Urban and peri-urban agriculture is considered a strategy that can bring multiple benefits and help to build resilient urban food systems at the city region level and enhance the climate resilience of vulnerable residents. Cities, as major emitters of greenhouse gas (GHG), are not only contributing to climate change but are also directly and indirectly impacted by it. Key issues include rising temperatures, increasing rainfall, flooding, and urban food insecurity. Rapid urban growth will only increase the number of highly vulnerable urban communities, with the urban poor being most at risk.

Odiney Alvarez‐Campos, Gregory K. Evanylo · Journal of Environmental Quality · Global

The impacts of exceptional quality (EQ) biosolids and inorganic fertilizer applied for rehabilitating anthropogenic soils on potential nitrogen (N) and phosphorus (P) water quality impairment risk were compared. After two years, reclamation rates of biosolids resulted in soil P saturation ratios greater than the recommended 30% but lower than the 65% limit. While nitrate N (NO3–N) posed the greatest nutrient leaching risk, lysimeter-collected mass loading of NO3–N from reclamation rates was not greater than for the inorganic fertilizer.

A hydroponic experiment in Indonesia tested the effect of plant growth regulators on water spinach (kangkung, Ipomoea aquatica) yield. Treatments included a control (AB-Mix), IAA (indole acetic acid) at 0.5 ppm, BAP (benzyl adenine purine) at 0.5 and 1.0 ppm, and combined IAA/BAP at 0.5/1.0 ppm, measuring leaf number, plant height, antioxidant content and water content. Morphological growth was most optimal under 0.5 ppm IAA, while 1.0 ppm BAP produced the shortest average plant height, fewest leaves and shortest root length. Chlorophyll testing showed 0.5 ppm IAA had the highest total chlorophyll content, averaging 9.55 μg/ml, and the authors conclude 0.5 ppm IAA had the most positive effect among the treatments tested.
