“…In this regard, hydro-economic models are emerging to provide useful analytical tools for assessing the effectiveness of water resource management at the basin level. The advantage of these models is that they are able to consider different dimensions of the system, such as agronomic, hydrologic, environmental, and economic conditions in order to provide a comprehensive and basin-specific assessment of water policy options in a climate change context [57]. Certainly, in a future likely characterized by a rise in extreme events, the effectiveness of water pricing policies may diminish if not integrated within a broader management framework that engages users through participatory systems [61].…”

“…On the other hand, there is a difference between annual crops (e.g., rice and corn) and perennials (e.g., fruit trees). In the latter case, the ability to respond to water scarcity is limited because these crops do not possess the same management flexibility as annual crops [57]. In addition, the type of crop can affect the elasticity of demand depending on the value of the crop itself.…”

“…This means that the water savings derived from increased efficiency do not extend to society as a collective benefit but are internalized by farmers, who tend to expand and intensify agricultural acreage, so to increase absolute water consumption. Another possible effect of improved irrigation technology is to incentivize the change in the crop portfolio towards highly profitable crops, thereby with unexpected results in terms of water use and rural development strategies [57].…”

Linking the improvement of water ecosystems to the use of economic concepts and instruments is one of the main innovations introduced by the EU Water Framework Directive (WFD). This should be achieved by Member States through an approach clearly linking measures and interventions to improve water ecosystems to the identified pressures on water bodies (i.e., the gap analysis) and a set of economic provisions. However, modest progress in the implementation of these provisions has been recorded over time. Therefore, this paper aims to shed new light on the current limits in the implementation of the economic analysis of the WFD, in particular in relation to the gap analysis, through a comprehensive review of grey and scientific literature on the topics of gap analysis, economic valuation of ecosystem goods and services, water pricing, and disproportionate costs of measures. General conclusions and recommendations of this analysis are that enhancing data quality, promoting consistency and interaction in economic analysis components, and embedding them pragmatically in decision-making procedures are crucial. The gap analysis plays a pivotal role in directing economic research towards relevant issues within the river basin and in guiding decision makers more effectively in the application of the economic analyses required by the WFD.

“…Water scarcity and droughts have emerged as significant issues, which are expected to be exacerbated by the impacts of climate change. Already, a considerable portion of the European population has been affected by water scarcity, posing a significant risk to the socioeconomic development in the region [43][44][45][46]. The increasing water scarcity and droughts across the European Union directly impact both citizens and economic sectors reliant on water, including agriculture, tourism, industry, power generation, and transport.…”

With the pressing challenges of water scarcity and pollution, achieving sustainable water management is imperative for promoting long-term development. Therefore, this paper aims to examine the socio-economic and cultural factors that shape the sustainability of water management strategies in Brazil and Portugal. This study highlights various factors that influence water management, including robust legal frameworks, socio-economic disparities, cultural practices, agricultural water usage, knowledge sharing, public participation, climate change resilience, water scarcity risks, industrial water consumption, and urbanization. By conducting a SWOT analysis of water management strategies, this research synthesizes information through an extensive literature review, encompassing the legal frameworks, policies, and implemented strategies in both countries. Additionally, it investigates comparative studies among Brazil, Portugal, and other European nations to facilitate the exchange of knowledge and experiences in water management practices. The findings of this study offer valuable insights into the strengths, weaknesses, opportunities, and threats associated with water management strategies in Brazil and Portugal, thereby guiding the development of tailored policies and strategies that foster sustainability in water resource management. Additionally, the research highlights the role of digital transformation in optimizing water management practices. By integrating socio-economic, cultural, and digital factors, this study contributes to effective and sustainable water management in Brazil and Portugal, ensuring responsible utilization and preservation of water resources.

The current situation of structural water scarcity due to the rise in demand, the reduction in supply as a consequence of climate change, increasingly frequent drought periods, and overall quantitative pressure on water resources creates a need for economic instruments to reduce the amount of water used, especially in the agricultural sector. Thus, water pricing and allocation quotas (proportional reduction of allocations) may be suitable tools to reduce demand or allocate scarce water resources. For a comparative analysis of the performance of these two measures, a Positive Mathematical Programming model has been developed, using the Guadalquivir River Basin as a case study. Additionally, the analysis takes into account the revenue generated from water pricing and the marginal cost of public funds. The results indicate that, from the farmer’s perspective, quotas result in smaller losses than water pricing. However, when considering water pricing along with the revenue generated from this measure, this mechanism would be more beneficial for society as a whole, since the taxes collected could be used for other purposes, albeit with efficiency losses measured by the marginal cost of public funds and the excess burden of taxation.
