Community-based natural resource management: The case of Community Forest Management Areas in Pete, Zanzibar

Dabo, Dina January 2017 (has links)
The shift from centralised conservation to Community-Based Natural Resource Management (CBNRM) was the highlight of the conservation discourse across the world during the late 1980s and early 1990s. CBNRM efforts were believed to have the potential of successfully merging biodiversity conservation simultaneously with local development efforts. However, the increasing critiques against the applicability of CBNRM interventions in different contexts is threatening the viability of the approach. Extant literature on CBNRM interventions focuses on the theoretical aspects of such efforts at the expense of the practical and context specific elements. This thesis intends to fill such a gap in literature by focusing on the practical and contextual elements of an example of this approach in Zanzibar. In an attempt to conserve the isles' natural forests, Zanzibar has adopted Community-Forest Management Areas (CoFMAs) bordering its natural forests. In this study, focus is placed on Pete's CoFMA, a village bordering the isles' last remaining natural forests- Jozani-Chwaka Bay National Park (JCBNP). Pete provides an ideal site due to the conflict that exists between residents and the CoFMA intervention. By using the political ecological framework, this study is able to examine the political, social, historical and economic elements that play a significant role in the practice of CBNRM efforts. Narratives from residents are relied on to elucidate on such elements in relation to the existence of the CoFMA in Pete Village. Narratives gathered through interviews and participant observation concluded that while CoFMAs have been set up with the optimistic goal of conserving the forest and providing development to community members; in practice, the conservation intervention has proved otherwise. In spite of the achievement of some developmental goals, the overall findings indicate that the CoFMA has failed to protect the forests and its natural resources from degradation. At the same time, community members are facing difficulties to live a sustainable life.

A Decision Theory Approach to a Resource Management System in Corn Production

Anderson, James L. 01 May 1976 (has links)
The major purpose of this study is to make additional information available to the farm manager through the use of decision theory . This will enable him to improve the decision-making process relating to corn production. The goal is to use the resources at his disposal more efficiently and profitably. This study is primarily concerned with factors that influence planting date and corn variety selection. Within the framework of decision theory analysis , prior and posterior probabilities are employed to calculate the losses that may occur to corn crops in the Cache Valley area of Utah because of harmful spring frosts under optional corn varieties. The alternative of replanting is also added to the model. A brief discussion is included regard ing the impact of water shortage on planting date and corn variety selection. A discussion of factors influencing harvesting decisions is included. The "seventy growing degree day" method is employed as a criterion for planting date select ion. The planting dates a r e matched with four different season length Utah hybrid corn varieties to formulate the courses of action available to the farm manager. The states of nature are the degrees of damage that would occur due to various frost intensities. The decision theory approach of this study identifies the short season variety as the optimal corn crop for Cache Valley, unless planting can be done during the first week in May. This study indicates that planting a shorter season vadety than most Cache Valley farmers have been using in the past would be profitable . Replanting after a frost is found to be unprofitable in marginal cases , but necessary in the case of a killing frost of sufficient duration. The problem of a short water supply adds a constraint as to what varieties can be planted where the time required to reach the third stage of growth is most critical in obtaining potential yields . Finally , it was found that the risk of increased precipitation interfering with harvesting operations becomes almost a certainty if attempts to lengthen the season pushes the harvest too far in to October .

