At least 13 people have died in Ghana after torrential rains triggered widespread flooding in the Greater Accra Region, with authorities warning of further downpours. The disaster, which submerged entire neighbourhoods and destroyed critical infrastructure, comes as Commonwealth leaders convene in London to discuss climate adaptation funding. Dr Helena Vance reports.
Accra, a city of 5 million perched on a low-lying coastal plain, has long been vulnerable to flooding. But climate models indicate that rising global temperatures are supercharging the region's seasonal rainfall. A warmer atmosphere holds more moisture, a basic physical reality. For Ghana, this means precipitation events that used to occur once in a century may now happen every decade. The 2023 floods are a tragic case in point.
Ghana's National Disaster Management Organisation (NADMO) confirmed 13 fatalities on Tuesday morning, with several people still missing. The dead include a family of four swept away when their wooden home collapsed in the Ayawaso district. Schools and hospitals have been forced to close. The economic cost, still being tallied, will almost certainly exceed 200 million Ghanaian cedis.
The timing is politically charged. This week, Ghana's President Nana Akufo-Addo joins other Commonwealth heads of state in London for the Commonwealth Heads of Government Meeting (CHOGM). The official agenda includes trade, digital innovation and post-pandemic recovery. But the informal conversations will inevitably fixate on a single theme: who pays for climate resilience in the Global South?
Ghana and other developing nations face an impossible arithmetic. According to the UN Environment Programme, climate adaptation costs in Africa could reach $50 billion per year by 2030. Yet current international funding, primarily from wealthy former colonial powers, covers less than 10 per cent of that. The UK, a host nation with significant climate credibility issues after its own flooding in 2022, is being asked to lead a new resilience fund.
But the numbers do not add up. The UK's overseas aid budget, once ring-fenced at 0.7 per cent of gross national income, has been cut to 0.5 per cent. Treasury officials privately concede that any new commitment will be modest, at best. The disconnect between rhetoric and reality is plain.
For Accra, the immediate task is survival. Flood prevention infrastructure, including drainage canals and sea walls, has been underfunded for decades. The recent deluge overwhelmed what little capacity existed. Hydrologist Dr Kofi Mensah of the University of Ghana described the situation as a 'vicious cycle'. 'Each flood event causes damage that sets the country back years,' he told me. 'We dig drainage channels. Rains come and wash them out. Then we have less money to rebuild. The planet is warming. The air holds 7 per cent more water for every degree Celsius. This is not politics. This is physics.'
Beyond Ghana, the pattern is global. Pakistan's floods in 2022 submerged a third of the country. Australia's bushfires in 2019-2020 burned an area the size of Poland. The Commonwealth, a group of 56 nations, many of them small island states that face existential risk from sea-level rise, is a natural venue for collective action. But collective action requires collective investment. And that, so far, has been lacking.
The UK government has pledged £11.6 billion for international climate finance over five years, with a focus on adaptation. But campaigners point out that this is new spending only in the narrowest accounting sense. Much of it is repurposed from existing aid budgets. The distinction matters when lives are at stake.
As CHOGM begins, Ghana's mud-strewn streets are a silent rebuke to diplomatic niceties. The floodwaters have receded in some areas, leaving behind a crust of filth and debris. But the political storm is just gathering. For the 13 dead, the question of resilience is no longer relevant. For the thousands left homeless, it is everything.
