Along with pharmacological applications due to bioactive elements such as flavonoids and glycyrrhizin, licorice has positive influences on the rehabilitation, rejuvenation, and management of salt-affected degraded lands in arid regions. These features made this plant widely appreciated worldwide when climate change is showing detrimental impacts for crop production and food security. However, a growing demand followed by irrational harvesting of wild licorice plants has led to substantial dwindling of its natural habitat. There is an increasing need to protect the plant biodiversity since sustainability can be a problem with wild harvesting. Therefore, it is important to investigate cultivation technologies of licorice under harsh environments, while this plant can adapt to a wide range of climates. Thus, in this review, we studied, analyzed and summarized the literature on licorice cultivation methods counteracting the most common environmental stresses in the Aral Sea region. Particularly, the current knowledge was rationalized regarding on cultivation technologies for alleviating salt stress thereby improving crop production. We also highlighted that future research directions on licorice breeding and genomics that might facilitate to produce more resilient and sustainable licorice genotypes to renovate agricultural productivity under disastrous ecology and climate change of the arid regions. Whereas this area possesses all prerequisite conditions needed for successful cultivation of the alternative cash crop.

Agriculture contributes the most to the economy and provides agro-ecological benefits in the environmentally unsustainable Aral Sea region, but its productivity is steadily dropping. To improve the resilience of farming communities in the region, crop diversification is proposed to enable farmers to grow high-value competitive crops and obtain more stable farm incomes. This study provides long-term, multidisciplinary analyses and strategies for strengthening crop diversification amongst farmers in the Aral Sea region. The study analyzed data provided by the Ministry of Agriculture of the Republic of Uzbekistan and the statistical yearbook of 2000–2020. According to the gross margin study findings, farmers who use diversified cropping systems made considerably higher revenues than farmers relying on mono-cropping practices. This study demonstrates that greater crop diversity contributes to the rational use of natural resources and optimization plans, environmental sustainability, and food security as important natural and socio-economic issues in this region. The study findings suggest that proper crop diversification strategies need to be developed in the Aral Sea region to improve the sustainability of farming systems with enhanced resilience to devastating environmental and climate challenges.

The study examines possible water savings by replacing alfalfa with winter wheat in the Fergana Valley, located upstream of the Syrdarya River in Central Asia. Agricultural reforms since the 1990s have promoted this change in cropping patterns in the Central Asian states to enhance food security and social benefits. The water use of alfalfa, winter wheat/fallow, and winter wheat/green gram (double cropping) systems is compared for high-deficit, low-deficit, and full irrigation scenarios using hydrological modeling with the HYDRUS-1D software package. Modeling results indicate that replacing alfalfa with winter wheat in the Fergana Valley released significant water resources, mainly by reducing productive crop transpiration when abandoning alfalfa in favor of alternative cropping systems. However, the winter wheat/fallow cropping system caused high evaporation losses from fallow land after harvesting of winter wheat. Double cropping (i.e., the cultivation of green gram as a short duration summer crop after winter wheat harvesting) reduced evaporation losses, enhanced crop output and hence food security, while generating water savings that make more water available for other productive uses. Beyond water savings, this paper also discusses the economic and social gains that double cropping produces for the public within a broader developmental context.
