As lavouras de grãos como atividades de desenvolvimento e integração da Região da Grande Dourados ao circuito produtivo nacional

Led to become a national productive Center, the Great Dourados Region, which consists of 40 cities located in the south of the state of Mato Grosso do Sul - Brazil, emerged as a grain productive region from the middle of the 1970s in the 20th century to the beginning of the 21st century. Using modern agricultural techniques, the land organization in this region was ruled by a development policy which was not concerned with the socio environmental aspects of the area. In this context, the present work aims to analyze the development process of the Great Dourados region, through soybean production and its relation to the confinement of the indigenous people present in the Area. This integration happened due to the money and for it, inserting this Region into a national productive pattern which guided the farmers to modern crops, mainly soybean. The land cultivation was not the only productive activity that granted the Region an economic integration, to both the national and international market. From the end of the Paraguay War (1870) to the middle of the 70s, there were at least two other ways to the regional economic integration. One of them happened with the traditional activities of cattle raising and the extraction of the Paraguay tea (maté/ Yerba Mate) from 1870 to 1937, which divided the regional territory into large farmlands focused on the external market. The other way happened with the need to create a market for the agricultural production and for the demand for manufactured goods, which reorganized the regional territory into small farmlands, as a result of colonization projects from 1943 to 1956. Since 1976, with the creation of the Special Program for the Development of the Great Dourados Region (Prodegran), the capitalist relations of production, which were consolidated in the area, were not ruled almost exclusively by the traditional activities of cattle raising and the extraction of the Paraguay tea, in order to create a new accumulation center connected to the modern crops. As this new accumulation center was created, the Region was led to a selective and dependent integration process, in which many farmers changed their accumulation centers to modern grain crops, causing environmental degradation, productive exclusion and ethnical-cultural conflicts with the indigenous community

Restoration of micro data of John Lossing Buck's survey and analysis of the inverse relationship between yield and farm size in rural China in the 1930's

A large scale Chinese agricultural survey was conducted at the direction of John Lossing Buck from 1929 through 1933. At the end of the 1990’s, some parts of the original micro data of Buck’s survey were discovered at Nanjing Agricultural University. An international joint study was begun to restore micro data of Buck’s survey and construct parts of the micro database on both the crop yield survey and special expenditure survey. This paper includes a summary of the characteristics of farmlands and cropping patterns in crop yield micro data that covered 2,102 farmers in 20 counties of 9 provinces. In order to test the classical hypothesis of whether or not an inverse relationship between land productivity and cultivated area may be observed in developing countries, a Box-Cox transformation test was conducted for functional forms on five main crops of Buck’s crop yield survey. The result of the test shows that the relationship between land productivity and cultivated areas of wheat and barley is linear and somewhat negative; those of rice, rapeseed, and seed cotton appear to be slightly positive. It can be tentatively concluded that the relationship between cultivated area and land productivity are not the same among crops, and the difference of labor intensity and the level of commercialization of each crop may be strongly related to the existence or non-existence of inverse relationships.

Puente de ferrocarril sobre el Mittellandkanal en Braunschweig

The bridge over the Mittellandkanal is located in the municipality of Braunschweig, a city of Low Saxony located in Mid-North Germany, between Berlin and Hannover, 50 km away from this last city. The city of Braunschwig has 248.867 inhabitants (December 2010). The orography of the zone is practically even, with some slopes in the surrounding area, with a no important variation of the ground elevation, characterized by a big uniformity and a great visual quality. In this zone the canal flows from west to east, from the Dortmundkanal until the Elbe river, so it has a length of 325,3 km. The normal flora from the zone is farmland with some little forests not very big and not very important. But the Mittellandkanal lies at the North of Brauschweig, that means that in the zone of the canal there is a change between the urban area and the rural area. For this reason in the zone of the bridge we start to find farmlands and forest, however the constructions and buildings are still present in this area. The railway line that is going to be built will unite the North-center of Germany with the North-East of Germany because some of the following factors: •Overstress of the only existing line in the moment that connects Berlin with the North-East extreme of Germany. •No direct connection with the North-Easth Germany with other important German cities from South and West of Germany. •Replacement of the old existing one way line in the area that has to be renewed. •Modernization of the old railway lines of Germany. Schedule order by the European Union and the German Government. The actual lines of the zone do not have the necessary conditions and characteristics to satisfy the demand of the travelers that want to travel all over Germany with the railway avoiding using other transports like plan or car. For these reasons the necessity of the replacement of the old railway line and the aim to create a union with the North-East Germany that has a deficit of transport infrastructures and connections with the rest of the country and Europe. Although the new railway line provokes some disadvantages when constructing it is indispensable to build this railway line. The pass of the railway line through Braunschweig has not been random. The zone Braunschweig-Wolfsburg is a very industrialized area because of some companies like Wolkswagen and too because this zone is an important pass of important line from Berlin, South and East Germany. For all of these reasons the railway line goes through Braunschweig and connects to the city of Wolfsburg first, and after the North-East Germany zone.

