Assessing the viability of hydroponics for low‐income farmers in South Africa's urban agriculture sector: An urban political ecology perspective

open access: yesUrban Agriculture &Regional Food Systems, Volume 11, Issue 1, 2026.
Abstract Urban agriculture in densely populated areas is significantly constrained by space, leading to interest in vertical farming solutions like hydroponics. This study evaluates hydroponics’ viability in Cape Town's low‐income urban areas as a useful supplement to most research, which focuses on cities in the Global North.

Spreading of recently introduced North American sand dropseed (Sporobolus cryptandrus) threatens European native dry grassland arthropods

open access: yesInsect Conservation and Diversity, Volume 19, Issue 1, Page 131-145, January 2026.
The effects of sand dropseed (Sporobolus cryptandrus) invasion on arthropods depended on its density and varied between habitat types and arthropod groups. Vegetation‐dwelling, primarily herbivorous orthopterans and true bugs were most sensitive to invasion. Sand dropseed negatively affected the arthropod species of high natural value.
