This is the real-life story of Rukmini Devi who lives in a small hut in Gaigotha Village in Wada Taluka of Palghar District in Maharashtra State. She belongs to the Warli tribe. Her husband is a marginal farmer who cultivates on two acres of land. They have two children, one daughter aged 10 years and a son aged 6 years. Both the children walk to school and back daily (located about 3 miles away). When cultivation season is over, (or if the rice crop is damaged due to heavy rains or pests) they face many hardships. A section of the crop is kept for their personal use, for the year. Tur Dal (lentil) is also grown in one small area, again for personal use. In a small backyard, they grow vegetables like chilies, cucumber, and bitter gourd (karela). During the off-season, both husband and wife go to the brick kilns (about 7 miles away) to do piece-rate work (That is, they get paid for each brick that they make). While the men earn Rs. 300 per day, the women earn Rs. 150-200. Rukmini Devi stated that they prefer to walk the 7 miles both ways because the bus fare is Rs. 35/- per head one way. They cannot afford it. |
