“…The production of food crops based on plant type is an indicator of success or the achievement of the agricultural sector. Furthermore, the high or low production or productivity of food crops demonstrates the level of commitment of the government and farming communities to achieve food independence [10]. The food in question can be sourced from rice as the primary food ingredient, and other alternative foodstuffs such as corn, yams, and soybeans.…”

The development of land use activities in the Tinondo Swamp promotes the acceleration of spatial planning to ensure sustainability. This research aimed to evaluate land use in Tinondo Swamp and to provide alternative areas in the spatial plan of the east Kolaka regency. Primary and secondary data were collected using survey methods. The research used qualitative and quantitative methods to analyze the deepening and scanning of autopilot aircraft, the environmental carrying capacity, linkages and existence of linkages with the community, the needs of facilities and infrastructure, and spatial analysis. The results showed that the survey area of the Tinondo Swamp was 5,699.41 hectares, consisting of 11 land-use types. There are swamps with an area of 1,999.34 hectares (35.08%), settlements of 133.41 hectares (2.34%), the company’s Base Camp of 0.94 acres, the forest of 104.65 hectares (1.84%), swamp forests of 178.02 hectares (3.12%), roads of 26.22 hectares (0.46%), canals of 51.59 hectares (0.91%), mixed gardens of 489.88 hectares (8.60%), oil palm plantations of 1,178,298 hectares (20.67%), rice fields of 1,536,096 hectares (26.95%), and open land of 0.96 hectares. Furthermore, the total survey area that is available and planned for was 1,999.34 hectares.

“…The Soil and Water Assessment Tool (SWAT) is a widely used hydrological model that uses a geographic information system (GIS) interface to capture landscape variability and runs on a daily time step. SWAT has been used to simulate water resource assessment (Krysanova & White, 2015; Gupta et al, 2020); map agriculture water productivity (Garg et al, 2012b; Thokal et al, 2015; Ahmadzadeh et al, 2016); optimize reservoir operation (Wu & Chen, 2012; Anand et al, 2018); study the impact of land use and management practices (Krysanova & White, 2015; Jodar‐Abellan et al, 2019); study climate change effects (Narsimlu et al, 2013; Uniyalet al, 2015; Marin et al, 2020); and quantify various ecosystem services (Dile et al, 2016a, 2016b; Lee et al, 2018). It has also been used to analyse upstream–downstream water balance at meso‐ (Dile et al, 2016a, 2016b), catchment and basin scales (Masih et al, 2011).…”

The Cauvery basin in southern India is experiencing transboundary issues due to increasing water demand. This study analysed water balance components and the impact of agricultural water management (AWM) interventions in the upper Cauvery catchment of the Cauvery basin. Results showed that the study catchment receives an average of 1280 mm of annual rainfall.Of this, 29% (370 mm) flows downstream, 54% (700 mm) contributes to evapotranspiration (ET) and 17% (215 mm) contributes to groundwater recharge and surface storage. Rainfall varies from 700 to 5400 mm and the Western Ghats (mountain pass) are the main source of freshwater generation. The estimated ET in different catchments ranged from 500 to 900 mm per annum. An increase in the allocation of fresh water supplied by all three reservoirs (Hemavathi, Harangi and KRS) was observed in the canal command areas, from 1450 million cubic metres (MCM) yr‾¹ in 1971-1980 to 3800 MCM yr‾¹ in 2001-2010. AWM interventions harvested 140-160 MCM (13-20 mm) of surface runoff upstream of the upper Cauvery and reduced inflow into the Krishnaraja Sagar reservoir by 2-6%. The study findings are useful for designing and planning suitable water management interventions at basin scale.
