Past and Related Work on Climate Change in the Philippines

Previous work on climate change involved adaptations strategies to cope with the risks of changing climate.  The following are some of these measures:

1Improving farm management practices and technologies to increase adaptive capacity of the soil, crop and environment:

  • Adjusting the cropping calendar to take advantage of available soil moisture during wet periods and avoiding weather extremes during the growing season. Examples are early planting during an anticipated dry year or delaying planting date to increase minimum target yield.
  • The use of direct seeding of rice for improved water use efficiency.
  • Modification of planting distance (e.g., increasing the planting distance within rows) to increase yield levels even during a dry year.
  • Use of intercropping or multiple cropping to improve irrigation efficiency and water management at the farm level especially during dry periods.
  • Use of high yielding crops and efficient small-scale irrigation system
  • Utilization of small water impoundment to conserve water

2Crop improvement through breeding of drought-resistant or flood-tolerant varieties of staple crops, in particular, and use of new cultivars with improved response to altered climate and increasing climate extremes.

There are other past and on-going researches on climate change adaptation being done in the country, which are all focused on either modifying the management of agricultural resources to minimize risk or improving the crops or livestock to be more resilient to climate-related stress factors such as temperature increases, water logging or flooding, water stress, and salinity.  Most of these measures evaluated are already published in literatures.  However, there are also location-specific adaptation measures and good practices including indigenous ones, which are being used in some fragile ecosystems which are not fully documented but are effective.  Thus, the project also aims to document and evaluate these measures to be incorporated in the knowledge management system.
