    Regulation and Protection of Urban Wetlands: A Comparative Analysis in Chile, Colombia, and Peru
    (Springer, 2024) Moschella, Paola; Rojas Quezada, Carolina Alejandra; Aldana-Domínguez, Juanita; Stamm, Caroline Andre; Velásquez, Carlos Javier; Capera, Ingrid
    Latin American countries have a set of legal instruments and public policies that contribute to the protection of urban wetlands against the pressure of city expansion that threatens their extent and quality. With the aim of discussing the role of public policies and regulations in the protection of urban wetlands, the situation in Chile, Colombia, and Peru is analyzed in a comparative manner. These countries are examples of diverse regulations and wetland biodiversity in urban environments. Legal instruments for environmental protection and conservation, spatial planning, and urban planning relevant to the management of urban wetlands are analyzed. In addition, advances in regulation and protection of urban wetlands are evaluated and contrasted based on national-level indicators. The lack of effective protection measures is demonstrated. The three countries have adhered to the Ramsar Convention to protect their wetlands and have established Ramsar sites; however, their existence does not stop the pressures and threats to the wetlands. It is identified that Peru has a larger surface area of Ramsar sites and that Colombia has the most extensive Ramsar urban wetland. It is highlighted that Chile has a recent urban wetlands law, while in Colombia and Peru the category of urban wetland does not exist in legislation. Meanwhile, in the protected natural areas, urban wetlands practically have no presence. Among the main weaknesses are the disarticulation between sectors and planning scales; in addition to outdated planning instruments regarding current challenges such as climate change, the water crisis, and the loss of biodiversity.

    Urban Wetland Losses and Land-Use Conservation Challenges in Three Latin American Cities
    (Springer, 2024) Aldana-Domínguez, Juanita; Rojas Quezada, Carolina Alejandra; Munizaga, Juan; Moschella, Paola; Stamm, Caroline Andre; Martínez, Carolina
    Wetlands are valuable and threatened ecosystems throughout the world. They are essential for the maintenance of life and ecological balance, in addition to providing a larger number of benefits to human societies. Wetlands reduce the risk of flooding by regulating the flow of water, being essential to reduce the impacts of climate change, especially along the coasts and coastal cities of the world. Urban growth poses a risk to wetlands in and around urban areas. In this work, we quantify the loss trends of wetlands in urban areas in three Latin American countries between the years 2002 and 2019. We selected as case studies the wetlands of Aconcagua in Chile, Ciénaga de Mallorquín in Colombia, and Pantanos de Villa in Peru. Through multitemporal analysis of Quickbird satellite imagery collections, we classify land covers at 2.5-m resolution and identify areas covered by wetland. We quantify the losses and gains of the wetland areas and the areas surrounding them. We found that the three wetlands analyzed lost area, confirming the worldwide trend of loss. The Ciénaga de Mallorquín wetland was the one that decreased the most due to coastal dynamics and urbanization. The Pantanos de Villa wetland reduced its area due to the increase in urban areas that grew filling the wetland under the pressure of informal settlements and beach condominiums. Lastly, the Aconcagua wetland was reduced due to the increase in grasslands together with the increase in bare soil, also affecting the beaches and dunes. In all three case studies, urban wetlands decreased due to urban growth. For this reason, we call attention to the urgency of improving urban planning to ensure the maintenance of these key ecosystems to ensure more sustainable and resilient cities, as proposed by Sustainable Development Goal 11.

    Urban Wetlands in Latin America: Protection, Conservation, Innovation, Restoration, and Community for Sustainable and Water Sensitive Cities
    (Springer Cham, 2024) Aldana-Domínguez, Juanita; Rojas Quezada, Carolina Alejandra; Munizaga, Juan; Moschella, Paola; Stamm, Caroline Andre; Martínez, Carolina; Velásquez, Carlos Javier; Capera, Ingrid; Falfán, Ina; Zambrano, Luis; Soto, Evelyn; Teutsch, Camila; Scheuch, Teresita; Fernández, Antonio; Briceño, Felipe; Vattuone Troncoso, Catalina de los Angeles; Domínguez, Juan Carlos; Riveros, Andrés; Pichunleo, Enzo; Rojas Quezada, Carolina Alejandra
    This book is about the contribution of urban wetlands in livable cities. Urban wetlands are very valuable blue-green infrastructure spaces for human settlements, yet they are disappearing as a result of urbanization. This phenomenon is worldwide, but is particularly intense in Latin America. Although international literature has made an effort to document the multiple ecosystem services provided by these ecosystems, such as water and air cleansing, flood mitigation and recreation, among others, we want to draw attention to the fact that the loss of urban wetlands affects the sustainability of cities and future generations. Therefore, and given the weakness of public policies implemented in the region for their protection, it is essential to highlight good practices, mechanisms and strategies aimed at Protection, Conservation, Innovation, Restoration, and work with the Community, all of this hand in hand with the 17 Sustainable Development Goals.The book offers a comprehensive coverage combining the need to protect and conserve urban wetlands from the pressures of urban growth, as well as highlighting successful experiences of regulation and of course applied research aimed at nature-based solution design for flood management and wastewater treatment, restoration areas, green infrastructure plans, as well as experiences of collective work with communities in contexts of political tensions for the defense of wetlands.
