“…In general, rising temperatures cause an increase in WUE and iWUE, but this increase is not always related to increased crop productivity because it only gives plant breeders and physiologists an estimate of how e ciently the plant uses available water under the studied stress or high temperatures (Kilemo, 2022). In our study, almost all used germplasm showed an increase in the WUE and iWUE (Supplementary Table 1).…”

Heat stress is one of the major factors reducing potato yield by limiting the plant photosynthesis activity, production and partitioning of assimilates to the sink. Potato wild relatives (Solanum sect. Petota) are a natural reservoir of valuable traits for abiotic stress resistance. However, it is necessary to assess the response of wild potato genotypes based on physiological features such as gas exchange, chlorophyll index and chlorophyll fluorescence that are promising candidates to improve crop photosynthesis under adverse conditions. Multivariate approaches on two factor experimental design were used to select the best performing genotypes for most important traits influencing the photosynthetic activity under control and heat stress treatments. The most important traits to be focused on are net photosynthetic rates, transpiration rates, and stomatal conductance along with effective photochemical yield of PSII, Coefficient of photochemical yield of PSII, electron transport rate and Fv/Fm ratio which are highly associated with heat stress conditions. Solanum commersonii accessions (BGB003, BGB009) are more likely to be tolerant to heat stress, followed by S. tuberosum 2x (BGB091, BGB093) and S. chacoense (BGB101). The assessment of wild accessions for photosynthetic traits under heat stress is a reliable way to discriminate the most promising sources of abiotic stress resistance even though they have unreliable tuber traits for the breeding of the potato crop.

Irrigation water management practices are the main strategies to improve water productivity. This research work was focused to study the performance of alternate and paired row furrow irrigation systems at three levels of irrigation (100%, 75%, and 50% of crop evapotranspiration) using different water productivity indicators for onion crops. The experiment had six treatments and replicated three times to evaluate the analysis of variance in SAS software. Water productivity indicators like crop water use efficiency, field water use efficiency, and field water expense efficiency were determined through bulb yield and water which were used by the crop. The crop yield was expressed as the total yield of onion bulbs, and crop water use was expressed as crop evapotranspiration (ETc), gross depth of irrigation, and water expense. The estimated maximum values of crop water use efficiency, field water use efficiency, and field water expense efficiency were 11.941, 16.152, and 9.361 kg m−3, respectively, for paired row furrow irrigation with 50% ETc. The performance of the paired row furrow irrigation system in crop yield and water use was better as compared to the alternate furrow irrigation system at all levels of irrigation.

“…One of the policies put forward and included in the SDGs aspect is the water resources management aspect, which is included in the sixth mission, namely clean water and sanitation. Since water resources are essential to human existence, sustainable development is closely related to them (Kilemo, 2022). The primary foundation of civilization is water, which is becoming increasingly scarce in arid regions due to exponential growth (Assaf et al, 2021).…”

This study aims to examine community-based water resources management implemented in Umbul Ponggok Village, Klaten Regency, Central Java, Indonesia, based on the Water Resources Law (2019) and was subsequently modified by the Job Creation Law (2023), which prioritizes the well-being of the local community and in order to achieve sustainable development goals (SDGs), especially the principle of No.-One Left Behind. Community involvement in water resources management is very important. Therefore, communities no longer only act as consumers but also as those who determine their own needs for water resources. One area that has implemented this approach is the community in Ponggok Village, Klaten Regency. Therefore, this study addressed the compliance of the community-based water resource management in Ponggok Village, Klaten Regency, with the existing regulations. The study also determined whether the community complies with the principles of Sustainable Development Goals (SDGs) through a juridical-empirical method. Data was collected through documentation and interviews, and qualitatively analyzed. The result showed that the practices of water resource management in Ponggok Village aligned with existing regulations. However, a notable gap existed in adhering to reporting regulations, attributed to a lack of awareness among the village apparatus. Then, the water resource management in Ponggok Village has fully aligned with the current regulations and the SDGs' principles.
