One friend told me her daughter bought her 12 x 24 foot tarp in Jammu last year for Rs. 1,800 (about $30). With all our weather changes - from the hottest August ever where tarps were used for shade, to the endless rains last month where a tarp made the difference in saving this year's crop - tarps sell for twice that in-District if you can find them.
That's why we are so lucky to get UV resistant polythene for our flood relief recipients from the Department of Agriculture. Costing less per square foot than anything else available too. In spring, it can be used to start bedding plants.
And if the rains come next year, in autumn it can be used to save the harvest or the house.
