“…Small wetlands and riparian ecosystems have formed along some irrigation conveyance systems, which would also be threated if water is reallocated from agriculture. Llop and Ponce‐Alifonso have taken a first step toward establishing the trade‐offs between economic benefits and the environment under different reallocation schemes using a computable general equilibrium (CGE) model with an ecological sector.…”

The growing number of areas facing water scarcity necessitates adaptive water management strategies beyond traditional water supply and demand management methods, which are becoming increasingly difficult in many regions. Water reallocation offers a flexible water management approach to mitigate water scarcity under changing socioeconomic, climatic, and environmental conditions. In spite of the numerous benefits of reallocating water between users, examples of successful water transfers are relatively sparse and the expected benefits are rarely met in full due to several complex impediments. This study overviews the current body of water reallocation literature, with a particular focus on the key barriers to wider implementation of water reallocation. We argue that to overcome these obstacles a more interdisciplinary approach to water reallocation should be advanced that couples developments in the natural sciences and engineering disciplines with current water reallocation scholarship, which is predominately rooted in the social sciences. Many examples of water transfers from around the world are used to illustrate both the benefits and challenges associated with reallocation, as well as to identify measures to overcome some of the major difficulties. We conclude by calling for an integrated research platform that focuses on supporting both voluntary and nonvoluntary forms of water reallocation; however, a greater emphasis should be on nonmarket means of water transfer since it is more feasible for many regions where water rights are not well defined and institutional capacity is insufficient.

“…Water is not only important as an input but also as an environmental resource. For instance, specifying an ecological sector that absorbs the difference between total water endowment and water use by consumers and producers enables an evaluation of the environmental implications of different supply and demand side water policies [e.g., Llop and Ponce‐Alifonso , ].…”

An integrated economic model of multiple types and uses of water

Water scarcity is an increasing problem in many parts of the world and the management of water has become an important issue on the political economy agenda in many countries. As water is used in most economic activities and the allocation of water is often a complex problem involving different economic agents and sectors, Computable General Equilibrium (CGE) models have been proven useful to analyze water allocation problems, although their adaptation to include water is still relatively undeveloped. This paper provides a description of an integrated water-focused CGE model (STAGE_W) that includes multiple types and uses of water, and for the first time, the reclamation of wastewater as well as the provision of brackish groundwater as separate, independent activities with specific cost structures. The insights provided by the model are illustrated with an application to the Israeli water sector assuming that freshwater resources available to the economy are cut by 50%. We analyze how the Israeli economy copes with this shock if it reduces potable water supply compared with further investments in the desalination sector. The results demonstrate that the effects on the economy are slightly negative under both scenarios. Counter intuitively, the provision of additional potable water to the economy through desalination does not substantively reduce the negative outcomes. This is mainly due to the high costs of desalination, which are currently subsidized, with the distribution of the negative welfare effect over household groups dependent on how these subsidies are financed.

“…To achieve the goal of effective water-saving, the first condition is to make reasonable water resource management policy design and policy choice. However, water resource management is not simply a natural science issue, but also a social science issue (Llop & Ponce-Alifonso, 2012). Water resource management policy will have a variety of complex effects on macro-economy, resources and environment, and policy stakeholders.…”

Water policy and regional economic development: evidence from Henan province, China

et al. 2021

With the rapid advance of industrialization and urbanization and the intensified impact of global climate change, the contradiction between the global water shortage and economic growth has become prominent. This paper, taking Henan province as an example, analyzed the influence of water resource policy on regional economic growth through a calculable general equilibrium model and further discussed the relevant policy recommendations. The results showed that the improvement of water supply, water efficiency and water technology could promote the growth of the regional economy and result in a positive effect on regional GDP, employment and resident income. However, the rise of water price has a negative impact on regional economic development, mainly reflected in regional GDP, employment and household income. The improvement of water price, water efficiency and water conservancy technology would lead to a decrease in regional water consumption, while only the increase of the water supply would lead to an increase in water consumption. Accordingly, the paper put forward policy suggestions, such as accelerating the improvement of water conservancy facilities, establishing a reasonable water price mechanism and actively exploring experience in water conservation and emission reduction.
