Stevia as a Partial Alternative to Sugar: Enhancing Food Security in Central Asia

nCa Report

Introduction

Central Asia faces significant food security challenges, particularly with vulnerabilities in key commodities like sugar, cooking oil, and tea. Sugar, in particular, relies heavily on imports due to limited domestic production in countries such as Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, and Turkmenistan.

While stevia (Stevia rebaudiana) cannot fully replace traditional sugar from beetroot or sugarcane—due to differences in bulk, texture, and functionality in applications like baking—it offers a viable partial substitute in beverages, tabletop sweeteners, and certain processed foods.

This report argues that local cultivation and adoption of stevia can reduce sugar imports by a significant extent, estimated at 10-30% of current consumption, while providing substantial health benefits. Drawing on condensed data from reliable sources like the FAO, scientific studies, and market analyses, the analysis focuses on consumption patterns, replacement potential, and stevia’s role as a “health protection miracle.”

Sugar Vulnerability in Central Asia

The region imports most of its sugar, exacerbating food security risks from global price fluctuations, supply chain disruptions, and climate impacts on major exporters like Brazil.

In 2022, total sugar consumption across Central Asia was approximately 2.18 million tons, with limited local production (e.g., Kazakhstan produced only 164,400 tons in 2024, down 25% from the prior year). Uzbekistan and Kazakhstan are the largest importers, with Uzbekistan accounting for a dominant share of regional imports.

High per capita consumption in some countries, like Kyrgyzstan at 52.3 kg/year, underscores dependency.

Stevia as a Partial Alternative: Consumption Data and Replacement Potential

Stevia’s intense sweetness (200-450 times that of sucrose) allows minimal quantities to provide equivalent sweetness, making it cost-effective and land-efficient. It requires 87-89% less land and 92-95% less water than sugar per unit of sweetness, with greenhouse gas emissions at just 5.7-10.2% of sugar’s.

Central Asia’s semi-arid climate and soils (e.g., loamy in river valleys) are conditionally suitable for stevia, especially in irrigated southern areas like Uzbekistan’s Fergana Valley, where it can be grown as an annual crop with drip irrigation yielding 3-4 tons of dry biomass per hectare. Steviol glycosides (8-12% of dry leaves) from 1 hectare can equate to 30-50 tons of sugar sweetness, far surpassing sugar beet yields of 5-7 tons per hectare.

Country-specific consumption and potential stevia coverage (based on 20-30% replacement in suitable categories like beverages, which account for ~25-30% of global sugar use, and partial in dairy/bakery) are as follows:

Country	Annual Consumption (2022, tons)	Per Capita (kg/year)	Estimated Stevia Replacement %	Potential Import Reduction (tons)
Kazakhstan	631,000	32.5	20-30%	126,200-189,300
Uzbekistan	891,000	25.7	20-30%	178,200-267,300
Kyrgyzstan	346,000	52.3	20-30%	69,200-103,800
Tajikistan	191,000	19.2	20-30%	38,200-57,300
Turkmenistan	123,000	19.2	20-30%	24,600-36,900

This 20-30% estimate reflects stevia’s full replacement in beverages and juices, up to 50% in bakery/dairy, but none in bulk-requiring uses.

Region-wide, this could displace 436,400-654,600 tons annually, or 20-30% of 2.18 million tons, with minimal land (e.g., 2,000-3,000 hectares at 200 kg glycosides/ha yielding 30 tons sugar equivalent each). Profitability is high, with stevia costing 36% less per sweetness unit than sugar.

Stevia as a Health Protection Miracle

Beyond sweetness, stevia is a natural, zero-calorie powerhouse with proven health benefits from scientific studies. It aids diabetes management by lowering blood glucose and glycemic index in products like juices and jellies.

Antioxidant and anti-inflammatory properties combat obesity, hypertension, and cancer, while antimicrobial effects reduce dental caries. Studies show no toxicity, with benefits for kidney function and gut health. In Central Asia, where diabetes and obesity rates are rising, stevia supports public health by enabling low-calorie foods without compromising taste.

Conclusion

Stevia offers a cautiously encouraging path to bolster Central Asia’s food security by reducing sugar imports by 20-30%, leveraging local cultivation in suitable climates. Its health benefits amplify this impact, positioning it as more than a sweetener—a tool for healthier populations amid growing chronic disease burdens. /// nCa, 13 January 2026
