The first-ever study synthesizing risks posed by climate and environmental changes in the Mediterranean zone. As the Mediterranean Basin is experiencing the impact of climate change more than ever, an international network of scientists has worked together to synthesize the effects of climate change and environmental problems, as well as the incurred risks, in the region, to facilitate decision-making in addressing the issues. In politically unstable countries, environmental change is an increasingly relevant factor for socio-economic risks, due to famines, migration and conflict. Human security will also be threatened due to extreme weather, such as a rise in sea level posing a higher risk of storm surges for people living in coastal areas in the region.

5 Mayor Crops in the crosshairs of Climate Change

5 Mayor Crops in the crosshairs of Climate Change

Dan Charles, October 25, 2018

 Climate change is coming like a freight train and our food, so dependent on rain and suitable temperatures, sits right in its path. The plants that nourish us won’t disappear entirely. But they may have to move to higher and cooler latitudes, or farther up a mountainside. Some places may find it harder to grow anything at all, because there’s not enough water. There are 5 mayor crops and food-growing places in the crosshairs of climate change that will see the impact as: wheat, peaches, coffee, corn and almonds. The global warming continue manifesting with great intensity in different countries and crops, put the food production in serious difficult.

Floods fight in Mallorca demand more protection works.

Juan G. R., Juan G. M. and Juan G. R.  Floods fight in Mallorca demand more protection works. 

 Water and Irrigation Vol.: 9, No. 1: 16-17, October 2018, Spain.

 In the fight against flooding in Sant Lorenç Mallorca, which is so prone to this type of event, it must protect the area with contour channels that dampen the entrance of external waters to the area and improve the urban surface drainage and drainage of the internal waters within the town, in order to evacuate the runoff of the waters in the affected area in the shortest possible time and ensure that human and economic losses are minimized. Accumulated rainfall of 220 mm was registered in 4 hours due to the effect of the cold drop. As the water did not have a channel to move, it did it through the narrow streets of the town, which caused great mud drags and floods, which provoked the human losses of 13 people, the drag of cars, damage to infrastructures and large losses in material goods valued in millions of euros.

Heatwaves its effect and drought in 2018

Juan G. R., Juan G. R. and Juan P. J. Heatwaves its effect and drought in 2018. 

Water and Irrigation Vol: 9, No. 1: 13-15, October 2018, Spain.

Heat waves and drought have manifested with great intensity in 2018, in different countries of Asia, Africa, Europe, America and Oceania as a result of greater global warming, causing hundreds of human losses and billions of dollars in losses of harvests in different crops, registering the highest temperature of 51.3 ° C, in the Sahara desert, Algeria. Prolonged heat waves, accompanied by low rainfall intensify the drought. Greater control of greenhouse gas emissions in different countries is necessary to enable a better future for generations to come and a more sustainable planet.

Prevent deadly heat waves in China due to climate change

Prevent deadly heat waves in China due to climate change

By The nuevodia.com  Science, August 1, 2018.

The new findings show that the plain of northern China faces the greatest risks to human life, this area will be the warmest place for deadly heat waves in the future, especially under climate change. The three regions studied by the researchers were chosen because past records indicate that the combined levels of temperature and humidity reached higher extremes there than in any other landmass. The new study indicates that under normal scenarios of greenhouse gas emissions, that threshold will be reached several times in the region of the North China Plain between 2070 and 2100.

Floods in Japan require improving the efficiency of surface and internal drainages.

Juan G. R. Floods in Japan require improving the efficiency of surface and internal drainages.

 Water and Irrigation Vol .: 9, No. 1: 11-12, July 2018, Spain.

In the fight against floods and the effects of climate change in Japan, it is necessary to increase the efficiency of surface and internal drainages in urban and rural areas, in line with the current climate situation in the country, which will continue to be more disastrous in the future years, in order to achieve a more effective protection of human lives and of material and economic goods. Floods as a result of torrential rains in Japan have caused some 209 deaths as well as damage to roads and bridges infrastructure, landslides, constant water and electricity cuts and transport disruptions, have been evacuated around 5 million people, The meteorological phenomenon has also damaged agriculture and livestock and has hurt Japanese industrial companies.

Emissions of C02 in the main polluting countries.

Juan G. R. Emissions of C02 in the main polluting countries.

Water and Irrigation Vol .: 9, No. 1: 9-10, June 2018, Spain.

Global emissions of carbon dioxide have mainly increased due to the great impact of human activity and the increase in around 80 million / year of the world population. The CO2 emissions of the six most polluting countries are made up of China, the United States, India, the Russian Federation, Japan and Germany, all located in the northern hemisphere and together represent 61% of the world total. China and the USA, with a cumulative of 44%. The cumulative emissions of C02 from the countries located in the northern hemisphere are greater than 70% of the total. The emissions of greenhouse gases in cities represent a large percentage of the total in these countries, as indicated by different studies. It is considered that currently the total emissions of C02 are above the levels of 36,000,000 Kilotons.
