella Koziell and Claudia Ringler
The world is about to face the perfect storm. Population growth, rising incomes and urbanization mean growing demand for food, energy and resources. At the same time, we harm our ability to meet those needs by degrading our water, biodiversity and soils. Meanwhile, climate change and social inequality intensify all of these challenges, leading to a downward spiral of choices that worsen degradation and pollution. This confluence of challenges presents serious risks to global food and nutrition security.
Regrettably, in our efforts to tackle this complexity, we rarely find traction at the scales needed. Solutions need to work across scales: from farm to national to global. But also across sectors: food, water, energy and others. We are, after all, on a global campaign to meet our Sustainable Development Goals (SDGs), most of which are intertwined with food. Thus, more researchers are considering entire systems. The Water-Energy-Food (WEF) Nexus is one such approach, helping ensure researchers move beyond silos and understand that actions in any one area usually impact other sectors.
We are the authors of unintended consequences
Too often, meeting one need harms our ability to meet others. To date, agricultural research has delivered field level innovations: we develop new seeds or new irrigation or soil management techniques. But typically these include only partial assessments of systems or landscape level impacts. We see similar toxic errors in energy, water and other development projects where agriculture is deprioritized – and ultimately degraded.
Consider India, where advances in groundwater pumping technology and government subsidies helped farmers meet short-term irrigation needs, but dangerously depleted groundwater levels. Or large hydropower dams: they may quench our thirst for energy, but often harm food production and fish populations – and hence vulnerable communities.
A Nexus approach helps manage such tradeoffs. One potential success is solar irrigation. Solar pumps can replace greenhouse gas emitting diesel pumps. But low operating expenses risk over-pumping, depleting groundwater. To avoid this, the CGIAR Research Program on Water, Land and Ecosystems (WLE) and partners supported Indian farmers to form cooperatives to sell excess energy back to the grid. This prevented over-pumping, while shoring up farmer income. The scheme is now set to scale up in Gujarat, while researchers are also strengthening groundwater governance through simulation games in Indian villages.
What about other impacts of solar irrigation? Through the International Water Management Institute (IWMI), we’ve developed maps that calculate an area’s solar suitability, assessing risks such as those to soils (by assessing slopes) or ecosystem services (by assessing water availability). And we’re expanding this analysis to all of Sub-Saharan Africa, also incorporating food security considerations and cost-benefit analyses.
Finding such solutions was at the heart of the discussions on tradeoffs and synergies among SDGs at Science Forum 2018, organized recently by CGIAR’s Independent Science and Partnership Council (ISPC). Our session brought together scientists, practitioners, donors and other experts to figure out why agricultural research has often failed to consider interactions or scale up solutions – and how we can do better.
How can research help harness all this complexity?
Our experts identified room for improvement. While we’ve made progress in developing tools and capacity for decision makers, we still need to reduce unintended negative consequences and generate synergistic benefits – this is not easy and not common practice.
The first step is improving how we prioritize our research-for-development activities. We need to better balance the focus on agricultural technologies with investment in systems approaches. We should also do more to look at failures – how can cases where synergies and tradeoffs were not well considered help us prioritize next activities?
Secondly, we need to discover better ways of supporting decision makers to make ‘best bet decisions.’ Integrated modelling will continue play a role but in the absence of perfect data, we need methods to better deal with complexity and uncertainty, and assess benefit/costs of cross-sector approaches. Researchers may also have to find ways to make decisions with imperfect or incomplete information – sometimes settling for “good enough.”
Third, we need to improve research design. All agriculture research projects need to account for impacts and feedback effects on multiple outcomes – health and nutrition, energy, greenhouse gas production, ecosystems. Research programs need trans-disciplinary, intersectional, mixed methods. We need to consider impacts at various scales: from farm to global and everywhere in between. And we need to prioritize strong risk assessments before we hit the ground.
Finally, we must improve how we measure progress. Projects must be evaluated on a broader set of SDG-related indicators. Irrigation projects need to measure impacts on nutrition, soil, gender and more – just as breeding initiatives need to track how new seeds impact water, biodiversity and social equity. We need indices that can compare outcomes across projects and landscapes. And let’s assess distributional impacts – how does an intervention impact the Global South vs. North? Rural vs. urban? Women vs. men? We need to build resilience on multiple levels – across natural resources, in the face of climate change, and in our economic and social spheres. These need to be front and center when measuring progress.
As we sail through this storm, we seem to be heading in the right direction. However, we can expect rough seas as we grapple with these complexities. Solutions rely not just on better partnerships, but on creating and using models and indicators that allow us to measure the tradeoffs and synergies inherent in every decision. Let’s hope we can move on the right partnerships, approaches and tools to ensure we see some calm in the midst of the storm.
