Rasbiologiskt språkbruk i statens rättsprocess mot sameby : DN Debatt 2015-06-11
- 2015

Annan publikation (populärvet., debatt m.m.)abstract
- Statens hantering av forskningsresultat i rättsprocessen med Girjas sameby utgör ett hot mot Sverige som rättsstat och kunskapsnation. Åratal av svensk och internationell forskning underkänns och man använder ett språkbruk som skulle kunna vara hämtat från rasbiologins tid. Nu måste staten ta sitt ansvar och börja agera som en demokratisk rättsstat, skriver 59 forskare.

Large-scale productivity determinants of reindeer husbandry in Sweden
- 2009
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The productivity of the reindeer industry in the 51 herding districts in Sweden is affected by a large amount of factors on different geographical and temporal scales. Combinations of factors characterizing the environmental conditions for reindeer husbandry were identified and showed to be strongly correlated with variations in productivity, both between herding districts and between years. Productivities were described by estimated herd growth rates and carcass condition of slaughtered adult females and calves. These dependent productivity variables were related to the environmental independent variables using multiple linear regression and structural equation models (SEM). The independent variables were either considered as stable (e.g. topography, vegetation and infrastructure) or temporally changing (e.g. season lengths, weather events, disturbances and animal slaughter strategies). The most relevant independent variables identified were used in a cluster analysis to suggest a grouping of herding districts. Larger variation in productivity was found between herding districts than between years. Different variables were found to be important for between-district and within-district variations, respectively. Season lengths and animal densities were found noteworthy at both levels of variation. Other relevant variables found were ruggedness, snow condition, predicted harassing insect activity, supplementary feeding, proportion of calfs in slaughter and previous-year animal condition. Snow precipitation, predicted ice-crust formation and forage quality were presumed to be relevant for reindeer productivity, but were not found to have large impacts on productivity at this scale. These factors may have been neutralized or mitigated by husbandry measures, statistically included and thereby explained by other variables with strong effects on productivity, such as animal density variables. Several of the variables that were found to be important for productivity are correlated with climate and weather and therefore predicted to be central in a climatic change context

Reindeer husbandry in a climate change
- 2009
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- A questionnaire study on reindeer husbandry and climate change was performed to achieve the thoughts, concerns and conclusion of people with local knowledge working in the husbandry. The questionnaire consisted of climate scenario maps with weather variables relevant to the reindeer husbandry and was sent to 64 persons involved in reindeer herding from all parts of the Swedish reindeer herding area. They were asked to give personal reflections and predictions of the local conditions and how climate change would affect their local reindeer husbandry and prerequisites based on the given climate projections. In addition, there was room for the respondents to define local requirements for a continuously sustainable husbandry based on the presumed changes. The reindeer herding are was divided into 7 climate zones and a summary of the predicted climate changes for each area and excerpts from the questionnaire response and the climate scenario maps are presented in the poster

- Mat-forming lichens are important as food source for reindeer during the winter, and thus a vital resource to manage in reindeer husbandry. In this paper we suggest a method for monitoring of changes in lichen height with the purpose to early detect changes in lichen abundance in reindeer grazing areas. The method is intended for measuring geographically uniform lichen areas, evenly used for reindeer grazing. We analysed spatial variations in lichen height at the meter and 100 m scales, and calculated sample size requirements, and estimated effects of forest density and age, lichen moisture and lichen density on lichen height, and assessed the correspondence between lichen height and biomass. The variation in lichen height differed considerably between sites and, hence, the required sample size to detect a 5 mm change in lichen height with a power of 0.95 ranged from 200 to 2000, depending on the standard deviation of measured heights. Based on the autocorrelation in lichen height found between adjacent measurement points, a minimum distance of 4 m between measurement points is also recommended. Lichen height was significantly affected by lichen moisture, and the results suggest that this effect of moisture might vary with lichen density. Lichen height varied spatially within the study sites, and the spatial variations were partly caused by forest age and density. Thus, gradual changes in the forest characteristics are likely to alter the spatial variation in lichen height and it is therefore important to regularly re-evaluate the locations of measurement points within the monitored area. This study provides suggestions for a variable that could be used as an indicator of changes in the lichen resource, and aspects that should be considered when designing a monitoring program. The accuracy of detecting changes depends on the monitoring efforts, i.e. the number and distribution of measurement points and how often an area is monitored. In conclusion, our results indicate that measurements of lichen height have considerable potential for monitoring of changes in lichen resources within reindeer husbandry

Tidskriftsartikel (refereegranskat)abstract
- With complex common pool resources, it is important to balance the multitude of interests in order to generate a sustainable management regime. This is not the case in the northern parts of Sweden, where forest resources are used for different extractive purposes by forest companies and the reindeer herding industry. In many respects, the present situation represents a classic collective-action problem with a number of reasons why no cooperative behaviour might be expected. This article illuminates the relationship between the two industries in an historical, ecological and institutional perspective in order to explain the limited scope of coordinated action between the two actors. It also, through the use of collaborative learning techniques and scenario methods, explores the possibilities for the two industries to consider each other's needs and to identify strategies for co-existence and co-management. The testing of a broad range of scenarios among a selected group of stakeholders leads to the identification of possibilities for improving the management of the forest and lichen resource by changing institutional arrangements and improving coordination between the stakeholders.

Tidskriftsartikel (refereegranskat)abstract
- To evaluate the movement rates of semidomesticated reindeer (Rangifer tarandus tarandus) during the bare-ground season, we used successive GPS positions from 48 female reindeer. Data were collected during the summers of 2002 and 2003 in two Sámi reindeer herding districts in the Swedish mountains, Handölsdalen, and Sirges. The movement rates were analysed at different time periods: over the whole season, and over the sub-seasons spring, and early summer, mid summer and early autumn. Variation in movements were analysed in relation to vegetation type, altitude, terrain ruggedness, temperature, wind speed, and proximity to hiking trails. We hypothesised that the foraging quality and different weather conditions is an important factor in determining movement rates. We found that reindeer movement rates were similar between study areas and were dependent on vegetation type and on weather conditions. Studying the circadian movements, in mid summer period when daytime oestrid activity are expected to be high, the reindeer stayed at higher altitudes where food quality was low, but moved to low altitudes at night where the food quality was higher. Therefore, we suggest that oestrid activity forces the reindeer to stay in low-quality vegetation types. Reindeer movements were linked to disturbance in areas of intermediate human activity. We found that in Handölsdalen, where hikers are abundant, the movement rates of reindeer decreased closer to the trails whereas in Sirges, where hikers are less abundant, the movement rates of reindeer increased closer to the trails.
