This research examines the merits of hallucinogenic plants considered and/or psychoactive substances, such as Cannabis sativa and Ipomoea violacea, using the isotope rates of stable isotope of oxygen (18O) and nitrogen (15N), continuing projects already developed by the research group at the Center for Stable Isotope (CIE), which evaluated the isotopes carbon-13. This paper helps in creating a database that we intent to use in evaluation of each plant merit. Through the IRMS (Isotope-Ratio Mass Spectrometry) technique, it has shown that some of the 24 samples of marijuana (Cannabis sativa L.) evaluated were similar to those grown in the regions of Fairbanks and Tanacross Alaska, USA. In turn, the 50 samples of Ipomoea violacea, coming from Botucatu (SP) and Três Lagoas (MS), got their differences detected, in order to clearly identify the discrepancies between their growing regions. Thus, it was possible not only to track the geographical differences between marijuana samples collected from different regions, but also evaluate the isotopic variation of leaf, flower and seed of Ipomoea violacea. With this database, it was possible to determine the origin region of the drug and/or detect where the cultivation was carried out, aiding in the search of the traffic control agencies, such as the Federal Police in Brazil

From the agri-food crisis of 2007/2008, we live an intensifying period in the global land rush. The land grabbing is analyzed as a process that occurs on a global scale, especially to countries in Africa and Latin America, the main targets of the current global competition for land, because beyond the earth have low prices and the legislation be flexible, low and ineffective supervision of the state (especially in the issue of environmental and labor laws), also have vast tracts of arable land, with fertile soils and high availability of water resources (the latter element has become relevant in that case analysis). In addressing the land foreignization in the XXI century it is necessary to speak about the issue of biofuels and bioenergy, since it is these that define the current phase of land foreignization in Brazil. In the 1970s occurred the first incentive to produce ethanol in the sugarcane cultivation, with the policy of the National Alcohol Program (PROALCOOL). From the 2000s this interest again sharpened up and foreign capital began to see in Brazil a great opportunity for a production facility and purchase of old agro-processing plants that were implanted in PROALCOOL period but who were disabled. This is the case of Umoe Bioenergy, Norwegian company that in 2006 started its production in the municipalities of Narandiba and Sandhurst, located in the Pontal do Paranapanema region that, in turn, is the region of São Paulo with larger agrarian conflicts, settlements land reform, land grabbing and high poverty rates...

This paper presents methodological considerations related to the study of the plant lexicon of the Juruna ethnic group, an indigenous people of the Xingu Indigenous Park, Mato Grosso State, Brazil. The language of this ethnic group, along with that spoken by the Xipaya, belongs to the Juruna family of the Tupi stock. It is a tonal language with SOV syntactic structure (Fargetti 1992, 2007), and presents interesting processes of reduplication (Fargetti 1997). Part of our broader research project on the lexicology and lexicography of the language, research on the Juruna plant lexicon is still in development, together with studies of other semantic fields such as birds, material culture, and kinship relations. However, it is already possible to see interesting linguistic issues involving word formation, as well as issues of the relationship between language and culture (especially those related to “perspectivism”). These issues are presented in this paper.
