Unsafe air pollution levels affect 9 in10 people globally
Justin Worland, Science Environment, Sept. 27, 2016
More than 90% of the world’s population lives in areas with unsafe pollution levels, the study incorporates data in 3,000 cities and towns across the globe. Unsafe air-pollution levels hit every region tracked, but some areas are worse off than others. Residents of Africa, Asia and the Middle East tend to face the worst pollution, in Europe, more than 60% of high-income cities fall short including Paris and London. Around 15% of cities in high-income in the Americas, including places like Los Angeles and Manhattan, fall short of WHO standards. It is not a problem in the developing world is the all. In developing countries, levels of particulate matter continue to increase in line with economic and industrial growth, and the rise in car ownership.

This research was aimed at defining from the economical point of view, an appropriate surface localized irrigation technology to cultivate coffee trees for the soil climatic conditions of San Andres, from the evaluation of the effect of settled plantations of two moisture areas (52 and 100 % of vital space) and two irrigation intervals (every 3 and 5 days) over agricultural yields and obtain profitability according the technology used. Among the technological variants studied, the best result showed was the one included to wet as minimum 52% of vital area every 5 days, where best yields were obtained (24,46t/ha coffee cherry) and the biggest relations Benefit/Cost (4,19) benefits obtained with relation to capital spent to long term (32,36) to a total cost per irrigation (2,45) as well as the highest net profits (67 377,7 pesos/ha).

Vietnam is feeling strong climate change impacts to production and people’s lives.
Vietnam News, September, 05/2016.
In Vietnam the last few years, drought, unseasonable rain, downpours, long hot spells and extremely cold weather have seriously affected farm production and people’s daily lives. During this year’s dry season the water level of the Mekong River was reported at the lowest level ever in the past 90 years, in some localities, salt water infiltration was reported 120 Km inland, the worst ever in Vietnam’s history. To adapt to climate change, many Vietnamese irrigation experts note the importance of encouraging the participation of all social sectors in adopting the idea that water is a kind of commodity that everyone needs to preserve.

Water and Irrigation Vol .: 7, No. 1: 21-22, September, 2016, Spain.
During 2016 as a result of global warming and the impact of human activity there have been fires of great economic importance affecting different states of the United States and countries of the European Union and burned a large area more than of 250 thousand ha and more than 210 thousand ha respectively. Deforestation, forest fires and the impact of human activity contribute to increased levels of C02 and thus help to increase the temperature. Prospects fire also considered high for other countries such as Brazil and Australia where temperatures are rising.More heat on the planet indicates more activity natural forces of the Earth which gain energy to the extent that this is heated and endangers the balance of the planet and the sustainability of humanity.

Claim that climate change destroys 20% of potatoes a year.
August 26, 2016. Panama.
High temperatures and erratic rainfall have made that potato production in Latin America is decreasing each year between 10 and 20%, since the crop is harvested until it reaches the consumer’s plate can lose up to 40 % of it by poor organization in the supply chain. By 2050, many glaciers in the Andes will disappear which will generate a big water problem and an increase in insects, that previously don’t climbed the height and the cold weather, all these factors together can contribute to affect food security in Latin America.

Water and Irrigation Vol .: 7, No. 1: 19-20, August, 2016, Spain.
In 2016 torrential rains have caused flooding in the states of Louisiana, Texas, Oklahoma, Arkansas, Mississippi, Tennessee, Missouri and Illinois. Being the most damaged Louisiana and Texas to the southern United States, where there have been annual rainfall accumulated until August in Baton Rouge in Louisiana 2510mm and 1724 mm at the airport Bergstrom in Texas, it has seen a great climatic instability in the region. Flooding in Louisiana as a result of storms have killed 13 people, economic losses are valued at over one billion dollars. It has declared a state of natural disaster for the State of Louisiana.

Desertification: threat to agricultural land.
Mayors of Mexico magazine. Posted By Editorial. August 12, 2016 Mexico.
Degradation and desertification of Mexican agricultural land is a problem that threatens about 80 percent of the field. At the government level it seek to identify policies at local and regional levels that reduce erosion involving all levels of society, through alternative sustainability and reduced excessive water use techniques. areas vulnerable to human activity land and excessive use of agricultural pesticides and heavy machinery being degraded areas that are not necessarily in desert conditions are identified. Institutions attack areas that still have weak deforestation and desertification and sustainable management can stand there to promote the use of special machinery and technology, with the implementation of rescue strategies.
