Abstract: Climate adaptation is an extremely relevant theme for landscape architecture. This article is based on 2 design studies. The first is our manifesto and regional study “Climate Park Green Heart”. This plan was originally developed in 2010 for the Innovation Network Ministry of Economics, Agriculture and Innovation. In this plan we propose to convert land reclamation sites and vulnerable peat areas into climate buffers that make the water system more resilient, reduce soil subsidence, protect against flooding and capture CO2 through peat restoration and thus help counteract the greenhouse effect. The climate buffers increase the diversity and attractiveness of the landscape for 8 million inhabitants. The second study focuses on Amstelland. This region is an attractive rural area immediately south of Amsterdam. The area is part of the Green Heart National Landscape. Regional design research Green Heart, Case Study Amstelland was carried out in 2019 on behalf of the Provincial Advisors on Spatial Quality of Nort Holland, South Holland and Utrecht. The Amstelland is a culturally and historically valuable open agricultural landscape in the Green Heart that penetrates the urban fabric of Amsterdam along the Amstel River. We have investigated 2 scenarios for this area: 1) How can we make the agricultural landscape sustainable and climate-proof and 2) what it means to convert this agricultural landscape into nature and to actively encourage peat growth. Both scenarios also have the objective of preserving the Amstelland as a valuable open space for the surrounding urban area for Amsterdam.
