Agricultura orgânica e a sustentabilidade
No full textThe preservation of ecosystems is a concern of those who develop organic agriculture. Using
this model of exploitation is possible to preserve ecosystems and, gradually, recovering some areas that may
eventually be degraded by continuous exploration through the conventional model of agriculture. Organic
agriculture is beginning to establish production systems based on a set of procedures involving the plant, the
soil and climatic conditions. And the goal of this type of agriculture is to produce a wholesome food and their
characteristics and flavor, to meet consumer expectations. Unlike conventional agriculture, which has a great
concern about the financial return, organic agriculture is concerned with the environment and human health.
The theoretical framework that would serve as the basis for organic agriculture was designed by Sir Albert
Howard, in the early twentieth century. In less than a century , organic agriculture has expanded around the
world , changing food consumption , how to farm the land , and, above all , showing that it is possible to
produce , but without harming the environment . Underpinned by the principles of sustainability, it also has a
great relationship with the health and quality of life of the human being, and therefore an alternative to
sustainable development.A preservação dos ecossistemas é uma preocupação daqueles que desenvolvem a agricultura
orgânica. Utilizando-se desse modelo de exploração é possível preservar os ecossistemas e, de forma gradativa,
recuperar-se algumas áreas que por ventura estejam degradadas, pela exploração contínua através do modelo
convencional de agricultura. A agricultura orgânica tem por princípio estabelecer sistemas de produção com
base num conjunto de procedimentos que envolvam a planta, o solo e as condições climáticas. E, o objetivo
dessa modalidade de agricultura é produzir um alimento sadio e com suas características e sabor originais,
visando atender às expectativas do consumidor. Ao contrário da agricultura convencional, que possui uma
grande preocupação quanto ao retorno financeiro, a agricultura orgânica preocupa-se com o meio ambiente e
com a saúde humana. A concepção teórica que serviria de base para a agricultura orgânica foi idealizada por
Sir Albert Howard, no início do século XX. Em menos de um século, a agricultura orgânica expandiu-se por
todo o mundo, mudando o consumo de alimentos, a forma de exploração da terra, e, principalmente, mostrando
que é possível se produzir, sem, contudo, agredir o meio ambiente. Apoiada nos princípios da sustentabilidade,
ela também possui uma grande relação com a saúde e a qualidade de vida do ser humano, sendo, portanto, uma
alternativa para o desenvolvimento sustentável
Neotropical freshwater fisheries : A dataset of occurrence and abundance of freshwater fishes in the Neotropics
No full textThe Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change.
