“…As moisture is a critical component of productive soils, it is important to be able to monitor soil MC across a landscape. In agricultural settings, the monitoring of soil MC allows the efficient allocation of resources (e.g., irrigation water), synchronisation of planting and harvest activities with climatic conditions, the prevention of salinisation and the maintenance of soil moisture levels for optimal crop growth, disease management and many other purposes [1][2][3][4][5]. In engineering scenarios, soil moisture is relevant to the behaviour and structural integrity of soils [6][7][8].…”

The ability to precisely monitor soil moisture is highly valuable in industries including agriculture and civil engineering. As soil moisture is a spatially erratic and temporally dynamic variable, rapid, cost-effective, widely applicable, and practical techniques are required for monitoring soil moisture at all scales. If a consistent numerical relationship between soil moisture content and soil reflectance can be identified, then soil spectroscopic models may be used to efficiently predict soil moisture content from proximal soil reflectance and/or remotely sensed data. Previous studies have identified a general decrease in visible–NIR soil reflectance as soil moisture content increases, however, the strength, best wavelengths for modelling, and domain of the relationship remain unclear from the current literature. After reviewing the relevant literature and the molecular interactions between water and light in the visible–NIR (400–2500 nm) range, this review presents new analyses and interprets new 1 nm resolution soil reflectance data, collected at >20 moisture levels for ten soil samples. These data are compared to the results of other published studies, extending these as required for further interpretation. Analyses of this new high-resolution dataset demonstrate that linear models are sufficient to characterise the relationship between soil moisture and reflectance in many cases, but relationships are typically exponential. Equations generalising the relationship between soil MC and reflectance are presented for a number of wavelength ranges and combinations. Guidance for the adjustment of these equations to suit other soil types is also provided, to allow others to apply the solutions presented here and to predict soil moisture content in a much wider range of soils.

“…Water savings often benefit the original water users and their immediate neighbours more than nature and society. This challenges the assumption that water conservation in agriculture directly benefits broader ecological and societal needs (see literature on the Paracommons; Lankford, 2013;Lankford and Scott, 2023). However, this generalisation is not always true, as the fate of these losses, before and after changes to irrigation technology and efficiency, can be unpredictable and variable (Lankford et al, 2020;Lankford, 2023).…”

A major challenge for agricultural water management (AWM) in the 21st century is to feed a growing population in the face of increasing intersectoral resource competition, evolving diets, degradation, pandemics, geopolitical conflicts and climate change. This has to be achieved within the planetary boundaries and without compromising the livelihood and environmental (ecosystem) objectives linked to water, including provisioning, supporting and regulating services. This paper uses a systems and nexus lens to unravel the centrality and complexities in AWM, with particular emphasis on the interconnected dimensions and objectives of AWM, as well as its practices and technologies. AWM exists beyond water and food with linkages to human and environmental well‐being. AWM needs to catalyse transformation and integrate approaches across systems, users and scales to meet its objectives in a changing climate. It must provide perspectives beyond productivity, managing water risks and safeguarding food security – as important as these are – and integrate our understanding of the interconnected climate, land, water, food and ecosystems to address planetary health outcomes. By doing so, AWM could catalyse contextualised, equitable, innovative solutions that acknowledge local socio‐economic and institutional structures and limitations while catalysing sustainable development and climate resilience.
