The diploma thesis is focused on the analysis of the damages which were caused by wild boar on farming plants in the region of Milevsko. Three areas of interest were chosen for the observation (the area around Sepekov, Přeštenice and Opařany). Each of the areas of interest observed was chosen because of its conditions suitable for the occurrence of wild boar during whole year. Each area had also ideal conditions for evaluating of the damages caused by this species on farming plants. The main aim of this diploma thesis was appraisal of the damages caused by wild boar according to the most suitable Czech and foreign methodologies. The observation was realized in the period from the beginning of February 2011 to the end of October 2011. The size of the damages on particular farming lands was measured according to three Czech methodologies (according to Dvořák et al., 2006). Total evaluation of the damages caused by wild boar on farming plants was realized according to Czech methodology by Kamler and two foreign methodologies (by Jonathan Yoder and Ray T. Sterner). The biggest damages caused by wild boar were found out in the area around Sepekov. The most attractive and also the most damaged farming plant was maize in the region of Milevsko. The damages of permanent grass cover caused by rooting of wild boar were found out only in spring term. Winter grains were mostly damaged by wild boar in the period of milky ripeness. In case of the usage of the methodologies for finding out the amount of damaged area it was necessary to choose the methodology according to the kind of a farming plant, the height of a plant and the kind of the damage. All three types of the methodologies used for finding out the total amount of damages caused by wild boar on farming plants were very exact and applicable to the chosen region.

The focus of this research has been on how the county of Hertfordshire negotiated the economic, social and political changes of the late nineteenth century. A rural county sitting within just twenty miles of the nation’s capital, Hertfordshire experienced agricultural depression and a falling rural population, whilst at the same time seeing the arrival of growing numbers of wealthy, professional people whose economic focus was on London but who sought their own little patch of the rural experience. The question of just what constituted that rural experience was played out in the local newspapers and these give a valuable insight into how the farmers of the county sought to establish their own claim to be at the heart of the rural, in the face of an alternative interpretation which was grounded in urban assumptions of the social value of the countryside as the stable heart of the nation. The widening of the franchise, increased levels of food imports and fears over the depopulation of the villages reduced the influence of farmers in directing the debate over the future of the countryside. This study is unusual in that it builds a comprehensive picture of how agricultural depression was experienced in one farming community, before considering how farmers’ attempts to claim ownership of the ‘special’ place of the rural were unsuccessful economically, socially and politically. Hertfordshire had a long tradition of attracting the newly wealthy looking to own a country estate. Historians have suggested that in the late nineteenth century there was a shift in how such men understood ownership of these estates, showing little enthusiasm for the traditional paternalistic responsibilities; in the face of a declining political and social premium attached to landownership, their interest lay purely in the leisure and sporting opportunities of the rural. However, as this research will show, the newly wealthy were not immune to that wider concern with social stability, and they engaged with their local environment in meaningful ways, using their energies and wealth to fund a range of social improvements. This research extends our understanding of just how the rhetoric of the rural was experienced by the residents of a county which so many saw as incorporating the best of the ‘south country’. In so doing, it makes a significant contribution to our knowledge of how this period of agricultural depression was interpreted by the wider nation, and the impact on social and cultural understanding of the place of the countryside within the national identity.

Like other countries of the world, Costa Rica faced the challenge of dealing with a variety of trade-offs when implementing sustainability goals in agriculture. Very often, economic promotion is in conflict with goals regarding human and environmental health protection. Organic farming practices could provide strategies to overcome some of these trade-offs. However, in Costa Rica, the majority of farmers still relies on conventional farm practices. In this paper, I investigate the potential for a sustainable transformation in Costa Rica’s agriculture by focusing on organic farming policies. I shed light on the role local actors and organizations play in this process compared to other actor types. I argue that local actors are “the agents of change” in these processes, as these are the target groups of organic farming policies and are the ones who are asked to change their farm practices. Based on survey data and network analysis, I was able to illustrate how differently integrated local actors are compared to other actor types in Costa Rica’s implementation of organic farming policies. Local actors show interest and willingness to further participate in land-use implementation processes when institutional barriers are alleviated, and further promotion instruments are available.

On the frontier of biodiversity-rich tropical forests, how land is used has an important role in buffering the primary ecosystem. Unsustainable small-scale cattle farming endangers soil quality and degrades the landscape. Silvopasture is a type of agroforestry that provides both ecological and livelihood benefits. A number of projects have been implemented across the tropics to encourage silvopasture adoption, with varying success. This dissertation questions the reasons for variable outcomes among participants within these projects: what motivates smallholders to adopt innovative land-use practices, and what form of incentives may help to overcome obstacles and catalyse adoption. This dissertation contributes to the ongoing debate on payments for ecosystem services, specifically about their suitability and effectiveness. To understand what influences decisions to adopt sustainable land-use practices, I review systematically and quantitatively the literature on adoption predictors, and I empirically analyse participation and short-term adoption in a pilot project for planting fodder trees in the border of a protected forest in Chiapas, Mexico, using primary and secondary data. I focus on subjective perspectives and livelihood strategies of actual and potential participants as explanatory variables, which have received unduly scarce attention in past studies. This lack of attention is partially caused by the difficulties of operationalising internal variables. I address this challenge by developing an analytical approach that increases the precision of the resulting perspectives in Q methodology. I cluster livelihood strategies and model adoption. This in-depth case-study suggests the type of incentives that are adequate to encourage adoption of sustainable land-use practices. Results indicate that payments may not be the best incentive for pioneer adopters, and that the adoption process is composed of separate individual steps, which are influenced distinctly by identifiable predictors, such as livelihood diversity. Uncovering this heterogeneity of motivations towards adoption provides useful knowledge for designing more effective external policy interventions.
