Landlocked Tajikistan is situated in Central Asia and is not only the smallest republic of Central Asia, but it is also one of the most mountainous with some of Central Asia?s highest peaks. Tajikistan is currently and historically the most financially disadvantaged country within Soviet Union/Russian territories. Agriculture is the main occupation for more than half of the country?s population. Unfortunately, however, only 7% of Tajikistan is arable land and the agriculture productivity is low.

Studien genomfördes i Shompole i södra Kenya. I det här området är invånarna herdar som förlitar sig på kor, får och getter som sin enda inkomstkälla. De föder upp boskap under extensiva förhållanden, med naturligt bete som huvudsaklig födokälla för sina djur. Sex besättningar av den typen ingick i studien som genomfördes från mitten av december 2009 till mitten av februari 2010, vilket gav totalt 65 observations-dagar. Syftet med studien var att samla in födo- och förflyttningsbeteende hos nötkreatur, får och getter på bete.

Sammanfattning Idag genomförs många smärtsamma ingrepp på getter, så som kastrering och avhorning. Trots att det i svensk lagstiftning står att djur inte får utsättas för onödigt lidande finns det idag få smärtlindrande läkemedel som är godkända till get. Tidigare studier har visat att opioiden buprenorfin är olämpligt till getter. Syftet med den här studien var att genom att mäta olika fysiologiska parametrar undersöka om opioiden butorfanol kan vara eller inte vara ett lämpligt medel för getter. Läkemedlet är idag godkänt som smärtlindring till häst, hund och katt.

By using pollen analysis, 14C-dating and historical sources, I studied the history of vegetation and land use at an abandoned forest settlement near the Lade summer farms in the parish of Mora, Dalama. The aim of this paper is to investigate the agricultural establishment and development, the effects of this on forest vegetation, and the origin and development of summer farming. The analysis of pollen in a peat core revealed that a settlement was established at Lade around 1000 AD. Cereal cultivation, hay-making on the mire and extensive forest grazing were intro-duced as a complete agricultural system. Pollen analysis and the presence of ancient fields suggests that cultivation took place on permanent fields. Barley was the main crop, but rye and hops/hemp were also grown at the settlement.

The forest and mire landscape surrounding the north Swedish villages have been of fundamental importance through time for the farmers. In the Scandinavian summer farm system the forest and mire pasture was used to its full potential. The system consisted of smaller summer farms some kilometres from the main farm in the village, and were the livestock grazed in the forest around the summer farm. The livestock affect their environment, and grazed forests generally contain a higher biodiversity than an ungrazed forest. The overall aim of this thesis is to understand the impact of livestock grazing on a northern forest ecosystem over a long time period.

Biodiversity is under threat in Sweden and many species are on the brink of extinction. This is mainly due to the large-scale drainage projects during the 19th and 20th century and the increasingly intensive land use in agriculture and forestry. The intensive land use with sharply defined boundaries between the production units has in many cases led to either overgrazing or overgrowing. As a result many species have been pushed back to "leftover" habitats like shooting ranges, power line corridors, roadsides, dumps, embankments and other similar areas. Therefore the question has been raised, wether or not it is needed to re-introduce large herbivores into the wild in order to maintain the biodiversity that is related to the extensive land use.This study has been conducted as a literature review and will focus on the European bison?s (Bison bonasus) impact on other species and biodiversity; conditions for reintroducing large herbivores in Sweden are also discussed.Free roaming populations of large herbivores have a positive impact on plants, insects and many other groups of organisms.
