Musselodling i Östersjön som miljöåtgärd : nya positiva data från tre pågående EU-projekt
- 2019
-
Rapport (populärvet., debatt m.m.)abstract
- Nya resultat visar att musselodlingar i Östersjön har en betydande potential att bidra till att minska övergödningen samtidigt som förutsättningar skapas för en cirkulär ekonomi/produktion. För att ta musselodling till nästa nivå krävs dels ytterligare förfining av den nya tekniken, men framförallt fler och i förlängningen också större odlingar samtidigt som vi måste vidareutveckla alla de initiativ som nu pågår hur näringen kan återanvändas i livsmedelssystemet på ett effektivt och ekonomiskt lönsamt sätt.

Tidskriftsartikel (refereegranskat)abstract
- The Baltic Sea Action Plan (BSAP) requires tools to simulate effects and costs of various nutrient abatement strategies. Hierarchically connected databases and models of the entire catchment have been created to allow decision makers to view scenarios via the decision support system NEST. Increased intensity in agriculture in transient countries would result in increased nutrient loads to the Baltic Sea, particularly from Poland, the Baltic States, and Russia. Nutrient retentions are high, which means that the nutrient reduction goals of 135 000 tons N and 15 000 tons P, as formulated in the BSAP from 2007, correspond to a reduction in nutrient loadings to watersheds by 675 000 tons N and 158 000 tons P. A cost-minimization model was used to allocate nutrient reductions to measures and countries where the costs for reducing loads are low. The minimum annual cost to meet BSAP basin targets is estimated to 4.7 billion a,not sign.

Optimal management of two ecologically interacting deer speciesreality matters, beliefs don't
- 2017
-
Ingår i: Natural Resource Modeling. - : John Wiley & Sons. - 0890-8575 .- 1939-7445. ; 30:4
-
Tidskriftsartikel (refereegranskat)abstract
- The aim of this paper is to analyze the optimal management of two ecologically interdependent, competing species, roe deer (Capreolus capreolus) and fallow deer (Dama dama). To this end, we develop a numerical stage-structured model, accounting for species-specific life history characteristics, gender, and stage-specific hunting values. Two contrasting management regimes are considered: optimal joint management of the two species and management where the decision maker is ignorant about interspecific competition. Results from our case study show that the presence of interspecific competition reduces roe deer population size and harvest by 30% and 47%, respectively, and reduces the net present value by 9%. High interspecific competition could lead to the exclusion of the roe deer from the area. In contrast, ignorance about the level and consequences of interspecific competition has no impact on harvest decisions and revenues. The explanation is the higher hunting benefits for fallow deer. Summary for Managers Wildlife managers need bioeconomic models for decisions on ecologically interdependent species. This study investigates optimal joint management of roe and fallow deer when the fallow deer exerts a negative impact on roe deer due to interspecific competition. Results show that interspecific competition reduces the net present value of hunting at the study site by 9%. Regulations will not increase the net present value of hunting in a situation where the manager is ignorant of interspecific competition.

