Alternative Crops for Sustainable Sugar Self-Sufficiency in Central Asia

nCa Report

Introduction

In the previous report, we looked at the potential Stevia-based sweeteners to help replace about 30% of the total sugar imports of Central Asia. This report is continuation of the search for alternatives to enable Central Asia to reduce its dependence on the imported sugar.

Both of these are accompanying extensions to the main report – Vulnerabilities in the Food Security Mix of Central Asia – which is available in the series of our nCa Special Reports.

Central Asia’s food security is increasingly threatened by global disruptions, climate change, and dependency on imports for essential commodities. Among the most critical vulnerabilities are sugar, cooking oil, and tea, which expose the region to price volatility, supply chain risks, and environmental pressures.Food Security in Central Asia: Countries Have to Strengthen Cooperation

Sugar imports dominate due to limited domestic production, while cooking oil relies heavily on sunflower and cottonseed, often insufficient amid arid conditions. Agrifood Trade and Food Security in Central Asia – World Bank

Tea, a staple in regional diets, faces similar import reliance from China and South Asia. Food Security and the Agricultural Cooperation Agenda in Central Asia – University of Central Asia

To address these, targeted strategies are essential. For sugar, alternative crops can enhance local production, as explored below. nCa will issue a separate report on cooking oil in its nCa Special Reports series, focusing on sustainable oilseed expansion.

For tea, however, the soil and climatic conditions of Central Asia—marked by continental extremes, low precipitation, and alkaline soils—are largely unsuitable for commercial cultivation, which thrives in humid, subtropical environments.Regional Overview of Food Security and Nutrition in Europe and Central Asia – FAO

Instead, emphasis should be on maintaining open supply chains with China, the primary supplier, through trade agreements and infrastructure investments to ensure adequate and affordable tea supplies amid potential geopolitical tensions.

Crop Alternatives for Sugar Production

Central Asia’s continental climate, with hot summers, cold winters, and low rainfall (100-400 mm annually), combined with varied soils from fertile chernozems to saline sierozems, supports several crops for sucrose, syrups, or natural sweeteners like inulin. These can reduce sugar imports by enhancing local sweetener production, leveraging existing irrigation from rivers like the Amu Darya.Food security amid the COVID-19 pandemic in Central Asia – ScienceDirect

Our previous report looked at the potential of Stevia and this report explores some other possibilities. While none fully replace imported sugar, they offer sustainable options.

1. Sugar Beet (Beta vulgaris)

Sugar beet is highly suitable for Central Asia’s temperate zones, thriving in loamy soils (pH 6.0-7.5) and requiring 500-700 mm of irrigation.Ecological and Agronomic Evaluation of Sugar Beet Hybrids – IJAGBIO

It fits the 120-180 frost-free days in Kazakhstan and Uzbekistan, with yields of 50-70 tons/ha of roots, producing 5-10 tons/ha of sugar.Sugar beet production in the Republic of Kazakhstan – Revista Espacios

Expansion in Kyrgyzstan has achieved self-sufficiency in some areas.Kyrgyz sugar farmers suffer from foreign imports – Agroberichten Buitenland

Scaling to 50,000-100,000 ha could cover 50-70% of the region’s 2.18 million tons annual sugar needs, with Kazakhstan’s 2024 harvest exceeding 1.5 million tons.Kazakhstan’s Record Sugar Beet Harvest – Times of Central Asia

2. Sweet Sorghum (Sorghum bicolor)

Adapted to arid continental climates, sweet sorghum tolerates salinity and requires only 300-500 mm water, ideal for Uzbekistan’s sierozems.Planning Spatial Layout of a Typical Salt Tolerant Forage of Sweet Sorghum – PMC

As a 90-120 day annual, it avoids frosts and yields 3-7 tons/ha of syrup (2-4 tons/ha sugar equivalent).Sweet Sorghum : an alternative energy crop – CORDIS

Success in similar drylands suggests viability in southern Kyrgyzstan.SWEET SORGHUM (SORGHUM BICOLOR (L.) MOENCH) – SABRAO Journal

Piloting on 20,000-30,000 ha could displace 10-20% of imports, with multifunctional uses for forage and bioenergy.Sweet Sorghum: From Theory to Practice – ICRISAT

3. Jerusalem Artichoke (Helianthus tuberosus)

This perennial suits cold climates, surviving -30°C winters in chernozems, with 400-600 mm water needs.Jerusalem Artichoke: Nitrogen Fertilization Strategy and Energy Balance – MDPI

Yields 20-40 tons/ha of tubers with 15-20% inulin, a low-calorie sweetener.Tuber and Inulin production of Jerusalem artichoke – USDA ARS

Promising in Turkmenistan for biotechnology.Inulin content of Jerusalem artichoke – Crop Journal

It could cover 5-10% of needs, especially in health products.Responses of inulin content and inulin yield of Jerusalem artichoke – IJPP

4. Chicory (Cichorium intybus)

Suitable for temperate arid areas with well-drained loams (pH 5.5-7.0) and 500-700 mm water.Chicory – an overview – ScienceDirect

Roots yield 40-60 tons/ha with 40-50% inulin.Potential Expansion of Root Chicory Cultivation Areas in Chile – ResearchGate

It could substitute 5-15% in functional foods.A case study of root chicory for inulin production – CHIC Project

5. Date Palm (Phoenix dactylifera)

Limited to southern hot oases with saline sands and irrigation, tolerating brief -10°C.Production suitability of date palm under changing climate – JKSUS

Trees yield 50-100 kg/year of fruits (65-80% sugars).The Date Palm (Phoenix dactylifera L.) – ASHS Journals Grown in Turkmenistan oases.CHAPTER IV: CLIMATIC REQUIREMENTS OF DATE PALM – FAO

Processing into sugar could add 5-10% supply.Assessment of farmers practices to date palm soil fertilization – PMC

Conclusion

These crops offer pathways to greater sugar self-sufficiency, but success requires regional collaboration. The best option in all cases for Central Asia is to stick together, be it food security or anything else, through shared irrigation projects, seed banks, and trade policies to mitigate vulnerabilities. ///nCa, 14 January 2026
