Loss of biodiversity : problems of its legal control in Ethiopia

Damtie, Mellese January 2014 (has links)
This thesis is conducted on the premise that the existing legal, policy and governance frameworks are insufficient to protect biodiversity from the alarming loss it is facing now. It argues that these frameworks are crafted to conform to the dominant paradigm of anthropocentrism; a paradigm which believes that humans are the pinnacle of creation and everything on Earth, including the Earth itself destined to satisfy only the interests of humanity without having their own purpose. By showing how anthropocentric worldview conceived, developed and spread, and how this worldview managed to influence societal collective consciousness to govern the relationship established between humans and the nonhuman nature, the thesis argues that loss of biodiversity not a problem in itself. Rather it is a symptom of the underlying problem rooted in human thinking, guided by anthropocentric worldview. Anthropocentrism has become a powerful paradigm that succeeded in permeating into dominant religions, knowledge base and legal systems of countries of the world, including Ethiopia. The thesis contends that law, as mirror of dominant paradigms and perceptions, reflects the values of these paradigms, at international as well as national levels putting protection of biodiversity within the interpretations of these paradigms. It argues that the human treatment of the natural environment is on a scale of violence which puts the survival of humans and that of the environment at a precarious condition. Based on evidence from the review of evolutionary science and the Holy Scriptures, the thesis argues that humans are deeply connected to and dependent on the Earth systems and are responsible to maintain these systems which are functioning in a holistic manner to support all life on Earth. Promoting the proposition of Thomas Berry that the Earth is a community of subjects not a collection of objects, it contends that biodiversity has intrinsic value in addition to instrumental value, deserving ethical extension. Drawing on these concepts, the thesis suggests, by adopting a reformist approach, a shift from the reductionist notion of anthropocentrism to ecocentrism via the new philosophy called Earth jurisprudence. Earth jurisprudence is believed to correct and heal the conflicting relationship that humans established with the nonhuman nature, with the view to reconciling the present legal, policy and governance systems which have been dominated by anthropocentric perspectives. Through the vehicle of Earth jurisprudence, it is hoped that humans assume a stewardship responsibility for the mutual benefits of humans and nonhuman nature. The thesis finally deals with a case study conducted in Sheka zone in the Southwest Ethiopia. The case study is done with the purpose of exploring the TEG systems of indigenous/local communities which are believed to conform to the tenets of the Earth jurisprudence, the philosophy of law which is chosen by this work to guide the protection of biodiversity. The case study came out with findings that the Sheka TEG systems are good examples of customary practices that provide better protection for biodiversity. Exemplary lessons can be drawn from the Sheka TEG systems to amend the dominant legal, policy and governance regimes.

The challenges of land law reform, smallholder agricultural productivity and poverty in Ethiopia

Lemma, Solomon Fikre January 2015 (has links)
Ethiopia has experimented with land law reforms linked to agriculture-led national development strategies that Emperor Haile Sellassie I, Derg, and EPRDF introduced since Emperor Menelik II enacted modern Ethiopia’s first reform intended for development in 1908. Nonetheless, the country’s smallholder productivity averaged 1.0 ton/hectare and its poverty ranked 174th in the UNDP Human Development Index in 2011. This thesis examines whether and how land law reform can be used to help raise smallholder productivity and tackle poverty in Ethiopia notwithstanding the challenges of legal pluralism. By drawing upon evidence from law and development research and experience and analysing it in the Ethiopian context, the thesis argues that reform can help raise smallholder productivity, but only by recognising legal pluralism and changing the land tenure system’s formal state or non-formal customary land policies, laws, and institutions which constrain the provision and implementation of productivity-raising smallholder land rights that enhance tenure security, facilitate the transfer of rights over land, and authorise the collateralisation of land rights; and tackle poverty by thereby increasing food supplies, raising incomes, and improving health, education, and other necessities for the country’s predominantly rural population. Specifically, the thesis explores the possibility of using reform to adopt a hybrid state-private-customary land policy that combines the advantages of state land ownership policy that the government enforces, private ownership that critics favour, and non-formal arrangements that society uses. It then highlights how within the framework of this hybrid policy reform may help issue land laws boosting the provision of land rights that enhance tenure security by specifying definition of state, private, and communal landholdings, certification of lifelong usufructuary landholding, stricter eviction and confiscation procedures, and clearer expropriation and compensation mechanisms; that facilitate transfer by easing lease, donation, and succession restrictions; and that authorise collateralisation conditionally. Finally, it demonstrates how reform may help establish land institutions that improve implementation by incorporating non-formal arrangements, establishing a federal executive institution, clarifying the mandates of regional institutions, and assigning the judiciary greater dispute resolution role.

