NEWS: Circular solutions are vital to curb enviro harm from cement and concrete

Demand for cement and concrete is set to grow, especially in developing countries to improve infrastructure and living standards. Experts say that solutions reigning in the sector’s environmental footprint are vital, especially curbing greenhouse gas emissions that could absorb a major chunk of our remaining carbon budget. A hardhatNEWS article highlights the detrimental environmental impact of cement and concrete production on climate change, human health, and biodiversity. Cement manufacturing, particularly, contributes significantly to global carbon emissions due to the high energy consumption and chemical processes involved. The growing demand for cement and concrete, especially in developing countries, further exacerbates these challenges. The article emphasizes the urgent need for circular solutions to address the environmental threats posed by the cement and concrete supply chain. Experts suggest a combination of technological advancements, material changes, improved resource ef

NEWS: The non–digital infrastructure Africa’s digital economy needs

All digital processes seek to produce a physical change in how people live by influencing inanimate objects and human behaviour. So, until a piece of technology produces an effect on something material (other than the atoms that make up technology itself) the chain is incomplete.

All digital processes seek to produce a physical change in how people live by influencing inanimate objects and human behaviour. So, until a piece of technology produces an effect on something material (other than the atoms that make up technology itself) the chain is incomplete. Right?

As a journalist covering the business of technology in Africa, I hear about (and use) digital innovation a lot, perhaps too much. Even though I understand the appeal and potential of digital technologies, I cannot help feeling occasionally like it is a copout for our failures at getting the basics of a modern economy right. It is not rocket that the non-digital aspects of living and working in Africa are more important than we often give them credit for. At one level, especially for those of us for whom Africa has been home since we were born, it’s easy to not even see these non–digital spaces (or the effect of the lack thereof). So we attempt to replace these gaps with street smarts (which are important, don’t get me wrong). But there is only so much street smart that can get your fresh fish through markets, or your beautiful software into corporate systems. Very quickly we find that innovation, even the digital version, needs feet to stand on. To get over the artificial limits imposed by having no feet, or two left feet (having too much of one good thing), we will need…

Roads, power, rail and agriculture input

Roads (especially), power, and things like fertiliser subsidies have been held over the heads of the voting populations of Africa by politicians. All three have also received huge financing commitments and fat allocations from government revenue, development partners, and other lenders. Despite this, the African Development Bank suggests that the continent’s infrastructure needs amount to $130–170 billion a year, with a financing gap in the range $68–$108 billion. Knowing African governments, I believe it is safe to say that these figures could have been several times lesser, but that in fact, they may end up several times more expensive than estimated.

There’s really nothing more to add to the well-established conversation that we cannot “startup” or digitise our way out of the rut other than to say that there is an unyielding limit beyond which the infrastructure needs of the continent cannot be leapfrogged.

Take the growth of African cities as one example. Lagos, Africa’s most populated city, consistently ranks in the low rungs of liveability indexes. In 2021, it was ranked last infrastructure-wise in a list produced by The Economist’s intelligence unit (EIU). But the city won’t stop growing in population. By 2035, the UN projects it will be home to close to 25 million people—the largest population centre in an emerging megapolis that could house as many as 51 million people on the West African coast.

How will Lagos keep up? How will any other city in Africa (the continent may double its population by mid-century) keep up? Only a little over 70 years ago, Africa accounted for only 10% of the global population, now the continent is hurtling towards 25% (mid-century) or as much as 40% (by the 2100s) of people on earth. Smart cities built around technology alone are an inadequate solution for managing this growth.

There’s no order to this list (road, power, rail and agricultural input). And the list is frankly not exhaustive. But, as a general guide, it provides a sufficient overview of the very material aspects of our lives that need to be transformed in an equally material way if our digital economy experiment will not falter and return to stagnation.

But the seemingly apparent failure of investment in infrastructure translating into economic development has led experts like David Ndii, chairman of Kenya’s presidential economic advisory council and founder of Kenya’s first economic think-tank, the Institute of Economic Affairs, to call for the model to be revisited in favour of an agriculture-led model. “African policymakers should embrace a more pragmatic economic agenda that recognises and capitalises on Africa’s comparative edge: a greater abundance of land rather than low-cost labour,” the professor argued.

But Ndii’s argument would carry better weight if we could demonstrate that agricultural efficiency only ended at improved productivity and better yields. Improved productivity for smallholder farmers may not be economically sound if they can only sell locally because they are limited in market access. Similarly agricultural improvements at a national level will be limited in impact if excess yield has little to no access to markets because roads are poor and seaports are inefficient. There are no easy answers. In my book, agricultural input includes offtake capacity, quality management, logistics, processing and retail value. All of this requires different forms of infrastructure to be efficient and cost-effective.

In short, agricultural input is, in fact, infrastructure itself. Meeting the infrastructure needs of Africa is not a contest between investing in agriculture versus roads or ports. And a digital economy will be a severely stunted apparition if it existed only as mobile apps for paying for goods and services. Because that is perhaps the only thing that you don’t need to have roads, rail and agricultural input for.

It will still need power, though.

People, people, people

People are an inevitable part of this story. The reason is obviously because it is people who will use (or not use) digital technology in their daily lives. But a second and a bit more obscure reason why people are a strong part of this story is that it is people who will determine whether a digital economy, digital infrastructure, physical infrastructure, or anything else for that matter gets built!

And Africa is severely lacking in the talent we need for this to happen. We are also facing high rates of unemployment, even as a growing number of qualified people move out of the continent. Justin Norman has an interesting series that is worth listening to (linked here). The question of what to do about the jobs question is not an enjoyable cocktail. But, my friends, these ought to be part of the questions that habit our waking hours.
