Institution: Madras Institute of Development Studies, Chennai

Overview: This report examines agriculture and the land market in three villages in Nagapattinam district. While agriculture is potentially vibrant, water scarcity significantly constrains production, leading to varied productivity across the landscape. Households have diversified into non-farm employment within and outside the villages due to declining agricultural returns and evolving aspirations. However, this employment is neither secure nor well-paying. Although a speculative land market has not yet emerged, it is likely to develop if both agriculture and non-farm employment remain unsustainable.

Institution: Madras Institute of Development Studies, Chennai

Overview: This report examines agriculture and the land market in three villages in Tirunelveli district. While agriculture is potentially vibrant, water scarcity significantly constrains production, leading to varied productivity across the landscape. Households have diversified into non-farm employment within and outside the villages due to declining agricultural returns and evolving aspirations. However, this employment is neither secure nor well-paying. Although a speculative land market has not yet emerged, it is likely to develop if both agriculture and non-farm employment remain unsustainable.
