Abstract

An increasing world population is projected to increase water, energy and food requirements, three vital resources for humankind. Projected climate change impacts will aggravate water availability, as well as flood risks, especially in urban areas. Nature-based solutions (NBS) have been identified as key concepts to defuse the expected tensions within the Water-Energy-Food (W-E-F) nexus due to their multiple benefits. In this paper, the authors outlined the theories and concepts, analyzed real-life case studies, and discussed the potential of NBS to address the future W-E-F nexus. For this purpose, we performed a systematic literature review on the theories of NBS that address the W-E-F nexus, and we summarized 19 representative real-life case studies to identify the current knowledge gaps and challenges. The quantitative and qualitative data was used to differentiate and discuss the direct and indirect potential benefits of NBS to the W-E-F nexus. The study further expanded on the challenges for the implementation of NBS and highlighted the growing possibilities in the context of circularity and the implementation of NBS in urban planning. It was concluded that the potential impacts of NBS on the W-E-F nexus have been identified, but the quantitative effects have not been analyzed in-depth. Moreover, indicators are mostly single-purpose and not multipurpose, as required to fully characterize the W-E-F nexus and circularity holistically. Overall, there is a need to adopt systemic thinking and promote the multipurpose design of NBS.

  • Cross-scale and cross-sector urban planning, such as blue-green infrastructure and food-water-energy nexus planning, is often nonexistent or lacking integration.

    “Further, cross-scale and cross-sector urban planning, such as in the case of blue-green infrastructure and food–water–energy nexus planning, is often nonexistent or lacking integration (38, 71).”

    From Global synthesis and regional insights for mainstreaming urban nature-based solutions (2025) · cites this paper as [38]

    Section 4.2 identifies difficulty scaling local nature-based solutions and integrating site-specific solutions into an interlinked green-infrastructure framework. Section 4.2.2 says these solutions are frequently treated as monofunctional. These passages support a lack of integration in this area, but do not establish that cross-scale and cross-sector urban planning is often nonexistent more generally. (LLM, conf=0.83)

  • Lack of systematic monitoring and evaluation schemes blocks information flows and evidence for making a business case for NbS critical for scaling up implementation.

    “This in turn blocks information flows and evidence for making a business case for NbS critical for scaling up implementation (38).”

    From Global synthesis and regional insights for mainstreaming urban nature-based solutions (2025) · cites this paper as [38]

    Section 4.1 says a lack of information makes NbS benefits difficult to quantify and notes that some implementers do not monitor or assess results. Section 4.2.2 says better economic assessment methods would facilitate upscaling. The paper does not explicitly say that absent monitoring blocks information flows or prevents a business case; that causal formulation is stronger than its account. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Gaps in empirical evidence, data, and indicators of NbS functioning prevent accurate parameterization and validation of models and development of future scenarios.

    “Further, gaps in empirical evidence, data, and indicators of NbS functioning prevent accurate parameterization and validation of models and development of future scenarios (38, 91).”

    From Global synthesis and regional insights for mainstreaming urban nature-based solutions (2025) · cites this paper as [38]

    Section 4.1 reports scarce case-study data, limited quantification of NbS benefits, and a lack of standardized indicators. Section 4.2.2 says holistic models are not readily available and discusses assessing different scenarios. Neither section says that these gaps prevent accurate model parameterization or validation, or the development of future scenarios. Page numbers are unavailable in our copy. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Global South cities were often noted as locations of knowledge gaps, with regionally appropriate knowledge generally scant on how to adapt local NbS to larger scales.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
