Drought and decreased soil fertility are the classic problems in dry land agriculture. Farmers adapt these conditions in the form of soil and water conservation practices. This study aimed to find out 1) Tradition of soil and water conservation based on farmer knowledge as an adaptation to climate condition, and 2) Prospective technology for adaptation and mitigation of climate change in dry land. The research was conducted in the dry land of the karst area on Girisubo Gunungkidul D.I. Yogyakarta Indonesia, from September to November 2019, during the dry season. The research used the method of observation and farmer interviews. The results showed that tradition of conservation practices were carried out by farmers based on knowledge and information, with motive of economics and survival. Conservation practices as a form of adaptation, based on the management and potency of water, soil, and biomass resources. Water management includes making simple dam, making well, harvesting groundwater, and applying cropping pattern. Soil management includes making terrace, planting grass on terrace, and applying organic fertilizer. Conservation practice is one of the adaptive actions, with mitigation of climate change as a co-benefit. Practices that have the potential for adaptation with co-benefit mitigation are water and soil management, variety selection, direct seed planting, and composting. Farmers, as the main factor in tradition of conservation practices, determine the sustainability of agricultural system. SWC practices have potential to develop into adaptation co-benefit mitigation to climate change.

“…Secara khusus, Hornbeck dan Keskin (2015) menyebutkan bahwa pengelolaan air harus menguntungkan secara ekonomi. Pengelolaan air untuk irigasi tanaman menguntungkan lingkungan dari sisi peningkatan serapan karbon dari udara (Anshori et al, 2021c;Viandari dan Anshori, 2021). Pemanfaatan air tanah untuk irigasi lahan kering di musim kemarau terkait erat dengan aspek ekonomi, sosial dan lingkungan.…”

The provision of water for plants is a major component supporting the success of planting on dry land. One source of water that can be utilized is groundwater. This study aims to determine the use of groundwater in supporting the cultivation of groundnut, corn and soybeans on dry land during dry season. The study used plots of farmers' land to grow groundnut, corn and soybeans complete with technology packages for each commodity. The application of technology includes cultivating groundnut by farmers and cultivating groundnut, corn and soybeans according to the recommended technology components. Harvest data were analyzed descriptively. Economic analysis is used to calculate the profitability and feasibility of farming. The results showed that corn plants with technology recommendations gave the highest yield, dry seeds of 5.50 tons ha-1, dry biomass of 18.63 tons ha-1, with carbon absorption in seeds of 2.62 tons ha-1 and biomass of 8.92 tons ha-1. The profit from corn cultivation was 22,090,000 IDR ha-1 with a benefit-cost (B/C) of 1.35, groundnut 20,985,000 IDR, with a higher B/C of 1.50. Soybean plants provide the lowest profit and B/C, amounting to 4,124,000 IDR and 0.26. Technologically and economically, the cultivation of groundnut, corn and soybeans with the support of groundwater irrigation is feasible to develop on dry land during the dry season. Socially, groundnut is more accepted by farmers.

“…Lack of water will reduce crop production (Adunya and Benti, 2020). Water shortages can be met by irrigation from rainwater harvesting (Anshori et al, 2021a) or groundwater sources (Anshori et al, 2021b). Dryland has excellent potential for development (Indrawan et al, 2020) and proper management will support agricultural progress (Viandari et al, 2022).…”

Soybean is a highly nutritious and strategic food. The harvested area and production of soybeans tend to decrease, not sufficient for national needs, which must be met through imports. Breakthroughs are needed to develop soybean, with specific strategies to adapt to particular conditions, including in Gunungkidul Regency. This study aimed to reveal the soybean development strategies in the dryland agroecosystem in Gunungkidul Regency. Survey and interview methods were used in this research, supported by secondary data analysis and data from the previous year's research. The correlation analysis was used to determine the decrease in harvested area. Other data were analyzed descriptively. The results showed a significant decline in soybean harvested area between 2009 to 2020. The soybean development strategy is area-based, from upstream to downstream, involving both main soybean products and by-products. Soybean planting was carried out in the first, second and third growing seasons, using site-specific soybean cultivation technology, providing seeds through the Jabalsim System supported by irrigation. Policies are needed within the organization's scope, rules, guidance and protection. The final results of this research are embodied in the form of an area-based soybean development diagram in Gunungkidul Regency, which can be used as a development reference.
