Developing the potential of agricultural areas caused by climate change Ban Pla Bu, Nong Saeng Subdistrict, Wapi Pathum District Maha Sarakham province

Abstract

The objective of this research is to: 1) study the impact of climate change on water and soil salinity in agricultural areas, 2) develop risk maps for water and soil salinity in agricultural areas and propose a corresponding mobile application, and 3) enhance soil quality using biotechnological products derived from bacteria to support crop growth in areas with limited water resources. The research is conducted through a participatory action research approach, with the target community being the residents of Plabu Village, Group 14, Nong Saeng Sub-district, Waeng Pa Thum District, Maha Sarakham province. This small village, with approximately 250 residents in 80 households, relies on agriculture, including rice cultivation, animal husbandry, and vegetable gardening, covering an average of 22 acres per family. The project fi ndings include: 1) climate change impacts, such as 1.1) increased fl ood risks in the southern part of the village, and 1.2) drought risks affecting agricultural areas heavily dependent on natural water sources forz rice cultivation, 2) the development of risk maps for water and soil salinity revealed natural limitations in soil salinity and water quantity and quality. Local policies promoting shared water resource management are crucial for addressing these challenges, and 3) the creation of the “Water and Soil Salinity in Agricultural Area: WSSA” app, utilizing data from meteorological radar, rainfall, river water levels, soil salinity, and presenting risk maps through community forums. Furthermore, the research explored the use of biotechnological products from bacteria, specifi cally the collaboration with the Department of Land Development’s Super PD 2 formula, to improve soil quality. Initial feedback from collaborating farmers, Thanyarat Suriyakant and Siwakarn Khongsri, indicated satisfaction with reduced production costs and a shift towards organic farming. Crop yields from fi elds using biotechnological products were notably higher, with a 15% increase in rice production compared to non-treated fi elds. Despite positive outcomes, the target group still seeks continuous support from government or other agencies to address agricultural challenges arising from climate change, ensuring sustainable livelihoods and resilience in the face of environmental changes.
