“…In recent years, many studies have focused on sustainable water management, which includes diagnosing challenges, opportunities, and priorities for implementing sustainable water resource management under climate change [45][46][47], planning and evaluating sustainable solutions using multiple criteria [48,49], and applying various technologies and management tools [50][51][52][53][54] at different hierarchical levels and in different industries and countries. Our findings can be used in Ukraine to diagnose and plan sustainable water management measures in order to improve the resilience (both of particular production systems and entire regions), while the comprehensive assessment methodology of water resource efficiency can be applied in other regions and countries as well.…”

Management based on sustainable approaches increases the resilience of systems in which they are implemented. The following study explores the sustainability and efficiency of water management in the regions of Ukraine and the role of these factors in its resilient development. The study conducts a bibliometric analysis of sources on sustainable water management, a comprehensive assessment of water resource efficiency in the regions of Ukraine, identifies and maps regional differences, and analyzes their dynamics over the period 2016–2020. The assessment shows that almost half of the regions (48.3%) have sufficient water management efficiency, 40.8% are very high, and 10.9% are average. Most regions (79.2%) maintained the same level of water resource efficiency. The Kharkiv region was examined in-depth, revealing higher water losses during transport and municipal/household sectors than the national average. Based on the assessment’s results, a differentiated approach to sustainable water management should be taken, depending on the type of regions. For regions with a very high and sufficient level of water efficiency, strategies to maintain the achieved positions should be implemented, while for regions with an average level of efficiency, strategies to improve the respective indices should be implemented. These research findings and policy recommendations can be utilized to guide policy-makers aiming to enhance the economic mechanism of sustainable water management at regional and national levels and improve their resilience to face the intensifying challenges.

“…The cultivation of these crops across various climates, particularly in arid regions, poses complex challenges due to limited water resources. As emphasized by recent studies [68,69], water scarcity and effective water management have become pivotal aspects of agricultural sustainability in arid and semiarid zones. Specifically, the results indicate that, in extremely dry climates, the WFP linked to cucurbit cultivation notably surpasses that of other climates.…”

Water resource management has emerged as a pivotal concern within arid regions in recent times. The water footprint (WFP) index stands out as a principal gauge for facilitating comprehensive watershed management. This study endeavors to compute the WFP of diverse agricultural products encompassing major crops, orchards, cucurbits, and medicinal plants across arid regions. This research focuses on three distinct climate scenarios: the Shazand Plain with a semidry climate, the Khomein Plain characterized by a dry climate, and the Saveh Plain exhibiting a very dry climate. This study also seeks to ascertain the climate most conducive to cultivating crops from a WFP (green, blue, and gray) perspective. To achieve these objectives, this study employed the CropWat family software to determine crop water requirements, as well as considering crop yield and relevant parameters for calculations. The findings of the investigation unveiled that the cultivated areas in the respective climates amounted to 19,479 ha (semidry), 18,166 ha (dry), and 41,682 ha (very dry). These areas were allocated as follows: 88%, 85%, and 55% for crops; 11%, 13%, and 40% for orchards; and 1%, 2%, and 5% for cucurbit crops. Importantly, the very dry climate was predisposed to allocating more land for low-water-demand orchards. Among the major crops, wheat occupied 44%, 39%, and 43% of the total areas in the semidry, dry, and very dry climates, respectively. Analyzing the overall agricultural output in these climates, it was revealed that over 79%, 69%, and 66% of production correlated with crops; 17%, 19%, and 22% with orchards; and 4%, 12%, and 12% with cucurbits, respectively. In terms of water consumption, maize and apples emerged as the highest performers, with varying consumption patterns across different crops. Interestingly, canola exhibited a substantially higher WFP, surpassing wheat and barley by 56.48% and 58.85%, respectively, in dry climates. Cucurbit crops, on the other hand, displayed a lower WFP in dry climates, which could potentially encourage their cultivation. The influence of climate warming on canola’s WFPgray introduced complexity, challenging the conventional correlation between WFP and yields. Medicinal plants consistently demonstrated lower WFP values, underscoring the need for deliberate and considerate cultivation decisions in this regard.

“…This highlights a need for long term soil monitoring within the TSA wetted footprint and contributing area to understand changes in soil properties. TSAs could be used to alleviate soil issues such as hydrophobicity through rewetting (Doerr et al, 2000;Horne & McIntosh, 2000;Rakhmatulina & Thompson, 2020) or support crop production in dry regions by recapturing nutrient rich sediments and increasing soil moisture (Bagula et al, 2022;Biazin & Stroosnijder, 2012;Wang et al, 2022). Better knowledge of how all TSA types (Figures 1,2 and Table 1) work across a range of soil, physical and management conditions under various states of wetness will help inform future TSA design and management, ensuring TSAs remain effective in the context of a changing climate.…”

Mitigating floods and attenuating surface runoff with temporary storage areas in headwaters

Temporary storage areas (TSAs) represent a category of soft-engineered naturebased solutions that can provide dispersed, small-scale storage throughout a catchment. TSAs store and attenuate surface runoff, providing new additional storage during flood events. The need for such additional catchment storage will become more urgent as the frequency and magnitude of extreme hydrological events increases due to climate change. Implementation of TSAs in headwater catchments is slowly gaining momentum, but practitioners still require further evidence on how such measures function during flood events. This review focuses on the role of relatively small-scale (<10,000 m 3 ) TSAs in headwater catchments for flood risk management. It also explores the potential wider benefits for implementing these as part of an integrated catchment management approach. TSA flood mitigation effectiveness is primarily determined by the TSA's available storage prior to the event. At the local scale, this can be represented by the relationship between TSA inputs, outputs and total storage. Factors influencing the local functioning and effectiveness of TSAs are discussed, with potential considerations for optimizing future TSA design and management. Hydrological models have suggested that TSAs could be used to effectively attenuate high magnitude events. However, future considerations should involve addressing the lack of empirical evidence showing TSA catchment scale effectiveness and how local TSA functioning might change in time. Small-scale headwater TSAs offer a holistic and sustainable approach to catchment management that can deliver both local benefits to landowners and wider flood risk mitigation for society.
