Empirical modeling of the impact of climate change on altitudinal shift of major cereal crops in South Tigray, Northern Ethiopia

Ethiopia’s wheat production pathways to self-sufficiency through land area expansion, irrigation advance, and yield gap closure

“…Thus, expansion of wheat into virgin or under-utilized land presents risks, and wheat area expansion needs to carefully consider the role of these lands in biodiversity conservation, carbon sequestration and other ecosystem services, and crop and nutritional diversification [ 1 , 19 ]. Moreover, the future suitable land area for wheat production is likely to decrease with changing climate, and altitudinal shift of the crop to higher elevations is expected [ 49 ].…”

Overcoming barriers to climate change adaptation policy implementation: insights from Ethiopia

“…The change in climate is shifting ago-ecological zones towards desert and semi-arid classifications, thereby affecting crop production across some parts of Africa (Kala et al, 2012). In the Tigray region of Ethiopia, evidence shows that wheat and barley will migrate upward along the altitudinal gradients in the next eighty years, and suitable areas for these crops are expected to decline significantly with future changes in climate conditions (up to 16-100 per cent) (Gebresamuel et al, 2022). However, the yield of maize and sorghum may increase in some parts of Tigray due to projected increase in the long season rainfall totals (2030-2050) (Hadgu et al, 2015).…”
