Water and sanitation services in the major part of Bethlehem District are under the responsibility of an intermunicipal operator, the Water Supply and Sewerage Authority (WSSA), which serves some 100,000 inhabitants.
Water-wise,Yemenis most commonly identified with scarce resources and arid landscapes. Less known are its longstanding users-led water management systems. The ingenuity and efficiency of these systems was such that they the country could meet its food/ water needs for about 1000 years, despite its climate and geography. TheWaterChannel created a video series called ‘Building on Practice,’ documenting case studies in local water management from Yemen.
KNOSSOS, KNOwledge from Science to SOcietieS, is a project, funded by the European Commission, which addresses the gap between science and society in the field of environmental research with a focus on policy makers. The initial phase of the project has been to take stock of the available environmental research results that are useful for policy makers. This information is added to the web platform, a knowledge management system which guarantees fast and easy access to relevant information.
The implementation of the dual water distribution network solved and addressed one of the most crucial issues of supplying suitable potable water to the city of Qom, encountered by the national and provincial authorities, as the quality of available potable water sources in Qom province had lowered due to inadequate rainfall in the previous years.
It enabled a production capacity of 1500 cubic meters per day, with the possibility of capacity increase to 4000 cubic meters per day
Deep Words, Shallow Words: An Initial Analysis of Water Discourse in Four Decades of UN Declarations
UNU-INWEH undertook an examination of the changing language of water in high-level declarations from eleven UN conferences on water and the environment over the past forty years. Both deepening and shallowing of key terms were evident throughout the documents and the report suggests effective strategies for highlighting and strengthening key concepts.
The Arab Water Forum, a platform for addressing regional priorities, identifying solutions and commitments
The solution developed consensus that Food security is essential for political, social and economic stability in the Arab countries and is strongly linked to water security. Agriculture will continue to be a major component of the regional economy, providing jobs as well as food security.
We want to describe and introduce some traditional methods for growing crops with minimum irrigation and even with no irrigation, once practiced in the Iranian desert. We have classified these methods into three categories as follows: 1- thorn-based cultivation: in this method such crops as cucumber or watermelon can live off the moisture being secreted out from the vascular system of some desert plants. 2- pottery irrigation: in this method the crop can be irrigated just by the minimal water seeping through a clay membrane into the soil according to osmotic pressure. 3- flood irrigation: the flash floods can be controlled and harvested behind the earthen dams in order to increase the soil moisture. Some crops can be grown behind the dams after the water would percolate the earth.
Guilspare is anorganic autodegradable polymer in a liquid form that farmers mix at 1 to 2% concentration to first irrigation water. Once in contact with air,Guilspare coats the particles of the soil on a few centimeters depth. The virtual film will prevent water from evaporation by capillarity, while gravitational water will keep on passing through.
Under its new Social Connection Policy, Nairobi Water Company allocates 1% of all water revenues to financing the extension of water services to the residents of the city’s informal settlements, who represent about 60% of the population. The funds are used for capacity development of the company’s informal settlements department, development of customer service systems for the low income segment, strengthening the contractual linkages between utility, small providers and consumers, mapping the existing assets, planning service improvements, project preparation, community mobilisation as well as infrastructure installation and refurbishment, where this is needed. The goal of the policy is to ensure there is a water service point within 50 meters of every household in the city.
The role of mountains in providing indispensible water resources for municipal and industrial water supply, irrigation, hydropower production, and other environmental services is well-known and unquestioned (e.g., Barnett et al. 2005; EEA 2009; Viviroli 2003, 2007).
Furthermore, several studies have also underlined the sensitivity and vulnerability of these mountain ecosystems to the impacts of climate change (Beniston 1994; Diaz et al. 1997; COM 2009).
