The article describes patterns of fuel wood collection and per capita daily consumption across seasons and altitudes in the buffer zone of Nanda Devi Biosphere Reserve, Western Himalayas. Three villages, located at different altitudes were monitored during 1994-1995 in order to identify fuel wood collection pattern during 1995-1996 to quantify fuelwood consumption patterns. Rate of fuel wood collection was found to be highest just before the onset of winter during September-October. With declining altitude, per capita daily and seasonal consumption of fuel wood also declined. Average per capita daily consumption was, however, substantially higher in the study villages when compared to other studies. At the household level there was a negative correlation between family size and per capita daily consumption of wood. Easy accessibility to fuelwood in the surrounding forests, cold climatic conditions and the lack of alternatives resources have been identified as the major factors for the higher consumption rates of fuel wood, especially in the higher altitude villages. The findings of the study have been concluded in the light of the sustainable use of wood fuel for the long-term conservation of the buffer zone forest.- Status of Natural Terrestrial Vegetation in Gujarat - a Reassessment

The paper examines the trends in the status of natural terrestrial vegetation in Gujarat under three major categories viz. forests, scrubs and grasslands. Information on various aspects of types, extent and changes in the above categories were collected from three major sources including the published and unpublished reports of Gujarat State Forest Department, biennial reports of Forest Survey of India and vegetation map of French Institute of Pondicherry. Satellite remote sensing data is also used to assess the vegetation quality using commonly used vegetation index i.e. Normalized Difference Vegetation Index (NDVI). The actual forest cover is 66.66% of that reported and therefore the forest cover of the State after applying corrections will be about 6.4% of total geographical area. The study recorded a decline of about 5,800 km2 area under dense category in last three decades. Adequacy of reporting categories in discerning trends in vegetal cover of Gujarat and the disparities between administrative data on forest and land-use on one hand and the FSI assessment on the other have been examined. Digital imagery analysis has been undertaken, in an illustrative sense, to show that, without too much effort, it is possible to significantly improve the understanding of vegetation status. This exercise clearly shows that improvements in the Forest Survey of India assessments will considerably help in monitoring the forest cover changes and help in identifying vegetal cover changes in arid and semi-arid regions. Based on the available data on Gujarat and its limitations, we have contemplated certain possibilities for improving the data inventory to facilitate meaningful ecological monitoring.- Livestock Population Vis-a-vis Common Property Land Resources : Trends from Gujarat

This paper discusses the trends of livestock population between 1972 and 1992 and the area under Common Property Land Resources (CPLR) between 1970-71 and 1995-96 in the state of Gujarat. It has been observed that despite a decline in the livestock population during 1972-77 and 1982-87 due to droughts, there has been an overall increase of about 33.4%. Contrary to these trends, the proportion of CPLR to the total geographical area of the state declined from 27% to 18.4% between 1970 and 1995. The similar trends were reflected across the five regions of the state. Due to increase in the livestock population, there has been significant increase in the livestock density in terms of adult cattle unit (ACU) per CPLR, which increased from 2.62 ACU/ha in 1972 to 4.49 ACU/ha in 1992. The implications of the above findings have been explained in the light of trends in the livestock population and the area under CPLR in the state and across regions.- An Evaluation of Successful Reclamation of Bauxite Residue through Afforestation Activities in South India
