Dynamique spatiale et temporelle de la production primaire de l'estuaire de la Seine
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Morelle, Jérôme.
The estuaries play an important ecological role and are the site of many human activities because of their strategic position at the interface between continental and marine waters. Seine estuary is characteristic of large anthropized estuaries. Long-term management requires better knowledge of the spatial and temporal dynamics of the estuarine food webs. Phytoplankton and microphytobenthos are the main contributor of primary production (PP) in these ecosystems and are at the basis of trophic food webs. These compartments are often reduced to the chlorophyll concentration and their productivity has never been measured along the Seine estuary. The objective of this study was to estimate the PP of these compartments along the salinity gradient. In order to...

Inhibition of microphytobenthic photosynthesis by the herbicides atrazine and diuron
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Legrand, Helene; Herlory, Olivier; Guarini, Jean-marc; Blanchard, Gerard; Richard, Pierre.
Atrazine and diuron are two herbicides present in sediments of the intertidal mudflats in the Pertuis Charentais (Atlantic coast, France). They may negatively affect photosynthesis processes in microphytobenthos, the most productive primary producer in these environments. The impact of these herbicides on benthic diatoms was investigated using PAM fluorimetry on natural microalgal communities, once extracted from sediment, by following the variations of the effective quantum yield of PSII (Phi(PSII)) during exposure to atrazine and diuron concentrations in a range 0.1 mu g L-1 (.) 10 mg L-1. No significant effect was noticed for 0.1 mu g L-1 concentrations, but progressive reduction in photosynthetic efficiency, always occurring within 15 min, was...

Assessing the Comparative Advantage of Albanian Olive Oil Production
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mane-Kapaj,   Ana; Kapaj,   Ilir; Chan-Halbrendt,   Catherine; Totojani,   Orkida.
The main objective of this study is to evaluate the comparative advantage of olive oil production in Albania using Policy Analysis Matrix (PAM) method. The result indicates that olive oil production in Albania is profitable for the producers. Whereas the DRC ratio equals to 2.2, meaning that olive oil production in Albania does not have a comparative advantage for the given situation of production, prices and technology. This means that while it is profitable for private producers to manufacture olive oil for the domestic market, it does not have a comparative advantage with other EU countries. In order for Albania to develop an olive oil industry comparable to neighboring countries with similar climatic and soil conditions, the country will need to...

Assessing the Competitiveness of Indian Cotton Production: A Policy Analysis Matrix Approach
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mohanty,   Samarendu; Fang,   Cheng; Chaudhary,   Jagadanand.
This paper uses a modified policy analysis matrix (PAM) approach to assess the efficiency of cotton production in five major producing states in India. The results indicate that cotton is not efficiently produced in the second largest cotton producing state in the country. Without government interventions, it is likely that acreage will move away from cotton to more profitable crops such as sugarcane and groundnut in this state. In addition, it is also concluded that cotton is not the most efficiently produced crop in the other four states; however, there is at least one crop in each state which is less efficiently produced than cotton. These findings suggest that Indian policies directed at maintaining the availability of cheap cotton for the handloom and...

Separação sólido-líquido em efluentes da suinocultura
Provedor de dados: Revista Brasileira de Engenharia Agrícola e Ambiental
Autores: Kunz,Airton; Steinmetz,Ricardo L. R.; Bortoli,Marcelo.
A produção de suínos vem aumentando muito no Brasil e a contribuição da suinocultura industrial, que se baseia nos Sistemas de Produção de Animais Confinados (SPACs), tem sido cada vez mais representativa. Na região Oeste de Santa Catarina o crescente aumento da densidade de animais está associado a um passivo ambiental de grandes proporções, principalmente em virtude dos efluentes da produção dos suínos possuírem uma matriz com altas concentrações de matéria orgânica e nutrientes. São inúmeras as alternativas de processos através dos quais se pode realizar o tratamento dos dejetos de suínos: físicos, físico-químicos e biológicos; esses processos podem ser empregados de forma conjunta e sequencial. Neste trabalho se estudou um processo de separação...
