Problemas operativos en el manejo del agua en distritos De Riego | Operative problems in water management in irrigation districts

Mejia Saenz, E. | Palacios Velez, E. | Exebio Garcia, A. | Santos Hernandez, A.L.
In Mexico, water resources, apart from being limited, are badly distributed; on the coastal plain, with the exception of the Peninsula of Baja California and Sonora, there is an abundance of water, while in the rest of the country, it is scarce. With the transfer of the large irrigation districts to user organizations, it was intended that these districts become operationally and economically efficient organizations. In this way, decision-making passed from global planning, which covered an entire irrigation district, to fractioned planning, in which a small irrigation module is responsible for the administration of the water resource. Undoubtedly, the scarceness of this resource, together with the high demand of the agricultural sector and the low fees, is producing pressure for a change in the policies for management of this resource. In the management of the sources, it is not convenient to extract more water from the reservoirs than the average available volume; an additional volume generates less benefit, both economically and operationally, than what would be generated if it were stored for a dry year. In the case of the network, the deteriorated state of the infrastructure propitiates losses by leakage, infiltration in unlined ditches and inefficient water control in the channels. In the case of water management in the field delivery network, it is necessary to define actions to encourage the volumetric quotas and, in this aspect, the support of the government is essential; this means "political will," which could permit a considerable increase in the availability of water and, as a consequence, higher productivity of soil and water resources, as well as increased agricultural production and better incomes for the producers.

Afficher plus [+] Moins [-]Brazil : Managing Water Quality - Mainstreaming the Environment in the Water Sector | Brasil : a gestao da qualidade da agua - insercao de temas ambientais na agenda do setor hidrico Texte intégral

This study examines how environmental issues have been addressed in the water sector in Brazil, within the context of activities of the Federal Government, generally, and those implemented under Bank sector operations, in particular. The core focus of the study lies in the management of water quality, as it affects both the users of raw water, and those who are primarily concerned with the disposal of wastewater. The report considers the following three sectoral areas concomitantly - water resources management, water supply and sanitation, and, the environment - thus limiting its review, and focus to those themes which are key to the over-arching issue of water quality. Water resources management in the country relied upon heavy investments in medium, and large scale projects that provided basic infrastructure for water uses. However, these have produced questionable impacts in terms of reducing poverty, and inequality. One of the reasons for this, has been the poor infrastructure management, which despite its importance, has been largely underestimated. While improvements in the utilization of existing infrastructure in the water sector remain critical, it needs to be complemented by incentives to both service providers, and water users. Moreover, low economic, environmental, and social returns from investments in the water sector, reflect the tendency to distract attention from the objectives in the design, and implementation of projects. Thus, an assessment of water quality goals is required, which should be based on systematic evaluations of the costs, and benefits of reaching alternative standards, and explicit social objectives.
