Monoculture farming involves growing only one crop type per time on a farm. Over the history of agriculture, this practice has played an immense role in food security. It has also shaped landscapes. However, it drives soil exhaustion and biodiversity depletion. The world’s population is growing rapidly. At the same time, the environment faces a growing number of challenges. Top of these include growing incidences of weather anomalies, pollution, and an increasingly depleting soil health. Despite all these, the demand for food on a global scale keeps rising. These issues have led to the need to take a closer look at the concept of monoculture. This article discusses the pros and cons of monoculture. It explores embracing a more diverse cropping system. This system requires low inputs and has minimal environmental impacts. We try to meet rising global food needs while making these changes.
Why Monoculture?
One of the greatest benefits of monoculture is that it allows for increased productivity and efficiency. Farmers choose crops that will thrive best in their local environment and hone down on them. An excellent example is rice cultivation in wetlands (marshy or fadama lands). Monoculture gives room for specialized production, increases profits, and cuts down on loss via mechanized and technologically managed farms. Furthermore, it provides for optimal utilization of space and crops.
The challenge with Monoculture.
Monoculture is applauded for its enormous contribution to food security. Nonetheless, it is necessary to equally note that there are several drawbacks. These are worth looking into and addressing. The most prominent are soil degradation and fertility loss. Too many of the same crop species are being cultivated continuously in the same field. This practice robs the soil of nutrients and essential balancing structures. Monocultured fields face significant pest and disease challenges. As a result, there is an over-dependence on high pesticides and insecticides. This reliance has far-reaching implications on soil health and the general ecosystem. Also important to mention is intensive use of fertilizers and water on monoculture farms, which is linked to all previous challenges mentioned. With rising cost of fertilizers globally this forces farmers into a corner, and consumers alike feels the impact.
How do we balance things out
The impacts of monoculture differ based on the environment and the intensity of farming. The overall idea is to embrace a more balanced approach to crop production. This approach is embodied in crop diversification and crop cycling.
In Sub-Saharan Africa, there is a lot to learn from small holder farmers. Their approach includes monocropping, double cropping, and mixed cropping. Their fields might be small in comparison to their mechanized colleagues. However, they manage to partition fields via separations of boundaries. They allow extensive room for meadows, which is vital for biodiversity to thrive. They use double cropping as a way of crop rotation. This method helps them cycle essential nutrients from legumes to cereal crops. This practice can substantially offset some negative impacts of monoculture. For example, disease and pest cycles are interrupted and the excessive dependence on fertilizers and agrochemicals is abated.
Pivoting toward a more environmentally friendly and Biodiverse approach.
The negative environmental impacts of monocropping on the long run outweigh most of the positive impacts. The best approach is to move away from a complete monoculture. Instead, adopt a well-planned diverse-culture system. In this system, the farmer continuously cycles the field through different crop types. These crops have unique environmental and economic relevance.
This cropping system allows for each crop species to complement each other as nutrient use efficiency is guaranteed. Crop protection is greatly enhanced. At the Ecofarms and Agroservices Experience Center, our local field advisers work with farmers. They guide and advise on field decision-making. This enhances a diverse cropping system, respecting soil health and market-driven crops. Farmers who have implemented such cropping systems are now enjoying the benefits. We hope this message will spread. It will generate more awareness. More farmers can embrace these systems. They can also share in the benefits.
