Summary: The study found that late planting with middle- to late-maturing potato cultivars could increase rainfed potato yield in North China. Along a 'N-S' transect, later planting with early-maturing cultivars is recommended for high yield and yield stability, while a 'W-E' transect should opt for later planting with late-maturing cultivars. The growth period and growing season precipitation were key factors influencing the variation in potato yield stability.

Summary: Cultivar and sowing date selection have significant effects on the yield and quality of maize. High temperature has a negative impact on yield, while accumulated temperature and solar radiation have positive effects. Cloudy and rainy weather during flowering reduces kernel number, but delayed sowing can mitigate this negative effect. However, delayed sowing also increases the risk of early senescence and frost.

Summary: Drought and heat stress are major limiting factors for crop production. Their simultaneous impact during sensitive growth phases could be more harmful. The study investigated the combined effects of drought and heat stress on wheat grain yield in different climates across Iran from 1980 to 2016, using different management practices. Historical trends showed an increase in grain yield in cold regions and a decrease in mild and hot regions. Long-term simulations suggested that drought alone could lead to a grain yield of 3.3 t ha(-1), but the addition of heat stress further reduced it to 2.9 t ha(-1). Optimal combinations of sowing date, cultivar, and initial soil water could mitigate the long-term impacts of drought and heat stress.

Summary: The study found that, under future climate conditions, potential yield and rain-fed yield losses of summer maize can be reduced with appropriate measures, while the yield loss of spring maize is smaller. Changing sowing date and planting density has a greater impact on spring maize yield, and the influence weakens as climate change intensifies. Therefore, it is necessary to investigate other adaptation measures to cope with climate change in the Guanzhong Plain of China.

Summary: The study analyzed the spatiotemporal changes in maize phenology in China from 1981 to 2018 and found that the trends in maize phenology were mainly influenced by rising minimum temperature, followed by maximum temperature, with the least impact from mean temperature. The study also highlighted that maize phenology is more sensitive to night-time warming than daytime warming, and the impact of cultivar shifts on maize phenology outweighs that of climate change.

Summary: The frequency and extent of wildfires in the Arctic have been increasing due to climate change. In this study, researchers conducted experiments in West Greenland to investigate the long-term impacts of climate warming on post-fire carbon dioxide exchange in arctic tundra ecosystems. They found that fire increased soil organic phosphorus concentrations and burned areas remained a net CO2 source five years after the fire. However, with four to five years of summer warming, the burned areas turned into a net CO2 sink.

Summary: This study investigates the impacts of water and heat stress on carbon uptake in China and explores the driving mechanisms of droughts using a machine learning model. The results show that droughts are mostly driven by atmospheric dryness, with precipitation, relative humidity, and temperature playing dominant roles. Water and heat stress have negative impacts on carbon assimilation, and drought occurrence is projected to increase significantly in the future. Improving ecosystem resilience to climate warming is crucial in mitigating the negative effects of droughts on carbon uptake.

Summary: This study proposes a method to partition evapotranspiration (ET) into its components in agroforestry systems. The method is based on water-carbon coupling theory and flux conservation hypothesis. The results show that the partitioned components agree well with measurements from other sensors. The study also finds that atmospheric evaporation demand and vegetation factors greatly influence the components of ET, and increased tree leaf area limits understory grass transpiration.

Summary: With the rapid increase of urbanization, evapotranspiration (ET) in urban forests has become increasingly important in urban hydrology and climate. However, there is still a large uncertainty regarding the factors that regulate ET in urban areas. This study investigates the temporal variations of ET in an urban forest park in Beijing using the eddy-covariance technique. The results show that daily ET is close to zero during winter but reaches 3-6 mm day-1 in summer. Daily ET increases with vapor pressure deficit (VPD) and soil water content (SWC). Monthly ET increases linearly with normalized difference vegetation index and shows a strong correlation with surface conductance (gs), while exhibiting saturated responses to increasing monthly precipitation (PPT). Annual ET ranges from 326 to 566 mm, and soil water replenishment through PPT from the previous year is responsible for the generally higher monthly ET in spring relative to PPT. Biotic factors and PPT seasonality play essential roles in regulating ET at different scales.

Summary: As climate change is expected to increase the intensity and frequency of extreme weather events, it is crucial to assess their impact on cropping systems and explore adaptation options. Process-based crop models (PBCMs) have improved in simulating the impacts of major extreme weather events, but still struggle to reproduce low crop yields under wet conditions. This article provides an overview of the yield-loss mechanisms of excessive rainfall in cereals and the associated modelling approaches, aiming to guide improvements in PBCMs.

Summary: Understanding the impact of climate on litterfall production is crucial for simulating nutrient cycling in forest ecosystems. This study analyzed a 14-year litterfall dataset from two subtropical forests in South China and found that litterfall was mainly influenced by wind speed during the wet season and by temperature during the dry season. These findings have potential significance in improving our understanding of carbon and nutrient cycling in subtropical forest ecosystems under climate change conditions.

Summary: Solar-induced chlorophyll fluorescence (SIF) has the potential to estimate gross primary production (GPP), but the quantitative relationship between them is not constant. In this study, a mechanistic model for SIF-based GPP estimation in evergreen needle forests (ENF) was developed, considering the seasonal variation in a key parameter of the model. The GPP estimates from this model were more accurate compared to other benchmark models, especially in extreme conditions.

Summary: Sustainable rice farming practices are urgently needed to meet increasing food demand, cope with water scarcity, and mitigate climate change. Traditional farming methods that prioritize a single objective have proven to be insufficient, while simultaneously optimizing multiple competing objectives remains less explored. This study optimized farm management to increase rice yield, reduce irrigation water consumption, and tackle the dilemma of reducing GHG emissions. The results suggest that the optimized management can maintain or even increase crop yield, while reducing water demand and GHG emissions by more than 50%.
