The seizure of people's lands and properties continues to rise as a result of the expansion of oil, gas, and mineral mining in EastJava. In the oil and gas sector, at least 63 Mining Work Areas (MWA) operate in East Java, 31 MWA with exploitation status, and 32 MWA with exploration status. Data collected through Korsup KPK (Koordinasi-Supervisi Komisi Pemberantasan Korupsi/Coordination-Supervision of Corruption Eradication Commission) for Mineral and Coal Mining show the area of mining land in East Javahas reached 551,649 hectares. It indicates a 535% increase within only 4 years. The increasing amount of land needed for mining industries will lead to the continued shrinking of people's living spaces and potentially trigger soaring poverty rates. This situation will continue to lead to the separation of many women's groups from their living spaces (means of production, land, history, social relations, and ecology), and add new social burdens as the patriarchal system continues to persist. "KAMI IBU BUMI (We Are Mother Earth)" project isdesigned to open women's participation on environmental governance in East Java. This project includes the following activities: (1) Jamboree of Women Lived-Space Fighters in order to encourage the establishmentof a network and organization in East Java; (2) Strategic meeting of women's groups with the district and provincial governments to encourage the strengthening of women's leadership capacity in ensuring good governance and development with ecologicaland gender perspectives; (3) Systematic Women's Learning Class in order to create, consolidate and disseminate knowledge between women's groups (community), NGOs and academics; and (4) Making Documentary Film on Women and Mining in East Java to show women's position, role and relationship to their lived-space and their struggle against mining industries expansion.
