GIS for Agricultural Planning at Village Level

Agricultural activity is best handled through community participation. This is particularly relevant in the case of Goa, India where farm holdings are extremely small and fragmented. In community farming, resources are shared and managed together, thereby bringing greater benefits to all. Geographic Information Systems (GIS) can be used to map and quantify all the available agricultural land in a village and identify its status of utilization, i.e. whether it is cultivated or not.  

An Agricultural Map of Carmona Village in South Goa is shown here. In order to map all the designated agricultural land in the villager, the Regional Plan for Carmona was used as a basemap. Various high-resolution satellite imagery was interpreted using Google Earth Engine and Google earth pro to identify cultivated and uncultivated areas. The map was further validated on the ground with farmer inputs before it was finalized.

Using this map, the village can better plan logistics for cultivating 250.5 ha of agricultural land, of which 90.2 ha are cultivated and 160.3 ha are uncultivated. 

On the basis of the spatial insight provided by the map, the farmers have identified four clusters of areas. Clusters have a designated farmer in charge to oversee all the farmers who have land in that particular cluster. This is the first time a local farmers' group has used GIS and Remote Sensing technology for grassroots planning in Goa. There is still a long way to go, and more plans for GIS implementation are in the works. This will be covered in another post. watch this space. Thanks for reading.
