Anthropogenic activities leads to deterioration of groundwater quality: A study of Mayyanad and Edamulakkal panchayats of Kollam district in Kerala
Kerala is a rain blessed state in the country, but due to its slanting topography there is significant decline in the ground water levels leading to severe water scarcity. This paper sheds light on groundwater quality issues in two panchayats of Kerala

Kerala is a rain blessed state in the country. It has highest  number of wells, when compared with other states. However due to its slanting topography there is significant decline in the ground water levels leading to severe water scarcity during summer months in most districts of the state. Further over extraction and dependence of groundwater for domestic use from the dug wells especially in rural pockets has resulted in several groundwater problems. In this backdrop the paper in  The Ecosan- An International Quarterly Journal of Environmental Science, sheds light on groundwater quality issues in two panchayats of Kerala.

Groundwater is essential for India's agricutural economy. However, there is a large variation in the groundwater resources of each region. Some regions are already over-exploited, while others can still tolerate more withdrawal. In her blog 'Waterscapes', Aditi Mukherji discusses the need for regional strategies to manage groundwater economy.

Land use changes  hydrologic system and have potentially large impacts on water resources. An assessment in an area with seasonally limited water availability and which is subject to rapid socio- economic development and population growth will provide an exemplary view on the local impacts of major recent developments in India. In this backdrop this paper analyzes past land use changes between 1989 and 2009 and their impacts on the water balance in the Mula and Mutha Rivers catchment upstream of Pune. The aim of the paper is:

  • assess the land use changes between 1989/1990 and 2009/2010
  • analyze the impacts of these changes on the long-term water balance components in the Mula and Mutha Rivers catchment upstream of the city of Pune.

Influence of anthropogenic contamination on fluoride concentration in groundwater: A study of Mulbagal town, Kolar district, Karnataka
Groundwater contamination is a serious, but relatively ignored issue in the country. This contamination occurs in either through geogenic or anthropogenic means. This paper analyses the Fluoride contamination, one such example of geogenic contamination, widely found in the Kolar district of Karnataka.

Groundwater contamination is a serious, but relatively ignored issue in the country. This contamination occurs in either through geogenic or anthropogenic means. Fluoride contamination is one such example of geogenic contamination that is widely found in the Kolar district of Karnataka. However, the fluoride levels in the town of Mulbagal are lower than those in the surroundings. Earlier, a study was conducted on the impact of pit toilets on the groundwater in the area. The present paper investigates the presence of any link between these two phenomena.View of Mulbagal Town, Kolar District, Karnataka
