Measuring Poverty and Wellbeing: Applications for Land Management

Rosato Larrauri, Melissa January 2013 (has links)
Poverty reduction and conservation can seem contradictory as integrated goals. Despite mixed results over the past several decades, both goals are increasingly being sought out together in practice. Using a case study of an integrated conservation and development project in the Azua province of the Dominican Republic, this thesis examines the definitions and measurement of poverty and wellbeing within integrated conservation and development initiatives. It asks whether the inclusion of subjective ideas and participatory approaches may present new opportunities to better integrate poverty measurements within natural resource initiatives. Four focus groups and 250 questionnaires formed the core methods for data collection. The study reveals wellbeing as a concept was better able to capture the multi-faceted nature of capabilities poverty. Wellbeing often engages with the themes of vulnerability and inequity and includes politically-sensitive considerations instead of concepts that are about assets or consumption, ideas based in the outdated income-poverty perspective. Locally developed indicators were best able to reveal nuances related to context that universal poverty indicators would miss or misrepresent. The results also found that the way poverty, wellbeing, problems and solutions are conceptually framed and defined can be highly relevant. Using asset-based concepts and metrics would lead to economic development goals whereas rights-based ideas would promote very different objectives and methods. The comprehensive identification and targeting of stakeholders was found to be a necessary focus in determining the priorities. Participatory processes, especially with a commitment to power devolution, can help ensure that an array of local ideas are accounted for, and contribute to, a nuanced understanding of complex phenomena. Overall, subscribing to a rights-based approach that targets the means (opportunities) of development and not the ends (assets) can facilitate the needed shift towards the new poverty paradigm, in both concept and practice. A more successful integration between poverty reduction and conservation will require such a shift.

It's for love not money: Queensland graziers' perceptions of sustainable development

Jennifer Moffatt Unknown Date (has links)
Despite a National Strategy for Ecologically Sustainable Development and the embodiment of this in numerous national and state statues, environmental degradation continues to occur on rural land. This raises the question of how the primary land managers in Queensland perceive sustainable development. Australia’s early reliance on agricultural production and international markets contributed substantially to the extensive environmental degradation that has occurred. Consequently economic and environmental issues have dominated the research on sustainable development, with the social dimension relatively neglected. In addition, despite the large quantity of work that has been conducted with farmers and graziers, little is known about how either of these types of land managers interpret sustainable development. The aim of this thesis was to develop an in-depth understanding of graziers’ perceptions of sustainable development to make a contribution to this area. An exploratory interpretative approach was taken to conduct this investigation because previous research had been limited. In-depth unstructured interviews were conducted with 57 Queensland graziers in the tropical savannas in a case study with two locations – the Gulf of Carpentaria and the Central West. This approach was supported by participant observation and a brief questionnaire to provide background information. The fieldwork was conducted over a period of five months which allowed analysis to be conducted as the study progressed. Most of the graziers were interviewed on their properties with the goal of adding richness to the data and assisting with interpretation. Several bodies of literature have been used to interpret the results of this study. Areas of the sustainable development literature relevant to this thesis are reviewed to provide a context for the thesis. The literature on structural change in Australian agriculture provides a background to the broad influences on the agricultural sector and farmers. Also reviewed are the approaches taken to change the land management practices of farmers. The enduring value of farming and the changing values of rural land use are explored through a review of agrarianism, the goals and values of farmers and the post-productivist transition. The results for both study locations showed that these graziers preference the economic dimension of sustainable development over the environmental and social dimensions. The rationale for this preference is that maintaining economic viability will allow them to achieve their social goal – to continue their preferred way of life. A strong focus therefore, is on economic viability as a means to a social end. The objective is to overcome the constraints of being market and season dependent and the costs of operating in rural and remote locations through a whole-of-enterprise business management approach. The need for graziers to continue increasing their productivity to remain economically viable and to continue being competitive in international markets, challenges their ability to balance the economic and environmental dimensions of sustainable development. For some the environmental dimension of sustainable development may be compromised to accommodate their economic priorities and social goals. A perceived future threat, more so for Gulf graziers, arises from the belief that they and their interests are marginalised through consultation processes. This contributes to their belief that the government prioritises Aboriginal land rights and environmental protection interests over their production interests. They believe that if this continues their future is at risk through further decreases to the security of their tenure. The results of this study suggest that a more innovative and integrated approach will be required to meet the challenges of sustainable development in these areas, in early twenty-first century Australia. The holistic approach from a social science perspective has provided an understanding of what graziers value and why. These insights contribute to knowledge of how to progress sustainable development. They could be tested with other types of land managers and as a foundation on which to build a more comprehensive understanding of sustainable development.

