TLDR
In this paper, the effect of climate change on global potato production was assessed with a simulation model and a grid with monthly climate data for current (1961-1990) and projected (2010-2039 and 2040-2069) conditions.Abstract:
The effect of climate change on global potato production was assessed. Potential yields were calculated with a simulation model and a grid with monthly climate data for current (1961–1990) and projected (2010–2039 and 2040–2069) conditions. The results were mapped and summarized for countries. Between 1961–1990 and 2040–2069 the global (terrestrial excluding Antarctica) average temperature is predicted to increase between 2.1 and 3.2 C, depending on the climate scenario. The temperature increase is smaller when changes are weighted by the potato area and particularly when adaptation of planting time and cultivars is considered (a predicted temperature increase between 1 and 1.4 C). For this period, global potential potato yield decreases by 18% to 32% (without adaptation) and by 9% to 18% (with adaptation). At high latitudes, global warming will likely lead to changes in the time of planting, the use of later-maturing cultivars, and a shift of the location of potato production. In many of these regions, changes in potato yield are likely to be relatively small, and sometimes positive. Shifting planting time or location is less feasible at lower latitudes, and in these regions global warming could have a strong negative effect on potato production. It is shown that heat-tolerant potato cultivars could be used to mitigate effects of global warming in (sub)tropical regions.read more

The ability of climate envelope models to predict the effect of climate change on species distributions
TL;DR: This article evaluated the ability of CEMs to predict species distributions under different climates by comparing their predictions with those obtained with a mechanistic model (MM), in which the distribution of a species is modeled based on knowledge of the species' physiology and the potential distributions of 100 plant species were modeled with an MM for current conditions, a past climate reconstruction (21000 years before present) and a future climate projection (double preindustrial CO2 conditions).

Potatoes and Human Health
TL;DR: The potato is a carbohydrate-rich, energy-providing food with little fat, and many compounds in potatoes contribute to antioxidant activity and interest in cultivars with pigmented flesh is growing.

The effect of climate change on crop wild relatives
TL;DR: There is an urgent need to identify and effectively conserve crop wild relatives that are at risk from climate change and those that are predicted to undergo strong range size reductions should be a priority for collection and inclusion in genebanks.

Is Cassava the Answer to African Climate Change Adaptation
Andy Jarvis,Julian Ramirez-Villegas,Julian Ramirez-Villegas,Beatriz Vanessa Herrera Campo,Carlos E. Navarro-Racines +4 more
TL;DR: It is concluded that cassava is potentially highly resilient to future climatic changes and could provide Africa with options for adaptation whilst other major food staples face challenges.

TL;DR: The genomics era is accelerating the understanding of the key genes and mechanisms underlying potato development, physiology, water and nutrient use efficiency and resistance to biotic and abiotic stresses, and Genomics technologies provide the potential for more rapid, marker-assisted breeding strategies, and afford the opportunity for biotechnological approaches.

TL;DR: In this article, a 0.5° lat × 0. 5° long surface climatology of global land areas, excluding Antarctica, is described, which represents the period 1961-90 and comprises a suite of nine variables: precipitation, wet-day frequency, mean temperature, diurnal temperature range, vapor pressure, sunshine, cloud cover, ground frost frequency, and wind speed.

Potential impact of climate change on world food supply
TL;DR: A global assessment of the potential impact of climate change on world food supply suggests that doubling of the atmospheric carbon dioxide concentration will lead to only a small decrease in global crop production.
