“…For instance, rural Ugandan households frequently depend on woody materials for fuel, which could be potentially used as feedstock for biochar production. Using unused residues of cereals and legume crops such as maize, sorghum, millet and groundnut as feedstock for biochar production may present a viable outcome (Roobroeck et al, 2019).…”

In dit rapport onderzoeken we mogelijkheden voor de ondersteuning van de biologische landbouwsector in Oeganda, door middel van literatuuronderzoek en interviews. We documenteren bestaande initiatieven in de biologische landbouw in Oeganda, van de productie van biopesticiden en biologische meststoffen tot overkoepelende organisaties en platforms, en we geven inzicht in mogelijke aanvullende praktijken voor verder onderzoek en verspreiding. Het rapport geeft een overzicht van de belangrijkste uitdagingen en kansen, en biedt aanbevelingen zoals verbeterde kennisvoorziening voor boeren, identificatie van business cases, verbeterde regelgeving en kwaliteitscontrole, systematische studies naar de effectiviteit en (economische) haalbaarheid van biologische landbouwpraktijken, en meer consumentenbewustzijn om de vraag naar veilig geproduceerd voedsel te stimuleren.In this report we explore opportunities to support the organic agriculture sector in Uganda, gathered from literature review and interviews. We document existing initiatives in organic agriculture in Uganda, from the production of biopesticides and biofertilisers to umbrella organisations and platforms, and provide insights into potential avenues for further research and dissemination. The report synthesises main challenges and opportunities, and offers recommendations including enhanced knowledge provision for farmers, identification of business cases for organic agriculture, enhanced regulation and quality control, systematic studies documenting effectiveness and (economic) feasibility of organic agriculture practices, and increased consumer awareness to drive the demand for safely produced food.

“…Biochar: Implications for food and yield, nutrients and minerals, and general soil conditions are the primarily discussed side effects of biochar soil amendment. Articles mentioning impacts on food and yield are predominantly positive (n=20) compared to negative (n=5) due to observed biochar-related yield increases for various crops 54,81 . Described implications for nutrients and minerals appear to be both positive and negative, with many effects for which desirability is unclear.…”

Carbon dioxide removal (CDR) is key to climate change mitigation, yet implications of its deployment remain unclear. Recent exponential growth in literature is rapidly filling this gap but makes the synthesis of the evidence on CDR side effects increasingly challenging. We address this issue by mapping this literature and proposing a taxonomy to synthesize and compare evidence on CDR side effects. The expansive evidence warrants the use of machine learning to systematically select relevant research and provide an inventory of nearly 400 side effects and challenges. We find rich evidence in Europe but little information for Africa, South America, and Oceania, where large-scale CDR is nevertheless projected. There is a predominance of articles discussing negative effects compared to positive ones. Starting from the limitations of our analysis and literature gaps, we provide entry points for future studies that can build on our literature-based taxonomy.
