Sustainable agriculture is crucial to ensuring food and nutritional security and improving livelihoods of millions across Africa. However, agricultural production is constrained by native and invasive pests. Indiscriminate insecticide use is often the first line of action to manage these pests, harming human and animal health, and impacting biodiversity. Thus, shifting to more ecologically sustainable alternatives is key to biodiversity conservation and sustainable agriculture. Biological control is a core component of integrated pest management strategies, and natural enemies, like parasitoid wasps, are considered one of the most environmentally sustainable means of managing pests. However, the Anthropocene plays a significant role in the success and sustainability of this approach. Therefore, here, we provide a look at the influence of anthropological activities, the scope of the application of parasitoids as biocontrol agents of invasive pests, and the current trends in parasitoid utilization in Africa.

Heavy metals released from metallic sulfidic tailings pose significant environmental threats by contaminating surface and groundwater in mining areas. Sustainable rehabilitation methods are essential to remove or stabilize these metals, improving the quality of acid mine drainage and minimizing pollution. This study examines the adsorption capacity of zinc ions (Zn) by different iron-silicate mineral groups under natural weathering and bacteria-regulated weathered conditions.

Poor management of nitrogen (N) can lead to serious environmental problems, such as air and water pollution. The accurate identification of priority control areas and emission sources is critical for making effective decisions regarding sustainable N management. This study aimed to identify hotspots for N losses and quantitatively analyze the relative contributions of different emission sources in the Huang-Huai-Hai Basin at the county scale.

In this study, physicochemical and structural properties of gelatin-zein blending films and bilayer films prepared through blending and layer-by-layer self-assembly method under TGase crosslinking were systematically compared. The ratios of gelatin to zein examined were 2:1, 1:1, and 1:2. Results showed that the tensile strength of both blending films and bilayer films was the highest when the ratio of gelatin to zein was 2:1, which was 4.

Tannic acid (TA) has attracted the attention of researchers as a promising organic ligand capable of forming metal-organic coordination networks with various metal ions at interfaces to impact surface properties. In this study, we innovatively reported a self-assembly method for surface decoration by depositing TA/Fe coatings on the surface of desalted duck egg white nanoparticles (DEWN), further studying the oil/water interfacial properties of the modified particles. The results showed that the ratio and concentration of TA to Fe could modulate interfacial properties.

Silver nanoparticles (AgNPs) exhibit broad-spectrum antibacterial activity and serve as effective antimicrobial agents against antibiotic-resistant bacteria. In this study, agricultural waste corn straw was used as the raw material to obtain cellulose nanocrystal (CNC) through enzymatic hydrolysis. The hydrolysate was employed as reducing agents to synthesize CNC-AgNPs.
