  • Funding for forests: the potential of public ballot measures

    A variety of measures exist to prevent deforestation or forest conversion to other land uses. Some of these measures, such as purchasing land outright for conservation or purchasing conservation easements, are designed to permanently protect forests by precluding future residential or commercial development on the tract of land. But these approaches all require money. One approach to raising ...

  • Potential water savings associated with agricultural water efficiency improvements: a case study of California, USA

    This study analyzes the potential for water savings from irrigation efficiency improvements in California, USA. We model water savings associated with three efficiency scenarios in wet, average and dry water years. The ‘efficient irrigation technology’ scenario shifts a fraction of the crops from flood irrigation to sprinkler and drip systems; the ‘improved irrigation scheduling’ scenario uses ...

  • Use of sea water and hydraulic conditions. Potential cause of Mortality by Metals and Hydrogen Sulfide in Recirculation Fisheries

    The traditional conception in Chile of the toxic effect of metals on cultured fish tends to weigh heavily on incoming freshwater in open flow fish farms as the major responsible for mortality in early stages of development in salmon species. This approach is mainly based on two conditions that refer to freshwater quality in Chile, and to the dilutive effect of recirculation fish stocks when a ...

  • Assessing potential of water rights and energy pricing in making groundwater use for irrigation sustainable in India

    Groundwater emerged as a major source of irrigation in India during the mid-1970s. However, a large expansion in well irrigation due to a massive rural electrification programme, government policies of promoting private tube well construction and large subsidies on electricity for agricultural use resulted in groundwater over-abstraction in many semi-arid and arid regions of India. In addition, ...

  • A distributed hydrological model in the Heihe River basin and its potential for estimating the required irrigation water

    A Grid-based Integrated Surface–Groundwater Model (GISMOD) was developed to estimate the required irrigation water using a control-site method. The entire catchment is divided into multiple grid cells of equal size, and several grid cells can be chosen as the control sites by users in this model. The grid cells from the upper stream of each control site, which have a land-use type of farmland, ...

  • Potential drawbacks associated with agricultural irrigation with treated wastewaters from desalinated water origin and possible remedies

    Over 90% of the water supplied in the coastal region in Israel in 2013 (600 Mm3 y−1) will be from desalination plants. The wastewater generated from this water (>400 Mm3 y−1) is planned, after proper treatment, to be reused for agricultural irrigation, making this low-salinity water the main agricultural-sector future water source. In this respect both the Mg2 +  concentration and the Sodium ...
