Herbivore impact on the Swedish forest has under a long time been a common subject of debate. There are many different opinions depending on what direction the forest owner has with his/her forest. Populations of moose and roe deer have increased significantly in Sweden during the last decades. The purpose of this study is to get a full picture of the herbivore impact on the regeneration areas. The field work was done once a year for seven years (1999?2005).

Sweden has today the highest moose (Alces alces) population in the world. The population has been very high since the late seventies and in the beginning of the eighties there was a big ?moose explosion?. The main food source for moose during the winter is young pine (Pinus sylvestris) and birch (Betula spp.). The high moose population has therefore lead to high damage on pine forests over big areas.

Burkina Faso as well as most sub-Saharan African countries struggle with providing food for a fast growing population. The dominating farming system is agroforestry parklands. Agroforestry parklands can broadly be defined as areas where scattered trees occur on farmlands as a result of selective clearing. The presence of trees in crop fields may in the long term have a positive effect on the production of annual crops. It is commonly discussed, but not proven, that the presence of trees leads to increased groundwater recharge due to higher infiltration capacity of the soil.

SammanfattningBakgrund Att minska matsvinnet är en viktig del i arbetet mot att nå en hållbar utveckling. Utsläpp av växthusgaser och övergödning sker i alla produktionsled i livsmedelskedjan från producent till konsument och utgör en negativ klimatpåverkan. Livsmedelsbutiker har en betydelsefull roll eftersom de hanterar stora mängder varor och tillhandahåller mat till många hushåll. Forskning finns om typ och omfattning av matsvinn slänger men få studier har belyst hur chefer och personal i livsmedelsbutik upplever och tänker kring ämnet.Syfte Syftet var att undersöka upplevelser och tankar kring matsvinn hos butikschefer samt anställda i livsmedelsbutiker.Metod Studien genomfördes som en kvalitativ studie där butikschefer och anställda vid åtta livsmedelsbutiker intervjuades. Datamaterialet transkriberades och analyserades därefter med kvalitativ innehållsanalys enligt Graneheim och Lundman.Resultat ?Matsvinn sågs som ett problemområde som deltagarna upplevde svårt att motverka.

The aim of this paper was to study incoming complaints to The County Administrative Board in Västra Götaland during 2011 and examine if it was possible to see a connection between warranted and unwarranted complaints and informer, animal species and type of inadequate. In Västra Götaland, a complaint is classified as warranted if the inspection leads to a reprimand, whether it regards what was reported or not. Data were collected during three weeks through The County Administrative Board´s record system Platina and a total of 456 complaints were studied. The parameter ?complainant? was categorized into four groups according to The County Administrative Boards own division; public with the subgroups anonymous and non-anonymous, animal health staff and others.

Hunger is a problem in some parts of the world (www, FAO 1, 2012). The lack of food is often a result of insufficient knowledge in soil fertility management (Röing de Nowina, 2012). Ongoing hunger and malnourishment are quite prevalent in Sub-Saharan Africa and are often combined with poverty (www, FAO 1, 2012). Farming is the most common occupation in this area and the farms are often small-scale farms with subsistence crops and a few cattle. The farmers who operate these small-scale farms are economically a weak group.

Den rådande klimatsituationen utgör, på grund av föroreningar i naturen, ett hot mot jordens fortlevnad, det kan främst påvisas genom de klimatförändringar som blir allt mer tydliga i världen. Samhällets negativa påverkan på jordens klimat sätter press på samhällsaktörer, varav en av dem är handelssektorn. Livsmedelsbranschen är den aktör som idag arbetar mest med ansvarsfullt företagande. Fokus läggs främst på ekologiska produkter, miljömärkningar samt energieffektivt arbete.Trots satsningar på ekologiska livsmedelsalternativ samt egna märkesvaror med ekologisk inriktning råder idag kunskapsbrist bland konsumenter. Den finansiella aspekten utgör, tillsammans med tid- och bekvämlighetsaspekter, de huvudsakliga påverkansfaktorerna på konsumenters medvetna och omedvetna beteende.

