The intention of this review is to place crop albedo biogeoengineering in the wider picture of climate manipulation. Crop biogeoengineering is considered within the context of the long-term modification of the land surface for agriculture over several thousand years. Biogeoengineering is also critiqued in relation to other geoengineering schemes in terms of mitigation power and adherence to social principles for geoengineering. Although its impact is small and regional, crop biogeoengineering could be a useful and inexpensive component of an ensemble of geoengineering schemes to provide temperature mitigation. The method should not detrimentally affect food security and there may even be positive impacts on crop productivity, although more laboratory and field research is required in this area to understand the underlying mechanisms.
本综述的目的是将作物反照率生物地理工程置于更广泛的气候操纵图景中。作物生物地理工程是在几千年的农业土地表面长期改造的背景下进行考虑的。生物地理工程也从减缓能力和遵循社会工程原则的角度与其他地球工程方案进行了批判。尽管其影响较小且具有区域性，但作物反照率生物地理工程可能是一组地球工程方案的有用且廉价的组成部分，可用于提供温度缓解。该方法不应对粮食安全产生不利影响，甚至可能对作物生产力产生积极影响，但在这方面需要更多的实验室和现场研究，以了解潜在机制。
