Tidskriftsartikel (refereegranskat)abstract
- In this paper we analyse the requirements of bioproductive land in a future industrial so-ciety of 10 billion people, with average per capita economic standard comparable to that of the industrialized countries of today. Despite significantly more efficient technology, lowering demand for both energy and material per service delivered, requirement for food and material alone will call for a heavily increased demand for bioproductive land for use in agriculture and silviculture. Large areas of short rotation energy plantations may be biophysically possible, but will clearly compete for available bioproductive land with agriculture and silviculture, as well as with preservation of the world's biodiversity. Therefore, the notion that there exists large areas of surplus or degraded land, which, without coming in conflict with food production and preservation of biodiversity, can be used for large energy plantations has not fully taken into account possible increased de-mand for bioproductive land from global industrialization and raising of the global average economic standard.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The text in this book presents various system aspects on materials ows in society and nature and then mainly from a natural sciences and technical point of view. It is aiming at giving an overview of important material ows in society and in nature and their interactions in a sustainability perspective and the text is therefore of a more principal character. More examples and applications in specific sectors of society can be found in the other books of this series. Unfortunately, the examples and data presented in this book are exclusively from western countries. The documented and available studies on materials ows in the society and their connections to the environmental and resource problems are to an overwhelming majority describing western societies and this book has drawn from these studies.
