Late blight was responsible, in large part, for the Irish Potato Famine in the 1840âs, which resulted in the death and mass emigration of millions of people. Each year, Late blight reduces the yields of potatoes and tomatoes in the field and can cause major losses in potato tubers in storage. Late blight is found in most potato and vegetable growing regions of Canada and North America. Major outbreaks occur occasionally in Alberta (the last one was in 1993).
Disarmament is the act of reducing, limiting, or abolishing weapons. Disarmament generally refers to a country's military or specific type of weaponry. Disarmament is often taken to mean total elimination of weapons of mass destruction, such as nuclear arms.
UN treaties are the legal backbone of disarmament efforts: the Chemical Weapons Convention has been ratified by 190 States, the Mine-Ban Convention by 162 and the Arms Trade Treaty by 69. At the local level, UN peacekeepers often work to implement disarmament agreements between warring parties.