State policy and law in relation to land alienation in Ethiopia

Srur, Muradu A. January 2014 (has links)
The thesis examines the nature and mechanisms of land alienation in the context of Ethiopia's history of land relations and the role of national and global actors. In consideration of these themes, the study has adopted a contextual analysis of law and policy. Data from fieldwork has informed the core themes. It has also involved a combination of doctrinal legal research and documentary policy research augmented by quantitative data. The research considers issues of land alienation in the situation where the main relevant perspectives argue for the abolition of the people's ownership of land approach embodied in the country's 1995 Constitution and its replacement by private ownership of land (privatization perspective) or for its modification to allow alienation of land use rights (revisionist perspective) or for its change into village ownership of land with a possibility of market transfer of land use rights (associative ownership perspective). In addition to their promotion of one or another form of land alienation, the above three perspectives focus on consideration of ways to break the bureaucratic power of the State over land. This study contends that a focus on these issues has prevented the perspectives from fully identifying and thus explaining features of the ongoing land alienation in Ethiopia including the position of international institutions. This thesis therefore claims that there is an underlying shift towards marketable property in land in favor of actors who are assumed to be 'better land improvers. This is happening in a dual context of significant land poverty and economic growth.' Land alienation is being manifested in rural land expropriation laws, administrative and judicial endorsement of kontract, absence of recognition of communal lands and transfer by the State of the communal rural lands to large-scale farmers through the deployment of discourses such as 'empty land' and the 'tragedy of the commons.' This gravitation clashes with the people's ownership of land approach that provides for agricultural land for peasants and pastoralists, security of their landholdings and a ban on land alienation. The tilt has resulted in another tension between federal and regional governments where the Centre claims that efficiency demands that it handle land transfers to developers whereas the regions assert their constitutional power over land. Similarly, global institutions are involved in a contradiction because they prescribe land rights to the poor as a strategy to reduce poverty in Ethiopia and at the same time they encourage large-scale land grants in accordance with `principles of responsible agricultural investment.' The thesis proposes an affirmation of the constitutional principles concerning land with a proper form of constitutionality.

Introducing plea bargaining in Ethiopia : concerns and prospects

Meheretu, Alemu January 2014 (has links)
The thesis is about a contextual and prospective analysis of the Ethiopian variant of plea bargaining focusing on the major components of legal culture, legal structure and principles of criminal law and procedure. To this end, it makes use of a thorough analysis of policy and reform documents, laws, as well as comparative literature, interviews and questionnaires. The thesis argues that the Ethiopian variant of plea bargaining is less desirable and feasible. It hardly fits into the Ethiopian legal system for it is constrained by inherent due process concerns in an exacerbated fashion as well as structural/institutional and cultural limitations. Here three subarguments emerge: First, plea bargaining which inherently relates less to evidence and circumvents fundamental principles of criminal law and procedure, aimed at ensuring the integrity of the process, is likely to yield , inter alia, inaccurate outcomes- the innocence problem. With a less developed legal structure (weak defence in particular) and weak legal culture/rule of law, the problem would be exceptionally formidable in Ethiopia. Second, huge structural and functional limitations of legal institutions- the police, the prosecution, the judiciary, and the defence/legal aid, mean plea bargaining would not fare well. Third, plea bargaining tends to be incompatible with the prevailing legal culture. In America and Western Europe, it is often characterized by problems of fairness and outcome inaccuracy. On the face of weak legal culture/rule of law, it remains to be more so in Ethiopia. While plea bargaining may solve problems of delay and enhance efficiency in many jurisdictions, it is not a universal prescription, though. With jurisdictions like Ethiopia whose legal institutions and legal culture are less developed; whose trial appears to be simple, inexpensive, less utilized and correlates very loosely as an underlying cause of delay, plea bargaining is less likely to offer the desired efficiency gains even at all costs. Conversely, it would be more of a liability than an asset at least in three senses: it is likely to yield inaccurate outcomes- wrongful convictions in an aggravated fashion; put defendant`s rights at greater risk, and leave a room for abuses and corruptions.

