Research studies

Traditional agriculture forms in Cambodia were driven by an extensive management of the space (i.e. shifting agriculture in the uplands, rainfed lowland rice combined with extensive common grazing in the plains). In the past two decades, increasing demographic pressures in the uplands and the raise of new forms of family agriculture oriented by market demands, with the introduction of mechanization, have boosted the farms differentiation with a progressive exclusion of the poorest and induced tremendous degradation of natural resources.

Soil degradation and fertility depletion, and environmental externalities generated by intensive production systems, and economic pressures (higher commodities prices) threaten the main upland grains and tubers production areas in Cambodia (north, north-western, and north-east provinces). The current negative impacts on natural resources and decreasing trend of productivity call for pronounced holistic changes of the practices. Agronomic management of soil, nutrients and water at the landscape and village territory level must go hand-in-hand with the use of a large biodiversity (species and varieties) in production systems, to increase productivity (i.e., land and labor), advance sustainability, and enhance ecosystemic services.

Research studies focuses on:

    • Cropping systems design and assessment
    • Assessment of ecosystem services (soil organic C, nitrogen, labile-C fraction, microbial biomass-C, aggregation, soil functional biodiversity)
      • Land use and livelihood changes to explore intervention mechanisms adapted to each category of farming systems identified.
