2023Mahbuba Ferdous · Asian Journal of Advances in Agricultural Research · Australia (Armidale)
This case study investigated non-chemical weed management strategies in a small-scale vegetable garden in Armidale, Australia, through observation and an in-depth, unstructured interview with the garden's convener. Growers primarily used mechanical and cultural methods, including mulching, hand weeding, tillage, and grazing, to manage weed infestation. While mulching with wood chips and hand weeding were considered more effective in minimizing weed competition during critical crop development periods, they could not reach a satisfactory level. Further improvements by integrating several approaches simultaneously are needed for more effective and economical weed control.

2022Angelica Mendoza Beltrán, Kelzy Jepsen, Martí Rufí-Salís, Sergi Ventura, Cristina Madrid‐López, Gara Villalba · The Science of The Total Environment · Spain (Barcelona)
This study mapped N2O emissions from peri-urban agriculture in the Metropolitan Area of Barcelona (AMB), Spain. Researchers spatially distributed factors like crop type, fertilizer use, and irrigation, creating N2O emission maps using crop-specific and Tier 1 IPCC emission factors (EFs). The study found that Tier 1 IPCC EFs estimated 15% more emissions (7718 kg N2O-N year−1) than crop-specific EFs (6533 kg N2O-N year−1) for the entire AMB, indicating higher emissions for rainfed crops with Tier 1 EFs and for irrigated horticultural crops with crop-specific EFs. The mapping helps evaluate spatial variability of key factors but carries uncertainties due to downscaling regional data.