State law and the (post)colony : a critical analysis through group conflicts in Turkana

Baraza, Masha January 2014 (has links)
In documented incidents alone, between January 2006 and December 2009, 900 people were killed in 534 incidents of group conflict in Turkana. On the basis of this apparent lawlessness, the central research question queries whether the apparent inability of the state law and its institutions to manage group conflicts in Turkana districts denotes a crisis of application or a crisis of substance. Is the problem merely the extension of structures of state law such as courts, prosecutors, security agents, prisons and advocates to Turkana or does the crisis speak to a more fundamental challenge. The research argues the latter, that the relationship between state law and group conflicts in Turkana demands an interrogation of the conceptual and institutional dimensions of modern state law. The thesis interrogates how state law is incorporated; an apparatus of power through which certain regulative rationalities come to reframe the terrain upon which people in Turkana live and define their lives. In order to move state law in a radically improving direction, the research argues for a reorientation of rationalities and legality. The reorientation is advanced through two corresponding techniques that allude to the structural and perspectival elements of state law. Fashioned from amongst the unfinished representations of modernity and the initial task of conceiving a (post)colonial tension between regulation and emancipation, the first task involves building on those progressive aspects of state law that enhance its political legitimacy. The second requires the adoption of a transgressive mode of thinking described as 'knowledge-as-emancipation'. On the basis of these two prescriptions, state law can develop a more purposeful and emancipatory purpose within the conflict context of Turkana in particular, and Kenya in general.

Satellite investigations of ice-ocean interactions in the Amundsen Sea sector of West Antarctica

McMillan, Malcolm John January 2012 (has links)
This thesis analyses satellite-based radar data to improve our understanding of the interactions between the Antarctic Ice Sheet and the ocean in the Amundsen Sea Sector of West Antarctica. Over the last two decades, the European Remote Sensing (ERS) Satellites have provided extensive observations of the marine and cryospheric environments of this region. Here I use this data record to develop new datasets and methods for studying the nature and drivers of ongoing change in this sector. Firstly, I develop a new bathymetric map of the Amundsen Sea, which serves to provide improved boundary conditions for models of (1) ocean heat transfer to the ice sheet margin, and (2) past ice sheet behaviour and extent. This new map augments sparse ship-based depth soundings with dense gravity data acquired from ERS altimetry and achieves an RMS depth accuracy of 120 meters. An evaluation of this technique indicates that the inclusion of gravity data improves the depth accuracy by up to 17 % and reveals glaciologically-important features in regions devoid of ship surveys. Secondly, I use ERS synthetic aperture radar observations of the tidal motion of ice shelves to assess the accuracy of tide models in the Amundsen Sea. Tide models contribute to simulations of ocean circulation and are used to remove unwanted signals from estimates of ice shelf flow velocities. The quality of tide models directly affects the accuracy of such estimates yet, due to a lack of in situ records, tide model accuracy in this region is poorly constrained. Here I use two methods to determine that tide model accuracy in the Amundsen Sea is of the order of 10 cm. Finally, I develop a method to map 2-d ice shelf flow velocity from stacked conventional and multiple aperture radar interferograms. Estimates of ice shelf flow provide detail of catchment stability, and the processes driving glaciological change in the Amundsen Sea. However, velocity estimates can be contaminated by ocean tide and atmospheric pressure signals. I minimise these signals by stacking interferograms, a process which synthesises a longer observation period, and enhances long-period (flow) displacement signals, relative to rapidly-varying (tide and atmospheric pressure) ones. This avoids the reliance upon model predictions of tide and atmospheric pressure, which can be uncertain in remote regions. Ice loss from Amundsen Sea glaciers forms the largest component of Antarctica’s total contribution to sea level, yet because present models cannot adequately characterise the processes driving this system, future glacier evolution is uncertain. Observations and models implicate the ocean as the driver of glaciological change in this region and have focussed attention on improving our understanding of the nature of ice-ocean interactions in the Amundsen Sea. This thesis contributes datasets and methods that will aid historical reconstructions, current monitoring and future modelling of these processes.

