Internet based Dairy Geographical Information System (i-DGIS)

 

1. Introduction

Co-operative Milk Unions in India are farmers’ organisations, which operate in large geographical areas with multiple activities to support the dairy farmers in villages. For proper monitoring and planning of these activities, it is thus important that the villages are properly identified on a digital map and also all relevant village level data are integrated and presented together under one platform. With the advancement of internet based GIS technology, it is now possible to integrate and quickly disseminate the tremendous amount of attribute and graphical data of villages into usable information for decision making by all stakeholders of the dairy sector. This article focuses on the development and implementation of Internet based Dairy Geographical Information System (i-DGIS), a strong visualization tool, which not only enables identification of villages but also integrates human census and livestock census of villages, in all the major milk producing states of India. It has been developed by the National Dairy Development Board (NDDB), primarily to support the End Implementing Agencies (EIAs) of the National Dairy Plan-I, who are mostly Milk Unions. Further, it can also act as a tool for convergence of planning of activities related to the dairy sector, for multiple stakeholders like Animal Husbandry Dept of State / Central Govt, Livestock Development Boards, NGOs etc.

Milk production is dependent upon many environmental as well as socio-economic factors and varies significantly across many parts of the same district or even same sub-district (tehsil). Thus, dairy development activities in the rural areas needs to be planned in such a way that it takes into account the local socio-demographic factors and the dairy potential of that area. With the advancement in GIS & RS technology coupled with smartphone/GPS technology, immense possibilities have been opened up for developing web GIS tools, which can address the problems of monitoring and planning of village level activities pertaining to the dairy sector. Internet based Dairy Geographical Information System (i-DGIS) had been conceptualized to take advantage of these technologies in proper identification of villages as per the Census of India village codes and also provide an internet platform for rapid dissemination of village level integrated information pertaining to the dairy sector.

2. Framework of Internet based Dairy Geographical Information System (i-DGIS)

i-DGIS has been developed as a strong GIS visualization tool, proposed for making it available on the internet platform by NDDB, primarily for the benefit of EIAs under NDP-I, for their monitoring & planning activities under the aforesaid plan. Further, it is also proposed for use by various Technical Groups of NDDB, State/District level Cooperative Milk Unions/ Federations, Dept. of Animal Husbandry & Livestock Development Boards of State Govts.

EIAs operate in large geographical areas with multiple activities, which is spread across many village locations. Knowing the locational boundaries of the village on a digital map, where any specific dairy development activity is already taking place or is proposed e.g. milk procurement, ration balancing, fodder development, artificial insemination etc would help in convergence planning among multiple stakeholders, as mentioned above.

i-DGIS is also designed so as to help in proper identification of these villages on digital map with village census code. It can be used as a readily available platform on the internet, for showing proposed and active villages in the milkshed area covered by EIAs. Process of identification of villages by the EIAs is explained through i-DGIS platform & GPS and/or Mobile/Smartphone Handsets (whenever required) in the workshops conducted by NDDB.

Most importantly, proposed use of i-DGIS is for monitoring & planning of field level activities of the EIAs under NDP-I, as human census and livestock census of the village is integrated and provided in one place on the digital map.

Integration of attribute data and graphical information in i-DGIS results in the ability to turn a tremendous amount of data into usable information. The resulting useable information of i-DGIS, facilitates decision making and spatial analysis through the use of visual display tools, in a way that would not be possible utilizing ordinary computer displays and printouts.

The web server has a repository of 580 digital district maps (as scanned from Census of India district handbook publications) with the aforesaid layers out of 640 districts in the country as per Census 2011. This has been created as a single geodatabase. Census 2011 standard coding pattern were used for identification of District, Sub-district (Tehsil) and Village. Scanning and digitization of all layers from the Primary Census Abstract (PCA) data handbook from Census of India, consisting of more than 5 lakhs villages and linking those polygons with standard codes of district, tehsil and block was the major work. Further, considerable effort was made for creating village wise derived layers (attribute data) from Human Census and Livestock Census, which had to be integrated and provided in the same platform.

Angular JS Front End, Node JS Backend and Mongo Database make up the technology stack for i-DGIS framework.

4. Utility of i-DGIS

The i-DGIS application is the first attempt of its kind, where village level integration of data has been done, at such a large scale, for the dairy sector. Many GIS analysis, both spatial & non-spatial can be made through this application. Some illustrative examples are given below,

#Kolhapur Milk Union in Maharashtra has initiated a “re-vegetation” activity of a fodder development programme in this village under NDP-I. As a stakeholder, information is required for promoting dairy related activities pertaining to this particular village. The i-DGIS provides the information as below along with map. (map1)

Village: Gogave,
Tehsil: Sahuwadi
District :Kolhapur (Maharashtra)
Households: 373 Buffaloes : 205 Xbred Cows: 117
Population: 1809 Cultivators: 616 Agricultural Labourers : 14
Village Area (in hectares):764 Cultivated Area: 715 Irrigated Area: 23 Culturable Wasteland: 11

It can be seen that along with the village boundaries (which are important to delineate the area within the village, where culturable wastelands are present for possible fodder development) , i-DGIS is able to show the entire datasets pertaining to village wise Human Census, Livestock   Census and Village amenities dataset.

#Which are the villages that lie within 2-3 Km on either side of this road? Can some of these villages with dairy potential become part of our program by extending the existing milk route?

6. Conclusion

The full potential of internet based GIS for development of the dairy sector can only be realized if all stakeholders to initiate a process of data integration at the village level by pooling different information on a common standard code viz. Census of India village codes. For example, diary infrastructures created by the Milk Unions/Federations at specific locations i.e. Bulk Milk Coolers, Chilling Plants, Dairy Co-op Societies etc at the village/town levels can be mapped; similarly village level fodder development activities under GOI sponsored Accelerated Fodder Development Programme (AFDP), Drought Proofing Activities under MGNREGA, fodder development activities under National Livestock Mission, Watershed Development etc can also be mapped and shared.

The IT technology is now geared with MIS, GIS & GPS technologies, in an integrated manner to provide us with user friendly platforms for monitoring of developmental schemes and plans. It can be seen that the plethora of information at the village level can be easily translated and understood in one map.
