Hur hushållas det med mark och vatten? en studie av tillämpningen av hushållningsbestämmelserna i 3 och 4 kap MB

The national spatial planning guidelines and the subsequent legal regulation in the Natural Resources Act and the Environmental Code has been a part of the Swedish planning system for almost 40 years. In the recent years, critics have claimed that the regulations are outdated and does not work the way it was intended. This paper examines closer why it is perceived that the regulations does not work, with a focus on how the national interests are managed in the municipal planning. Why is the national interests not applied in the municipal planning as intended? Is the error in the system or in the implementation of it? The aim of this essay is to study the gap between theory and practice by studying how the land management provisions in the Environmental Code is applied in five selected municipalities.

Ett gårdsbesök : ger besöket någon kunskap om mjölkproduktion?

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Prästgårdsträdgårdar : barndomsskildringar från 14 prästgårdsträdgårdar i Växjö stift

Few rectory gardens are today remaining in their former design and the cultural heritage that they represent are disappearing. Since 1987-88 the parishes are no longer bound to keep housing for their priests, which means that they, for economical reasons, are starting to sell their rectories. With this in mind, a group of people, growing up in rectories in Småland and Öland between the 1930th and 1950th, formed an interest group to save the memory of their rectory gardens. On the basis of their memories, they have written a couple of descriptions of the rectories, which describe the gardens content, design and the life they once lived there. With this compilation of the 14 rectory gardens I want to keep the memory of them and create a ground for future work in this field. Historically the rectory gardens played an important roll as patterns and examples in the countryside.

Inhysningssystem för kalvar och ungdjur i större besättningar :

In Sweden, there has been a continuous increase in the volume of housing construction for dairy cattle. Since 2004, the number of new, rebuilt and extended dairy cow houses undergoing preliminary inspection by the authorities has grown. The livestock farms have mostly focused on cow units instead of calf and heifer sheds; which has led to a need for information in this area. The purpose of the study was to improve advisors? knowledge about bovine building construction and function; to enable them to provide more qualified advice to conventional and organic milk producers who sustain larger herds.

Commercial thinning and its potential for contribution to the timber supply in British Columbia?s Interior forests : a look at Finnish and Swedish forest practices and their applicability in British Columbia?s Interior forests

Thinning is the partial removal of trees in a forest stand prior to final harvest. The term can be divided in pre-commercial thinning where little if any volume is removed from the stand and commercial thinning where removals are intended to provide a positive economic result. From a silvicultural point of view, the goal of thinning is to enhance future crop tree quality by removing low-quality stems and providing sufficient space for the accelerated development of retained ones (Huuskonen & Hynynen, 2006). The goals of this study was to see if commercial thinning could positively affect the short and medium term timber supply (MTTS) in the Interior regions of British Columbia (BC), and whether or not Scandinavian forestry practices could be adopted in the BC context. The mountain pine beetle (Dendroctonus ponderosae Hopkins) has created significant forest planning problems in BC. The annual allowable cut (AAC) was raised to capture beetle-killed timber while still merchantable.

Reningseffekt i dämd dagvattentunnel i Märsta, Sigtuna kommun : Pollutant removal in a dammed stormwater tunnel in Märsta, Sigtuna municipality

Det vatten som avrinner från hårdgjorda ytor, så kallat dagvatten, innehåller ofta en mängd olika föroreningar, så som tungmetaller och näringsämnen, som kan göra stor skada om vattnet inte renas innan det når recipienten. Ett vanligt sätt att rena detta vatten är genom öppna system, som dammar och våtmarker, eftersom de fungerar både som flödesutjämnare och som sedimentationsmagasin.I Steningedalen, Märsta, finns en dagvattenanläggning med dammar och översilningsytor, vars syfte är att rena dagvatten från ett avrinningsområde på ca 7200 ha. Vattnet leds till dammarna via en dagvattentunnel vars primära syfte var att leda vattnet förbi Märsta centrum. Tunneln är ca 3100 m lång, sprängd och delvis i betong, och har ett skibord installerat i tunnelmynningen med syfte att skapa ett sedimentationsmagasin samt att vid höga flöden leda vattnet förbi dammarna direkt till Märstaån. I denna studie har reningseffekten av denna dagvattentunnel utretts.

Män som har sex med män ? utmaningar och strategier i svenskt utvecklingsarbete

Introduction: Men who have sex with men (MSM) is a vulnerable group with regard to HIVbecause of biological factors, lifestyle, discrimination and, in some parts of the world,criminalization. From a public health perspective it is important to include MSM in order to securea high-quality HIV prevention but also to safeguard human rights (HR) for this group. However, itis only recently that the Swedish development cooperation agencies have begun to integrate MSMin HIV prevention. Objective: To examine how employees of Swedish institutions responsible fordevelopment cooperation manage the vulnerable group MSM when providing support for HIVprevention programs and human rights programs. Topics relate to challenges and strategies tointegrate MSM in HIV prevention, which achievements have been obtained, and how to practicallydeal with the criminalization of the group.

GIS och statistik vid dräneringsområdesvis kväveläckagebeskrivning i Halland

The last decades have shown increased nitrogen leeching from soil to water recipients. This is inSweden mainly due to over-manuring of agriculture land, effectivization of drainage systems and thedeclining extent of wetlands. The accumulated amount of nitrogen in water doesn?t only make itunsuitable for use by humans and cattle, but also decreases the biological diversity as well as negativelyaffect tourism and fish industry. In the most severe cases shallow maritime grounds can be completelydepleted of oxygen due to decomposition of the increased amount algae and plankton growth.This study have the aim to describe and quantify the nitrogen leeching from the Genevad drainagebasin, located in southern Halland, Sweden.

Erfarenheter av utedrift med köttdjur i Sverige och Kanada :

Beef cattle wintering outdoors should be provided a shelter, e.g. a type of barn or corresponding. This type of production requires appropriate soil types and secured animal welfare. For example, a clean and dry resting place needs to be provided to the animals. To receive an exemption for buildings the farmer has to have something equivalent that provides an adequate shelter.

Modellering av kväveavskiljningen under fyra år i en anlagd våtmark på Lilla Böslid, Halland

Populärvetenskaplig sammanfattning: Kvävebelastningen på sjöar och hav har ökat markant de senaste tiotal åren. Jordbruket stårför ca 50 % av de svenska kväveutsläppen som människan bidrar till. En ökadkvävebelastning på haven kan leda till övergödning, vilket får en stor negativ effekt påvattenekosystemen. Ett sätt att minska övergödningsproblematiken är att öka vattnetsuppehållstid i landskapet genom att anlägga nya eller restaurera gamla våtmarker ijordbruksintensiva områden som t ex. Halland och Skåne.

Förbehandlingstekniker och LCA för rötning av organiskt avfall : Modellkonstruktion och Utvärdering med ORWARE

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.
