Impact of Climate Change on the Philippine Rice Sector: Supply/Demand Projections and Policy

The project, which is funded by the International Rice Research Institute, focuses on the effects and impacts of climate change on rice production in the Philippines. Climate variability are subjected according to the changes in temperature, erratic rainfall pattern, more intense and extreme climatic events, El Nino incidences, and combined risks of all the mentioned climate variability.

Objectives

The specific objectives of the study are to:

  • assess the effects and impacts of climate change and climate variability on rice production in the Philippines;
  • analyse location-specific climate risks and their relations with the rice production situation by province; and
  • assess the suite of climate change adaptation measures in rice production.

Methodologies

The methodologies used in line with each objective are:

  1. Crop simulation modelling using DSSAT Rice Model; define climate scenarios as per changes in temperature, rainfall and atmospheric CO2; synthetic weather data generator; and, exploratory regression analysis to relate crop yields as function of weather variables (min and max temperature, rainfall, solar radiation, and ENSO);
  2. Compilation and documentation of available climate risks analyses due to rainfall, temperature and typhoons; GIS mapping of climate risks (by province) and relating them to rice production situation (surplus/deficit scenario);
  3. Focus group discussion, literature review, key informant interviews regarding the climate change adaptation measures and listing of Good Agricultural Practices in Rice Production and along the supply chain.
