According to the Theory of the Total Economic Value of the Ecosystem, the techniques of economic-environmental valuation allow us to identify the main environmental functions that are directly or indirectly reflected in the market, which makes them one of the most widely used techniques for the economic valuation of the environment. This research was carried out with the aim of estimating the environmental costs and benefits generated in a dairy agro-ecosystem and with the application of economic-environmental valuation methods. To this end, the general functions of support or load, joint production, habitat and regulation at the end of 2018 were studied, applying the dialectical-materialistic method, as the guiding method of the research, in addition to empirical methods based on scientific observation and documentary analysis and the measurement method to describe and analyze the behavior of the functions studied. For the economic-environmental valuation analyses, items such as gross benefit, direct costs and avoided costs were calculated. It was found that the goods and services existing in the dairy ecosystem contribute to the total economic value a very favorable economic benefit, which is supported by a correct management of them, standing out in the contributions made by the functions of joint production, support or load and habitat. The integral analysis of the functions that make up the total economic value of any livestock ecosystem offers the possibility of deepening its efficient management and what this activity contributes in a sustainable manner in Cuba.

In order to identify the edaphic macrofauna in five grassland agroecosystems from Granma province, samplings were carried out twice a year, between July, 2014 and March, 2017. The edaphic macrofauna was collected according to the standard methodology proposed by the Tropical Soil Biology and Fertility (TSBF) and by the complementary methodology of pitfall traps. The identification was performed with taxonomical references and keys, and with the cooperation of competent entomologists and taxonomists. The identified edaphic macrofauna, with both methods, in five agroecosystems, was grouped in three phyla, seven classes, 16 orders, 71 families, 121 genera, 63 species and 177 morphospecies. Insecta class was the best represented according to number of orders (11), while Araneae was the most represented order, with 17 families. Formicidae family had the best richness of genera and species, identified with 33 taxonomical units. Out of the identified orders, 17 were collected from monoliths and 14 from traps. Meanwhile, at taxonomical level, 46 were identified in monoliths and 63 in traps. It is concluded that the high presence of ants (Hymenoptera: Formicidae) determined a low taxonomical diversity of the edaphic macrofauna in all the studied agroecosystems. In addition, it is recognized the need of use of the complementary method of pitfall traps to obtain a more complete inventory of the edaphic macrofauna. [ABSTRACT FROM AUTHOR]
