Total eight Vavilovian centers of origin for crop plants. This regions includes all cultivated vegetables crops. Domesticated plants differ from their wild progenitors in several morphophysiological traits, most of which are
associated with seed retention, dormancy and germination, growth habit, size, colour, and/or edibility of economically
important organs. Crop wild relatives includes crop ancestors as well as other species more or less closely related to crops. they may be from different gene pools.They are a critical source of genes for resistance to diseases, pests and stresses such as drought and extreme temperatures
The history of agriculture is the story of how humans transformed wild plants and animals into domesticated ones for their benefit. Agriculture began independently in different parts of the world, and involved a diverse range of species. The development of agriculture about 12,000 years ago changed the way humans lived, as they switched from nomadic hunter-gatherer lifestyles to permanent settlements and farming
Some of the earliest crops that were domesticated include wheat, barley, peas, lentils, chickpeas, and flax in the Levant; rice, soybeans, and azuki beans in China; potatoes, tomatoes, peanuts, and coca in South America; sorghum, millet, yams, and cowpeas in Africa; and teff and coffee in Ethiopia1. Some of the earliest animals that were domesticated include pigs, sheep, cattle, and camels in Mesopotamia and Turkey; llamas, alpacas, and guinea pigs in South America; and sanga cattle in North-East Africa
Agriculture has evolved over time with the development of new technologies, techniques, and practices. Some of the major milestones in agricultural history include the British agricultural revolution in the 18th century, which introduced crop rotation, selective breeding, and mechanization; the Green Revolution in the 20th century, which increased crop yields through the use of synthetic fertilizers, pesticides, irrigation, and high-yielding varieties; and the biotechnology revolution in the 21st century, which introduced genetically modified crops, precision agriculture, and vertical farming
The history of agriculture in India dates back to the Neolithic age, some 9000 years ago, when early cultivation of plants and domestication of crops and animals began in the north-western part of the subcontinent. Wheat, barley, and jujube were some of the first crops that were grown by the ancient farmers
Over time, Indian agriculture diversified and expanded to include rice, millets, pulses, cotton, sugarcane, spices, fruits, vegetables, and livestock. Indian agriculture also developed various techniques and practices such as irrigation, crop rotation, fertilization, pest control, seed selection, and storage. Indian agriculture was influenced by various factors such as geography, climate, culture, religion, trade, and politics13.
Indian agriculture underwent significant changes after independence in 1947. The government introduced various reforms and policies to improve agricultural productivity, such as land reforms, cooperative movements, agricultural research and extension, subsidies, credit facilities, minimum support prices, public distribution system, green revolution, white revolution, blue revolution, and biotechnology revolution. These initiatives helped India achieve food security, self-sufficiency, and export surplus in many agricultural commoditie
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
