About the Practice
Problem Statement:

While unavailability of human labour for usual farm work like weed removing, harvesting etc. itself poses a major problem today little can be said about removing the stones from the fields. Generally it is the women who remove the small stones and pebbles before the start of the cropping season. While there are several machines for sowing, spraying and harvesting till date, no machinery has been developed for this purpose but important aspect in farming. It was left to Shri. Ranabhai Khunti and his brother, Shri. Rajubhai Khunti, a innovative progressive farmer from Ranavav, Porbandar, to develop a tractor operated stone picking machine.


Shri. Ranabhai and his brother developed a machine which can able to collect stones from the farm field. This machine is tractor operated and collect the stone from the 5 to 6 inch. They spent around 11 years of his life in optimizing various mechanisms to perform this function (stone picking and collecting) optimally. Able to collect stone per Acre (2.5 Bigha) in only 3 hours.

Practice Details

Link: "A transboundary multi-stakeholder institutional mechanism that is scalable (RURBAN) RURBAN Platform is a mechanism developed to create a participatory approach to water management that cuts across urban-rural silos and builds capacities among key local stakeholders to design and implement climate-adaptive water management as a collective group, through a menu of intervention options, including: better integration of water supply protection, urban water services, stormwater management, wastewater reuse, and promotion of conjunctive management of surface water and groundwater. The framework for the interventions is to organize around the geographic boundaries of the watershed and support the design of policies and programs that can integrate both upstream and downstream interventions, spanning the water cycle from source, to use, to treatment and reuse to ultimate disposal. Simple and intuitive data analysis and visualization tools We have customized an open source software (Water Evaluation and Planning System (WEAP)) to provide a simple water balance model that can be updated and visualized in real time. Using a scenario analysis tool as a boundary object, it enables active stakeholder engagement, facilitating shared learning and discussion. Use of our modeling tools is crucial for this process, because scenarios can then be negotiated based on stakeholder inputs, in real time. We made the RURBAN modeling tool to be as flexible as possible, with dynamic outputs, while remaining simple and easy to understand, so that they can be used to analyze management scenarios while also simultaneously soliciting community perspectives. This allows the decision-making process to be transparent, rapid and iterative. In our piloting of the tool, we found that through this deliberation, the group eventually adopted solution pathways based on the decision support tool outputs"
