SIGMA Nexus project has participated in the XVII Congress of the European Association of Agricultural Economists (EAAE) with a poster presention. EAAE Congress 2023 took place in Rennes, France from August 29th to September 1st and focused on agri-food systems in a changing world: Connecting science and society.

Developing Farm-Level WEFE Nexus Composite Indicator: Application For Olive Producers In Crete

(Olha Halytsia, Maria Vrachioli, Johannes Sauer)

 

Given the increasing scarcity of natural resources and raising environmental concerns, the assessment of farms’ performance has received special attention. The nexus approach is particularly useful for such type of analysis since it reflects complex interconnections among the sectors of water, energy, food and environment (WEFE). One way to explicitly place agricultural production within the WEFE Nexus is to develop a composite indicator that will reflect interlinkages between agricultural production and the water, energy and environment pillars of the Nexus. Our study aims to operationalize WEFE Nexus and contributes to the existing literature by proposing a methodology to calculate the farm-level WEFE Nexus composite indicator using endogenous weights for aggregation. In addition, we develop a web application “WEFE Nexus Index calculator”, which allows users to estimate technical efficiency levels and calculate composite indicator values based on uploaded farm-level data.
