“…To estimate N 2 O emissions from manure management, a good knowledge of manure management systems in the country is required. This information has been obtained from IPCC as per the prevailing MMSs in Africa (IPCC 2006) and further verified from other literatures (Onweremadu et al 2007;Kalu 2015;Ogundiran et al 2015;Olusoji and Sunday 2016) as well as experts' opinion.…”

We used the Agriculture and Land Use National Greenhouse Gas Inventory Software to estimate the total greenhouse gas (GHG) emissions from the Nigerian agriculture sector in 2010. We went ahead to project future GHG emissions up to 2050. Two alternative GHG mitigation scenarios such as moderate (MS) and aggressive (AS) scenarios were developed and examined. Our results showed that total GHG emissions from Nigerian agriculture in 2010 were around 34.9 million tonnes of carbon dioxide equivalent. GHG emissions from livestock accounted for about 69.2 % of the total emissions, making it the largest source of GHG emissions in the sector. Nigeria's agriculture GHG emissions are expected to increase by 94 % in 2050 relative to 2010 levels. Mitigation strategies in the Nigerian agriculture sector that do not compromise food security are limited. However, with the implementation of different GHG mitigation strategies in the alternative scenarios, emissions are expected to fall by around 13.2 % and 26.7 % by 2050 in the MS and AS, respectively, compared to the baseline scenario. While the mitigation potentials are significant, we argue that robust and dedicated policies are required to accelerate climate-smart agriculture in Nigeria.Keywords ALU software program • Enteric fermentation • Greenhouse gas • IPCC • Livestock • Nigeria 1 Information derived from World Economic Forum (WEF): https://www.weforum.org/agenda/2016/05/70-of-africans-makea-living-through-agriculture-and-technology-could-transform-theirworld/.

Agricultural waste management for horticulture revolution in sub-Saharan Africa

et al. 2020

Agricultural activities, which basically involve the production of raw produce and subsequent value addition normally, generate substantial waste, which could be in solid, liquid or gaseous forms. In sub-Saharan Africa (SSA), the disposal of these wastes, which come from a myriad of sources or agricultural activities, constitutes a huge challenge. Even though these wastes are economically viable when properly managed by conversion to organic fertilizer and eventual use in crop production, they often exert hazardous effect on the environment due to improper disposal or management. Properly managed wastes deployed in conservation agriculture could enhance ecological balance and ensure sustainable crop production system intensification leading to elevated levels and quality of yield. Positive utilization of these wastes holds great prospects for SSA, which is characterized by accelerated population growth that puts undue pressure on available land, declining soil fertility and crop yield as well as high rate of youth unemployment. Horticulture essentially involves intensive cultivation of specialty crop (fruits, vegetables, ornamentals, seedlings) and, thus, often pays special attention to soil fertility management. The crops are largely grown under protected environments (modified or controlled environments), consequently, requiring among other variables high soil/ substrates fertility. Organic manure generated from agricultural wastes is a putative source of good-quality and cheap nutrients for optimum crop performance. Converting large volume of available agricultural wastes in SSA to organic manure for horticultural field production and/or to organic substrates for protected crop production and commercial nursery will revolutionize horticultural industry in the subregion. This review explores the various types of agricultural wastes generated in SSA, their possible or potential utility in the horticulture industry and advocates their proper management and utilization in horticulture to enhance environmental quality, increase crop yield and quality and improve economies and livelihoods across SSA.
