Dietary choices are very often shaped or influenced by local production practices and cultural habits,&quot; Skea, who is one of the report&#x27;s authors, told reporters in Geneva.Land can be both a source and sink of carbon dioxide, the main greenhouse gas blamed for global warming, and better land management can help to tackle climate change, the IPCC said.But it is not the only solution and cutting emissions from all sectors is essential to quickly curtail global warming.&quot;The window for making these changes is closing fast. If there is further delay in reducing emissions, we will miss the opportunity to successfully manage the climate change transition in the land sector,&quot; it said.Since the pre-industrial era, land surface air temperature has risen by 1.53 degrees Celsius, twice as much as the global average temperature (0.87 Celsius), causing more heatwaves, droughts and heavy rain, as well as land degradation and desertification.Human use directly affects more than 70% of the global, ice-free land surface and agriculture accounts for 70% of freshwater use, the IPCC added in the report.Agriculture, forestry and other land use activities accounted for 23% of total net man-made greenhouse gas emissions during 2007-2016. When pre- and post-production activity in the food system are included, that rises to up to 37%.Last year the IPCC&#x27;s first special report warned that keeping the Earth&#x27;s temperature rise to 1.5 degrees Celsius (2.7 degrees Fahrenheit), rather than the 2C target agreed under the Paris accord, required rapid change across society.<div>FOOD SECURITY</div>The IPCC warned of more disruption to global food chains as extreme weather becomes more frequent due to climate change and said environmental costs should be factored into food.It projects a median increase of 7.6% in cereal prices by 2050, meaning higher food prices and an increased risk of hunger.While an estimated 821 million people are undernourished, changing consumption habits have already contributed to about 2 billion adults being overweight or obese.Per capita supply of vegetable oils and meat has more than doubled based on data since 1961 but 25 to 30% of total food produced is still lost or wasted.Yields of crops such as maize and wheat have declined in some regions, while those of maize, wheat and sugar beets have increased in others in recent decades.<div>FOREST FACTOR</div>While forests can soak up heat-trapping gases from the atmosphere, desertification and deforestation can amplify warming due to the loss of vegetation cover and soil erosion.Measures to cut emissions, such as the production of biofuels, biochar — made from biomass — as well as planting trees, will also increase demand for land conversion.Reducing deforestation and forest degradation could result in a reduction of 0.4-5.8 gigatonnes of CO2 equivalent, the report said.The Amazon, about 60% of which lies in Brazil, is sometimes called the &quot;lungs of the world&quot; due to the amount of CO2 it can absorb but it was not directly mentioned in the IPCC&#x27;s summary for policymakers.Brazil&#x27;s President Jair Bolsonaro has supported opening up protected areas of the world&#x27;s largest tropical rainforest to facilitate agriculture and mining since taking office in January.The report text is prepared by over 100 scientists but has to be approved by governments. In those discussions, Brazil and India were very active to protect their national agro-industrial interests, a source familiar with the talks said.<div>(Reporting by Nina Chestney in London and Stephanie Nebehay in Geneva; Additional reporting by Megan Rowling; Editing by Jane Merriman and Alexander Smith)</div>
