South African exports to the rest of the continent have more than doubled over the past 20 years. This has been driven by agricultural products, including maize.
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.

Africa needs to step up the protection of its tropical forests.
Research and technology can improve the yield and sustainability of crops like wheat.
By embracing science and technology, Australia's agricultural industry could be more efficient, productive and sustainable.
Not all bees are honeybees. This is a green ‘sweat’ bee.
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.
Algae overload: Lake Erie algal bloom 2011.
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.
Soil and water are crucial resources that need to be carefully studied and preserved.
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.
Can science help the developing world stave off a food crisis?
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.
National priorities can help focus our research efforts.

How to trim agriculture’s global warming footprint?
About 10% of human-generated greenhouse gas emissions come from farming. Researchers are working on ways to address this piece of the global warming puzzle.

Multiple approaches to alleviating poverty help cater for different contexts and groups of people.
There is no one perfect package for alleviating poverty, but there is agreement on what the elements should be. Combination and sequence of interventions varies, depending on context and beneficiaries.
