Botanical pesticides can be recommended as an ecochemical and sustainable strategy in the management of agricultural pests. Because of their biodegradable nature, systemicity after application, capacity to alter the
behaviour of target pests and favourable safety profile, it is hoped that plant-based pesticides play a significant role in achieving evergreen revolution.
The Ousteri Lake is the most important fresh-water lake of Puducherry region. It is also one of the most important wetlands of Asia. The lake is situated near Oussudu village and is part of both Tamil Nadu and Puducherry.

Climate change is a term that almost every educated person uses today. Hot days, as summer approaches, are quickly interpreted as tangible signs of global warming. Sudden, unanticipated events like torrential downpours
Since the first report on the serodiagnosis of HIV-1 infection in 1987, several laboratories from India have contributed significantly to the knowledge of HIV/AIDS over the years. These reports span a wide range
Sacred groves are (small or large) patches of vegetation of varying sizes, conserved on the basis of the religious beliefs of the community. In India 13,720 sacred groves have been identified from 19 states and named differently in various parts of India as Law lyngdhoh in Meghalaya, Kovil Kadu in Kanyakumari, Dev Bhumi in Uttarakhand, etc.
The comparative assessment of morphologic runoff and annual silt load from micro-watersheds can help in establishing relationships between these parameters with objectives of controlling runoff, conservation of soil, reduction of reservoir silt load and enhanced groundwater resources in the micro-watersheds.
The conservation of wildlife species in the Indian sub-continent has often been influenced by their aesthetic, socio-cultural and religious importance, prior to their ecological role. This system over the years has certainly been biased towards the terrestrial ecosystems affecting
Hydrogeological and geomorphological parameters have been quantitatively correlated with groundwater availability. Weathered rock thickness has the highest control on availability of groundwater followed by lineament density whereas drainage density is seen to have minimum influence. A poor correlation is noticed between borewell depth and yield.
