Supply & value chain analysis of onions in Ethiopia
Ethiopia is a developing country situated on Africa?s horn. Ethiopia ranks 173rd on United Nations human development index where the least developed country ranks 186. About 85%
of all Ethiopians are employed in agriculture. Onion is one of the basic ingredients in the Ethiopian cuisine and thus an important crop.
Ingen skola är en ö : en studie av förutsättningarna för projekt med närproducerad skolmat på Sollerö skola
Sedan nästan tjugo år arbetar pedagoger och kökspersonal på Sollerö skola med projekt som syftar till att öka miljömedvetenhet hos eleverna och servera dem närproducerad och näringsrik skolmat. Detta arbete består bland annat av odlingar där skolpersonal, elever och föräldrar tillsammans odlar potatis, lök, morötter och rotsaker till skolmåltiderna. Många av de engagerade i verksamheten uttrycker dock att de upplever motstånd från skolledning och kommuntjänstemän, vilket leder till frustration och osäkerhet kring verksamhetens framtida överlevnad. I denna uppsats undersöker jag hur de engagerade i verksamheten påverkas av Mora kommuns policy för verksamheten, hur viktigt skolledningens stöd är för verksamhetens fortlevnad, samt vilka strategier de engagerade använder sig av för att påverka sina förutsättningar. För att försöka förstå detta har jag vid två tillfällen besökt Sollerön och de platser som är aktuella för verksamheten, intervjuat sju personer som är eller har varit aktiva i Sollerö skolodlingar samt deltagit i ett verksam-hetsmöte.
Profitability and competitiveness of grain handling at farm level
The Swedish agricultural sector is currently experiencing substantial structural changes, where the number of agricultural enterprises continuously decreases and the average farm size increases. In order to maintain competitiveness, it is important to be aware and adapt to changes concerning the surroundings of the company (Johnson et al., 2011). Agricultural commodity prices sharply fluctuate on the global market in recent years, affecting the profitability of farmers. High volatility market requires tools to reduce price variations and increases the need of decision-making (Bouder & Beth, 2003). Farm-based grain handling facilities increases the sale options regarding agricultural commodities; a flexible strategy to get additional compensation for the storing the grain produced on the farm (Edling, 2002; Edwards, 2013).
Utveckling av substratmixen vid Mosseruds biogasanläggning : Substratkartläggning och rötningsförsök i laboratorieskala
The world?s growing need for energy together with a desire to ward off the worst consequences of global climate change has resulted in a never seen desire to invest resources in renewable energy sources. Biogas production through anaerobic digestion is one of those growing energy sources. In Sweden there are over two hundred plants that uses this biological process to break down organic substances while producing carbon dioxide and the energy-rich gas methane.This master?s thesis has focused on development of the mixture of different organic substances that is treated at a specific plant, namely Mosserud biogas plant.
Concentration and offtake of trace elements and macronutrients in Italian ryegrass (Lolium multiflorum Lam.) and spring barley (Hordeum vulgare L.) grown on soils amended with water treatment residual sludge
Aluminium sulphate (Al2(SO4)3) is usually added during the drinking water treatment processin order to precipitate organic and inorganic material, resulting in aluminium-based drinkingwater treatment residual sludge (WTR). Since 2003 Swedish law no longer permits WTR tobe deposited in lakes, and there is an interest to explore the possibility to utilize WTR as soilamendment. The aim of this study was to examine the effects of WTR application on cropgrowth and concentrations of macronutrients and trace elements (including micronutrients andpotential toxic elements). A greenhouse pot experiment was conducted with three soils; a clayloam rich in phosphorous (P), a loamy sand rich in P, and a silty loam with a low soil Pconcentration, and two crop species Italian ryegrass (Lolium multiflorum Lam. cv.
Metodik för resistenstest i renkavle : en studie om herbicidresistens; mekanismer, detektion och åtgärder
Herbicide resistance is the result of an evolutionary process where a population gradually changes from being susceptible to being resistant to an herbicide. The resistance mechanism is usually a change in the biochemistry of the weed, but in some cases changes in morphology or growth rhythm. The change is caused by random mutations. Two resistance mechanisms are found in black-grass; target site resistance and metabolic resistance.Black-grass is a tufty, winter annual grass weed, which is mainly found in milder climates. Black-grass is a big problem in Southern Europe.
Kålgallmygga, Contarinia nasturtii Kieffer : en växtskadegörare på kål
The purpose of this paper is to examine what problems cabbage growers have with the
Swede Midge. The last few years the Swede Midge, Contarinia nasturtii, has become
a larger problem for cabbage growers in several countries in Europe as well as in
Sweden. In Canada the problems are so severe that the midge is classified as a
quarantine pest and therefore certain rules have to be followed. I have collected facts
of the biology, host plants and reproduction of the Swede Midge, as well as the
growers experiences and the occurrence of the midge in Canada, Europe and Sweden.
The Swede Midge is hard to control because of its short life cycle and the larvae are
protected between the heartleaves of the plant. When the larva feeds on the growth
point the plant becomes distorted, in some cases several heads develop or none at all.
