Agrobiodiversity in Dominican republic based on various wild and cultivated plants is affected by human interventions, mainly agricultural activities, which vary from extensive to intensive, and the gap between the two is growing. The objective of this work is to analyse various agricultural practices based on cropping systems used in Dominican Republic, and to assess the impact of intensification on agrobiodiversity. 







Evaluation of agrobiodiversity was by Altieri method, reflecting the following aspects: diversification of the living species in the farm, the similitude of the present vegetation to the endemic one, permanent species in the farms, cultivable and non cultivable vegetation. In addition I formulated questions for assessment of perceptions about the management of biodiversity coming from different stakeholders: farmers, researchers and professionals of the farming sector. 







I considered four sites for the variability of the intensity of the agricultural practices, from the extensive to the very intensive cropping systems. 







The highest values of the index of intensification practices and the most critical condition for biodiversity are found in Juma, characterised with rice production with flood irrigation. The observed values for intensification practices in Los Guayuyos, with greenhouse production and Pedro Corto, with intensive cropping system, are slightly lower while the biodiversity in these two places is higher compared to the biodiversity observed in Juma. In Las Pastillas, location with extensive cropping systems, the intensification practices index is the lowest one, while the biodiversity index is the highest one of all four localities. 







Highest agrobiodiversity levels connected to extensive cropping systems can be explained with farm diversification and multifunctionality. Intensive cropping systems result with lower agrobiodiversity, however addition of sustainable farming practices fosters positive change towards agrobiodiversity improvement. In rice producing area flood irrigation system might be the main cause of loss of biodiversity. 







The implication of this work for rural development is in the consideration for better planing of  agricultural activities in an intensive or extensive agroecosystem to ensure the sustainability of the agricultural system. Modern practices related of the intensified agriculture are not always destructive for biodiversity; however they do not always improve the socioeconomic conditions of farmers.
