The Highland Potato Famine (Scottish Gaelic: Gaiseadh a' bhuntàta) was a period of 19th-century Highland and Scottish history (1846 to roughly 1856) over which the agricultural communities of the Hebrides and the western Scottish Highlands (Gàidhealtachd) saw their potato crop (upon which they had become over-reliant) repeatedly devastated by potato blight.
The flora of Scotland is an assemblage of native plant species including over 1,600 vascular plants, more than 1,500 lichens and nearly 1,000 bryophytes.The total number of vascular species is low by world standards but lichens and bryophytes are abundant and the latter form a population of global importance.
Until 1750, potatoes had been relatively uncommon in the Highlands. With a crop yield four times higher than oats, they became an integral part of crofting. [5]: 49 After partial crop failures in 1836 and 1837, a severe outbreak of potato blight arrived in Scotland in 1846. Blight continued to seriously affect the Highland potato crop until ...
The European potato failure was a food crisis caused by potato blight that struck Northern and Western Europe in the mid-1840s. The time is also known as the Hungry Forties . While the crisis produced excess mortality and suffering across the affected areas, particularly affected were the Scottish Highlands , with the Highland Potato Famine and ...
Phytophthora infestans is an oomycete or water mold, a fungus-like microorganism that causes the serious potato and tomato disease known as late blight or potato blight. Early blight , caused by Alternaria solani , is also often called "potato blight".
These potatoes also have coloured skin, but many varieties with pink or red skin have white or yellow flesh, as do the vast majority of cultivated potatoes. The yellow colour, more or less marked, is due to the presence of carotenoids. Varieties with coloured flesh are common among native Andean potatoes, but relatively rare among modern varieties.
Scotland suffered its last major subsistence crisis when the potato blight reached the Highlands in 1846. In the twentieth century Scottish agriculture became susceptible to world markets. There were dramatic price rises in the First World War , but a slump in the 1920s and 1930s, followed by more rises in the Second World War .
