Analysis of the UN General Assembly's Resolution on Right to Water and Sanitation
Why historic UN General Assembly Resolution declaring Water and Sanitation as a Right, was opposed and vetoed by those who strongly have been professing for human rights Posted on 30 Sep, 2010 06:47 PM

The historic UN General Assembly Resolution declaring Water and Sanitation as a Right, was passed on the 28th July 2010. 

What is surprising is the complete silence to this UN Resolution from some of the countries who have been traditional champions of human rights, in terms of celebrating it as a historic achievement in advocating a basic right to water and sanitation. Instead some of them went one step short of openly opposing and vetoing the UN Resolution and have heaped criticism on Bolivia for tabling this UN Resolution.

Protect the right to life considering the dignity of women who do not have access to a toilet
How Mumbai tackles its situation of sanitation and water: finds out Jan Jagruti Posted on 30 Sep, 2010 10:26 AM

Sanitation - a big problem in India, as half the population of our country do not have access to this facility. Mumbai is one of the biggest cities in the world and advanced in terms of its commercialization. However, sanitation is one of the most common issues neglected. Our team of women from Jan Jagruti went into the lanes of 3 areas Azad Mohala, Bharatiya Kamla Nagar, Vijay Nagar and spoke to women to understand the severity of the sanitation issue prevailing. These areas have severe problems with public health, due to improper sanitation infrastructure and insufficiency of toilet facilities, compounded by numerous issues of flooding during the monsoon season. Khaaddi, a local area/dumping ground, is widely used by local residents for urination and defecation, leading to the spread of contagious diseases. Though women use paid toilets, the issue of cleanliness and waiting in long queues are the most common problem before them. It is very insecure for them when they use open spaces for defecation.

Successful innovations in solid waste management systems: Examples from five local bodies in Tamil Nadu
This booklet illustrates examples of the implementation and impact of solid waste management innovations in five localities in Tamil Nadu Posted on 28 Sep, 2010 11:32 AM

Innovations in Solid Waste Management Systems - Tamil NaduThis booklet about the work of Exnora Green Pammal (EGP), produced by UNICEF and published by the Government of Tamil Nadu,  illustrates examples of the implementation and impact of solid waste management innovations in five localities in Tamil Nadu. The solid waste management systems in these localities are widely regarded as successes that deserve replication.This document has been produced to inspire and enable more local body authorities to emulate such successes in other parts of the country.

Improving solid waste management services in India is an urgent challenge for all levels of the government. Littering and the indiscriminate disposal of solid waste are widely practiced, polluting India's air, water, soil and inhabitants. Such pollution impedes India's efforts to achieve the Millennium Development Goals (MDG).The nation's measures to combat malaria and other diseases (MDG 6), reduce child mortality (MDG 4), and ensure environmental sustainability (MDG 7) are all hampered by the unsightly and unhygienic conditions created by the accumulation of waste.
