“…Se considera relevante que actores de escalas superiores actúen como avales de los acuerdos y la coordinación para la protección (Barriga et al, 2006), proveyendo así un reconocimiento institucional sobre la importancia del humedal (Moreno-Casasola et al, 2019). En este caso de estudio, el respaldo de actores regionales permitió al gobierno local acceder a herramientas que facilitan la sostenibilidad de los ecosistemas (Martínez et al, 2020), por ejemplo, apoyo técnico para evaluar el estado ecológico del humedal, tal como se aprecia en la Figura 7.…”

Wetlands are ecosystems that are disappearing, mainly due to urban and industrial activity and their vulnerability to the effects of climate change. In Chile, regulations and initiatives for their protection have been created, which are conditioned by the influences, interests and interrelationships of the players involved in the governance system. This research analyzed the case of the wetland located in Pichicuy, currently administrated by the Municipality of La Ligua. It researches in greater depth the role of local governments in the governance of wetland protection, considering the participation of the network of players from different spheres and territorial scales. Mixed methods of social research were used to analyze the influence, interests, types of relationship and centrality measures using the Analysis of Social Networks and the UCINET 6 platform. The local government of La Ligua performs, through its Environment Department, roles that are relevant for the governance of the wetland: (1) gaining political support to manage and implement actions about the wetland, (2) acting as an intermediary between the players from different spheres of society, and (3) leading alliances with higher-scale players. These roles are strengthened by the support and resources provided by the players of the network with high interest and influence in the protection of the wetland. However, there are challenges in municipal dynamics, for example, the need to more strongly attract and involve the Municipal Council, since it has a great influence on local government decisions. It is relevant to strengthen governance for the protection of wetlands in small and rural locations, for which the local government must play a very important role, for example, through institutional recognition of the wetland and facilitating the participation of players at a local scale.

“…In the last four decades, the central zone of Chile (CZC) has been affected by greatmagnitude earthquakes, followed by tsunamis (e.g., Algarrobo 1985 (8.0 Mw); Concepción 2010 (Mw 8.8); Illapel 2015 (Mw 8.4) [5]; ENSO El Niño-Niña (1997-1998; 1998-2000; 2015-2016)); hydro-meteorological events in 2006; 2013; 2015; 2017; and 2018 have frequently affected Chile's coasts, causing damage to infrastructure, loss of human lives, cessation of port operations, and shipwrecks [6]; the increase in the frequency and intensity of storms surged from 2015 to 2023 [7,8]. Anthropogenic interventions have occurred on wetlands, beaches, and dunes [9]. Coastal erosion is a hazard for cities and infrastructure built near the sea, on wetlands, beaches, and dunes [10].…”

“…Refugee migration and their settlement increase both populations and a spatial dimension. Urbanization has both positive and negative impacts depending on the scale of urbanization (e.g., Jehling & Hecht, 2021;Li et al, 2020;Martínez et al, 2020;Pham et al, 2019). However, how do pocket-based (camps) settlement and their numbers impact urbanization and vice-versa?…”

Urbanization needs to conceptualize beyond the city boundaries by exploring complex and interconnected interdependencies in regional key driving factors that can have tele-coupling effects during sudden shocks. Massive refugee settlement has a robust inter-linkage to the spatial and socio-ecological dynamics in local, regional contexts in both global south and North Countries. This study aims to explore the spatial dimension of urbanization in a regional transition context focusing on the newly built refugee settlement in the south-eastern coastal area of Bangladesh. For locational proximity and comparatively easy escape from Myanmar after domestic conflicts, over one million Rohingya have settled in the rural/forest area in Cox’s Bazar. Analysis of openly available global data products from historical built-up expansion from 1975 to 2021 suggests that refugee settlements impact spatial development intensity and population density dimensions, which have a transition (rural-to-urban) of a greater regional scale than local urbanization. Although our results from the expert-based key informant interviews have a broad agreement with the quantitative findings; however, the environmental, socio-economic, and cultural impacts are more local than findings from the geospatial analysis. Therefore, the local development policies need an urgent adjustment to comply with the local and regional balances in the above factors, along with international development actors may also need attentive measures in the policy formulation. Further investigations in scenario-based urbanization dynamics are required to avoid an urban desert initiated in the absence or relocation of refugee settlement. Similar kinds of studies may also be replicated even in prosperous global north countries in order to conceptualize the spatial transformative process of rapid migration influx on urbanization with innovative open data in the absence of up-to-date official datasets and adoptions of mixed approaches including related actors and policymakers.
