Abstract: Desertification has made productive landscapes in South-western Thar desert redundant and subjected people to migration. The high wind velocity and substantial lack of vegetation cover have subjected the region to an ‘Extremely’ high wind erosion index (Ashok & Amal, 2004) and an unstable dunal terrain. While the strong wind patterns drive the dynamics of sand, harnessing the energy using indigenous and modern mitigation techniques can allow resilience for productive landscapes to flourish and settlements to co-exist. The paper sets out a theoretical framework for this system of co-existence by focusing on a synthesis of technologies to alter the velocity of sand laden winds at different scales and timelines. The paper proposes application of these techniques in parallel and in sequence at multi-ple timeframes to develop in-dune habitable spaces. These sand laden winds are reduced in velocity to support the initial phase of terrain stability, deflected by in-digenous trees and a roofing mechanism designed to ensure sand-free habitable spaces and lastly, accelerated through a series of sand channels to be taken out of the system in a controlled way. A series of computational simulations including CFD, and multi-objective optimization are utilized to develop a feedback mecha-nism between the architectural constraints, namely of the roof and sand channels, and the resulting aerodynamics of wind to ensure an effective deflection and accel-eration. The potential of scaling up the system and controlling the aeolian processes at a regional scale is critically analyzed.
