Lichens an mutualistic amalgamation of an fungi (mycobiont) and a green algae (photobiont) or blue green algae (cyanobiont) are some of the most efficient indicators of changing environmental conditions. Lichen habitat (corticolous-on bark; saxicolouson rock and terricolous- on soil) and growth form (crustose, foliose, leprose, squamulose fruticose and dimorphic) subsets are used worldwide for assessment of ecosystem health and effect of anthropogenic activities. Ordination statistics, a multivariate exploratory data analysis technique has been found to be very effective in of lichen interpretation community composition in terms of their responses to environmental gradients. Various variants of ordination e.g. Principal component analysis (PCA) , Correspondence analysis (CA), Canonical correspondence analysis (CCA) and Detrended canonical analysis (DCA), which maps lichen spices/sites according to variance in the data set" with maximum variance in first two or three axis, when are correlated (two tailed) with various habitat or pollution indicators (parameters), results is statistically significant correlations. Such approach in lichen based biomonitoring studies have validated the pOSItIOn lichens as efficient bioindicators of changing planets which are now used extensively in interpreting effect of glO,bal warming, pollution, change in land use pattern and various other anthropogenic pressures on habitats. 1111111 © World Congress for Man and Nature, India 427 Late Wangari Maathai Wangari Muta Mary Jo Maathai was a Kenyan environmental and political activist. She was educated in the United States at Mount St. Scholastica and the University of Pittsburgh, as well as the University of Nairobi in Kenya. In the 1970s, Maathai founded the Green Belt Movement, an environmental non-governmental organization focused on the planting of trees, environmental conservation, and women's rights. In 1986, she was awarded the Right-Livelihood Award, and in 2004, she became the first African woman to receive the Nobel Peace Prize for "her contribution to sustainable development, democracy and peace." Maathai was an elected member of Parliament and served as assistant minister for Environment and Natural Resources in the government of President Mwai Kibaki between January 2003 and November 2005. In 2011, Maathai died of complications from ovarian cancer. WCMANU - 2011 is giving the tribute to Wangari Maathai for devoting her whole life for serving humanity and nature.
