Food crisis, administrative response and public action : some general implications from the Kalahandi issue

Currie, Bob January 1993 (has links)
Kalahandi district in Western Orissa has received extensive media attention in recent years in connection with reports of starvation deaths, child sales and Government neglect. This thesis attempts to identify the roots of hunger in Kalahandi and strategies implemented by people in the district to cope with this problem. It also analyses the performance of Government interventions implemented between 1985 and 1991 designed to promote food security, locating this analysis in a longer historical context. The study uses data collected over a seven month fieldwork period during 1992. Details of Government programmes were obtained through semi-structured interviews with Government officers and elected representatives at national and regional level. Published and unpublished Government data is used to construct time-series for variations in cropping patterns and production for a wide range of crop types over the period 1960 to 1988. Public responses to hunger and public opinion of state interventions are examined through semistructured individual and group interviews in five villages in different parts of the district. This thesis argues that the persistence of hunger in Kalahandi cannot be directly attributed to the failure of the Government to direct adequate finance and resources to relief and development programmes. It suggests that Government officers have at their disposal a wide range of well-formulated provisions to protect the vulnerable. However a range of factors limit the effectiveness of state interventions when guidelines come to be implemented in practice. In a wider context this study highlights the important role which NonGovernmental Organisations (N.G.O.'s), the media and the law courts may play in promoting food security; and the need to strengthen cooperation between the public, the administration and other key actors, including politicians and N.G.O.'s, in designing and administering measures to combat hunger.

Impacts of great western development on agricultural production in the west of China

Liu, Ge 05 1900 (has links)
Great western development is a regional and preferential reform which began in the mid-1990s, and which intends to promote China's western economy. In this study, I statistically measure the effects of agricultural input growth, technological improvements and most importantly the improvement in institutional efficiency, which is attributed to great western development. This measurement is pursued by first discussing general aspects of Chinese agriculture, including a brief history of China's agricultural economy and politics as well as agricultural policy changes after the reforms. In order to estimate the effects of great western development on the Chinese agricultural production, I use the stochastic frontier production function. This approach is used widely in the field of economics in areas of measuring technical efficiency and policy effects in an industry with random shocks. I accompany this approach with several economic theories such as maximum likelihood estimation (MLE), measurement of technical inefficiency and estimation of technical change in the production function. An important contribution of this thesis is empirical estimation of stochastic frontier production function for great western development and a hypothesis test using the Monte-Carlo method. By maximum likelihood estimation with respect to the stochastic frontier production function, the measurement of the efficiency improvement is produced for the west and the east of China before and after great western development, respectively. A conclusion, made after the empirical analysis, is that great western development has positive effects on agricultural production and productivity in the western China.

The culture of weeds in Western Canada, 1800-1950 : an environmental history

Evans, Clinton Lorne 11 1900 (has links)
This study chronicles the course of an important but little known Canadian war: the war between people and weeds in Western Canada. Arising from intense competition between two groups of immigrants, this conflict started in Europe, spread to Eastern North America and reached a climax on the broad expanses of the Canadian Prairies. By the early 1940s weeds had gained the upper hand on their human competitors and many predicted the end to extensive grain production in the West. This did not occur, however, because of the timely development of 2,4-D and other selective herbicides immediately following the close of World War II. These potent chemical weapons gave prairie farmers new hope at a time when defeat seemed all but certain and they are largely responsible for the expensive standoff between farmers and weeds that persists to this day. Recounting the history of weeds and weed control in Western Canada between 1800 and 1950 serves a number of functions. One is to provide weed scientists with some historical background and an object lesson in the consequences of seeking simple solutions to complex, long-standing problems. Another is to remind historians that we cannot truly understand the history of western settlement and agriculture without understanding the practical issues that dominated the daily lives of past generations of farmers. Yet a third function is to introduce a specific environmental history approach to Canadian historians while, at the same time, encouraging them to pay more attention to recent developments in this American-dominated field. A fourth and final reason for investigating the historical relationship between people and weeds is that it can be used to symbolize something far larger: the relationship between culture and nature in general. An exploration of this issue is made possible by the curious relationship between people and weeds, a relationship summed up by the thesis that weeds are both the the products of and participants in culture. The dissertation concludes with a discussion of recent trends in weed science and, in particular, of the merits of the "new" doctrine of weed management. Canadian historians are lectured on the danger of ignoring nature when writing about history and readers are asked to consider what the terms "nature" and "culture" mean. Do they represent discrete subjects, separate spheres of existence, a dichotomy? Or, are they just different aspects of a larger, more complex whole?

A socio-cultural case study of the Canadian Government's telegraph service in western Canada, 1870-1904 /

Rowlandson, John January 1991 (has links)
In this thesis, the development of a Dominion government telegraph on a portion of the Canadian frontier is analyzed as a formative moment of socialization and cultural expression. It utilizes a socio-cultural framework for understanding the 'experience of space'; notably how changes in presence or access to one another--facilitated by this new mode of communication--are central to this experience. / The thesis argues that the telegraph is crucially related to issues of public confidence. Its approach draws upon recent social and cultural treatments of communication technologies which stress the ways that the material reality of such technologies become part of a larger social and symbolic order. The thesis refers to indicators such as reliability, public works, public interest, competence, and trust to investigate a social apprehension of confidence. 'Confidence', in this case, is not treated as fixed and equally understood, but as something that is invested, shared, built-up and worn down. Thus concerns for and with 'public confidence' help to reveal changes in socio-cultural development.

Revisiting the nesting ecology of the western grebe after 40 years of changes at Delta Marsh, Manitoba

La Porte, Nicholas 19 September 2012 (has links)
Since the 1970s, artificially stabilized hydrology, increased presence of Common Carp (Cyprinus carpio), and invasion by a highly competitive cattail hybrid (Typha x glauca) have changed the nesting ecology of Western Grebes at Delta Marsh, Manitoba. To evaluate the impact of stressors within Delta Marsh on Western Grebes, I repeated surveys originally conducted by Nuechterlein (1975) on the nesting ecology of Western Grebes at Delta Marsh, and compared 2009/2010 breeding success and nesting ecology data with 1973/1974 data. Reductions in breeding success during 2009 and 2010 were primarily due to increases in rates of nesting losses from wave action. Nests destroyed by spawning Common Carp, and depredations by River Otters (Lontra canadensis) further contributed to nesting losses. Reestablishing stands of emergent bulrush around nesting islands and reducing the abundance of carp within the marsh might help return Western Grebe breeding success to rates recorded in the 1970s
