Summary: The study found that food consumption per capita in the Qinghai-Tibet Plateau has remained stable at a well-off level since 2010, corresponding to the physical geographic and climatic environment. The conflict between food security and ecosystem conservation can be managed without sacrificing nature, as total grain consumption has been stable since 2010 and agricultural conditions in the QTP have improved.

Summary: To examine the impact of climate change and population growth on wheat production in China, three crop models and three global climate models were utilized. The results showed that climate change would increase total wheat production, but population change would partially offset the benefits. The study also revealed that the per capita wheat production varied across different subregions in China. The findings emphasize the importance of further research to understand the implications of climate change and population growth on global food production and to develop robust policies for enhancing food security.

Summary: The Adapting Agriculture to Climate Change Project aimed to enhance the diversity and accessibility of crop wild relatives through seed collecting expeditions. A total of 4587 unique seed samples from at least 355 CWR taxa were collected, conserved, and made available through the Multilateral System of the Plant Treaty. Collections were made for all 28 targeted crops, with potato and eggplant being the most collected genepools. Several of the newly collected samples have already been utilized in pre-breeding programs to adapt crops to future challenges.

Summary: This article investigates how multiple agents can learn to coordinate in order to achieve efficient exploration in reinforcement learning. The proposed feudal latent-space exploration (FLE) tackles the problem of exponentially increasing difficulty in independent exploration of the joint action space as the number of agents increases. Experimental results demonstrate that FLE outperforms baseline MARL approaches that use independent exploration strategy in terms of mean rewards, efficiency, and the expressiveness of coordination policies.

Summary: This paper studies the coordinated dynamic task allocation (CDTA) problem for heterogeneous unmanned aerial vehicles (UAVs) in the presence of environment uncertainty. A CDTA strategy for heterogeneous UAVs is proposed through the proposer-responser mechanism and prioritized experience replay. The CDTA algorithm considers the uncertainty of dynamic tasks and has high scalability, effectively reducing the burden of online calculation and increasing the speed of online operation. Experimental results prove the effectiveness of the proposed algorithm, with scalability verified within 10-180 UAVs through comparison simulations with game theory-based and reinforcement learning-based methods.

Summary: The soil water characteristic curve (SWCC) is a key parameter for simulating soil water movement and solute transport, and it exhibits significant spatial variability. This study developed a one-parameter model based on the Gardner model to describe the SWCC and analyzed its spatial variability using multifractal and joint multifractal methods. The results showed that parameter B in the one-parameter model had moderate spatial variation and was influenced by different soil layers and scales.

Summary: This study investigated the effects of pyrolysis temperature and aging treatment on the adsorption performance of coffee grounds biochar (CGB) for Cd2+ and Zn2+. The results showed that the adsorption performance of fresh CGB increased with increasing pyrolysis temperature, while the adsorption performance of aged CGB peaked at medium pyrolysis temperature and decreased at higher temperatures. The XRD results indicated that the graphitization degree of CGB increased with pyrolysis temperature, leading to improved environmental stability. EDS and FTIR results suggested that ion-exchange and complexation played a dominant role in the adsorption processes, and the aging treatment improved the selectivity for Cd2+.

Summary: A two-year field study was conducted in a seasonally frozen area of northern China to investigate the influence of freeze-thaw cycles on soil salt migration. The results showed that biochar and corn stover could regulate soil pore structure and enhance snowmelt water infiltration, leading to increased soil moisture content. Biochar with abundant functional groups increased cation exchange capacity and promoted salt ion migration, while corn stover acted as a barrier to hinder salt return. Among all the treatments, the combined treatment had the lowest synergistic transport ability of soil salt and water.

Summary: In recent years, the synthesis of artificial humic substances (A-HS) through alkaline hydrothermal processing of waste biomass has been described. These A-HS have shown to have various effects on soil, including water and mineral binding, soil structure alteration, inhibition of fertilizer mineralization, and promotion of plant growth. The observed macroscopic effects have been attributed to the stimulation of the microbiome, which plays a key role in this anthropogenic soil system. By understanding this complex system, it is possible to address global issues such as soil fertility, nutrition for a growing population, and climate change.

Summary: In this study, the effects of freeze-thaw cycles, straw and biochar applications on soil hydrothermal parameters were investigated. The results showed that freeze-thaw cycles affected soil porosity and destroyed soil aggregates, while straw and biochar applications increased total soil porosity and enhanced soil aggregate stability. The applications of straw and biochar also increased soil saturated hydraulic conductivity, with biochar showing a stronger improvement effect. A 1% biochar application was recommended as the optimal soil amendment.
