Socio-economic conditions of the pond owners of Demra, Dhaka

On the basis of fish culture status 96 ponds of the study area were classified into 4 categories like wild stock (27%), extensive culture (24%), improved extensive culture (33%) and semi-intensive culture (16%). Percentage of small, medium and large ponds were 38, 44, and 18 respectively whereas education levels below SSC, below Bachelor and above were 43, 38 and 19 respectively and single owners belonged to 54% of the ponds. Per hectare yields of extensive, improved extensive and semi-intensive categories of culture were 1.3, 2.12 and 4.0 metric tons respectively and their net return were 46, 63 and 92 thousand taka respectively. Considering the problems of fish culture, multiple ownership was found to be the most important one.

Changes of traditional farming systems and their effects on land degradation and socio-economic conditions in the Inle Lake region, Myanmar

At many locations in Myanmar, ongoing changes in land use have negative environmental impacts and threaten natural ecosystems at local, regional and national scales. In particular, the watershed area of Inle Lake in eastern Myanmar is strongly affected by the environmental effects of deforestation and soil erosion caused by agricultural intensification and expansion of agricultural land, which are exacerbated by the increasing population pressure and the growing number of tourists. This thesis, therefore, focuses on land use changes in traditional farming systems and their effects on socio-economic and biophysical factors to improve our understanding of sustainable natural resource management of this wetland ecosystem. The main objectives of this research were to: (1) assess the noticeable land transformations in space and time, (2) identify the typical farming systems as well as the divergent livelihood strategies, and finally, (3) estimate soil erosion risk in the different agro-ecological zones surrounding the Inle Lake watershed area. GIS and remote sensing techniques allowed to identify the dynamic land use and land cover changes (LUCC) during the past 40 years based on historical Corona images (1968) and Landsat images (1989, 2000 and 2009). In this study, 12 land cover classes were identified and a supervised classification was used for the Landsat datasets, whereas a visual interpretation approach was conducted for the Corona images. Within the past 40 years, the main landscape transformation processes were deforestation (- 49%), urbanization (+ 203%), agricultural expansion (+ 34%) with a notably increase of floating gardens (+ 390%), land abandonment (+ 167%), and marshlands losses in wetland area (- 83%) and water bodies (- 16%). The main driving forces of LUCC appeared to be high population growth, urbanization and settlements, a lack of sustainable land use and environmental management policies, wide-spread rural poverty, an open market economy and changes in market prices and access. To identify the diverse livelihood strategies in the Inle Lake watershed area and the diversity of income generating activities, household surveys were conducted (total: 301 households) using a stratified random sampling design in three different agro-ecological zones: floating gardens (FG), lowland cultivation (LL) and upland cultivation (UP). A cluster and discriminant analysis revealed that livelihood strategies and socio-economic situations of local communities differed significantly in the different zones. For all three zones, different livelihood strategies were identified which differed mainly in the amount of on-farm and off-farm income, and the level of income diversification. The gross margin for each household from agricultural production in the floating garden, lowland and upland cultivation was US$ 2108, 892 and 619 ha-1 respectively. Among the typical farming systems in these zones, tomato (Lycopersicon esculentum L.) plantation in the floating gardens yielded the highest net benefits, but caused negative environmental impacts given the overuse of inorganic fertilizers and pesticides. The Revised Universal Soil Loss Equation (RUSLE) and spatial analysis within GIS were applied to estimate soil erosion risk in the different agricultural zones and for the main cropping systems of the study region. The results revealed that the average soil losses in year 1989, 2000 and 2009 amounted to 20, 10 and 26 t ha-1, respectively and barren land along the steep slopes had the highest soil erosion risk with 85% of the total soil losses in the study area. Yearly fluctuations were mainly caused by changes in the amount of annual precipitation and the dynamics of LUCC such as deforestation and agriculture extension with inappropriate land use and unsustainable cropping systems. Among the typical cropping systems, upland rainfed rice (Oryza sativa L.) cultivation had the highest rate of soil erosion (20 t ha-1yr-1) followed by sebesten (Cordia dichotoma) and turmeric (Curcuma longa) plantation in the UP zone. This study indicated that the hotspot region of soil erosion risk were upland mountain areas, especially in the western part of the Inle lake. Soil conservation practices are thus urgently needed to control soil erosion and lake sedimentation and to conserve the wetland ecosystem. Most farmers have not yet implemented soil conservation measures to reduce soil erosion impacts such as land degradation, sedimentation and water pollution in Inle Lake, which is partly due to the low economic development and poverty in the region. Key challenges of agriculture in the hilly landscapes can be summarized as follows: fostering the sustainable land use of farming systems for the maintenance of ecosystem services and functions while improving the social and economic well-being of the population, integrated natural resources management policies and increasing the diversification of income opportunities to reduce pressure on forest and natural resources.

