Water stewardship drives sustainability gains for Woolworths’ fresh produce suppliers
In an era where climate change threatens agricultural productivity and food security across southern Africa, water management has emerged as a critical frontline in the battle for sustainable farming. A groundbreaking four-year PhD study conducted by Zimbabwean researcher Catherine Mazhandu at Coventry University has delivered a rare independent evaluation of Woolworths South Africa’s Farming for the Future programme, revealing encouraging environmental progress among the retailer’s fresh produce suppliers.
Access to 16 years of detailed environmental performance data, 68 producer surveys, interviews, and extensive farm visits granted Mazhandu a unique insight into how long-term collaboration between retailer and farmers fosters resilience against droughts, floods, and external shocks like the COVID-19 pandemic, all while supporting the consistent production of high-quality fresh produce.
Putting water management first
Among the numerous environmental pillars studied — including soil health, biodiversity, pest control, waste management, fertiliser use, and carbon footprint — irrigation and water management emerged as the most rapidly improving area. Farmers engaged in Farming for the Future typically experience an initial adjustment period lasting around four years, during which performance may temporarily dip. However, those who commit to long-term transformations reap steady advancements, especially in water stewardship.
“Irrigation and water management is a critical priority,” Mazhandu emphasised during a Woolworths-hosted webinar on 16 March 2026. “After five years, there is a consistent improvement for producers in this area.” The willingness of suppliers to make early investments and operational changes here speaks volumes about the tangible cost and operational benefits that water-saving innovations provide.
Soil gains require patience and faith
In contrast, gains in soil health and biodiversity unfold more gradually. These improvements require sustained ecological restoration efforts over a decade or more, with Mazhandu noting that “soil varies significantly for each producer and is based on external factors.” Nevertheless, positive trends in soil structure, moisture retention, and organic carbon content strengthen climate resilience and food security in the long term.
“Soil has historically been one of the most ignored components in science, and now it is getting the attention it deserves,” said Mazhandu, reflecting a global scientific movement recognising the critical role healthy soils play in sustainable food systems.
Diverse crops, diverse journeys
Environmental performance does not improve equally across all crop types. Fruit producers, for example, show a 5% faster rate of environmental progress compared to vegetable and salad farmers. This variation underlines the importance of tailoring training, best practice sharing, and implementation support to each crop sector’s unique challenges and opportunities.
Farmers handling multiple crops and navigating several retailer standards often display greater innovation readiness, adapting practices quickly due to experience with regulatory complexity. This agility improves overall environmental outcomes while balancing supply chain demands.
A collaborative model built on shared investment and knowledge
The success of Farming for the Future rests on more than just environmental targets. A key pillar is bringing farmers into networks of knowledge sharing and providing ongoing access to the latest agronomic information. As Mazhandu put it, “Farmers are always looking for information. Farming for the Future gives them the chance to tap into current industry practices and networking opportunities.”
Crucially, the programme is built around shared investment between Woolworths and its suppliers — contrasting global certifications that often place the financial burden entirely on producers. This mutual accountability fosters trust, increases engagement, and sustains long-term environmental commitments.
Kobus Pienaar, technical manager at Woolworths Food, affirmed this in a media statement: “Farming for the Future supports environmental sustainability and supply stability. It restores soil health, improves water management, protects biodiversity, and helps suppliers recover faster from climate shocks while maintaining product quality.”
Zimbabwean farmers leading local water stewardship efforts
Zimbabwe is no stranger to the cyclical challenges of erratic rainfall and water scarcity that shape southern Africa’s farming landscape. Local initiatives resonate strongly with lessons from Woolworths’ programme. For instance, farmer Miriam Nyoni from Mashonaland East Province has embraced innovative drip irrigation systems and rainwater harvesting techniques to maximise water efficiency on her horticultural plot.
“Investing in water management has allowed me to grow tomatoes through dry spells without compromising yield,” Miriam shared. Her experience reflects a growing cadre of Zimbabwean producers aligning with the national Zimbabwe Agenda for Sustainable Socio-Economic Transformation (ZimAsset) framework, which prioritises sustainable agriculture and climate resilience as pillars of national development.
Furthermore, government extension services actively promote water-smart agriculture through training modules on irrigation scheduling, drought-resistant crop varieties, and soil moisture conservation methods, creating fertile ground for scaling proven strategies gleaned from regional success stories like Farming for the Future.
Lessons for policy and farmer practice
As Zimbabwe navigates towards its National Development Strategy 1 (NDS1), integrating long-term, science-based sustainability initiatives is vital. Collaborative models that blend public, private, and farmer partnerships hold substantial promise for building resilience while increasing productivity.
Key takeaways for Zimbabwean policymakers, agricultural extension agents, and farmers include:
- Prioritising water efficiency as a foundational element of climate-smart agriculture
- Encouraging shared investment models between buyers, suppliers, and government to reduce financial barriers
- Building technical capacity and information networks enabling farmers to adopt innovative practices
- Recognising different crops and regions require tailored approaches for maximal impact
- Investing in long-term soil health restoration as a critical but gradual process
The road ahead
Catherine Mazhandu’s research underlines that sustainability in agriculture is a marathon, not a sprint. Environmental improvements require patience, collaboration, and consistent commitment beyond short-term shocks or crises. For Zimbabwe’s farming communities confronting climate challenges, the journey mapped by Woolworths’ Farming for the Future programme offers vital lessons and a hopeful blueprint.
By embracing water stewardship and regenerative farming methods alongside meaningful partnerships, Zimbabwean producers can strengthen their resilience, uplift livelihoods, and contribute decisively to national food security goals.
With the momentum from independent research and real-world examples lighting the way, the future for Zimbabwe’s farmers looks not only sustainable but bright.
