How Climate-Smart Agriculture is Boosting Maize Yields in South Africa's North West Province

How Climate-Smart Agriculture is Boosting Maize Yields in South Africa's North West Province

In recent years, the agricultural landscape of South Africa’s North West province has faced significant challenges due to climate change. Small-scale farmers, who rely heavily on their crops for both subsistence and income, have been particularly affected by erratic weather patterns, including severe droughts and unpredictable rainfall. However, new research has shown that climate-smart agricultural practices can help these farmers increase their maize yields, improve food security, and contribute to environmental sustainability.

The Vulnerability of Small-Scale Farmers

Small-scale farmers in the North West province typically produce food for their own consumption, with some surplus sold in local markets. This makes them highly susceptible to the adverse effects of climate change, as their livelihoods and food supply depend directly on crop success. Traditional farming methods have become increasingly unreliable due to the region’s semi-arid climate, characterized by hot summers, mild winters, and inconsistent rainfall.

Adopting Climate-Smart Techniques

To combat these challenges, many farmers have begun adopting climate-smart agricultural techniques. These methods are designed to enhance resilience to climate change while improving crop productivity. Key techniques include:

Drought-Resistant Maize Seeds: New varieties of maize that can thrive in drought conditions have been introduced, ensuring a stable harvest even during periods of low rainfall.
Mulching: By covering the soil with organic material like leaves or bark, farmers can retain soil moisture, reduce erosion, and improve fertility.
Cover Cropping: Planting grasses or legumes between the main crops helps to nourish the soil and prevent weed growth, contributing to healthier crop development.
Mixed Cropping: Growing multiple crops together can help repel pests naturally, reducing the need for chemical pesticides.
Zero Tillage: This technique involves placing mulch over the soil and planting seeds directly into it, minimizing soil disturbance and preserving soil structure.

Positive Outcomes and Economic Benefits

The study, which surveyed over 300 small-scale maize farmers across 30 rural communities, found that approximately 86% of the farmers had adopted one or more climate-smart techniques. These farmers reported higher maize yields—about 6.2 tonnes per hectare compared to 3.9 tonnes per hectare for those using traditional methods. The increased productivity translated into higher incomes, with climate-smart farmers earning around R15,000 (US$824) per hectare annually, compared to R11,500 (US$632) for others.

This 30% improvement in income not only provides greater economic stability but also allows farmers to reinvest in their agricultural practices, thereby further enhancing their resilience to climate change.

Environmental and Social Impact

Beyond economic gains, climate-smart agriculture contributes to environmental sustainability. Techniques like cover cropping and zero tillage improve soil health, which in turn helps the soil retain water and supports better crop growth. Additionally, reducing the use of chemical inputs lowers greenhouse gas emissions and promotes biodiversity.

The adoption of these methods has also led to greater food security by diversifying crops and income sources, reducing the risk associated with relying on a single type of crop. This makes small-scale farmers more resilient to climate shocks and potential crop failures.

The Role of Government and Stakeholders

For climate-smart agriculture to be successful on a larger scale, support from the government and other stakeholders is crucial. Extension services that provide training and advice on climate-adaptive techniques can help farmers transition to more sustainable practices. Financial incentives and access to appropriate equipment are also necessary to encourage widespread adoption.

Strengthening agricultural co-operative societies will ensure that all small-scale farmers have the resources and support needed to implement climate-smart practices. Collaboration between academics, government departments, and farming communities is essential to develop new strategies and technologies that enhance agricultural productivity and resilience.

Conclusion

As climate change continues to pose a significant threat to food security and rural livelihoods, the adoption of climate-smart agriculture offers a viable solution. By integrating traditional knowledge with innovative techniques, small-scale farmers in South Africa’s North West province are paving the way for a more sustainable and resilient agricultural future.

