In the two year since Barbadian prime minister Mia Amor Mottley and I urged G7 and G20 countries to construct a fairer, more efficient global financial system, significant progress has been made.
Wealthy countries have started to re-channel special drawing rights (SDRs, the International Monetary Fund's reserve asset) to countries in need, while multilateral development banks (MDBs) have begun to implement reforms.
Moreover, special attention has been paid to mitigating the effects of climate change.
The World Bank introduced 'pause clauses' in new loan agreements so that countries hit by natural disasters or similar catastrophes do not have to make debt service payments.
At last year's United Nations Climate Change Conference in Dubai (CoP28), international policymakers launched the first-ever Loss and Damage Fund to help developing countries address the effects of global warming.
MORE NEEDS TO BE DONE
As G7 leaders convene in Apulia, Italy, from today, 13 June, they must resolve to do more to build a resilient, equitable, and sustainable future.
The climate crisis is accelerating faster than expected. My country, Zambia, is grappling with devastating drought conditions, exacerbated by the return of El Niño - a weather phenomenon that can cause dramatic effects globally.
The agriculture sector, which forms the economy's backbone and provides livelihoods for millions of Zambians, has been hit particularly hard.
Crop yields have plummeted, water supplies have dwindled, and food prices have soared, leading to a steep increase in malnutrition.
Despite the growing importance of other international forums amid rising geopolitical tensions, the G7 still has the power - and the responsibility - to take the lead in combating climate change, global hunger, and extreme poverty.
But to play its proper role, member countries must take decisive action at the summit.
To have the biggest impact, the G7 should focus first on replenishing the resources of the International Development Association, the World Bank's fund for the lowest-income countries and a highly effective source of assistance.
FUNDING LIFELINE
The IDA's 21st funding cycle (IDA21) offers an opportunity to address some of today's most pressing challenges, as it will provide a lifeline for those bearing the brunt of the climate crisis and facing food insecurity.
Given that G7 countries account for roughly two-thirds of donor contributions to the IDA, they are in a unique position to ensure that IDA21 is fully funded or, ideally, to achieve the ambitious US$120 billion replenishment target set by 19 African heads of state.
But to do so, the G7 must reverse the trend of declining donor contributions, which have dropped steadily from their peak in 2012, and commit to an increase of at least 25% in real terms from the previous funding cycle.
In addition to ramping up funding for IDA21, the G7 should take advantage of a new
mechanism that could put their unused SDRs to work.
Nearly three years after the IMF's historic allocation of US$650 billion in SDRs, it approved their use for hybrid-capital instruments.
This innovative approach allows countries to channel their SDRs through regional MDBs, which could then leverage these funds by a factor of four, mobilising much-needed finance for developing countries' green transitions and agricultural reform.
The G7 must throw its weight behind the hybrid-capital scheme and provide support for the African Development Bank (AfDB), one of the initiative's first beneficiaries.
Paving the way for effective and transformative investments in African countries - including Zambia - also requires a successful replenishment of the AfDB's Africa Development Fund.
IMPORTANT FIRST STEPS
Lastly, at a time when developing countries are contending with mounting debt levels, expanding the use of 'pause clauses', which offer a cost-neutral mechanism to creditors while providing meaningful relief to countries in crisis, is crucial.
In December, the World Bank, under Ajay Banga's leadership, incorporatedthese clauses into existing loan agreements for 45 small islands and states, not just new loans.

The G7 must build on this momentum by pushing for pause clauses in the existing loan agreements of all low-income countries and by advocating a wider range of covered shocks.
Broader implementation of such clauses would ensure that countries can focus on recovery and reconstruction efforts in the aftermath of a disaster.
These are important first steps in reforming the global financial system, but the G7 should set its sights on long-term changes to support much higher levels of public investment in African and other developing countries.
As a formidable grouping with far-reaching influence, the G7 has a responsibility to act boldly in boosting shared prosperity.
By fully replenishing IDA21, recycling their SDRs, and advocating comprehensive pause clauses, G7 countries can help lay the groundwork for a greener, healthier, and more just world for us all.
