Importance of Research and Development in Improving Cassava Production

The importance of researching and developing cassava to make it more valuable are as follows:

1. Enhancing Yield and Quality

Researching on cassava helps develop high-yielding and disease-resistant cassava varieties, which increase the crop’s overall productivity and quality.

2. Improving Processing Technology

Research and development in the technology for processing cassava reduces labor-intensive operations, increases efficiency, and improves product quality.

3. Addressing Challenges

Cassava research and development addresses key challenges in the cassava value chain, such as pests and diseases, agronomic problems, and limited access to improved planting materials.

4. Capacity Building and Technology Transfer

Research initiatives, like the Cassava Community of Practice and Partnership (CoPP), strengthen national agricultural research systems (NARS) and facilitate the transfer of technologies and knowledge to local breeding programs.

5. Sustainable Agricultural Development

Also, research in cassava contributes to sustainable agricultural development by promoting the use of improved practices, such as mechanized processing and efficient extension delivery systems to make the cassava business attractive to entrepreneurs.

Historical Background of Cassava Research and Development

Asian cassava practice in Asia

Early Efforts in Breeding and Cultivation

Cassava has been cultivated for centuries, with origins traced back to South America.

However, systematic research and development efforts on cassava began relatively recently.

Intensive cassava breeding research started after the establishment of the Central Tuber Crop Research Institute (CTCRI) in India in 1963.

The CTCRI built a rich cassava germplasm collection and began conducting research to improve cassava production.

In 1969, the International Center for Tropical Agriculture (CIAT) started building a cassava germplasm collection and in 1972, established its Cassava Program by assembling a multidisciplinary team to conduct both basic and applied research.

Later in 1983, CIAT established a regional cassava breeding cooperation program for Asia based in Thailand.

Conventional breeding techniques, such as the production of full-sib or half-sib progenies and mass selection, have been the main methods for cassava varietal development worldwide.

These efforts have had a strong impact on addressing the constraints faced by cassava growers.

Advances in Biotechnology and Genetic Engineering

In the past few decades, there have been advanced molecular breeding and phenomics which have proven to improve the cassava plant.

Researchers have used these new technologies to develop cassava varieties with desirable traits, such as disease resistance, low toxicity, improved nutritional value, and the quality of starch yielded.

The improvement has been able to increase the basic knowledge of cassava breeding, farming, nutrition and processing.

Recent developments in cassava research

Cassava production in African countries

Cassava has been the focus of extensive research efforts to improve its disease resistance, processing techniques, and nutritional value.

Recent advancements in cassava processing techniques, nutrition and disease resistance have improved the crop’s sustainability and the livelihoods of smallholder farmers and players along the value chain of cassava.

1. Introduction of Disease-Resistant Cassava Varieties

Breeding cassava varieties that are resistant to diseases is important for making sure the crop’s long-term viability is secured.

Recent research has led to the development of several improved varieties that can withstand major pests and diseases such as cassava mosaic disease (CMD), cassava bacterial blight (CBB), and cassava anthracnose disease (CAD).

These varieties have been developed through a combination of conventional breeding and marker-assisted breeding (MAS) techniques.

For instance, the National Root Crops Research Institute (NRCRI) in Nigeria has released 46 improved cassava varieties, including six beta carotene (Pro-Vitamin A) varieties, which have enhanced the crop’s nutritional value and disease resistance.

2. Use of Technology to Improve Cassava Processing Techniques

Cassava processing technology has been a significant area of focus in recent research.

Advances in biotechnology and genetic engineering have enabled the development of more efficient and cost-effective processing methods.

For example, the use of simple low-cost marker technology has been employed to pyramid useful genes for delayed post-harvest deterioration.

Additionally, genetic engineering has been used to reduce the likeliness of toxicity and improve the protein content of cassava roots.

3. Efforts to Increase Cassava’s Nutritional Value

Cassava is criticized because of its low protein value and micronutrients.

Recent research is geared towards improving the crop’s status on nutrition through genetic engineering and breeding.

For instance, the development of high-carotene and protein-based varieties has been a significant area of focus. These varieties have the potential to significantly improve the nutritional status of millions of people who rely on cassava as a staple food.

Opportunities for Further Cassava Research and Development

As we have seen, cassava research has made notable progress in developing improved varieties through conventional breeding techniques.

Cassava’s genetic makeup and long breeding cycles have limited varietal development, but the advent of genetic engineering and biotechnology promises new pathways for improved yield and quality.

This is achieved by the use of marker-assisted selection with genetics to develop new varieties that will improve the breeding process.

Expansion of Cassava Production into New Regions

Certainly, expanding cassava farming into other regions apart from the tropics will increase the attention it gets and prompt more research on the crop.

More research is of course needed to identify cassava variants that can adapt to different climates and environmental distress.

This will of course require intelligent collaboration involving all the players in the cassava value chain for customized development to specific needs.

Collaboration between Researchers, Farmers, and Policymakers

There is an opportunity for cassava research and development when researchers, farmers, and policymakers collaborate and exchange information, allowing its players to have basic or local knowledge and experience of manioc farmers.

This will help to identify needed support, technology and best practices.

For instance, the Cassava Community of Practice and Partnership (CoPP) has shown the need for such efforts hinging on the transfer and sharing of knowledge and technology for innovation and infusing it into the research agenda.
