Land parsimony practices, comparative trends and outlook

Mise à jour le 13 April 2026

The French legislator established the target of Zero Net Artificialization (ZNA) in the law 2021-1104 on combating climate change and strengthening resilience to its effects (known as the “Climate and Resilience Law”)1 on the basis that land is first and foremost an organic part of the earth and only secondarily a resource to be used. This move institutes a national land parsimony objective which furthers the goal of protecting biodiversity and of conserving land by combating the conversion of natural, agricultural and forest areas to artificial surfaces. ZNA introduces into French law a correlation between land challenges and development practices under a wide-ranging climate policy which includes a systemic view of anthropogenic responsibilities in relation to climate change (Le Rouzic, 2022; Ménard et al, 2021).

La Fabrique de la Cité has published many papers on this topic in recent years2. What links are there between ZNA and the much older ideal of parsimonious land use? Is ZNA a specifically French planning practice? As French regional and inter-municipal authorities are currently transposing the implementing decrees and this is causing many tensions, a look at what other countries are doing provides some perspective and places parsimonious land use within a more comprehensive consideration of the challenges as they are raised and addressed in other countries or regions of the world. In conjunction with a position paper published in September 2023 by the French Senate on policies to reduce land take in Germany, Spain, Italy and the Netherlands 3, this author’s note by La Fabrique de la Cité will start by providing a brief overview of long-standing debates on parsimonious land use. It will then analyze its uptake by the European Union, then by the United Kingdom and Switzerland (two non-EU countries) and lastly by Japan, which has a complex non-European land parsimony model.
