Insects have been in a feature in agriculture since the end of the 19th century. Using a combination of new and old control methods is the best way to deal with our food competitors.
A government for the 21st century needs to work out how we can grow our food, manufacture goods and dispose of waste without making such a huge mess.
Agroecological techniques that mimic nature – the antithesis of GMOs and high-cost fertilizers – have made farmers in developing countries more resilient to extreme weather.
Field trials in Senegal show native shrubs can access deep-soil water and make it available to adjacent crops – a technique that could alleviate drought conditions in marginal lands around the world.
Water isn’t straightforward. And by putting the Nationals in charge of policy for water assets like the Murray-Darling Basin, the government will trigger a complex round of bureaucratic musical chairs.
The seed industry in sub-Saharan Africa suffers from many challenges. India, which has one of the biggest seed markets in the world, offers some lessons on how these challenges could be overcome.
High demand for coffee has pushed growers toward sun or ‘reduced-shade’ plantations that require more water and pesticides while reducing biodiversity.
Over the past 60 years, China has experimented extensively with policies and programmes to encourage the growth of rural enterprises. Africa could do well by following in these footsteps.
The demand for agricultural products in Africa is expected to rise over the next 35 years due to factors such as population growth, urbanisation, economic growth and changing diets.
South Africa’s agricultural industry has struggled over the past 20 years due to the country’s rush to liberalise the sector while other countries continued to support their farmers.
The controversial Shenhua Watermark coal mine in New South Wales recently cleared another hurdle along the way to being granted full approval to proceed. But there are major environmental risks which should still call the project into question.
Africa needs to step up the protection of its tropical forests.
By embracing science and technology, Australia’s agricultural industry could be more efficient, productive and sustainable.
Data from all over the globe suggest that bees are in decline, and we may lose a lot more than honey if bees are unable to cope with the changing climate and increasing demand for agricultural land.
The same conditions – ultimately tied to nutrient runoff – that created the damaging toxic blooms and dead zones in US waterways of recent years are forecast to return this year.
There will be increasing demands placed on our soil and water in coming years, so we need greater research into how to preserve and maintain these precious resources.
Vaccines aren’t just for animals anymore. Research shows priming plants with pathogen-derived compounds strengthens their immune systems and enhances protection against future attack.
The challenges of feeding a hungry planet are many. Gene editing crops to be more productive, nutritious or hardy could help, but concerns about GMOs abound.
The nine science and research priorities will help focus and coordinate our efforts, and aid government departments in supporting the future of Australian science.
