One Health approach to measure the impact on wellbeing of selected infectious diseases in humans and animals in Zambia

Schaten, Kathrin Maria January 2018 (has links)
This study describes the results of a cross-sectional survey conducted in Mambwe district in the Eastern Province in Zambia. It uses a One Health approach to assess the impact of veterinary, medical, environmental and social determinants on animal and human health and wellbeing. One Health is defined as a holistic and interdisciplinary approach that describes the complexities between people, animals, the environment and their health. Human wellbeing is defined in this thesis as 'a condition in which all members of society are able to determine and meet their needs and have a large range of choices to meet their potential' (Prescott-Allen, 2001). As a first step, eight focus group discussions with the inhabitants followed by key informant interviews with stakeholders in the area were conducted to give a primary impression and narrow down the problems in relation to animal and human health of the area in general. Following this, a randomized selection of 210 households was visited and in each household blood samples were taken from all humans and all animals belonging to five animal species, namely cattle, goats, sheep, pigs and dogs. A third of the households did not keep any of the animal species chosen for sampling, but their inclusion was important for the social analysis. In all of these 210 households a wellbeing questionnaire was administered and, for every human and animal sampled, a health questionnaire. The study area falls within the tsetse-infested region of Zambia. It has a high wildlife density reflecting the proximity of several national parks and is historically endemic for both human and animal African trypanosomiasis (HAT&AAT). Therefore humans and animals were tested for trypanosomiasis using internal transcribed spacer (ITS) polymerase chain reaction (PCR). Since it is important as a differential diagnosis, malaria was tested for by a rapid diagnostic test in the field from human blood. Sera from mature individuals from all animal species except pigs were tested in a field laboratory for brucellosis using the Rose Bengal test. Additionally, cattle and dogs were tested for five genera of tick-borne infections (TBI) including Anaplasma, Ehrlichia, Theileria, Babesia and Rickettsia using reverse line blot (RLB) in the laboratory at the University of Edinburgh (UoE). The blood samples for PCR and RLB analysis at UoE were stored on WhatmanTM FTA cards. A total of 1012 human samples were tested for HAT and none found positive. 1005 (seven people had been tested positive or treated against malaria shortly before the sampling) people tested for malaria showed an overall prevalence of 15% (95% CI 13.2-17.7). None of the 734 Rose Bengal tests showed up positive for brucellosis. The prevalence of AAT in 1275 samples tested was much lower compared to former samplings; in cattle 22% (95% CI 18-27.2), in goats 7% (95% CI 4.5-9.2), in pigs 6% (95% CI 3.2-9.4), in dogs 9% (95% CI 5.2-13.6) and no samples were found positive in sheep. The prevalence of TBIs is much more complex with many multiple infections. A total of 340 cattle and 195 dogs were tested. In cattle the number of samples positive for any microorganism was as follows; 92% (95% CI 88- 94.2). Overall there were fewer positive samples from dogs with 25% of animals infected (95% CI 19.2-31.8). The wellbeing and health questionnaires were designed to help to identify possible risk factors for the above-mentioned diseases and signs, such as fever, diarrhoea and seizures, indicative for several other diseases. The results of these surveys might also help to identify potential reasons for a lower or higher prevalence of trypanosomiasis and malaria found than expected from previous studies. Additionally, information on personal happiness, attitudes towards veterinary and medical services, medical treatments received, education, women's reproductive history, drug abuse, people's perceptions of changes in environment and agriculture, demography, poverty and migration were collected via the questionnaires alongside information on livestock demographics and fertility. One of the main conclusions is that both medical and veterinary health care systems suffer from a number of shortcomings. The distance to appropriate treatment and care facilities is far and the necessary drugs are often unavailable. Also, both the knowledge and technology for diagnosing selected diseases is not in place. This study suggests that neurocysticercosis (NCC) plays an important role in this area due to the high number of seizures reported in people, in whom treatment for epilepsy was unsuccessful. Samples taken from a few pigs indicated the presence of Taenia solium, the causal agent of NCC. Furthermore, many of the TBIs are of zoonotic nature and further investigations must be made to begin to assess the burden of these diseases in humans and animals. Environmental changes such as degradation of the vegetation are likely to have an influence on the prevalence of studied diseases and this aspect is being investigated further in other studies. Due to the nature of a cross-sectional study, only limited conclusions can be drawn on the causal relationships of disease prevalence, but the social analysis conducted in this study confirmed the interactions of selected factors related to health and wealth unique for this study area.

