Environmental Justice in the Brazilian Coastal Food Systems: Policies, Institutions, and Knowledges on Small‐Scale Fishers and Energy Development

World Food Policy, Volume 12, Issue 2, November 2026.
ABSTRACT This study explores environmental justice issues in coastal food systems, focusing on conflicts between small‐scale fisheries and the energy sector due to differing goals in managing food and energy sources. It does so by examining the interdependence between institutions, policies, and different types of knowledge; key elements in building ...

Integração, Crescimento E Bem-Estar [PDF]

Brazilian Review of Econometrics, 1997
We present a model of growth for the case of two economies with integrated markets and where transportation costs in the form of iceberg costs are imposed. These costs will have negative impact on growth rates after integration, but will play a key role, together with scale factors, on the location of the firms of the intermediate sector.

Demographic buffering in natural populations: A multi‐level perspective

Journal of Animal Ecology, Volume 95, Issue 8, Page 1298-1310, August 2026.
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Long‐term jaguar demography underscores the ecological value of Amazonian floodplains

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Our results provide the first estimates of recruitment and apparent survival for Amazonian jaguars, key parameters for guiding conservation. We show that seasonal wetlands—the Amazonian floodplain forest and reported estimates from Pantanal and the Llanos—harbour the highest jaguar densities across the species' range.

Cheia de axé (full of axé): Spirituality, resistance, and repair in Pernambuco's Afro‐Brazilian traditional communities

Feminist Anthropology, Volume 7, Issue 1, May 2026.
Abstract This article explores how Afro‐Brazilian communities in Pernambuco respond to state‐led industrial development through culturally rooted practices of resistance and repair. Drawing on archival and ethnographic research in the coastal municipalities of Cabo de Santo Agostinho and Ipojuca, this study traces the effects of Brazil's large‐scale ...

The City as an Anti‐Growth Machine

Antipode, Volume 58, Issue 2, March 2026.
ABSTRACT Logan and Molotch's “urban growth machine” remains foundational in urban theory, describing how coalitions of landowners, developers, and politicians promote urban growth to raise land values. This paper argues that under financialized capitalism, the dynamics have inverted: asset appreciation now outweighs productive investment, and urban ...
