Summary: This study investigated the interactive effects of nitrogen (N) fertilisation and elevated atmospheric CO2 on biomass, yield and water use of two wheat cultivars. The results showed that elevated CO2 stimulated leaf area and biomass, reduced stomatal conductance, and increased water use efficiency. Supplementation of nitrogen increased the yield of one cultivar but decreased the yield of another. Therefore, considering the unique nitrogen use efficiency and responsiveness of wheat cultivars is important for optimizing the benefits from the "CO2 fertilisation effect" through breeding.

Summary: The availability of high-resolution and long-term geo-information is crucial for developing strategies to adapt to climate change in agricultural cropping areas. In this study, we evaluated the effectiveness of creating yield indicators using a combination of yield mapping data, a precision agriculture tool, and satellite imagery. The annual models showed the best predictive performance, and they could be extrapolated with reasonable spatial precision in a regional analysis but not in a state-wide analysis.

Summary: Lake surface water temperature is highly sensitive to climate change and is found to be warming globally. The warming rate of global lakes varies by region, with dryland lakes experiencing more significant warming compared to semi-humid and humid regions. Air temperature is identified as the main driving force for lake warming. Future projections indicate that lake surface water temperature will continue to rise, especially in dryland areas.

Summary: Climate change has adverse effects on global crop yields, including heat waves, water stress, and extreme weather events. This study focuses on the interannual variability of temperature, precipitation, and soil moisture during the flowering period of wheat, maize, and rapeseed in Europe. The results show significant increases in variability, particularly for winter wheat, while rapeseed flowering is less affected due to its early timing and northern cultivation areas. The study highlights the importance of diversifying risk in agricultural adaptation to ensure crop yield stability in a warming climate.

Summary: Global drylands are experiencing a boom in the development of centralized photovoltaics to address climate change and energy transformation. In this study, the impact of solar PV deployment and climate change on vegetation in a large-scale dryland PV plant was quantified. The results showed that vegetation has increased gradually, with the rate of recovery doubling during the PV expansion period. Climate change was found to be the main driver of increased vegetation, followed by the expansion of solar PV infrastructures. Vegetation inside PV arrays grew faster due to improved rainwater utilization and reduced sunlight impact.

Summary: Climate-smart agriculture (CSA) is recommended by the United Nations as a method to help farmers build crop resilience against climate-related yield uncertainty. This study uses game-theoretical models to analyze the impact of CSA on the competitive agricultural marketplace. The results show that CSA adoption is preferable for farmers when the climate-related yield uncertainty is high, but unprofitable when the uncertainty is low. The study also examines how climate-related yield uncertainty and segmented agrimarket selection affect yield competition.

Summary: This study utilized NDVI time series to analyze planting and harvesting dates for corn and soybean in Kentucky, finding delays in planting and harvesting dates for both crops, as well as an increase in growing season length for corn and a decrease for soybean. Sensitivity analysis showed planting dates were more affected by early season temperature, while harvesting dates were correlated with temperature throughout the entire growing season. Increased summer precipitation was found to be related to delayed corn harvesting dates in Kentucky. Additionally, delayed corn harvesting dates and extended growing season length were correlated with increased corn yield.

Summary: The increase in atmospheric carbon dioxide concentration affects root growth in grain crops unevenly, with differences in responses between depths and genotypes. While root growth in the topsoil is stimulated by elevated CO2 levels, it is not strongly correlated with yield response. Conversely, root growth below 30 cm depth shows a stronger correlation with increased yield response to elevated CO2 levels.

Summary: Heat stress under well-watered conditions does not have a detrimental effect on leaf photosynthesis or yield. However, it does modify the response of photosynthesis and yield to elevated CO2 levels in wheat. Elevated CO2 improves photosynthesis in both control and heat stressed wheat, but improves biomass and yield only in control plants. Heat stress prevents a yield response to elevated CO2.

Summary: This study investigated the effects of different organic amendments on wheat grown in alkaline dispersive subsoils. The results showed that in the short term, organic amendments improved soil properties and increased wheat yield, but did not provide significant nutritional benefits compared to inorganic fertilizers. Further long-term studies are needed to understand the legacy effects of organic amendments on soil structure and nutrient contribution in alkaline dispersive subsoils.

Summary: Summer cover crops can provide biomass, nitrogen fixation, and biopores in Mediterranean cropping systems, but they may also reduce water availability for the following cash crops. Limited research exists on the rooting patterns and water use of summer cover crops in Mediterranean-type environments. This study evaluated legume (sunn hemp, cowpea, mung bean, lablab), non-legume broadleaf (buckwheat, radish), and cereal (millet) cover crops for their root distribution, depth, diameter, water use, and biomass production. Millet had the highest biomass and water use efficiency, while legumes exhibited greater subsoil water use. Dual species mixes with millet or cowpea showed increased biomass production and deeper rooting. Results indicate that millet may be preferred for minimal water use, while legumes may benefit in wetter seasons for subsoil drying and biopore creation. Overall, cover crops reduced soil water storage compared to fallow, potentially impacting cash crop yield.
