Figure 3. 15-year action plan scenario with changing cropping pattern and artificial
recharge system - groundwater levels simulation. Scenario 1: changing cropping
pattern - 6% decrease of the rice cultivated area every two years and at the same
time 20% increase of vegetable and flower cultivated area. Scenario 2: scenario
1 + additional artificial recharge structures (+ 2 mm/year) (tanks, dug-wells, etc.).
Scenario 3: artificial recharge only (dashed line) - 200 hectares of additional
water tanks (efficiency of one hectare of tank: 0.1% of R).
adding some rain harvesting structures (scenario 2) now significantly
maintained the water levels above. Drying up of bore-wells are also presented
(Fig. 4); all scenarios clearly improve the current situation.

recharge system - example of socio-economic impacts: drying-up of bore-wells.
Results from the scenario 1, 2 and 3. The vertical bars depict the degree of
uncertainty, which depends on the spatial variability of the aquifer thickness
(about 25% of uncertainty).
