Land based industries, most significantly palm oil plantations, timber concessions and mining operations, are expanding quickly in Indonesia. With approximately 840,000 ha of forest loss per year (Margono et al 2014), Indonesia suffers the world's highest rate of deforestation. As civil society organizations (CSOs) implement forest conservation strategies and programs to respond to the issue of forest loss, there is a growing concern that they lack the ability to address gender justice, or more specifically, Gender, Environment and Development, one field of Gender and Development. 1 This weakness may undermine CSO's ability to ameliorate the gendered injustices that limit women and marginalized communities' participation in forest governance. It also limits CSO's ability to build grassroots constituencies, which are crucial for driving reform. Drawing on the Gender, Environment and Development literature, and a gender assessment of selected Indonesian environmental CSOs, this paper provides a brief overview of the major gender issues relevant to forest and land governance, and makes six recommendations to help CSOs develop more gender sensitive advocacy and programming. The paper aims to contribute to the overall objective of improving gender justice (including women's participation) in forest governance.
