Summary: This paper discusses an old soils report produced using an agronomical approach, focusing on parts of Spain's Huesca and Zaragoza provinces. Data was collected by the Spanish Ministry of Agriculture from 1975 to 1978 through the National Institute for Agrarian Reform and Development, in order to evaluate the potential of lands for irrigated agriculture. The document provides a unique snapshot of soils and agriculture in the 1970s, serving as a baseline for multitemporal comparisons.

Summary: The expansion of irrigated croplands has significantly boosted global agricultural productivity throughout the 20th century. However, limited progress has been made in sub-Saharan Africa due to under-delivery of irrigation schemes and policies. This study focuses on the Senegal River Valley, mapping the distribution of croplands under active irrigation between 1986 and 2020. The research reveals two distinct periods of irrigation development, with a stagnant phase until 2008 followed by a boom phase.

Summary: This study quantified the impacts of climate change and agricultural management adaptation on irrigated agriculture in the Indus basin. The results show that by the 2030s, improved nutrient availability and constrained irrigation can achieve sustainable and increased agricultural production. However, by the 2080s, the productivity will strongly depend on worldwide climate-change mitigation efforts.

Summary: This study aims to define a rapid procedure to calculate geometric parameters of the canopy of hazelnut trees using UAV images and remote sensing technologies, providing scientific basis for hazelnut orchard management. By analyzing the NDVI and CHM values derived from the UAV images, the canopy area and height can be accurately calculated. Applying this technology to hazelnut orchards can improve resource use efficiency and crop quality.

Summary: The study found that irrigated agriculture can increase soil organic carbon (SOC) stocks, with the greatest increase observed in semi-arid regions at shallow soil depths. The impact of irrigation on SOC varies by climate and soil texture, with sprinkler irrigated sites showing an increase in SOC while drip irrigated sites showing a decrease.

Summary: Understanding the link between rainy season onset and crops sowing dates is crucial for high-yield agricultural management in multiple cropping systems. This study in Western Bahia, Brazil, used crop calendars derived from remote sensing products to investigate the relationship between sowing dates and the onset of the rainy season. The results showed that rainfed sowing dates are strongly correlated to rainy season onset and are particularly affected in years with delayed rains, while irrigated sowing dates occur much earlier and are not correlated to rainy season onset. This indicates that irrigated farms have adapted their sowing operations to be more intensive and efficient in water use during the rainy season.

Summary: This study focuses on monitoring seasonal irrigated cropland in the Berambadi watershed in southern India using multiple optical satellite images. By calculating seasonal cumulative normalized difference vegetation index and applying support vector machine classification, the study successfully classified irrigated cropland areas. Validation results demonstrate the relevance of multi-source optical satellite data for quantifying areas under groundwater irrigation in tropical regions.

Summary: The application of excessive nitrogen fertilisers can lead to nitrate contamination in groundwater, which can impact surface water quality. This study in the Emerald Irrigation Area, Australia, investigated the occurrence and controls of denitrification in nitrate-rich aquifers. The results showed that denitrification primarily occurs in anaerobic zones and beneath leaking irrigation channels, leading to significant nitrate reduction. Understanding regional and local hydrogeological processes is crucial for assessing the impacts of nitrate contamination on adjacent ecosystems.

Summary: The objective of this research is to detect seasonal agricultural land use and cropping pattern in the Mujib basin in Jordan. The study utilized high-resolution satellite images to classify the land use types and identify the cropping pattern within the basin. The results show the importance of considering agricultural land use in water consumption and management strategies.

Summary: The study found that irrigation agriculture may lead to environmental issues such as soil degradation and aquifer contamination, posing a threat to crop production. Nitrous oxide emissions in the irrigated areas accounted for up to 4.5% of applied nitrogen, with nitrate losses reaching about 18%. Water tables in the aquifers were observed to be dropping at rates ranging from 0.4 m to 1.5 m per year, depending on the location.

Summary: Vegetation monitoring using remote sensing time-series data has been effectively conducted for decades, with focus on drought detection. This study compares the use of eMODIS and eVIIRS for drought monitoring and vegetation anomaly detection, finding consistently high correlations and similar results between the two sources. The study proposes the suitability of VIIRS NDVI as a replacement for MODIS NDVI in future monitoring efforts.

Summary: Assessing temporal trends in vegetation greenness is crucial for understanding the responses of terrestrial ecosystems to climate and environmental changes. This study analyzed vegetation greenness trends in different natural land cover types across the conterminous United States using satellite data. Positive trends were observed in forests and grasslands, correlated with increasing temperature, while negative trends were found in shrublands and grasslands, associated with increasing temperature and decreasing precipitation.

Summary: Studies have shown that California has experienced frequent drought events, hotter temperatures, and other disruptions to the climate system, resulting in significant tree cover loss. The increasing trend of tree cover loss is primarily driven by climate stress and wildfires. These findings suggest that future hotter and drier climate conditions may further endanger California's ecosystem.

Summary: The high variability of forage production in semiarid grasslands poses challenges for livestock producers in decision-making. In this study, a forage production model called ForageAhead was used to estimate annual forage production using environmental and seasonal climate variables. By incorporating summer climate scenarios based on historical data, the model can provide a range of possible forage production scenarios by the end of May. The results showed that using five percentile categories for summer precipitation and temperature can accurately predict the interannual variability of forage production.

Summary: This study used sample-based estimates and complete coverage land-cover maps to analyze and describe the patterns of annual land-cover change in the contiguous United States (CONUS) from 1985 to 2016. The results showed that while most of the land cover remained stable over the period, there were significant changes in natural resource cycles, urbanization, and surface-water dynamics. The study also revealed a reduction in the rate of urban expansion after 2006, new growth in cropland after 2007, a net decline in cropland since 1985, and two periods of net tree cover loss.

Summary: The United States has a mature and stable land use and land cover system, with changes in irrigation land use occurring frequently due to various factors. Through consistent methodology, irrigation dynamics were mapped across the lower 48 states over four map eras, showing surprising regional variability in irrigated area changes. Drivers for irrigation dynamics include climate fluctuations, crop demands, government policies, and economic incentives, with accuracy of the dataset ranging from 70% to 95% depending on the region.
