Goals & Objectives

The project aims to test a modified technique of restoring the degraded lands using Dalbergia cochinchinensis, which involves a combination of the cluster planting and Miyawaki method, and the use of coconut husks as a water-retaining agent, overall to find out an effective alternate planting method in rehabilitating degraded lands. The objectives of the project are to:

  1. Evaluate the cost effectiveness of cluster planting combined with the Miyawaki method in rehabilitating degraded lands;
  2. Determine the survival rate of test species (Dalbergia cochinchinensis) planted together with other species in a cluster using the Miyawaki method; and
  3. Demonstrate the beneficial effectiveness of local materials (coconut husks) as a water retaining agent on the survival of seedlings.

Main Activities

  • Preparation and Establishment of Site Layout
    • Production and purchase of seedlings.
    • Layout and establishment of experimental plots
    • Sampling of weeds
  • Maintenance and Monitoring of Research Plots
    • Maintenance weeding of experimental plots.
    • Recording of the costs of establishing each plot including the cost of seedlings with photographs taken for documentation.
    • Monitoring and measurements of survival and growth data of the climax, fruit trees, and pioneer species collected from established plots.
  • Analysis of Data
    • Measurement of the frequency of weeding cost of site preparation and planting and maintenance of three plots where they will be calculated and compared.
    • A comparative analysis on the survival and growth rate of each species and each treatment will be done through using Analysis of Variance. 
    • Recording of the growth of weeds and the frequency of weeding will also be conducted.

Expected Outputs

  • A statistical analysis comparing the growth of the plants in Treatments 1, 2, and 3.
  • A comparative cost-efficiency of the three treatments.
  • Policy recommendations on the potential of the Miyawaki method.
