In order to solve the problems of accessing to fresh food and water in communities in a sustainable way my approach for the solution can be described into three phases.
Phase 01 (the study phase) : the phase evolves with the root study of how the country as well as places used to be in past and how the problems were being solved at that particular time.
Phase 02 (connecting the dots) : This phase is basically focus on the solutions that has been used to solve problems and the evaluation of those processes.
Phase 03 ( Towards connected future taking the past) : This phase focuses on the development of problem solving approaches which is taking the past solution and develop it with technology and with context to solve the current urban problems.
Therefore, My solution for solving the problem of accessing fresh food and water in urban context ( after three phases of development) is to develop a design which will derive from traditional "macha'- framing concept with minimal surface and will act like a parasite in parochial urban grey spaces, roof top for producing food along with harvesting rain water.
Moreover, in my point of view, the approach will work towards urban sustainability since it pushes the parochial grey spaces to turn out to be green productive and connecting spaces to address a particular problem. Further research and solution approaches based on the idea will come up with great solutions for the betterment of world of urban sustainability.
