The very first piece of informationn on the video is that there are 170 billion tons of wood produced annually on a global basis. This number didn't make any sense to me. I thought that's about 20-25 tons per person globally.. Then why is the world deforesting so badly? http://home.windstream.net/bsundquist1/gcia.html So if you look at these numbers you find annual terrestrial biomass is about 132 billion tons and less than 1/2 of that is woody and its all already pretty much appropriated by humans. That's why we have global deforestation happening!. GTZ should be investing in research and development of non woody biomass as a global solution to the deforesation of the worlds forests. Its simply shocking in 2010 that GTZ would put their name on something which begins with a premise that are are 170 billion tons of wood produced .....and goes on to say lets use and grow more wood and export wood from africa. I am simply amazed. Roger Samson Executive Director REAP-Canada Centennial Centre CCB13 Ste.

It shows examples from different countries where wood is sustainably produced and processed efficiently for energy purposes. The sustainable production of wood as a renewable energy source has huge potential for Africa. The afforestation of degraded landscapes, establishment of wood plantations and the sustainable management of natural forests can all serve to increase energy security, provide access to energy and reduce dependency on fossil fuels. The link on YouTube is http://www.youtube.com/watch?v=UMPaTPjvAy0 Very useful for lobbying purposes in favor of renewable wood energy. enjoy the show, Christa _______________________________________________ Stoves mailing list [email protected] http://listserv.repp.org/mailman/listinfo/stoves_listserv.repp.org http://stoves.bioenergylists.org http://info.bioenergylists.org _______________________________________________ Stoves mailing list [email protected] http://listserv.repp.org/mailman/listinfo/stoves_listserv.repp.org http://stoves.bioenergylists.org http://info.bioenergylists.org _______________________________________________ Stoves mailing list [email protected] http://listserv.repp.org/mailman/listinfo/stoves_listserv.repp.org http://stoves.bioenergylists.org http://info.bioenergylists.org
