Indonesia’s demographic dynamics marked by shifts in age structure, accelerating urbanization, and shrinking household sizes are fundamentally reshaping national food demand and consumption patterns.
This was conveyed by Prof Ekawati Sri Wahyuni, Professor of Demography and Population Studies at the Faculty of Human Ecology, IPB University.
In her Scientific Oration as Professor at IPB University on Saturday (2/14), she outlined three major demographic drivers that are accelerating the transformation of the national food system.
The first factor is the shift in age structure resulting from declining fertility and mortality rates. This transition is projected to produce a demographic dividend peak between 2030–2040, while simultaneously increasing the proportion of elderly people in the population.
“In food choices, generational taste differences shaped by rising welfare levels are evident in changing dietary patterns,” she explained.
Rice and cereal consumption is gradually shifting toward higher-value foods such as animal protein, fruits, and vegetables. At the same time, there is an increase in the consumption of calorie-dense foods such as sugar, reflecting what is commonly known as the nutrition transition.
The second factor is urbanization, which encourages greater diversity in food consumption, including imported food commodities that are not domestically produced.
“This growing dependence on external sources increases vulnerability to global supply chain disruptions and price fluctuations,” she stated.
At the same time, disparities in regional development have contributed to the phenomenon of the double burden of malnutrition where undernutrition and overnutrition coexist within the same population.
The third factor is the reduction in household size combined with increased female participation in the public sector, which has altered household economic dynamics.
“This is reflected, for example, in the shift in food provision patterns toward fast food and ready-to-eat meals,” she added.
She emphasized the importance of a population data based approach in understanding the transformation of food demand and consumption.
“This is necessary to ensure that emerging opportunities can be utilized, while also addressing food and nutrition challenges and adapting to distribution changes and shifting consumer behavior,” she said.
Prok Ekawati also highlighted Indonesia’s current food self-sufficiency dilemma. Commodities such as wheat used for noodles and bread are entirely imported, while domestic beef production remains below national demand.
“The shift in consumer preferences toward non-tropical products increases vulnerability to global price fluctuations and geopolitical dynamics,” she explained.
Nevertheless, she offered a pragmatic policy approach for the government.
“Food self-sufficiency must be evaluated pragmatically by balancing domestic production with strategic imports for commodities that are difficult to cultivate locally,” she asserted.
The growing trend toward healthy lifestyles also opens market opportunities for organic products, plant-based alternatives, and functional foods targeting the middle class. This is further supported by food technology innovations, including environmentally friendly packaging and cold-chain logistics systems.
In response to this demographic transition, the private sector is encouraged to diversify and segment products specifically for the elderly considering texture and nutritional content as well as for single person households through smaller packaging formats.
“Strengthening presence in e-commerce platforms and implementing digital marketing strategies relevant to Generation Z are also crucial,” Prof Ekawati concluded. (MW) (IAAS/FHD)
