A Study on Land Suitability for Rice Cultivation in Khordha District of Odisha (India) Using Remote Sensing and GIS

Abstract

With the global population on the rise, it is important to address the increasing demand for food. According to FAO (Food and Agriculture Organization, United Nations), by 2050, the developing countries must double their food production to meet the growing demand. Proper land utilization can be one of the solutions for this problem. In view of this, the current study focussed on land suitability analysis for Khordha district of Odisha (India) for rice crop. This study estimated that the amount of land suitable for rice cropping was 195,731 ha against the currently cultivated land of 122,183.38 ha. Therefore, there was a possibility of more amount of land that could be available for rice cultivation in Khordha district than the currently cultivated area. In order to perform this exercise, the land use and land cover data from IRS (Indian remote sensing satellite), soil nutrient parameters like pH values and nitrogen, potassium, phosphorous and organic carbon contents were considered. In addition, the climatic parameters such as near surface temperature, rainfall and number of rainy days were taken into account. The unused land identified in Khordha district in this study might be utilized for cultivating rice crop in this region.

Land Suitability Modeling For Ricecrop Based On An Integrated Multi-Criteria Decision Making In Quang Tri Province Of Vietnam

“…In Vietnam, the irrigation system remains underdeveloped and has not been modernised, the state of the irrigation system has an effect on rice production in the province. Some other studies on the evaluation of suitable potential areas for agricultural activities in the semi-arid terrestrial ecosystem in the Central Anatolia Region, terrain properties and soil features also were used to identify sites suitable for agriculture lands, the authors used both physical and chemical factors of soil to evaluate soil nutrition and soil quality index (Sezer et et al 2020, Seyedmohammadi 2019, Rath et al 2018. The information was gathered through a variety of methods, including literature reviews, a structure-questionnaire, focus group discussions with local stakeholders, and individual interviews, all of which were conducted using the techniques of Participatory Rapid Appraisal and conceptual content analysis to gather the information.…”

“…The information was gathered through a variety of methods, including literature reviews, a structure-questionnaire, focus group discussions with local stakeholders, and individual interviews, all of which were conducted using the techniques of Participatory Rapid Appraisal and conceptual content analysis to gather the information. As a consequence, the diagnostic criteria for sustainable land management were developed in accordance with the framework for assessing sustainable land management, and they are as follows: productivity, security, protection, viability, and acceptability (Rath et al 2018). It is possible to apply and assess the sustainability indicators identified in these study in rice crop production regions of our study, which might result in the development of a strategic plan and increased sustainability in the future.…”
