“…Both indices reflect the flow of ecosystem services in the landscape, given their sensitivity to fluctuations in energy, water, CO 2 , nutrients and biomass. All these are essential factors for the presence of ecological support processes in the landscape (Bonam, 2008;Costanza et al, 2017) features that contribute to resilience and ecological integrity: significant presence of moisture and organic matter in the soil, permeability, photosynthetic efficiency, evapotranspiration and resistance of vegetation to droughts (Bonam, 2008;Xu et al, 2008;Silva and Baptista, 2015;He et al, 2016;Radula et al, 2018;Amaral et al, 2020).…”

“…Although studies on the operationalization of ecosystem services are incipient (La Notte et al, 2017;Potschin and Haines-young, 2017;Amaral et al, 2020), it is known that primary production, nutrient cycle and soil formation are intertwined with the presence of vegetation in the territory, with an emphasis on the arboreal type and its performance in carbon sequestration, which, when effective, can be considered carbon sinks. Thus, there will be areas in the territory that perform the role of carbon sequestration in the landscape, through the integrity of their supporting ecological processes.…”

“…In this way, the quantification and qualification of carbon becomes relevant so that future intervention decisions can be supported with occupations that allow for such functions, providing a territorial planning decision-making integrated with nature. These relationships are subject to several explorations through remote sensing, whose spatial and temporal analysis can simplify and improve merely quantitative assessments (Amaral et al, 2020;Li et al, 2020;Correia Filho et al, 2021;Kopecky et al, 2021).…”

“…biodiversity, vegetation evapotranspiration, formation of macropores and micropores in the soil. When such functions, alone or combined, are perceived as benefits to human well-being, they become ecosystem servicesreduction of heat islands, availability of fresh water, drought resistance and natural soil drainage (Hallet et al, 2013;Costanza et al, 2017;Amaral et al, 2020). In short, the provision of ecosystem services varies according to the functional integrity of ecosystems and is related to a constant base of supporting ecological processes.…”

“…This gap is highlighted in recent studies (B elanger, 2017;Costanza et al, 2017;Potschin and Haines-young, 2017) that point to the demand for the elucidation of characteristics and classifications that lead to the understanding and instrumentalization of the biophysical bases that support the ecosystem services as essential in structuring the landscape. Along these lines, a solution to this gap lies in understanding the link between primary production, the nutrient cycle and soil formation and ecological processes intertwined with the flow of carbon in the landscape with reflections on ecological integrity, biodiversity and the resilience of ecosystems (Amaral et al, 2017;Amaral et al, 2020).…”

PurposeHuman actions on natural ecosystems have not only jeopardized human well-being but also threatened the existence of other species. On the other hand, the benefits resulting from a greater integration between the logic of nature and human occupations have been seen as motivating factors for the prevention and mitigation of environmental impacts in landscape planning, since it provides human well-being through the grant of resources, regulation of the environment and socio-cultural services called ecosystem services. This article highlights the relevance of using ecosystem integrity indicators related to the functioning of ecological support processes for landscape planning.Design/methodology/approachThe research used the photosynthetic performance of vegetation through carbon fluxes in the landscape, defining areas where different approaches to green infrastructure can be applied, gaining over the majority of work in this area, in which low degrees of objectivity on measurement and consequent ecological recovery still prevail. Thus, using the conceptual support of restoration ecology and remote sensing, the work identified different vegetation performances in relation to the supporting ecological processes using the multispectral CO2flux index, linked to the carbon flux to identify the photosynthetic effectiveness of the vegetation and the Topographic Wetness Index (TWI).FindingsWith a study in the Distrito Federal (DF), the results of the different performances of vegetation for ecological support, through electromagnetic signatures and associated vegetation formations, allowed for the identification of hotspots of greater integrity that indicate multifunctional areas to be preserved and critical areas that deserve planning actions using green infrastructure techniques for their restoration and integration into the landscape.Originality/valueThis approach could be the initial step towards establishing clear and assertive criteria for selecting areas with greater potential for the development of supporting ecological processes in the territorial mosaic.

Aim: The aim of this study is to investigate the measurement of landscape integrity based on ecological support processes in the Federal District, with the aim of defining a multi-scalar and multi-functional Regional Green Infrastructure Network (IVR) based on Nature-Based Solutions (NBS). Theoretical Framework: This topic presents the main concepts and theories that underpin the research. Landscape Ecology, Restoration Ecology, Green Infrastructure and Geodesign stand out, providing a solid basis for understanding the research context. Method: The methodology adopted for this research comprises the analysis of ecological support processes in the landscape, using the multispectral “CO2flux” index, related to the photosynthetic efficiency of vegetation and a proxy for energy, carbon and biomass inputs, which, together with the “Topographic Wetness Index”, related to the flow and accumulation of water and sediment in the landscape, provided the basis for the elaboration of a Geodesign process. Data was collected using multispectral satellite scenes - “Landsat 8”, collected during the dry season. Results and Discussion: The results obtained revealed the design of a mosaic of “hotspots”, corridors and patches that consolidates and intensifies carbon flows in the Federal District's landscape, with positive impacts on territorial resilience. In the discussion section, these results are contextualized in the light of the theoretical framework, highlighting the implications and relationships identified. Possible discrepancies and limitations of the study are also considered in this section. Research Implications: The practical and theoretical implications of this research are discussed, providing “insights” into how the results can be applied, or how to influence practices in the field of landscape planning. These implications can cover the design of Nature-Based Solutions at a regional scale, climate mitigation and adaptation actions for territories, and people's access to ecosystem services. Originality/Value: This study contributes to the literature by proposing the design of a regional network of green infrastructures based on the analysis of the flow of ecological support processes in the landscape, considering different demands and goals for environmental recovery. The relevance and value of this research is evidenced by the possibility of planning and designing mosaics in the landscape based on the identification of networks with greater potential for the provision of ecosystem services and, consequently, for the adaptation and mitigation of territories to climate impacts and those resulting from human occupation.
