Environmental plantings are no longer just about carbon offsets. When integrated into farm systems, they can stack returns: carbon, biodiversity, productivity, and resilience. Here, Hugh Killen explains how the right design can turn ecological restoration into return.

California’s Central Valley, which produces 98% of the world’s almonds, is implementing water reforms that could reshape food production – rippling across global supply chains, and creating opportunities for Australian markets and investors.

Picture our soil as a bucket that holds carbon, and every season, we’re either topping it up (and hopefully, holding a bit more) or watching it leak. For a long time, Australian agriculture was carrying buckets with holes in the bottom. Centuries of cultivation, erosion, and overgrazing stripped away the organic matter (of which ~58% is carbon) that once acted like a sponge – holding water, feeding crops and microbes, and storing carbon.

As scientists, we’re trained to reduce complex systems into clear, measurable questions: it’s how we understand problems, test assumptions, and design solutions. But when you take scientific findings beyond the lab and into the paddock, things get more interesting! Agriculture doesn’t operate in isolation. Soils, seasons, crops, livestock and human decisions all interact dynamically.

Asset managers have a reputation for wanting everything cheap, cheaper, or free. It’s not entirely fair, but we’re not an open chequebook either. The business case has to stack up, whether we’re advising on a farm acquisition, investing in capital improvements, or evaluating an agtech tool. We’re asking: ‘Does it deliver value today?’ And perhaps more importantly, ‘Does it set us up for a more productive, profitable tomorrow?’

Australia’s carbon market is shifting gears. Voluntary markets have faltered amid criticism that they offer little more than a ‘license to pollute.’ Meanwhile, regulated demand is surging as big emitters, compelled by the Safeguard Mechanism, seek real climate solutions. That puts Australia’s land sector in the driving seat.
