Green Revolution in the context of "Punjab region"

A cereal is a grass cultivated for its edible grain. Cereals are the world's largest crops, and are therefore staple foods. They include rice, wheat, rye, oats, barley, millet, and maize (corn). Edible grains from other plant families, such as amaranth, buckwheat and quinoa, are pseudocereals. Most cereals are annuals, producing one crop from each planting, though rice is sometimes grown as a perennial. Winter varieties are hardy enough to be planted in the autumn, becoming dormant in the winter, and harvested in spring or early summer; spring varieties are planted in spring and harvested in late summer. The term cereal is derived from the name of the Roman goddess of grain crops and fertility, Ceres.

Cereals were domesticated in the Neolithic around 8,000 years ago. Wheat and barley were domesticated in the Fertile Crescent. Rice and some millets were domesticated in East Asia, while sorghum and other millets were domesticated in West Africa. Maize was domesticated by Indigenous peoples of the Americas in southern Mexico about 9,000 years ago. In the 20th century, cereal productivity was greatly increased by the Green Revolution. This increase in production has accompanied a growing international trade, with some countries producing large portions of the cereal supply for other countries.

Punjab (/pʌnˈdʒɑːb/ pun-JAHB; Punjabi: Panjāb, pronounced [pəɲˈd͡ʒaːb] ) is a geographical, ethnolinguistic, and historical region in South Asia, located in its northwestern part, comprising areas of modern-day Pakistan and northwestern India. It is primarily inhabited by the Punjabi people. Lahore is its largest city and historic capital, with other major cities including Faisalabad, Rawalpindi, Gujranwala, Multan, Sialkot, Sargodha, and Bahawalpur in Pakistan; alongside Ludhiana, Amritsar, Chandigarh, Jalandhar, Patiala, Mohali, Bathinda, Firozpur, and Fazilka in India.

Punjab grew out of the settlements along the five rivers, which served as an important route to the Near East as early as the ancient Indus Valley civilization, dating back to 3000 BCE, followed by migrations of the Indo-Aryan peoples. Agriculture has been the chief economic feature of the Punjab and formed the foundation of Punjabi culture. The Punjab emerged as an important agricultural region, especially following the Green Revolution during the mid-1960s to the mid-1970s, and has been described as the "breadbasket of both India and Pakistan."

Agricultural productivity is measured as the ratio of agricultural outputs to inputs. While individual products are usually measured by weight, which is known as crop yield, varying products make measuring overall agricultural output difficult. Therefore, agricultural productivity is usually measured as the market value of the final output. This productivity can be compared to many different types of inputs such as labour or land. Such comparisons are called partial measures of productivity.

Agricultural productivity may also be measured by what is termed total factor productivity (TFP). This method of calculating agricultural productivity compares an index of agricultural inputs to an index of outputs. This measure of agricultural productivity was established to remedy the shortcomings of the partial measures of productivity; notably that it is often hard to identify the factors cause them to change. Changes in TFP are usually attributed to technological improvements.

Punjabi culture grew out of the settlements along the five rivers (the name Punjab, is derived from two Persian words, Panj meaning "Five" and Âb meaning "Water") which served as an important route to the Near East as early as the ancient Indus Valley civilization, dating back to 3000 BCE. Agriculture has been the major economic feature of the Punjab and has therefore formed the foundation of Punjabi culture, with one's social status being determined by landownership. The Punjab emerged as an important agricultural region, especially following the Green Revolution during the mid-1960s to the mid-1970s, has been described as the "breadbasket of both India and Pakistan". Besides being known for agriculture and trade, the Punjab is also a region that over the centuries has experienced many foreign invasions and consequently has a long-standing history of warfare, as the Punjab is situated on the principal route of invasions through the northwestern frontier of the Indian subcontinent, which promoted to adopt a lifestyle that entailed engaging in warfare to protect the land. Warrior culture typically elevates the value of the community's honour (izzat), which is highly esteemed by Punjabis.

The International Rice Research Institute (IRRI) is an international agricultural research and training organization with its headquarters in Los Baños, Philippines, and offices in seventeen countries. IRRI is known for its work in developing rice varieties that contributed to the Green Revolution in the 1960s which preempted the famine in Asia.

The institute, established in 1960 aims to reduce poverty and hunger, improve the health of rice farmers and consumers, and ensure environmental sustainability of rice farming. It advances its mission through collaborative research, partnerships, and the strengthening of the national agricultural research and extension systems of the countries IRRI works in.
