Monitoring lion movements
Prevention of lion predation towards African livestock is of great importance due to the economical losses farmers have because of this. Predation is also one of the main reasons for human-wildlife conflicts and lions often get killed because of it. Therefore, a pilot study using camera traps was conducted to monitor movements of lions and other wildlife through a wildlife corridor in Ol Pejeta Conservancy. The results were compared with a previous study that counted prints in the soil in front of the corridor. Due to theft risk the cameras had to be taken down and pictures were only collected from nine days.
Frost hardiness of grapevine cultivars as affected by ground cover under Scandinavian conditions
Cultivation of grapevine is novel under Scandinavian conditions. We studied the impact of ground cover on frost hardiness of grapevine cultivars in Northwestern Scania in a two-factorial trial with four cultivars Solaris, Pinot Gris, Siegerrebe, Ortega and three kinds of ground cover (open soil, plastic cover and gravel). The study was conducted in a grapevine orchard, planted in May 2009, in Broddarp on Bjärepenisula Sweden (N latitude 56°; longitude E 12°). Soil and air temperature were monitored continuously.
Frost hardiness measurements were performed every second week from late September to early December 2009. Frost resistance, LT50, was determined by electrolyte leakage measurement of the upper stems after artificial freezing at -15 °C.
Medborgardriven stadsdelsutveckling- Lower Ninth Ward, New Orleans
Through this thesis, we want to discuss how the marginalization of people, several precedent political, city planning- and engineering decisions resulted in a catastrophic outcome after hurricane Katrina in New Orleans 2005. We also put forward a case study of the Make It Right Foundation, to demonstrate how the residents of the Lower Ninth Ward are involved in the urban development of their community. We would like to draw attention to the power of citizens and how they can influence the urban development of a community after a trauma. This study also focuses on the mission of The Make It Right Foundation: which is to rebuild the Lower Ninth Ward with firm concepts on sustainable development where all dimensions are accounted: ecological, social, cultural and economic.
The empirical data was collected by a field study in New Orleans 2010-03-22 and semistructured interviews were made during the same days..
Turbiditet som ersättningsmått för totalfosforhalt i kustmynnande vattendrag i Östergötland
Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.
Re-design of Toledo Riverfront : from industrial past to sustainable biodiverse future
Effects of climate change, urbanization and global homogenization are resulted in the degradation of land and losses of natural habitats. Ecological design integrates nature into urban environment by respecting natural ecological principles and processes and creating resilient
urban biotopes which also can be used by local urban communities.
The aim of the thesis is to answer the research questions: How ecological design principles can be applied for re-design of Toledo Riverfront (with requirements of the design competition)? and What is the ecological design in landscape architecture? I participated in the USA design
competition with the aim to create a vision and redesign of Toledo Riverfront in Ohio State, USA. The site is located in the south point of Lake Erie. As a result of a long industrial activity, riverfront of Toledo had been transformed into inaccessible and abandoned brownfields.
In my proposal I applied ecological design principles on three scales:
the city of Toledo by reinforcing of ecological connection and creating green corridors along the river; the intermediate scale by suggesting public parks along the river front and on the fine level by proposing detailed design including remediation of the site and use of dredged
material.
Planering i staden. Hyllie stadsdel- från stagnation till integration?
This thesis deals with urban planning in connection with social and spatial integration.It´s a study of a new planning project in Malmö in southern Sweden. It´s an interesting case because this new, fashionable area will be located next to areas facing socio-economical challanges and stagnation. By using two theoretical models I analyse how the visions for planning a city are formulated and applied when policy is going to be operated. My models are ?the balanced community? and ?the dual community? .The conclusion is that the focus for Malmö and Hyllie is going towards emphasing the creation of attractive but segregated districs in a city.
Djurhushållningen i Västergarn : en osteoarkeologisk fallstudie av animalt benmaterial från Snauvalds 1:2, Västergarn, Gotland
In this Bachelor thesis an animal bone material from Västergarn parish is analyzed and discussed. The purpose of this thesis is to gain more knowledge about the Viking Age/Early Medieval Västergarn. Västergarn has a few remains from former days which have been discussed throughout the years and are still a bit of a mystery for archaeologists. The main focus is to inquire into whether Västergarn was an urban, complex society or a rural settlement. This will be done by studying the animal husbandry from the property of Snauvalds 1:2.
