‘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
