“…The z value is the default parameter and is a normalized constant. The sensitivity of a habitat type to threats is based on the general principles of biodiversity conservation in landscape ecology [34][35][36]. The sensitivity of various land-use types to threats factors used in this study was listed in Table 4.…”

Dong Trieu district is a vital connection for territorial ecological security and human welfare between Hanoi (the capital of Vietnam) and Quang Ninh province. Therefore, habitat quality (HQ) is of extraordinary importance to the area’s sustainable development. The ArcGIS platform, Dyna-CLUE, and InVEST models were utilized in this study to assess the spatial and temporal transformations of land use and the changes of HQ in 2030 under various scenarios, with intentions to find strategies that may mitigate the HQ’s deteriorating trend in the district. Simulated results indicated that, assuming the development is maintained as usual, the average HQ of the District at 2030 could diminish by 0.044 from that of 2019 (a four-times decrease compared to the previous decade). Cases comprised of four basic scenarios, including development as usual, built-up expansion slowdown, forest protection emphasized, and agricultural land conversion, were used to identify potential strategies to mitigate the deteriorating trend. Simulated results revealed that keeping the built-up expansion rate lower than 100 ha y−1, the deforestation rate lower than 20 ha y−1, and preferring orchards over agricultural land conversion is required to limit the drop in HQ to within 0.01 in the next decade. Other than the existing population growth control policy, new guidelines such as (1) changing urban expansion type from outward to upward to control the built-up expansion rate, (2) substituting forest-harming industries to forest-preservation industries to reduce deforestation rate, (3) encouraging orchards preferred over agricultural land conversion to increase incomes while maintaining higher habitat quality, (4) practicing better farming technologies to improve crop production and to alleviate potential food security issues due to considerable reduction in cropland, and (5) promoting Green Infrastructure and the Belt and Road Initiative to increase urban green cover and raise residents’ income should be considered in designing the new mitigation strategies.

“…A Ecologia de Paisagem, com isso, envereda-se pelo entendimento quantitativo da estrutura paisagística, no intuito de compreender as interações entre os padrões da paisagem e processos ecológicos (TURNER, 1989). Três elementos são utilizados para a análise estrutural da paisagem, definidos em manchas (patches), corredores (corridors) e matriz (matrix) (Figura 1), pois possibilitam comparação e elaboração de princípios gerais sobre a paisagem (ABDALLA; CRUZ, 2015;CASIMIRO, 2009;FAHRIG, 2017;FORMAN, 1995;LANG;BLASCHKE, 2009;MCGARIGAL, 2015;MITCHELL et al, 2014;RESASCO et al, 2017;RUŽIČKA;MIŠOVIČOVÁ, 2009;SANTOS et al, 2017;SOUZA, 2014). Geralmente, esses elementos se distinguem em função do tamanho, números, formas e/ou gênese (RUŽIČKA; MIŠOVIČOVÁ, 2009).…”

No contexto geográfico, a Ecologia da Paisagem possibilita identificar fatores e implicações decorrentes da apropriação ambiental. As formas e os processos são mensurados através da descrição quantitativa e investigação sobre a estrutura da paisagem por uma variedade de índices. Por este estudo, objetivou-se analisar as métricas da paisagem para discutir sobre as alterações e impactos ambientais na estrutura da paisagem em uma escala temporal de cinco décadas, no intuito de acompanhar a evolução paisagística e discorrer sobre a deterioração ambiental no município de Canudos-BA. Esse localiza-se na Área Susceptível à Desertificação (ASD), no estado da Bahia, onde domina a aridez climática. A aplicação das métricas decorreu pela manipulação de cinco mapas de uso e cobertura da terra em ambiente de sistema de informação geográfica (SIG), a partir da definição de duas classes preponderantes, fragmento vegetal e polígono antrópico. Identificou-se a vegetação como a matriz da paisagem; no entanto, na depressão, onde o uso agropecuário é intenso, há um retalhamento vegetal e muitos fragmentos da caatinga arbórea e arbustiva diminuíram, desapareceram e encontraram-se mais espaçados entre os anos de 1977 e 2017. Em Canudos-BA, os polígonos antrópicos cresceram em uma média de 28,89% ao longo das décadas; em relação aos anos de 1977 e 2017, houve um aumento significativo de 503,82km2, equivalente a uma taxa de acréscimo de quase 100% da totalidade dos polígonos antrópicos. São áreas em que exigem práticas conservacionistas, para evitar a extinção das feições vegetais, exposição dos solos às intempéries e ampliação dos fatores de vulnerabilidade ambiental à desertificação.

“…Significant changes in creating urban greenery systems were affected by the concept of ecological patches and corridors by Forman and Gordon [9,10]. They assume a continuity of environmental linkages and their significance to environmental balance, biodiversity, and the self-renewal of ecosystems [11]. Green infrastructure is a contemporary concept that implies a strategically planned network of natural and semi-natural areas that perform social and economic function, but most importantly, they support biodiversity [12].…”

The article discusses the natural and historic heritage of medieval towns in the Opole Silesia region in the context of their ability to take advantage of their potential for sustainable development, especially in tourism. The chosen environmental, urban, architectural, and landscape factors were compared through this aspect and subjected to a multidimensional comparative analysis. The research studies applied mostly archival materials, contemporary topographic maps, statistical data, and both landscape as well as urban field studies. As a result, the studies indicated that the natural conditions of the locations, the preservation level of the urban system along with its development trends, and the areas of the old fortifications with their accompanying greenery constitute these towns’ very value and identity. As they combine elements of nature and culture, they may serve as the basis for development of tourism, which is likely to contribute to the social and economic revitalization of the region itself. What may play a major role in the quest for sustainable development are the urban greenery systems to be designed based on former fortification areas, city greenery, and natural environmental resources, which have been integral elements of these towns over many past centuries.
