The aim of the book is to characterize the concepts of territorial development and endogenous development as complementary, since local development strategies would be represented by the responses of local actors to the challenges of competitiveness. Endogenous territorial development is fostered through non-agricultural activities carried out in rural areas. These are activities in the manufacturing industry, construction, trade in goods and social services. This is a phenomenon of multiple professions and diversified sources of income, resulting from the decrease in the weight of agricultural activities in the employability and income composition of people and families living in rural areas. On the other hand, endogenous territorial development can also be stimulated by strengthening farms, especially family farms, by diversifying their crops. As an option for generating direct and indirect financial gains, diversification reduces production costs, provides environmental advantages and reduces the economic impact of various crises in the rural sector.
