• Most of the NbS of Tropical drylands of India are not follow the IUCN standard criteria. • The Identified NbS are baised towards environmental services than addressing social needs of the people. • Improved NbS interventions requires intensive enagement of stakeholders for addressing social causes. Nature-based Solutions (NbS) is a flexible, adaptable, and multi-functional strategies employed to address climate change. However, all the claimed NbS are actually do not adhere the criteria of being NbS. Therefore, present study analysed 87 articles to appraise adherence of potential NbS as per the IUCN Global Standard, along with evaluation of flow of associated ecosystem services (ES). The review identified 39 interventions, out of which only twelve interventions adhered the criteria of NbS. Among the classified NbS, two interventions, namely, sustainable forest management (SFM) (80.83%) and haveli rejuvenation (75.61%) strongly adhered to the IUCN Standard. Lack of adherence in the non-classified NbS interventions was mainly attributed to absence of information on inclusive governance, monitoring and associated trade-offs. The identified 39 interventions were also observed to be enhancing a total of 37 ES, evaluated through 37 distinct indicators i.e. different and enhanced flow of ES were observed by the different NbS. However, the majority of classified NbS were biased towards flow of environmental services than social services. Present study results that all claimed NbS cannot fulfilled the intended objectives of NbS and thus cannot be classified under the NbS as per global standard. Moreover, assessing the flow of associated ES may be an additional support to broaden the scope of NbS implementation. Therefore, present study also highlights to integrate the flow of ES along with the adherence criteria of NbS. Moreover, the review also facilitate to understand constraints associated with the implementation of potential NbS interventions and thus, suggests considering wider aspects in the future researches for assessing the implementation of NbS.

Even though oil, gas, and coal resources might be unavailable after 2040, 2042, and 2112, respectively; 81.7% of the energy is produced from fossil fuels. Experts have established that this level of non-renewable resource use is unsustainable, ecologically unsafe, and critically changing climate patterns. Whereas climate change and biodiversity loss have subjected mankind to significant systemic risks, policymakers have recommended a switch from fossil fuel-based to a biobased economy and reconnecting humans with the biosphere as a way to mitigate these risks. A circular bioeconomy has been suggested as an efficient approach to utilize environmentally safe ecosystem services for socio-ecological development and transformation towards sustainability. The circular bioeconomy provides significant opportunities to achieve 17 SDGs and 134 targets of the Sustainable Development Agenda 2030, and address numerous national and international challenges caused by climate action. In this review, we have highlighted links between circular bioeconomy and internationally agreed SDG targets [particularly SDG 13 (climate action)]; and assessed ecosystem services in a circular biobased economy. A critical synthesis vis-à-vis climate action through circular bioeconomy to assure the sustainability of bioeconomy programmes is herein presented. [Display omitted] • Switching to a biobased circular economy is a perfect strategy for climate action. • Ecosystem services are valuable for the execution of circular bioeconomy policies. • Circular bioeconomy framework involves living feedstock conversion into useful products. • Linking bioeconomy programmes to SDGs assure their sustainability.
