The WRS 2021, organised by IRSG (International Rubber Study Group) together with the Ministry of Agriculture and Rural Development of the Government of Côte d’Ivoire and co-hosted by the Association des Professionales du Caoutchou Naturelle de Côte d’Ivoire (APROMAC) the Fonds Interprofessionnel pour la Recherche et le Conseil Agricoles (FIRCA), was a prime opportunity for leaders, experts, government representatives and NGOs to discuss the current status of the rubber industry and explore the way forward to achieve sustainable and inclusive growth. This year’s WRS featured the very timely theme, ‘Facing the Future: Inclusiveness, Sustainability and Growth for the Next Normal’.

The WRS 2021 was officially opened by HE M. Jerome Patrick Achi, Prime Minister, Government of Côte d’Ivoire, in recognition of the important role that Africa can play as an emerging producer of natural rubber. The event has highlighted that the rubber economy could be a formidable engine for the continent, creating jobs and transforming its economic and social prospects, and providing opportunities for the youth and women – real key drivers of sustainable growth, development and peace. 

The WRS 2021 witnessed 29 eminent speakers from all parts of the world, about 200 participants directly linked to the virtual platform and significant public participation in Côte d’Ivoire, where stakeholders in the rubber sector interacted in person during the event.  

Innovative ideas and approaches emerged during the summit to address the new challenges that can change the global pattern of production and consumption in the rubber sector, market and policy discussions on new approaches in business and life to turn the crisis into an opportunity from the lessons learnt. Discussions around the decarbonisation commitment of governments justifying sustainable and secure supply chains for raw materials were focussed on supply chain collaboration, ensuring that raw material efficiency, performance and traceability are dealt with holistically.

An important debate took place on the impact of climate change on natural rubber systems, which has potential economic, environmental and social risks, identifying a set of policy recommendations that could facilitate the work of all stakeholders in the rubber value chain.

The latest IPCC report , published in August 2021, has highlighted that human activity is changing the climate in an unprecedented and sometimes irreversible way. Actions on the adaptation of natural rubber systems to climate changes are urgently needed and further investigations into the potential contribution of rubber to climate change mitigation.

Work-based on scientific knowledge is the precondition to identifying correct pathways to preserve and support the growth and prosperity of the natural rubber economy worldwide. In this field, IRSG has had a leading role thanks to the support of important R&D organisations such as CIFOR/FTA, IRRDB and CIRAD.

In his closing remarks, Salvatore Pinizzotto, Secretary-General IRSG, has pointed out that the main common point that emerged during the World Rubber Summit is the need to formulate policies and put into place people-centred actions. “If we look at the natural rubber sector alone, it sustains 40 million people with their families around the globe with a supply chain generating more than USD 300 billion. Furthermore, about 90 percent of the total world natural rubber production is sourced by smallholders. 

“To build an inclusive and sustainable rubber community, we need to work at local, national and international level – there is not a ‘one-size-fits-all solution – putting in place innovative forms of cooperation across national borders and a variety of actors – governments, business, academia and civil society. Reduce poverty-establishing mechanisms that could provide  smallholders with an adequate income level, implement an effective technology transfer on the field and support education and training among farmers, especially young people and women. These are some of the policies needed to implement sustainability. Leveraging digital technology in farming and green finance options encouraging climate change adaptation are other key policies to assure emission reduction and social inclusion."

 In closing the World Rubber Summit 2021, the Honourable KobenanKouassiAdjourmani, Minister of Agriculture and Rural Development, Government of Côte d’Ivoire, has strongly stated that Africa is completely committed to implementing sustainability practices in the rubber sector, making sure that all the rubber value chain is equitable, profitable and transparent.  

"Sustainability and circular economy are two aspects that we need to keep high on the agenda of all stakeholders in the rubber economy. We need to make sure that both natural and synthetic rubber sectors comply with the adopted 2030 Agenda for Sustainable Development." (TT)

Pirelli has chosen the softest trio in its range for the Mexico City Grand Prix, with the C3 as Hard, the C4 as Medium and the C5 as Soft. This departs from last year, when a compound step using the C2 as Hard proved less appealing than the softer alternatives. The second round of the Americas triple-header takes place at the circuit named after brothers Pedro and Ricardo Rodríguez, unique on the calendar due to its altitude of over 2,000 metres.

A large portion of the circuit has been resurfaced, covering Turn 16 to Turn 1 and Turn 7 to Turn 16, leaving only the first sector largely unchanged. New asphalt normally brings higher grip and lower roughness, though its actual characteristics will need assessment during the opening stages. The track is often dirty early on, with grip improving lap after lap, and that evolution could be more pronounced this year.

The Autódromo Hermanos Rodríguez has traditionally been one of the least demanding circuits on tyres, with low-speed corners and limited lateral loads keeping wear under control. The thin air reduces aerodynamic load, increasing tyre slip and making graining a factor to watch, possibly more so with the smoother asphalt. The circuit's low severity could favour a one-stop race, though tyre management to extend stints will remain important, particularly for the rear axle.

Strategy may depend more on driver confidence in a compound than on genuine tyre life limitation, with some teams favouring softer compounds for grip and others the Hard for consistency. The Soft could play a central role, having shown strong characteristics on low-severity circuits. Braking performance also warrants monitoring, as the altitude reduces aerodynamic efficiency and the long main straight into Turn 1 could increase lock-up risk. Last year's grid was split between one-stop and two-stop strategies. This will be the sixth Grand Prix under the Mexico City Grand Prix name, with Max Verstappen the most successful driver at the venue with five victories, matching Red Bull. The Pirelli Podium Cap celebrates Día de los Muertos, which falls on race Sunday.
