“…La question de la localisation des productions agricoles a connu peu de développements récents (Capt et Schmitt 2000; Kellerman 1989a et b) et évolue entre la théorie ricardienne des avantages comparatifs et celle des cercles concentriques de Von Thünen (1826). La nouvelle économie géographique impulsée par Krugman (1991a et b) s'intéresse aux déterminants de la localisation des activités industrielles.…”

"Nous analysons dans cet article l'impact de l'ouverture des marchés sur la localisation des activités agricoles et agro-alimentaires entre deux régions représentant de manière stylisée l'Union européenne et le reste du monde. L'analyse repose sur un modèle d'économie géographique qui considère certaines caractéristiques de l'agriculture et des marchés de produits alimentaires. Dans un cadre de marché en concurrence monopolistique o� les produits sont différenciés horizontalement et verticalement, il appara�t que l'ouverture du marché induit dans tous les cas une baisse de la production communautaire. Seule une forte différentiation des produits selon leur origine géographique permet de limiter cette baisse." Copyright 2007 Canadian Agricultural Economics Society.

“…There are numerous studies on the development of intensity equations for analyzing spatial structure of agricultural land use (Kellerman 1983). In a more specialized review, Kellerman (1989a, 198913) finds the relaxation of some assumptions and applications of the basic rent model of agricultural location theory.…”

Important characteristics of spatial agricultural production functions are derived by introducing a non‐negative curvilinear spatial demand function for production input intensities. Given the usual neoclassical rationale assumptions of spatial demand for capital and labor inputs under competitive environment of farming in developing agricultural economies, the optimal production levels are determined by optimizing spatial demand for production inputs. Decreasing price‐to‐transport costs ratio (that is, decrease in the prices of capital goods or increase in freight rates) and increasing wage‐to‐travel costs ratio (that is, increase in labor wages or decrease in the travel rate) expand the limits of the (spatial) optimal boundary of the demand for agricultural capital goods and labor input respectively. These effects occur on account of the operation of (positive) spatial price gradient and (negative) wage‐gradient in the market region. It may be noted that elasticities of demand for production factors are spatially variant and have significant effects on the alterations in the structure of agricultural production. However, the spatial optimal solution of production has a complicated relationship with them. The price elasticity has negative and wage elasticity has positive spatial gradients in the market region. Farmers located in the periphery of the market region are not much affected by the proportionate changes occurring in the prices of agricultural capital goods but are more sensitive to the proportional changes in labor wages. Because of a decreasing trend in capital input demand and increase in labor input with distance from the market, capital‐product diminishes with a decreasing rate and labor‐product increases with an increasing rate in the spatial structure of agricultural production. As a result, capital‐labor ratio falls toward zero, which raises profit rate per unit of capital investment especially in the outer part of the market region. The equilibria of optimal production with price elasticity as well as of capital intensity with labor employment (that is, capital‐labor ratio as unity) determine spatial limits of the optimal production zone which is shifted outward subject to the provision of cheap transportation, stabilizing market prices and/or increasing wage rate at the market center. It will help in extending outwardly the optimal spatial limits of capital investment and will mobilize capital resources of farmers in the periphery for efficient and competitive capital‐dominated farming.

“…A intensificação da produção observada no sul do Pará deve-se à presença da infraestrutura de transporte, a qual permite escoar a produção tanto para o mercado de 1968-1978e 1985-1989. No período 1979-1984, a soja continuou ocupando grande áreas de pastagens naturais, mas em um ritmo muito mais lento, e incorporando grandes áreas de outras culturas, que estavam em decadência na região (principalmente o arroz).…”

“…, , , (Barlowe, 1965). Além destes, Kellerman (1989) cita também a cobrança de taxas para determinadas áreas, variações nos preços de mercado, diferenciação de preços, o transporte marítimo, diferenciação nos preços do frete com a variação da distância, consumidor como pagador pelo transporte, variação nos custos de produção, variação no tamanho das propriedades, presença de poli cultura, informação imperfeita e produtores com outros objetivos além da maximização dos lucros. Todos estes fatores fazem com que os anéis de von Thünen deixem de ser círculos concêntricos e passem a assumir as mais variadas formas, de acordo com as vantagens de cada produto para determinadas regiões.…”

Gostaria de agradecer... A Deus, que permitiu que este projeto se realizasse plenamente e de maneira bastante tranqüila, apesar do intenso trabalho. Ao Prof. José Vicente Caixeta Filho (para mim a melhor definição da palavra professor) pelo seu empenho e dedicação a este projeto e a este aluno. A todo o pessoal do Imazon, especialmente ao Eugênio Arima, Beto Veríssimo, Paulo Barreto, Rodney, Carlos, André e ao grande parceiro Marky Brito, que confiaram este importante trabalho a mim, dando a chance a um paulistano de conhecer um mundo tão singular como a Amazônia. Aos amigos do curso de Economia Aplicada da ESALQIUSP, destacando o Bruno, o Zé, o Marcelo, o Glauco, o Robson, o Dautro, o Ari, o Leopoldo e o Paulinho, pelos bons momentos que passaram e pelas amizades que ficaram. Ao pessoal do Imaflora que sempre apoiou e incentivou o projeto, contribuindo imensamente para a riqueza das discussões deste tema que é, por natureza, bastante complexo. A todas as pessoas que contribuíram para o sucesso das viagens, em especial o Sr. Vitório Cel1a, Manoel Amaral, Rubens Gomes, Vicente Godinho (EMBRAP A Vilhena), Luis Antônio Pagot (Hermasa), Alfredo Homma (EMBRAPA CPATU) e à FAMATO. À CAPES e à Fundação Fard, que deram o suporte financeiro a este projeto.
