English Abstract

Gaza Strip has an acute deficit in water both for domestic and agricultural use.

This deficit is related to water quantity and quality.

Agricultural sector is the main water consumer in the Gaza Strip with not less than 50% of the total groundwater extraction.

The main aim of this research is to planning of agricultural practices based on the updated water deficit in terms of quantity and quality, in addition to incorporate the non-conventional water resources such as treated wastewater as a new agricultural water supply.

The ArcMap ArcGIS was used to find out and update the agricultural land in Khanyounis governorate through new aerial satellite image of 2012 year.

Cropwat8.0 model was used to estimate the agricultural water consumption by utilizing the available information of land use, rainfall, and other meteorological data.

The Water Evaluation and Planning System (WEAP) was used to simulate water demand and supply under different four scenarios in Khanyounis governorate till the year 2030 as follows: 1.Business as usual (Zero scenario), 2.Using Treated wastewater (TWW), 3.Changing crop pattern, 4.Combination scenario two and three.

The results showed that the area of existing agricultural land are 61,200 dunum.

It was classified into four main categories: Orchards tress, Plastic green houses, Vegetables ,and Rain-fed crops.

The total annual crop water requirement is calculated to be 24.2 MCM.

The results of scenario 1 explained that the average water consumption for domestic and agricultural demands was doubled in reaching of year 2030.

In the second scenario it is found that it can save 7.90 MCM annually when start plant operations in the year 2030 and save 16.40 MCM annually in the 2nd stage from the of the operation of TWWP in the year 2025.

The results of the three options of scenario 3 explained the possibility of saving 1.35,6.06, and 8.76 MCM annually for the three option respectively.

Scenario 4 results showed that it can save fresh water from groundwater aquifer 16.40 MCM annually without any changing in crop pattern while in the first option it can save 10.85 and 17.75 in the years 2018, 2025 respectively, in the second option saving quantities are reach to 15.56 and 22.46 in the years 2018 ,2025 respectively , finally in the third option the saved quantities reach to 18.26 and 25.16 MCM annually in years 2018, 2025 respectively.

The study concluded that the fourth scenario using TWW and changing crop pattern will enhance reducing stress on conventional water resources which might improve the groundwater availability in Gaza Strip
