A quality assessment of the arracachia flour grown in the village of Anaime (Cajamarca, Tolima) was made by the e'ective method of drying by conduction. Samples of the existing varieties in Anaime were taken, in order to determine which variety has the best quality of flour after drying by conduction from the physicochemical and bromatological analysis. Out of the three varieties found in order of importance, the best variety was “paliverde” followed by “common” and #nally “cartagenera”. With the drying process by conduction high degrees of quality can be achieved with a high quality standard and nutritional value.

Reforestation of native species is a priority of our ecosystems intervened or severely affected. W. tomentosa is a dominant plant in the regional climax and very common in the mountainous forests of the northern Andes. In Colombia it is mainly found in the eastern cordillera. It is considered one of the main pre-climaxed slopes and hence its pioneering behavior as a competitor, that’s why ecological studies are needed, to know their propagation, physiology, among others. *e establishment of W. tomentosa is conducive to the development of other species of moorland and hillside locations.

In the rural municipality of Paipa, Boyaca many families rely on cattle breeding to obtain from this activity, su'cient income and resources to meet their basic needs, however little is known about the true role of this species in the nourishment safety of rural families in the municipality of Paipa in Boyacá, for that reason, this study aimed to analyze the importance of general breeding cattle in the nourishment safety of thirty peasant families in the municipality of Paipa, Boyacá and get to know the social and cultural roles that are generated by this livestock activity. The obtained result was that the cattle are raised as a second choice in the pursuit of economic resources, after the birds. In cattle production an average of "ve animals per farm are raised, the widely used breeds are the Normando, Holstein and crosses between them; milk production dominates with an average yield of 150 liters/week per family; income and costs production depend on the number of cattle raised, the gained income is used to purchase food for home, but savings are not encouraged; the consumption of dairy products is very low and beef cattle is not consumed within the household; animals management is in charge of all family members (both genders). In general, cattle farming make interesting economic contributions to the countryside families, but these revenues are used to purchase food of high nutritional value, also affecting the nourishment safety of the studied families.