Defining Efficient Water Resource Management in the Weber Drainage Basin, Utah

Wilde, Keith D. 01 May 1976 (has links)
The Weber Basin Water Conservancy District is a state institution, but its primary function is collecting money for the U.S. Bureau of Reclamation, to pay for the Weber Basin Project. Ditferent classes of water users pay markedly different fees for identical Project services. More than half of the water developed by the Project is not used consumptively, yet supply facilities continue to be built in the Basin because they are less expensive to their owners than prices charged for the underused capacity of the Project. Paradoxically, some Basin residents are bitterly resentful of both the District and the Bureau, claiming that water rights formerly their own have, by means of the Project, been stolen. That is, both the enemies and the proponents of the Project adhere to the Western orthodoxy that water i.s scarce and drought imminent. The principal difficulty of this investigation lay in identifying the nature of the problem, for the situation seemed full of contradictions. Consequently, the primary contribution of the dissertation is an explanation of Basin circumstances that accounts for arresting observations without inconsistency or contradiction. The most important hypotheses are, therefore, empirical, or historical and institutional. Economics, according to Richard T. Elya and Frank H. Knight, is a set of principles concerning what ought to be, not empirical description of what ~· Consistent with that perspective, once the nature of the problem is clear, application of economic principles is a prescriptive judgment of how the problem may be resolved. The most important empirical hypotheses are as follows: Water is not scarce in the Weber Basin; neither are storage and conveyance facilities. All are abundant, even redunda nt. Nevertheless, in combination with certain institutional arrangements and a sustained propaganda campaign, this very abundance contributes to persistence of the attitude that water is scarce. Redundant facilities the reby encourage even more unneeded development. What appears on first examination to be a case of misallocated water resources by discriminatory prices, turns out to be a problem of distributing the burden of paying for excessive, unwanted public works. Water itself is a free good in the Basin. Actual distribution of the repayment burden is partly ideological and partly pragmatic; partly a political choice and partly a bureaucratic decision; partly a manifestation of agrarian policy and partly what the traffic will bear. If water is free, it is not an economic good, and not a subject for economic analysis . The Basin has an ample water supply, but water may nevertheless be locally and periodically scarce. The water problem is therefore one of conveyance and timing. Control of timing requires storage. Conveyance requires energy, as well as aqueducts. In the Weber Basin, conveyance energy may be either the controlled flow of falling (mountain) water, or electrically powered pumps tapping abundant groundwater reservoirs. The water development problem is, therefore, an issue of alternative capital facilities for the control and delivery of water (itself abundant). Efficient resource allocation in water development is consequently relevant at the !.!!vestment level; it is not a matter of pricing water. In this case, the major investment decisions have already been implemented, and the problem is one of evaluating distribution of the repayment burden. The relevant economics literature is principles of equitable taxation, and of public utilities' pricing. Application to the Basin situation produces a conclusion that present arrangements are as equitable as could be devised. Further redundant investment (inefficient use of resources), however, could be avoided if the State Engineer's Office took a harder line on requests to drill new wells. The information provided in this work could be the basis for making such a program popularly acceptable.

Living organisational values in a multi-cultural environment : a South African case study

Cloete, Annemarie 30 September 2013 (has links)
Organisational values consist of enduring and indispensable tenets which underpin organisational culture and form the foundation for an organisation’s purpose and goals. It should represent a unique set of collectively shared values, which silently gives direction to the multitude of decisions to be made on a daily basis within the organisational domain. Unfortunately, companies seem to place an overt focus on articulating and promulgating their values as opposed to embedding it in the hearts and minds of their employees, who ultimately have to live the values. The challenge therefore still remains for organisations to not only articulate their values, but rather focus on inculcating and, in actuality, living these values, thereby making them a business ‘weapon’ - a powerful source to be reckoned with.

Correlates of Adjustment: A Study of Expatriate Managers in an Emerging Country

Yavas, Ugur, Bodur, Muzaffer 01 April 1999 (has links)
To minimize adverse consequences associated with expatriation, multinational companies need to identify the factors which facilitate (or impede) expatriate managers adjustment to a new environment. In this study, on the basis of their adjustment to four diverse aspects of life and work in Turkey, a sample of 78 expatriate managers were dichotomized into high and low adjustment groups. The two groups were then compared in terms of selected company and individual-related characteristics, previous international experience and the types of training received prior to and during the assignment. The article discusses these results and proffers strategies to facilitate expatriates adjustment to the Turkish environment.
