Abstract Nature-based solutions have gained popularity as an approach to reduce the impacts of climate and environmental change, providing multi-fold multi-sectoral benefits especially in cities. Yet there has been growing concern about their utility for cities Global South, a fuelled by paucity studies, including scientific peer reviewed gray literature. In this paper, we contribute knowledge gap, based on analysis 120 case studies NBS South cities, documented two databases (Urban Natural Atlas Oppla). These cases fall largely under categories blue green infrastructure, with few also focusing grey infrastructure (in buildings or campuses). While most are Asia, several Africa Central/South America. Two-third aligned towards either national, lower-level (regional local) policies indicating importance policy mechanisms driving implementation. Institutional arrangements usually non-government, government collaborative arrangements, goal resilience, biodiversity support ecosystem restoration—along social goals creating public spaces. However, when private players take mandate NBS, they focus primarily campuses), meant employee benefits, not public. where engagement is stated priority, find tokenistic approaches deployed, seeking through information dissemination consultation predominate. Despite participation engagement, only focused empowerment co-creation local communities. We suggest that greater need documentation regarding modes roles levels actors involved, enrich our understanding impact values justice equity global South.

Resilience is a widely debated concept that encompasses various interpretations. Recently, in science and policy circles, there has been growing interest the of Social-Ecological-Technological Systems (SETS) resilience which offers new interpretation. While this now used frequently, it not properly understood still lack clarity on what means its underpinning principles. This understanding may confuse even disorient researchers makers. To address issue, we review literature published context urban systems. The reviewed mainly focused nature-based solutions, indicating more contributions from ecological field. Also, flooding, extreme heat, drought are major stressors discussed literature. We elaborate definition SETS discuss dominant principles adaptability, transformability, flexibility, redundancy, equity, diversity, foresight capacity, connectivity, robustness, multi-functionality, learning, non-linearity. also expound upon key components SETS, how they intertwined, potential trade-offs emerge between them. Our study demonstrates implementation approach leads to numerous ancillary benefits. If multi-level polycentric governance strategies adopted, can help avoid social, ecological, technological dimensions. conclude by emphasizing dominated epistemological approaches empirical research needed understand better complex dynamics resilience.

Abstract The Tibetan grassland ecosystems possess significant carbon sink potential and have room for improved sequestration processes. There is a need to uncover more ambitious coherent solutions (e.g., Nature-based Solutions) increase sequestration. Here, we investigated the rationale urgency behind implementation of Solutions on sequestering using literature review meta-analysis. We also project changes in terrestrial Plateau model simulations with different future emissions scenario. results show that Solution projects are expected by 15 21 tetragrams 2060. defined conceptual framework integrates initiatives restoration degraded grasslands Our consists four stages: theory, identification, practice, goal.

Abstract A growing number of Nature-based Solutions (NbS) has been advocated for urban flood risk management (FRM). However, whether NbS FRM (NbS-FRM) achieves both social and ecological co-benefits remains largely unknown. We here propose use a conceptual framework with coupled social-ecological perspective to explore identify such “win-win” potential in NbS-FRM. Through scoping-review we find that measures are unevenly distributed around the world, those solely targeting mitigation may have unintended negative consequences society ecosystems. In elaborating this evidence from reviewed studies, NbS-FRM provide co-benefits, remaining gaps including lack resilience thinking, inadequate consideration environmental changes, limited collaborative efforts manage trade-offs. The proposed shows how move forward leverage equitable sustainable improved human well-being ecosystem health.

Nature-based solutions (NbS) are increasingly recognised for their potential to address both the climate and biodiversity crises. Both these outcomes rely on capacity of NbS support enhance health an ecosystem: its biodiversity, condition abiotic biotic elements, continue function despite environmental change. However, while understanding ecosystem change mitigation has developed in recent years, those implemented adaptation remain poorly understood. To this, we systematically reviewed 109 nature-based interventions using 33 indicators across eight broad categories (e.g., diversity, biomass, composition). We showed that 88% with reported positive also benefits health. were associated a 67% average increase species richness. All studies supported health, leading “triple win.” there trade-offs, mainly forest management creation novel ecosystems such as monoculture plantations non-native species.

The concept of nature-based solutions (NbS) has been endorsed by multiple international organizations as one the priority approaches to address climate-related challenges. These are versatile, and can simultaneously challenges such climate impacts, public health, inequality, biodiversity crisis, being uniquely suited for urban adaptation.
