To develop a sustainable future for the rangelands, partnerships are needed — partnerships between scientists, policy makers, visitors, and most significantly, the various communities of people who live and work in the rangelands. The views of these people are as variable as the country about which they care; rangeland communities are not homogeneous. The power relations between these people are at the base of many conflicts. How we handle the relationships between these groups, and manage these conflicts, are crucial for success in land management. ¶ The first part of this thesis reviews the history of both community participation and power theory. While participatory approaches are part of the rhetoric in Australian land management, proponents are generally naïve about the complexities of power and power relations. The philosophical literature highlights that power is a contested concept; and these divisions are epitomised by the works of Habermas and Foucault. Their writings are compared and contrasted to provide a rich understanding of power relations in community participation. ¶ Power relations influence whose voices are heard: those who exercise power, and the sets of rules that define what is seen as true or false at any given time in history. Power relations also determine whose knowledge is incorporated in land management policy and practice. The model proposed in this thesis demonstrates that power relations interact with every dimension of community participation: context, goals, scale, stage, who is involved, the capacity of those involved, and the methods used. ¶ Research was undertaken within agricultural and natural resource management programs and projects in south-west Queensland. A variety of participatory approaches are used by government agencies to encourage grazier participation and the adoption of more sustainable practices, such as Landcare, Bestprac and the regional groups, such as the South West Strategy. While government staff in south-west Queensland purport to share decision-making power with landholders, landholders tend to have different perspectives about the level of power that is being shared. ¶ One of the key findings of this research is that power is not static within any project. Rather, power is ultradynamic, fluid, and highly dependent on context. In terms of land management programs, the levels of power sharing fluctuate over time and between actors. The micro-physics of power, or the power relations among individuals, are often invisible to, or neglected by, the facilitators of land management programs. ¶ Government agencies tend to focus on the processes used, and on finding the best participatory methods, rather than on the individuals who implement the process or the individuals who participate. Greater flexibility is needed in approaches to land management; correspondingly, greater responsibility is needed from all individuals who have a stake in it. To find sustainable solutions for the rangelands and its people, all involved in participatory land management projects need to better understand the dynamics of power, so as to manage any negative effects.

Ranching communities in Texas have long recognized fee hunting as a natural resource with the potential of directly affecting agricultural incomes. Hunting as an industry today, appears to be developing into an economic substitute for Texas ranchers who are accustomed to the variable nature of agricultural markets. To determine the economic impact of this market relative to its functional utilization by landowners, this research analyzed a large group of landowners in Central and South Texas. Information was collected through a personal interview process of 146 landowners. Data collected primarily related to the individual landowners' specific fee hunting operations and the economics associated with their enterprise operations. Response data was tabulated and examined through use of comparative analysis and bivariate methods when appropriate. Output yielded a descriptive demographic profile of landowners along with landowner opinion/attitude on ensuing constraints and values of enterprise operations. Additionally, costs and returns to operations were summarized through development of an enterprise budget by ecoregion. From this analysis, it became clear that many landowners possess strong 'feelings' about their lands and appear to share parallel ideologies relative to their properties as an earned entitlement and privilege to be passed along to their heirs. However, these Texas ranchers are well aware of the economic pressures under which they must operate and their commitment to sound land management practices increasingly includes wildlife management. This, much in part, is due to the dramatic increase in revenues generated by fee hunting enterprises over the past decade. However, the budget analysis indicates possible constraints when landownership size becomes smaller such as through the sale of parcels for business purposes or through inheritance.

Farming systems are characterized by many attributes. In order to evaluate their overall sustainability, it is necessary to consider all relevant attributes together. This study uses a multiattribute utility model (MAUM) to compare two tillage technologies (conventional tillage versus zero tillage) to draw an inference about their sustainability. On the basis of five cropping systems, two soil landscapes and two tillage technologies, twenty large size farms are used to represent different range of farms in Saskatchewan. A bio-economic simulator is used to estimate stochastic values of the attributes characterizing these farming systems. The data for bio-economic simulator are obtained from Erosion Productivity Impact Calculator (EPIC) and Top Management Farm Business Simulator (TMFBS) models. The MAUM, based on the preferences of the individuals from two groups (Producers and Agrologists), is used to identify the preferred farming systems. Based on the simulated attribute values and their desirability, conventional tillage systems are preferred in the Brown soil zone. In the Dark Brown and the Black soil zones, the results are mixed. In the Gray soil zone, the zero tillage systems are preferred.

