One good example is the production of cereals. Cereals have been characterized by far one of the most important sources of food consumption globally. Since the diet has been diversified, the consumption of cereals has changed. More specifically, in developing countries, 30 years ago cereals were represented 61% of total calories. Nowadays, this amount decreased to 56%.
India has one of the largest concentrations of tribal population in the world. The forest plays a vital role in the economy as well as daily needs of the tribals. In times of scarcity when the staple food is in short of supply, tribal’s collect many types of wild roots and tubers to supplement their meager food available at home (Vidyarthi, 1987). Tuber crops are the third important food crops after cereals and legumes. World production of the crop is estimated to be 5.5 million tons annually and provides about one third of food intake of more than 400 million people in the tropics.
Despite being one of the top 10 most water-scarce countries in the world, it is astonishing how this country has efficiently managed to be sustainable. The secret lies also in the type of irrigation the country has adopted. Agricultural sector consumes two-thirds of all water available in the Emirates. If a dry country like UAE adopts sprinkler irrigation like the countries with abundant water resource, 60% of the water would evaporate before it is absorbed by the plants. As a result, only 40% of the water intended for irrigation would be used, which is not evenly distributed as well.
The attainment of agriculture sustainability and self-sufficiency in food production are the predominant concern for every developing country in the world, especially to India. India is the seventh largest country in terms of geographical area, second most populated and twelfth largest economy in the world. The decadal growth rate is 17.6 percent and average literacy is 74.04 percent as per 2011 census (P Maneesh, 2015). Food security could be achieved only through the devices of agricultural development, apart from attainment of self-sufficiency in food production; agriculture is the key sector of the country and country can progress only through agriculture development. India has chiefly been an agrarian based economy, with agriculture sector contributing the largest share to gross domestic product (GDP) and employment.
To be able to produce rice, water is considered to be the most critical resource due to its significant use in irrigation. Worldwide, 70% of water is used especially in rice cultivation (Van der Hoek et al., 2001 as cited in Rejesus et al., 2010). About 17 percent of the cropland in the world is irrigated wherein, 60 percent of it is located in
Economic Role Milk Plays an important role in economy of Pakistan. Dairy sector plays major role in GDP contribution of Pakistan. In livestock sector , milk accounts for 72% value of output . The importance of milk only beats the collective value of • wheat, • rice, • maize and • sugarcane in the country. Livestock produces 42.119 million tons of milk, Making the Pakistan 4th largest manufacturer of milk in the world (GOP, 2008).
Water Resources of Pakistan Water is the basic human need and as we know a human can live up to 80 days without food, but only a few days without water. Water is the basic need of every living thing on earth as we know no living thing can live without water. However, its use in unbalanced and unmanaged way has made it reduced its quantity to a great extent. Pakistan is now facing a big challenge to meet the requirements for its population and water is becoming scarce in Pakistan. In Pakistan, about 96% of its available water is being utilized for agriculture and the remaining 4% for domestic, industrial and other purposes.
Alternative sources, such as bagasse from sugar cane and rice husk are being utilized and further developed as fuel for power projects. The Philippines has large agriculture, forestry and livestock industries, which results in the consumption of biomass energy widely throughout the country. 6.7 Korea: Hydropower In 2011, 7.8TWh of hydropower was produced, making hydropower the country’s top renewables source. It has been estimated that Korea has small-scale hydropower potential of 1.5GW. Installed capacity represents less than 5% of domestic potential, indicating significant untapped resources.
The irrigation process, used in agriculture, occupies the third largest usage of water in the United States and the largest use of fresh water. Fresh water is any water that its origins differ from the oceans. Irrigation, in agriculture, is used to grow and maintain crops. Research states that between 15% to 35% of water used in agriculture is unsustainable and that agriculture wastes 60% of the water it uses each year because of leaky irrigation systems, wasteful field application methods, cultivation of thirsty crops not suited to the environment, limited awareness of water scarcity and weak environmental
It is used directly for drinking, sanitation, and food production, and only slightly less directly for economic output across a very broad range of sectors. There is only 2.5 percent of fresh water share in total global water availability, and it is only 1.2 percent of all fresh water. It is thus a primary basis for sustaining human well-being for generations to come. Dr. Bhumbla, a former Commissioner of Agriculture of India, states, “There is absolutely no doubt that if stress laid on
