Climate Uncertainty Modelling in Integrated Water Resources Management: Review

Abstract

Integrated water resources management is exposed to the effects of several risks (climatic, socio-economic, and political). Currently, climate change represents one of the greatest risks for many countries around the world and the agricultural sector in particular. In the literature, climate change is sufficiently researched but there are scarce studies that deal with the theme of risk in agricultural water management and in particular the management under climate change. In the paper, we first define out the characteristics and particularity of climate change risk and then we point the different approaches and methods for taking into consideration for climate change risk in the integrated water resources management models for the agriculture sector. In this work, we aim to appraise the quantification of uncertainties in systems modelling in watersheds and discuss various water resource management and operation models.

Copulas and hydro-economic models for assessing the impacts of climate change in irrigated agriculture

“…Over the past few decades, HEMs have been devised to evaluate the impacts of climate change and suggest adaptation strategies. These models, specifically designed for regional water resource management, confront various uncertainties associated with climate change that accumulate during the decision-making process [3]. Effectively addressing these uncertainties becomes a pivotal task in water resource modeling, aiming to enhance the formulation of more efficient policies for water resource management.…”

“…In the context of climate change, extreme weather events pose significant threats to agricultural systems, with agricultural drought risk being a prominent concern [3]. This type of risk, characterized by the likelihood of crop failure, can lead to substantial economic losses [31].…”
