I agree with Amrita's points above and would just like to add that it would be good to quantify the number of households (including women, but also elderly and children) that would economically benefit from pond restoration..

In response to this, is the crucial hydrological purpose of ponds in storing excess runoff and recharging groundwater. I have been investigating the disappearance of urban ponds in Hyderbad (India) as part of my PhD research.. This has worsened the floods in the city during and extreme rainfall events. So I'd be confident to say that the restoration of these ponds serve an important purpose of reducing to some extend the costs associated to flood damage.
