ABSTRACT
Values play a significant role in decision-making, especially regarding nature. Decisions impact people and nature in complex ways and understanding which values are prioritised, and which are left out is an important task for improving the equity and effectiveness of decision-making. Based on work done for the IPBES Values Assessment, this paper develops a framework to support analyses of how decision-making influences nature as well as whose values get prioritised. The framework is used to analyse key areas of environmental policy: a) the present model for nature protection in market economies, b) the role of valuation in bringing nature values into decisions, and c) values embedded in environmental policy instruments, exemplified by protected areas for nature conservation and payments for ecosystem services. The analyses show that environmental policies have been established as mere additions to decision-making structures that foster economic expansion, which undermines a wide range of nature's values. Moreover, environmental policies themselves are also focused on a limited set of nature's diverse values. This article is part of the theme issue 'Bringing nature into decision-making'.

The frequency of sister-chromatid exchange (SCE) was examined in bone-marrow cells of 21-day-old Wistar rats malnourished during lactation and well-nourished controls of the same age. Malnutrition was obtained by increasing the litter size to 15 pups per mother. SCE were scored in 25 consecutive second-division metaphases in the femoral bone marrow cells from each animal. The average SCE in the malnourished animals was significantly higher than in the control group (p less than 0.01). The distribution of SCE per mitosis was also significantly higher in the malnourished animals (p less than 0.001). These results indicate that malnutrition per se during early life can increase SCE in the bone marrow of experimental animals.
