AB Land consolidation could be defined as an action of a structural nature whose main objective is to improve the profitability of farms by reorganising the land parcels, reducing their number, improving their regularity and minimising their spatial dispersion. However, this process can generate important impacts on the configuration and composition of agricultural landscapes.This doctoral thesis is based on the hypothesis of whether a process of land consolidation that incorporates environmental, landscape and conservation principles, designed according to landscape ecology criteria, can improve the heterogeneity and connectivity of the landscape and contribute to mitigating greenhouse gas emissions in the cereal steppes, without detriment to the improvement of the structure of farms.The first chapter analysed the evolution of the heterogeneity of a recently concentrated cereal steppe area and compared it with an adjacent one. As a consequence of the actions carried out since the beginning of this process, an improvement in spatial heterogeneity has been observed in the concentrated area, thanks to a greater diversification of the crop mosaic and the conservation of the few existing patches of semi-natural elements. It has also been found that the environmental impact studies of these processes and their final implementation in the land consolidation and associated natural environment restoration projects need to be improved.The second chapter has shown that by applying environmental integration measures from the early stages of this process, land consolidation, together with the associated environmental restoration project, can be tools that contribute to maintaining, and even improving, the connectivity of the landscape in a cereal steppe area. To achieve this objective, the preservation of the few patches of existing semi-natural elements during the process of land consolidation, together with the extension of their surface area by means of the actions carried out in the environmental restoration project, have been fundamental.In the third chapter it has been shown that, under the conditions given in this research, land consolidation can be considered as a useful process in the greenhouse gas mitigation strategy, in line with the current commitments derived from the Paris Agreement. It is also considered that priority should be given to land consolidation involving several municipalities and those developed in irrigated areas.
