in fortified products, are commonly consumed in Thailand. The UN Food and Agriculture Organization (FAO) estimates that there are about 20,000 cricket farms alone in 53 of Thailand's 76 provinces. In 2018, cricket powder retails for 800-1,500 baht per kilogram, three to five times more expensive than beef. This, in spite of crickets requiring 12 times less feed, 2,000 times less water, and much less space than traditional livestock. It turns out that most Thai insect farmers are mom-and-pop outfits too small to achieve economies of scale. The market remains minuscule: The global market for beef tops US$2 trillion (66.6 trillion baht), while the market for edible insects is projected to reach only US$250 million in 2018. Sericulture Thailand's silkworm farmers cultivate both types of the domesticated silkworms that produce commercial silk: Samia ricini, commonly known as the "eri silkworm", and Bombyx mori, the "mulberry silkworm". The latter, used for most Thai silk, is by far the larger silk producer of the two. The Queen Sirikit Department of Sericulture estimates that in 2013, 71,630 small landholders raised mulberry silkworms on 39,570 rai, producing 287,771 kg of silk cocoons. Another 2,552 farmers grew mulberry silkworms on an industrial scale, producing 145,072 kg of silk on 15,520 rai of land. Eri silk, on the other hand, produces only a fraction of these quantities, grown by a small network of 600 families scattered throughout 28 provinces in north, northeast, and central Thailand. In Thailand, the Center for Excellence in Silk at Kasetsart University's Kamphaeng Saen campus plays a leading research role in sericulture research as well as providing silkworm eggs and know-how to Thai farmers. Weather Rainmaking The Thai Royal Rainmaking Project was initiated in 1995 by King Bhumibol Adulyadej. As Thai farmers faced recurring drought, he proposed a solution to the water shortage, cloud seeding. Effect of climate change It is projected that temperatures will continue to rise at a steady rate in every region of Thailand within a range of 1.2-2° Celsius. Annual rainfall is projected to decrease in the central area, but increase in the northern and northeastern regions. Volume of rainfall is projected to be around 1,400 mm per annum over the next five years. Shaobing Peng of Huazhong Agriculture University in China believes climate change is now affecting the seasonal weather in Thailand. "Global mean surface air temperature has increased by 0.5 degree Celsius in the twentieth century
