Summary: A framework to quantify the impact of drought on sugarcane growth in different stages and regions in Guangxi has been proposed in this study. The drought tends to intensify in the sugarcane growing season, especially in Southwest Guangxi. The water demand of sugarcane shows an upward trend in most areas, with the highest requirement during the stem extension stage. Short-term drought events in August and September significantly affect sugarcane production. This method can be applied to other crops in different regions.

Summary: This study aims to predict the irrigation needs of corn crops in different regions of Ecuador, which is a fundamental food for the country's economy and other countries in the Andean area. Regression models based on Functional Data Analysis (FDA) are proposed to predict rainfall based on functional covariates such as temperature and wind speed. The models show high goodness of fit and practical utility. The study also demonstrates the application of FDA exploratory analysis and outlier detection techniques in rainfall prediction studies.

Summary: Meteorological factors and changes in crop area have significant impacts on agricultural water resources. This study analyzed the spatiotemporal variations of crop water requirements (CWR) and irrigation water requirements (IR) in the lower reaches of the Yellow River Basin. The results showed a decreasing trend in unit area CWR and IR, with the highest sensitivity to wind speed. Crop area change was found to be the major contributor to the variations in total volume of CWR and IR. These findings provide valuable insights for adaptive strategies in agricultural water management.

Summary: The study estimated the crop water requirement and irrigation water requirement of winter wheat in the middle reaches of the Yarlung Zangbo River and its two tributaries from 1981 to 2015, showing a significant decrease in CWR and IR, while effective precipitation increased annually. Factors such as wind speed and sunshine duration had a significant impact on CWR variations, with wind speed identified as the determining factor. Similarly, the CWR was found to be the main determining factor of IR variations.

Summary: Climate change is causing more frequent droughts, leading to water scarcity and affecting crop yields. Underground pumping systems can provide water for crops, but the energy required is expensive and harmful to the environment. Developing renewable energy sources to power water pumping systems is crucial for improving crop yields and reducing carbon emissions, especially in regions like northern Sudan that are more vulnerable to drought.

Summary: The study shows that different irrigation methods and levels significantly affect maize yield, water consumption, and economic benefits. In the study, drip irrigation at -30 kPa is recommended as a priority to replace border irrigation, as it can increase yield, reduce water usage, and achieve higher net profit.

Summary: This study explores the variation of crop irrigation water requirement (IWR) in the Yellow River Basin (YRB) and identifies the dominant meteorological factors influencing IWR for different crops. The results show that temperature is increasing while precipitation remains unchanged during the growing season. IWR for spring wheat, winter wheat, and spring maize is increasing, while summer maize shows a slight decrease. The findings highlight the need for effective water-saving measures to mitigate the adverse impact of climate change on agriculture.

Summary: Seed predation is crucial for reducing the abundance and spread of unwanted vegetation in agricultural ecosystems. Vertebrate and invertebrate seed predators play a key role in regulating the population growth of winter annual weeds like A. myosuroides in intensively managed agroecosystems. Protection of weed seed predators is essential for minimizing dependence on chemical and mechanical measures for weed management.

Summary: When modelling forest growth, it is important to consider the effects of climate change for accurate long-term predictions and forest management choices. However, commonly used mensurational forest growth models based on inventory data cannot account for climate change effects. To address this challenge, hybrid physiological/mensurational basal area growth and yield models were developed, which incorporate physiological response to climatic conditions and empirical relations. These models successfully reproduced observations and revealed the significant impact of climate change on forest productivity.

Summary: Jet stream variability plays an important role in vegetation activity in Europe, with correlations found between jet latitude anomalies and vegetation greenness anomalies. The strength and sign of these correlations depend on location and time of the year, and are mediated by temperature, soil moisture, and downward surface solar radiation. The link between jet latitude anomalies and vegetation greenness is specific to the climate zone, landclass, and subperiod within the growing season.

Summary: In order to understand the impact of climate change on crop yields, it is important to identify the most effective climatic indices for predicting yields. This study examines the relationship between precipitation, temperature, soil water availability, and crop yields for rainfed maize and soybeans in the USA from 1970 to 2010. The results show that soil water availability, as measured by the aridity index, is a better predictor of yields than precipitation and temperature. The study also found that there are non-monotonic responses, with yields maximized at intermediate levels of precipitation and temperature. These findings have important implications for future agricultural planning and suggest that climate change may reduce yields.

Summary: Plant responses to water stress affect water and carbon cycles and may have climate feedbacks, but characterizing these responses at the ecosystem level is uncertain. Quantifying ecosystem-level water use strategies is challenging due to difficulties in upscaling plant traits and disentangling environmental factors, limiting our understanding of global change in ecosystem dynamics and ecohydrological fluxes.

Summary: Grain yield data from 32 long-term experiments across Europe and North America suggest that increasing crop functional richness in rotations can support grain yields more than species diversity. Diversifying agriculture through crop rotation and increasing crop species diversity can reduce negative impacts on the environment and maintain yields. However, it is unclear how cereal yields change with crop rotation diversity and external nitrogen fertilization level over time, and which functional groups of crops provide the most yield benefit.

Summary: The decrease in stomatal conductance and increase in leaf area under elevated atmospheric CO2 concentration lead to a reduction in leaf-level transpiration rate while having little effect on canopy-level transpiration. Both models predict an increase in leaf and canopy-level CO2 assimilation, with amplified CO2 fertilization effects at the canopy level due to enhanced leaf area. The increase in vapour pressure deficit under warmer conditions is expected to decrease the sensitivity of gas exchange to atmospheric CO2 concentration in both models.

Summary: Models that predict forest development are crucial for sustainable forest management. This study developed and compared four species-specific models, and found that the compatible growth and yield models could be recommended, especially when data availability is limited. Additionally, the currently used Elfving model performed well in predicting basal area. Future research should focus on model development for heterogeneous forests.
