This study analyzed the inverse relationship between economic efficiency and social and environmental justice in the use of pesticides. The use of pesticides tends to improve economic efficiency by increasing agricultural productivity, however, it can also increase social and environmental injustice. This inverse relationship was inferred since the economic efficiency gained with the use of pesticides is [usually] associated with some kind of social and environmental injustice. This study also analyzed the impact of regulatory measures to control the use and handling of pesticides. Strict pesticide regulations could jeopardize agricultural competitiveness, especially in some small rural communities; therefore, the cost-benefit results of pesticides regulations could be negative and detrimental comparing to potential pesticide effects on human health and the environment. This study also concluded that some regulatory control is needed; however, it should be well designed and managed.

In light of the Chinese government's dual carbon goals, achieving cleaner production activities has become a central focus, with regional environmental collaborative governance, including the management of agricultural carbon reduction, emerging as a mainstream approach. This study examines 268 prefecture-level cities in China, measuring the carbon emission efficiency of city agriculture from 2001 to 2022. By integrating social network analysis and a modified gravity model, the study reveals the characteristics of the spatial association network of city agricultural carbon emission efficiency in China.

The advent of smart cities has brought about a paradigm shift in urban management and citizen engagement. By leveraging technological advancements, cities are now able to collect and analyze extensive data to optimize service delivery, allocate resources efficiently, and enhance the overall well-being of residents. However, as cities become increasingly interconnected and data-dependent, concerns related to data privacy and security, as well as citizen participation and representation, have surfaced.

This study aims to reduce engine emissions while maintaining engine performance and providing a sustainable fuel source for long-term use. It introduces a novel approach by combining pine oil (PO) and lemon grass oil (LGO) with diesel fuel in a specific ratio (10% PO + 10% LGO + 80% Diesel). This work is innovative in that it employs these two distinct low-viscosity biofuel blends in conjunction with diesel fuel in an agricultural engine, resulting in reduced carbon footprints in the tailpipe.

Increasing antimony (Sb) pollution has become a global concern, but there is still a lack of economically efficient adsorbents for its remediation. In this study, a novel remediation material was developed by precipitating TiO onto waste herb-residue biochar (named TBC). The effectiveness and adsorption mechanisms of the material for Sb(III) removal were investigated through adsorption experiments, and the enhancement pathway of traditional herb decoction on the effectiveness of modified biochar was analyzed.

A novel air-to-liquid mass transfer system using wetted rotating membranes was designed to enhance air-to-liquid carbon dioxide (CO) mass transfer efficiency. Traditional methods, such as sparging, are energy-intensive, but the rotating membrane reduces energy demands by optimising membrane wetting via rotational motion. Experimental tests were conducted using a small-scale system with a membrane width of 0.
