Water
resources are subject to severe degradation due to many factors as consequences
of global climate change, rapid population growth, changes in land-use,
agricultural and urban expansion, increase in the demand for water by various
sectors, inadequate distribution of water resources, deterioration of water
quality due to overexploitation, and rainwater scarcity. As such, searching for
alternative water resources (AWR) has been a key issue of today. These are
namely; treated urban wastewater, harvested rainwater and desalinized seawater.
This chapter is devoted to details of these 3 alternatives, and technical
information as well as the recent situation of prominent countries utilizing
AWR in irrigation practices are introduced. This topic is of high interest as
the major water-consuming sector is agriculture. As seen from the case studies
underlined in this chapter, RWH seems to be an appealing option over freshwater
resources especially in arid and semi-arid regions of the world facing water
limitation. Beyond the main advantages of regaining water for especially irrigation
purposes also bear some disadvantages like public health concerns and risks. If
appropriate treatment lacks, AWR may cause accumulation of various pollutants
and pathogens on crops that may further enter the food chain. Therefore, food safety
implications and policy development in coping with this risk may be realized
through applying strict regulations at country levels. Both the farmers and the
public need more training on the safe use of AWR even though the public
awareness tends to increase. The last part of this chapter is spared for food
security implications and studies of some countries coupled with social
acceptance concerns.
