I guess the real question is, why does india want this land? I mean if it was all empty sand dunes, I assume there would be no problem. One answer seems to be water. Both India and Pakistan face issues with limited supply, and there is a treaty dealing with the rivers that supply Pakistan that it is worried India would break if water shortages became serious. You want a technological solution? Massive desalinization efforts on the Arabian Sea for Pakistan, and a system that piped water inland for storage against possible drought, as well as improvements in existing water utilization for agriculture and other uses, would probably render a lot of the tension over the area moot from the Pakistani side. Pakistan should invest funds to develop it's own system of desalinization plants, and expertise and research into water desalinization and water conservation, possibly by working with MEDRC in the Sultanate of Oman, which is centered in Muscat, about a 2 hour plane ride from Karachi. But I'm just spitballing, and this seems like one of those deeply complex issues driven by emotions that a purely technical solution won't work for.
