26. Insect diversity on clearcuts in boreal forest landscapes
Sammanfattning : Intensive management and loss of natural disturbance dynamics in boreal forests leads to habitat loss and degradation for forest dwelling species. As a consequence, many species have become threatened, especially those dependent on dead wood. LÄS MER
27. Non-industrial private land use and forest management : landscape and policy perspectives
Sammanfattning : Demand for raw materials and food has long been rewarding intensive production oriented land uses, which has led to various environmental and social issues. Policies attempting to reconcile the interests and claims of different groups in society emerge from political process. LÄS MER
28. Understanding crop and farm management : links to farm characteristics, productivity, biodiversity, marketing channels and perceptions of climate change
Sammanfattning : Agriculture faces challenges in meeting rising demand for food, feed, fibre and fuel while coping with pressure from globalisation, limited natural resources and climate change. Farmers will choose management practices based on their goals and available resources and these practices will influence farm performance. LÄS MER
29. From Betterment to Bt maize : agricultural development and the introduction of genetically modified maize to South African smallholders
Sammanfattning : Agriculture has received renewed attention in poverty reduction efforts in Africa in recent years, and there are hopes that GM crops could have an important role in helping increase smallholder yields and reduce poverty. Drawing on critical discourse analysis (CDA) and livelihoods perspectives, this thesis examines the ideas governing the Massive Food Production Programme (MFPP), an agricultural development programme aiming to reduce poverty by raising agricultural production in Eastern Cape Province, South Africa, and its local effects when implemented in smallholder communities.

30. Tree stem diameter estimation from terrestrial point clouds
Sammanfattning : Forest owners, governments, and environmental organizations demand forest information for planning of forest operations, estimation of value, and for environmental monitoring. This information is collected using airborne and satellite remote sensing combined with field inventory of sample plots. LÄS MER
