- 1. Agriculture and GIS By:D.M.M Shanake H.W.W. Karunarathna H.M Samarapperume
- 2. Introduction • GIS hassuch valuable approaches in agricultural science and there is massive potential for such areas as agricultural planning, attractive implications for the future of managing of crop production and increasing yields in line with other technology. • Agricultural People are always looking at ways to best produce the crops, manage soils while Preserving the environment and protect them from disease and pests. There is an ongoing challenge to cope with the changing climate and needs of today. GIS can play a vital part in tackling these challenges.
- 3. Challenges to theAgriculture • Management of agricultural land • Soil analysis • Soil management • Examination of crop yields • Population growth • Climate changes • CO2 levels
- 4. Usefulness of GISin Agriculture • Use of GIS is fairly limited at present in Agricultural Development • But there are many acknowledged uses even where the tool is not actually being used in practice. • There are many strategic advantages and the industry is only just starting to notice them. • Avoiding droughts, floods and insects, by strategic planning can improve both yield and quality of a crop and changing crops as soil changes can maintain maximum yield and protect the environment.
- 5. Usefulness of GISin Agriculture • For the most of the time agricultural planning has been a system of guesswork or Depend on Prediction. • GIS can take the guesswork out of the crop planning management with effective collection of soil data and seasonality of topography in line with changing conditions. It allows for precision farming and maximize the yield and its quality. • How much sunlight, shade or rain a certain area gets. • The nearness to a road or Industrial Area (potential pollution level, dust or fragments of artificial material such as rubber and metal).
- 6. Usefulness of GISin Agriculture • It will be useful as its Already implemented in Archeological Science, for agricultural science as underlying features and underlying bedrock can affect the quality of the crop produced. • Identifying new areas to plant crops, either to make existing yields more efficient or simply to continue to provide increasing yields for our growing global population, is presently and will continue to be the biggest challenge for agricultural science. • GIS is presently being used to manage food security and to reorganize crops in the third world to ensure that maximum use is made from the fragile soils in some areas.
- 7. Usefulness of GISin Agriculture • GIS is essential in mapping areas, especially food sources, that are vulnerable to natural disasters such as drought and flood. • The World Food Program, the division of the United Nations concerned with food security, is one of the biggest users of GIS data for this purpose . • They are involved in protecting food supplies by effectively building simple civil engineering projects such as damns, levies and irrigation to protect food supplies • GIS is an essential tool in land planning anywhere in the world, to strike the balance between the social demand of the land and its environmental potential capability.
- 8. Summary • Greater analyticalsupport for precision farming • Better understanding of risk factors • Higher revenue generation and cost recovery • Greater efficiency through task automation • Greater access to government services and data • More accurate support for decision making • Greater insight to policy making • Easier reporting for government applications and regulatory compliance • Better resource management
