The aim of this research was to understand how private sector natural capital investments could be increased and diversified in the Spey catchment. The focus of the study was on businesses that do not primarily manage land, but nevertheless rely on the Spey landscape, e.g. for their supply chain or to attract customers. Specifically, the study tried to answer four questions:
1. How do businesses currently invest in natural capital?
2. What motivates and hinders businesses to invest in natural capital?
3. Is there potential for coordinated business investment in natural...

A Green Infrastructure Plan of Llanquihue, which includes the Baquedano Wetland Park, was developed through the joint working of the Landscape Architecture Master Program Universidad de Chile and the NGO Legado Chile Fundatio. It is a response to several socio-ecological pressures created by urban living that were affecting ecosystems within the city boundaries. In 2016 both institutions called on an open dialogue with 300 members of the community, including residences, local authorities, the school community, regional services, representative of productive industries, scientists and...

Controlling and mitigating the heat island effect in Arará slum, northern Rio de Janeiro, based on the development and monitoring of green roofs, using epiphytes or lithophytes. Given the common uses of cement or metal, tiles required the development of specific techniques and materials to allow for the growth of vegetation while keeping the overall weight low for safety.

There were plans for a huge dam for hydro-electric energy production, mainly for export. The study was designed as a standard Cost-Benefit Analysis (CBA), including environmental costs and distributional impacts. Cost-benefit-analysis was used to assess the value of the project because it is a widely accepted framework and can combine diverse secondary data about the expected consequences. Despite time pressure and relatively poor data availability, conservative estimates about investment costs, likely returns and environmental damage (along with associated loss of natural assets and...

The objective of the LIFE-EnviFriendly project was to demonstrate low cost, nature based solutions that if used by all farmers within a watershed it will improve the water quality of the waters significantly.  The NbS used in this case was a riparian forest restoration coupled with a river bank erosion protection.

The Greater London Authority (GLA) participants in the BRIDGE FP7  project identified the primary planning goals for the Central Activities Zone (CAZ)[1] as to: (a) increase green space; (b) improve air quality; (c) reduce the UHI effect (heat island) and (d) prevent flash floods, with climate change adaptation and mitigation seen as a cross cutting issue.

London has a number of plans aimed at addressing these challenges, including:

• The Mayor’s London Plan in which two goals relate to urban green space and aim