Examining the Relationship Between Pet-Ownership & Human Physical and Psychological Wellbeing

Rehnfeldt, Hanna January 2020 (has links)
Despite copious research into the association between pet-ownership and human wellbeing in general, empirical data is contradictory and research focusing on the effect of pet-ownership across the lifespan is fundamentally lacking. This study provides analysis and discussion on the relationship between pet-ownership in childhood & human physical and psychological wellbeing in young adulthood. One hundred and ten people extending in age from of 18 to 25 responded to a questionnaire related to their demography, pet-ownership, and physical & psychological health. Finding(s) showed no main effect of pet-ownership on physical or psychological health. Furthermore, no significant relation was found between attachment or social support from a childhood pet and ensuing physical or psychological health. Comprehensively more research is required to veritably establish a link between pet-ownership & human physical and psychological wellbeing.

Who benefits and who loses? : Evaluating the impacts of community-based marine protected areas on ecosystem services and human wellbeing

Mahajan, Shauna January 2014 (has links)
Coral reef ecosystems are some of the most biologically diverse systems in the world, and provide a number of ecosystem services that humans depend on for their wellbeing. Marine protected areas (MPAs) are a social-ecological intervention that while conserving these ecosystems, also have significant impacts on the communities that depend on them for their wellbeing. Community-based MPAs are growing in popularity with the assumption that by putting communities at the forefront of their planning and management, more participation will occur, ensuring positive social and ecological impacts. This study, through mixed qualitative and quantitative methods, examines two community-based MPAs in coastal Kenya (called tengefus) to understand how each tengefu was incepted, and how resource users perceive the impacts of the tengefu on ecosystem services and human wellbeing. Participation in and donor support for the tengefu were found to influence how resource users perceived impacts. Individuals who were more engaged in the project or held some type of leadership position perceived more positive impacts on ecosystem services and human wellbeing compared to those not involved. In the two cases, tangible benefits (e.g. fisheries spillover and ecotourism) from the marine enclosure itself are too few to benefit the community as a whole. For tengefus to be social successes, more attention should be given to engaging all resource-dependent community members in their planning, implementation and management, and to understanding the multifaceted role of donor funding in supporting these initiatives.

The ecological economics of inter-basin water transfers: the case of the Lesotho Highlands Water Project

Matete, Mampiti Elizabeth 05 June 2006 (has links)
This study developed a general framework that can be applied to integrating environmental sustainability aspects into economic development planning in the case of exploiting water resources through inter-basin water transfers (IBWT). Using the Lesotho Highlands Water Project (LHWP) between Lesotho and South Africa (SA), the study used the multi-country ecological social accounting matrix (MC-ESAM) for Lesotho and SA to integrate ecological implications of the LHWP with the economic benefits of the project. The study further used the developed MC-ESAM multipliers to analyse the impact of lost ecological services downstream the LHWP dams in Lesotho on the wellbeing of households directly affected by the project in Lesotho and the general economies of Lesotho and SA. The MC-ESAM multipliers were also used to analyse different policy scenarios aimed at compensating affected households in Lesotho for ecological losses. The results revealed that while the LHWP has significant direct and indirect benefits in terms of social and economic development in Lesotho and SA, the project has serious unitended impacts on ecological resources and services, with resultant deleterious wellbeing implications for populations residing within the reaches of the LHWP rivers and downstream the LHWP dams in Lesotho. The results from the MC-ESAM multiplier analysis indicated that not only the income of populations directly affected by the project in Lesotho is likely to fall, but also that of other households and social groups, as well as the general economies of Lesotho. Also, because of economic dependence of Lesotho on SA in terms of imports, SA will also loose. The policy simulation results showed that compensating the ecological losses would greatly improve the welfare of directly affected populations and the rest of Lesotho economy. The empirical analysis and policy simulations results showed relatively small impacts in general, but were significant for groups of people directly affected by the project in Lesotho. The study demonstrated the importance of integrating ecological consequences into impact assessment of IBWT before such transfers can be implemented to ensure Pareto optimality and of considering economy-wide impacts and multi-sector, multi-country linkages associated with IBWT for a holistic impact assessment of IBWT. / Thesis (PhD (Agricultural Economics))--University of Pretoria, 2007. / Agricultural Economics, Extension and Rural Development / unrestricted

Nature experiences for human wellbeing and Human-Nature Connection

Maekawa, Ikumi, Pålsson, Kajsa January 2023 (has links)
Our contact with nature is decreasing in what has been referred to as the “extinction of experience”. Consequences of the loss of nature experiences are far-reaching and involve not only changes in health and wellbeing, but also changes emotions, attitudes, and behaviour towards nature. This research aims to fill a knowledge gap in understanding specific characteristics of nature experiences in relation to both a) generating human wellbeing, and b) improving Human-Nature Connection (HNC), defined as how people relate to nature. The aim is to increase our understanding of the characteristics of nature experiences that can achieve both of these positive outcomes. Furthermore, this research explores an organisational perspective through interviewing organisations that are currently incorporating or thinking to implement practices that include nature experiences. To address the main aim, an integrative literature review was conducted, and the results revealed that intentional contact, active engagement (specifically appreciative outdoor activities, cognitive engagement, cues, and direct earth contact), and biodiversity and wildness to be significant characteristics that positively impact human beings. Moreover, appreciative outdoor activities and cognitive engagement have been shown to be beneficial even when passive. In addition, there is some evidence that there is a link between HNC and wellbeing, which suggests that improving HNC would increase the wellbeing effects experienced by an individual during a nature experience. This knowledge is crucial for designing nature experiences that are able to more efficiently improve wellbeing, as well as improve HNC. Regarding the organisational perspective, a barrier that needs to be overcome is reaching an understanding of the benefits of such experiences, not only for the employees but for the business. One major opportunity identified is the hybrid working model, which allows employees to work remotely, and the possibility for the company to actively encourage its employees to experience nature.

