Large-scale fire: creator and destroyer of secondary forests in Western Indonesia por Dennis, R.A., Hoffmann, A., Applegate, G., Gemmingen, G. von, Kartawinata, K.

“…Large scale, catastrophic fires have become a significant and visible part of the tropical forest landscape in the past two decades with increased commercial exploitation of forests, forest conversion and increased population pressure. Secondary forests are an increasingly prominent feature of tropical landscapes and fires play a significant role in both the creation and destruction of these forests. …”

Accounting for the ecological dimension in participatory research and development: lessons learned from Indonesia and Madagascar por Laumonier, Y., Bourgeois, R., Pfund, J.L.

“…We build upon a comparison of three cases that show inverse gradients of knowledge and perceptions of the environment and human pressure on natural resources. We discuss why the ecological dimension currently lags behind in the management of tropical forest landscapes and to what extent participatory development can enhance the fit among ecological, socio-cultural, and economic systems. …”
