Overview

This project aims to develop scientifically robust and actionable advice on options to sustainably manage soils in cocoa smallholdings in PNG and support the ambitions of the Cocoa Industry Strategic Plan 2016 – 2025.

Cocoa is one of the most significant cash-crops for smallholders in PNG, earning over 90 million dollars annually by producing around 36,000 tonnes, two-thirds of which are produced by smallholders. Reflecting this, the PNG Cocoa Industry Strategic Plan 2016 – 2025 (CISP) has set an ambitious target of 310,000 tonnes of annual cocoa exports by 2030. To achieve this requires approximately an 8-fold increase in production based on current outputs and is constrained by low average yields, limited opportunity for expansion and competition with other commodities for land use. However, opportunities exist to support the PNG Cocoa Industry's ambitions by tackling soil condition and capability constraints on cocoa production.

In Phase 1 of this project (SMCN/2014/048) efforts focused on establishing reliable and locally supported experimental field sites to explore the use of green waste management as a source of soil nutrients for cocoa, and capacity building in soil sampling, analysis, and interpretation.

Specifically, Phase 2 aims to develop scientifically robust and actionable advice on sustainable site-specific soil management strategies for cocoa smallholdings in PNG.

Project outcomes

  • Evaluating the efficacy of conventional and novel soil management options to improve the soil’s condition towards intensified cocoa farming,
  • Determining the regionally specific opportunities for sustainably developing and managing cocoa soils, with a particular focus on lifting the status of women smallholders,
  • Determining the implications of alternative soil management options on the development of cocoa qualities of market concern, and
  • Developing scientifically rigorous and actionable management strategies that can be promoted through public and private extension networks and adopted and adapted by cocoa smallholders.
