Our results in
Nan province
The start of our mission to plant, monitor, and create lasting change
Why Nan?
Nan is home to one of Thailand’s most important watersheds, contributing more than 40% of the water flowing into the Chao Phraya River. Yet over the past decade,
more than 1 million rai (160,000 hectares) of forest areas have been converted into monoculture farmland.
The “Maize Capital”
Demand from the animal feed market has driven many farmers in Nan to grow maize and other monoculture crops, with buyers purchasing their produce directly from farms.
A vulnerable farming system
Although monoculture farming provides short-term income, it has lasting negative impact, including soil degradation. Farmers also have to rely on chemicals and the burning of agricultural residues due to farming on steep slopes, affecting both the environment and health.
Trapped in a cycle of debt
Maize and other monoculture crops generate limited profits, while debt leaves many farmers without the capital needed to transition to sustainable agriculture.
Growing risks in the changing climate
As forests are lost and soils erode, floods, forest fires, and haze become more severe amid the changing climate.
Impact on the environment
Bringing life back to the ecosystems

Regenerative farms with diverse sources of income
Farmers receive funding to plant perennial trees that help restore the soil, enabling them to diversify into crops such as fruit trees and beans and generate consistent income.
Stingless beekeeping
Stingless bees help pollinate crops, increasing yields, while producing high-value honey with medicinal properties. They also provide farmers with an incentive to reduce burning and chemical use, as the bees can only live in areas free from fire and harmful chemicals.
Goat farming
Farmers raise and breed goats for sale, with female goats giving birth an average of twice a year. Goats can also feed on agricultural residues and a wide variety of plants, helping reduce the need for burning.
Creating opportunities through a community-based enterprise
Tree planting leads to community business development. Working with local experts, communities develop products linked to restoring the Nan watershed ecosystem, such as stingless bee honey soap.

The Trees4All Community-based Enterprise
brings together farmers in Santisuk district, Nan Province.
Members plant trees together and develop community businesses, including seedling nurseries, stingless beekeeping, goat farming, related products, and hosting study visits. With support and capacity development from the Trees4All project team, the group was formally registered as a community enterprise in 2023.
