Hunger Remains Urgent as Populations Grow

SDG 2 aims to end hunger, achieve food security, improve nutrition, and promote sustainable agriculture by 2030. Yet the world remains far from this goal. In 2025, an estimated 645 million people—about 7.8 percent of the global population—experienced hunger, while around 2.1 billion people faced moderate or severe food insecurity.

Population growth adds pressure to already fragile food systems. More people require more food, clean water, farmland, jobs, and social services. The challenge is especially serious where populations are growing quickly while climate shocks, conflict, poverty, and inequality continue to disrupt food production and access. Zero hunger therefore requires action not only to produce more food, but to make food systems fairer, more resilient, and less wasteful.

Nutrition Must Keep Pace With Population Growth

Producing enough calories is not enough. People also need safe, diverse, and nutritious food, especially during early childhood. SDG Target 2.2 calls for ending all forms of malnutrition, including stunting and wasting among children under five, and addressing the nutritional needs of adolescent girls, pregnant and breastfeeding women, and older people.

The UN reports that rapid growth in the under-five population in some regions has offset improvements in reducing stunting and wasting. In sub-Saharan Africa, the under-five population grew by 20.3 percent between 2012 and 2024, making it harder for nutrition gains to keep pace. This means nutrition programs must be expanded quickly, particularly for mothers, infants, and young children, so that population growth does not erase hard-won progress.

Support Smallholder Farmers First

Smallholder farmers and family farms produce a large share of the world’s food, especially in developing regions. Yet many lack reliable access to land, credit, technology, irrigation, storage, and markets. The UN warns that public investment in agriculture is declining and that small-scale producers urgently need greater support, infrastructure, and technology for sustainable farming.

Investing in smallholder farmers is one of the fastest ways to improve food security. Better seeds, soil management, irrigation, climate information, storage facilities, and fair market access can raise productivity while strengthening local economies. The UN recommends pairing social protection and nutrition programs with productivity, climate adaptation, and decent-work measures for smallholder farmers.

Build Climate-Resilient Food Systems

Climate change is making hunger harder to solve. Droughts, floods, heatwaves, and unpredictable rainfall reduce harvests, damage livelihoods, and increase food prices. FAO notes that climate extremes are becoming more frequent and intense, affecting all dimensions of food security.

Immediate action should focus on climate-smart agriculture: drought-tolerant crops, efficient irrigation, soil restoration, agroforestry, and early-warning systems for farmers. The UN states that accelerating progress toward zero hunger requires resilient, climate-smart food systems, combined with adaptation measures for smallholder farmers. Food systems must be able to withstand shocks rather than collapse whenever weather patterns change.

Reduce Waste and Improve Access

The world does not face a simple shortage of food. It faces a problem of distribution, affordability, and waste. High food prices reduce purchasing power, while conflict and disrupted supply chains make food less available and more expensive. Nearly 60 percent of countries worldwide saw significant food-price increases due to conflict and disrupted supply chains.

Reducing food waste is an urgent priority. When food is wasted, the land, water, energy, labor, and transportation used to produce it are wasted too. At the same time, social protection programs, school meals, food assistance, and local food markets can help ensure that vulnerable households can access nutritious food. The UN emphasizes that food security requires a multidimensional approach, including social protection, safe and nutritious food, and food-system transformation.

Act Now, Together

Zero hunger cannot be achieved by agriculture alone. It requires coordinated action across farming, health, education, climate policy, trade, social protection, and peacebuilding. The UN calls for urgent, coordinated action to address inequality, transform food systems, invest in sustainable agriculture, and reduce the impact of conflict on food security.

Individuals can also contribute by wasting less food, supporting local farmers and markets, making sustainable food choices, and supporting good nutrition in their communities. These actions may seem small, but together they help shift demand toward fairer and more sustainable food systems.

With a growing population and increasing climate risks, the world cannot wait. The most urgent tasks are clear: protect children’s nutrition, support smallholder farmers, build climate resilience, reduce waste, and ensure that everyone can afford safe and nutritious food. These are not distant goals—they are immediate foundations for a future where no one is left hungry.
