During the 1960´s and 1970´s the number of grey seals in the Baltic Sea was decreasing rapidly, mostly due to hunting and toxic substances like DDT and PCB. When hunting became less intense and toxic substances decreased in the environment the grey seal population started to increase. Today grey seals are found common in the Baltic Sea and have started to become a big treat and a problem to the fishing industry. The grey seal destroys and enters fishing traps and consumes large quantities of the fish that have been caught.The knowledge of the grey seal, like abundance and food preferences, is today limited. It is also important to define the position of the grey seal in the ecosystem in the Baltic Sea and to be able to predict changes that could occur if the population would rapidly decrease or increase.

Horseracing is frequently referred to as the engine behind all horse activity in Sweden and it can be divided in to two main branches: harness racing and thoroughbred racing (HNS, 2008). Jump racing is a part of the thoroughbred racing and the jump racing is characterised by jumps on the racing track. Jump racing has been a part of the Swedish horseracing for over hundred years, but it has in recent years suffered from low economic profitability and been threatened by discontinuance (ATG & SG, 2008). Svensk Galopp, who is governing the horseracing in Sweden, has decided to increase the importance of jump racing. A workgroup was created for this purpose, and as a result of their work a strategy for the jump racing is supposed to be delivered in April 2009 (pers.

Över hela världen pågår en kraftig urbanisering och idag lever mer än hälften av alla människor i städer. Många utvecklingsländer hinner inte med att generera hållbara och alternativa försörjningsmetoder till den allt större urbana befolkningen. Allt fler lever i en tillvaro som präglas av fattigdom. Kraftfulla planeringsstrategier krävs för att förbättra dessa människors levnadsförhållanden och därmed också verka för en hållbar utveckling. Uppsatsen presenterar det urbana jordbruket som en i dessa avseenden möjlig strategi. Urbant jordbruk finns i alla städer och har gjort det i alla tider.

Landscape urbanism has for the last decade been a topic for debate among practitioners and theorists involved in forming the contemporary city. The advocates for landscape urbanism mean that traditional dichotomies like city and country are invalid to illustrate the contemporary urban realm. Rather, a new urban morphology has evolved, which calls for new methods and models when approaching the city. Landscape urbanism suggests a revaluation of landscape in order to develop these approaches. This paper sets out to map how this is addressed within landscape urbanism.

Sweden has almost 600 000 hectares planted with lodgepole pine, and large areas are soon ready to be clear-felled. The provenances that have been planted are producing high level of permanently closed, so called serotinous, cones. In their natural setting, the Canadian boreal forest, these cones are opened mainly after crown fires when the heat make the resin between the cone Scales melt, which releases the seeds. This is viewed as an adaption to the fire regimes that prevail over the natural distribution area of lodgepole pine. Because of the short flame-exposure that occurs in a crown fire, the seeds can survive.