Parkers potential för gynnande av humlor i urbana miljöer

Niva, Sanna January 2016 (has links)
Det här arbetet fokuserar på hur befintliga parker i centrala Gävle skulle kunna fylla en större funktion gällande gynnandet av humlor och annan biologisk mångfald och hur dessa parker skulle kunna omdesignas. Mina frågeställningar berör: befintliga parkers avsaknad av föda åt humlor, bristande möjligheter för dem att finna bo – och övervintringsplatser samt förslag på åtgärder för att motverka dessa problem. Resultatet av denna studie visar att parker kan fylla en större funktion gällande att gynna den biologiska mångfalden i urbana miljöer. Om inte bo– och övervintringsplatser och föda blir lätt åtkomligta för våra humlor riskerar vi att de minskar ännu mer i antal, och detta skulle kunna vara förödande för oss människor eftersom vi är helt beroende av dessa viktiga pollinatörer. Men med rätt kunskap och information till allmänhet och parkförvaltare går det att hjälpa humlor att skapa miljöer som hjälper humlor att kunna leva i urbana miljöer. Om vi med enkla medel inkluderar biologisk mångfald i stadens parker skulle vi kunna skapa gröna oaser där människor, djur och insekter kan trivas sida vid sida och även tillföra glädje för varandra. / This study is dealing with how existing parks in urban areas can fill a bigger role for bumblebees then they are today. My questions concern: lack of food for bumblebees in parks, lack of opportunities to find places to live and to hibernate and actions how to mitigate this. The results of this study show that existing parks can have a bigger positive impact on the biodiversity in urban areas. If bumblebees can’t find places to live or hibernate or find food, the risk is then that their populations will continue to decline which will have a strongly negative effect on us humans because we are depending on pollinators. With the right knowledge and measures we can make it easier for bumblebees to live in urban areas. To facilitate for biodiversity in the planning of parks means that we will create oases which both humans, birds and insects can benefit from.

Transitional landscapes : examining landscape fragmentation within peri urban green spaces and its impacts upon human wellbeing

le Brasseur, Richard January 2018 (has links)
Transitional land uses produced through urbanisation continue to change the landscape and fragment ecological structures including green spaces across Europe (Nilsson et al., 2013). Green spaces offer significant benefits to humans, contributing to wellbeing and life satisfaction (Taylor, 2002). The understanding of how these unique green spaces spaces function and provide benefits to humans, and how landscape change in peri-urban contexts affects their performance, is important. The scope of this research is to contribute to an understanding of landscape fragmentation within some of Europe's polycentric urban regions, their peri-urban green spaces, and the associated impacts upon human quality of life. Two urban regional case studies, Paisley near Glasgow, Scotland, and Vantaa, near Helsinki, Finland were analysed and compared. The results indicate that humans interacting with more physically or ecologically fragmented peri-urban green spaces have higher self-reported life satisfaction levels. Though no statistically significant characteristics were apparent between life satisfaction and fragmented green space characteristics, this research was able to identify those specific structural attributes and physical characteristics of interstitial peri-urban green spaces within a polycentric region in a fragmented state that contribute to the physical, social, and psychological aspects of human wellbeing. The statistically significant eco-spatial characteristics of polycentric peri-urban interstitial green spaces that are reported to impact human wellbeing are the size, proximity, maintenance and management, and the level of greenness within its vegetation composition and setting. Overall, a spatially diverse, fragmented, peri-urban landscape whose green spaces are extensively sized, naturalistically shaped with horizontal vegetation and normal sized edges, most often parks or woodlands or forests which are integrated and physically connected to another green space which is moderately clean and somewhat safe as well as being located close to or adjacent to a heavy-trafficked road provide the most human wellbeing benefits.

