Abstract The benefits of an integrated geographical information system (GIS) and a geostatistics approach to accurately model the spatial distribution pattern precipitation are known. However, determination most appropriate geostatistical algorithm for each case is usually neglected, i.e. it important select best interpolation technique study area obtain accurate results. In this work, ordinary kriging (OK), simple (SK) universal (universal kriging) methods compared with three multivariate...

Fire severity is a key factor for management of post-fire vegetation regeneration strategies because it quantifies the impact fire, describing amount damage. Several indices have been developed estimation fire based on terrestrial observation by satellite imagery. In order to avoid implicit limitations this kind data, work employed an Unmanned Aerial Vehicle (UAV) carrying high-resolution multispectral sensor including green, red, near-infrared, and red edge bands. Flights were carried out...

The economic and environmental sustainability of extensive livestock production systems requires the optimisation soil management, pasture animal grazing. Soil compaction is generally viewed as an indicator degradation processes a determinant factor in crop productivity. In Montado silvopastoral ecosystem, characteristic Iberian Peninsula, trampling mentioned variable to consider compaction. This study aims: (i) assess spatial variation profile 0-0.30 m deep layer over several years; (ii)...

The objective of this study was to determine how application dolomitic limestone and stocking methods (continuous or deferred stocking) affect the soil compaction, sheep grazing location, height, nutritional value pastures when pasture growth rate is at its maximum. A 4 ha field Mitra farm—University Évora—was divided into four plots: P1 P2—without limestone, continuous (CS), (DS), respectively—and P3 P4—with DS (2.3 AUE), CS (1 respectively. In DS, animals were placed removed from plots...

The dehesa, recognised as the most extensive High Natural Value Agricultural System in Europe, is one of main natural and economic resources Southwest Iberian Peninsula therefore Europe. Numerous studies indicate that an increase temperatures (Tm) a reduction precipitation (P) are expected due to climate change, especially this area. This would lead Evapotranspiration (ETP), which represents water requirements plants, reduced rainfall.  Utilizing time series data on climatic...

This study analyses the temporal trends (1981-2022) of two widely used aridity indices: De Martonne index (IDM) and FAO (IF) in main grassland agroforestry areas (Dehesa) Iberian Peninsula, context current climate change. It is essential to understand its order assess sustainability these agricultural systems, especially a global warming scenario. The annual IDM IF have been determined Dehesa southwest Peninsula (Spain Portugal). mean was 20.2 (corresponding Mediterranean-type climate),...

In the current context of climate change, understanding chilling requirements necessary for breaking dormancy and flowering in fruit trees is crucial selecting suitable cultivars different geographical locations. Recent data essential precise estimates regarding area's suitability. Temperature from 72 weather stations, spanning period 1975 to 2015, were analyzed using three models assess winter accumulation (Chilling Hours, Utah Model, Positive Model). This aimed estimate spatial pattern...

Climate is the main factor influencing winegrape production in a region, making viticulture highly sensitive to climate change. The increase atmospheric temperature due change affects both yield and composition. Given importance of Extremadura (southwestern Spain) terms area it covers socio-economic benefits generates, crucial understand impact that may have on region. aim this study analyze high-resolution projections under two different scenarios, considering several future periods up end...

This study investigates the spatial–temporal dynamics of vegetation indices in olive orchards across two traditionally rainfed regions Iberian Peninsula, namely “Trás-os-Montes” (TM) agrarian region Portugal and Badajoz (BA) province Spain, response to drought conditions. Using satellite-derived indices, derived from Harmonized Landsat Sentinel-2 project (HLSL30), such as Normalized Difference Moisture Index (NDMI) Soil-Adjusted Vegetation (SAVI), this evaluates impact periods on tree...

A quantification of the overall soil fertililty potential should integrate main physical and chemical properties, with different units.The formulation Rasch model is proposed as an instrument to measure fertility potential, integrating 11 properties (clay, silt sand content, organic matter -OM-, pH, total nitrogen -TN-, available phosphorus -AP-and potassium -AK-, cation exchange capacity -CEC-, deep -ECdand shallow -ECs-soil apparent electrical conductivity, 0-90 0-30 cm depth respectively)...

The intensification of the Montado mixed ecosystem (agro–silvo–pastoral) is a current endeavor in context promoting sustainability extensive livestock production Mediterranean region. Increased pasture productivity and animal involves use technologies to monitor spatial variability implement differentiated management grazing, fertilization or soil amendment. An intermediate step should lead identification demarcation areas with similar characteristics (soil and/or crop development), known as...

In the current context of increasing costs production factors, it is essential to optimize management available resources, seeking incorporate technologies that improve knowledge variables involved in agronomic process. The aim this study define and validate zones (MZ) a 3.3 ha vineyard located near Évora, South Portugal. A contact sensor (“Veris 2000 XA”) was used map soil apparent electrical conductivity (ECa) precision altimetric survey field carried out with global navigation satellite...

Climate change, especially the trend towards global warming, will significantly affect hydrological cycle, leading to a general reduction of water available for agriculture. In this scenario, it is essential that research should focus on development ‘water saving’ techniques and technologies. This work summarizes methodology followed in project large scale implementation variable rate irrigation (VRI) systems using center pivots corn crop. based technologies monitoring (i) soil electrical...

Climate change is having many effects in the agricultural sector, which are being studied worldwide. Undoubtedly, warmer winters and earlier springs produce changes frost regimes severity that will affect sustainability of production area. The Mediterranean region Iberian Peninsula (IP) among areas where greatest impact climate expected. Daily data from 68 weather stations IP belonging to European Assessment Dataset (1975–2018) were used conduct a spatiotemporal study regime. variables...

Water is a limiting factor and to adopt the most appropriate agronomic strategy it necessary know water status. The objective (i) analysing of influence different treatments on canopy temperature in vineyards with thermal camera an unmanned aerial vehicle (UAV), (ii) vineyard potentials pressure chamber, (iii) advanced technical feasibility analysis crop monitoring. control treatment (T07) cv.

Cixiid planthoppers (Hemiptera: Fulgoromorpha: Cixiidae) are considered to be important economic pests because of their ability transmit phloem‐restricted prokaryotes causing emerging plant diseases worldwide. However, little information is available on the biology and ecology such species. This case for Pentastiridius leporinus (Linnaeus), a cixiid planthopper reported live common reed across Countries Central Northern Europe. in east France, same species appears complete its life cycle...
