The main drivers of tropical forest biodiversity loss are land clearing for agriculture, pasture and timber plantation development, followed by logging activities that degrade forests. Deforestation and forest degradation also significantly contribute to climate change, given that they...

The relationships between forests and climate change are complex and multidimensional. Deforestation and forest degradation are now recognised to be a globally significant source of greenhouse gas emissions, and it is asserted that reduction of forest-based emissions may be among the least...

Marine ecosystems and fisheries face serious threats from over-fishing, run-off of land-based pollutants, introductions and invasions of exotic species, coastal development and habitat alteration, unintended by-catch, and climate change. Annual global fish catches fluctuate between 80 and 90...

Deforestation continues at a significant rate, especially in developing tropical countries. The process is a consequence of pressures to realise the commercial value of the timber and/or the land, the latter typically for either agriculture or settlement. Forests are integral to a variety of...

As much as seventy times more water is needed to grow food than for domestic use. Severely waterscarce countries such as Egypt do not have enough water to grow their own food and need to import food from elsewhere. Countries like the USA, Australia, China, India, Mexico and Turkey have made...

In a little over a decade, the global population is expected to reach 8 billion. The task of feeding this growing population will become harder with rising natural resource constraints, declining or stagnant crop productivity, more frequent extreme weather events, and climate change. These...

Increasing population and consumption are placing unprecedented demands on agriculture and natural resources across the planet. Today, approximately a billion people are chronically malnourished while our agricultural systems are concurrently degrading land, water, biodiversity and climate on a...

The Sir John Crawford Memorial Address has been presented since 1985, in honour of the distinguished Australian civil servant, educator and agriculturalist in whose name the Crawford Fund was established. Sir John Crawford was a remarkable Australian who contributed at the highest levels, and...
