The impact of agricultural management on selected soil properties in citrus orchards in Eastern Spain: A comparison between conventional and organic …

2017

The agricultural management of citrus orchards is changing from flood irrigated managed orchards to drip irrigated organic managed orchards. Eastern Spain is the oldest and largest European producer of citrus, and is representative of the environmental changes triggered by innovations in orchard management. In order to determine the impact of land management on different soil quality parameters, twelve citrus orchards sites were selected with different land and irrigation management techniques. Soil samples were taken at two depths, 0-2. cm and 5-10. cm for studying soil quality parameters under the different treatments. Half of the studied orchards were organically managed and the other si…

Effects of Biochar on Irrigation Management and Water Use Efficiency for Three Different Crops in a Desert Sandy Soil

2020

This paper aimed at investigating if the application of biochar (BC) to desert sand (DS) from the United Arab Emirates (UAE), characterized by a very poor soil-water retention (SWR) and by a very low value of the maximum water available for crops (AWmax), could positively affect soil water balance, by reducing the irrigation needs (VIRR) and improving the irrigation water use efficiency (IWUE) and the water use efficiency (WUE). The analysis was performed for three crops, i.e., wheat (Triticum aestivum), sorghum (Sorghum vulgare) and tomato (Lycopersicon esculentum). BC was applied to the DS at different fractions, fBC (fBC = 0, 0.091, 0.23 and 0.33). Drip irrigation was adopted as a highly…

L'incremento della sostenibilità ambientale attraverso una corretta gestione dell'irrigazione.

2014

Lo scopo di questo lavoro è quello di mettere a punto, a partire dalle informazioni territoriali quali caratteristichemeteorologiche e pedologiche, uno studio capace di valutare la sostenibilità della gestione irrigua in tre ipotetiche parcelle sperimentali individuate nel territorio del sottobacino Iudeo-Bucari (TP). Sitratta di tre vigneti che rappresentano per caratteristiche morfologiche e gestionali l'intero sottobacino, ovvero una delle aree maggiormente vitate della Sicilia. Il fine è valutare la sostenibilità della gestione irrigua in termini di risparmio energetico, attraverso l'applicazione del modello di bilancio idrico FAO 56. Questo tipo di studio pone le basi per la redazione …

Environmental, Agricultural, and Socioeconomic Impacts of Salinization to Family-Based Irrigated Agriculture in the Brazilian Semiarid Region

2020

Soil salinity is one of the major abiotic factors causing a serious threat to global food security, mainly in arid and semiarid regions. Salinity brings socioeconomic impacts associated with low crop productivity and devaluation of agricultural lands. In this chapter, we approach agricultural, environmental, and socioeconomic impacts of soil salinization. We also report two case studies from irrigated areas of the Brazilian semiarid, where previously cultivated lands were abandoned due to increased soil salinity. A survey of the published literature showed that soil salinity became a global problem that is accelerated by human activities such as deforestation and lack of irrigation manageme…

Cambio tecnológico, privatización y recuperación de la autogestión comunitaria del riego. El caso de Senyera (València)

2018

[ES] Los procesos de cambio de tecnología del riego están facilitando la penetración silenciosa de la empresa privada en los sistemas de gestión colectiva del riego en numerosos lugares de España y otros países mediterráneos. Este artículo analiza este fenómeno a partir del caso de estudio de Senyera (València), siguiendo la privatización, la disputa y la posterior recolectivización de la gestión por parte de los usuarios del riego. El trabajo muestra como la privatización menoscaba la autonomía de los agricultores y eleva los costes de gestión en un contexto de escasa transparencia. También revela la capacidad de los regantes para reelaborar su pasada acción colectiva, dando lugar a una nu…
