Accurate estimates of how soil water stress affects plant transpiration are crucial for reliable land surface model (LSM) predictions. Current LSMs generally use a water stress factor, β, dependent on soil moisture content, θ, that ranges linearly between β = 1 for unstressed vegetation and β = 0 when wilting point is reached. This paper...

En este trabajo se describe un proyecto de innovación docente para la mejora de los procesos de enseñanza-aprendizaje de Hidráulica en el Grado de Ingeniería Agrícola. El proyecto consistió en plantear, en dos etapas diferenciadas, metodologías de aprendizaje basadas en proyectos y en el trabajo en equipo. En la primera etapa, un estudiante de...

Urban development is causing environmental and social concerns that are compromising human welfare and cities sustainability. New urban greening concepts are appearing in order to mitigate these problems in a sustainable and natural way. Vertical greening systems can be defined as structures which allow vegetation to spread over a building...

Living walls are becoming popular solutions to alleviate negative effects of urban development. They are vertical greening systems which allow vegetation to spread across a wall surface in order to cover a building facade or an interior wall. Due to their characteristics, irrigation becomes essential but the infrastructure and management...

Branch/tree-level measurements of carbon (C)-acquisition provide an integration of the physical and biological processes driving the C gain of all individual leaves. Most research dealing with the interacting effects of high-irradiance environments and soil-induced water stress on the C-gain of fruit tree species has focused on leaf-level...

Living walls are systems that allow the development of vegetation in a vertical surface attached to building facades or indoor walls. Traditionally, they have behaved as 'passive' bio-filters, but new approaches and technologies are moving towards their integration within the building's air conditioning and ventilation systems. In an Active...

Para un manejo adecuado del riego es necesario tener información disponible de una manera rápida y sencilla. Gracias a los avances tecnológicos, esto es posible. En este trabajo se han utilizado imágenes captadas mediante una cámara térmica montada sobre un vehículo aéreo para evaluar el estado hídrico de un cultivo de remolacha azucarera en...

Remote and non-destructive estimation of leaf area index (LAI) has been a challenge in the last few decades as the direct and indirect methods available are laborious and time-consuming. The recent emergence of high-throughput plant phenotyping platforms has increased the need to develop new phenotyping tools for better decision-making by...

Dataset generated in the work "Impact of Irrigation Management Decisions on the WaterFootprint of Processing Tomatoes in Southern Spain" whose main objective was to determine the water footprint of processing tomatoes grown in southern Spain under different drip irrigation methodologies.

Living walls (LW) are vertical greening systems that are becoming popular due to their multiple social and environmental benefits. When LW are installed indoors, a lightening system is often required to ensure an appropriate plant development. This work assesses the performance of three artificial lighting systems on six indoor LW [0.7 m (wide)...

Characterization of the spatial variability in tree water status is a prerequisite to conduct precise irrigation management within an orchard. This study assessed the suitability of a crop water stress index (CWSI) derived from high-resolution aerial thermal imagery to estimate tree water status variability in super high density (SHD)...

Irrigation plays a very important role in a Mediterranean garden. In spite of this, there are not many studies assessing irrigation water management of landscapes. Moreover, historic gardens represent a special challenge due to their unique characteristics. The aim of this work is the characterization and evaluation of water management in a...

Strawberry (Fragraria x ananassa) is a crop affected by various soil-borne fungal pathogens with mostly non-specific foliar symptoms and often requiring laboratory isolation for correct diagnosis. Moreover, these nonspecific foliar symptoms, appreciated by the human eye, appear after some time following infection by the pathogen. Early...

Canopy temperature has been proposed as a relevant variable for crop water stress moni toring. Since crop temperature is highly influenced by the prevailing climatic conditions, it is usually normalized with indices such as the crop water stress index (CWSI). The index requires the use of two baselines that relate canopy temperature under...

Characterization of the spatio-temporal variability of tree water status is a prerequisite to conducting precise irrigation management in fruit tree orchards. This study assessed the suitability of a crop water stress index (CWSI) derived from high-resolution aerial thermal imagery for estimating tree water status variability in super high...

The water footprint is an increasingly demanded environmental sustainability indicator for certifications and labels in agricultural production. Processing tomatoes are highly water-intensive, and existing studies on water footprint have uncertainties and do not consider the impact of different irrigation configurations (e.g., surface drip...

Current land surface schemes in weather and climate models make use of the so-called coupled photosynthesis–stomatal conductance (A–gs) models of plant function to determine the surface fluxes that govern the terrestrial energy, water and carbon budgets. Plant physiology is controlled by many environmental factors, and a number of complex...
