Para compreensão da dinâmica do espaço natural, a Geografia Física possuiu inúmeras interdisciplinaridades que a acompanham, e a caracterização geoambiental é uma delas, no propósito de reconhecimento dos elementos constituintes da paisagem. O presente trabalho foca na caracterização geoambiental do município de Milagres, município do sul cearense, e teve como metodologia, pesquisa bibliográfica e cartográfica acerca dos elementos geoambientais da área de estudo, assim como a elaboração de material cartográfico utilizando os programas ArcGis e Qgis. Partindo desse material foi realizado uma breve descrição deste município, focando fundamentalmente nas características ambientais. É essencial o estudo da área em que irá realizar pesquisas, buscando o aprofundamento dos saberes de seus aspectos geoambientais para se obter uma prévia do conhecimento do local que irá ser trabalhado.Palavras-chave: Caracterização Geoambiental; Cariri cearense; Milagres/CE. ABSTRACTFor the dynamics of the natural space, a physical geography had numerous interdisciplinarities that accompany it, and a geoenvironmental characterization is one of them, without the purpose of recognition of the constituent elements of the landscape.

Blue Carbon, which is carbon captured by marine organisms, has recently come into focus as an important factor for climate change initiatives. This carbon is stored in vegetated coastal ecosystems, specifically mangrove forests, seagrass beds and salt marshes. The recognition of the C sequestration value of vegetated coastal ecosystems provides a strong argument for their protection and restoration. Therefore, it is necessary to improve scientific understanding of the mechanisms that stock control C in these ecosystems. However, the contribution of Blue Carbon sequestration to atmospheric CO2 in shallow waters is as yet unclear, since investigations and analysis technology are ongoing. In this study, Blue Carbon sinks by Zostera marina were evaluated in artificial (Gotenba) and natural (Matsunase) Zostera beds in Ise Bay, Japan. 12-hour continuous in situ photosynthesis and oxygen consumption measurements were performed in both areas by using chambers in light and dark conditions. The production and dead amount of Zostera marina shoots were estimated by standing stock measurements every month. It is estimated that the amount of carbon storage as Blue Carbon was 237g-C/m2/year and 197g-C/m2/year in the artificial and natural Zostera marina beds, respectively. These results indicated that Zostera marina plays a role towards sinking Blue Carbon.

A study was conducted to gain insight on actual sedimentological and biological effects associated with the construction of an oil Terminal designed to receive 500 000 d.w.t. tankers. Field investigations and subsequent laboratory analyses were organized to evaluate the nature and magnitude of environmental changes on benthic macrofauna, three years after the end of the construction. Sediments were found to decrease dramatically in medium grain size in area sheltered by the newly built breakwater. Increase of percentage of silt and clays (90 % against 20 %) was observed leeward of the jetty. The benthic fauna showed significant modifications. Although the same community (Pectinaria kareni Abra alba) recolonized the bottom after the dredging of up to 30 × 106 m3 of sediments, increase in abundance occured. Biomass remained at a constant level and decrease of diversity was observed. Considering the rate of siltation, and assuming a constant siltation rate equal to the rate observed from 1975 to 1978, a simple regressive model relating biomass to mean grain size of sediments has been developped. This model allowed the prediction of biomass and production of the two principal species for the period 1978 – 1981. Continuous siltation within the harbor leads to a maximum of biomass from years after the end of the construction, followed by a decrease of standing stock. This process may be explained by the respective tolerance of the two principal species to increase silt contant and also probably by the accumulation of organic matter which may impede the development of natural populations.
