Computed from Census Data 1981 and 1991 for Kullu District.. The social structure of the population in the EDA is given in Table 3. A detail assessment of the socio-economic conditions and the resource dependence on GHNPCA has been studied as part of the WII research component in 1999.

The number of households in EDA was increased from 1364 in 1961 to 2465 in 1991 and the fuelwood consumption had also registered 78% increase during this period. Similarly, the fodder consumption had also been increased during this period. The Table 3 describes the biomass consumption in the EDA of GHNPCA. Although it is assumed that consumption of biomass (Fuelwood/Fodder) per household had not been changed substantially in the area, however due to high increase in the total no. of households the total quantities of biomass required by the households had been changed substantially. The fuel wood consumption in the area experienced a significant increase of near about 80%. In other watersheds the Tirthan experienced the highest increase of near about 85%in fodder consumption while Sainj showed the minimum increase of 64% over this period. The fuelwood consumption had been experienced almost similar trend in increase over this period.

The habitation/agriculture/orchard areas in EDA in 1961 and 1993 are shown in Fig. 3 and 4 respectively and the changes occurring are depicted in Fig. 6 and Table 4. There had been an increase of about 9 km2 in the areas under habitation/agriculture/orchard and a decline of about 4 km2 of area during the period 1961 to 1993.
