土壤是地球上重要的生命维持系统。然而，据估计，全球约25%的土壤高度退化，44%的土壤中度退化，主要原因是金属和类金属、持久性有机污染物、农药、放射性核素等污染。此外，抗生素、消毒剂、阻燃剂、纳米颗粒等新兴污染物的污染对土壤系统的动态平衡构成了额外的威胁。因此，污染土壤的可持续管理对于维持生态系统服务至关重要。虽然化学和物理方法被广泛用于污染土壤的修复，但植物技术（基于植物的清理技术）作为一种清洁和碳中性的解决方案，在修复和可持续管理污染土壤方面，其重要性大于植物技术，而且往往更受青睐。除此之外，植物清理还为修复期间的生物企业活动提供植物产品，如生物质、生物燃料和其他工业上重要的化学品。然而，植物修复在被混合/多重污染物污染的土壤中不能得到理想的结果。此外，气候变化如何影响土壤系统中植物与微生物的相互作用和污染物的行为尚不清楚。此外，关于气候变化下植物-微生物-污染物关系的信息有限。因此，目前的工作旨在(i)解决修复被多种污染物污染的土壤的困难；（ii）描述植物-微生物-污染物和气候关系；（iii）确定评估修复系统的关键可持续性指标。
Soil is a vital life supporting system of the Planet Earth. However, it has been estimated that around 25% the global soils are highly degraded and 44% are moderately degraded mainly due to the pollution of metals and metalloids, persistent organic pollutants, pesticides, radionuclides etc. Additionally, the pollution due to new and emerging pollutants such as antibiotics, disinfectants, flame retardants, nanoparticles etc pose an additional threat to the homeostasis of the soil system. Therefore, sustainable management of contaminated soils are essential for maintaining the ecosystem services. Though chemical and physical methods are widely pursued for the remediation of contaminated soils, phytotechnolgies (plant-based clean-up technologies) are outweighed and often preferred as a clean and carbon-neutral solution for the remediation and sustainable management of the contaminated soils. Apart from that, plant-based clean-up also provide phytoprodcuts such as biomass, biofuels and other industrially important chemicals for bio-based entrepreneurial activities during remediation. However, phytoremediation does not give desired results in soil contaminated with mixed/multiple pollutants. Furthermore, it is unclear that how changing climate will affect the plant-microbe interactions and pollutants behaviour in the soil system. Moreover, there is only limited information available on the plant-microbe-pollutants nexus under changing climate. Therefore, the present work is aimed to (i) address the difficulties in remediation of soils contaminated with multiple pollutants (ii) delineate the plant-microbe-pollutant and climate nexus and (iii) identify the key sustainability indicators for evaluating the remediated system.
