Single and basal crop coefficients for estimation of water use of tree and vine woody crops with consideration of fraction of ground cover, height, and training system for Mediterranean and warm temperate fruit and leaf crops
This paper reviews the research on the FAO56 single and basal crop coefficients of fruit trees and vines performed over the past twenty-five years and focus on Mediterranean and warm temperate trees and vines. Two companion papers (López-Urrea et al., (2023) Single and basal crop coefficients for estimation of water use of tree and vine woody crops with consideration of fraction of ground cover, height, and training system for temperate climate fruit crops.

Water Footprint and Water Sustainability of Agroindustrial Avocado Production in a Warm Tropical Climate Municipality: A Case Study in the Michoacan Avocado Belt in Central México
Water is a fundamental resource for ecosystems, humans, and the development of all economic sectors; it is necessary to identify and evaluate its environmental pressures and impacts. The water footprint (WF) is an appropriate indicator for the consumption of water used to produce a product. The present study uses this tool to evaluate the green and blue water requirements and the sustainability of irrigation water use for agroindustrial avocado production in Ziracuaretiro, Michoacán (2012–2021).
Avocado Water Footprint for Two Municipalities in Michoacán, Mexico: A Research of the Blue and Green WF
The Water Footprint (WF) is an indicator used to determine good practices for efficiently using water in human activities. This work evaluates the green (rainfed) and blue (irrigation) water footprint of avocado cultivation in the municipalities of Acuitzio (2012–2016) and Morelia (2016–2020) in Michoacán, Mexico. Likewise, the water stress of irrigation water use is analyzed, linking the blue WF with the volumes of concessions for agricultural use. The results revealed that the
IS-SAR: an irrigation scheduling web application for Hass avocado orchards based on Sentinel-1 images
As the Hass avocado crop expands exponentially in Colombia, concern about its increasing water use is on the rise. This research aimed to develop IS-SAR, a free-access web application to schedule irrigation for Valle del Cauca’s Hass growers. We calibrated the water cloud (WCM) and artificial neural network (ANN) models using field data measurements from Hass avocado orchard plots in Valle del Cauca (Colombia) and Sentinel 1 (S1) satellite imagery measurements and evaluated their performance
Evaluation of leaf carbon isotopes and functional traits in avocado reveals water-use efficient cultivars
Plant water-use efficiency (WUE) describes the ratio of carbon gain to water loss during photosynthesis. It has been shown that WUE varies among crop genotypes, and crops with high WUE can increase agricultural production in the face of finite water supply. We used measures of leaf carbon isotopic composition to compare WUE among 24 cultivars of Persea americana Mill (avocado) to determine genotypic variability in WUE, identify potentially efficient cultivars, and to better understand how breeding
The impact of tree phenology on the response of irrigated avocado: The hysteretic nature of the maximum trunk daily shrinkage
The goal of this study was to check the feasibility of the use of dendrometers to monitor water stress levels in avocado trees (Persea americana Mill, cv. Hass) during the period of 2015–2017. This water stress was generated naturally during events of high vapor pressure deficit (VPD) that normally take place during the Israeli spring (May) and late autumn (September). It was also generated artificially by considering two irrigation regimes, one providing the crop water needs estimated using lysimeter