Understanding stream incision, riparian function, and Indigenous knowledge to evaluate land management on the Prairie Band Potawatomi Nation

Mehl, Heidi Elizabeth January 1900 (has links)
Doctor of Philosophy / Department of Geography / Marcellus Caldas / One of the critical challenges facing our world today, is managing our intensive use of land to support a growing population, while also ensuring the continued provision of ecosystem services that have supported human civilization thus far. The Great Plains region is representative of this complex global challenge because it supports some of the most productive agriculture in the world, yet is also degraded by land cover change, habitat loss, and nonpoint source pollution from nutrients, sediment, and pesticides. In the absence of regulatory remedies, nonpoint source pollution is typically addressed through voluntary adoption of Best Management Practices (BMPs). However, meaningful reductions in nonpoint source pollutants are too often elusive. This is due to two overarching factors: variable rates of effectiveness based on site-specific, geographic factors; and variable rates of adoption due to social, economic, and policy pressures. Therefore, to address the problem of nonpoint source pollution, we must better understand the interacting physical processes behind nonpoint source pollution, and the cultural processes driving land management choices. The unifying variable between rates of effectiveness and rates of adoption, is land use/land cover (LULC) driven by land management practices. This dissertation seeks to integrate an advanced understanding of the interactions between the physical impacts of LULC on nonpoint source pollution removal in stream riparian zones, with an evaluation of Indigenous cultural frameworks to better inform land management paradigms. This dissertation explores the relationship between fluvial geomorphology, hydrology, and nutrient dynamics in riparian areas of incised stream channels. To add to this understanding, I utilize a transect of nested piezometers to observe riparian zone hydrology under both forested and row-crop land cover along an incised stream, James Creek in northeast Kansas. The investigation of coupled hydrologic/biogeochemical relationships addresses whether precipitation interflow to incised channels is interacting with the soil in such a way that denitrification processes are facilitated, or inhibited. These issues may be better addressed through multiple BMPs and management for whole ecosystems – a view that is contained within the Traditional Ecological Knowledge (TEK) framework. Understanding Indigenous values and land management preferences may provide an alternative cultural framework for valuing native land cover, and help government agencies and NGOs promote increased adoption of BMPs. A greater understanding of these Indigenous cultural frameworks will also help to bridge gaps in understanding between government agencies and Indigenous tribes in questions of resource management. Therefore, this dissertation examines Indigenous governance of natural resources, and historical barriers that have led to the unique situations that exist today. Utilizing mixed-methods research, the overarching goal of this dissertation is to apply advanced understandings of riparian hydrology and water quality function in the Great Plains to best management practice recommendations based on a sound understanding of Indigenous nature-society value systems.

Development opportunities in the land management process in Rwanda : In order to achive a more effective and efficient land use

Ericsson, Elin, Lindberg, Albin January 2018 (has links)
A well-functioning property system is a criterion for a country to have good opportunities in social development. This study looks into one of the development opportunities in Rwanda’s real estate system, especially the provision and the updating of the country’s management in the land use process. The problems in Rwanda are described as a combination of lack of communication and knowledge from the authorities and the population. The methods in this study conducted of a qualitative interview combined with a literature review. This in order to gain the fact needed to answer the research questions of this study were the aim was to find some difference between the Master Plan and the physical reality and suggestions in how to establish effective and efficient land use in Rwanda. At first the study aimed to perform a comparative analysis but while performing the methods it was showed that the comparison method was impossible to go through with, instead the study got depended on a literature review along with interviews to be able to answer the research questions of the study. The results from the methods are presented in two steps, first the results from the interviews and then is the results from the literature review presented. The different interviews gave similar results in four main categories which made the conclusion obvious. The land use planning law needs to be reviewed and that the Ministry of Lands and Forestry have a lack of concrete tolls and power to prevent illegal land use.

Soil chemical and nutrient uptake dynamics of maize (Zea mays L.) as affected by neutralization and re-acidification after liming