When the midge infests spring rape its flower buds become undeveloped and rosette
like.
Vallbrott med hjälp av grisar :
To investigate the possibilities for effective soil tillage, that could imply lower costs,
lower negative environmental impact and in addition a meaningful occupation for foraging pigs, a field experiment was carried out in Gränna, Småland, during growing season 2006.
The experiment contained two treatments that were repeated three times and were carried
out on a couch grass-infected fallow on a light soil close to Sweden?s second largest lake, Vättern. Ploughing was one treatment and pig rooting followed by ploughing, was the
other. The experiment was conducted according to the guidelines of organic growing and
seedbed preparation was done the same way in the two treatments. The pigs, three groups
of five half-year old Linderödssvin (an old Swedish breed), was encouraged to perform
an even tillage by strip-grazing, i.e.
Aktiviteten hos thymidinkinas 1 i serum från hundar med juvertumörer och malignt lymfom
With the farming methods of the past century the agricultural landscape has changed. This has led to the fact that many habitats and species have been significantly reduced. Sweden is committed to the preservation of biodiversity through various conventions and laws. In the EU's Common Agricultural Policy there are currently agro-environmental schemes, which were created as an instrument for reducing the negative impacts of agriculture on nature and environment. Within this system any farmer who perform environmental measures are financially compensated for this.
Försök med olika såmaskiner vid konventionell sådd och direktsådd
In this thesis, two studies with different drills were included. In one of the studies two drills were compared: Väderstad Rapid and Väderstad Spirit. In the other study various drills for direct drilling were compared.
The study with Rapid and Spirit was placed in two locations with different autumn tillage; one on ploughed land in Uppsala and one on cultivated land in Västerås, both with relatively high clay content. Rapid drills have a single disc coulter, while the Spirit drills have a double disc coulter. Various aspects were compared such as aggregate distribution, seed placement, emergence, crop yield and economic outcome.

Bosättning, agrarkris och fäbodväsende : vegetations- och markanvändningshistoria i Läde, Dalarna
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.
Driving forces of land use : underlying factors in peri-urban land use
Swedish agriculture faces future challenges regarding food production and land use. Increased competition for agricultural land creates complex situations, where conflicts may arise when productive crop land is in demand not only for food production but also energy- and fodder production. On top of that there is an obvious conflict of goals between agricultural production and non-agricultural exploitation of agricultural land. In several emerging economic regions it is noticeable how agricultural land is being expropriated for development of urban settlement and infrastructure, carrying potentially significant long-term effects.
During the last decade the exploitation of agricultural land in activities other than food production has increased in Sweden and is expected to continue in the same manor. Approximately 700 hectare of land in Sweden is diverted from food production, annually, and in 2013, the Uppsala Municipality showed the greatest change in land use of all municipalities (SCB, 2013).
Effects of biogas residues on respiration and denitrification in arable soil : evaluation of methods, microbial activity and agronomic implications
Agricultural soils constitute the base in human food production and soil content of organic matter and plant nutrients together with soil microbial activity are all important parameters for high crop yield of good quality. These parameters are dependant on proper fertilization.Anaerobic digestion of organic wastes for biogas production generates a liquid residue called biogas residue (BR). It contains organic material and plant nutrients which makes ita potential fertilizer for arable cropping. However, it also contains heavy metals and toxic organic compounds and it is therefore in need of evaluation before usage.Microbial tests were performed aiming to evaluate the agronomic traits of four different BR and to find a viable procedure for evaluating slurry fertilizers. Two experiments where soil respiration and soil potential denitrification activity (PDA) was measured at fertilizer addition were performed.
Livet mellan husen : ett utvecklingsförslag för Disagården
The open air museum of Disagården is situated in the Old Uppsala parish,
Uppsala municipality, are projected to portray a double row village, before
the land enclosure, on the Uppsala plain during the 1860s and 1870s.
Disagården operates under the County Museum of Uppland and serves as an
exhibit of Uppland's farming culture during the late 19th century. However, an
open-air museum is a complex institution where many interests are linked
together. Disagården aims to simultaneously portray an historical
environment while offering broad public appeal.
The Disagården open air museum was inaugurated in 1931 and consists of
relocated buildings that together form three farm complexes "Gränbygården",
"Skuttungegården" and "Bärbygården".
The thesis explores how the close surroundings of a typical farm in
Uppland looked during the 1860s and 1870s. This historical depiction has then
been applied to Disagården in a development suggestion creating a
foundation from which Disagården can structure the close cultivation of the
different farms. The basis of the development program has primarily been
compiled through archival and literary studies but also through on-site visits
and interviews.
How did the concept of open air museums start and what were the ideas
behind the concept? Which external influences affected the situating of
cultivations and buildings? Which crops and species were present on the
farms in Uppland during the specified time period? What was the relation of
the different structures to each other? Which organizations had influences on
the farmer's household of the Uppland plain? The thesis attempts to clarify
the answers to these questions.
The influences affecting on the farmer's household in Uppland were
probably numerous.
