Conventional physico-chemical remediation is typically unaffordable in these settings and poorly suited to the diffuse, multi-metal contamination characteristic of SSA mining landscapes. This PRISMA-2020-aligned systematic review synthesises the evidence base for bioremediation of mining-derived waste in SSA, identifying the biophysical, operational, and socio-economic conditions under which laboratory innovation translates to field-realistic application. Following PRISMA 2020, we synthesised 75 sources (69 articles, 6 grey-literature reports; January 2020 to mid-2026) drawn from six databases plus targeted grey-literature channels. Two reviewers screened, extracted, and appraised each source, with third-reviewer adjudication. Risk of bias was assessed using an adapted CASP checklist. Four findings emerged; First, SSA harbours distinctive autochthonous resources: Cu\u002FCo-tolerant mycobiota dominated by Basidiomycota (64.6%) and Ascomycota (21.3%), native hyperaccumulator flora (shoot Cu up to ~13,700 mg kg –1 in Aeollanthus subacaulis var. linearis ), and arbuscular mycorrhizal consortia. Second, laboratory efficacy is high: bioleaching achieves 65–88% Cu recovery; sulfate-reducing bacteria remove 70–95% of dissolved metals; biosorption with fungal\u002Fagricultural-waste biomass removes 60–90% of Cu, Pb, and Cd. Third, field efficacy is consistently attenuated (factors ≈0.20–0.55), driven by ASM governance fragmentation, francophone\u002Flusophone indexing deficits, land-tenure insecurity, weak regulatory enforcement, and subsistence-economy coupling. Fourth, mineral-recovery economics can partly underwrite remediation, but no techno-economic case alone closes the lab-to-field gap. Operationalising SSA’s biological capital requires tiered lab-to-pilot-to-field pipelines with mandatory geochemical baselines, ASM formalisation backed by enforceable closure bonds, and active investment in francophone\u002Flusophone bibliographic coverage. Research priorities are SSA-specific reporting protocols, longitudinal climate-resilient field monitoring, life-cycle–techno-economic integration, vulnerability-differentiated impact assessment, and integration of remote sensing (Sentinel-2, hyperspectral, Landsat\u002FMODIS archives) with biological endpoints.","撒哈拉以南非洲是全球铜、钴、金和锡的生产中心，采矿活动——尤其是手工和小规模采矿——已使土壤、沉积物、水体和粮食作物受到砷、铅、汞、铜和钴的污染，且往往超过世界卫生组织（WHO）的阈值。传统的物理化学修复方法在这些地区通常难以负担，且不适合撒哈拉以南非洲采矿景观所特有的弥散性多金属污染。本系统综述遵循PRISMA-2020指南，综合了撒哈拉以南非洲采矿废弃物生物修复的证据基础，识别了实验室创新转化为实地应用所需的生物物理、操作和社会经济条件。按照PRISMA 2020框架，我们综合了75篇文献（69篇期刊论文、6篇灰色文献报告；2020年1月至2026年中），来源于六个数据库及定向灰色文献渠道。两名评审员对每篇文献进行筛选、数据提取和质量评价，并由第三名评审员裁定分歧。偏倚风险采用改编的CASP清单进行评估。研究得出四项发现：第一，撒哈拉以南非洲拥有独特的本土资源：以担子菌门（Basidiomycota，64.6%）和子囊菌门（Ascomycota，21.3%）为主的耐铜\u002F钴真菌群落、本土超富集植物区系（Aeollanthus subacaulis var. linearis地上部铜含量高达约13,700 mg kg⁻¹），以及丛枝菌根共生体。第二，实验室效能较高：生物浸出可实现65–88%的铜回收率；硫酸盐还原菌可去除70–95%的溶解态金属；利用真菌\u002F农业废弃物生物质的生物吸附可去除60–90%的铜、铅和镉。第三，实地效能持续衰减（衰减因子约为0.20–0.55），驱动因素包括手工和小规模采矿治理碎片化、法语\u002F葡语文献索引不足、土地权属不安全、监管执法薄弱以及生计经济耦合。第四，矿物回收经济收益可部分支撑修复成本，但仅靠技术经济论证无法弥合实验室到实地的差距。要将撒哈拉以南非洲的生物资本投入实际应用，需要建立实验室—中试—实地的分级管道，强制实施地球化学基线监测，在可执行的闭矿保证金支持下推进手工和小规模采矿正规化，并积极投资于法语\u002F葡语文献覆盖。研究优先方向包括：撒哈拉以南非洲专属报告规范、纵向气候韧性实地监测、生命周期—技术经济整合、脆弱性差异化影响评估，以及遥感（Sentinel-2、高光谱）技术的整合。",null,"Frontiers in Agronomy","2026-09-17T00:00:00Z","论文",10,false,84,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":13,"relevant":21,"comment":22},18,23,19,14,1,"PRISMA-2020系统综述揭示撒哈拉以南非洲矿区生物修复从实验室到田间的衰减规律，方法严谨、数据翔实，对农业环境治理与污染耕地修复有参考价值。",[24],{"name":10,"url":6},[26,27,28,29,30],"土壤修复","农业环境","矿山治理","重金属污染","生物修复",0,"10.3389\u002Ffagro.2026.1939826",{"doi":32,"openalex_id":34,"authors":35,"venue":10,"cited_by_count":31,"oa_url":6,"card":47,"direction":53,"ingested_from":54},"W7213466518",[36,38,40,43,45],{"name":37,"orcid":9},"Daniel Masumbuko Nhunda",{"name":39,"orcid":9},"Mohanadoss Ponraj",{"name":41,"orcid":42},"Charles Bwalya Chisanga","https:\u002F\u002Forcid.org\u002F0000-0002-7388-5415",{"name":44,"orcid":9},"Subbaiya Ramasamy",{"name":46,"orcid":9},"Stephen Syampungani",{"tldr":48,"method":49,"finding":50,"direction":51,"opportunity":52},"系统综述撒哈拉以南非洲采矿废弃物生物修复证据，揭示实验室高效但田间效果衰减的鸿沟。","PRISMA-2020系统综述，75篇文献，CASP偏倚评估，涵盖生物浸出、SR","实验室金属去除率60-95%，但田间效率衰减至0.20-0.55，受治理与土地权属制约。","农业绿色发展与碳","可探索遥感与生物修复耦合的田间监测，以及法语\u002F葡语区数据缺口与全生命周期经济评估。","农业遥感与作物表型","openalex","2026-09-17T23:30:34.520300Z"]
