Sustainable and Healthy Diets: A Chat with WWF’s Brent Loken

WWF, renowned for its iconic panda emblem, stands as the world’s largest conservation organization. Traditionally, WWF’s mission centred on preserving iconic species like pandas, tigers, and elephants. However, the organization has now broadened its scope to tackle systemic issues, particularly those contributing to biodiversity loss and deforestation, with a significant focus on food systems as a driving force.

In this episode, we engage with Brent Loken, the Global Food Lead Scientist at WWF, as he delves into the intricate world of food systems’ impact. Loken’s role spans nearly 100 countries, where he oversees food-related scientific endeavors, emphasizing the connection between research and actionable solutions while respecting global culinary traditions.

Brent offers a pragmatic approach to food choices, advocating for more plant-based foods, reduced animal products, whole grains, and less sugar, accompanied by adequate hydration with water. His key advice is to avoid overwhelming consumers with complex dietary labels and instead provide clear, manageable recommendations that make healthier and more sustainable choices appealing through affordability and effective marketing. While supporting the benefits of local food in specific contexts, Brent stresses the carbon footprint of shipping food often pales in comparison to the significance of other choices, such as adopting plant-based diets. Food systems are complex puzzles, and tailored solutions are essential.

The conversation also addresses the critical role of research in engaging policymakers and the public to drive transformative change in food systems. WWF’s mission extends beyond research, aiming to simplify complex issues and make scientific findings pertinent to policymakers, empowering them to craft effective policies and regulations benefiting both people and the planet.

Loken’s journey into food-related research was sparked while collaborating with Indonesian communities, revealing the profound interplay between conservation and food systems. He now brings this knowledge to us through this episode, where he also highlights the need for more discussions on sustainable diets. So, as you listen to this episode, we encourage you to think about  which of these topics will you be bringing to the dining table!

Why Regenerative Agriculture makes business sense

#308 | December 2025

What if the future of farming was not only better for biodiversity and soil health, but also a smarter long-term investment? In this episode of What The Field?!, we sit down with Alessia Lenders, Head of Impact at SLM Partners, a pioneering investment firm proving that ecological farming and solid financial performance can go hand in hand. Alessia’s journey into regenerative agriculture did not begin in the fields but in the world of traditional finance. Searching for investment solutions that could genuinely improve biodiversity, she found herself returning again and again to agriculture: one of the biggest drivers of environmental degradation, but also one of the greatest opportunities for change. Today, SLM Partners manages more than 760 million dollars in farmland and forestland across the United States, Australia and Europe. Their approach is simple yet radical: invest in land, partner with skilled farmers, and scale regenerative systems that rebuild soil, protect water and secure long-term productivity. What you will discover in this episode 1. The economic logic behind regenerative agriculture Alessia explains why long-term, patient capital fits naturally with regenerative transitions: healthier soils, more diverse revenue streams (including carbon projects in Australia) and more climate-resilient farms. Far from being a financial compromise, regenerative systems can improve profitability by reducing input costs, stabilising yields and tapping into premium and organic markets. 2. Why investors are turning to farmland Farmland behaves differently from stocks and bonds, which makes it an attractive diversifier for institutional investors. SLM adds another layer: regenerative farms that can outperform conventional systems over the long term while delivering measurable environmental impact. 3. The crucial role of the farmer SLM’s model is farmer first. They partner with experienced growers who want to expand but lack the capital to acquire land. SLM buys the land, the farmer manages it and both commit to a regenerative transition adapted to local realities. The result is a partnership that supports young farmers, protects landscapes and proves that ecological agriculture can scale. 4. A clearer picture through data From soil microbiology to water modelling, biodiversity indicators and carbon estimates, SLM collects an extraordinary amount of data to understand and communicate how landscapes change over time. This allows them to build business models that anticipate droughts, evaluate water security and verify real ecological outcomes. 5. Regenerative agriculture is not one size fits all Whether transitioning almond orchards in Spain, grasslands in Australia or mixed farms in the United States, SLM adapts regenerative principles to each context. For some farms, the target is organic certification. For others, it is a regenerative outcome-based approach focused on soil health, biodiversity and long-term resilience. This episode goes deeper than we ever have into the financial mechanics behind regenerative agriculture. It is a rare look at how capital, ecology and farming come together to build food systems that work for both people and the planet. If you have ever wondered whether regenerative agriculture really adds up financially, ecologically or both, this is the conversation you will not want to miss.
