  System of Rice Intensification - Sri Lanka

A rice paddy could be a flooded parcel of cultivable land used for growing semiaquatic rice. Paddy cultivation mustn't be confused with cultivation of problem rice, that is full-grown in flooded conditions with water over fifty cm (20 in) deep for a minimum of a month. Genetic proof shows that each one varieties of paddy rice, each indica and japonica, spring from a domestication of the wild rice Oryza rufipogon that initial occurred eight,200–13,500 years agone South of the Chang in contemporary China.[1] but, the domesticated indica taxon presently seems to be a product of the introgression of favorable alleles from japonica at a later date, in order that there square measure probably many events of cultivation and domestication.[2] Paddy fields square measure the everyday feature of rice farming in east, south and geographic area. Fields are often engineered into steep hillsides as terraces and adjacent to depressed or steeply slanted options like rivers or marshes. they will need a good deal of labor and materials to form, and wish giant quantities of water for irrigation. Oxen and buffalo, tailored forever in wetlands, square measure vital operating animals used extensively in rice paddy farming. 

 

During the twentieth century, paddy-field farming became the dominant kind of growing rice. Hill tribes of Thailand still cultivate dry-soil varieties referred to as upland rice.[3] rice paddy farming is practiced in Kampuchea, Bangladesh, China, Taiwan, India, Indonesia, Iran, Japan, North Korea, South Korea, Malaysia, Myanmar, Nepal, Pakistan, the Philippines, Sri Lanka, Thailand, Vietnam, and Laos, Northern Italia, the Camargue in France,[4] the Artibonite vale in Haiti, and California|state capital} vale in California. Paddy fields square measure a significant supply of region gas and are calculable to contribute within the vary of fifty to one hundred million tonnes of the gas each year.[5][6] Studies have shown that this will be considerably reduced whereas conjointly boosting crop yield by debilitating the paddies to permit the soil to aerate to interrupt gas production.[7] Studies have conjointly shown the variability in assessment of gas emission mistreatment native, regional and world factors and occupation for higher inventorisation supported small level information.

Spider

Giant Tarantula Discovered in Sri Lanka

A new kind of tarantula concerning the dimensions of your face has been found in northern Sri Lanka. Scientists found the spiders — with a leg span up to eight inches across — living in trees and also the previous doctor’s quarters of a hospital in Mankulam.

Covered in lovely, ornate markings, the spiders belong to the genus Poecilotheria, called “Pokies” for brief. These square measure the tiger spiders, associate degree arboreal cluster native to Republic of India and Sri Lanka that square measure far-famed for being colourful, fast, and venomous. As a group, the spiders square measure associated with a category of South yank tarantula that features the Goliath bird-eater, the world’s largest.

The new spider, named Poecilotheria rajaei when an area police inspector United Nations agency helped the team navigate post-civil war northern Sri Lanka, differs from similar species primarily within the markings on its legs and bottom, that bears a pink abdominal band.

“This species has enough vital variations to separate it from the opposite species,” same Peter church, editor of British people Tarantula Society‘s journal, that printed a study describing the spider in December. But, Kirk notes, categorisation determinations supported physical descriptions will provoke disagreement. “I fully would like to see desoxyribonucleic acid sampling done — on all the species of Poecilotheria,” he said.

The spider’s distinctive leg markings embody geometric patterns with daffodil-yellow and gray inlays on the primary and fourth legs. it had been 1st seen throughout a Sri Lankan arthropod survey light-emitting diode by Ranil Nanayakkara, co-founder of Sri Lanka’s multifariousness Education and analysis. In October 2009, an {area|a neighborhood} dweller conferred Nanayakkara and his team with a dead male specimen that didn’t fit far-famed Poecilotheria within the area. Before the team might begin describing the presumptive new species, they required a lot of people. Scouring the semi-evergreen, wooded space for females and juveniles needed the assistance of police inspector archangel Rajakumar Purajah, United Nations agency attended the team through areas simply getting down to endure a warfare. Eventually, the team found enough spiders — together with those concealment in an exceedingly hospital — to assemble an in depth description of the new arachnids.

“They square measure quite rare,” Nanayakkara same. “They like well-established previous trees, however thanks to deforestation the amount have dwindled and thanks to lack of appropriate environs they enter previous buildings.”

 

insects

The exact species for different orders remains not classified and documented. Walker on 1861, listed 2,007 species belongs to nine insect orders and Haly on one890 known 1,510 beetle species from Sri Lanka. However, when series several|of the many} publications from many foreign entomologists, 2 Sri Lankan entomologists, Salientia Wijesekara and D.P Wijesinghe exactly documented eleven,144 insect species belongs to thirty orders from Sri Lanka in 2003.

Hubbard and colleagues documented forty six species in eight families of order Ephemeroptera. Henneman in 2002 recorded sixty nine species so as Orthoptera. He conjointly collected few specimen of order Phasmatodea around central hills. sixty six species of order Blattaria area unit found, however not compartmentalization evidences. Few species of the order Mantodea were studies by Henry in 1931. Clear documentation of the species inside Dermaptera may be found, that was initiated by Burr (1901) and patterned (1972). inside the white ant taxon Isoptera, fifty six species recorded. In 1913, inexperienced compiled a pithy catalogue for isopterans in Sri Lanka.

Only four species of order Embiodea area unit recorded. within the order Corrodentia, 2 subfamilies studied. they're Epipsocidae and Pseudocaeciliidae. Informations of the species of the orders animal order, Neuroptera, Mecoptera, and animal order area unit only a few and additional studies area unit needed. solely the family Coniopterygidae of Neuroptera are studied in 1982.

