The second Sustainable Development Goal (SDG 2) — Zero Hunger — aims to end hunger, achieve food security, improve nutrition, and promote sustainable agriculture by 2030. Despite advancements in agricultural technology and food production, hunger and malnutrition continue to affect hundreds of millions of people worldwide. According to the United Nations Food and Agriculture Organization (FAO), over 735 million people faced chronic hunger in 2023. The persistence of hunger is not merely a result of food scarcity, but of inequality, poverty, conflict, and unsustainable agricultural practices. SDG 2 recognizes that ending hunger requires transforming global food systems to ensure that everyone, everywhere, has access to sufficient, safe, and nutritious food all year round.
Understanding Hunger and Food Insecurity
Hunger is defined as the condition in which a person is unable to consume enough calories to maintain a normal, active, and healthy life. However, hunger is only one aspect of food insecurity. Food insecurity occurs when people lack reliable access to affordable, nutritious food. It is influenced by factors such as poverty, inflation, conflicts, climate change, and weak agricultural infrastructure.
Malnutrition—another critical component of SDG 2—refers to deficiencies, excesses, or imbalances in a person’s intake of nutrients. Malnutrition manifests in various forms, including undernutrition, micronutrient deficiencies, and obesity. Alarmingly, these conditions can coexist within the same population, household, or even individual.
The world currently faces a “triple burden of malnutrition”—hunger, nutrient deficiencies, and rising obesity rates—driven by unhealthy diets and inequitable food systems.
Targets of SDG 2
SDG 2 encompasses several interconnected targets that guide global action toward ending hunger and achieving food security:
- End hunger and ensure access to safe, nutritious, and sufficient food for all people, particularly the poor and vulnerable, including infants, throughout the year.
- End all forms of malnutrition by 2025, including achieving internationally agreed targets on stunting and wasting in children under five years of age, and address the nutritional needs of adolescent girls, pregnant and lactating women, and older persons.
- Double the agricultural productivity and incomes of small-scale food producers, particularly women, indigenous peoples, family farmers, and fishers, through secure access to land, resources, and technology.
- Ensure sustainable food production systems and implement resilient agricultural practices that increase productivity, maintain ecosystems, and adapt to climate change.
- Maintain the genetic diversity of seeds, cultivated plants, and domesticated animals, and promote fair and equitable sharing of the benefits from their use.
- Increase investment in rural infrastructure, agricultural research, and technology development to enhance productivity and reduce hunger.
These targets collectively aim to create a food system that is inclusive, sustainable, and resilient to crises.
Global Progress and Emerging Challenges
Over the past few decades, the world has made considerable progress in reducing hunger, largely due to improvements in agricultural productivity and economic growth. However, the pace of progress has slowed—and even reversed in some regions.
The COVID-19 pandemic, climate change, armed conflicts, and economic instability have intensified food insecurity worldwide. For example, disruptions in global supply chains and rising food prices have pushed millions into hunger. Additionally, prolonged droughts, floods, and other climate-related disasters have affected crop yields, livestock, and fisheries, particularly in developing countries that depend heavily on agriculture for livelihoods.
The FAO’s 2023 report warns that without transformative action, the world will fall far short of achieving Zero Hunger by 2030. Sub-Saharan Africa and South Asia remain the regions most affected by chronic food insecurity and malnutrition.
Strategies for Achieving Zero Hunger
- Sustainable Agriculture and Food Systems
Transitioning to sustainable agricultural practices is essential to ensure food security without depleting natural resources. Agroecology, crop diversification, organic farming, and precision agriculture can improve soil health, water efficiency, and biodiversity while maintaining high productivity. - Empowering Smallholder Farmers
Small-scale farmers produce nearly one-third of the world’s food, yet many live in poverty. Providing access to land, markets, finance, and agricultural technology can boost productivity and income. Women farmers, who constitute a large share of agricultural workers, should be given equal rights and opportunities. - Nutrition-Sensitive Policies
Governments and institutions should integrate nutrition goals into agricultural and health policies. This includes fortifying foods with essential micronutrients, promoting breastfeeding, and encouraging diverse diets that include fruits, vegetables, and proteins. - Reducing Food Waste and Loss
Approximately one-third of all food produced globally is wasted each year. Reducing food waste through better storage, transport, and consumer awareness can significantly enhance food availability and environmental sustainability. - Resilience to Climate Change
Climate-smart agriculture (CSA) offers strategies to help farmers adapt to changing weather patterns. Investments in research, early warning systems, and water management can strengthen resilience to droughts and floods. - Global Partnerships and Investments
Achieving Zero Hunger requires international cooperation. Partnerships among governments, international organizations, private sectors, and civil society are crucial to mobilize resources, share technology, and implement effective policies.
Case Studies and Best Practices
Countries like Brazil and Ethiopia have demonstrated that well-designed public policies can drastically reduce hunger. Brazil’s “Fome Zero” (Zero Hunger) program combined social protection, school feeding, and support for smallholder farmers, reducing hunger and poverty levels significantly. Similarly, Ethiopia’s Productive Safety Net Programme (PSNP) has helped rural households build resilience to food insecurity through public works and livelihood support.
The Way Forward
To realize the vision of SDG 2 by 2030, global food systems must undergo a fundamental transformation—one that prioritizes equity, sustainability, and human well-being over profit and exploitation. Governments must integrate food security into national policies, while private sectors can play a role in sustainable food production, value-chain transparency, and reducing waste.
Moreover, education and awareness are vital. Citizens must understand the environmental and social impact of their food choices and advocate for sustainable consumption patterns.
Conclusion
The goal of Zero Hunger represents humanity’s collective commitment to ensuring that no one goes to bed hungry. Ending hunger is not only about producing more food but ensuring fair access, nutritious diets, and resilient food systems. It calls for coordinated global action—combining science, policy, innovation, and compassion.
As the 2030 deadline approaches, achieving SDG 2 remains both a challenge and an opportunity: a challenge to address the structural roots of hunger and inequality, and an opportunity to build a more just, sustainable, and nourished world for all.
