‘Land grabbing’ e ‘Green grabbing’: Uma leitura da ‘corrida na produção acadêmica’ sobre a apropriação global de terras

A partir de 2008, houve uma extensa produção e publicação de artigos acadêmicos, basicamente em inglês, sobre um fenômeno denominado corrida mundial por terras ou land grabbing (apropriação de terras). Depois de cinco ou seis anos, essa produção se mantém, mas com construções teórico-empíricas mais elaboradas – inclusive com a reformulação de conceitos e criação de outros como green grabbing (apropriação verde) e water grabbing (apropriação da água) –, especialmente porque as primeiras reflexões eram excessivamente centradas em dados quantitativos e escala (quantidade de hectares transacionados), em grandes investimentos estrangeiros em terras agrícolas e voltados para estudos de casos sobre a compra de terras no Continente Africano. O objetivo deste artigo é retomar os termos do debate, relendo argumentos e discutindo formulações teóricas (inclusive o próprio conceito de land grabbing), procurando construir diálogos teóricos e agendas de pesquisas acadêmicas no Brasil, pois o mesmo – além ser um país com históricos problemas agrários como a concentração da terra – é marcado por investimentos externos, mas também incentiva a apropriação privada de terras em outros lugares e países, o que resulta na expansão das fronteiras agrícolas e gera conflitos e disputas territoriais. After 2008, there has been an extensive production and publication of academic articles in English, dealing with a phenomenon called global land rush or land grabbing. After five or six years, such academic production continuous but more elaborated theoretically and with larger empirical evidences, including some conceptual reformulations and creation other concepts like green grabbing and water grabbing. This happened especially because the first studies were overly focused on quantitative data and scale (land deals in hectares), considering large foreign investment in agricultural land and focused on case studies on the purchase of land on the African continent. This article aims to resume the terms of the debate, discussing some arguments and theoretical formulations – including the concept of land grabbing –, looking for reflexions, theoretical dialogue and academic research agenda in Brazil. Besides being a country with historical agrarian problems, like the concentration of landownership, Brazil is has foreign investments, but it also encourages private investments and land deals, resulting in the expansion of the agricultural frontier, generating conflicts and territorial disputes in other countries

Fundamental Limits on the Speed of Evolution of Quantum States

This paper reports on some new inequalities of Margolus-Levitin-Mandelstam-Tamm-type involving the speed of quantum evolution between two orthogonal pure states. The clear determinant of the qualitative behavior of this time scale is the statistics of the energy spectrum. An often-overlooked correspondence between the real-time behavior of a quantum system and the statistical mechanics of a transformed (imaginary-time) thermodynamic system appears promising as a source of qualitative insights into the quantum dynamics.Comment: 6 pages, 1 eps figur

Formulation of Protein-Rich Chocolate Chip Cookies Using Cricket (Acheta domesticus) Powder

In theWestern world, the successful introduction of insect consumption may need awareness of insect ingredient benefits, and consumers’ anticipation of insect-based foods with sensory quality is crucial. The objective of this study was to develop protein-rich nutritional chocolate chip cookies (CCC) from cricket powder (CP) and analyze their physicochemical, liking, emotions, purchase intent, and sensory properties. The CP additions levels were 0%, 5%, 7.5%, and 10%. Chemical composition, physicochemical, and functional properties were analyzed using individual and mixed CP and wheat flour (WF). The proximate composition of CP mainly consisted of ash (3.9%), fat (13.4%), and protein (60.7%). In vitro protein digestibility of CP was 85.7%, whereas the essential amino acid score was 0.82. The CP inclusion significantly impacted the WF functional and rheological properties in all given incorporation levels in flour blends and doughs. The incorporation of CP produced darker and softer CCC, resulting from the effect of the CP protein. Adding 5% of CP did not impact the sensory attributes. Purchase intent and liking improved by using 5% of CP after panelists had revealed the beneficial information regarding CP. Concerning emotion terms, “happy” and “satisfied” significantly decreased while the negative emotion term “disgusted” increased among the highest CP substitute levels (7.5% and 10%) after beneficial information. Overall liking, flavor linking, education, consumption intent, gender, age, and positive emotion term “happy” were significantly assertive predictors affecting purchase intent.Hatch fund at Universidad National de Agriculture AL-UNAG-028-202

Acaparamiento de tierras y acumulación capitalista: aspectos clave en América Latina

__Abstract__ We introduce this special issue by explaining seven characteristics of land grabbing in Latin America. These features are not unique to the region. By highlighting them – arguing, for instance, that a key aspect in Latin America is intra-regional land grabbing driven by (trans)Latina companies – we hope to inspire new cross-regional comparisons to understand the dynamics of “global” land grabbing. Our focus on Latin America challenges some problematic generalisations in the literature, for instance, that land grabs occur mainly in fragile states. We interrogate the relationship between land grabbing and the “foreignisation” narrative, and the need to revisit the broader question of land concentration. Thus we build upon the literature locating land grabs and the land question within the political economy of global capitalism