Lokale matprodukter, kundepreferanser og biologisk kulturarv : Oppsummering av en kundeundersøkelse i Gävleborgs län, Sverige og i Trøndelag Fylke, Norge
- 2020
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Denne undersøkelsen er gjennomført innenfor rammen for Interreg-prosjektet «Biologisk kulturarvsom bærekraftig verdiskaper». Prosjektet har fokusert på det potensialet som småskala produsenterhar i å synliggjøre de natur- og kulturverdiene som er koblet denne typen matproduksjon.Forbrukerundersøkelsen som presenteres i denne rapporten ble gjennomført ved to utsalgssteder iSverige og to i Norge. I Sverige foregikk spørreundersøkelsen i Gävleborgs län, ved matfestivalenMoläta i Järvsö og ved setra Svedbovallen like utenfor Järvsö. I Norge ble den samme undersøkelsengjennomført i Trøndelag, ved Eggjenseteren i Snåsa og ved Mathallen Smak og Behag i Oppdal.Undersøkelsen ble gjennomført som en kombinasjon av spørreskjema og oppfølgende intervju. Itillegg er også resultater fra en pilotstudie ved Gregoriemarknaden i Sverige diskutert i rapporten.Forbrukerundersøkelsen fokuserer på fire hovedtemaer: a) hvordan informanten/kunden ser på dennetype bedrifter (företag) og hva de setter pris på ved besøket, b) hva kunden assosierer med det å handleslike lokale matprodukter, c) hvilke naturverdier og biologisk kulturarv de assosierer slike produktermed, d) hvilken bakgrunn kunden/informanten har.Omtrent halvparten av informantene i denne undersøkelsen svarer at de kjenner til selve begrepet«biologisk kulturarv». I og med at koblingen mellom lokale matprodukter og natur- og kulturarv ikkeer tydelig for alle kunder, bør det ligge et potensial i å formidle denne kunnskapen, slik at den kanbidra både til å styrke økonomien og bærekraften til virksomhetene. Resultatene viser også at mangeav kundene verdsetter den opplevelsen det er å besøke slike utsalgssteder. Dette inkluderer blantannet opplevelser knyttet frivillig arbeid (volonärer), drikke kaffe, oppleve spesielle landskap og hakontakt med dyr. Det sosiale samværet ved å besøke matfestivalen, markedet, setra eller det lokaleutsalgsstedet er også noe som påvirker kundenes opplevelse av produktene. Mange avinformantene/kundene i denne undersøkelsen viste seg å ha en indirekte/historisk geografisktilknytning til utsalgsstedet. Resultatene viser derfor at det kan være viktig å henvende seg tilutflyttere, hytteeiere og andre lokale/regionale turister/turistaktører for å danne seg et godtkundegrunnlag både for produktene og opplevelsene som tilbys.Våre resultater viser at salget av lokale matprodukter må anses å være en del av denhelhetsopplevelsen som tilbys. Produktene, til sammen med opplevelsene og aktivitetene må derforsees på som en pakkeløsning som kundene er villige til å betale for. Småskala matprodusenter børderfor sette fokus på helheten og ikke bare fokusere på kvaliteten til matproduktene.

Dietary reforms in the Baltic and East Central Europe, ca 1850–1950
- 2022
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- In this special section, the histories of dietary reform have been approached and explored from different perspectives. The essays weave together threads of the history of dietary advice and nutritional standards with social history, women’s history and food history, covering the elements of life reform and women’s movements, the establishment of communist food ideology, the development of modern food safety and food security, etc. Three peer-reviewed articles focusing on the case studies of Estonia, Bulgaria and the Russian empire are built on previously untapped sources and offer original perspectives on the topic. As the contributions suggest, the entangled histories of dietary reform efforts proved to be a valuable and novel prism through which to study the region and the history of Europe in general.

Economics of wildlife management-an overview
- 2018
-
Ingår i: European Journal of Wildlife Research. - : Springer. - 1612-4642 .- 1439-0574. ; 64:2
-
Forskningsöversikt (refereegranskat)abstract
- This study makes an explorative overview on two main research topics in economics of wildlife management: determination of population sizes and policy design. The results point out a large and comprehensive research on each of these issues, in particular on the estimation of values and costs of wildlife, where this information is necessary for the determination of population size. A drawback is that most of the value and cost studies do not relate their estimates to wildlife population size, which limits their usability for efficient policy design. Most valuation studies estimate the recreational value of hunting, which can range between 13 and 545 USD/hunting day (in 2013 prices), and two thirds of the included studies have been applied to wildlife in the USA. A majority of the studies on the costs of wildlife management calculate losses from carnivore predation on livestock and ungulate damage to crops, while a few consider dispersal of diseases and the cost of traffic collisions. Unlike valuation studies, several of the cost estimates apply to wildlife in developing and emerging economies. With respect to policy design the literature, which is mainly theoretical, suggests economic incentives for conflict resolution, where those suffering from wildlife damages are compensated for their losses. However, there are some issues which remain to be addressed by economists: relating costs and benefits to wildlife populations; estimating values and costs of wildlife in developing countries; evaluating wildlife policies in practice; addressing implications of uncertainty in population size, costs, and benefits for policy design; and estimating transaction costs for implementation and enforcement of wildlife policies.

