Vilka förhållanden är gynnsamma för mjölkkors naturliga beteenden - förekommer skillnader i djurhållningen vid konventionella respektive KRAV certifierade lantbruk? / Which situations are favorable for natural behaviours of dairy cattle - are there differences in the cattle management at conventional and KRAV certificated farms?

Karlsson, Jenny January 2010 (has links)
<p>The aim of this study was to investigate which elements that functioned in a positive way on the natural behaviors of dairy cattle among KRAV certificated and conventional farms. The study was based on reading of earlier research and completed by interviews with farmers, animal health inspectors and consumers. The results showed us that the KRAV certificated farms used only loose housing barns and that the cattle were allowed a pasturetime of five months, or more, in one year. Our interviews with the consumers confirmed that KRAV was a well known trademark. The conventional farms were more flexible in their choice of housing systems, and used both loose housing barns and barns with the cattle tethered. For those animals the pasturetime in one year were kept down to three to five months. During the interviews with the animal health inspectors it came to our knowledge that they valued elements as long pasturetime and loose housing barns to support the natural behaviors of the animals. These factors also stood well in line with our own conclusions about what would function in a positive way on the natural behaviors of dairy cattle. This was confirmed not only by interviews but also by earlier research. The KRAV certificated farms fulfilled the terms of long pasturetime and loose housing barns in a stronger way.</p>

Climate Change and Agriculture in Babati : Awareness Strategies Constrains

Häckner, Lina January 2009 (has links)
<p>Climate change caused by green house gas emissions, mainly carbon dioxide, is today’s most debated environmental issue. The United Nations Framework Convention on Climate Change, with the legally binding Kyoto protocol, is the emission regulatory framework. Tanzania has ratified both the conventions supporting carbon reductions.</p><p>Tanzania has a very varied climate with two rainfall regimes dominating the country, bimodal and unimodal. Scientific literature predicts a 2,2-4°C average increase in temperature for Tanzania, all studies also predict a higher increase in the cooler period and lower in the warm period. Rainfall predictions are less certain but in general a 10 % average increase is expected but the distribution uneven, both between rain periods and geographically. Tanzanian reports estimate a 5-45 % increase in rainfall in bimodal regions and a 5-15 % decrease in unimodal regions. The distribution of increase in bimodal regions will be uneven, with an increase in the long rain period and a decrease in the short rain period.</p><p>Agriculture is indisputably the most important source of income in Tanzania standing for 80% of employment and 50% of GNP. Climate change will therefore inevitably affect the economy and livelihood of people. Developing countries are also more vulnerable due to lower adaptation capacity. Effects on Tanzania are predicted to be both positive and negative. Maize production, the major staple, is predicted an average 33% decline while cash crops like coffee and cotton are predicted to increase. To be able to adapt there first has to be a perception of need to adapt, adaption strategies then have to be developed and barriers worked through. The purpose of this thesis is to investigate the level of awareness, strategies and barriers existing for adaption to climate change on national, regional and local level, Tanzania nationally and Babati regionally and locally. The research questions are; How do people perceive climate change? What are the strategies for adapting to climate change? What are the barriers for adaption to climate change? At national level policy framework and strategies were used to answer the research questions. At regional and local level a field study was conducted in Babati to answer the research questions at these levels.</p><p>The study showed that Tanzania nationally has declared their conviction in climate change and state that the issue has to be addressed. Agriculture is identified as one of the most vulnerable areas however climate change is not mainstreamed into agricultural and environmental policy framework. In Babati district no policy was found on climate change and official perception varied. Concerns were related to timing and amount of rainfall, the results were the same for farmers. Global climate change was also known for both studied groups and existed as a parallel truth with the local reason for changes. A number of adaption strategies are also identified nationally, both used and potential, where small scale irrigation is the primary adaptive step. Switching to draught resistant crops is also prioritized in the North eastern region. In Babati adaption strategies were promoted, even though there was not a general policy or perception, by officials to switch to short-term crops and planting of trees. Switching cops was also the most commonly used strategy by farmers along with traditional diversification. Nationally a large number of barriers are also identified including, lack of funding, poverty, HIV, lack of infrastructure and analytic capacity. Officials in Babati also mentioned the lack of money, deforestation, lack of clouds, education, irrigation and seeds. The farmers in Babati were not so clear about what they needed to adapt, irrigation, livestock backup, diversification and switching crops were mentioned, not differing much from used strategies.</p>

Besökstudie av I2-skogen i Karlstad : Betydelsen av tätortsnära skog för samhället / Visitor Study of the I2-forest in Karlstad : The Importance of Urban Forest for the Society

