A devastating drought hit Southeast Asia in the late 1990s and was particularly damaging in the Philippines, Indonesia, Malaysia, Thailand and Vietnam , where an estimated $20 billion of damage was caused most through lost crops. Plants withered in the heat, irrigation ditches dried up and cracked and The temperatures rose above 100°F for weeks on end.

Flooding has always been a problem but it has been exacerbated by man-made causes such as logging and slash and bun agriculture. One environmentalist with th World Watch Institute told the Los Angeles Times, “The forest that once absorbed and held huge quantities f monsoon rainfall, which could then percolate slowly into the ground, are now largely gone/ the result is much greater run-off into the rivers.”

In February 2007, Earthweek reported: Record low temperatures spread across many parts of Southeast Asia, causing crop damage as far south as the mountainous interior of the Philippines. Cambodia, Laos, Vietnam and northern Thailand experienced some of the coldest early February weather on record.The chill was caused by a Siberian high pressure area that sent the winter chill much farther south than normal. Vegetable crops in the Philippines' Benguet province were damaged when temperatures fell to 40 to 45 degrees Fahrenheit from the normal seasonal lows of 64 to 73 degrees. Provincial agriculturist Delina Juan told the French news agency that many areas of the province have been affected by the unusual weather.

Flood Risk Rampant Across Asia's Factory Zones

David Fogarty and Clare Baldwin of Reuters wrote: Global insurance companies are struggling to get a grip on their flood exposure in Asia nearly a year after one of the world's costliest disasters hit Thailand, with executives fearing an even worse event looms in the region.Some firms learnt from the Thai floods, with new defenses built to protect multi-billion dollar industrial estates in the country. Insurance premiums have also gone up, but factory construction in flood-prone areas remains rampant across Asia. Insurance executives say the industry is vulnerable to another major flood, with scientists identifying the coastal plains of southern China as one area at greatest risk.

The Thai floods hit nearly 1,000 factories feeding global supply chains - particularly in the auto sector - costing insurers an estimated $20 billion. "When I go and look at these industrial parks and ports in some of the low-lying coastal areas, I just have to stand back and think: Who's insuring these things? Who's done the risk assessment?" said Adam Switzer, a coastal scientist at the Earth Observatory in Singapore. "What I consistently see on the coasts throughout Asia is that we're still making the same sorts of mistakes." [Source: David Fogarty and Clare Baldwin, Reuter, July 22, 2012]

In the rush for development that has lifted millions out of poverty in Asia, many factories have been built along coasts, especially in river deltas. According to insurance industry executives, most construction was done without long-term historical data on floods and storms.On top of that, rising sea levels, increasing rainfall and more intense storms - together with more people and infrastructure - mean the risks have multiplied. "We should be identifying these pockets of exposure earlier," said Scott Ryrie, Asia-Pacific vice chairman for Guy Carpenter, a global insurance industry services firm.

After the Thai floods, global reinsurer Swiss Re reassessed flood risk in emerging markets. The report's No. 1 risk was China, whose vast industrial estates are at the heart of global manufacturing, making everything from iPads to brake pads. Among other Asian countries listed, Malaysia was 5, Indonesia 7 and India 10. Thailand was ninth. Munich Re and Guy Carpenter have also reviewed flood risk models, particularly for industrial parks in Asia. "A new risk awareness has to set in along the entire value chain," said Tobias Farny, Munich Re's Asia-Pacific chief executive. "The exposures present need to be defined, described and ring-fenced in order to become insurable."

El Nino

El Nino brings drought to Malaysia and Indonesia and elsewhere in the western Pacific. The devastating El Niño of 1997-98 produced a severe drought and heavy storms that more than 2,000 people and caused billions of dollars in damage to crops, infrastructure and mines in Australia and other parts of Asia. During the La Niña, Southeast Asia gets wetter.

El Niño is a periodic climate condition that occurs an average of every five years. It is strongest in the Pacific but has global ramifications. Caused when a dominate high pressure system over the Pacific collapses, it causes wind directions and ocean currents in the Pacific to change direction, throwing off prevailing winds and bringing drought to Indonesia, Southeast Asia, southern Africa and Australia, heavy rains and floods to Peru and east Africa, typhoons to Japan, stormy weather to the United States and disruptions to monsoons in India.

The name El Niño (Spanish for "the Christ Child") was coined by Peruvian fishermen in the port of Callao north of Lima in early 1970s because the warm air and water associated with change usually first appeared around Christmas. In the 20th century there were 23 El Niños and 15 La Niñas. During the 50 years period between 1950 and 200, El Nino condition existed 31 percent of the time and La Niña conditions existed 23 percent of the time.

Effects of El Niño

El Niño throws off weather patterns worldwide. In Tahiti, which normally sits under a fair weather high pressure system, waves of typhoon start rolling in. Pacific storm lash the northwest United States and drought descends on Australia, Indonesia, Southeast Asia and as far west as Southeast Africa.

El Niño brings: 1) drought to Indonesia, Southeast Asia, the Philippines and Australia; 2) heavy rains to the west coast of South America; 3) stormy wether and milder winters to western United States; 4) droughts to southern Africa; 5) fewer hurricanes to the Atlantic; 6) heavy rains to eastern Africa; and 7) disruptions to the monsoon cycle in India.

The effects can be far-reaching. During El Niño years temperatures are usually warmer in Japan, India, Alaska. The eastern United States has a warmer-than-normal winters and there are droughts in northeast Brazil. Drought-stricken areas in Indonesia, Southeast Asia, Australia, Papua New Guinea and Brazil often times experience ravaging forest fires.

During the 1997-98 El Nino, Smoke from fires caused by droughts in Indonesia reduced air visibility to less than half a mile hundreds of miles away in the Maldives. In Mongolia an unusually high temperature of 108 degrees F was recorded.

Asia Faces Threat to Crops From El Nino

In May 2012, Naveen Thukral and Lewa Pardomuan of Reuters wrote: “A return of the El Nino weather pattern may threaten food output in Asia, the world's top producer of rice and palm oil, but drier conditions in some areas could also benefit crops such as coffee and cocoa and keep global prices in check. Malaysia and Indonesia account for almost 90 percent of the world's palm oil supplies, while most of the world's rice is exported from Asia. The region also accounts for nearly 40 percent of wheat production and the bulk of natural rubber output. Thailand, the world's biggest rice exporter, is also the world's second-largest sugar exporter after Brazil. [Source: Naveen Thukral and Lewa Pardomuan, Reuters, May 10, 2012]

Coffee and cocoa could thrive this year after being hit by heavy rains last year. Vietnam and Indonesia, the world's top robusta producers, account for nearly a fifth of the world's coffee crop. Indonesia accounts for 10 percent of global cocoa output. Malaysia, the world's second-largest palm oil producer, could see lower production in 2013 if the El Nino results in poor rainfall.

Chinese authorities are keeping their fingers crossed as farmers gear up to plant the world's second-largest corn crop. In India, where farmers are banking on another near-record rice crop to keep the momentum of exports, forecasters are predicting a normal monsoon season. "An absence of El Nino in the first half of the monsoon season helps planting of summer crops and also aids initial growth stages," said S. Raghuraman, a New Delhi-based analyst.
