Résumé
Many of the world’s ecosystem have undergone significant degradation with
negative impact on biological diversity and human livelihood. Thus, timely and
effective interventions for ecological restoration have to be made to reverse this
degradation process, as it is necessary to maintain the status of ecosystem. The
phenomenon of ecological restoration has also been observed in Chaksu Block,
Jaipur district, Rajasthan, which was hit by flood in 1981 resulted into massive
erosion of soil leaving the land unproductive which was later taken up for
restoration by Forest Department with the local people. Moreover, indigenous
cultural and ritual practices of the local people in sacred groves also provided a tool
for conserving forest ecosystem. The joint efforts of the Government and Forest
department resulted in increased green cover and improved soil quality. In addition
soil fertility is also influenced by the presence of micro-organisms. By assessing the
characteristic of soil micro-organism community, we can predict the status of the
microbial ecosystem and in turn the quality of soil and the progress of restoration
after degradation. In the present study we planned to analyze various physicochemical parameters of soils along with their microbial analysis. Soil samples were
collected from restored (Experimental site) and unrestored (Control site) area of
Thooniram Laxmanpura village of Chaksu Block. The soil parameters like Water
Holing Capacity, Moisture Content, texture, pH, Electrical Conductivity, Organic
Carbon, Organic Matter, Exchangeable Calcium and Magnesium, Available Sodium
and Potassium, available Phosphorous and Total Nitrogen were analysed. The
statistical comparison was done using the student t-test and results was found to be
significant between the restored and unrestored soil samples. The results of the
present study gives us an idea about the improved fertility of soil in the restored area
which proves that the restoration measures adopted by the community people and
Government were quiet effective. Hence such kind of practices should also be
implemented to other villages.
Mots clés : Land degradation, ecological restoration, sacred groves, green cover, soil physico-chemical parameters, microbial analysis and soil quality.
