Harvest Cool

农业在尼日利亚经济中发挥着重要作用，占国内生产总值的22.35%（2021年），并在生计水平上雇用了70%以上的人口（1）。洋葱是一种利润丰厚的旱季灌溉作物，主要在尼日利亚北方生产，年产量约为2 Mt。洋葱种植者的机会并没有完全实现，因为农艺措施的投资低，收获后损失（高达50%）。传统的洋葱干燥可以被一个从田间到市场的冷却供应链所取代，然而，冷却能源的获取阻碍了这一倡议。Harvest Cool项目代表了来自农业企业、农业服务和技术提供商的利益相关者，他们将提供一个综合能源系统，为尼日利亚种植的洋葱开发一个低碳冷藏系统。该伙伴关系包括PyroGenesys（生物质热解技术）、Lavender Fields（农产品聚合商和销售商）、尼日利亚农业综合企业集团和Agrolog（农业推广服务，尼日利亚）以及伦敦大学学院（生命周期评估投入）。该项目建立在Lavender Fields开展的可行性研究的基础上，确定了向尼日利亚卡诺的一个主要洋葱市场（Karfi）销售的农业社区，这些社区显然需要为易腐作物开发冷藏供应链。该项目创新地汇集了独特的工程设计，解决了从田间运输到中央储存点的冷藏问题。该项目在商业模式的概念上也具有创新性，考虑到能源供应;减少食物浪费的好处;为低收入农业社区增加价值;以及一个有潜力改善农业条件和土壤固碳的循环碳农业系统。该项目将通过全球变暖潜能值的生命周期评估进行定量评估通过社区互动计划，展示项目对解决可持续发展目标7可负担的清洁能源和可持续发展目标13气候变化的贡献。参考资料（1）https://www.fao.org/nigeria/fao-in-nigeria/nigeria-at-a-glance/en/

Agriculture plays a significant role in the Nigerian economy, contributing 22.35% GDP (2021) and employing \>70% of its population at subsistence level(1). Onions are a lucrative, dry season irrigated crop and ~2 Mt/annum are produced, largely in Northern Nigeria. Opportunities for onion farmers are not fully realised, due to low investment in agronomic practices, and post-harvest losses (up to 50%). Traditional drying of onions could be replaced by a cool supply chain from field to market, however, access to energy for chilling hampers this initiative.The Harvest Cool project represents stakeholders from farming business, agricultural services, and technology providers who will deliver an integrated energy system to develop a low carbon cold storage system for onions grown in Nigeria. The partnership comprises PyroGenesys (biomass pyrolysis technology); Lavender Fields (agricultural produce aggregator and marketer); the Nigeria Agribusiness Group and Agrolog (agricultural extension services, Nigeria) and University College London (Life Cycle Assessment input). The project builds on a feasibility study carried out by Lavender Fields, identifying farming communities which sell to a major onion market (Karfi) in Kano, Nigeria, with a demonstrable need to develop cool supply chains for perishable crops.The project is innovative in bringing together unique engineering designs which address cold storage for transport from the field to a central storage point. The project is also innovative in the conception of a business model which considers energy provision; the benefits of food waste reduction; adding value to low income farming communities; and a circular carbon farming system with potential to improve agronomic conditions and carbon sequestration in soils.The project will be assessed quantitatively through Life Cycle Assessment of global warming potential (GWP) of the overall system and qualitatively through a programme of community interactions, demonstrating the project's contribution to addressing SDG7 Affordable and Clean Energy and SDG13 Climate Change.REFERENCES(1) https://www.fao.org/nigeria/fao-in-nigeria/nigeria-at-a-glance/en/
