said Hans-Otto Pörtner, Co-Chair of IPCC Working Group II. Landslides and avalanches in high mountains On the other hand, people in mountainous regions are increasingly exposed to hazards and changes in water availability, according to the report. Glaciers, snow, ice, and permafrost are and will continue to decline. This is projected to pose risks to people, for example, through landslides, avalanches, rockslides, and floods. Smaller glaciers in Europe, East Africa, the tropical Andes, and Indonesia are projected to lose more than 80% of their current ice mass by 2100 under high-emission scenarios.

Why Should an Email Marketer Consider the Context
Institute (IFAPA) Alameda del Obispo , in Córdoba, Niue Email List have concluded that the highest yield of rainfed crops is achieved by advancing the sowing date. In a study in which they have combined four agronomic parameters for the first time, they estimate that sowing 45 days before raises the harvest by 30% in sunflower. In wheat, the conclusions are not as emphatic. The work made for the first time combinations in irrigation, fertilization, sowing date and plant density, over six years and focused on sunflower. “By advancing sowing, flowering occurs earlier and, with this, the probability of an extreme temperature event occurring during it is reduced, so the crop avoids the dates with the highest risk of high heat and water stress” , says the IFAPA
researcher Ignacio Lorite to the Discover Foundation, co-author of the study ‘Improving the sustainability of farming systems under semi-arid conditions by enhancing crop management’ , published in the Agricultural Water Management magazine . The Agrifood Engineering and Technology group of IFAPA in Cordoba has been studying sunflower for more than 20 years. Although the acreage has decreased, indicates Lorite, it is still a reference in many rainfed areas in Andalusia and, therefore, suitable for analyzing how to improve yield in drought conditions. As it was impossible to change the meteorological conditions, the starting point of the study was focused on another objective: how to alter the crop cycle through the four parameters mentioned.
