Linking Carbon Forest Plantations on Abandoned Land with Increased Production of Food     - A real world implication of systems analysis -   • The Food and Agriculture Organization predicts a 34% increase in the world’s population from  2010 to 2050 with a corresponding growth in consumption patterns, expected to result in a 60% increase in food demand. While yield increases are important to satisfy this demand, preserving high-quality land and regaining abandoned land by the combination of forestry and agriculture provide further possibilities for sustainable resource management. • IASA’s GAEZ framework can be applied to assess agricultural quality of abandoned agricultural lands. In collaboration with Ferrero and its pilot Payment for Ecosystem Services hazelnut plantation project we argue that production on such land can be economically viable and technologically sound, land degradation can be reversed, while preserving carbon pools, enhancing biodiversity and simultaneously producing food, feed, fuel and fiber. • As demonstrated by our case study, linking forest plantations with increased production of food on human-induced degraded landscapes can effectively contribute to combating climate change while triggering significant environmental and socio-economic co-benefits.

(Source: IIASA Landflow analysis)  • Abandoned lands are often low quality or degrading but suitable for forest plantations or the production of specific food and non-food low-input crops; • Research shows that marginal and abandoned land would be suitable for fiber and biofuel production         (IIASA-OFID Biofuel and Food security)  • Hazelnut plantations are suited for combined food-feed-fibre-fuel production, ensuring that human and livestock requirements can be met without using any land with high biodiversity, protected and forested ecosystems.  • The case study demonstrated NET positive environmental impacts on soil, water, biodiversity and climate, halting and reversing degradation and indicate significant potential of hazelnut plantations.  • The application of carbon financial mechanisms on combined forestry with agriculture plantations proved to be suitable for establishment on abandoned but potentially highly productive lands.   • Measurable impact of training on halting land degradation. • Sustainable food production can be achieved on carbon plantations, with significant co-benefits on livelihood improvement and rural development.  • As a conclusion, afforestation can provide substantial additional land for agricultural commodities production to meet the food and fiber requirements of future generations.  The Climate and Education Partnership GAEZ results: abandoned and secondary land can be used for non-food biomass production Forestry combined with agriculture on abandoned land can improve the resource base APPLIED SYSTEMS ANALYSIS IN BEST PRACTICE: forestry with agriculture projects • At the global level more than half of deforestation associated with agricultural products concerns the livestock sector dominated by pasture expansion for ruminant livestock production.  • Agroforestry and inter-cropping of trees and crops helps reduce the use of herbicides and fertilizers;   • Afforestation with fruit and nut plantations goes beyond inter-cropping and offers further co-benefits in sustainable land-use practices. • Nut trees are suitable for afforestation and in general have low to moderate agro-ecological requirements but high tolerance to cold or heat stress; • Hazelnuts are less sensitive to diseases and can be produced with moderate use of fertilizers on abandoned, low-fertility or degraded  lands;        The afforestation with hazelnut plantation projects represents a replicable model for the efficient use of abandoned by low-input       food-fiber plantations Dominant land cover in Europe and Caucasus      Suitability of cereals and hazelnut-type crops on marginal land, including abandoned land      Suitability of cereals and hazelnut-type crops on current cultivated land A range of crops are suitable for inter-cropping and agro-forestry Suitability for production of woody biomass on  • Forest plantations producing cash-crop create permanent land cover and replenish soil vegetative stocks.
