In three different pilot areas in Greece olive cultivation practices are applied that contribute to:
Climate change mitigation
- by reducing greenhouse gases (GHG) emissions
- by increasing carbon dioxide capture
Adaptation to new climate conditions
- by increasing fertility and water retention in olive groves soil
- by strengthening the economic and environmental sustainability of production
The cultivation practices
The cultivation practices that take place in the framework of the oLIVE CLIMA project are:
Practices for capturing organic matter
so that organic matter can return to its groves by:
- Recycling the wood produced from tree pruning as mulch / nutrition material
- Utilization of olive oil mill by-products with land application, either directly or after composting
deriving from either the process of olive growing or olive oil production
Practices for practical increase of CO2 capture
from the atmosphere by plants through photosynthesis and “storage” in plant tissue and soil by:
- Modification of olive groves flora
- Modification of olive trees pruning
Conservation practices of organic matter
through zero tillage for limiting erosion and destruction of organic matter, and improving the soil water storage capacity.
These practices contribute to long-term “storage” of carbon dioxide in the soil in the form of an increasing percentage of organic matter, improving fertility (e.g. by better retention of water and fertilizers) and reducing greenhouse gases (GHG) emissions.
The new cultivation practices are applied to each pilot area in both irrigated and arid conditions.
The effectiveness of the proposed practices in mitigating climate change, their impact on the production of fruit and oil and their viability in technical and economic terms are assessed through a program of samplings and measurements. Moreover, during the next 5 years, special mathematical models will be used to assess the proposed practices and compare them to conventional management practices.
