Perceptions of traditional healers regarding ethnobotanical importance and conservation status of indigenous medicinal plants of Thulamela, LimpopoNefhere, Khamusi Victor 03 1900 (has links)
Medicinal plants of Thulamela municipality are experiencing challenges due to human activities, resulting in some of the medicinal plants becoming difficult to find, declining, endangered or even extinct. Unsustainable harvesting is threatening the survival of certain medicinal plant species used as a source of primary healthcare in the area.
This study investigates aspects related to traditional healers' perceptions with regard to collection, ethnobotanical importance and conservation status of indigenous medicinal plants used by traditional healers around Thulamela municipality. Information on medicinal plants was gathered by means of semi-structured interviews, field walks, personal observation and a literature review.
A total of 90 medicinal plant species, which belong to 47 families, from a total of 82 genera commonly used by traditional healers to treat different ailments, were recorded.
About 87% of traditional healers indicated that some medicinal plants are difficult to find; only 13% of healers did not experience difficulties in finding some medicinal plants. / Environmental Sciences / M. Sc. (Ornamental Horticulture)

"Back to the land and all its beauty" : managing cultural resources, natural resources, and wilderness on North Manitou Island, Sleeping Bear Dunes National Lakeshore, MichiganFredericks, Katelyn V. January 2014 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / This thesis focuses on the history of human impact on North Manitou Island, Michigan, the management of natural and cultural resources on the island by Sleeping Bear Dunes National Lakeshore, and the often conflicting beliefs and attitudes about wilderness and cultural resources that influenced (and continue to influence) management of the island by Sleeping Bear’s administrators.

Anthropocentric impacts on the ecology and biodiversity of the Natalspruit watercourse and its associated wetlandsKruger-Franck, Elmarie 07 1900 (has links)
Information regarding the ecological wellbeing of the Natalspruit and its adjoining wetlands is
essential if the river is being managed using sound ecological management principles. Despite
this, little is known about this river, with little documentation at the regional or municipal level.
This study partially addresses this knowledge gap by evaluating the impacts of human activity
on a section of the Natalspruit and its adjoining wetlands. It reports on pollution concentrations
found at selected sample sites and compares the results to Rand Water data and the National
Standards and Guidelines of South Africa for physicochemical parameters and contaminated
soils. Water samples were collected at five chosen sample sites during May and July 2018. Soil
samples were taken during July 2018. The study found that water at all five sample sites is not
suitable for drinking, the health of livestock and recreational use due to the present and high
Total Coliform levels (ranging from 450 CFU/100ml to 100 000 CFU/100ml), as well as
Turbidity, Total Hardness, TDS, Mg, NO2, SO4, and BOD which also exceeded the guidelines.
Only site SS1 (May) exceeded the CaCO3 concentrations regarding livestock health. No
guidelines were available for DO levels on the health of livestock. Cl levels in the Natalspruit
was suitable for drinking. PO4 concentration at all the sites were all within the guidelines of
acceptable levels for aquatic ecosystems. In terms of heavy metals, Cr levels significantly
exceeded the guidelines at all five sample sites with the exception of ecosystem health. This is
of great concern due to the toxicity of Cr. Cu concentrations exceeded the guidelines for both
all land-uses protective of water resources and ecosystem health, at SS1, SS2, SS3 and SS5. Ni
concentrations exceeded the guidelines for all land-uses protective of the water resources at
SS5. Pb and Zn concentrations exceeded the guidelines for the land-uses protective of the water
resources at all the sites with the exception of SS4 for Pb and SS2 and SS4. SS1 and SS5
reported Zn concentrations higher than the guideline for the protection of ecosystem health.
SASS 5, PES and EIS assessments indicated moderate to severe modifications of the river.
Thus, mining, industrial activities, surface runoff from densely populated informal settlements and wastewater treatment plants have negatively impacted upon the river. Decades of
environmental neglect and effluent discharge have degraded the ecosystem, thus necessitating
rehabilitation. However, as the study was limited in both time and scope, so additional research
should be undertaken. / Environmental Sciences / M. Sc. (Environmental Management)

Wattle we do? alien eradication and the 'ecology of fear' on the fringes of a world heritage site, South AfricaMerron, James Lawrence January 2010 (has links)
In their article ―Naturing the Nation: Aliens, the Apocalypse and the Post Colonial State (2001) Jean and John Comaroff look at ―the contemporary predicament of South Africa through the prism of environmental catastrophe. Through it they reveal the context in which alien plants have become an urgent affair of the state. Following their lead, I show how alien plants (particularly Australian wattle) continue to provide grounds for new social and political aspirations in South Africa, though in a different setting. With reference to a group of private landowners on the fringe of a World Heritage Site -- the Baviaanskloof Mega-Reserve, Eastern Cape, South Africa -- I show how an increasingly apocalyptic and xenophobic environmental agenda has influenced local activists seeking to address social and ecological issues in tandem with alien-eradication. These local activists adhere to a particular brand of environmentalism which Milton (1993) argues can be considered a social, cultural and religious phenomenon. The subjects of my main empirical investigation offer practical ways of achieving a transformational end through a new ritual activity in relation to a spread and exchange of environmental ideas and practices on a world-wide scale. On the ground this group practices ecosocietal restoration through which they aspire to mend the bond between people and the land in a spiritual and moral sense, bolstering intrinsic incentives for environmental stewardship and achieving ―cultural reconciliation in an attempt to reimagine what South Africa could be.

Obchodování s lidmi: role EU v přístupech k problému v ČR a Belgii / Human trafficking: the role of the EU and the approaches to the problem in Czech Republic and in BelgiumHaniaková, Tereza January 2020 (has links)
This master thesis aims to unveil and examine the interplay between different actors in the fight against human trafficking. These are: the European Union, the Czech Republic and Belgium. A content (text) analysis of the primary sources gives the answers on how those actors work with the definition of human trafficking and to what extent the two member states implemented the EU Directive 2011/36/EU and other documents. In addition to conducting the content (text) analysis, creating a literature review and researching on different discourses linked to this phenomenon, this thesis include two semi-structured interviews with the representatives of the Czech Republic and Belgium. Those offer deeper insight into how those states form this fight in practice. They unveiled different aspects in their own approaches but also aspects that make their approach unique. This thesis examines also how the new strategy - the most important document framing the fight against human trafficking and the country's priorities - is adopted and what generally will those strategies include from the year 2020.
