The increasing food scarcity necessitates sustainable agriculture achieved through automation to meet the growing demand. Integrating the Internet of Things (IoT) and Wireless Sensor Networks (WSNs) is crucial in enhancing food production across various agricultural domains, encompassing irrigation, soil moisture monitoring, fertilizer optimization and control, early-stage pest and crop disease management, and energy conservation. Wireless application protocols such as ZigBee, WiFi, SigFox, and LoRaWAN are commonly employed to collect real-time data for monitoring purposes. Embracing advanced technology is imperative to ensure efficient annual production. Therefore, this study emphasizes a comprehensive, futureoriented approach, delving into IoT-WSNs, wireless network protocols, and their applications in agriculture since 2019. It thoroughly discusses the overview of IoT and WSNs, encompassing their architectures and summarization of network protocols. Furthermore, the study addresses recent issues and challenges related to IoT-WSNs and proposes mitigation strategies. It provides clear recommendations for the future, emphasizing the integration of advanced technology aiming to contribute to the future development of smart agriculture systems.

“…Meeting the nutrient consumption demands of the urban population necessitates an increase in the supply of food and other products containing N or P, thereby accelerating the cycling of these nutrients [95][96][97]. Moreover, rapid urbanization in China has also resulted in a severe labor shortage in rural communities, leading to the excessive use of fertilizers and pesticides to maintain or increase grain yields [98,99]. Studies have shown that P cycling in China has been artificially intensified, primarily through fertilization, resulting in a three-fold increase in P losses to rivers and lakes [94,100].…”

Socioeconomic development often leads to environmental pollution and degradation initially while, beyond a certain point, there is the potential for improvements in environmental quality. In this study, we conducted a comprehensive review of published literature and national data to investigate changes in nutrient concentrations and limitations in Poyang Lake from 1978 to 2021. Our objective was to examine the relationships between these changes and the process of socioeconomic development in the watershed. The findings revealed a rapid socioeconomic development of the Poyang Lake Watershed, showing significant changes in various indexes. For example, population, Gross Domestic Product (GDP), urbanization, grain and meat productions, sewage amount and treatment rate, and forest coverage in the watershed showed increasing trends with different fitting curves, each following distinct fitting curves such as exponential, binary, and linear models. Concurrently, the concentrations of total nitrogen (TN) and total phosphorus (TP) in Poyang Lake exhibited a linear increase over the years, surpassing eutrophication thresholds since the early 1980s. However, TN and TP have shown a decreasing trend in recent years. Notably, the lake displayed co-limitation by N and P, with TN primarily driving the N:P ratio. TN and TP showed a significant “∩” shape with the increase in GDP and urbanization, while they increased with the population. TN:TP showed an increasing pattern with GDP and urbanization but a “U” shape with the population. This research contributes significant insights into the long-term changes in nutrient concentrations, shifts in nutrient limitations, and their associations with socioeconomic development. The findings highlight the need for a balanced and strategic approach to appropriately manage both nutrients for effective eutrophication mitigation.

“…Rural settlement consolidation (RSC) is a process of adjusting the land allocation within rural settlements through economic, technical, and policy means to coordinate the human-land relationship in rural areas [8]. In addition to reconfiguring land parcels to make fragmented rural settlements concentrated and orderly, RSC simultaneously improves rural service facilities and infrastructure [9,10], optimizes rural landscapes [11], and creates large-scale production spaces for agriculture [12,13]. Land consolidation is an effective tool to support the sustainable development of rural settlements [14].…”

Rural settlement consolidation (RSC) is an important tool for improving rural habitat environments, and the potential evaluation of RSC is the premise for rural settlement planning. This paper identified the potential sources of RSC in different reconstruction modes and built an influencing factor system for RSC. We analyzed the spatial differentiation patterns of the theoretical potential and the realistic potential, and we identified the factors influencing the potential realization based on an empirical investigation in China. Influenced by multiple constraints, the potential transition from theoretical to realistic was spatially differentiated and showed a spatial agglomeration at the village level. Rural depopulation had a direct impact on the theoretical potential of RSC, while the distance to the downtown, rural population, per capita GDP, and production and living conditions played an important role in the realistic potential. Particularly, rural settlement basic conditions, rural population, and arable land resources profoundly affected farmer exit willingness and the potential transition from theoretical to realistic. Four optimization paths for rural settlement reconstruction linking to land use policies were proposed, which could provide valuable information for rural settlement planning in socioeconomic transformation regions.
