Advisory system for planting Eucalyptus camaldulensis on rice bunds in salt-affected areas. (Thailand)

Description

The Thai government promotes planting of Eucalyptus camaldulensis on rice bunds to lower the saline groundwater level and prevent the spread of salt in soils - through cooperation of farmers, land owners, Siam Forestry Co., Ltd., Subdistrict Administration Organization, Land Development Department, and with specialists/ technical advisors.

The Ministry of Agriculture and Cooperatives through the Land Development Department (LDD) has initiated a project on planting salt-tolerant perennial trees on salt-affected land in the Northeast of Thailand. Thus, this project, which began in 1996 facilitated planting Eucalyptus camaldulensis on rice bunds. The main objective of the approach is to encourage and support the land users to plant Eucalyptus camaldulensis on rice bunds in salt-affected land with shallow saline groundwater. The target of planting is 1,000 rai/yr (1 ha = 6.25 rai).

The activities started with public meetings under the local administration, identifying salt-affected areas by SLM specialists and preparing soil salinity maps; establishing demonstration plots by SLM specialists and farmers, on farmers' land, as learning centers and communicating. The local administration called farmers’ meetings to prepare detailed work plans and discussion of strengths, weaknesses, opportunities, and threats of planting eucalyptus. The methods used were questionnaires and interviewing the stakeholders for their willingness to take part and cooperate with LDD SLM specialists, researchers, and experts. The LDD has provided funding for land preparation and planting cost while corporates such as Siam Forestry Co., Ltd. purchase eucalyptus poles through a contract. The Bank for Agriculture and Agricultural Cooperatives provides loans to land users.

There are three phases: the preparation phase which was seedling preparation, site selection for establishment of a demonstration plot, rice bund preparation, and establishing a demonstration plot of 200 rai at Ban Kham Riang, Muang Pia Sub-district, Banphai District, Khon Kaen Province. The coordination phase included joint meetings between farmers and researchers, joint monitoring, evaluation and follow-up with land users, and site visits to the demonstration plot. Then planting and tree establishment on farmers’ land in the salt-affected area – those farmers who were convinced by the results of the demonstration plots, Those farmers were then supported by the project on Planting Salt-Tolerant Perennial Trees on Saline Soils in the Northeast of Thailand. A market was established for the purchase of logs. There was joint monitoring & evaluation and follow up.

Results from interviews show that land users favor this project and the spread of eucalyptus planting by themselves - due to the perceived decrease in salination as well as higher income from better rice production, plus additional income from selling poles. However, there are some negative effects of fallen eucalyptus leaves (some farmers believe eucalyptus produces organic compounds detrimental to rice yield through “allelopathy”) and there was shading of the rice crop. But in some site visits there were no effects found. Furthermore, the favorable microclimate is cooler, local earth worms which used to be absent now returning, resulting in better soil properties. However, more birds and rats dwelling in this better environment became a disadvantage because they damaged the rice yield. Nevertheless, as there are more advantages than disadvantages, farmers still adopt this technology. It has been found that more than 10,000 rai (1,600 ha) with shallow saline groundwater of the salt-affected land were planted with eucalyptus trees on rice bunds in the low-lying salt-affected discharge area.

Author: Stakeholders concerned
Decision-making on the selection of SLM Technology

Decisions were taken by

  • land users alone (self-initiative)
  • mainly land users, supported by SLM specialists
  • all relevant actors, as part of a participatory approach

  • SLM specialists alone
  • politicians/ leaders

Decisions were made based on

  • evaluation of well-documented SLM knowledge (evidence-based decision-making)
  • research findings
  • personal experience and opinions (undocumented)

Impacts of the Approach
No
Yes, little
Yes, moderately
Yes, greatly
Did the Approach empower local land users, improve stakeholder participation?

Strengthening relationship between local government administration and land users.

Did the Approach enable evidence-based decision-making?

Establish learning center for information to farmers for technology adoption.

Main motivation of land users to implement SLM
  • increased production
  • increased profit(ability), improved cost-benefit-ratio
  • reduced land degradation
  • reduced risk of disasters
  • reduced workload
  • payments/ subsidies
  • rules and regulations (fines)/ enforcement
  • prestige, social pressure/ social cohesion
  • affiliation to movement/ project/ group/ networks
  • environmental consciousness
  • customs and beliefs, morals
  • enhanced SLM knowledge and skills
  • aesthetic improvement
  • conflict mitigation
Sustainability of Approach activities
Can the land users sustain what hat been implemented through the Approach (without external support)?
  • no
  • yes
  • uncertain

Farmers have a better understanding and positive attitude of planting eucalyptus, since they obtain additional income from selling eucalyptus logs.

Conclusions and lessons learnt

Strengths: land user's view
  • Community soil doctor volunteer and community leader are the coordinators in the area.
  • Farmers access to markets and sources of Eucalyptus seedlings easily.
  • LDD officers have continually surveyed and followed up in the area.
  • Distribute seedlings free of charge.
  • Good marketing for the purchase and sale in the area.
Strengths: compiler’s or other key resource person’s view
  • A supported technique created to develop technology to suit landscape in the Northeast area.
  • Planting eucalyptus knowledge was provided regularly by the Land Development Department and Siam Forestry Co., Ltd.
  • Siam Forestry Co., Ltd. develop marketing covering the Northeast region.
  • A demonstration plot established in the area.
Weaknesses/ disadvantages/ risks: land user's viewhow to overcome
  • The LDD officers do not visit when the land users need help. The officers need to contact the land users and give advice more often.
  • More birds and rats attack rice seeds in the field. Set up crow scaring; some farmers catch birds and rats to eat.
Weaknesses/ disadvantages/ risks: compiler’s or other key resource person’s viewhow to overcome
  • Farmers planted closer spacing of 1 m, expecting to get more wood product, regardless of the adverse effect on rice. Clearly illustrate the adverse effect of closer spacing of plants.
  • Income from logs is considered too low. Changing crops such as olives, figs, dates, pomegranate, etc.
