“…Fourthly, by further analyzing the results for countries grouped with similar characteristics, for the four major cereals, the presence of club convergence is identified at geographic location and income level, simultaneously. Faced with worse food insecurity status in recent years, continued elimination of barriers to agricultural technology diffusion, by further strengthening cross-border cooperation within and outside the region to improve cereal yield and construction of resilient agri-food systems in the ECA are highly recommended, especially in Central Asia, where the water-energy-food-ecology (WEFE) system is particularly vulnerable [53,54], and financial and technical support from the international community is urgently needed.…”

The state of food security in the world, including that of Europe and Central Asia (ECA), was highlighted in 2020 by the outbreak of the COVID-19 pandemic, when the fact that the food security status of millions of people in ECA, particularly the most vulnerable and those living in fragile contexts, would deteriorate if swift action was not taken as soon as possible became apparent. Improving cereal yield is the key for the ECA to achieve the Sustainable Development Goal (SDG) Target 2.1 to end hunger by 2030. Impressive cereal yield growth has been witnessed within the ECA from 1991 to 2020, but there is still significant variation across the five sub-regions. This paper aimed to analyze the evolutionary trends and convergence of cereal yield in countries of the ECA from 1991 to 2020 for four major cereals: wheat, maize, barley and oats. The findings show that there is strong evidence of σ-convergence and absolute and conditional β-convergence for cereal yield in the ECA, which indicates that countries with low yield in the initial stages have totally experienced higher growth rate, and yield in countries farther away from the steady-state have to have faster growth rate to converge to the steady-state. The presence of club convergence is also identified in terms of geographic location and income level, simultaneously. Therefore, cereal yield in the ECA has converged to the whole and to different groups at the same time, which provides some evidence of agricultural technology spillover effect in the region.

“…Implementers from four different categories are represented, including UN Officials; National Ministry Officials; University/Academic Researchers; and representatives of advocacy groups and Non-Governmental Organizations (NGOs). Focusing on these SDGs related to food production, water use, and food security were particularly important in Central Asia where post-soviet transition and a lack of water-energy-food nexus integration and crosscountry coordination have created development challenges (Rakhmatullaev et al, 2018;Qin et al 2022).…”

As the world passes the midpoint of the 2030 United Nations Sustainable Development Goals (SDGs), clarity about the implementation of this agenda becomes increasingly critical. Equally important is the extent to which the SDG framework is succeeding or failing in different contexts. This study explores the role and importance of the “implementers”, mid-level actors that bridge policymaking between national leaderships who set policy and grassroots efforts. Focusing on three SDGs (#2, 6 and 15), thirty (30) such implementers were selected through purposive sampling combined with subsequent reputational strategies. The knowledge and attitudes of these actors toward the goals and progress of their respective nations were evaluated through structured interviews. While the general outlook on their countries’ capacity to reach the proposed goals was positive, the detailed review of SDG targets showed signs that those in “the middle” were highly uncertain as to whether these goals could be reached. Considering the critical role of these implementers in translating policy to action, this creates serious concern about the path forward in sustainable development moving toward 2030 and beyond. Moreover, critical reconsideration of the process of implementing the SDGs needs to be undertaken to capitalize on the expertise and strategic capacity of “the middle” of sustainable development.

“…Because each of the systems, including vegetation, water, soil and atmosphere, will be affected in a variety of ways by reduced streamflow, if too much water is used for irrigation and streamflow continues to decrease, irreversible ecological disasters are probable, although rarely does one know just when such an event will happen (Palmer and Ruhi, 2019;Morganstein and Ursano, 2020). Balancing water use between human food production and the needs of the environment is extremely important for local communities and governments, but also complex and difficult to achieve in practice (Qin et al, 2022). Thus, an explicitly formulated strategy for streamflow forecasting and management is needed, especially in the climate change context.…”

Comparative analysis of the impacts of precipitation and land use on streamflow from adjacent catchments is critical to exploring pathways toward water security and sustainable development. In this work, two adjacent catchments (the Mayinghe and Xidahe, abbreviated as MYC and XDC, respectively) in northwestern China were selected to compare the impacts of precipitation change and land use alteration on streamflow change during 1956–2019 using field observation streamflow data and satellite data. An opposite trend of streamflow was found for the two catchments from 1956 to 2019: the streamflow decreased significantly in the MYC (-0.63 × 107m3/10a, p < 0.05), while it increased in the XDC (0.71 × 107m3/10a, p < 0.05). Land conversion dominated the streamflow reduction in the MYC, with a contribution of about 68.3%. In the XDC, precipitation was confirmed to be the major factor driving the increase in streamflow. The streamflow for farmland irrigation reached 27.97 × 104 m3/km2 in the MYC, which was the leading factor of streamflow reduction in the basin. The findings obtained from this work can shed light on the quantitative understanding of streamflow changes in small catchments and offer a scientific basis for sustainable water management in other inland river basins.
