Abiotic stress maps for rice (STRASA): Maps (tiff) for Africa with probability of presence of a soil with high iron content overlaid with crop maps to identify areas with lots of iron AND lots of rainfed lowland rice

This dataset is produced for the STRASA project in which breeders are developing varieties tolerant to iron toxicity. The intended use is that tolerant varieties can be sent to places with high risk of iron toxicity. This \"iron soils\" map was combined with three crop maps (GAEZv3, MIRCA2000,SPAM2005) and multiplied with country specific fractions rainfed lowland rice from Diagne et al. (2013) because iron toxicity occurs predominantly in poorly drained rainfed lowland rice soils and rarely in upland or irrigated rice.

本数据集为STRASA项目的研发成果，该项目中育种学家正培育耐铁毒性的水稻品种。其预设用途为将耐铁毒性品种推广至铁毒性高风险区域。本数据集将"铁毒性土壤"分布图与GAEZv3、MIRCA2000、SPAM2005三款作物分布图进行融合，并与Diagne等人（2013）提出的各国雨育低地水稻占比系数相乘。这是因为铁毒性主要发生在排水不良的雨育低地稻田土壤中，极少出现在旱地或灌溉稻田的土壤环境内。
