International Response

How effective is the International Response regarding slavery?

The United Nations has several different offices and commissions that deal with slavery, including slavery in India:
Office of the UN High Commissioner for Human Rights
UN’s STOP-Slavery
UN Protocol to Prevent, Suppress, and Punish Trafficking in Persons (signed by 177 countries including India)
The UN Security Council has multiple times condemned slavery, including slavery in India
UN Office on Drugs and Crime

There are even more non-government organizations, known as NGO’s, that deal with slavery, including slavery in India. This is a list of just some of them:
Amnesty International
Anti Slavery International
Free the Slaves
Global Alliance Against Trafficking
Hope for Justice
Know the Chain
Oxfam
Polaris
Samaritan’s Purse
Unicef
Walk Free Foundation
World Vision

The UN’s Article 4 was established in 1948, and modern-day slavery has only grown since then. Legal posturing by these international legal bodies I believe has had only a moderate effect in stemming the practice of slavery.  They encourage and lead countries to enact laws to abolish slavery and impose severe consequences, but the lack of enforcement of these laws, in India in particular, means they have very limited effectiveness. 

I believe that independent NGO’s have proven much more effective, in terms of the actual freeing of individuals, raising awareness, and putting pressure on governments and large corporations to end practices that allow slavery to continue and thrive. From housewives boycotting buying sugar in Britain in the mid nineteenth century to contemporary awareness campaigns, grassroots movements have always been most effective in seeing sustained, widespread and lasting positive changes in society.
