Forest destruction in populous tropical watersheds is mainly caused by agricultural expansion, and results in land degradation, increased habitat loss, and impoverished inhabitants. Alternately, adopting tree-dominated agriculture or forest gardens (FG) could reverse forest loss, increase livelihood security, and improve watershed sustainability. The Neo Synthesis Research Centre (NSRC) has rehabilitated farmers’ landholdings in degraded Sri Lankan watersheds for over 30 years.
This seminar will describe the rehabilitation of a degraded 4.9 ha landholding in the Maragala Oya watershed using the FG approach. Preliminary discussions revealed household issues, needs and available resources. Baseline surveys investigated topography, light, wind, water flows, vegetation structure, composition, and ecological functions, including fauna. This information guided rehabilitation using numerous tools, mainly analog forestry. More than 5,000 plants in diverse species were established between 1999-2004 to: serve household needs, recreate habitat, increase shade, soil fertility and recharge groundwater.
Project successes motivated other watershed farmers towards land rehabilitation. This study has had positive implications for watershed rehabilitation in tropical countries challenged by forest loss.
Dr Kamal (Kamy) Melvani has a multidisciplinary PhD on the social, ecological, financial and nutrition values of forest gardens in Sri Lanka, and an interdisciplinary MSc on the bioremediation of nitrates in groundwater. She is skilled in multiple restoration techniques including regenerative agriculture, conservation forestry, analog forestry, riparian forestry and bioremediation. Dr Melvani has designed and implemented 27 projects for the NSRC in Sri Lanka that restored watersheds, developed alternative livelihood initiatives for local communities, and developed multisectoral partnerships which increased ecosystem goods and services in a climate variable scenario.
She is a research adjunct at CDU, and is also engaged in the rehabilitation of degraded land for drought-adaptation, and in the biological mitigation of landslide threats in Sri Lanka.