Efficiency and environmental indexes to evaluate the sustainability of mineral and organic fertilization in an irrigated melon crop

Melon is traditionally cultivated in fertigated farmlands in the center of Spain with high inputs of water and N fertilizer. Excess N can have a negative impact, from the economic point of view, since it can diminish the production and quality of the fruit, from the environmental point of view, since it is a very mobile element in the soil and can contaminate groundwater. From health point of view, nitrate can be accumulated in fruit pulp, and, in addition, groundwater is the fundamental supply source of human populations. Best management practices are particularly necessary in this region as many zones have been declared vulnerable to NO3- pollution (Directive 91/676/CEE) During successive years, a melon crop (Cucumis melo L.) was grown under field conditions applying mineral and organic fertilizers under drip irrigation. Different doses of ammonium nitrate were used as well as compost derived from the wine-distillery industry which is relevant in this area. The present study reviews the most common N efficiency indexes under the different management options with a view to maximizing yield and minimizing N loss.

Factors Affecting Jaguar and Puma Predation on Livestock in Costa Rica

The wild cats and the livestock farmers are part of the space conflict in the rural areas in Latin America. In this sense, this conflict causes a discomfort among the livestock producers due to the loss of animals and, consequently, it also causes a negative reaction towards the wild cats leading such reaction into the elimination of the wild cats per se. Although, there have been some initiatives have tried to approach such conflict by recommending mitigation and prevention measurements to the producers, these measurements are undertaken without coordination. For this reason, the following project presents a planning tool that can ease the coordination processes undertaken for the solving of the conflict between human beings and wild cats.

Cultural perceptions of space and place in the South Florida *environment

Public opinion polls in the United States reveal that a great majority of Americans are aware and show concern about ecological issues and the need to preserve natural areas. In South Florida, natural resources have been subjected to enormous strain as the pressure to accommodate a growing population has led to rapid development. Suburbs have been built on areas that were once natural wetlands and farmlands, and the impact today shows a landscape where natural places have all but disappeared. This dissertation examines the intersection between the perceptions that individuals living in the South Florida region have with respect to the natural environment and local ecological problems with where their relationship to nature takes place. ^ The research is based upon both quantitative and qualitative data. The principal methodology used in this research is the ethnographic method, which employed the data gathering techniques of in-depth interviewing and participant observation. The objective of the qualitative portion of the study was to determine how people perceive and relate to their immediate environment. The quantitative portion of the study employed telephone survey data from the FIU/Florida Poll 2000. Data collected through this survey provided the basis to statistically test responses to the research questions. ^ The findings show that people in South Florida have a general idea of the relationship between the human population and the environment but very little knowledge of how they individually affect each other. The experience of private places and public spaces in everyday life permits people to compartmentalize cultural values and understandings of the natural world in separate cognitive schemas. The appreciation of the natural world has almost no connection to their personal sense of obligation to preserve the environment. That obligation is only felt in their home space even though the South Florida environment overall struggles desperately with water shortages, land encroachment, and a rapidly expanding human population whose activities continuously aggravate an already delicate natural balance. ^

Land, Power and Technology : Essays on Political Economy and Historical Development

Land Ownership and Development: Evidence from Postwar Japan This paper analyzes the effect of land ownership on technology adoption and structural transformation. A large-scale land reform in postwar Japan enforced a large number of tenant farmers who were cultivating land to become owners of this land. I find that the municipalities which had many owner farmers after the land reform tended to experience a quick entry of new agricultural machines which became available after the reform. The adoption of the machines reduced the dependence on family labor, and led to a reallocation of labor from agriculture to industries and service sectors in urban centers when these sectors were growing. I also analyze the aggregate impact of labor reallocation on economic growth by using a simple growth model and micro data. I find that it increased GDP by about 12 percent of the GDP in 1974 during 1955-74. I also find a large and positive effect on agricultural productivity. Loyalty and Treason: Theory and Evidence from Japan's Land Reform A historically large-scale land reform in Japan after World War II enforced by the occupation forces redistributed a large area of farmlands to tenant farmers. The reform demolished hierarchical structures by weakening landlords' power in villages and towns. This paper investigates how the change in the social and economic structure of small communities affects electoral outcomes in the presence of clientelism. I find that there was a considerable decrease in the vote share of conservative parties in highly affected areas after the reform. I find the supporting evidence that the effect was driven by the fact that the tenant farmers who had obtained land exited from the long-term tenancy contract and became independent landowners. The effect was relatively persistent. Finally, I also find the surprising result that there was a decrease, rather than an increase, in turnout in these areas after the reform.  Geography and State Fragmentation We examine how geography affects the location of borders between sovereign states in Europe and surrounding areas from 1500 until today at the grid-cell level. This is motivated by an observation that the richest places in this region also have the highest historical border presence, suggesting a hitherto unexplored link between geography and modern development, working through state fragmentation. The raw correlations show that borders tend to be located on mountains, by rivers, closer to coasts, and in areas suitable for rainfed, but not irrigated, agriculture. Many of these patterns also hold with rigorous spatial controls. For example, cells with more rivers and more rugged terrain than their neighboring cells have higher border densities. However, the fragmenting effects of suitability for rainfed agriculture are reversed with such neighbor controls. Moreover, we find that borders are less likely to survive over time when they separate large states from small, but this size-difference effect is mitigated by, e.g., rugged terrain.
