Juan G. R. The world population sustainability demands more water available and agricultural production.
Water and Irrigation Vol. 4, No. 1: 13-14, July, 2013, Spain.
The future growth of the world population by about 18% for the year 2030, will enable it exceeded 8.2 billion people and will involve a greater intake of: food, raw materials, materials, energy, water, supplies of all kinds, signaling that corresponds to the UN and all the countries concerned and involved, take the necessary measures to ensure social welfare and sustainability of humanity. . Increasing world population demand: higher water consumption, an increase of water stored, greater management of water sources, strategic handling of irrigation water, a larger sewage treatment, an increase in water infrastructure, an increase of irrigated areas, major scientific and technical activity. To ensure an increase in global agricultural yields, also the irrigation and drainage is essential through genetics obtaining more productive varieties under irrigation and dry conditions, and apply new agricultural strategies.
The steady increase in the global population, low birth control by no developed countries, excessive pollution of the environment, inadequate protection of the marine environment, the systematic neglect of agriculture in many countries, the high demand for food, inadequate water management, accelerated loss of different species of plants, animals and fish, the effects of climate change, the loss of millions of hectares of deforestation, erosion and desertification threaten the sustainability of humanity and said that requires greater control of international institutions to ensure a more efficient management of the problem. The future growth of the world population by about 18% for the year 2030, will enable it exceeded 8.2 billion people and will involve a greater intake of: food, raw materials, materials, energy, water, supplies of all kinds etc. signaling that corresponds to the UN and all the countries concerned and involved, take the necessary measures to ensure social welfare and sustainability of humanity.
At present the world’s food production is enough to feed the current population, despite the unequal distribution of food, high prices for the sale of food and inadequate infrastructure in the primary sector of many underdeveloped countries of planet cause that the number of hungry people exceeds one billion inhabitants. It is the agricultural sector and the food industry in cooperation with the UN to ensure the production of food needed to cope with future growth in humanity, but today the agricultural sector in many countries suffer a systematic deterioration as a consequence of the low profitability of many farms, the labor shortage, as well as by the low standard of living of the sector, which has largely driven the migration of people from rural to urban.
According to the UN one in three people living in a water scarce country moderate to high, it is possible that by 2030 water shortages affect nearly half of the world population, as demand may exceed by 40% supply. There is increasing competition for available water between farmers, between industry and agriculture, between town and country, between watersheds ups and downs, it means it must work together to protect and manage this limited and fragile resource. Cooperation in the area of water is crucial for the security, the fight against poverty, the social justice and gender equality. Good management and cooperation between different user groups promote access to water, fighting against it scarcity and contribute to poverty reduction. The cooperation enables more efficient and sustainable use of water resources and result in mutual benefits and better living conditions. It is also essential for the preservation of water resources, protection of the environment.
. The global population growth demand: increased consumption of water quantity and quality, an increase of water stored, further exploitation of sources of surface and groundwater supply, strategic management of irrigation water, more treatment wastewater, increased water infrastructure, an increase of irrigated areas, increased scientific and technical activity since water is a strategic element that stabilizes and increases agricultural production growth, currently irrigated areas is less than the growth of world population and demand more investment. To ensure an increase in global agricultural yields, also the irrigation and drainage is essential through genetics obtaining more productive varieties under irrigated and rainfed conditions of elevated temperature, consistent with climate change, also need to implement new strategies: mechanization, fertilization, pest and disease control, crop rotation, food preservation, in order to obtain high yields, good product quality and adequate economic efficiency.