Sri Lanka is thought to home for 794 species of Hemipterans. careful work of Sri Lankan hemipterans area unit recorded in book "Catalogue of order Hemiptera of Sri Lanka. Checklists on orders order Trichoptera and Strepsiptera area unit well documented, however recent work is required.

Australia Migration

Australia needs 250,000 new migrants a year: study

Independent modelling commissioned by the Migration Council of Australia warns regarding the risks of reducing web migration.

The migration report comes because the government releases the five-yearly Intergenerational Report (IGR) that shows that migrants area unit expected to form up a smaller share of the population in coming back decades.

The IGR provides a photograph of Australia in 2055, once the population is tipped to virtually double from twenty four million nowadays, to forty million. The modelling shows Gross Domestic Product can fall and wage growth can slow.

The government assumes web overseas migration can stay stable at 215,000 folks p.a., down from a peak of three hundred,000 in 2008-9.

Currently, web overseas migration (new migrants inbound, minus Australians exploit per year) makes up one per cent of the national population, however that's expected to decrease to zero.5 per cent by 2055 below the IGR modelling. The modelling says Australia wants 250,000 migrants a year to spice up the economy by $1.6 trillion by 2050.

But the alternate modelling from the Migration Council of Australia shows if annual migration was enhanced to 250,000 people, the economy would be boosted by $1.6 billion - an increase of $1,125 per person in Gross value.

Saree.Srilankan,Indian

In the history of Indian article of clothing the saree is copied back to the Indus depression Civilisation, that flourished throughout 2800–1800 before Christ round the western a part of the Indian landmass.[4][5][6] Cotton was initial cultivated and woven  in Indian landmass around fifth millinim before Christ.[14] Dyes used throughout this era ar still in use, notably indigo, lac, red madder and turmeric.[15] Silk was woven  around 2450 before Christ and 2000 before Christ.[16][17] The earliest illustrious depiction of the saree within the Indian landmass is that the sculpture of AN Indus depression priest carrying a drape.[4][5][6]

The saree evolved from three-piece apparel called Antariya lower garment, Uttariya veil worn over shoulder or head and Stanapatta a chestband, that finds mentioned in Sanskrit literature and Buddhist Pali literature throughout sixth century B.C.[18] this entire three-piece dress was called Poshak, generic term for costume.[19] Ancient Antariya closely resembled dothi wrap within the "fishtail" version that was saw legs, coated the legs loosely and so flowed into a protracted, ornamental pleats at front of the legs.[4][20][21] It more evolved into Bhairnivasani skirt, these days called ghagri and lehenga.[22] Uttariya was a shawl-like veil worn over shoulder or head, it evolved into what's illustrious these days called dupatta and ghoongat.[23] Like wise, Stanapatta evolved into choli by first century A.D.[24][25] Between ordinal century B.C to first century A.D, Antariya and Uttariya was integrated to create one garment called saree mentioned in Pali literature, that served the aim of 2 clothes in one-piece.[26][27]

The ancient Indo-Aryan work, Kadambari by Banabhatta and ancient Tamil poetry, like the Silappadhikaram, describes ladies in exquisite material or saree.[28][29][30][13] In ancient Asian country, though ladies wore saris that bareheaded the midriff, the Dharmasastra writers explicit  that girls ought to be dressed specified the navel would ne'er come into sight.[31][32] By that for a few time the navel exposure became a taboo and therefore the navel was hid.[33] [34][5] In ancient Indian tradition and therefore the Natya Shastra (an ancient Indian piece of writing describing ancient dance and costumes), the navel of the God is taken into account to be the supply of life and power, thence the midriff is to be left blank by the saree.[35][36] ho

 Early literature incorporates a wide vocabulary of terms for the netting utilized by ladies, like Avagunthana (oguntheti/oguṇthikā), that means cloak-veil, Uttariya that means shoulder-veil, Mukha-pata that means face-veil and Sirovas-tra that means head-veil.[37] within the Pratimānātaka, a play by Bhāsa describes in context of Avagunthana veil that "ladies is also seen with none blame (for the parties concerned) in a very spiritual session, in wedding festivities, throughout a misfortune and in a very forest". [38] an equivalent sentiment is a lot of generically expressed in later literature.[39] Śūdraka, the author of Mṛcchakatika set in fifth century B.C. says that the Avagaunthaha wasn't utilized by ladies everyday and at on every occasion. He says that a married girl was expected to place on a vile whereas occupation the general public.[40] this might indicate that it absolutely was not necessary for mateless females to place on a veil. [41] In third century cerium, Mahayana Buddhists conceive to counter this growing netting follow (oguntheti/oguṇthikā) in Lalitavistara Sūtra.[42] this way of netting by married ladies remains current in Hindi-speaking areas, and is thought as Ghoonghat wherever the work of a frock is force over the top to act as a facial veil.[43]

Based on sculptures and paintings, tight bodices or cholis square measure believed have evolved between ordinal century B.C to sixth century A.D in varied regional designs.[44][44] Early cholis were front covering tied at the back; this vogue was a lot of common in components of ancient northern Republic of India. This ancient sort of top or choli square measure still common within the state of Rajasthan these days.[45] Varies sorts of ornamental ancient embroidery like gota patti, mochi, pakko, kharak, suf, kathi, phulkari and gamthi square measure done on cholis.[46] In Southern components of Republic of India, choli is thought as ravikie that is tied at the front rather than back, kasuti is ancient sort of embroidery used for cholis during this region.[47] In Asian nation, choli is thought as cholo or chaubandi cholo and is historically tied at the front.