Jansen van Rensburg, Hester Getruida 06 June 2010 (has links)
An imperative of the South African government is to increase agricultural production in rural areas. In support of this, a project was initiated in the Mlondozi district of Mpumalanga Province under the National LandCare programme. The goal was to assess land management practices contributing to sustainable and profitable agricultural production. Medium-term liming experiments were sampled to a range of lime treatments in a Hutton and Oakleaf soil. Critical thresholds where a reduction in relative grain yield was found were at a pH (H2O), extractable acidity, Al and acid saturation of 5.49, 0.277 cmolc kg soil-1, 0.145 cmolc kg soil-1 and 13%, respectively. Critical soil fertility threshold levels were established at 50 mg K kg-1, 228-345 mg Ca kg-1, 78-105 mg Mg kg-1 and 1.68-2.83 mg Cu kg-1. Nutrient vector analysis showed a toxic build-up of Fe, followed by Al and to a lesser extent Mn, which depressed the uptake of Ca, Mg and B in the Hutton soil. In the Oakleaf soil, Al toxicity, followed by high concentrations of Mn and Fe, markedly reduced the uptake of Ca, Mg and K by maize. Net rates of acid production in the soil profile varied between 1.61 and 2.44 kmol H+ ha-1 year-1 for the Hutton soil and between 4.59 and 8.82 kmol H+ ha-1 year-1 in the Oakleaf soil due to liming. A decline of 0.046 pH unit year-1 for an initial pH(H2O) value of 5.33, and 0.140 pH unit year-1 for an intial pH(H2O) of 6.47, respectively, in the Hutton was recorded. For the Oakleaf these declines were 0.044 and 0.110 pH unit year-1, from pH(H2O) 4.54 and 5.15. Maintenance liming amounts at different pH values for the Hutton soil were equivalent to 0.2, 0.3 and 1.4 tonnes CaCO3 ha-1 annually, while 0, 0.8 and 0.8 tonne CaCO3 ha-1 annually were recorded for the Oakleaf soil. The study was extended to 80 random topsoil samples in the district. Relationships of soil BC over limited pH ranges showed that at soil BC (pH<4.5) the main buffering mechanism was extractable Al > organic C > clay. At soil BC (pH4.5-6.5) the buffering mechanism was extractable Al > clay > CBD-Al > organic C > CBD-Fe. The main buffering mechanism between pH 6.5-8.5 was clay > CBD-Fe, organic C > CBD-Al. Acid production for 30 crop production sites varied from a measured 0.21 to 10.31 (mean 3.70) kmol H+ ha-1 year-1 The rate of pH decline for the top 0-250 mm depth was between 0.051 and 0.918 (mean 0.237) pH units year-1. In the absence of remedial lime applications, pH (H2O) values in most of the area are projected to decrease to the critical value of 5.68 or lower within 4 years. Soil with a pH (H2O) value of >5.73, extractable Al and acidity of <0.18 and <0.25 cmolc kg-1 soil, respectively, clay content of ≤26%, and a ECEC value of ≤3.29 cmolc kg soil-1, are at greater risk of acidification as gradual acceleration in soil acidification takes place at the above-mentioned critical thresholds. / Thesis (PhD)--University of Pretoria, 2010. / Plant Production and Soil Science / unrestricted

A Comparison of Indigenous and Western Land Management; Case Studies of Ngāti Whātua Ōrākei and the East Bay Regional Park District

Jensen, Kyle 01 January 2017 (has links)
Western value systems and ways of knowing the world are in need of serious critique, especially in terms of colonialism and capitalism. These systems, many argue are fundamentally unjust and unsustainable while also working toinvalidate and erase alternative, indigenous ways of knowing. We need to work towards decolonization by both challenging these dominant Western systems, and exploring and supporting alternatives. That the primary intent of this thesis, which aims to engage and compare indigenous and Western worldviews using two specific case studies of land management. The first, Ngāti Whātua Ōrākei, represents an indigenous Māori approach in a New Zealand context, while the East Bay Regional Park District represents a ‘conventional’ Western approach in a US context. The analysis of these groups was based primarily on management plans and other assorted documents, as well as personal experience working with Ngāti Whātua Ōrākei in particular. The structure and practice of each group were explored separately, and connected with the systems and values of their respective cultural contexts. Comparisons were then made exploring differences in community participation, ways of knowing, and systems of values and belief. The District, while showing significant concern for the environment, was still engaged in limiting and harmful colonial practice. In contrast the practice of Ngāti Whātua Ōrākei, with its local focus, community engagement, and deep relation with the land, is a worthy source of inspiration in moving towards a world that is more safe, just, and sustainable.

Evaluating Relationships of Knowledge, Attitudes, and Perception Between Ranchers and Bureau of Land Management Professionals

Garn, Calee L. 01 December 2019 (has links)
The Bureau of Land Management (BLM) manages approximately 245 million acres in the U.S., the majority of which are in the western half of the country. There have been several conflicts in Nevada, Oregon, Utah, and Arizona, since 2010 that have resulted in a fatality, armed militias, several incarcerations, and lawsuits facing the federal government. Following a preliminary needs assessment conducted in Box Elder County, Utah, and a comprehensive review of the literature, further research was needed to understand BLM professional (BLM managers or BLM specialists) and rancher perceptions regarding BLM policies and procedures. The study specifically looked at attitudes, perception and knowledge concerning the implementation of range improvement projects to potentially address conflicts and relationship issues between ranchers and BLM professionals. A needs assessment model was used to frame the research. Two similar questionnaires, one for BLM professional and the other for permitees (ranchers) using federal land managed by the BLM, were developed by the researcher. The questionnaire was divided into four sections: participant characteristics; perceptions concerning BLM policies; knowledge questions related to BLM policies; and attitudes concerning federal land ownership and BLM policies. The rancher questionnaire was mailed to 182 ranchers and netted a 37.2% response rate. The BLM questionnaire was emailed to 15 BLM professionals in the Salt Lake Field office and netted an 84.6% response rate. Results were analyzed using descriptive and appropriate correlation statistics. Multiple relationships between rancher and BLM professionals’ perceptions and knowledge were identified. Rancher interventions should include (a) when to submit rangeland improvement projects, (b) what could result in a temporary reduction in AUMs on a grazing allotment, (c) where to access online NEPA documents, and (d) who makes final land management decisions for the BLM. BLM professionals’ interventions could include the steps required for planning a juniper removal project, and when to submit a new waterline or fenceline request. Ranchers’ background has minimal influence on their perception. Rancher age had a medium, positive relationship on ranchers’ attitude regarding the NEPA process working and needing no revisions. Finally, the majority of rancher respondents identified as somewhat agreeing, somewhat disagreeing, or strongly disagreeing with the federal government owning land.

