Climate change: Motivation for taking measure to adapt

Journal article (peer-reviewed)abstract
- We tested two consequences of a currently influential theory based on the notion of seeing adaptations to climate change as local adjustments to deal with changing conditions within the constraints of the broader economic-social-political arrangements. The notion leaves no explicit role for the strength of personal beliefs in climate change and adaptive capacity. The consequences were: (i) adaptive action to climate change taken by an individual who is exposed to and sensitive to climate change is not influenced to a considerable degree by their strength of belief in climate change and (ii) adaptive action to climate change taken by an individual who is exposed to and sensitive to climate change is not influenced to a considerable degree by their strength of belief in an adaptive capacity. Data from a 2004 questionnaire of 1950 Swedish private individual forest owners, who were assumed exposed to and sensitive to climate change, were used. Strength of belief in climate change and adaptive capacities were found to be crucial factors for explaining observed differences in adaptation among Swedish forest owners. (C) 2008 Elsevier Ltd.

The story of phosphorus : Global food security and food for thought
- 2009
-
In: Global Environmental Change. - : Elsevier. - 0959-3780 .- 1872-9495. ; 19:2, s. 292-305
-
Journal article (peer-reviewed)abstract
- Food production requires application of fertilizers containing phosphorus, nitrogen and potassium on agricultural fields in order to sustain crop yields. However modern agriculture is dependent on phosphorus derived from phosphate rock, which is a non-renewable resource and current global reserves may be depleted in 50–100 years. While phosphorus demand is projected to increase, the expected global peak in phosphorus production is predicted to occur around 2030. The exact timing of peak phosphorus production might be disputed, however it is widely acknowledged within the fertilizer industry that the quality of remaining phosphate rock is decreasing and production costs are increasing. Yet future access to phosphorus receives little or no international attention. This paper puts forward the case for including long-term phosphorus scarcity on the priority agenda for global food security. Opportunities for recovering phosphorus and reducing demand are also addressed together with institutional challenges.

Murky water : Analyzing risk perception and stakeholder vulnerability related to sewage impacts in mangroves of East Africa
- 2009
-
In: Global Environmental Change. - Guildford, Surrey : Butterworth-Heinemann, publ. in cooperation with the United Nations University. - 0959-3780 .- 1872-9495. ; 19:2, s. 227-239
-
Journal article (peer-reviewed)abstract
- Coastal cities in East Africa are growing rapidly and consequently there is a rapid increase in urban sewage production, putting added pressure on already strained treatment systems. As a result, peri- urban mangroves are receiving extensive amounts of sewage but very little is know as to the ecological and societal consequences of this. However, UNEP among others advocate the use of low-cost, natural sewage treatment technology whenever possible and mangroves have been suggested as useful second stage biofilters. Because of the high resource dependency in many peri-urban coastal communities in East Africa, it is imperative to investigate potential societal impacts on local communities using sewage impacted peri-urban mangroves. Consequently this paper aims to characterize stakeholder groups currently affected by sewage impacted mangroves and thus also map vulnerabilities across local users in relation to future initiatives to use mangroves as biofilters along the East African coast. As risk perception is an important part of vulnerability, and risk perception related to sewage and pollution in an African setting has been little studied, we also aim to contribute baseline data on risk perception related to pollution across peri-urban populations in Kenya, Tanzania and Mozambique.

Earth System governmentality Reflections on science in the Anthropocene
- 2009
-
In: GLOBAL ENVIRONMENTAL CHANGE-HUMAN AND POLICY DIMENSIONS. - : Elsevier BV. - 0959-3780 .- 1872-9495. ; 19:1, s. 7-13
-
Journal article (peer-reviewed)abstract
- This paper examines Earth System Science as a novel approach to global environmental change research. Drawing upon Michel Foucaults governmentality concept, the paper opens up the Earth System metaphor to political analysis and asks what it does to our understanding of nature and society as a governable domain. We trace the scientific practices that have produced the Earth System as a thinkable analytical category back to the International Geophysical Year in 1957. We also identify the Anthropocene as a central and yet ambiguous system of thought for Earth System Science that harbours different strategies for sustainability in terms of (1) the persons over whom government is to be exercised; (2) the distribution of tasks and actions between authorities; and (3) contrasting ideals or principles for how government should be directed.

Dealing with drought : The challenge of using water system technologies to break dryland poverty traps
- 2008
-
In: Global environmental change. - : Elsevier BV. - 0959-3780. ; 18:4, s. 607-616
-
Journal article (peer-reviewed)abstract
- We explore strategies among farmers in semi-arid Tanzania to cope with drought, and investigate if access to a local supplemental irrigation system (the Ndiva system) can improve coping capacity. Results show high dependency on local ecosystem services when harvests fail, and indicate that farmers commonly exhaust asset holdings during droughts. Ndiva access did not have any direct effects on coping capacity, but seemed to have some indirect effects. Drawing on our findings we discuss the complexity of escaping persistent dryland poverty, and outline the circumstances under which small-scale water system technologies, such as Ndiva irrigation, may help.
