Cost-benefit analyses conducted for numerous rivers have demonstrated that rehabilitated rivers and adjacent parks contribute to the economic growth of localities by attracting private investment and increasing real estate values (MoEP, 2010). As of 2010, the allocation of water provisions to nature has been raised to 60 million m3 per year, including 10 million m3 of potable water and 50 million m3 of treated effluent. This allocation is targeted to increase to 95 million m3 per year by 2020. In 2003, the NPA assessed the water requirements of nature and the landscape in Israel.