The impact of climate information on milk demand : Evidence from a field experiment
- 2016
-
Ingår i: Food Policy. - : Elsevier BV. - 0306-9192 .- 1873-5657. ; 58, s. 14-23
-
Tidskriftsartikel (refereegranskat)abstract
- It has been suggested that carbon labelling of food, on voluntary or non-voluntary basis, could reduce emissions of greenhouse gases. However, there is limited empirical evidence on the influence of such labels on consumer purchases. The purpose of this study was to investigate whether voluntary carbon labelling affects the demand for milk. A randomized field experiment was conducted in 17 retail stores in Sweden, where a sign provided consumers with qualitative information about the carbon impact of climate-certified milk. The results suggest that the sign increased the demand for the climate-certified milk by approximately 6-8%, and the result is robust to alternative model specifications. The effect is entirely driven by large stores, such as supermarkets. We find no statistically significant impact on total milk sales, and the dataset is too small to verify the consequences for other milk brands. The effect on the demand for the labelled milk is short-lived.

Spatio-Temporal Analysis of Game Harvests in Sweden
- 2023
-
Ingår i: Environmental and Resource Economics. - : Springer. - 0924-6460 .- 1573-1502. ; 85, s. 385-408
-
Tidskriftsartikel (refereegranskat)abstract
- The benefits and costs of wildlife are contingent on the spatial overlap of animal populations with economic and recreational human activities. By using a production function approach with dynamic spatial panel data models, we analyze the effects of human hunting and carnivore predation pressure on the value of ungulate game harvests. The results show evidence of dynamic spatial dependence in the harvests of roe deer and wild boar, but not in those of moose, which is likely explained by the presence of harvesting quotas for the latter. Results suggest the impact of lynx on roe deer harvesting values is reduced by 75% when spatial effects are taken into account. The spatial analysis confirms that policymakers’ aim to reduce wild boar populations through increased hunting has been successful, an effect that was only visible when considering spatial effects.

The Impact of Water Quality Management Policies on Innovation in Nitrogen and Phosphorus Technology
- 2021
-
Ingår i: Water Economics and Policy. - : World Scientific. - 2382-624X .- 2382-6258. ; 7:1
-
Tidskriftsartikel (refereegranskat)abstract
- The purpose of this study is to examine the effects on innovation of environmental regulations aimed at reducing eutrophication. We focus on innovations in nitrogen and phosphorus management technology in the wastewater treatment sector and the agricultural sector. Patent data from Sweden over a 50-year period is used as a measure of innovation. We estimate a negative binomial regression model in a reduced form and by the use of control-functions, taking into account environmental regulation as well as more general determinants of innovation. Our results suggest that increased regulation has induced innovation in the wastewater treatment sector, both in the long and short run. The short-run effect was estimated to 40-70% in the years immediately following the introduction of new environmental regulations. A corresponding effect could not be identified in the agricultural sector. The difference between the sectors is likely explained by differences in policy design, where performance standards are applied in the wastewater sector, while design standards and technology-specific subsidies dominate in the agricultural sector.

Heterogeneous impacts of large carnivores on hunting lease prices
- 2021
-
Ingår i: Land use policy. - : Elsevier. - 0264-8377 .- 1873-5754. ; 101
-
Tidskriftsartikel (refereegranskat)abstract
- Notwithstanding their crucial role in ecosystem functionality, large carnivores generally entail economic costs to hunters due to competition for the same prey. This cost could potentially vary depending on carnivore density and the game hunting values at stake. We estimate a hedonic price model applying the unconditional quantile regression method in order to investigate the impact of large carnivores along the distribution of hunting lease prices in Sweden. We compare these impacts with those obtained from conditional quantile regressions, as well as from ordinary least squares estimations. Based on the unconditional quantile estimates, our results indicate that wolf, lynx and bear can exert a negatively significant effect in the middle range of the outcome distribution, while no significant impact is found in the lower quantiles. For the statistically significant quantiles, the average marginal implicit price of an additional wolf territory in the study area is around 3.35 million Swedish kronor (SEK) per year, namely 358 thousand Euros (EUR). This corresponds to an annual reduction in the mean hunting lease price per hectare by 21% in the municipality where the territory is established. Similarly, an additional lynx family group entails an average marginal implicit price of SEK 3.55 million (EUR 379 thousand) per year, and an additional brown bear individual entails an average marginal implicit price of nearly SEK 110 thousand (EUR 11.6 thousand) per year. The corresponding impact on the mean hunting lease price per hectare is a reduction by 22.4% and 0.6% for an additional lynx family group and an additional brown bear individual, respectively, in the municipality where the establishment occurs. Results can be useful for policies targeting the spatial distribution of large carnivores. © 2020 The Authors
