GREEN PRODUCTIVITY: AN APPROACH FOR SUSTAINABLE DEVELOPMENT OF AGRO-FORESTRY IN SRI LANKA.

Abstract

The agricultural and forest resources in Sri Lanka are diminishing while thepopulation is still growing. Hence, designing of resource-efficient agroforestrysystems has considerable potential not only to improve forest andagricultural production but also to enhance and maintain overall productivityof sustainable small farm units. The different types of agro forestry systemsin the country are highly diverse and complex in characters and functions.However, the productivity of agro-forestry system and the role inenvironmental conservation are lower than their potential due to lack ofproper management practices. Green Productivity (GP) approach emphasizesthe sustainable development of agro-forestry systems enhancing productivityand using resources efficiently while protecting the environment.

The paper attempts to discuss the concept, methodology, principle stage,implementation strategies and impact assessment of GP approach with theview of sustainable development of agro-forestry systems in Sri Lanka. TheGP concept emphasizes environmentally sound technology transfer to keepagro forestry systems competitive; environmental regulations to extendfarmers responsibility; and cleaner production enhancing productivity andenvironmental performance of the agro-forestry systems. The methodologyof GP would consist of problem-solving steps, selecting tools, techniques andtechnologies useful for solving problems in agro forestry and application ofsocio-economic and environmental principles and values for agro-forestryimprovements. The six principle stages of GP are described in terms ofgetting started to gain base-line information and identify problems in agroforestrysystems: generation and evaluation of GP options to meet theobjectives and targets of the agro-forestry system: implementation of GPoptions involving performance and the targets being achieved: and sustainingGP through corrective options to achieve objectives and targets of thesustainable agro forestry systems.
