The paper argues that the discourse of palm oil production for biodiesel constitutes a frontier ideology. Around it, the representation of space endowed with comparative advantages is reedited. To do so, it is based on data from the United States Department of Agriculture, the Brazilian Agricultural Research Corporation, the National Agency for Petroleum, Natural Gas and Biofuels, the Ministry of Development, Industry and Foreign Trade, and in company reports, as well as interviews with company representatives. In addition to the introduction and conclusion, in the first part examines the palm oil production, consumption and global trade, indicating that it is destined to the food, cosmetics and hygiene industry. The second shows the new frontier ideology promoted by palm oil at the beginning of the 21st century, highlighting the analytical pertinence of this category to interpret territorial dynamics of the Amazonia agrarian space.

The political-economy of the agriculture frontier in the Brazilian state of Mato Grosso, in the southern sections of the Amazon Region, is analysed in order to question the productivist argument commonly presented by the agribusiness sector. The assessment makes use of the category of rent considered as a proportion of exchange value diverted from production for the payment to the landowners and its class-based allies. The frontier in Mato Grosso has had basically three main rent extraction periods: a first moment when rent was forged by the state apparatus (1970s-1980s), a second period with serious turbulence and a macroeconomic transition (1980s-1990s) and a third phase with more complex flows of rent due to the neoliberalization of agribusiness (since the late 1990s). At the frontier of agribusiness, agricultural activity depends on combined strategies of rent creation and rent extraction. Empirical results suggest that rent is more than just the extraction of value from the use of land, but there is a wider capture of value from the network of relations that maintain land in production. Rent derives from land through the formation of a powerful network stateland-owners-private agroindustrial sector that provides the conditions for rent extraction. [ABSTRACT FROM AUTHOR]

The aim of this article is to discuss the gradual insertion of the state in the process of regulating and supervising yerba-mate activities in Brazil. The focus is concentrated on actions undertaken by means of laws and decrees and in the creation of institutions dedicated to monitoring the cultivation, use and commercialization of yerba mate. The state's activities and those of the institutions expanded at the same time as the formation and consolidation of the yerba-mate complex covering the states of Paraná, Santa Catarina, Mato Grosso and Rio Grande do Sul. The text is divided into five sections. First, it presents a general panorama of the yerba-mate complex, highlighting the production process and the units which are part of this complex. It then goes on to highlight the first laws to be approved by the provinces and the imperial government in the nineteenth century. Next, it analyses the regulatory mechanisms approved between 1900 and 1938, and actions taken by the regional yerba-mate institutes. The penultimate section discusses several initiatives undertaken by the National Mate Institute, during its existence from 1938 to 1966. Finally, the article presents its conclusions.