Wallquist, Elin January 2007 (has links)
<p>Karlstad kommun vill att Karlstad ska uppnå 100 000 invånare, mot idag dryga 80 000. För att nå dit måste tätortsnära skogar exploateras. För att få reda på hur välbesökta de tätortsnära skogarna är i Karlstad, genomfördes i november 2005, februari, maj och augusti-september 2006 en kvantitativ besöksstudie av I2-skogen i nordvästra Karlstad. I2-skogen är ett tätortsnära område omgärdat av bostäder åt tre håll. I området finns bland annat flera motionsspår, golfbana och skjutbanor. Studien visar att området är välbesökt, ca 180 000 besökare per år. 77 % av besökarna bor i närområdet runt skogen, inom ett avstånd av 500 meter. Boendeformerna i området speglar besökarna och deras aktiviteter och I2-skogen kan kallas för en ”vardagsskog” med besökare som återkommer flera dagar i veckan. Om de tätortsnära skogarna runt Karlstad exploateras enligt kommunens översiktsplan kommer det att påverka invånare som idag bor nära skogsområden till att de får längre avstånd mellan bostaden och skogen. Ett längre avstånd kan göra att det tar för lång tid att ta sig till skogsområden, vilket leder till att antal besök minskar. När människor inte har tid att vistas i skogen ökar stress och ohälsa, även barn påverkas negativt av att inte få leka fritt i en tätortsnära skog. Det är nu läge att inrätta någon form av områdesskydd för vissa av de tätortsnära skogarna runt Karlstad, då de har ett oerhört viktigt socialt värde för befolkningen i Karlstad och därför behöver bevaras för framtiden.</p> / <p>The local authority in the city of Karlstad, Sweden, want the city to increase to 100 000 inhabitants, today it has about 80 000 inhabitants. To reach the goal several urban forests needs to be exploited. To get an understanding of how well visited the urban forest is in Karlstad, a visitor study were made in November 1995, February, May and August-September in 2006 in the I2-forest. The I2-forest is an urban forest surrounded by residences in three directions. In the area there are several trails, a golf court and shooting ranges. The quantitative visitor study shows that the I2-forest is well visited by about 180 000 visitors per year. 77 % of the visitors are living in residence maximum 500 meter from the forest. The different kind of residences in the neighbourhood shows who the visitors are and what activities they are doing. Many of the visitors come several days a week to the forest. If the forests around Karlstad city will get exploited as the local authority want, it will affect a lot of people to get longer distance to a forest from their homes. A longer distance could make it take too long time to get to the forest area and the number of visitors will decrease. When people don’t have time to be in the forest the stress and ill-health will increase, even the children will be affected negatively. Therefore it would be a good idea to establish some kind of reserve in some of Karlstad’s urban forests, to protect them from future exploitations. Because the urban forest have a great social value for the inhabitants in Karlstad and therefore the urban forest need to be saved in the future.</p>

