För att kunna sträva efter en hållbar utveckling och lämna över en god miljö till nästa generation krävs ett samordnat arbete kring de källor som utgör påverkan på naturen och miljön. Jordbruket är en sektor som påverkar naturen och miljön genom dess näringsläckage till mark och vatten.  För att minska näringsläckaget krävs styrmedel som har till syfte att effektivisera för ett mer hållbart jordbruk. Greppa Näringen är ett tyrmedel i Sverige som startades som ett projekt för att stoppa framförallt utlakning av kväve från svenska åkermarker. En bättre förståelse av vad som ligger bakom lantbrukares val att inte ansluta sig till Greppa Näringen är avgörande för att kunna designa ett optimalt program anpassat för lantbrukarna. Denna studie har genomförts utifrån kvalitativa intervjuer för att identifiera faktorer och bakomliggande aspekter som ligger till grund för att lantbrukare inte väljer att ansluta sig till Greppa Näringen. Fem lantbrukare har intervjuats och de faktorer som har identifierats är kunskap, engagemang, tid, förtroende, påverkan utifrån och ekonomi. De mest betydande aspekterna som lantbrukarna nämnde var att verksamheten inte är relevant för Greppa Näringen (kunskap), att lantbrukarna har prioriterat annat inom verksamheten (engagemang och tid) samt att lantbrukarna inte tar till sig den informationen som Greppa Näringen ger ut (engagemang). Faktorerna ekonomi och påverkan utifrån har endast nämnts av en lantbrukare. / n order to strive for a sustainable development and hand over a good environment to the next generation, a coordinated work requires on the point- sources that has great impact on nature and the environment. The agriculture is a sector which has great impact on nature and the environment through its leaching of nutrients to soil and water. To reduce the leakage of nutrients, a set of instruments is required. Instruments, which aim to improve the efficiency of a more sustainable agriculture. Greppa Näringen is an instrument in Sweden that started as a project to mainly stop the leaching of nitrogen from Swedish arable land. A better understanding of what is behind farmers' decision not to participate in Greppa Näringen is crucial to be able to design the most ideal program adapted for the farmers. This study has been conducted from qualitative interviews to identify the factors and underlying aspects that explain why farmers choose not to participate in Greppa Näringen. Five farmers were interviewed and the factors that have been identified are, knowledge, commitment, time, trust, influence from the society and economy. The most commonly mentioned aspects were; that the farm is not of relevance for Greppa Näringen (knowledge), that farmers have prioritized other things within the farm (commitment and time) and also that farmers do not adopt information from Greppa Näringen, even though it is presented to them (commitment). The factors economy and influence from the society has only been mentioned by one of the farmers.

Wetlands are commonly known for providing a number of key functions. In the context of Swedish agricultural landscapes, the ability of wetlands to enhance nutrient retention and provide habitats for biodiversity has long been recognized. Nevertheless, many wetlands in Sweden have been lost or damaged due to drainage activities, and there is a need for scaling up the implementation of wetlands. The possibilities to reach wetland implementation goals in Sweden highly depend on voluntary participation by farmers and landowners. In order to enable and encourage landowners and managers to create and manage wetlands, the access to information, support and advice is considered to be vital. One way to provide support is through farm advisory services, such as the project ‘Greppa Näringen’ (GN) in Sweden, in which advice on, among other things, wetland creation and maintenance is offered. However, to date there is relatively little research on how such advisory systems work in practice and what potential barriers there are to their success. This thesis aims at investigating how wetland advisors perceive their role in enabling and encouraging landowners in wetland implementation. It also aims at revealing what barriers the advisors experience and what potential improvements they believe are necessary in order to aid them in their mission and, in turn, promote wetland implementation. This is achieved by conducting semi-structured interviews with 14 wetland advisors within GN. The findings are then analyzed in relation to ideas on knowledge, motivation, dialogue, mutual learning and trust, which previous scholars have identified as key components in the interaction between advisors and farmers. The results show that the wetland advisors draw and refine their knowledge from an array of sources, such as written articles and reports, interaction with other stakeholders, and personal experience of wetland creation and maintenance. Moreover, in their mission to enable and encourage landowners and managers in wetland creation and management, the wetland advisors are required to consider a number of aspects, including landowners’ interests, opportunities for financial support, and environmental conditions. The establishment of relationships between advisors and landowners is of utmost importance, in which dialogue, respect, mutual learning and trust are key components. Furthermore, the study reveals a number of barriers and potential improvements. These regard the need for a longer support-chain, less complex and more reliable systems for financial support, more coherent administrative processing of notifications and permits, and more knowledge and experience on handling opposing interests. It is also vital to further acknowledge wetland functions beyond the current focus on nutrient retention in both financial support systems, research and focus areas within the advisory system of GN, and, finally, to further communicate the opportunity to receive wetland advice both within and beyond GN. This could aid advisors in their mission to transfer knowledge to landowners as well as heighten the quality of the advisory visits, and in turn motivate more landowners and farmers to participate in the implementation of long-term sustainable wetlands in Sweden.