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression Dinotefuran is known to negatively affect honeybee ( Apis mellifera ) behavior, but the underlying mechanism remains unclear. The magnetoreceptor ( MagR , which responds to magnetic fields) and cryptochrome ( Cry2 , which is sensitive to light) genes are considered to play important roles in honey bees’ homing and localization behaviors. Our study found that dinotefuran, even without direct contact, can act like a magnet, significantly altering MagR expression in honeybees. This non-contact exposure reduced the bees’ homing rate. In further experiments, we exposed foragers to light and magnetic fields, the MagR gene responded to magnetic fields only in the presence of light, with Cry 2 playing a key switching role in the magnetic field receptor mechanism ( MagR–Cry2 ). Yeast two-hybrid and BiFc assays confirmed an interactio...

Start the New Year Humming Like a Bee

Start the New Year Humming Like a Bee There are lots of opportunities to be as busy as a bee during these winter holidays. As we hustle toward the dawn of the New Year, it can be hard to notice that the natural world is actually suggesting something different for us right now. We’re past the solstice, but the winter still stretches ahead, the days are still short and the nights long. We’re being invited into a quieter, more inner-focused time. The ancient yogis were all about this inner focus. In India, for example, the Upanishads, the Sanskrit writings that accompanied the development of Hinduism — and alongside it, yoga — beginning around 800 B.C.E., went deeper than earlier texts had into philosophy and questions of being. With the goals of increased inner awareness and higher consciousness, yoga was at that time not yet as focused on the body or on asanas, as it now can tend to be. But the yogis did develop many practices to try to open the way to those goals. They discovered...

The Growing Dilemma of Pet Burials in South Korea: Environmental and Legal Hurdles

The Growing Dilemma of Pet Burials in South Korea: Environmental and Legal Hurdles As the number of pets in South Korea steadily increases, pet owners face a growing dilemma due to the limited number of pet cemeteries across the country. Under the current legal framework, pet remains are classified as household waste, requiring specific disposal methods that are neither convenient nor easily accessible for all citizens. The imbalance between the rising pet population—over 5.52 million households with pets by the end of 2022—and the mere 70 registered pet cemeteries has led to significant challenges. This shortage is particularly evident in regions like Jeju Island, where pet owners must undergo arduous journeys to the mainland to ensure their pets receive proper burials. The root cause of this shortage lies in the strict regulations governing the establishment of pet cemeteries. These facilities, which must include crematoriums, face numerous restrictions, such as proximity to resident...

Climate Crisis Claims Glacier's Vital Climate Data Archive

Climate Crisis Claims Glacier's Vital Climate Data Archive A recent study published in Nature Geoscience reveals a distressing consequence of global warming: the irreversible loss of valuable climate data stored in alpine glaciers. The research, conducted by a team led by Margit Schwikowski from the Paul Scherrer Institute (PSI), underscores the alarming rate at which glaciers are melting and highlights the implications for climate research. The study focuses on the Corbassière glacier at Grand Combin in Switzerland, where ice cores drilled in 2018 and 2020 were intended to serve as vital climate archives. However, comparing the two sets of ice cores reveals a grim reality—global warming has rendered the glacier unsuitable as a reliable climate archive. Glaciers, renowned as climate archives, encapsulate valuable information about past climatic conditions and atmospheric compositions. The fluctuating concentrations of trace substances in ice layers provide insights into historica...

German election: Climate and environment take a back seat

German election: Climate and environment take a back seat When the coalition government comprising the center-left Social Democratic Party (SPD) , Greens and neoliberal Free Democratic Party (FDP) emerged after the last German federal election in the fall of 2021, then-incoming Chancellor Olaf Scholz (SPD) did not object to being called the "climate chancellor." That was no surprise: the climate crisis had been a top issue during the election campaign. The new government made the fight against climate change a task for the Economy Ministry and appointed Vice Chancellor Robert Habeck from the Greens as its head. Three and a half years later, campaign speeches barely mention climate protection. The dominant issues are how to curb irregular immigration and how to boost Germany's sluggish economy.
