With the spring growing season well underway, gardeners have been busy sowing and growing their warm season crops and marvelling at nature’s transformation from slumber to supercharged! All this life-affirming growth in stark contrast to the various crises of the 21st century that threaten our food security. Interest in alternative food-growing solutions is by necessity gaining traction. Climate change is causing unpredictable and erratic weather events, from droughts to floods and record heatwaves, bringing into question the resilience of both our conventional farming methods and the choice of crop varieties being grown.
As the world moves away from fossil fuels and the damaging carbon emissions they bring, our agricultural system remains dependent on both dirty, imported fuels and synthetic fertiliser derived from petrochemicals. Recent geopolitical events have exposed the vulnerability of industrial agriculture and added a sense of urgency.
Amongst the solutions being discussed are alternative fertiliser sources, organic farming and hydroponic systems, all of which have potential to produce food in a cleaner, more sustainable way. Using hydroponics for example, we can produce vegetables in up to half the time, using a fraction of the water and energy required in traditional farming.
Perhaps the problem is greater than efficiency and resources though. Even hydroponics or large-scale organics separate people from their food production. Modern hybrid seed varieties, owned and controlled by big corporations, deprive the public of their human horticultural heritage – the fantastic diversity and variety of open pollinated heirloom seeds. If we are to truly secure our food supply and meet the challenges of climate change, protecting and unlocking the diversity within heirlooms is essential. Saving seed in our own gardens on a local level allows us to adapt our crops to climatic changes and our own tastes, soils and conditions. Public ownership of our seed puts control back into the hands of gardeners.
It is difficult to quantify the benefits of homegrown food. Heirloom vegies picked a short walk from the kitchen speak for themselves in quality, freshness and taste. The satisfaction of growing them from a tiny seed to our dinner plate contrasts sharply with supermarket food grown miles from its destination. Growing food at home lets us adapt and meet challenges, which large-scale production cannot do. A resilient, sustainable food supply requires action on a local scale: growing our own, keeping heirlooms alive and sharing with other gardeners.
