Title: Opportunities for promoting integrated action on air pollution and climate in Africa Authors: Toure, Evelyne N.; Nthusi, Victor Victor; Garland, Rebecca; Mbandi, Aderiana M.; Bainomugisha, Engineer; Hodoli, Collins G.; Doumbia, Madina; Mbiake, Robert; Klopper, Danitza; Ojeh, Vincent N.; Gatari, Michael Abstract: BACKGROUND AND AIM[|]The complex interactions between climate change and air quality mean that coordinated action can lead to better public health and improved societal outcomes. While the health impacts of climate change are varied, impacts from exposure to air pollution are well known. Air pollution and climate change are a deadly duo for Africa and must be tackled together.[¤]METHOD[|]The Climate and Clean Air Coalition (CCAC) developed, in 2022, an integrated assessment on air pollution and climate change in Africa to identify and assess priority measures that reduce emissions while maximizing the multiple benefits for health, ecosystems, climate, and food security. This scientifically led process was conducted in partnership UNEP Regional Office for Africa (ROA), the African Union Commission (AUC) and the Stockholm Environment Institute (SEI) and brought together academics, experts, and practitioners working across Africa to address the growing air pollution and associated climate threats while promoting capacity building and action to reduce air pollution and climate change.[¤]RESULTS[|]The Africa Integrated Assessment of Air Pollution and Climate Change (Africa Integrated Assessment) provides 37 measures which if implemented could provide a tailored package of solutions for clean air for the region which will link meaningfully to the Sustainable Development Goals (SDGs), the National Determined Contributions (NDCs) under the Paris agreement, and the Agenda 2063 for Africa. The 37 measures have been categorized according to key economic sectors: household, energy, transport, power generation, industry, agriculture, and waste management and would mitigate climate and air pollution impacts on human health, crop yield and vegetation.[¤]CONCLUSIONS[|]The assessment findings and recommendations will be presented at the conference during the ‘Stories of Policy Success: Real Examples of Inspiring Science-based Air Quality and Climate Action Around the World’ symposium. We have identified some national case studies that align air quality and climate action across sectors in Africa. Description: https://doi.org/10.1289/isee.2024.1762

Title: Storage and preservation of seed grain under enhanced hermetic conditions Authors: Home, P. G.; Shitanda, Douglas; Ndigithe, P. M. Abstract: Hermetic grain storage is a system where dry grain is stored under conditions of oxygen deficit. Any insects in the stored grain then suffocate themselves to death through depletion of any remaining oxygen and release of CO2 through respiratory metabolism. In this study, performance of hermetic storage was evaluated using maize grain. The grains were stored in plastic bags in quantities weighing 250 g each which were deliberately infested with weevils. Air was sucked from the plastic bags with a vacuum pump and the bags sealed air tight. In the 'enhanced' hermetic storage, smoke from insect repelling herbs (Lantana trifolia, Tagetes minuta and Ocimum suave) was introduced into the bags and then sealed. In other samples, dry leaves from the herbs were mixed with the grains before sealing. Each treatment was replicated six times. The extent of grain damage in terms of weight loss was monitored at intervals of two weeks. The grains stored in the enhanced hermetic conditions where smoke from the herbs had been introduced showed the least weight loss. The highest weight loss of the grain was observed in the conventional hermetic storage where only air was evacuated from the storage bags. Samples with smoke from Tagetes minuta were the best preserved amongst the smoke treatments. The results indicated the potential for the enhanced hermetic storage of grain utilizing locally available herbs with known insect repellent properties. The system if adopted can prevent excessive grain loss from insect infestation and minimize the use of environmentally harmful chemicals.

Title: Properties of Kenyan grown Mondia Whytei roots Authors: Shitanda, Douglas; Mukonyi, K.; Simiyu, L.; Mayunzu, O.; Shanda, R. Abstract: Mondia Whytei (Asclepiadaceae) is a tropical species widely used in African countries where it is found, both at subsistence and commercial level. The species is commonly found in remaining tropical rain forests. Solar dried roots were milled as peel and core separately. The taste for the whole root powder was found to be sweeter compared to that of the peel or core alone. Mondia root Juice was prepared through simple boiling of both dry and fresh roots. Six months storage of the juice showed no fungal infestation or loss of flavour. Mondia Whytei roots showed varied significant amounts of elements and minerals. The roots had very high concentration levels of potassium and calcium ranging between 81-491 mg/100 g and 139-530 mg/100 g respectively. Iron and zinc were in low concentrations of 0.027 mg/100 g and 1.36 mg/100 g respectively. Cadmium and Lead appeared in trace amounts. Crude protein was about 3 mg/100 g, vitamin β carotene ranged from 0.5-8.2 mg/100 g. Sugars mainly fructose ranged between 215-710 mg/100 g and glucose between 110-506 mg/100 g. Results obtained showed that the roots had high potential for use as a nutritive source and as an additive in human and animal foods.
