Case study // The Republic of Mauritius

Mauritius has recently developed a remarkable tourist and financial sector. Nevertheless the agricultural sector is still strong: The sugarcane production uses a considerable part of the water resources. This case study focusses on the options of reaching food and energy sufficiency on Mauritius by changes in the agricultural sector.

 

External constraint: Shortage of suitable land - A large-scale move from existing sugarcane plantations to food crop production for internal consumption is subject to geographic constraints, including soil type, slope, and hydrological characteristics. The traditional crop mix cultivated right now in Mauritius cannot be simply extrapolated to the entire area presently under sugarcane. Using the existing crop characteristics (but obviously other crops and varieties could be introduced) we assess that the existing crop mix can only be expanded on 64.6% of the agricultural area. Maize could perhaps be grown on some of the rest (another 22% of the total), given the demand for this cereal to feed chicken in Mauritius is large, leaving the rest of the area (13.4%) to sugarcane. This new crop mix, with a dramatic reduction of sugarcane, will positively affect water metabolism, reducing the consumption of water of the agricultural sector.

In this second scenario the shift from sugarcane plantations to food cultivation (taking into account internal and external constraints) will not significantly improve the level of food self-sufficiency for Mauritius. The internal coverage of the food requirement will increase from 16% to 33% of the total.

Nexus Blog // Understanding the Water-Energy-Food Nexus in a warming Climate

In this article, the authors explore what the WEF Nexus is, how to minimize trade-offs and maximise co-benefits within it, and what opportunities it offers to address the challenges of a changing climate. They further draw on ongoing research in Tanzania’s Rufiji River Basin – a case that exemplifies key issues in the WEF nexus – where ambitious development plans cut across several sectors and could be severely limited by future climate change.

Call for Nexus Research Proposals // Call with South Africa on Water-Energy-Food Nexus

This call marks the start of a new cooperation programme with the South African National Research Foundation (NRF) and falls under the Merian Fund. The programme aims to further stimulate joint, impact-oriented research between Dutch and South African researchers. The first call for proposals focuses on the WEF nexus within major societal challenges. The deadline for submission is 26 September 2019.
