Irrigation significantly contributes to total water withdrawal and exhibits considerable spatial and temporal variability, particularly in more humid regions. This variability is caused by climate, soil properties, and crop water requirements. However, time series of high-resolution, crop-specific irrigated area data remain scarce in Europe. We developed and applied a method to harmonize input data on crop types and irrigation to obtain the European Crop-specific IRrigated Area (ECIRA) dataset, providing annual 1-km gridded crop-specific irrigated area for 16 crop types across 28 European countries for 2010-2020. The ECIRA dataset effectively identifies crop-specific irrigated hotspots, aligns with subnational census data, and strongly agrees with LUCAS field observations and other survey-based crop-specific irrigation area datasets. However, caution is needed for region- and location-specific studies, as the Europe-wide scope of ECIRA entails a trade-off between local details and overall consistency. It can be used in assessments of crop productivity and crop water use, as input in land surface-, crop-, and hydrological modeling, in climate impact studies and to support improved water resources management.

Organic farming is expanding globally in response to the growing need for more sustainable food production. However, assessing both direct and indirect environmental effects is essential for identifying effective practices. This paper employs a Life Cycle Assessment (LCA) using a cradle-to-farm gate framework to evaluate the environmental effects of non-chemical weed control methods (row-cultivator, finger-weeding, flaming, and hand-weeding) in combination with four fertilization treatments (compost at 10, 30, and 60 m ha, and chemical fertilizer) in the production of four organic field crops grown under irrigated conditions in a Mediterranean climate.

Climate change intensifies pressures on agricultural water resources, particularly in arid and semi-arid regions. This study evaluates the interplay between climate variability and agricultural water footprint (WF) dynamics in Türkiye from 1990 to 2019, integrating trend analyses of WF components, virtual water content (VWC), and climate parameters. We assessed temporal trends and correlations using the Mann-Kendall test, Sen's slope estimator, and Innovative Trend Analysis, focusing on 11 major crops.

Climate and global changes alter natural resources demand and availability for meeting societal needs. Agricultural water use remains a priority, as agriculture remains the first freshwater consumer. Accurate mapping of irrigated and rainfed crops is crucial in agro-hydrological modelling for water management and policy.

Crop production is among the most extensive human activities on the planet - with critical importance for global food security, land use, environmental burden, and climate. Yet despite the key role that croplands play in global land use and Earth systems, there remains little understanding of how spatial patterns of global crop cultivation have recently evolved and which crops have contributed most to these changes. Here we construct a new data library of subnational crop-specific irrigated and rainfed harvested area statistics and combine it with global gridded land cover products to develop a global gridded (5-arcminute) irrigated and rainfed cropped area (MIRCA-OS) dataset for the years 2000 to 2015 for 23 crop classes.
