Sugarcane vs Sugar Beet: Pakistan's Sugar Economy

When you stir sugar into your morning tea or enjoy a sweet treat, you are consuming the final product of a long agricultural journey that begins in Pakistan’s fields. For decades, sugarcane has dominated the country’s sugar industry, but a quieter contender, sugar beet, is increasingly attracting attention. As Pakistan confronts worsening water scarcity, rising temperatures, and growing pressure on agricultural resources, an important question is emerging: should the country continue relying heavily on water-intensive sugarcane, or should it expand the role of faster-maturing, more water-efficient sugar beet?

The answer is far more complicated than simply choosing the crop that uses less water. Sugarcane is deeply embedded in Pakistan’s agricultural economy. During 2023–24, farmers cultivated more than one million hectares of sugarcane and produced approximately 87.60 million tonnes of cane. The crop supplied around 90 sugar mills and generated 6.76 million tonnes of sugar, accounting for nearly 99 percent of national sugar production. Sugarcane also contributes about 3.2 percent to agricultural value addition and 0.8 percent to GDP. It supports millions of farmers, farm workers, transporters, mill employees, and businesses throughout the value chain.

Sugar beet, by comparison, remains a minor crop. In 2023-24, it occupied just over 6,000 hectares and contributed approximately 0.08 million tonnes of sugar, or only 1.18 percent of national production. Yet its relatively small footprint may conceal an important opportunity for a water-stressed country.

The strongest argument for sugar beet is water. Sugarcane has a long growing cycle of roughly 10–14 months and may require around 64–100 acre-inches of irrigation water, depending on planting time and local conditions. Sugar beet matures in approximately four to five months and requires about 27 acre-inches. This shorter growing period and lower irrigation requirement could make beet particularly attractive in areas where groundwater is declining and irrigation water is becoming increasingly expensive.

At first glance, the choice appears obvious: sugar beet seems to win the water-efficiency contest. But agriculture is not decided by water requirements alone. Farmers must also consider yields, profitability, market access, processing infrastructure, harvesting costs, mill compatibility, contracts, by-products, and the reliability of returns. The real question for Pakistan, therefore, is not whether sugar beet can replace sugarcane overnight, but whether a more balanced sugar economy could produce the sugar Pakistan needs while using its increasingly scarce water resources more wisely.

Why Sugarcane Won’t Be Dethroned Easily

Despite sugar beet’s lower water requirement and shorter growing season, replacing sugarcane across Pakistan would be neither simple nor necessarily desirable. Sugarcane is deeply embedded in the country’s agricultural, industrial, and rural economy, while its production system has evolved over decades around Pakistan’s climate, infrastructure, markets, and farming traditions. The question, therefore, is less about dethroning sugarcane and more about finding where sugar beet can complement it.

Climate is the first major constraint. Pakistan’s principal agricultural regions lie largely in subtropical, arid and semi-arid environments where sugarcane has adapted well to local conditions. Sugar beet, by contrast, is fundamentally a temperate crop and performs best under cooler conditions. It has demonstrated potential in parts of Khyber Pakhtunkhwa and Punjab, including areas such as Attock and Sargodha, and research by PARC and the National Sugar and Tropical Horticulture Research Institute has also indicated opportunities in lower Sindh. Nevertheless, its suitability varies considerably across the country. Rather than replacing sugarcane everywhere, sugar beet is more realistically viewed as a complementary crop for suitable agroecological zones.

Infrastructure presents another formidable barrier. Pakistan’s sugar industry has involved billions of rupees in investment, with dozens of mills specifically designed around sugarcane crushing, juice extraction, and processing. Sugar beet requires different processing arrangements, including root washing, slicing, diffusion, and specialized handling and storage. Converting existing facilities would therefore require substantial capital investment and technological restructuring. Given Pakistan’s financial constraints, a wholesale transition would be difficult to justify economically.

Sugarcane also offers an important advantage that is often overlooked: bagasse. During the 2023-24 season, Pakistan’s sugar mills generated roughly 29 million tonnes of this fibrous residue. Far from being waste, bagasse is a valuable source of energy. Mills use it to generate steam and electricity for their operations, while some cogeneration facilities can supply surplus electricity to the grid. Bagasse also supports industries producing paper, board, packaging materials, furfural, silica, and other value-added products. Sugar beet does not provide an equivalent fibrous residue, potentially leaving beet-processing facilities more dependent on commercial energy sources.

