Abstract. The evapotranspiration-based scheduling method is the most common for irrigation programming in agriculture. There no doubt that estimation of reference evapotranspiration (ETo) a key factor irrigated However, high cost and maintenance agrometeorological stations number sensors required to estimate it make non-plausible, especially rural areas. For this reason, ETo using air temperature, places where wind speed, solar radiation humidity data are not readily available, particularly...
The invasive tomato pest Tuta absoluta (Meyrik) poses a significant threat to global agriculture, often resulting in severe yield losses if not detected and managed early. This study investigates the application of artificial intelligence (AI) develop an automated system for detecting T. lesions on plants. Leveraging open-source computational tools such as Google Colab, research aims provide accessible efficient solution through experiments, without requiring field trials.A curated dataset...
Abstract. The impact of climate change and its relation with evapotranspiration was evaluated in the Duero River Basin (Spain). study shows possible future situations 50 yr from now reference (ETo). maximum temperature (Tmax), minimum (Tmin), dew point (Td), wind speed (U) net radiation (Rn) trends during 1980–2009 period were obtained extrapolated FAO-56 Penman-Montheith equation to estimate ETo. Changes stomatal resistance response increases CO2 also considered. Four scenarios done, taking...
Estimation of reference evapotranspiration (ETo) using air temperature is particularly attractive for places where solar radiation, wind speed, and humidity data are not readily available. In this study, seven temperature-based (TET) models the standardized equation short canopies method were compared. Using only from Yucatán Peninsula, México, Food Agriculture Organization United Nations (FAO)-Penman-Monteith (PMT) model was used to estimate ETo. Results compared with FAO-56 daily ETo...

While evapotranspiration rates are known to increase with higher temperature, other factors in addition rising temperatures also affect (ET). For example, increasing humidity and CO2 concentrations both tend reduce transpiration counteract the temperature effects on ET. As oceans water bodies warm evaporate more into atmosphere, global is likely increase. increase, leaf stomata partially close response maintain concentration inside stomata. Thus, while climate change air effect of could...
Abstract. Vegetation indices based on satellite images, such as the normalized difference vegetation index (NDVI), have been used in countries like USA, Canada and Spain for damaged pasture forage insurance over last few years. This type of agricultural is called satellite-index-based (SIBI). In SIBI, occurrence damage defined normal distributions. this work a area at north Community Madrid (Spain) has delimited by means Moderate Resolution Imaging Spectroradiometer (MODIS) images. A...
Landscape evolution is driven by abiotic, biotic, and anthropic factors. The interactions among these factors their influence at different scales create a complex dynamic. Landscapes have been shown to exhibit numerous scaling laws, from Horton's laws more sophisticated of heights in topography river network topology. This multiscaling analysis has the potential characterise landscape terms statistical signature measure selected. study zone matrix obtained digital elevation model (DEM) (map...
The combination of hydroponics and aquaculture, or aquaponics, normally requires adding fertilizer to recirculated water ensure optimal plant growth, but the effect that on fish welfare has not been studied in detail, especially for small urban coupled aquaponic systems. In this study, a commercial was placed two systems (less than 250 liters each) test its stress levels Nile tilapia (Oreochromis niloticus) compared controls without any fertilizer. Fish production parameters were...

Abstract. In agricultural ecosystems the use of evapotranspiration (ET) to improve irrigation water management is generally widespread. Commonly, crop ET (ETc) estimated by multiplying reference (ETo) a coefficient (Kc). Accurate estimation ETo critical because it main factor affecting calculation and management. The from recorded meteorological variables at weather stations. objective this paper was assessing effect uncertainty due random noise in sensors used for measurement on ETo, net...
The dynamic of rangelands results from complex interactions between vegetation, soil, climate, and human activity. This scenario makes rangeland’s condition challenging to monitor, degradation assessment should be carefully considered when studying grazing pressures. In the present work, we study interaction vegetation soil moisture in semiarid using indices. We aim feasibility negative anomalies as a warning index for or agricultural drought.

Abstract. The dynamic of rangelands results from complex interactions between vegetation, soil, climate, and human activity. In arid semiarid areas, rainfall coefficients variability are over 30 %. This scenario makes rangeland's condition challenging to monitor, degradation assessment should be carefully considered study grazing pressures. the present work, we interaction vegetation soil moisture in rangelands, using indexes. We aim feasibility water (soil drought) as a warning index for...
Water scarcity presents an increasingly urgent challenge with global implications for the production of irrigated vegetables. Among these crops, tomatoes stand out as one most widely cultivated. Given their vulnerability to water stress, it is crucial ensure efficient and sustainable management tomato irrigation. This study aims compare physiological biochemical parameters among three local commercial resilient varieties in response stress rehydration. We subjected plants either two brief...
