Solar-powered Irrigation Systems (SPIS)

SPIS Study // Impact of Solar Pumping Irrigation Systems in Tunisia

This case study analyzes the impact of solar-powered irrigation systems (SPIS)on the groundwater use as well as its impact on a socio-economic level in Tunisia. It is based on interviews with a sample of Tunisian farmers and provides recommendations to promote the sustainable use of the technology. The study is published in French with an executive summary in English.

Irrigated agriculture plays an important role for Tunisia´s economy, its trading economy and food security. It is highly related to the availability of groundwater, in particular in the central and southern areas of the country. The cost of off-grid pumping is increasing due to the continuous fade-out of diesel subsidies. The use of SPIS has thus become economically viable compared to diesel systems.

The study is part of an evaluation mission of the Water-Energy-Food Nexus (WEF Nexus) in Tunisia commissioned by the Nexus Regional Dialogue in the MENA region, co-funded by the European Union and the German Federal Ministry for Economic Cooperation and Development (BMZ) and jointly managed by EU DEVCO and GIZ. This study has been carried out in close collaboration with the Food and Agriculture Organization of the United Nations (FAO), through its project “Realising the potential and managing the risks of solar irrigation in the Near East and North Africa”.

Publication // A 40-year review of food–energy–water nexus literature and its application to the urban scale

By Newell, J. P., Goldstein, B., & Foster, A. (2019). What research exists to date on the FEW nexus? How have scholars conceptualized these interactions at the urban scale? What are some promising approaches? Where are the research gaps? To answer these questions, this paper conducts a quantitative review of the academic literature on the FEW nexus (1399 publications) over more than four decades (1973–2017), followed by in-depth analysis of the most influential papers using an evaluation matrix...

Policy Brief // Introducing Societal Metabolism Analysis via ‘MuSIASEM'

By Kerry A. Waylen, Kirsty L. Blackstock, Keith B. Matthews, Mario Giampietro. This paper introduces the Societal Metabolism Analysis, which is at the heart of the MAGIC project. It offers a way to characterise patterns of consumption and production associated with the metabolic patterns of different systems, thus enabling analysts to look across sectors and scales. It was developed by "MAGIC Nexus", a project by the European Union's Horizon2020 research and innovation program.
