Focus

For practical purposes, the Guadiana case study is divided in two sections:

The Upper Guadiana basin presents a paradigmatic case of a semiarid region where intensive groundwater use for irrigation has helped transform a largely poor rural region into a prosperous agricultural and industrial center. From an economy based on growing wheat and vines and sheep rearing, the area has experienced a transformation into what is today: a vibrant and economically viable region that no longer depends exclusively on agriculture. However, some problems have arisen as a result of uncontrolled groundwater development. These essentially refer to the conflict between farmers social and economic development and the environmental value of groundwater-dependent ecosystems. The UCM team focuses on this part of the case study.

The Transboundary part of this case study focuses mainly on the international relationships for river management ruled by the Albufeira Convention, signed in 1998 by Spain and Portugal. The Convention is widely regarded as a successful example of international cooperation. The Guadiana basin is Portugal's pilot catchment for the implementation of the EU's Water Framework Directive and hosts the Alqueva dam, the largest in Europe. The main objective of this development is to contribute to the social and economic welfare of the Alentejo region. ISQ, Sustainable Development Unit, coordinates this part of the case study.

NeWater Research

As shown in the baseline report by the research team, no formal adaptive management strategies as such exist in the Guadiana river basin to date. The NeWater project is expected to create awareness for the need of such practices and to develop tools to support stakeholders when approaching to adaptive management.

Work in the Guadiana basin has focused on five main fronts:
  1. The first refers to stakeholder engagement and involvement, which has been carried out mostly via a series of thematic stakeholder meetings. Key basin stakeholders such as the Guadiana Water Authority, Spain and Portugal's Ministries for the Environment, the Agriculture Department of Castilla-La Mancha regional government, water user associations, farmer unions and environmental conservation groups have all shown an ongoing commitment to these meetings. A second participatory process was held using Bayesian networks (see Bayesian networks information below).
  2. A great work has been made also towards training and dissemination of NeWater knowledge.
  3. The third is more related to hard-science approaches, and focuses on the development of adaptive management tools requested by stakeholders. These include a specific hydrological model to test potential outcomes of EU and national agricultural and water policy. Furthermore, an agro-economic-hydrological integrated modelling framework has also been developed, with the aim of analyzing policy scenarios, including agricultural policies and water policies, and their socio-economic impacts on farms, considering the environmental, social and economic vulnerability of main actors involved in water use. In addition, the Guadiana team is coordinating research integration within the case study, while also contributing to the work of other NeWater WPs.
  4. The fourth relates to the use of Bayesian networks for developing a participatory process. Bayesian networks were used to test different management options and assess their consequences as the trade-off between agricultural economy and the environmental sustainability in the area.
  5. The fifth deals with the estimation of the Water Footprint of the whole Guadiana basin. This engages Luso-Spanish institutions facilitating the transboundary cooperation between riparian states. Considering the difficulties to work in transboundary issues, we contacted the National Water Institute of Portugal (INAG) to do jointly the Water Footprint of the entire Guadiana bains (see INAG letter). Some preliminary reports are available here.
