Veena Lakhumalani

Veena has been working as a freelance consultant since January 2009 after a career spanning 30 years with the British Council in India and 5 years with its office in Ukraine. From the late 1980s and early 1990s, she led their programmes in Health and Social Development while in Kolkata and then was their HIV and Human Rights Adviser in Ukraine where she was invited to develop the organisation’s profile in these themes.

She initiated programmes for the British Council and the British Government on prevention of HIV and AIDS amongst Sex Workers in West Bengal, Disabilities, Violence Against Women, Child Protection and particularly child sexual abuse, Trafficking of women and children, Adolescent Reproductive and Sexual Health, amongst other social issues. During the implementation of the HIV and AIDS programme, she established herself as an international consultant as well, undertaking assignments for UN agencies (WHO, UNAIDS, UNICEF, UNDP)  in Eastern Europe first to undertake KABP studies and then as a trainer for both government agencies and NGOs who intended to work with vulnerable populations on HIV prevention.

Her recent assignments include evaluation of three programmes funded by the AzimPremji Philanthropic Initiatives, one each on Adolescent Reproductive and Sexual Health, Trafficking and more recently Prevention of Domestic Violence.

Experience showed her that most of the issues cut across all socio-economic sections of society.  Silence, denial, shame and stigma are common factors too and therefore most cases are not reported, thus denying survivors emotional and legal justice.
