Strategies 

The strategies are developed to solve the problems in the future (mentioned in problem description). The results for the strategies are obtained and then by changing the parameters and the structure of the model as per the strategy the results are compared with the existing situation and with which we can implement the best strategy to improve the conditions in future. We have selected the strategies in such a way that it would help us to study the behaviour of each variable mentioned above i.e. we have strategies for water, population, land and quality of water and finally we can know about the behavior of the system. We have selected more strategies to cope up with the ground water as it is the main problem in the Azag strip but we also have other strategies for different parameters, as the system is dynamic. The strategies adopted are:

Strategy 1
Adopting Rainwater harvesting techniques. This would help us to decrease the domestic water supply. So we subtracted the area of household from the total land as precipitation is considered for the total land and changed the consumption per capita.
Assumption: Affects 50% of total domestic water supply.

Strategy 2
Use the drip irrigation, which would help to reduce the agriculture water demand, hence we changed the water demand per donum.
Assumption: Decrease by 50% in the water demand and its efficiency factor of 95%

Strategy 3
Recycling of the used water form different sectors would affect the total water supply and would also reduce the seepage of nitrate form the cesspits, so we changed the total water supply and also the seepage from the cesspits. This would affect the pumped water also.
Assumptions:  Decrease by 50% of the total water supply and seepage from cesspits would decrease by 70%.


 

Strategy 4
As Azag strip is located on Mediterranean coast and water from the sea can be desalinated and used. This would affect the pumped water from the ground. So we changed the percentage of the abroad water and also the condition of the pumped water from 90% to 60%.
Assumptions: We changed the abroad water from 10% to 40%


Strategy 5
This strategy is basically for affecting the increase in population. This can be done by some policies and awareness programs, which would affect the population. To do this we changed the birth rate.
Assumption: The decrease in birth rate from 0.6 to 0.45 from 2003 to 2025.

Strategy 6
Developing a technology that would affect the concentration of the nitrate seepage from the cesspits. This would affect the quality of the water.
Assumptions:  Changing the concentration of nitrate from cesspits from350 mg/l to 250 mg/l and this strategy is based on the idea that after 10 years the sewerage system  would be developed and there wouldn’t be seepage after 20 years.

Strategy 7
By distribution of agricultural land i.e concentrating more on non irrigated sector as the water required is less, which would affect the water supply for agriculture as in future if the water isn’t available the irrigated land would be converted to non irrigated land.
Assumptions: growth of irrigation area from 3% to 1% and vice versa for non irrigated area.
