GIS in Agricultural Survey
GIS is a geographical information system designed to capture, store, manipulate, analyze and manage all types of spatial or geographical data. It plays an important role in agricultural survey at local, regional and global levels. The use of this tool helps farmers with selection of agricultural products, seeds, fertilizers, pesticides and other chemical needs. GIS helps to maximize profits and optimize user`s needs in selection of right crops and equipment to the place where they should be implemented. Software allows to monitor the current condition of individual crops and adapt them to changes and differences like soil types, slopes, amount of precipitations.
Use of GIS in Agriculture
Agricultural is a known business based on cultivation of different types of products to sustain and enhance human life. Modern agronomy requires continuous analysis of the processes during the cultivation periods and technological development allows in many cases to monitor it. The agricultural mapping has been done to get information on following points:
- Agricultural status of crops.
- Analysis of an environment.
- Land mapping through irrigation.
- Soils analysis.
- Pest control.
- Determination of yield of the crops.
GIS allows to map individual variations in your field, analyze different factors that have an impact on crops and collect detailed information about your observations, forecasts and planning.
An increase in population has supplemented the agricultural production in more refined manner in the world. To boost the products in more advanced way, the quality and quantity of product play an important factor to obtain reliable data source. The main advantages of using GIS are:
- Agricultural mapping or survey using GIS is an effective technique to upgrade the farming system. GIS mapping implements the accurate information about the present geographical condition of agricultural resources.
- It is an essential tool to monitor and organize agricultural management system.
- The images captured through GIS show the variation in drainage and organic matters in agricultural system. Categorizing of maps is done to define the quality of soils. Also, this type of data helps to direct the agricultural resource at right manner.
- GIS helps to shield the crops, identify erosions, resolve crop issues, detect the damage and degradation, analyze soil and irrigation adaptation, and determine the crop health including variation in precipitation and temperature of crops.
- Agricultural mapping provides the details of vegetation study and monitor the crop models according to seasons.
Due to technology development, the country Nepal is using GIS to make development in agricultural field in the following ways:
- Nepal Agricultural Research Council (NARC) helps agricultural researchers to discover the agricultural issues mainly to farmers by using modern technology.
- The Soil Science Division set up the digitization, computing and analyzing the agricultural information with output results in the GIS Lab.
- In addition, GIS has increased the agricultural knowledge scientifically to the farmers. The Technique of GIS was applied to monitor and map different food crops (rice and wheat) and cash crops sugarcane) including horticulture. It improved the national economy.
- Similarly, GIS has ability to identify the suitable place for agricultural sites.
GIS plays a fundamental role not only in physical features of crops but also in determining the crops output and economic feasibility. The software upgraded the farming system in rural and urban area. Farmers have an access to estimation of crops accuracy data that can potentially increase crop yield. The modern technologies of recent agricultural activity have good management practice of agricultural productivity. GIS mapping not only has a remarkable field in physical environment but also in economic aspect to maintain sustainable environment.
Gis Network at Thakur International has international expertise for mapping, digitizing, modelling, project implementation in the field of Agriculture.
