Introducing nature-based solutions into urban policy – facts and gaps. Case study of Poznań

Peer-reviewed publication
Mai, 2019
Global

Cities often don’t appreciate the benefits of green infrastructure (GI) enough. To recognise the extent to which green infrastructure and nature-based solutions (NbS) are present in the urban policy, we conducted a review of planning, strategic and programming documents of Poznań City as a Case Study.

Working on the boundaries—How do science use and interpret the nature-based solution concept?

Peer-reviewed publication
Décembre, 2019
Global

Nature-based solutions (NBS) is the latest contribution to the green concept family. NBS is defined as actions based in nature addressing societal challenges. In this study, we lean on the concept boundary object, broken down into three analytical categories: use, core ideas and granularities, to explore the cohesive and fragmenting powers of the NBS concept, and discuss its future role in green space governance. The study is based on a structured, qualitative review of 112 scientific peer-reviewed publications that use the term NBS.

Ecosystem-based adaptation in cities: An analysis of European urban climate adaptation plans

Peer-reviewed publication
Décembre, 2015
Europe

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.

Green infrastructure planning: Unveiling meaningful spaces through Foursquare users’ preferences

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.

Barrier identification framework for the implementation of blue and green infrastructures

Peer-reviewed publication
Novembre, 2020
Global

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.

The geography of future water challenges

Mai, 2018
Global

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.

Afrique

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.

2019 US Cities Sustainable Development Report

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).
