Managing Water Supply and Demand to Achieve Economic and Environmental Objectives: Application of Mathematical Programming and ANFIS Models

Abstract

Integrated management of water supply and demand has been considered by many policymakers and due to its complexity, the decision makers have faced many challenges. In this study, we proposed an efficient framework for managing water supply and demand in line with the economic and environmental objectives of the basin. To design this framework, a combination of ANFIS and multi-objective augmented ε-constraint programming models and TOPSIS were used. First, using hydrological data from 2001 to 2017, the rate of water release from the dam reservoir was estimated with the ANFIS model; afterwards, its allocation to agricultural areas was performed by combining multi-objective augmented ε-constraint models and TOPSIS. To prove the reliability of the proposed model, the southern Karkheh basin in Khuzestan province, Iran, was considered as a case study. The results showed that this model is able to reduce irrigation water consumption and improve its economic productivity in the basin.

Evaluation of water-energy-food-environment-agricultural economic growth nexus integrated approach to achieve sustainable production

“…Iran is a country that has faced a crisis of surface and groundwater resources in the past decades due to population growth and economic development, as well as phenomena such as drought and land use change (Boazar et al, 2019;Mardani Najafabadi et al, 2022a). In addition, in Iran, the consumption of chemical fertilizers and pesticides in the agricultural sector is at a very high level, and concerns about the harmful effects of these chemicals on human health and the release of environmental pollutants are signi cantly increasing (Hashemi et al, 2012; Iran Food and Drug Administration, 2016; Mardani Najafabadi et al, 2022b).…”
