The horizontal predominately blue and muted gray fabric artwork includes shiny circles, squares with horizons, and groups of parallel lines that float through the space of the artwork.

This fabric artwork contains a large multi-color V shape with a pink ribbon floating across and behind. A shiny pink round shape floats behind the V shape and three square frames, two in the foreground and one in the background, create depth.

The red horizontal fabric artwork includes several vertical parallel lines with a ribbon floating behind to create depth. Lines and textures reminiscent of moss hanging from tree branches fill the left and lower portions of the work.

The artwork consists of twelve panels in varying hues of pinks, blues, browns with some angular textured lines resembling furrows and some blue lines resembling water run through and across the panels.

This report discusses the Ecological Effects Assessment of Climatic changes in Venezuela Workshop, organized by the PAN-EARTH Project and the Centre for Ecology of the Venezuelan Institute for Scientific Research (IVIC). The main objective was the evaluation of the effects of climate changes on the main ecosystems in Venezuela using ecological models.

This is the activity report for the PAN-EARTH Project Case Study Venezuela from October 1988 to March 1990.
