Developing a planting scheme with the support of the local engaged population. The creation of national institutions and laws that gave the support for the local activism focused on natural areas. In São Paulo, different groups are working to increase the biodiversity and tree cover in the city by planting small forest patches, locally known as pocket forests.

The act of planting per se is...

Nature-based solutions for improving well-being in urban areas in Sheffield, United Kingdom

This case study examines in particular the interface between four sets of plans and strategies, providing important context for further examination of meso- and micro-scale interventions covered in subsequent sections.

The Santiago Green Infrastructure Plan: towards a green infrastructure system

Inequity in distribution and quality of urban green infrastructure in Santiago

Developing a green infrastructure plan in Santiago as a shared territorial strategy and a means of unifying different stakeholders relevant for decision making and implementation at different spatial scales.

Heritage zone of Xochimilco: Tlahuac and Milpa alta, Mexico City. The importance of Nature-Based Solutions

Chinampa Atliacac harvest agrochemical-free products in Tláhuac. The chinampa is a cultivation method used by native indigenous groups to expand the territory in the lakes and lagoons of the Valley of Mexico, and they use them to grow flowers and vegetables.

Natural systems or nature based solution have been suggested and implemented in order to reduce...

Multisectoral and multiscale articulation for urban regeneration in Medellín and its Metropolitan Area

Medellin's accelerated growth has increased occupation of risk areas such as mountain slopes and has deepened problematics such as air pollution.

In response to the challenges arising from the urban expansion of Medellín and the close association with neighbouring municipalities, the Metropolitan Area of the Aburrá Valley (AMVA for its Spanish abbreviation) was established in 1980 as a regional public transportation and urban environmental authority. Within this context, the current city government, in co-ordination with other municipalities of the AMVA, focused its development plan (Plan de Desarrollo) priorities on the implementation of actions to improvethe urban environment, including nature-based interventions from the...