Integrated Green Spaces in Urban Areas : a case study of inner Brisbane
The review of Integrated green spaces in urban areas ? A case study of
inner Brisbane highlight the significance of addressing characteristics,
qualities and landscape values in our outdoor environment. The importance
of green spaces to the wellbeing of people in the city and the ecological,
social and cultural values they carry are widely recognised in the
field of urban and regional planning. At the same time population growth,
climate change and urban development put planners and scientists in a
challenging position where new solutions must be put on the agenda in
order to accomplish sustainability. Open space strategies, collaboration
between stakeholders, public participation, learn from earlier failings and
a ?value-led? approach facilitate the managing of open space.
Brisbane is located in the fastest growing metropolitan region in Australia.
The city´s open space landscapes offer cultural, geographical, recreational,
social and scenic amenity assets, which make a major contribution
to the regions identity they a wide world known for.
Kvalitet i brödvete :
The quality of bread wheat is a large subject to study. The quality rests on two legs. The first one is the inheritance of specific characters, which can be influenced through plant breeding and type of cultivar. The other one is the environmental influences, such as crop rotation, nutrition, harvest and storage. The latter factors are possibly to affect through cultivation practices, while other factors are not possible to influence on for the grower, such as seasonal changes of weather and the soil content.

The use of artificial insemination in dairy farms in urban/peri-urban Kampala, Uganda : a study of knowledge, attitude and practices
Uganda is one country with fastest growing populations in the world and with more than 25% of the population living in poverty. There is a rapid rural urban migration with increasing demands for food for low income earners especially in these areas. One way to mitigate food insecurity is to increase milk and meat production efficiency, and thus reproductive performance of cows is crucial for good production. A well-documented strategy for improving dairy cow productivity through faster genetic improvement is to breed dairy cows using proven semen via artificial insemination (AI). AI has been used in Uganda for over 60 years but only less than 10 %, a small population of the country?s herd has been bred that way.
The aims were to study knowledge, attitude and practices factors influencing cow fertility results on dairy farms around Kampala using AI and to propose ways of promoting increased use of AI in Uganda.
Utbildning av urbana matproducenter - Framtidens nya matproduktionsnäring?
Denna studie har genomförts som en del i Mistra Urban Futures projekt Grön Produktion. Projektet vill utveckla stadsodlingsprojekt och affärsidéer och har beslutat att göra detta genom att titta på områdena utbildning och affärsmodeller. Denna studie riktar sig mot området utbildning och har undersökt hur utbildning skulle kunna öka urban matproduktion för att bidra till skapandet av en ny matproduktionsnäring och samtidigt öka städers ekologiska hållbarhet. Frågeställningar som behandlades var hur en utbildning av urbana matproducenter skulle kunna stärka och lyfta befintlig matproduktion i städer till en ny matnäring, vilka kunskaper som urbana jordbrukare har och önskar samt vilka kunskaper som marknaden önskar. För att besvara detta genomfördes kvalitativa intervjuer av olika aktörer inom den potentiella matproduktionsnäringen; kommunen, odlare, handeln och restaurangbranschen.
Elever och lärares syn på engelskundervisning : En kvalitativ intervjustudie om motivation och integrering av engelska
Visby is a city that at first glance is of medieval origins. The popular image of scientists today is that the city was formed in the Middle Ages. According to some of the researchers Visby was formed during the Viking Age, it is based on the basis that the area has been used for a long period. Urban development in the Nordic countries is complex and there are different opinions as to why the Nordic cities emerge. It is important to shed light on the underlying process on why cities are emerging to provide clarity as to why Visby city is emerging.
Fältskiktsarter i naturlika planteringar : vilka råd kan ekologer ge?
This paper appeals to professionals working with green questions. It intends to create a discussion about which plant species that can be established in a fieldlayer of a naturelike planting on fertile agricultural land. To initiate the essay, a studie of which values that can be connected with an establishment of a fieldlayer was performed . A part of Tor Nitzelius Park in Alnarp, a so called naturlike planting on fertile agricultural land, was used as a model for the choice of species. With the aid of soil values, photos and a list of current species, interviews with four ecologists were performed.
Undervegetation : användning av vedartade marktäckare i anläggning
The use of the robust and durable woody ground covers is increasing, not in the least in public places. The group includes low shrubs of different height that effectively build low, tight vegetation that covers the ground. Despite all the good qualities the knowledge about them is quite low and there are ideas about them of being dull.
The woody ground covers manage to struggle against weeds effectively by competing for nourishment and water, but above all, by the canopy of the ground covers that prevent the weeds from getting enough light. In that way the woody groundcovers can effectively compete with the annual weeds.