Análisis de la renovación urbana como estrategia de recuperación del centro histórico de bogotá : estudio de caso barrio Santa Bárbara Colonial (Nueva Santa Fé), en el periodo 1976-2000

El presente estudio de caso se propuso analizar la renovación urbana como estrategia de recuperación del centro histórico de Bogotá, utilizando como objeto de investigación, el proceso de renovación urbana que atravesó el Barrio Santa Bárbara Colonial, hoy conocido como Nueva Santa Fe, en el período 1976 (fecha de planteamiento del proyecto) a 2000 (año en el que se implementa el P.O.T), lo que significa nuevas condiciones en términos urbanos para ejecutar proyectos dentro de la ciudad), para lo cual se va a utilizar el concepto de vivienda, dentro de la renovación urbana, como variable que servirá de hilo conductor en el desarrollo del tema. El concepto de renovación que concierne a esta investigación está enmarcado en la década de los 70s y 80s, para lo cual se hace una breve referencia a la década de los 50s y 60s como antecedente de la creciente tendencia que tuvo la renovación urbana en Europa, continente que ha marcado una fuerte influencia en Latinoamérica y a su vez en Colombia. Con base a dicha estructuración, se da cuenta del tipo de investigación a desarrollar, una investigación cualitativa interesada en reflexionar sobre la forma en que se desarrolló la renovación urbana en el sector, haciendo evidente sus falencias y más adelante, los errores que se siguen cometiendo en los planteamientos actuales que tienen que ver con este tratamiento.

Este artículo constituye un recorrido por las características económico-sociales y políticas del periodo 1976-2000, correspondiente a la reforma del sistema financiero en Argentina y al establecimiento del modelo económico rentístico-financiero. El comienzo del análisis se da en tiempos de la dictadura militar instaurada en 1976. Luego, el estudio se centra en el gobierno radical y se continúa con Ias dos presidencias justicialistas a cargo de Carlos Menem. Algunas de las características de esta época son: liberalización de la economía, creciente hegemonía del capital financiero, y fuerte crecimiento de la deuda externa.

La réception critique des auteurs nés à l'étranger et de leurs oeuvres dans trois périodiques québécois : Voix et images, Lettres Québécoises et Châtelaine (1976-2000)

En 1986, Robert Berrouët-Oriol dénonçait le silence de la critique québécoise envers ce qu'il a appelé les écritures migrantes. Selon lui, on n'octroyait pas à ces textes la place qui leur était due au sein du discours critique. Seule une analyse exhaustive de la réception critique pourrait révéler les mécanismes d'exclusion en vigueur dans le champ littéraire québécois. Tel a été l'objectif de ce mémoire. Le premier chapitre présente une mise en contexte de la réalité vécue par les nouveaux arrivants au Québec. Un panorama des grands enjeux sociaux, politiques et culturels des dernières vingt-cinq années du XXe siècle est proposé. Ce tableau de l'époque se voit complété par un survol des différentes politiques d'intégration mises en place par les gouvernements pour accueillir les immigrants. Enfin, une rapide étude du phénomène des écritures migrantes, inscrites au coeur de la littérature québécoise, clôt ce chapitre. Par la suite, les données sociologiques des auteurs du corpus sont analysées de façon quantitative, afin d'obtenir de ces derniers un profil juste et signifiant. Selon cette même perspective quantitative, nous examinons également les articles colligés dans le but d'y déceler des tendances temporelles et des particularités propres à chacun des périodiques. Le troisième chapitre est consacré à une analyse de la terminologie utilisée par les critiques pour désigner les auteurs nés à l'étranger qui sont traités dans les pages des périodiques sélectionnés. Nous verrons à quels moments et dans quelles circonstances un auteur se voit attribuer une dénomination québécoise ou participant du marquage d'une altérité. Ce mémoire s'achève sur une étude approfondie des thématiques, tout autant celles abordées par les auteurs nés à l'étranger dans leurs ouvrages que relevées par les critiques qui en font la mention.

Variación estacional e interanual de la biomasa fitoplanctónica y concentraciones de clorofila A, frente a la costa peruana durante 1976 - 2000

La distribución de las diversas masas de agua influyó en los patrones espaciales y temporales de los volúmenes de fitoplancton y clorofila a. Los eventos EN fueron negativos para la producción primaria, registrándose valores <1,0 mL/m3, y las especies oceánicas son las más abundantes. Los periodos fríos o "la Niña" favorecieron la biomasa fitoplanctónica alcanzando volúmenes promedio >3,0 mL/m3; la composición del fitoplancton también varía en periodos fríos, con ampliación de las áreas de afloramiento y dominan especies pequeñas de alta tasa de reproducción de las primeras fases de la sucesión. Se observaron cambios significativos entre 1976-1987 y entre 1988-1999, asociados a periodos de baja y alta producción primaria.

The new blockbuster film sequel : changing cultural and economic conditions within the film industry

Film sequels are a pervasive part of film consumption practices and have become an important part of the decision making process for Hollywood studios and producers. This thesis indicates that sequels are not homogenous groups of films, as they are often considered, but offer a variety of story construction and utilize a variety of production methods. Three types of blockbuster sequel sets are identified and discussed in this thesis. The Traditional Blockbuster Sequel Set, as exemplified by Back to the Future (1985, 1989, 1990) films, is the most conventional type of sequel set and capitalizes on the winning formula of the first film in the franchise. The MultiMedia Sequel Set, such as The Matrix (1999,2003) trilogy, allows the user/viewer to experience and consume the story as well as the world of the film through many different media. The Lord a/ the Rings (2001, 2002, 2003) set of films is an illustration of The Saga Sequel Set where plot lines are continuous over the entire franchise thus allowing the viewer to see the entire set as a unified work. The thesis also demonstrates how the blockbuster sequel sets, such as the Pirates a/ the Caribbean (2003, 2006, 2007) franchise, restructure the production process of the Hollywood film industry.