The Apollo butterfly, Parnassius apollo, is categorized as Near Threatened (NT) in IUCN Red List. Today in Sweden it is found only in strongly fragmentized populations. In the county of Stockholm, P. apollo exists exclusively in some islands of the archipelago and with one mainland population in Stora Vika. This study has the purpose of expanding the knowledge of the local conditions for the butterfly in the south parts of the county of Stockholm and thereby contributes to a sustainable land management that can preserve the Apollo butterfly. A comparative study was done between areas where the butterfly today have: a stable population (Stora Vika, Utö and Ålö), has disappeared (Muskö and Yxlö) or is strongly declining (north part of Ornö). The investigation was based on factors that was considered be contributing to the species decline. Factors that was investigated was the general distribution of host-plant S. telephium, overgrowth in rocky outcrops, presence of nectar plants close to host-plants and if a large proportion of forest in the surroundings of the investigation sites could have a isolating impact on sites. The study was based on 10 sites where the butterfly exist, 7 sites where it has disappeared and 3 sites where it has declined. No significant differences could be found for any factor. On the contrary, the general presence of host-plants at rocky outcrops seems to be the same in areas where the butterfly has disappeared as in areas where it exist today. However caterpillars were only found at sites with a wide distribution of host-plants and also at sites with a large proportion of forest in the surroundings. This was speaking against the hypothesis that a large proportion of forest could have an isolating effect on sites and therefore a negative impact on the adult butterfly preferences. The result creates new questions and the conclusion is that more knowledge of the local conditions is needed to ensure good practice in land management. Sites which are today hosted by the caterpillar should be identified, investigated and protected. Furthermore should the dispersal of nectar plants be investigated and it would be interesting to study the effects of limestone by analyzing and compare Cd concentrations in S. telephium from Muskö with plants from Stora Vika, Utö and Ålö.

The socioeconomic context of many biodiversity rich countries is argued to be heavily dwarfed in current conservation and development debate, resulting in that projects that intersect complex issues of development and conservation are often simplistically deemed as being unsuccessful. The aim of this research has therefore been to attain a more profound understanding of how socioeconomic conditions and local neoliberal contexts effect ICDP projects and to an extent also agroecological transition. In this case study ten qualitative life-story interviews were carried out during a minor field study in rural Las Pavas, Nicaragua. These were further analyzed through the use of the sustainable livelihood approach in order to identify what impacts the local socioeconomic contexts had on participant livelihoods and also what prospects and challenges C.I.P.P’s permaculture project presented in this regard. The empirical evidence shows that participant livelihoods were subjected to several constraints that were buttressed by the neoliberal development context which signified a great reliance on cattle raising as main financial activity at the expense of other important natural assets such as forest and water. Furthermore, demonstrating that permaculture projects had to provide the widest range of benefits with the least amount of risk in order to be adopted.

The purpose of my work is to make the theoretic generalization of lands estimation, to analyse the device of wholesales estimation and the chance of using that device in cadastre. In my work was inspected the national and wholesales estimation, and descripted methods and criterions of estimation. I inspected the difference and analogy between estimation method in Lithuania and in some countries of Europe union. I make the database of lands plot for Klaipėda town, using GeoMap2004 software. This database is available, for accumulation, editing and analysing of lands plot.

This work includes experimental examination of the hypothesis, affirming that bacteria’s, oxidising iron and manganese can grow in some Lithuanian water treatment and can increase the removal of iron and manganese substances from the water. The novelty is that the method of identification and cultivation of iron bacteria’s presented in the foreign scientific publications was improved and adapted to research of such micro-organisms existing in the quartz sand filter media in the Lithuanian equipment of water treatment plant. For the first time in Lithuania there was examined quantitative distribution of iron and manganese oxidising micro-organisms in the sand thin coating in filters of drinking water purification and were found regularity and dependency of iron bacteria’s activities on the main technological parameters in removal of iron and manganese substances from the water.

Iron and manganese – the main components in Lithuanian groundwater, not following requirements of norms regulate the water quality. Now the most advanced method for removal of the mentioned substances is non-reagent technologies, where the important role is the on biological oxidation.

During the land reform there where established a lot of farms, composed of few plots. On purpose to withstand the competition, its essential to enlarge plots, and makes better conditions for farming. Rational land use is possible only if farm uses compact and comfortable land tenure. It is necessary to stimulate early retirement from farming, which may influence better farms economical structure. Stimulation of farm enlargement, consolidation of plots will improve competitiveness and economical efficiency of other farms. The purpose of research – to investigate the formation of farmers farms in the Anyksciai district and to estimate current situation. The object of the research - farmers farms of Anyksciai district. The analysis of farms size and the peculiarity of farmer’s farms were accomplished. It was established how farmers farm number changes in Anyksciai district, and researched their farm areas of crop. In this master work was analyzed farmer farm registry trim and analyzed their maintenance possibilities. During the scientific research was analyzed scientifics works, lows, low acts, witch have connection with this work. Data is analyzed in literary way and statistical designed calculation method.
