The land nobody wanted
Vallandai in 2007 was not farmland. It was scrub.
For decades the land here had been given over to prosopis juliflora, the thorny bush locally called semaikaruvel or kaattu karuvelam. Local people grew it, burned it, and sold the ash. It was a living, but it came at a cost nobody had calculated. The bush drew groundwater relentlessly. Season after season the water table fell, until the soil could no longer support a crop at all.
The farmers gave up. Land that should have been productive sold for ten to fifteen thousand rupees an acre, and even at that price there were no buyers. Ramanathapuram became one of the driest districts in southern Tamil Nadu.
