Previous issue date: 2017-03-31 / This work aims to evaluate the Soy Moratorium, an industry led initiative to curb deforestation in the Amazon Biome. Under this agreement, all signatories commit to not buy soybeans produced in lands deforested after July 2006. There is no effective evaluation of this program and the literature in economics have not addressed the question of whether a market ban could reduce deforestation. My main specification is a triple-difference estimate and I find that, unlike previous evaluations, the moratorium had no effect to reduce deforestation. / Este trabalho tem por objetivo avaliar a Moratória da Soja, uma iniciativa privada para reduzir o desmatamento no Bioma Amazônia. Sob esse acordo, todos os signatários se comprometem a não comprar a soja produzida em terras que foram desmatadas a partir de julho de 2006. Até hoje, não foram feitas boas avaliações desse programa e a literatura de economia desconhece a efetividade de embargos a produtos como ferramenta de combate ao desmatamento. A principal especificação econométrica deste trabalho consiste numa estimação em diferenças triplas e resulta, diferentemente das avaliações anteriores, na avaliação de que a moratória não foi capaz de reduzir o desmatamento na Amazônia.

Land use change and land use displacement dynamics in Mato Grosso and Pará, Brazilian AmazonGollnow, Florian 23 January 2018 (has links)
Die Nachfrage nach Agrarerzeugnissen gilt als zentrale Ursache für den Verlust weltweit wichtiger Ökosysteme. In Brasilien hat speziell die Ausweitung der Sojaproduktion zur Abholzung tropischer Wälder und Savannen geführt. Zumeist werden neu gerodete Flächen als Rinderweiden genutzt und vormalige Weiden für den Sojaanbau umgewandelt. Diese Entwicklung führt zu der Annahme, dass die Ausweitung der Sojaproduktion indirekt für die Rodung verantwortlich ist. Staatliche Umweltpolitiken und die Selbstverpflichtung der Sojaindustrie haben seit 2004 zu einer Verringerung der Abholzung beigetragen. Vor diesem Hintergrund zielt die vorliegende Dissertation darauf ab, ein vertieftes Verständnis der Wechselwirkungen zwischen Soja- und Rinderwirtschaft zu erlangen. Im Fokus stehen räumliche und zeitliche Dynamiken von Landnutzung und Landnutzungsverdrängung in Mato Grosso und Pará, einer der dynamischsten Regionen Brasiliens. Für diese Bundesstaaten werden Landnutzung und Landnutzungsverdrängung im regionalen Kontext, auf Grundstücksebene und mithilfe von Szenarien untersucht. Die Ergebnisse zeigen, dass die Strategien zur Verringerung der Abholzung Einfluss auf die Dynamiken der Landnutzung und Landnutzungsverdrängung hatten. Die durch die Ausweitung des Sojaanbaus hervorgerufene Verdrängungsprozesse haben sich nach der Implementierung der Umweltschutzstrategien verringert. Auch die Abholzung auf einzelnen Grundstücken in Mato Grosso ging zurück. Zugleich zeigt die Analyse, dass die Selbstverpflichtung der Sojaindustrie durch indirekte Abholzung teilweise untergraben wird. Die Ergebnisse der Szenarien unterstreichen die regionale Dynamik und speziell die Risiken einer weiteren Ausweitung von Rinderweiden. Insgesamt legen die Ergebnisse nahe, dass auf Reduktion der Abholzung abzielende Strategien die Wechselwirkungen von Soja- und Rinderwirtschaft beachten müssen. Dies erfordert eine verstärkte Zusammenarbeit von Rinderwirtschaft, Sojaindustrie und staatlichen Organisationen. / Demands for agricultural commodities are a major threat for some of the most valuable ecosystems in the world. The expansion of the agricultural sector in Brazil, fueled by global demands for soybeans, contributed to the loss of tropical and savanna ecosystems. However, most deforestation was caused by pastures, raising concerns about land use displacement processes between soybean expansion and cattle ranching. Promising, reductions of deforestation were observed following the implementation of governmental strategies and zero-deforestation supply chain commitments. This thesis aims to contribute to the understanding of spatial and temporal dynamics of soybean expansion and cattle ranching, driving deforestation in one of the most dynamic agricultural expansion and deforestation frontier of Brazil, in Mato Grosso and Pará. In this region, land use displacement describes the conversion of pasture to soybean followed by deforestation for cattle ranching at another location. This process was assessed at regional and property-level. Moreover, scenario analysis was applied to identify regional and subregional dynamics of land use changes. The results indicated that environmental governance affected regional and local land use dynamics and displacement processes. Distal displacement processes between soybean expansion and deforestation were significant, contributing to deforestation, but declined subsequently to the implementation of environmental policies. Likewise, deforestation at property-level declined following the policy implementations. However, the effectiveness of the zero-deforestation supply chain commitment was found to be at risk due to property-level displacement deforestation. Additionally, the scenario analysis emphasized the importance of subregional dynamics and identified risks of future deforestation. Integrating efforts between supply chain (soy and cattle) and governmental actors may be crucial to reduce deforestation in the Amazon.
