“…In July 2023, extraordinarily heavy rains in Beijing caused severe damage in Mentougou and other districts. The same problem occurred in megacities such as Mexico City, London, Paris, and Atlanta [31][32][33], all of which are at risk from climate change. These risks require responses to improve the resilience of cities.…”

Climate change and biodiversity loss are two major threats to the world. Ecosystem conservation is an important issue for humanity, and international intergovernmental science-policy platforms highlight the mutually beneficial relationships among biodiversity conservation, ecosystem services and measures to mitigate climate change. Rapid urbanization has brought various deeply interconnected ecological problems to large cities. Therefore, key areas for conservation must be identified in an integrative manner to maximize conservation effectiveness and meet both ecological and human social needs. Spatial conservation prioritization provides a way to consider different functional needs as a whole in light of certain objectives while highlighting their contradictions and overlaps in spatial utilization. The megacity of Beijing continues to experience frequent extreme weather events despite the implementation of a series of ecological restoration measures. We integrated the potential distributions of 64 critically endangered native species to represent biodiversity and used five main ecosystem services required for climate governance to represent ecosystem services in the city. Using the spatial prioritization software Zonation 5, we assessed the spatial distribution of conservation priorities at the municipal scale and changes in conservation effectiveness in four protection scenarios. The results showed that the existing PAs in Beijing could protect 24.99% of the current distribution of biodiversity and ecosystem services. The conservation effectiveness can reach 78.75% when the PAs are increased to 30%. This efficiency rate is 4.46% lower than that of the optimal scenario, which does not consider the existing PAs. An emphasis on urban rewilding spaces may be the key to overcoming conservation bottlenecks to further enhance the efficiency of ecological conservation. To achieve future conservation targets, policy development may start with urban built-up areas.

“…The studies we consulted reported 64 aquatic species that could somehow be contemplated in that location. Riparian zones and mangroves along the water bodies present are highly depauperated, and could play an important role to improve connectivity in the urban landscape (Ribeiro et al, 2022). Along the Jacaraípe river, a few small patches of mangrove remain.…”

Urbanization is recognized as an important cause of biodiversity loss. Urban areas present reduced number of bird species if compared to non-urban more pristine areas nearby. The goal of this research is to help improving the diversity of birds in urban areas by investigating why an urban area in the coast of Brazil sustains a small fraction of the species that could occur in the region. We conducted observations during two years in Serra, Brazil, resulting in the identification of 27 bird species visiting a residential garden. Studies in the region have reported 275 species. We used GIS maps and aerial photos to analyse the landscape, then discussed that numeric discrepancy and the possible reasons for the reduced diversity, contrasting it to the resources available in that landscape. Recent urbanization is likely to be a major cause of the low diversity, but the study area has been subject of change from the original ombrophilous dense forest to agriculture and pasture before the consolidation of the current urban land uses. Albeit the landscape is highly fragmented, diverse landcover types have recovered in recent decades, creating a mosaic of small isolated patches of forest, mangrove and restinga, the three major ecosystems in the region. We expect that our findings create a foundation for further exploration of measures and policies for implementing greenspace within cities that help reverting the current status and improving the diversity of birds in tropical cities.

“…The loss and gain of forested areas have an impact on biodiversity. The loss of habitat for species, many of which are endemic, in areas such as the Amazon region, causes imbalances in these natural environments, which could take years or may not be able to recover depending on the size of the impact [13,74,75].…”

“…Thus, understanding the recent and anticipated structure and dynamics of land use becomes essential for landscape management and aids in the implementation of public policies and environmental prevention aimed at preserving and conserving the Amazon biome. In this context, geotechnologies serve as fundamental tools for this study [4,[12][13][14]. The combined use of remote sensing techniques, geographic information systems (GIS), and terrestrial environment modeling allows for the analysis of changes in behavior as well as the simulation of future scenarios.…”

The objectives were to analyze the dynamics of land use and land cover of the Amazon biome over time through spatial modeling, and project its future scenario with the Land Change Modeler (LCM) module. This analysis was based on 1985, 2014 and 2017 land cover data from the MapBiomas project, which was associated with socioeconomic explanatory variables based on the Cramer-V test. Results showed that the Forest Formation class occupied 3,844,800.75 km2 (91.20%) in 1985, and in 2014, there was a reduction to 3,452,129.25 km2 (81.89%). The pasture class had an initial area of 71,046.50 km2 (1.69%), and in 2014, there was an expressive increase to 437,670.00 km2 (10.38%). The analysis made it possible to verify that Forest Formation and Pastures were the classes that suffered the most changes, followed by the Annual and Perennial Culture and Mosaic of Agriculture and Pasture. The projected land use and coverage for 2044 suggests that there will be a reduction in Forest Formation due to a significant increase in the Pasture class. The simulations foreseen in this work are an important tool that can provide subsidies for supporting territorial planning in the region, public policies, and encouragement of best practices with a reduced impact in pasture areas.
