This paper uses município-level data in the Northeast region in Brazil to identify and analyze spatial patterns on value of production and yield of fruits and grains. Moran’s I statistics are generated and used to test for spatial autocorrelation, and to prepare cluster maps that locate value of production and yield “hot spots” and “cold spots.” Research results demonstrate that both variables are spatially autocorrelated in some parts of the Northeast, and where correlated, high (low) value of production and yield municípios tend to be located next to high (low) municípios. Maybe more importantly the results set the stage for the use of spatial econometrics for a future multivariate analysis of agricultural value of production and yield of fruits and grains in the Northeast, and particularly in the region of Juazeiro/Petrolina a well- know area of fruit production in Brazil.
COASTAL DEVELOPMENT AND BUREAUCRACY: AQUACULTURE IN PORTUGAL - THE POSSIBLE EMERGENCE OF AN “ANTI-COMMONS TRAGEDY”

Last decades of the 20th century have shown many problems arisen from the emergence of commons mismanagement and under-defined property rights. It’s what we call the “Tragedy of the Commons” (Hardin, 1968), In the 80s, Michelman introduced another problem, this time about the excessive fragmentation of property rights. A new concept, “anticommons” includes the under-use of resources and may come from several sources, including bureaucracy.
There are only a few empirical studies on anticommons tragedies in the real world, most of them focusing on pharmaceutics industry. The main purpose of this paper is to use this conceptualization to study the design and execution of aquaculture policy in Portugal and to introduce the possible emergence of an “anti-commons tragedy” when we approach the difficult process of approval and execution of projects of aquaculture in the Portuguese coastal areas.
ROMAN LEGAL TRADITION AND THE MISMANAGEMENT OF HUNTING RESOURCES

We derive a model of hunting management, adapting the Gordon fisheries model. The conclusions are confronted with Portuguese regulation. Portugal has a Roman legal tradition with respect to hunting property-rights. To this conception, the wild animals constitute res nullius, things without owner that men can appropriate by ocupatio. The classification of free land implicates that the hunter has the freedom of access to hunt in other’s land. This open access tradition is the root-cause of hunting depletion. But the legislator sees it as a form of giving the hunters without land, the possibility of enjoying this activity. This is compatible with the Portuguese tradition, which almost attributes a personality right to the right of hunting.

A etnobotânica é a ciência que ligada à botânica e antropologia estuda as interacções entre os indivíduos e as plantas, em sistemas dinâmicos. Estuda as aplicações e os usos tradicionais das plantas pelo ser humano. É uma ciência multidisciplinar que envolve indivíduos de vários extractos sociais, desde o simples agricultor aos botânicos, antropólogos, médicos, engenheiros, e físicos entre outros.
É a transdisciplinaridade desta área que poderá levar a redefinir e a reequacionar conceitos de crescimento e desenvolvimento que se quer sustentável.
Neste trabalho apresentam-se e discutem-se as utilidades dadas às plantas em três ilhas do Arquipélago dos Açores: São Jorge, São Miguel e Terceira.
