March reminds us that our food choices ripple across ecosystems and communities in profound ways. It offers a unique chance to reflect on how the food we eat connects deeply with the health of our planet and the well-being of our communities.
Food rescue organisations stand at the intersection of these environmental and social imperatives
—redirecting perfectly good food from landfills not only prevents methane emissions and conserves the water, energy, and land used to produce that food, but also addresses hunger and inequality in our communities. When we rescue food, we're not just filling plates; we're protecting forests, preserving water, reducing waste, and building a more resilient food system where everyone has access to nutritious meals and our planet's resources are respected. This month highlights several important events that remind us food is more than just nourishment on our plates.

Seaweek and the Ocean’s Role in Feeding the Planet
Seaweek, celebrated from March 2 to 10, draws attention to the ocean’s critical role in global food security. Oceans provide a significant portion of the world’s protein through fisheries and aquaculture. They also support livelihoods for millions of people, especially in coastal communities.
Oceans supply about 20% of the animal protein consumed globally.
Sustainable fishing practices help maintain fish populations and protect marine biodiversity.
Healthy oceans regulate climate and support ecosystems that contribute to food production on land.
Protecting marine environments means safeguarding the future of food. Overfishing, pollution, and habitat destruction threaten this vital resource. By choosing sustainably sourced seafood and supporting ocean conservation, consumers can help maintain the balance.
Food Waste Action Week and New Zealand’s Food Rescue Movement
From March 18 to 24, Food Waste Action Week highlights efforts to reduce food waste and promote food rescue. In New Zealand, food rescue organizations collect surplus food from retailers, producers, and households, redirecting it to people in need.
Approximately one-third of all food produced globally is wasted.
Food waste contributes to methane emissions, a potent greenhouse gas.
Rescuing food saves resources like water, energy, and land used in food production.
Food rescue addresses hunger and reduces inequality by providing nutritious meals to vulnerable populations.
For example, organizations like Kaibosh in Wellington collect surplus food daily and distribute it to community groups. This not only prevents waste but also strengthens social ties and supports food security.
The International Day of Forests and Food Security
Forests play a crucial role in maintaining soil health and water cycles essential for agriculture. The International Day of Forests on March 21 reminds us that food security depends on healthy forests.
Forests prevent soil erosion, preserving fertile land for farming.
They regulate water flow, ensuring clean water reaches agricultural areas.
Forests provide habitat for pollinators and natural pest controllers.
Deforestation disrupts these services, leading to poorer crop yields and increased vulnerability to climate change. Protecting forests means protecting the foundation of our food systems.
World Water Day and Clean Watersheds for Agriculture
World Water Day on March 22 focuses on the importance of freshwater for life, including food production. Agriculture accounts for about 70% of global freshwater use, making clean water essential for growing crops and raising livestock.
Polluted water sources can harm crops and livestock health.
Efficient water use and watershed protection improve food production sustainability.
Community-led water management helps balance agricultural needs with ecosystem health.
For instance, riparian planting along waterways filters runoff and reduces sediment, improving water quality for farms downstream.
The International Day of Zero Waste and Rethinking Food Systems
On March 30, the International Day of Zero Waste challenges us to rethink how we produce, consume, and dispose of food. A zero waste approach aims to minimize waste generation and maximize resource use.
Reducing packaging and food waste lowers environmental impact.
Composting food scraps returns nutrients to the soil.
Supporting local food systems cuts transportation emissions and strengthens communities.
Zero waste food systems require collaboration among producers, retailers, consumers, and policymakers to create lasting change.
Food Rescue Organizations at the Intersection of Environment and Social Justice
Food rescue groups operate where environmental goals and social needs meet. By redirecting edible food from landfills, they reduce greenhouse gas emissions and conserve resources while feeding people who might otherwise go hungry.
Landfills produce methane as food decomposes anaerobically.
Rescuing food saves water, energy, and land used in production.
Providing food to those in need reduces inequality and builds community resilience.
These organizations demonstrate how simple actions can create ripple effects across ecosystems and society.
Practical Steps to Make a Difference This March
Everyone can contribute to healthier food systems and communities. Here are some practical ways to get involved:
Choose sustainably sourced seafood during Seaweek.
Support or volunteer with local food rescue organizations.
Reduce personal food waste by planning meals and storing food properly.
Advocate for forest and water protection policies.
Practice zero waste habits like composting and using reusable containers.
Small changes in daily habits add up to significant impacts when multiplied across communities.
