EXTREME changes in the weather pose yet another threat to farmers in the wake of the impending rice crisis. This was the warning raised by experts in a recently held conference by the East Asia Rice Working Group (EARWG).
Philippine Atmospheric, Geophysical, Astronomical Services Administration (PAGASA) climate data chief Lourdes Tibig explained that climate change — global warming in particular — increases the risk of crop damage. This, she said, is one of the major causes of low productivity in agriculture.
Climate change directly results in the higher incidence of flood, drought, and rising temperature, which can later on cause pest infestation. Changes in the weather, Tibig also said, affect water availability and soil fertility, which are both essential in rice production.
According to Dr. Anni Mitin of the Southeast Asian Council for Food Security and Fair Trade (Seacon), decline in crop yield creates a domino effect, which, in the long run, brings more and more people at risk of hunger and food insecurity.

Mitin explained that low harvests reduce the marginal growth domestic product from the agriculture sector, which then causes fluctuations in world market prices and changes in trade systems.
Impacts across Asia
EARWG, a network of farmer and nongovernmental organizations, presented various examples of how the impacts of climate change are being felt by farmers across Asia.
In the Philippines, the drought that hit Central Luzon, the country’s “rice bowl,” along with Cagayan Valley and the Ilocos Region last July, forced many farmers to plant corn, vegetables, and other dry-season crops instead of rice.Also, rice fields of farmers in the village of Sepaka in Mindanao have turned black and dried up because of the infestation of black rice bugs. Mindanao has been experiencing unpredictable weather, occurrences of both droughts and flash flooding, which cause regular pest infestation.
Farmers in Munshiganj, a small village in the southwestern part of Bangladesh 90 kilometers from the coast, have shifted from rice to prawn farming. The gradual increase in sea level has brought saltwater from the Bay of Bengal into the lowlands. Rice and vegetable crops failed to grow because of the seawater.
In the Isaan region in Thailand, the high salinity of rain-fed rice fields has depleted the country’s annual crop yield.
In 2006, China suffered one of its worst droughts in the past 50 years where water levels and lakes, rivers, and reservoirs dropped to historic lows. Rice-growing provinces in the country are now experimenting with “aerobic rice,” which is bred to require significantly less water than ordinary lowland rice.
Meanwhile, the prolonged cold spell in some districts in Hai Duong, Vietnam has affected crop production severely that it cost many farmers their livelihood.
Coping with climate change
Global warming arises when atmospheric greenhouse gases such as carbon dioxide, methane, and nitrous oxide trap the sun’s radiation near the Earth’s surface thus making it warm. These greenhouse gases are induced in the atmosphere by natural and human-generated means.
Developing nations, such as the Philippines, contribute far less greenhouse gas emissions than developed countries but they suffer most of the impacts. In the face of global warming, adaptation is key, stressed National Anti-Poverty Commission (NAPC) consultant Dr. Roger Concepcion.
Concepcion, a former director of the Bureau of Soils and Water Management (BSWM), said that since our country is surrounded by water, effective irrigation systems should be set up to help alleviate climate change-related production problems.
“Strategic farming can also be helpful,” he said. “If there’s a typhoon in Luzon, then focus on Mindanao.”
For Dr. Suryo Wiyono of Bogor Agricultural University in Indonesia, an effective adaptation technology is needed. “Along with water-efficient practices and microbe technology, this would include optimizing planting dates to cope with drought and flood and planting rice varieties with specific characters (i.e., drought, heat and pest resistant).”
Concepcion also proposed the use of hybrid seeds to increase rice production. Hybrid rice should fill the gap, he said, counseling though that there should be a compromise between hybrid and organic farming.
Jessica Reyes-Cantos of the Rice Watch and Action Network agreed, saying that while the use of hybrid seeds yields greater production, it should only be a short-term measure.
“The use of hybrid seeds has a greater demand for chemical fertilizers that destroy lands and water resources,” she added.
In the Philippines, chemical farming is a major contributor of greenhouse gas emissions. The groups stressed that an effective way to go is “(to become) organic.”
Tibig also said that the government should push for techniques that help increase crop production in an environment-friendly manner.
While there is no single strategy to adapt to climate change, the groups at the very least are urging farmer participation because they know more about their farms than scientists or institutions do. They also stressed that farming is a social responsibility and by upscaling sustainable agriculture, finding the balance to ensure household surplus while sustaining the national rice stock for public consumption can be achieved.
They likewise encouraged policy reviews, the country’s involvement in global trade agreements, in particular, and mainstreaming the impact of climate change by integrating disaster preparedness, climate risks mapping, and other “climate proofing” measures.

alam na alam yan ng department of agriculture itong climate change…yun kung magigising sila agad ng mas maaga…sarap matulog eh lalo na pag-busog na busog.
highly industrialized countries know also about this worsening climate change but they refused to do something about it either. these countries, because of their industries are the worst pollutants. profit-driven economy put aside environment issues, if adopting safer methods of doing business would impact the profit ledger.
The rice crisis we have today is a result of both internal and external factors. First, countries like China and and India have increased their demands for rice. Climate change plays a significant role in food production. Natural calamity like typhoon and flood could cause an abnormal increase in the demands for rice in the world market. This could lead to inflation. In economics this is called law of supply and demand. The rice crisis can also be attributed to over-population. When we have limited resources and the demand is significantly increasing, the country’s rice production cannot supply the demand for rice which would later prompt the government to import rice from other countries.
The demand to bio-fuel has caused farmers to shift from planting rice to plant crops that is less costly and could be use as sources of ethanol. Some lands use for planting “palay” has already been converted to housing projects. Add to this, Filipino farmers are not getting adequate support from the National Government to encourage them to plant “palay.” Many dams that has been used before to irrigate fields of “palay” remained idle for several years now. A lot of farmers do not have access to high yielding seeds.
you got it right nbernabe. farmers have been ignored and set aside…for a very long time. the govt always opt to importations…and not on improvements. wasted ideas. a thing in the past and still toady.
Humans in all our splendor are nothing more than a carbon based virus infecting our earthly host. As with all such organisms, when the host finally dies,… so will the virus. The host is dying as a result of our copious numbers. Longer life can only ensure all of our deaths all at once..

Very interesting point of view. That human is nothing but carbon and despite its mitochondrial DNA splendor is nothing but a virus that will eventually consume its host, mother-earth.
But floods, hurricane, typhoon, brush fires, volcanic eruptions, earthquakes, and plagues had been with us thousand of years before we invented the first non-degradable plastic and the first car that gave us carbon monoxide, and before we process freon gas in commercial quantities and released them with impunity to the atmosphere that depleted our ozone layer.
It is a case of the host consuming the virus, as a matter of self-preservation. Mother-earth, may not like humans after all, the way we behave and conduct ourselves and therefore she would like to get rid of us and make the earth free from humans. She started getting rid of humans thousand of years before even before we started getting rid of ourselves by wars and wasteful living.
The depletion of our natural resources has an indirect effect to the rice crisis we have today. Mans abuse to its environment has pave the way to host of problems we have been experiencing today. These problems need not to be mentioned as it is pretty much conceivable.
