Yield Variability and Harvest Failures in Russia, Ukraine and Kazakhstan and Their Possible Impact on Food Security in the Middle East and North Africa

Abstract

Exports from Russia, Ukraine and Kazakhstan (RUK) help to improve global wheat availability and, hence, global food security. During the past 15 years, however, RUK wheat exports have shown high variability, mainly because they have been repeatedly diminished by severe harvest failures. We present an outlook for RUK wheat production and exports up to 2027, taking into account possible yield variability and harvest failures, and focusing on the impact on food security in the Middle East and North Africa (MENA), the world's major wheat importing region. For the analysis we use the stochastic version of the Aglink-Cosimo model. Simulation results show that wheat yields in RUK are a major source of uncertainty for international wheat markets. The projected substantial increases in world market prices due to limited RUK wheat exports threaten food security in MENA and highlight the need for both stabilising RUK yields and novel complementary food security approaches to decrease MENA's vulnerability to disruptions in agricultural world markets.

Price formation within Egypt's wheat tender market: Implications for Black Sea exporters

“…Arnade and Hoffmann (2019) establish that the Black Sea region plays an important role for the international maize markets price discovery, especially in periods of high exports. Araujo‐Enciso and Fellmann (2020) show that the harvest failures in the Black Sea region can have severe effects on food security in the import‐dependent MENA region. Svanidze et al.…”

Changing The Quality Of Life And Its Impact On Food Import Substitution

“…It should be noted that approaches to study the restriction of food import within the framework of their safety and the impact on the quality of life of the population are not correlated with the global goal of achieving the goal of "zero hunger", as well as limiting the growth of national food production relative to the population growth (Porkka et al, 2017). In some countries with a high level of import dependence on the supply of agricultural raw materials, the issues of the quality of imported goods and their impact on the quality of life are sidelined due to the threat of loss of suppliers and market uncertainty (Araujo et al, 2020).…”

Analysis of Food Production and Consumption Based on the Emergy Method in Kazakhstan

“…This shows that rural meat consumption is more vulnerable to social and economic influence than urban meat consumption, to some extent. Moreover, Kazakhstan has a large area of cropland and grassland, but it is easy to understand that its yield does not show a high efficiency for cropland utilization because its famous crop, wheat, has a yield lower than that in Russia [ 65 ]. Compared with the international wheat yield, Kazakhstan’s wheat yield still has much room and potential for improvement.…”
