Abstract Droughts are a major global natural hazard, creating negative environmental and socio-economic impacts across broad spectrum of sectors. However, agriculture is often the first sector to be impacted due prolonged rainfall shortages reducing available soil moisture reserves with consequences for both rainfed irrigated food crop production livestock. In UK, recent droughts in 2018 2022 have highlighted vulnerability agricultural horticultural sectors since most entirely dependent on capricious nature summer rainfall. Surprisingly, despite recognition agronomic economic risks, there remains paucity evidence multi-scalar drought, including yields quality, financial implications farming fresh produce supply chains.

Resolving the paradoxes of irrigation efficiency: Irrigated systems accounting analyses depletion-based water conservation for reallocation

Agricultural Water Management, Год журнала: 2023, Номер 287, С. 108437 - 108437

The irrigation efficiency paradox says that raising the of systems, thereby reducing return flows, either gives no change in water depletion or it raises via increased evapotranspiration and irrigated area. While this can occur, there are problems associated with it. It eludes precise explanation characterisation; be confused other hydrology paradoxes; is one several ways areas increase; over-emphasises role flows; relies on variables (usually unstated) being uncontrolled; inverted to reduce depletion; may mistakenly guide conservation systems. Addressing these concerns, a comprehensive predictive model called Irrigated Systems Accounting (ISA) analyses undergoing based accounts for soil-crop evapotranspiration, (IE), practices infrastructure, withdrawals, depletion, crop production reallocation. By using more calculi than current accounting, ISA; resolves predicts how an system changes its aggregate area primary, expansion reuse zones; reveals non-IE factors drive up but not necessarily depletion. Compiling all zonal reductions derived reallocated users without cutting production. paper concludes hazards policy if exclusively tied together imprecise characterisations draw accounting models containing few terms relationships.

Abstract. Despite recent studies emphasising the dual human and physical nature of droughts, there is a lag in advancing this insight drought monitoring early warning systems (DEWSs). These mainly depend on hydro-climatic indices often overlook experiences affected communities, resulting gap. This study introduces efficacy matrix (MEM) to assess alignment between officially monitored data, relevant impacts, actual rural community northeastern Brazil, which we investigated through interviews. The MEM revealed “drought challenges”, composed mismatches blind spots official data local experiences. Mismatches stem from varying spatial temporal levels; arise diversity resilience strategies, or vulnerabilities, influencing impacts. What define as gap” results tendency prioritise specific pragmatic levels over comprehensive approach. We posit that first step bridging gap can draw inspiration drought-impact-monitoring initiatives, are focused continuous non-extreme events by municipal technical extension officers. However, ultimately remains conditional adaptation DEWS frameworks accommodate integration qualitative representing drought-related context.

Analyzing the spatiotemporal characteristics of meteorological droughts (MD) and agricultural (AD) their propagation in different climate zones is important for effective drought management, adaptation, food security. This study takes a unique approach by comparing irrigated rainfed croplands. A comprehensive framework developed using indices, statistical analysis, trend tests, wavelet transforms. The evolution patterns, trends, correlations MD AD Xinjiang Middle-lower Yangtze Plain (MYP) are investigated. main results showed that severe events (e.g., 2005–2009 MYP 2004–2009) significantly impacted systems, leading to decline vegetation condition. Long-term irrigation can substantially alleviate under conditions. From 2000 2019, on croplands continuously improved, while deteriorated during events. In contrast, although overall was mitigated, benefits were only evident periods weakened after 2013. Correlation analyses revealed mechanisms between croplands, highlighting key role local conditions spatial heterogeneity determining efficiency. findings provide guidance optimizing management strategies, planning, sustainable water resource management.
