Trees and forests play important roles in reducing landslide risk through various mechanisms. Tree roots reinforce soil layers, anchor the soil to bedrock and form buttresses against soil movement. Trees also reduce landslide risk by lowering soil moisture levels – interception, evaporation and transpiration are the primary mechanisms. These mechanisms, and others, also make trees valuable in land reclamation following landslides.

With 48% forest cover, the Greater Mekong Subregion still has large areas of forest remaining. The area of primary forest is, however, low and falling, while large tracts of forest are highly degraded and forest planting rates remain low in most countries. Reinvestment in forests is necessary to maintain wood and timber production, support biodiversity conservation and climate change mitigation, revitalise rural economies and protect against natural hazards and the impacts of climatic alterations. For a greener future, investment in forestry is essential.

Addressing the role of women in forestry is central to sustainable resource management and rural livelihood improvement. Improving women’s access to forest resources and effectively including them in decision making leads to greater investment in children’s welfare and has positive effects on economic growth and sustainable resource management. Opportunities for women to adopt new roles and improve their livelihoods are increasing but gender imbalances still threaten sustainable development.
