How to Increase Food Security

Food security is becoming one of the most urgent global challenges of our time. As populations grow, climates shift, and resources tighten, countries across Africa and the world are under pressure to secure reliable access to fresh, nutritious food. Today, improving food security isn’t simply about producing more food—it’s about producing it smarter, faster, and more sustainably. In this article, we explore how to increase food security using modern farming, advanced technology, and smarter supply-chain strategies—while highlighting the powerful impact of Drylands’ climate-smart approach.

Understanding the Four Pillars of Food Security

Before diving into solutions, it’s important to understand the framework that shapes global food policy. Food security has four core pillars:

1. Availability

There must be enough food produced consistently and sustainably.

2. Accessibility

People must be able to afford it and physically reach it.

3. Utilisation

Food must be nutritious, safe, and properly stored or preserved.

4. Stability

Supply must remain reliable throughout the year, despite climate, economic, or environmental changes.

Any effective strategy for improving food security needs to strengthen all four.

Do you really know: What Is Food Security? Everything You Need to Know

Increasing Food Production Through Climate-Smart Agriculture

1. High-Tech Greenhouse Farming

Traditional farming is vulnerable to droughts, extreme temperatures, pests, and poor soil. Climate-smart agriculture—especially Dutch-style glass greenhouses—removes these variables. Instead, you should be using:

• Climate-controlled greenhouses
• Hydroponic systems with near 100% water recirculation
• Renewable energy
• Precision irrigation and nutrient management

The result?
6–30× higher yields, year-round production, and consistent crop quality regardless of weather. This makes greenhouse production one of the fastest ways to strengthen national and local food security.

2. Hydroponics & Water-Efficient Crop Systems

Water scarcity is a major threat in emerging markets. Hydroponics solves this through:

• Up to 95% less water usage
• Minimal land requirements
• Faster crop cycles
• Safer, cleaner production

Hydroponic systems allow crops like tomatoes, cucumbers, peppers, leafy greens, and herbs to flourish even in regions where rainfall and soil conditions are unsuitable for conventional farming.

3. Climate-Resilient Crop Varieties

Improving food security also means growing crops that can survive heat, drought and unpredictable weather. High-yield, climate-resilient varieties ensure stable production—even under environmental stress.

4. Precision Farming & Smart Technology

Sensors, climate computers, and real-time monitoring systems allow farmers to:

• Reduce fertiliser and water waste
• Track plant growth accurately
• Optimise irrigation
• Prevent disease outbreaks early

This creates predictable harvests and pushes productivity to much higher levels.

Strengthening Supply Chains to Reduce Food Waste

Up to 30–50% of food in Africa is lost after harvesting due to poor storage, no cold chain, and long transport distances. Boosting food security requires both growing more food and wasting less of it.

1. On-Farm Cold Storage and Packing

Integrate cold rooms and packing facilities directly on the farm. This:

• Extends shelf life
• Reduces spoilage
• Improves food safety
• Cuts transport-related losses

With produce chilled, packed, and quality-checked at the source, communities receive fresher, safer food.

2. Shorter, Localised Supply Chains

Relying heavily on imported produce makes countries vulnerable to rising prices, border closures, and fuel costs. 

Short, efficient supply chains help stabilise prices and improve year-round access.

3. Value-Added Processing

Products like salad mixes, pre-packed vegetables, and portioned produce offer:

• Reduced food waste
• Extended shelf life
• Higher nutritional retention
• Affordable, convenient options for consumers

Processing on-site also creates new jobs and keeps value creation inside the community.

Do you know: How Will Climate Change Affect Food Security

Increasing Food Access and Affordability

1. Urban Agriculture & Vertical Farming

Cities can improve food security by using rooftops, unused buildings, and small urban plots to grow herbs, leafy greens, and vegetables. Combined with large-scale greenhouse farming, this creates a more resilient local food ecosystem.

2. Strengthening Local Markets & Distribution Points

Farmer markets, local retailers, and D2C services reduce costs, empower communities, and help close the gap between farm and table.

3. Education & Community Nutrition Programmes

Affordable access isn’t enough if nutrition knowledge is lacking. Community gardens, school feeding programmes, and awareness campaigns help families make better choices and reduce malnutrition.

How Drylands Help Increase Food Security

Drylands play a direct role in improving regional and national food security by delivering:

• High-tech greenhouse farms built on marginal land
• Hydroponic systems with ultra-efficient water use
• Year-round food production independent of climate
• Localised food distribution within hours of harvest
• Feasibility studies & investment plans for governments and private investors
• Project design, development, construction, and operations
• Training programmes that upskill local workforces

By combining technology, sustainability, and local empowerment, Drylands builds farms that protect communities from climate shocks and unpredictable supply chains.

Conclusion: How to Increase Food Security

Improving food security requires a holistic, forward-thinking approach—one that blends smart technology, sustainable agriculture, reliable supply chains, and supportive national policies. With climate change and population pressures intensifying, the world cannot depend on outdated farming methods alone. A secure food future is possible—and it starts with building smarter, more resilient, and more sustainable farming systems today.
