Ecosystem-based adaptation (EbA) measures have been increasingly promoted in the literature, as well as in policies and practices, for their environmental and socio-economic co-benefits. The recent scientific literature has shown a growing interest to assess climate adaptation plans at the urban level, in recognition of the important role played by urban areas in addressing climate change challenges. However, little information is available on the combination of these two issues, i.e., the actual inclusion of EbA measures in climate adaptation plans at the urban level.

The design of efficient Green Infrastructure —GI— systems is a key issue to achieve sustainable development city planning goals in the twenty-first century. This study’s main contribution is the identification of potential GI elements to better align the environmental, social and economic perspectives in the GI design by including information about the use, activities, preferences and presence of people. To achieve this, user generated content from Location Based Social Network —LBSN— Foursquare is used as a complementary data source.

Blue-green infrastructure (BGI) is becoming a more popular means of dealing with climate change and climate change-related events. However, as the concept of BGI is relatively new, many urban and rural planners are unfamiliar with the barriers they may face during the lifecycle of a BGI project. As a result, some have been hesitant to adopt BGI solutions. The literature has unveiled many of the barriers that inhibit the successful development of BGI, however, this information has yet to be presented in a manner that allows for easy identification.

This new report by the PBL Netherlands Environmental Assessment Agency in collaboration with the Clingendael Institute and other Dutch research institutes points to pressure on security and migration arising from too little, too much or polluted water. Many integrated solutions are possible to divert this trend towards a sustainable and climate-resilient world.

Dans les villes en développement, les marchés fonciers et immobiliers sont en grande partie informels. Ils concernent les pauvres comme les classes moyennes. À Phnom Penh, l’analyse de la dynamique des marchés fonciers et immobiliers et des modes d’accès au logement dans les quartiers informels permet de mieux comprendre les tendances contradictoires des dynamiques en cours. Cette analyse peut alimenter la définition d’une politique de l’habitat destinée à réguler le marché foncier et immobilier et favoriser l’accès à la ville pour les populations pauvres.

Cette journée de réflexion a été consacrée à la sécurisation de l’accès au sol et à l’habitat dans les villes du Sud, et notamment aux marges de celles-ci, dans les quartiers dits précaires ou informels. Elle s’inscrit dans la continuité des débats initiés lors de la 3e conférence mondiale des Nations unies sur le logement et le développement urbain durable (Habitat III), qui s’est tenue à Quito en 2016.

Nearly 200 million Africans currently live in slums. Urban operations are one of the main tools for improving living conditions in informal settlements, where land tenure, housing, development and services largely function outside any official system. While progress has undoubtedly been made over the last decade, these operations have had mixed social, economic, urban and environmental impacts.

Today, the Coalition for Urban Transitions releases a new report ‘Seizing the Urban Opportunity’, which provides insights from six emerging economies on how national governments can recover from COVID-19, tackle the climate crisis and secure shared prosperity through cities. Launching as a call to action for national governments ahead of COP26 in Glasgow, it builds on the Coalition’s flagship 2019 report: Climate Emergency, Urban Opportunity.

US cities are at the forefront of the sustainable development challenge. They contain 80% of the country’s population, and therefore have the capacity to make or break SDG achievement (US Census Bureau 2016). But, while crucial to SDG attainment, they Executive Summary cannot accomplish this alone. While 80 percent of US residents live in urban areas, only 3 percent of land is urban; rural and urban areas are deeply interconnected (US Census Bureau 2016).

This 2019 SDG Index and Dashboards Report for European Cities (prototype version) provides an overview of the performance of 45 capital cities and large metropolitan areas on the Agenda 2030 and 17 Sustainable Development Goals (SDGs) adopted by global leaders in September 2015 at the UN Sustainable Development Summit.

The Sustainable Development Report 2019 – Mediterranean Countries Edition is a synthetic review of the fourth edition of the Sustainable Development Report 2019, including integrated contents and tables editing, specifically focusing on 23 Mediterranean countries. It was drafted by a team of experts of the University of Siena – Santa Chiara Lab, as hosting institution of the Sustainable Development Solutions Network for the Mediterranean Area (SDSN-Mediterranean), in an effort to raise awareness on the SDGs and foster the implementation of transformation strategies.

The rise of urban populations has rendered cities in both developed and developing countries vulnerable to poor health and diseases that are associated with urban living conditions and environments. Therefore, there is a growing consensus that while personal factors are critical in determining health, the urban environment exacerbates or mitigates health outcomes, and as such the solution for improving health outcomes in urban settings can be found in addressing socio-environmental factors that shape urban environments.
