“…The vulnerability of urban/peri-urban wetlands is also expressed in the voice of the executive director of the United Nations Environmental Program, Achim Steiner at the United Nations conference, Hyderabad, India in 2012. He expressed that 50% of wetlands in the world have been damaged during the last 100 years and recommended major land policy reforms for urban/peri-urban wetlands conservation 15 .…”

The loss of peri-urban wetlands is a major side effect of urbanization in India in recent days. Timely and proper assessment of wetland area change is essential for the conservation of wetlands. This study follows the integrated way of the peri-urban wetland degradation assessment in the case of medium and small-size urban agglomerations with a special focus on Chatra Wetland. Analysis of land-use and land cover (LULC) maps of the past 28 years shows a decrease of 60% area of the wetland including marshy land. This has reduced the ecosystem services value by about 71.90% over the period 1991–2018. From this end, The Land Change Modeler of IDRISI TerrSet using the combination of MLPNN and Markov Chain has been used to predict the LULC map of this region. The scenario-based modeling following the LULC conversion and nine explanatory variables suggests the complete loss of this wetland by 2045. However, the authors have also tried to present a future LULC pattern of this region based on an environmental perspective. This proposed map suggests possible areas for built-up expansion on the western side of the city without significantly affecting the environment.

“…In wetland change analyses, researchers have identified some implications of wetland landscape pattern changes due to urbanization [86,87]. There is evidence that environmental degradation is very much related to economic growth, as reflected particularly in per capita income [88].…”

Impacts of Urbanization on the Muthurajawela Marsh and Negombo Lagoon, Sri Lanka: Implications for Landscape Planning towards a Sustainable Urban Wetland Ecosystem

Urban wetland ecosystems (UWEs) play important social and ecological roles but are often adversely affected by urban landscape transformations. Spatio-temporal analyses to gain insights into the trajectories of landscape changes in these ecosystems are needed for better landscape planning towards sustainable UWEs. In this study, we examined the impacts of urbanization on the Muthurajawela Marsh and Negombo Lagoon (MMNL), an important UWE in Sri Lanka that provides valuable ecosystem services. We used remote sensing data to detect changes in the land use/cover (LUC) of the MMNL over a two-decade period (1997–2017) and spatial metrics to characterize changes in landscape composition and configuration. The results revealed that the spatial and socio-economic elements of rapid urbanization of the MMNL had been the main driver of transformation of its natural environment over the past 20 years. This is indicated by a substantial expansion of settlements (+68%) and a considerable decrease of marshland and mangrove cover (−41% and −21%, respectively). A statistical analysis revealed a significant relationship between the change in population density and the loss of wetland due to settlement expansion at the Grama Niladhari division level (n = 99) (where wetland includes marshland, mangrove, and water) (1997–2007: R2 = 0.435, p = 0.000; 2007–2017: R2 = 0.343, p = 0.000). The findings also revealed that most of the observed LUC changes occurred in areas close to roads and growth nodes (viz. Negombo, Ja-Ela, Wattala, and Katana), which resulted in both landscape fragmentation and infill urban expansion. We conclude that, in order to ensure the sustainability of the MMNL, there is an urgent need for forward-looking landscape and urban planning to promote environmentally conscious urban development in the area which is a highly valuable UWE.

“…The Philippines is a country with significant ecological issues and faces increasing challenges from climate change, including rising sea levels, increased risks of floods, heat waves, and other associated weather-related events [18][19][20]. It has one of the highest population densities in the region, combined with a low gross domestic product (GDP) [21].…”

Of the significant foreign investment by Japanese multinationals within South-East Asia, the Philippines is a key recipient and location for the establishment of subsidiaries. While foreign investment is thought to bring significant benefits to host nations, the Philippines is considered ecologically vulnerable with extensive pollution and environmental challenges. Within national contexts of this nature, debates ensue about manufacturing multinational enterprises using emerging markets or developing nations as pollution havens when their environmental regulations are less stringent than those of the home nation. This study adopts a case study approach to explore the behaviour of Japanese multinationals operating in the Philippines with respect to environmental regulations. The study’s findings indicate that the firms demonstrated environmental management practices at a level beyond requirements set by local laws and regulations, with supplementary benefits to the surrounding local communities. These results indicate that the Philippines’ environmental regulations could be strengthened or tightened up with little negative impact on the investment of Japanese manufacturing multinational enterprises. With scant research conducted at the organisational level, our research findings contribute to a multinational management perspective on pollution haven/halo research, providing an additional dimension alongside the macroeconomic and large-scale environmental effects.
