Sydney, 16.12.2022 (SciDev.Net): A quick, affordable, non-invasive detection tool could help accelerate progress in meeting the UN Sustainable Development Goals’ target to eliminate malaria, say researchers who developed it.

The WHO’s global technical strategy for malaria 2016–2030 aims to reduce malaria incidence and mortality rates by at least 75 per cent by 2025 and at least 90 per cent by 2030 against a 2015 baseline. But by 2021, malaria case incidence and deaths are both off track by 48 per cent. Based on the current trajectories, the world will be off track in reaching the malaria targets by 88 per cent, according to Abdisalan Noor, head of the Strategic Information for Response Unit, WHO Global Malaria Programme.

To help get back on track, researchers from Australia and Brazil have come up with a handheld, smartphone-operated, near-infrared spectrometer that shines infrared light for about five seconds on a person’s ears, arms, or fingers to detect changes in the blood caused by malaria.

Investing in global agri-R&D also ‘benefits donor countries’

Sydney, 09.12.2022 (SciDev.Net): Investment in international agricultural research and development (R&D) not only increases the capacity of lower-income countries to tackle food insecurity and manage natural resources but also brings significant returns to donor countries like Australia, says a study commissioned by the Crawford Fund.

The study makes a case for increasing the proportion of the development assistance budget allocated to international agricultural R&D. “Collaborative research is a two-way learning. Both the recipient and donor countries benefit from the exchange of knowledge, insights, science and technical ideas,” says Neil Byron, lead author of the study launched on 1 December in Canberra.

Currently, only 2.5 per cent of Australia’s aid budget goes to agriculture R&D. “All the evidence suggests that we are seriously underinvesting. We can easily double or triple the [agriculture R&D] aid because the benefits — social, economic and environmental payoffs — are so much greater than the costs,” says Byron, director of Alluvium Consulting Pty Ltd. which prepared the report for the Crawford Fund.

Food early warning systems can stave off famines

Sydney, 30.11.2022 (SciDev.Net): As reliable sources of quality food diminish and record numbers of people are driven to hunger due to conflicts, climate change and economic downturns, feeding the global population of eight billion poses a major challenge that demands better food early warning information systems.

Conflict is the biggest driver of hunger, with 60 per cent of the world’s hungry living in areas affected by war and violence. Food and Agriculture Organization of the United Nations (FAO) simulations indicate that the war in Ukraine could result in 19 million more people facing chronic undernourishment globally in 2023 —  if reduced food exports from the breadbaskets of the Russian Federation and Ukraine continue to impact world food availability.

Acute food insecurity is likely to get worse in many parts of the world during the October 2022 to January 2023 outlook period, requiring urgent targeted humanitarian action to save lives and livelihoods, according to the 2022 Hunger Hotspots report of FAO and World Food Programme (WFP).
