B4.- Optimization of greenhouse gases emissions in the rice fields of the Ebro Delta.



Name

B4.- Optimization of greenhouse gases emissions in the rice fields of the Ebro Delta



Background

Rice cultivation in flooded fields is considered to be a significant source of greenhouse gases (GHG) – especially of methane (CH4) and nitrous oxide (N2O). It is also known that one of the most efficient ways to reduce these emissions without affecting rice production is by airing the soil at specific times. Rice production is one of the most significant activities in the Ebro Delta, and represents 21% of the total rice production in Spain. Rice is cultivated in almost 22,000 hectares (68% of the Delta’s total surface area of 32,000 hectares). However, and despite the importance of this area for rice production, there have been no evaluations carried out regarding the GHG emissions produced by this activity. Neither are there any studies into how to optimize (i.e. reduce) these emissions by using different agricultural techniques.



Goals

To determine the levels of greenhouse gases (GHG) emissions from rice fields by different agricultural practices and different field characteristics.







Where

Different agricultural practices (different flooding levels, different fertilizers, etc.) will be carried out in 10 to 15 rice fields during harvest time and post-harvest time.



When

2015 and 2016



Expected Results

To find out which rice management practices minimize GHG emissions without affecting rice production or biodiversity. This will allow us to lay down the foundations for an emission management plan which is useful for the rice production sector.
