การบริหารจัดการน้ำที่มีผลต่อทรัพยากรธรรมชาติและสิ่งแวดล้อมแบบบูรณาการ : กรณีศึกษาโครงการพัฒนาลุ่มน้ำลำพะยัง (ตอนบน) อันเนื่องมาจากพระราชดำริ อำเภอเขาวง จังหวัดกาฬสินธุ์ / วัชรินทร์ เจตนานนท์ = Integrated water management for natural resources and environment : case study The Royal-Intiated Lamphayang River Basin (upper part) Development Project Khao Wong district, Kalasin province
This study is in-depth analysis of water management in the way of new theory by using the principle of land resources, water resources and population management concept (LWPM Concept) for applying in the area of the Royal-initiated Lamphayang River Basin (upper part) Development Project, Khao Wong District, Kalasin Province. The objectives were to study water management including water utilization in the past, present and expected water use in the future and recommend appropriate guidance for the area. The results show that: (1) Land resources; soil is sandy loam, has low fertility and needs to improve suitably for agricultural land (2) Water resources; water quality in the Lamphayang reservoir is still suitable for agricultural practices which the highest volume of water storage is 4,000,000 cubic meters. During the year 2002-2008, the average volume of water storage is 3,030,831 cubic meters. The water requirement in the area for planting season of 4,600 rais was 3,889,844 cubic meters. The dry season of 376 rais, crop water requirement was 637,642 cubic meters. The study result showed that volume of water does not enough for agricultural practices, especially during the dry season. (3) Population; the estimates of future population will be increased but are not affected the uses of agricultural land in the near future. The study has found that major problem in the area was inadequate water for agricultural practices. The new theory according to His Majesty the King was applied to every agricultural plot. The results showed that the new theory can solved most of the problems within the study area. This measure can be recommended to apply to similar situation in the other agriculture lands.