Ekosystemansatsen : på nationell och regional nivå

Walter, Martina January 2006 (has links)
<p>Att bevarandet av biologisk mångfald är en grundpelare för att nå en hållbar utveckling enades världens länder om i Konventionen om biologisk mångfald (CBD) som upprättades under toppmötet i Rio de Janeiro 1992. I konventionen förespråkas den s.k. ekosystemansatsen (EA), vilket är en strategi som innebär en helhetssyn på ekosystem. Syftet med denna uppsats är att undersöka i vilken grad EA tillämpas på nationell och regional nivå. Frågan är också om EA är en bra utgångspunkt för att upprätthålla biologisk mångfald på landskapsnivå samt vad som kan öka tillämpningen av EA på regional nivå. På nationell nivå analyserades två delar i miljömålspropositionen och på regional nivå analyserades de landskapsstrategier som sju län har fått i uppdrag av regeringen att upprätta i ett pilotprojekt. Min teoretiska utgångspunkt har varit ekosystemansatsen och dess principer och vägledande punkter. Metoden bestod av främst en kvantitativ innehållsanalys med kvalitativa inslag och som komplement utfördes fyra intervjuer.</p><p>Resultatet visade att de delar av miljömålspropositionen som analyserades i hög grad följde ekosystemansatsen. En brist i propositionen var dock att det saknades riktlinjer om att det behövdes involvering av olika aktörer när den ursprungliga definitionen av landskapsavsnittet i strategierna skulle bestämmas. Att denna aspekt var implicit ledde troligtvis till det faktum att den även var implicit i landskapsstrategierna. Tillämpningen av EA i landskapsstrategierna skedde, trots att länsstyrelserna endast tillämpade den indirekt, i ganska hög grad och särskilt togs hänsyn till sociala aspekter som involvering av olika aktörer i själva processen och kontakt med vetenskapliga discipliner. Det som däremot var bristfälligt gällde tillämpningen av komplexa aspekter, vilka inte klart hade uttryckts i riktlinjerna till länsstyrelserna från regeringen. Dessa faktorer var beaktande av förvaltning av ekosystem inom ramen för dess funktion, processer i ekosystem samt adaptiv förvaltning. Alla intervjupersoner var överens om att EA är övergripande och ganska luddig, men det måste den vara för att gälla globalt. Av vikt är att konkretisera den på nationell och regional nivå. Ett förslag är att Naturvårdsverket i detta projekt ger tydliga riktlinjer angående tillämpningen av EA i landskapsstrategierna och att det är en tvåvägskommunikation mellan Naturvårdsverket och länsstyrelserna så att det blir en iterativ process. Genom en konkretisering kan tillämpningen av EA öka och därmed ett steg tas mot en hållbar utveckling.</p> / <p>The Convention on Biological Diversity (CBD) promotes the Ecosystem Approach (EA), which is a strategy that endeavours to take a comprehensive approach to managing ecosystems. The aim of this report is to study to what degree the EA is being followed on a national and regional level. A key question of the research is whether EA is conceptually sound and whether it has been operationalised effectively at both national and regional scale. Using articulated EA principles and operational guidelines from the CBD this study analyzed the Government's national environmental directive concerning biodiversity. The same approach was also applied to an analysis of several regional landscape strategies that are being developed as part of a pilot project. The results show that the national biodiversity directive is largely consistent with an EA. Although one area of inadequacy was the level of involvement by different stakeholders in the original decision about defining the landscape area in the pilot studies. This was also a weakness in the landscape strategies- perhaps because communication on this issue was not explicit in the directive from the government.</p><p>The implementation of EA in the landscape strategies at the regional level was also found to be good, especially the participation from different stakeholders (especially local stakeholders) in the process and scientific institutions. However inadequate factors not represented in these strategies were complex ecological aspects such as principle 6 (ecosystem must be managed within the limits of their functioning) and operational guideline 1 (focus on the functional relationships and processes within ecosystems). Adaptive management (operational guideline 3), a relatively new approach in Sweden, was also found to be deficient. All the respondents agreed that the EA needed to be made more concrete on a national and regional level. A suggestion from the research to improve the development and adoption of the EA would be to develop iterative mechanisms between regional and national authorities to ensure national guiding principles are informed by more concrete regional experience. When the EA is implemented more effectively we will take one step further on the way to reaching a sustainable development.</p>

Effect on Climate Change on Maize Production in Zambia

Ngoma, Justine January 2008 (has links)
<p>Maize is one of the crops that is grown by most farmers in Zambia being the staple food for the majority of Zambians. However, despite the crop being so important, its production is dependent on climatic conditions. This means that any change in climate can affect the production either negatively or positively. This research therefore, focused on determining how the change in temperature and rainfall affect maize production on the Copper belt, Eastern, Lusaka and Southern provinces of Zambia and investigate the main adaptation measures implemented by both the government and non-governmental sectors. Also, assess through the review of National Agricultural Policy and action plans, how the government has documented issues of climate change. In order to obtain the needed data, interviews were conducted with different officials from both the government and non-governmental sectors. However, from the estimate of the impact of temperature and rainfall on maize production, the results did not show with any significance that either temperature or rainfall has effect on maize production. In fact, it was found that quantifying the effects of climate change on maize production is not easy due to difficulties in quantifying other factors that may also have large impact on maize production. It was therefore, not possible to conclude whether or to what extent climate change has effects on maize production. However from the interviews conducted, it was found that both the government and non-governmental sectors have introduced different activities in their programmes to ensure that farmers are food secure, though the ministry of agriculture has no policy document on how to handle the problem of climate change to address different issues of the sector. In fact, most offices in the ministry do not have much documented information on climate change which could also be seen from the review of National Agricultural Policy and action plans where climate change issue has not been emphasized. Though both the Government and non-governmental sectors have implemented some adaptation measures, it cannot easily be concluded whether the implemented measures are adequate or not due to the fact that we are not sure of the expected effects in different parts of the country. Nevertheless, to enhance food security with or without adverse effects of climate change on maize production, it was recommended that members of staff at all levels under MACO should be trained in the area of climate change for them to have a wider understanding of the issue and work responsively and that much research should be done to open up the mind of the people and help policy makers make effective plans.</p>
