Vegetation structure and greenness in Central Africa from Modis multi-temporal data.
2013
African forests within the Congo Basin are generally mapped at regional scale as broad-leaved evergreen forests, with a main distinction between terra-firme and swamp forests types. At the same time, commercial forest inventories, as well as national maps, have highlighted a strong spatial heterogeneity of forest types. A detailed vegetation map generated using consistent methods is needed to inform decision makers about spatial forest organisation and theirs relationships with environmental drivers in the context of global change. We propose a multi-temporal remotely sensed data approach to characterize vegetation types using vegetation index annual profiles. The classifications identified…
Dendrolatrie della scia. Corpi arborei e semi della memoria
2021
Invisibilizzazione, disumanizzazione, dolore del trauma, naufragio: la scia si produce e si riproduce in mare, in un attraversamento in cui il Mediterraneo diviene eco dell’Atlantico e viceversa. Centrale per questo riecheggiare è la memoria. La memoria di un passato che non è mai passato, che torna a fratturare il presente e continua a riprodursi in un tempo circolare della schiavitù, inteso come futuro creato da essa (Hartman 2007). E la creazione del futuro passa per la coltivazione dei semi della memoria: semi in movimento, che creano così una trama filiforme che unisce l’Atlantico Nero al Mediterraneo Nero. Depositari del passato e base per la creazione del futuro, i semi della memoria…
Les terroirs viticoles : une méthodologie de zonage en fonction du sol
2010
Terroir is a key-concept in viticulture that is more and more widely recognized to explain variations in wine quality and wine style. Terroir refers to an area and thus possesses a geographical dimension. Hence, zoning of viticultural terroir is necessary. This paper addresses soil related aspects of terroir zoning. The first step of the zoning process is a clear identification of the objectives that are being pursued: demarcation of production areas, the adaptation of the viticultural management practices to variations in soil types or the protection of viticultural landscapes. The second step is the definition of a scale adapted to the objectives. The precision of the zoning increases wit…
