In Africa, agriculture, particularly crop production, is a vital livelihood practice for women, who provide a larger proportion of the labour force. However, the high reliance on rain-fed agriculture, coupled with other socio-economic constraints, exposes female farmers to climatic risks. This paper investigates the participation of women in crop production, key challenges and their coping strategies for climatic disturbances.

Industrial processes typically produce large wastewater volumes, which, if left untreated, greatly affect receiving ecosystems. However, wastewater treatment can be costly and energy-intensive, with the developing world particularly struggling with wastewater management. As such, simple and cost-effective solutions are urgently required with the passive (no energy or reagents) co-treatment of different wastewater matrices holding great promise.

The permeable reactive barrier has been deemed as the most prudent and pragmatic way to passively manage and remediate acid mine drainage (AMD). Herein, insights into mechanisms governing the removal of inorganic contaminants from AMD using a permeable reactive barrier (PRB), i.e.

Article Synopsis
  • This paper explores the use of pervious concrete as a potential solution for treating acid mine drainage (AMD) from gold and coal mines.
  • The study demonstrated impressive removal efficiencies for various metals (like Al, Fe, and Ni) from AMD, achieving rates between 75% to 99% across different samples.
  • The effectiveness of pervious concrete is linked to the formation of gypsum and metal hydroxides, which help reduce acidity and remove metals from contaminated water.
