“…Em Belém, ilhas dos municípios de Belém e de Ananindeua e áreas protegidas ao sul da porção continental definem a cintura periférica externa, na medida em que a conurbação segue o eixo da rodovia. As cinturas periféricas internas estão desvanecendo, embora o corredor que corresponde ao trajeto do sauim de coleira 4 , tenha sido poupado por apelo dos ambientalistas, há expectativa de que toda a mata desapareça e que a Reserva Florestal Adolpho Ducke, área protegida retangular localizada ao norte da cidade, possa ser estudada como uma mancha fragmentada da floresta (Santos et al, 2022). Diante disso, vêse que mesmo os ambientalistas não conseguem vislumbrar uma solução que articule a geometria da ecologia da paisagem com a geometria do espaço construído.…”

O planeta está em uma emergência climática, e muito se fala sobre a prioridade de preservação de florestas, mas a conexão entre cidade e natureza ainda é pouco compreendida na floresta tropical brasileira. Na Amazônia, 80% da população vive em cidades, onde duas metrópoles – Belém e Manaus são referências para as cidades menores. Esta pesquisa identifica e espacializa as fases de formação de cinturas periférica para essas metrópoles, os processos socioeconômicos, usos e atores envolvidos na sua produção ou afetados por seu desaparecimento, sob a luz de uma socioecologia. As cinturas periféricas são marcadores de fases de expansão e estagnação nas duas cidades, onde as cinturas mais preservadas são aquelas destinadas a usos institucionais; porém, há rápido desaparecimento destes interstícios, seja por ocupação informal, seja por ação do setor imobiliário, face ao intenso fluxo migratório para as duas cidades. Conclui-se que a convergência entre aspectos ecológicos, de planejamento e morfologia urbanos é urgente porque tanto dentro quanto fora das cidades a floresta é meio de produção da população nativa e de prestação de serviços ecossistêmicos, e porque os circuitos curtos e fluxos de conexão entre cidade e floresta favorecem a vida tanto local quanto globalmente.

“…Brazil has a leading part in this problem as it has both the largest number of psittacine taxa and endangered species [9,10]. Since these birds are highly forest-dependent (70%) and the country still faces alarming rates of deforestation, parrots are likely to face even more severe declines shortly [9,11,12]. Despite this dire outlook, the group is highly represented in conservation actions that aim to reverse or compensate for the local extinctions that are already in progress [13].…”

The Golden Parakeet is an endemic Brazilian flagship species that has suffered from poaching and habitat loss, leading to local extinctions in the urbanized parts of the Amazon. We reintroduced six groups of mostly captive-bred parakeets in a protected area. The birds were acclimatized for at least five months at the release site, where they were trained to recognize native foods and develop foraging skills. Subsequently, we conducted a soft release, followed by daily supplementation and monitoring. For three years following the release we recorded their diet, feeding behavior, and how they adapted to wild foraging. The reintroduced birds fed on 23 plant species, with 13 not being previously listed in past studies. The three most consumed species corresponded to 77% of their feeding records. Parakeets spent more time feeding in altered landscapes and secondary vegetation than in the preserved forest. Most of the feeding happened during the rainy season when most of their favorite plants are fruiting. The parakeets’ incorporation of new species in their diet and their transition from supplemental to natural feeding happened gradually, as we did not reduce food offerings. Parakeets that showed site fidelity were able to find native food rapidly following release, but individuals that dispersed immediately had more difficulty finding food. This study showed that captive-bred Golden Parakeets can transition to a wild diet following a gradual reintroduction process.

“…With urbanization and industrialization, the demands of human activities on land resources are increasing, especially in developing metropolitan areas [44]. Although metropolitans have achieved remarkable progress in socioeconomic areas, unprecedented transformations in land use and cover have occurred and resulted in resources and environmental problems, such as declining air quality [45], extreme traffic by congestion [46], high potential in soil erosion risk [47], lowered water tables [48], urban waterlogging [49], deforestation [50], and occupied cropland [51]. At the same time, these consequences restricted the transition of socioeconomic areas and reduced the level of regional ecological security [52].…”

Scenario-based simulation in land use and cover change (LUCC) is a practical approach to maintaining ecological security. Many studies generally set constraints of LUCC utilizing ecological patches but without consideration of corridors connecting these patches. Here, we constructed a framework to balance urban growth and ecological security by integrating ecological security patterns (ESPs) into the PLUS model. This study selected Chang-Zhu-Tan Metropolitan Area (CZTMA) in central China as a typical case. Specifically, coupling quantitative demand with spatial constraints of multiple levels of ESPs, this study designed four scenarios, including historical tendency (HT), urban growth (UG), ecological conservation (EC), and coordinating city development and ecological protection (CCE). Then, the transformations and landscape patterns of LUCC were analyzed to evaluate the future land change from 2020 to 2050. The results show sixty-one key ecological sources in the CZTMA, mainly in higher-elevation forested areas. Forty-six ecological corridors were estimated using circuit theory. The building expansion was driven by accessibility to transportation and government locations and will contribute to the loss of forest and cropland in the future. The feature of different scenarios in alleviating the increasing fragmentation of patches and reducing the loss amount of ecological land showed EC > CCE > HT > UG. This study developed the ESP-PLUS framework and its modeling idea, which has the potential to be applied in other regions. This extension would assist decision-makers and urban planners in formulating sustainable land strategies that effectively reconcile eco-environmental conservation with robust economic growth, achieving a mutually beneficial outcome.
