Abstract
Water scarcity is a major constraint at national level, under the combined effects of irregular rainfall, the country’s growing needs to respond to demographic pressure and the call of competing economic sectors (agriculture, industry, drinking water, tourism, etc.). This situation is further exacerbated by the impact of climate change, so optimization and sustainable water management are a necessity. Within this framework, this research work aims to measure the performance of producers of red fruit farms at the Loukkos perimeter through an empirical analysis of their technical efficiency and efficiency of water use. To achieve this, a deterministic production frontier model (with a production technology represented by a translog functional form) has been specified using the software FRONTIER 4.1, allowing both the estimation of farm efficiency scores and the identification of the explanatory factors for technical inefficiency. Then the estimation of water use efficiency scores using the Reinhard derivative has been measured. Survey data collected from a sample of 40 raspberry and 20 blueberry farms in the Loukkos area were used for this purpose. The results show that a minority of the farms selected are below their production frontier and are characterized by technical inefficiency. The average technical efficiency is 91%, indicating a level ranging from 60% to 99% for raspberry and an average of 91% ranging from 80% to 99% for blueberry. Some of these producers could increase their technical efficiency without having to increase their input volumes. The technical efficiency of water use is higher than 80% for raspberry, for blueberry more than 98%. On the other hand, the economic efficiency of water use scores for both crops is high (99%). As regards the analysis of the determinants of the technical efficiency and efficiency of water use they were analyzed with GRETL using Tobit model, it follows that variables such as age of farm managers, level of education, and planting age for blueberries are significant and influence positively the level of technical efficiency and technical efficiency of water use in raspberry and blueberry operations. These various results were used to identify implications, in terms of development measures, with a view to improving the performance of these farms.