Sigill Quality Systems has been certifying beef since the autumn of 2006 using the brand name label Swedish Sigill. IP Sigill (the certifying system for integrated production) encompasses the values: animal ethics, food safety, free range and environmental concerns. Product quality is not yet one of these values, and there is a variation in the quality of Swedish beef. Swedish Sigill wanted to investigate the factors that influence product quality, review which of the present regulations that have an influence on product quality and formulate new regulations with the purpose of enhancing the product quality (sensorial, technological and nutritional quality). A survey of quality parameters and factors that influence product quality was done in order to establish a scientific foundation to work from.

Abstract The global average temperature has increased by 0,74°C over the last 100 years. Most probably, the explanation is due to increasing use of fossil fuels and the agricultural expansion of land use. The new life stile of mankind leads to increasing concentrations of greenhouse gases in the atmosphere. Food consumption contributes with approximately a quarter of the total greenhouse gas emission per person and year, why it is an important task to reduce these. The aim of this work is to quantify energy use and greenhouse gas emissions for (Swedish) herbs produced in Swedish greenhouses. The study is based on a LCA (Life Cycle Assessment) and collected data from participating companies producing herbs in pots.

Within agriculture it is important to optimize the use of nitrogen, not only from an economic point of view but also to minimize damage to the environment. This can sometimes be difficult, especially within organic farming. Organic farmers are using increasing amounts of waste products from the food industry to cover their nitrogen needs. These different organic fertilizers release nitrogen at different rates and under specific soil conditions. Because of this, it would be beneficial to have a standardized method to measure the amount and rate of nitrogen mineralization from organic fertilizers. This project contributes to this knowledge by investigating whether relatively simple and repeatable laboratory methods can be used to estimate the nitrogen fertilizer value of organic fertilizers.

Aggression between laboratory mice is a common problem and can result in welfare issues such as mice hurting or killing each other and also stress. Swedish laws and regulations clearly states that mice must be housed with a companion due to their natural social structure. Many studies have investigated the effect off enrichment, group size, cage size and other potential changes in in their environment on the occurrence of aggression. Even with these changes aggression can exist and therefore a new solution was tested in this paper. The proposed solution was to house an intact mouse with a castrated one and thus fulfill laws and regulations while still maintaining the physiology of one of the mice for the purpose of medical experiments.

Increasing the use of biofuels is an important part of achieving the EU?s target of 10 percent renewable energy in the transport sector. However, the competition between biofuels and food production is an ongoing concern. Also, several studies have indicated a significantly higher climate impact than was earlier estimated, due to emissions from land use. In Sweden, both the use and production of biofuels from crops have increased substantially during the last decade. The purpose of this project is first to present an overview of the Swedish land use in all sectors.

Subclinical mastitis (SCM) is a well-known problem in the dairy sector, where it causes severe economic losses mainly due to reduced milk production. This is a problem not only in the western world but also in developing countries. Surveys from different developing countries have shown a SCM prevalence of 52.4 ? 88.6 % at cow level and 26.7 ? 63.2 % at quarter-level. To combat mastitis is important to optimize the milk production of the cow.

Composting is a process in which organic matter is mineralized by microorganisms. In January 2005 landfilling of organic waste was prohibited in Sweden. With this prohibition composting has become an important alternative to handle the produced organic wastes. One problem with continuous small-scale composting is the production of organic acids that will inhibit a further composting process. The aim of these theses was to study what effects temperature and dry matter content had on the production of organics acids, and what effect the organic acids had on the mineralisation of the substrate as well as the stability during storage of the product.

The different characteristics of many food products, such as aroma and texture, changes during storage time and become undesirable. The reason is instabilities within the product which become prominent as the product ages. These changes in characteristics are quality losses caused by changes in the product?s intrinsic and extrinsic environment. The stability in UHT-milk and beverages similar to it have been studied in the past decades and a certain focus have been on age gelation which is a common defect in these type of products.
