During the last thirty years, many farmers and collective irrigation institutions have replaced their traditional gravity systems with modern drip systems, as a result of water-saving policy promoted by numerous states international organisations. The scientific-technical paradigm that associated water-savings this process technological change has collapsed in two decades led to position In research, we focus on adoption Acequia Real del Júcar (València, Spain). We analyse how estimation allocation expected water savings changed different planning instruments, it been perceived actors involved process. research also focused co-design assessment measures correct impacts change, locally Albufera wetland, located immediately downstream abovementioned irrigable area. is based documentary review participatory action research. results show emerging concept rebound effect permeating too slowly from academia users, there need stimulate innovative decision-making achieve more rigorous adapt environmental planning. pioneering which first sign materialisation efficiency paradigm.

The iGains4Gains model guides irrigation water conservation and allocation to enhance nexus gains across water, food, carbon emissions, and nature

Deleted Journal, Год журнала: 2025, Номер 2(1), С. 015014 - 015014

Abstract This paper introduces and applies iGain4Gains, an Excel-based model, to reveal how changes water conservation allocation, irrigation technology, can produce four nexus gains. These gains are; reduced aggregate consumption, sustained crop production, lower carbon emissions, enhanced availability for nature. We developed the model with limited data hypothetical future scenarios from Amman–Zarqa basin in Jordan. Given its significant urban demands difficult decisions regarding allocation choices, this is a highly appropriate case study. The paper’s primary aim demonstrate iGains4Gains rather than build accurate hydrological of basin’s resources. addresses two critical questions increased efficiency. First, efficiency other factors, such as irrigated area, be applied achieve real savings while maintaining ensuring greenhouse gas emission reductions, ‘freeing’ nature? Second, insight that distributive/allocative act, we ask who between paracommoners (the proprietor system, neighbouring systems, society, nature) benefits hydrologically efficiency? Recognising are not always linear, positive predictable, reveals achieving all simultaneously difficult, likely leading trade-offs consumption rebounds or emissions. Demonstrated by use at workshop Jordan February 2024, used students, scientists decision-makers, explore understand connected management. concludes recommendations governing agriculture basins where large volumes withdrawn depleted irrigation.

Abstract As water‐related ecosystem services (WRES) encounter unprecedented threats with climate change and human activities, it is important to understand the impact of variations in supply demand for WRES on Sustainable Development Goals (SDGs). Previous studies commonly overlooked water quality water‐use sectors when using comprehensive supply‐demand index (SDI com ), defined as difference between demand, leading challenges applying estimation SDGs assessment. We constructed a refined framework WRES, categorizing by sectors. It allows calculation ref addressing limitations SDI . Our findings demonstrate that could be effectively employed assess rectify overestimation case study Xinjiang. The relationship resources indicates surpluses domestic industrial use deficits agricultural ecological use, latter worsening. projected higher scenario SSP2‐4.5 high growth rate irrigation efficiency. suggested informed decisions based SDG‐specific targets either maintain or enhance SDG progress scores. proposed established quantitative link well‐being, providing applicable insights other service assessments regions.

Integrating hydrologic modeling and satellite remote sensing to assess the performance of sprinkler irrigation

Geo-spatial Information Science, Год журнала: 2024, Номер 27(3), С. 934 - 952

Опубликована: Май 3, 2024

Improving irrigation water management is a key concern for the agricultural sector, and it requires extensive comprehensive tools that provide complete knowledge of crop use requirements. This study presents novel methodology to explicitly estimate daily gross net requirements, actual use, efficiency center pivot systems, by mainly utilizing Sentinel-2 MultiSpectral Instrument (MSI) imagery at farm scale. ETMonitor model adapted (as sum canopy transpiration evaporation intercepted from soil) daily/10-m resolution, benefiting high-resolution data thus assess The requirement estimated loss, including droplet directly into air during application before droplets fall on interception loss. method was applied pilot farmland with two major crops (wheat potato) in Inner Mongolia Autonomous Region China, where modern equipment appropriate methods are deployed efficient use. showed good agreement ground observations, e.g. determination coefficients range 0.67 0.81 root mean square errors 0.56 mm/day 1.24 wheat potato when comparing evapotranspiration measurement eddy covariance system. It also losses total irrigated volume were 25.4% 23.7% potato, respectively, found allocation insufficient meet this area. suggests amount inherent system, which imply necessity improve practice more efficiently.

Irrigation is more than irrigating: agricultural green water interventions contribute to blue water depletion and the global water crisis

Water International, Год журнала: 2024, Номер 49(6), С. 760 - 781

Опубликована: Авг. 5, 2024

Reflecting on the 2023 assertion by Global Commission Economics of Water that depletion blue water irrigation contributes to global crisis, we critique two previous contributions one its authors, Johan Rockström. First, bridge agro-meteorological drought, rainfed (green water) farmers should irrigate. If not regulated, this increases withdrawals and depletion. Second, continuum agricultural management is a field-scale emphasis rainfall and/or irrigating top up soil moisture. This hinders taking multi-scale systems approach resolve inequitable impacts.

The paracommons of competition for resource savings: Irrigation water conservation redistributes water between irrigation, nature, and society

Resources Conservation and Recycling, Год журнала: 2023, Номер 198, С. 107195 - 107195

Опубликована: Сен. 11, 2023

Based on understandings of a natural resource commons, we examine the competition for redistributed irrigation water following conservation. A 'paracommons' is characterised by an interconnected hydrology whereby changes to proprietor's management alters its distribution into different fractions/dispositions thereby adjusting allocations four paracommoners; including proprietor conserving water, immediate neighbour, society and nature. The topic important given volumes potentially involved in savings; example, 15% reduction annual depletion area 30,000 hectares can notionally meet domestic demands one million people at 150 l/day/pp. However, this illustration, seeming indicate that conservation results sizeable predictable outcomes, hides how savings are captured by, or flow to, paracommoner within interlinked system. Using data from Mendoza, Argentina, employ model 12 scenarios conservation-driven reallocation among paracommoners, conclude with generalizable lessons.

Abstract Efficient agricultural water management (AWM) practices enhance crop productivity and promote climate change adaptation resilience initiatives, particularly in smallholder farming systems. Approximately 90% of sub-Saharan Africa’s (SSA) agriculture is rainfed under farmers who constitute about 60% the continent’s population depend on for their livelihoods. While AWM central to African agenda, knowledge fragmented, making it challenging operationalize regional initiatives at country levels. Therefore, this study sought review status technologies Africa provide guidelines, scenarios, investment plans guide prioritization operationalization Union’s irrigation development (AU-IDAWM) initiative. The initiative proposes four developmental pathways; 1—improved control watershed rain-fed farming, 2—farmer-led irrigation, 3—irrigation scheme modernization, 4—unconventional use irrigation. preferred reporting items systematic reviews meta-analyses approach guided literature review. indicates that most production systems are mainly pathways 1 2, which dictate subsequent practices.
