  1. 31. A comparison of protein complexation capacity among six boreal species and the consequences for nitrogen mineralization

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Jennie Sverker; [2009]
    Keywords : protein complexation capacity; nitrogen cycle; fire chronosequence; succession; boreal species; boreal ecology; nitrogen mineralization; competition;

    Abstract : Nitrogen (N) is considered to be the most limiting nutrient for productivity in boreal forests, and the ability of plants to complex protein during decomposition is considered to be an important mechanism by which some plants regulate the N cycle. In this study I investigated whether six boreal plant species differed in their ability to complex proteins. READ MORE

  2. 32. Relating soil properties to biomass consumption and land management in semiarid Sudan : a minor field study in North Kordofan

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Helen Thorstensson; [2009]
    Keywords : biomass; agroforestry; Sudan; semiarid; physical geography; acacia senegal; geography; gum arabic; nutrients; Earth and Environmental Sciences;

    Abstract : I Sudan och många andra delar av Afrika är biomassa den huvudsakliga energikällan. Ved används för att göra upp eld till matlagning och uppvärmning av hus och mycket biomassa går också åt till att bygga hus, staket, verktyg och annat. READ MORE

  3. 33. Participatory watershed management to decrease land degradation and sediment transport in Kagera and Nyando catchments of Lake Victoria basin

    University essay from Tema vatten i natur och samhälle

    Author : James Gunya Kenge; [2009]
    Keywords : Kagera and Nyando catchments; Lake Victoria basin; land degradation; participatory watershed management; policy;

    Abstract : Attention to participatory watershed management is increasing across the developing world as soil erosion continues to degrade agricultural land; reservoirs and irrigation infrastructure are clogged with sediment. The realization of the importance of watersheds is crucial for sustainable utilization especially in developing countries where rural livelihoods and economies are highly dependant on the exploitation of natural resources.

  4. 34. The effect of push-pull management and different fertilization strategies on maize crop yield in central Kenya

    University essay from SLU/Swedish Biodiversity Centre

    Author : Peterson Newton Muchiri Njeru; [2009]
    Keywords : Soil fertility; central Kenya highlands; manure; fodders; fertilizer; smallholder farmers; ‘push-pull’; monoculture; Kenya;

    Abstract : The high population pressure in central Kenya has lead to continuous cultivation with minimal application of nutrient, resulting in nutrient depletion. A study was conducted to determine the effect of 'Push-pull' (intercropping maize with desmodium and napier grass) strategy management and nitrogen application on maize grain yield and soil fertility on smallholder farmer’s fields in three districts of central Kenya highlands.

  5. 35. IWESS, an integrated water, energy and sanitation solution : A holistic approach to reach sustainability trough organic waste management for the Lake Victoria Basin, Kenya

    University essay from Institutionen för teknik och samhälle

    Author : Erik Martinsson; Emil Martinsson; Sören Säf; [2008]
    Keywords : ecological waste water treatment; slow sand filtration; deforestation; eutrophication; global warming; appropriate technologies; anaerobic process; biogas; source separation; nutrient re-circulation; waste water reuse; waste to resource; soil erosion; soil fertility; desertification;

    Abstract : The process of allocating necessary resources like clean water, fuel/energy and food have resulted in an unsustainable use of natural resources causing problems with Soil erosion, soil fertility, desertification, deforestation, eutrophication and global warming. The purpose of this study was to gain information on the functional design of a waste management system enabling the organic components of domestic waste to be processed as useful resources while at the same time allow them to be re-circulated.
