Soil carbon in small-holder plantain farms, Uganda : a comparison between agroforestry and non-agroforestry

Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC) compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on crops during drought. The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.

Ants and termites in small-scale plantain farms in Uganda : a comparison between agroforestry and non-agroforestry farms

This study was conducted in Kkingo district, west of Masaka, Uganda. It compared soil macrofauna abundance in non-agroforestry farms with that of agroforestry farms. The agroforestry farms had participated in the Vi Agroforestry´s program between 1995 and 2006, and continued on their own after 2006, when Vi Agroforestry left the area. The soil macrofauna is important for soil structure and processes that are contributing to soil organ-ic matter decomposition and nutrient mineralization. They are also predators of potential pests.

Cooking banana farming system in rural Uganda : a comparison between agroforestry systems and non agroforestry systems

The demand for food, feed, fibre and fuel has increased in Uganda over the past 50 years due to population growth. Recurring extreme climate events such as drought and flooding, in combination with large-scale land degradation, have led to declining crop yields. Lack of equipment, money and socio-economic issues has contributed to low yields. However, the soils in Uganda have the potential to produce much higher yields than they do today. This study, which was carried out in April-June 2013 in Kkingo District, south-east Uganda, examined the effects of agroforestry on yield of cooking bananas in small-holder farming systems. Six farms practising agroforestry and six farms with no agroforestry, which were chosen in cooperation with the NGO Vi Agroforestry, were compared.

Ruminants´production within agroforestry systems in rural Rwanda : production benefits and problems

Intercropping involving trees is called agroforestry and makes it possible to get higher production for every area unit. The trees can function as food, fodder, fuel, medicine; prevent mark erosion and much more. Agroforestry can also be combined with animal husbandry. The aim of this study was to document the animal production systems used by rural small-scale farmers maintaining ruminants and using agroforestry in the northern province of Rwanda. The farmers using agroforestry is expected to have higher milk yield than average due to homegrown protein. The method used during the study was semi-structural interviews with booth open and closed questions. In order to get in contact with farmers that matched the criteria; small-scaled rural farmers with ruminants and using agroforestry, the ?Vi Agroforestry Programme? (Vi-Life) in Kigali were contacted and the staff worked as supervisors, translators and contact with the farmers throughout the study. During the study nine individual farmers, two cooperatives breeding sheep and one group interview were conducted.

Whispers in the forest : a field study about communication within Vi-agroforestry

The purpose of this study is to explore and understand the social and structural dynamics of an organization working with questions regarding development. The organization in question is Vi-agroforestry, a Swedish based NGO that works around the lake Victoria basin and the focus will be on their office in Rwanda. I have used a qualitative approach and conducted participatory observation as well as semi-structured interviews to gather data. I have emanated from the individuals in the organization by using a theory of microsociological organisationperspecive to understand how the employees create and is created by the existing social structures. (Blomberg, 2003) Even though the office in Rwanda only is a relatively small part of Vi-agroforestry?s operations it is still highly individual and independent from the rest of the organization.

Fodder to ruminants within agroforestry systems in Rwanda - species and management

Rwanda is one of the poorest countries in the world and about 70-80 % of the population lives in rural areas. The land is strongly affected by land erosion which makes it difficult for the agriculture and food production. Agroforestry is a system where tree plantation is combined with livestock- and crop production. The system provides soil fertilization and binds the soil together. Some of the trees used in agroforestry systems are also used as fodder.

Hållbar utveckling i Viktoriasjö-regionen, del II : en fallstudie av bönders empowerment kopplat till participarory rural appraisal i Viskogen Masaka/Rakai, Uganda

This Master?s thesis is one of two parts of a combined project called Sustainable development around the Lake Victoria, the purpose of which is to investigate the importance of local anchoring and active participation in the work towards sustainable development. The present study aims to investigate whether men and women are empowered by the participatory rural appraisal (PRA) process promoted in their villages by the VI Agroforestry Project Masaka/Rakai. The study is primarily based on interviews with farmers within the project area and brings up a local perspective on the concepts sustainable development, active participation and empowerment. The study shows that to improve the farmers? livelihood and to create a sustainable development in the community, the farmers have to be actively involved in, and in control of, the process.

Ekosystemtjänster av alley cropping i tempererade klimat : litteraturstudie

Den så kallade ?gröna revolutionen? inom jordbruket inleddes på 1960-talet och innebar högavkastande grödor, ett oreflekterat högt användande av kemiska bekämpningsmedel, samt intensiv bevattning och mekanisering. En underdrift är att påstå att detta skapat minst sagt stora problem för jordens ekosystem. Ett alternativ för hållbar matproduktion är agroforestry, som innebär produktion av träd på samma mark som produktion av jordbruksgrödor. Systemet är bland annat utvecklat för att förbättra ekologiska samspel.

A value chain analysis for timber in four East African countries : an exploratory case study

This study is a value chain analysis for timber in East Africa. It was commissioned by Vi Agroforestry, a nongovernmental organisation registered in Kenya, Rwanda, Uganda and Tanzania engaged in a rural development program that involves promoting tree planting and enterprise development (Vi Agroforestry, 2012). The purpose of the study was to identify and describe common value chains for timber in the countries where Vi Agroforestry operated. Value chain is a concept and a framework describing how to structure information regarding activities included in satisfying a certain customer need, e.g. procurement, logistics, transactions, production and marketing.

Leaf area index in Vittelaria Paradoxa parklands in Burkina Faso estimated by light interception and leaf sampling

Burkina Faso as well as most sub-Saharan African countries struggle with providing food for a fast growing population. The dominating farming system is agroforestry parklands. Agroforestry parklands can broadly be defined as areas where scattered trees occur on farmlands as a result of selective clearing. The presence of trees in crop fields may in the long term have a positive effect on the production of annual crops. It is commonly discussed, but not proven, that the presence of trees leads to increased groundwater recharge due to higher infiltration capacity of the soil.

Med vatten som begränsande faktor : en litteraturstudie om artval och skötsel av agroforestrysystem i Östafrika

Träd har alltid använts inom jordbruket och de senaste åren har de spelat en viktig roll i miljö- och klimatforskningen. Att integrera träd i jordbruket kan ha en mängd fördelar, såsom förbättrad jordstruktur och ökad avkastning. Östafrika är en av regionerna där man använder och forskar inom agroforestry. Delar av regionen har problem med svår torka, varför vattentillgången är en begränsande faktor inom jordbruket. Risken finns att trädens konkurrens med grödorna inte väger upp de fördelar som ett agroforestrysystem kan medföra.