Sugarcane is also closely connected to Pakistan’s rural traditions and informal economy. An estimated 15-25 percent of cane production is used for gur, supporting thousands of small processing units and rural households. Sugarcane juice remains a popular seasonal beverage, while gandheri provides an inexpensive and widely enjoyed snack. These activities generate employment and income beyond the formal sugar industry, benefits that cannot easily be captured in conventional crop comparisons.

Finally, sugarcane has a major agronomic advantage through ratooning. After the initial crop is harvested, new shoots can develop from the remaining root system, allowing farmers to obtain subsequent crops without complete replanting. Ratoon cultivation reportedly covers more than half of Pakistan’s sugarcane area and can reduce establishment and operational costs substantially. Sugar beet, as an annual root crop, does not offer this advantage.

For all these reasons, sugarcane is unlikely to be dethroned quickly. The smarter strategy may be diversification rather than replacement expanding sugar beet where its water savings and agroecological suitability offer genuine advantages while preserving the economic ecosystem built around sugarcane.

Why Pakistan Needs Both Sugarcane and Sugar Beet

Sugarcane has another important advantage that deserves greater attention as Pakistan prepares for a warmer and more water-stressed future: its C4 photosynthetic pathway. C4 plants have evolved a highly efficient mechanism for capturing carbon dioxide while limiting losses associated with photorespiration. This allows them to maintain relatively high photosynthetic productivity under conditions of intense heat and strong sunlight, often with greater water-use efficiency than C3 crops.

Sugar beet, by contrast, is a C3 plant and generally performs best under cooler conditions. This does not make it unsuitable for Pakistan, but it means that its comparative advantage is likely to be concentrated in specific regions and growing seasons rather than across the entire country. As temperatures rise, the ecological suitability of different crops will become increasingly important in determining where each crop should be grown.

Pakistan therefore does not need a winner-takes-all strategy. The more sensible approach is to develop a complementary sugar system in which sugarcane remains the dominant crop in areas where its climate, established infrastructure, and economic returns make it appropriate, while sugar beet expands selectively in regions where its shorter growing cycle and lower water requirement provide clear advantages.

For sugarcane, the priority should be climate-smart intensification rather than unrestricted expansion. Agricultural research institutions should develop varieties with greater water-use efficiency, drought tolerance, heat resilience, disease resistance, and improved sugar recovery. Precision irrigation, drip systems, fertigation, laser land levelling, soil-moisture sensors, and digital irrigation scheduling can help farmers produce more sugar with less water. Better agronomic management of ratoon crops could further reduce production costs and improve resource efficiency.

Sugar beet, meanwhile, should be promoted through carefully targeted regional programs. Farmers in agroecologically suitable areas need access to quality seed, technical guidance, reliable buyers, and appropriate processing facilities. Expansion should follow market and resource conditions rather than political targets.

Pakistan should also capture more value from sugarcane's considerable energy potential. Expanding efficient bagasse-based cogeneration could reduce dependence on fossil fuels while providing an additional revenue stream for sugar mills. Research into bagasse-based packaging, biochemicals, bioenergy, and other value-added products could further strengthen the sugar industry's contribution to the circular economy.

Ultimately, the goal should not be to declare sugarcane or sugar beet the winner. Pakistan needs the right crop in the right place, supported by the right technology and incentives. In a country where water scarcity is becoming a defining agricultural constraint, smarter crop allocation, climate-resilient sugarcane, selective sugar beet expansion, and better use of agricultural by-products can create a sugar sector that is simultaneously more productive, resource-efficient, and resilient.

Conclusion

Pakistan’s sugar debate should not be framed as a simple contest between sugarcane and sugar beet. Sugarcane will remain central to the country’s sugar economy because of its climatic adaptability, established processing infrastructure, ratoon potential, rural employment, and valuable bagasse-based energy and by-products. Yet its heavy water requirements make continued expansion increasingly difficult to justify in water-stressed regions. Sugar beet offers an important complementary option, particularly where cooler conditions, shorter growing seasons, and limited irrigation availability provide a comparative advantage. The way forward is therefore diversification, regional specialization, and climate-smart production rather than wholesale replacement. Pakistan should identify areas where sugar beet can genuinely conserve water and generate competitive returns while improving sugarcane’s water-use efficiency through better varieties, precision irrigation, improved agronomy, and digital technologies. At the same time, greater value should be extracted from sugarcane by-products such as bagasse. Ultimately, Pakistan needs to produce sugar with fewer natural resources. The objective should be a more efficient, resilient, and economically sustainable sugar sector in which the right crop is grown in the right place with the right technology.