The Martian Near Surface Environment: Analysis of Antarctic Soils and Laboratory Experiments on Putative Martian Organics

Archer, Paul Douglas January 2010 (has links)
Understanding the physical properties as well as the potential for organic material in the Martian near-surface environment can give us a glimpse into the history of the site with regards to water, soil formation processes, as well as the conditions necessary for life. This work is done to support the interpretation of data from the Phoenix Mars Lander as well as other past and future landed missions. The Antarctic Dry Valleys are a hyper-arid cold polar desert that is the most Mars-like place on Earth. Soils from two different soil and climate regimes are analyzed to determine their physical properties such as mineralogy, particle size, shape, color, and specific surface area. These data are used to describe the sample locations in Antarctica and infer properties of Martian soils by comparison to Antarctic sites. I find that the particle size distribution can be used to determine the water history of the site and that the behavior of soluble species in the soil can also be used to trace the movement of water through the soil and could be instructive in understanding how soil organic material is processed by the environment. Continuing with the theme of soil organic matter, we revisit the Viking conclusions with regards to organics on Mars and look at the Phoenix data on the same subject. First, we assume that Mars receives organic material from meteoritic infall. These organics will be processed by chemical oxidants as well as UV light down to 200 nm. Chemical oxidation is predicted to produce molecules such as mellitic acid, which could preserve up to 10% of the original organic mass. Using mellitic acid and other similar organic molecules, we irradiate these molecules with Mars-like ultraviolet light, analyzing the gases that come off as irradiation takes place. We find that organic molecules can survive Mars-like UV conditions as layers of UV-resistant organics build up, shielding the remaining organic material. Additionally, the gas products of irradiation depend on the composition of the original organic molecule, implying that even irradiated molecules will carry some information about the composition of the original molecule. Finally, we take this irradiated organic/soil stimulant mixture and analyze it via pyrolysis, similar to the Viking GC/MS and TEGA instruments that are the only instruments operated on Mars capable of detecting organics. We find that the pyrolysis of mellitic acid (and other similar) molecules primarily produces inorganic fragments but that the reduced carbon fragments released depend on the composition of the original organic. However, the introduction of perchlorate, discovered on Mars by the Phoenix Lander, complicates the issue by creating the conditions for molecular oxidation. The high-oxygen content and high pyrolysis temperatures lead to organic combustion during thermal analysis, meaning that, regardless of the initial composition, most soil organics will be oxidized to CO₂ during the detection process. By assuming that organic material was oxidized to CO₂ in the Phoenix and Viking samples. We show that this assumption gives organic concentrations consistent with meteoritic accumulation rates. This finding reopens the possibility for organic molecules in the near-surface environment at the Viking and Phoenix landing sites.

Telecommunications law and regulation in Nigeria : a study of universal service provision

Opata, Chukwudiebube Bede Abraham January 2010 (has links)
This thesis undertakes an analysis of the law pertaining to the regulation of telecommunications in Nigeria generally and more specifically with regards to the extension of access to telecommunications services to unserved and underserved persons and areas in Nigeria. The study is situated in the context of privatisation and liberalisation reform of the Nigerian telecommunications sector. It addresses the question of how to extend access to telecommunications services in Nigeria to unserved and underserved persons and areas. This question is researched by focusing on the sector regulator the Nigerian Communications Commission and analysing the mechanisms, ranging from licensing to interconnection to universal service provision and the National Rural Telecommunication Programme, that have been deployed in the past to achieve this objective to ascertain how these may be improved to ensure that as many persons and areas as possible have access to telecommunications services. The issue of securing the accountability of the regulator responsible for the deployment of these access extension mechanisms is also addressed. The research identifies the main international influences on the development of the Nigerian regulatory framework and shows the country’s ability to borrow from a number of sources while adapting and refining the borrowed rules to solve Nigerian problems. The thesis makes a contribution to knowledge in at least three material ways. It is, to the best of my knowledge, the first work on the legal framework for the regulation of telecommunications in Nigeria after the enactment of the Communications Act 2003. Secondly, it is also the first work that I am aware of which analyses issues of access to telecommunications services using a variety of regulatory mechanism as opposed to focusing on universal access and universal service alone. Finally it presents a positive illustration of a successful outcome of globalisation of rules, specifically the transposition or transplantation of specific legal rules in the economic context of a developing African country.
