Robusta’s Rise: A Glimmer of Hope in a Changing Climate

Nestlé and Côte d’Ivoire’s Centre National de Recherche Agronomique (CNRA) have announced the results of a multi-year trial on robusta coffee varieties, yielding impressive increases in yields. The data shows up to an 86% increase in yields when planting a mix of six robusta varieties. This is a welcome respite from the bleak outlook on global coffee production.

Climate change, disease pressure, and persistent farmer profitability challenges have pushed robusta breeding efforts to the forefront. A review in Frontiers in Plant Science led by World Coffee Research’s Robert Kawuki underscored the urgency of robusta genetics development. The review highlighted the need for faster tools and stronger collaboration to keep pace with climate change.

A New Era for Robusta

Nestlé’s trial, conducted across four coffee-growing regions in Côte d’Ivoire from 2018 onwards, evaluated 18 robusta varieties for yield, flavor, green coffee quality, drought tolerance, and performance under climate stress. The results show that the six top-performing varieties – two developed by Nestlé and four by CNRA – have been officially registered in Côte d’Ivoire. These varieties will be distributed to cooperatives through the Nescafé Plan.

The implications of this trial are far-reaching. Robusta is often seen as a workhorse, accounting for roughly 70-76 million 60-kilogram bags annually. However, its genetic makeup has been criticized for being stagnant, with current variety-development cycles taking over two decades to come to fruition. Nestlé’s breakthrough may signal a new era for robusta breeding, prioritizing collaboration and innovation.

Climate Change: The Unseen Variable

Climate change is altering growing conditions across the coffee belt, making it increasingly difficult for producers to maintain yields and quality. The data from Nestlé’s trial suggests that the six robusta varieties performed better in drought-prone regions, with improved cup quality and reduced bitterness. This could be a game-changer for farmers struggling to adapt to changing weather patterns.

However, concerns have been raised about Nestlé’s involvement in breeding efforts. As one of the largest coffee buyers on the market, its influence cannot be overstated. While the company has been privately engaged in numerous breeding efforts, some have questioned whether its priorities align with those of small-scale farmers.

A Broader Industry Push

Nestlé’s trial is part of a broader industry push to improve robusta genetics. The review in Frontiers in Plant Science highlights the need for faster tools and stronger collaboration to keep pace with climate change. This push has been gaining momentum, with initiatives like World Coffee Research’s Breeding Program aiming to develop new varieties that are more resilient to disease and climate stress.

The success of Nestlé’s trial raises questions about the future of sustainable coffee production. Can robusta breeding efforts help alleviate farmer profitability challenges? Will this breakthrough pave the way for a more equitable distribution of benefits among producers, processors, and traders?

As we move forward, it will be essential to monitor how this research is implemented in practice. Small-scale farmers must have access to these new varieties, not just large-scale producers. The implications of Nestlé’s involvement will also shape the direction of breeding efforts.

The trial’s success offers a glimmer of hope in an otherwise uncertain climate. However, it also underscores the complexities and challenges facing the industry. Robusta breeding efforts will play a critical role in shaping the trajectory of global coffee production. Will this breakthrough signal a new era for sustainable coffee, or will it merely serve as another example of corporate-driven innovation without equitable distribution of benefits? Only time will tell.