Prospects of limiting the right to reproductive health in South Africa : a human wellbeing and socio-economic view

Matsheta, R. M. January 2019 (has links)
Thesis (M. Law. (Development and Management)) --University of Limpopo, 2019 / Like many other countries, South Africa has its own socio-economic challenges. For the past two decades, the country has been experiencing rapid population growth, yet in the same period, there has been a pervasive decline in social and economic stability, and in the end, stagnant human wellbeing. This has been as a result of diminishing access to basic services such as health care, quality housing, quality education and safe clean drinking water. Among other factors, unregulated and rapid population growth contribute to these socio-economic challenges. This study seeks to illustrate that overpopulation undermines and threatens social development, societal stability and survival of humanity. Therefore, the examines the possibility of enacting a legislation or policy that will regulate or limit procreation or the right to give birth. It also reflects on the Chinese experience to obtain some lessons from China’s One-Child Policy. It is submitted that South Africa must draft its own policy or legislation that will regulate population growth with the primary objective of aligning population with available state resources. Keywords: overpopulation, right to reproductive health, socio-economic rights, human wellbeing, social transformation.

Spatial analyses of people's experiences in urban landscapes

Samuelsson, Karl January 2019 (has links)
Limiting cities’ negative impact for global sustainability suggests compact city development. However, extensive and accessible urban nature is important for urban dwellers’ wellbeing. Aligning efforts to make cities locally and globally sustainable means resolving this conflict. This thesis applies spatial analysis of urban dwellers’ regularly occurring experiences, as these are important wellbeing indicators, looking specifically at Stockholm, Sweden. The aim is to contribute to a nuanced understanding of urban environments’ influence on urban dwellers’ experiences. Paper I investigates how accessibility to various environment features impact the probability that people have positive or negative experiences. Paper II applies resilience principles to investigate what experiences exist together in neighbourhoods. The environment have considerable influence on people’s experiences. Some common indicators in urban planning display weak relationships with experiential outcome, while other less common ones have larger effects. Neighbourhood compositions of experiences display consistent patterns, both spatially across Stockholm and with respect to resilience principles. Many neighbourhoods harbour diverse positive experiences, while a few are dominated by negative ones. The results suggest that human-environment relations should be given more consideration in urban discourse and urban planning. A relational approach could improve urban dweller’s experiences, and positively influence their wellbeing. For urban planning to be able to handle the complexity of such an approach, I suggest that resilience principles can be heuristics for an urban development that does not compromise people’s experiences. The methodological framework developed here can be applied in other cities, as it can identify specific places for transformation, but also increase knowledge of the interplay between urban environments and people’s experiences across different contexts. / För att begränsa städers negativa påverkan på global hållbarhet förordas ofta kompakta stadsmiljöer. För att säkra stadsbors välbefinnande krävs emellertid stora och tillgängliga naturområden. Denna konflikt måste lösas för att nå en stadsutveckling som bidrar till både lokal och global hållbarhet. Denna avhandling består av två studier av Stockholm som tillämpar rumslig analys av människors upplevelser, då dessa är viktiga indikatorer för välbefinnande. Den undersöker hur tillgänglighet till olika miljöfaktorer är relaterade till positiva och negativa upplevelser. Vidare tillämpar den resiliensprinciper för att undersöka vilka upplevelser som samexisterar på områdesskala. Stadsmiljön har betydande påverkan på människors upplevelser. Vissa vanliga indikatorer inom stadsplanering visar svaga samband med upplevelser, medan andra mindre vanliga har större effekter. Sammansättningar av upplevelser på områdesskala uppvisar genomgående mönster, både rumsligt och i förhållande till resiliensprinciper. Många områden innehåller en mångfald av positiva upplevelser, medan ett fåtal domineras av negativa upplevelser. Resultaten visar att relationer mellan människa och miljö bör ta en mer central plats i stadsplaneringen, då detta erbjuder möjligheter att förbättra stadsbors upplevelser. Resiliensprinciper kan fungera som tumregler inom stadsplaneringen för en stadsutveckling som inte äventyrar människors upplevelser. Metoden som utvecklats här kan appliceras i andra städer, då den kan identifiera specifika platser för omvandling, men också leda till djupare förståelse för samspelet mellan stadsmiljöer och människors upplevelser i olika sammanhang.

<b>Development of a Variable Dilution Olfaction Chamber Coupled with a Proton Transfer Reaction Mass Spectrometer for Evaluation of Human Response to Indoor Emissions from Scented Volatile Chemical Products</b>

Jordan N Cross (16700061) 02 August 2023 (has links)
<p>This study is focused on the design, production, and operation of a controlled environmental olfaction chamber to evaluate human physiological and emotional response to volatile chemical emissions (VCPs) from scented household products in addition to careful characterization of the volatile organic compounds (VOCs) present in these product emissions. Utilizing proton transfer reaction time-of-flight mass spectrometry, the chamber can collect VCP emissions and identify VOCs present to complete an accurate chemical profile of household and common product emissions not previously known. This instrument is one of the first of its kind and will serve as a key element in understanding the relationship between human physical and cognitive health and the built environment.</p>
