CONDICIONES INICIALES PARA UNA POLÍTICA DE DESARROLLO Y DEL MEDIO AMBIENTE. Un enfoque a partir de los derechos concretos a la vida

Resumen En este ensayo se pretende analizar, críticamente, un aspecto que consideramos crucial en toda propuesta de desarrollo, ya sea que éste se entienda como “desarrollo económico”, como “desarrollo humano sostenible”, o como desarrollo a secas: los criterios formales de decisión y sus correspondientes marcos categoriales. Estos criterios se insertan necesariamente en un sistema de coordinación del trabajo social, y condicionan los fines y las metas de la acción. Además, lo hacemos teniendo especialmente en cuenta aquellos rasgos estructurales del subdesarrollo capitalista que creemos necesario enfrentar y superar en toda propuesta de desarrollo: el desempleo, las desigualdades sociales y regionales, la exclusión social y la destrucción del medio ambiente. El análisis presupone una imagen del ser humano que concibe a éste como un sujeto de derechos concretos a la vida, imagen que parte del trabajo humano en el conjunto de la división social del trabajo, y por tanto, de un sujeto en comunidad. Adjudica al ser humano determinados derechos a la vida que tienen que impregnar a la sociedad entera para que pueda ser realmente una sociedad libre.   Abstract This paper attempts analyze, in a critical way, a crucial issue concerning every development proposal: the formal criteria of decision and their respective theoretical frameworks, either we talk about economic development, human development or just development. These criteria are necessarily inserted in a social labor coordination system and they determine those ends and goals of the human action. Moreover, we emphasize those structural features from capitalist underdeveloped countries that are urgent to face and overcome: unemployment, social and regional inequalities, social exclusion and environment destruction. Analysis we do presupposes the human being conceived as a person with concrete rights of live, as from the human labor in the whole of social labor division, and therefore, as a person in a community. Every society, in order to be a free society, must to assign these concrete rights of live to every human being.

A INFLUÊNCIA DO ESTOQUE DE MATÉRIA ORGÂNICA DO SOLO EM FRAGMENTOS FLORESTAIS DE MATA ATLÂNTICA

In the Atlantic forest biome, very fragmented and with high diversity of ecosystems, of species, and high endemism degree, the maintenance of the status of the biological diversity presupposes the recovery and conservation of the mosaic of existent fragments. In that context, the use of global functional indicators for the evaluation of the state of conservation of fragments, for the character of systemic synthesis that they act becomes interesting. In tropical forests ecosystems, the surface organic matter stock of the soil is one functional indicator of the decomposition subsystem and they are responsible in big measured by the maintenance and survival of the communities of those ecosystems group. The human action when fragmenting the forest ecosystems, as it substitutes the native forest for different forms of use of the soil, it creates different head offices that they exercise pressures differentiated on the fragment and, consequently, on the operation of the fundamental processes of the ecosystem that represents it. Thus, in the sense of understanding the state of functional conservation of fragments forest remainders of the Atlantic forest, in the extent of the Environmental Protection Area of Petrópolis - Rio de Janeiro, which interferes in the Mosaic of Units of Conservation of the Fluminense Central Atlantic forest and, in a larger scale still, in the Ecological Corridor of the Serra do Mar, in the present study the stock of organic matter of surface of four forest fragments in summer of 2008 and summer of 2009 are analyzed comparatively.