Responses Of Small Rodents To Restoration And Management Techniques Of Florida Scrub At Cape Canaveral Air Force Station, Florid

Suazo, Alexis 01 January 2007 (has links)
Proper habitat management is essential for the survival and reproduction of species, especially those listed under state or federal laws as endangered, threatened or of special concern, and those with small local populations. Land managers use a combination of mechanical cutting and prescribed burning to manage and restore degraded scrub habitat in east central Florida. This approach improves habitat for the endangered Florida scrub-jay (Aphelocoma coerulescens), but little is known about its effects on other taxa, especially the threatened southeastern beach mouse (Peromyscus polionotus niveiventris). This single species approach may not be beneficial to other taxa, and mechanical cutting and prescribed burning may have detrimental effects on P. p. niveiventris. To evaluate the effects of land management techniques on P. p. niveiventris, I live trapped populations at Cape Canaveral Air Force Station near Titusville, Florida during 2004-2005. I evaluated the relative abundance and related demographic parameters of small mammal populations trapped in compartments under different land management treatments, and investigated the relationship between Florida scrub-jay breeding groups using these compartments and abundance of southeastern beach mice. My results suggest that P. p. niveiventris responded positively to prescribed burning, while the cotton mouse (P. gossypinus) responded positively to the mechanical cutting. Reproduction and body mass of southeastern beach mice were similar across land management compartments. Abundance of Florida scrub-jay breeding groups and southeastern beach mice were positively correlated suggesting that both listed species benefited from the same land management activities. A mosaic of burned and cut patches should be maintained to support small mammal diversity. In addition, adaptive management should be used at CCAFS to understand how small mammals, particularly the southeastern beach mouse, respond to land management activities.

Characterization and communicative analysis of wildlife managers and recreational users of Virginiaâ s Wildlife Management Areas

Carrozzino-Lyon, Amy L. 20 June 2012 (has links)
The Virginia Department of Game and Inland Fisheries (VDGIF) manages wildlife management areas (WMAs) to provide wildlife habitat and hunting and fishing opportunities, along with opportunities for compatible wildlife-related recreation. Despite having responsibility for managing 39 WMAs, comprising more than 200,000 acres, VDGIF had only anecdotal information about who recreated on Virginia's WMAs, to what extent, and how they felt about management of the WMAs. My goals were to (1) determine the types and amount of recreational use WMAs receive, (2) describe and compare VDGIF managers' and WMA users' current attitudes and perceptions toward land management, and (3) determine if a methods bias existed between surveys administered online and through U.S. mail. I observed diverse recreational use totaling > 90,000 annual recreational user days on the 10 WMAs included in the study. Most visitors were satisfied with their visit, agreed with the use of most land management practices presented, and were willing to continue to visit a WMA if an annual fee was imposed. Co-orientation analysis revealed low agreement and low accuracy, suggesting a need to improve awareness and recognition of managers' and stakeholders' attitudes toward land management. Addressing areas where agreement already exists, but may not be recognized, should be a top priority. Areas of greater disparity will prove difficult to address, but attention is critical to successfully implement WMA management objectives. Wildlife value orientations differed between VDGIF managers and WMA users; VDGIF personnel were predominantly Utilitarian (54%, n=35), whereas WMA users were predominantly Pluralist (63%, n=381). Value orientations did not relate strongly to opinions of land management. Demographics differed between web and paper respondents, with slightly younger, more urban and more educated respondents electing to complete the web-based survey more often. Value orientations toward wildlife and attitudes toward land management did not differ between web and paper respondents, suggesting little influence of values and attitudes on the survey mode selected. Increasingly diverse stakeholders and limited funding sources continue to challenge state wildlife agencies. Specific engagement techniques should strengthen interpersonal relationships and collaboration between the agency and its stakeholders. / Ph. D.
