OPTIMISATION OF LAND USE FOR IMPROVED SOIL BASED ECOSYSTEM SERVICES: AN EXAMPLE FROM LATVIA

Valujeva, K.; Pilecka, J.; Grinfelde, I.; Nipers, A.
Abstract:
The growing demand for bio-based products worldwide provides opportunity for Central and Eastern European countries to increase agricultural and wood production. Nevertheless, increase in bio-based production is restricted by emission reduction targets set by climate policies. Meanwhile, the changes in Common Agricultural Policy after 2020 offer each Member State to develop targeted and regional specific policies to meet socio-economic and environmental targets at national scale. Sustainable land management requires understanding of trade-offs among multiple demands expecting from agriculture, land use, land use change and forestry sectors. Shifting from customary crops to crops with higher economic return can give immediate contribution to achieve socio economic targets, but at the same international commitments require maintenance of existing carbon stocks and increase of carbon sequestration capacity which can be achieved by changing farming practices. South-eastern region of Latvia is chosen as a relevant case study to show trade-offs between simultaneous increase in both bio-based production and carbon stock. The aim of the study is to find optimal approach for land use and improvements of management practices in south eastern region of Latvia to simultaneously increase bio based production and carbon stock. We use spatial land use model under different optimisation scenarios. Results show that production can be increased by 35.1%, while carbon regulation function kept constant, but this rises another problem as it has a negative impact on the supply of biodiversity (-9.2%).
