These emissions include carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) and are therefore a major driver of climate change. The environmental pressures on food systems are likely to intensify, as humanity is arguably already operating beyond planetary boundaries. The projection for changes between 2010 and 2050 shows that these pressures will result in an increase of between 80 and 92 percent in GHG emissions in the absence of technological change and other mitigation measures. Apart from being a significant source of GHG emissions, food systems are significantly impacted by climate change. Uneven climate change effects, in combination with differences in adaptation capacity, could exacerbate existing inequalities between High-Income (HI), Low-Income (LI) and Lower Middle-Income (LMI) countries.","PeriodicalId":315063,"journal":{"name":"Food systems at risk.

Drivers such as population growth, urbanisation and climate change put a lot of pressure on resources that have become core issues for the future of food systems. Cropland availability is limited in most parts of the world, adding pressure for cropping intensification. Fossil energy and phosphorus shortages are expected to occur within a few decades, with particular impact in Low-Income (LI) countries where farmers are more vulnerable to volatile prices. The availability of very unevenly distributed freshwater resources shows a similar picture, with an increasing number of regions reaching alarming levels of water scarcity. Some world fish stocks have been overexploited and are now depleted. But the situation is not without hope. While we need to intensify food systems to meet the challenge of a growing population, new ways to produce with less impact on the environment and more resilience to climate change need to be widely adopted.","PeriodicalId":315063,"journal":{"name":"Food systems at risk.

Within food systems, agricultural production is the stage which plays the largest role in deforestation and forest degradation, and it is therefore the focus of this chapter. There is a critical link between food systems and deforestation. Arable lands most often have a forested past. It might be ancestral, with deforestation having happened in the early occupation of land by humans or be very recent on current forest frontiers. Over the past two decades, commercial agriculture has overtaken subsistence agriculture as the main driver of deforestation in LI and LMI countries, especially in tropical areas.","PeriodicalId":315063,"journal":{"name":"Food systems at risk.

The succession of food crises between 2008 and 2012 has brought the agricultural price regime and its implications for food security back to the forefront. Even though the increase of average agricultural prices could profit some farmers, part of the price increase corresponds to increased costs and urban dwellers, as well as many food-insecure food producers, depend on the market for their supply. In addition, environmental policies concerning the protection of biodiversity, climate mitigation and pesticide reduction could make these issues even more acute.","PeriodicalId":315063,"journal":{"name":"Food systems at risk.
