Here are a few examples cited by Jose Peirats:
"In Montblanc the collective dug up the old useless vines and planted new vineyards. The land, improved by modern cultivation with tractors, yielded much bigger and better crops. . . . Many Aragon collectives built new roads and repaired old ones, installed modern flour mills, and processed agricultural and animal waste into useful industrial products. Many of these improvements were first initiated by the collectives. Some villages, like Calanda, built parks and baths. Almost all collectives established libraries, schools, and cultural centres." [cited The Anarchist Collectives, p. 116]
Gaston Leval points out that "the Peasant Federation of Levant . . . produced more than half of the total orange crop in Spain: almost four million kilos (1 kilo equals about 2 and one-fourth pounds). It then transported and sold through its own commercial organisation (no middlemen) more than 70% of the crop. (The Federations's commercial organisation included its own warehouses, trucks, and boats. Early in 1938 the export section established its own agencies in France: Marseilles, Perpignan, bordeaux, Cherbourg, and Paris.) Out of a total of 47,000 hectares in all Spain devoted to rice production, the collective in the Province of Valencia cultivated 30,000 hectares." [cited in Ibid., p. 124]
To quote Peirats again:
"Preoccupation with cultural and pedagogical innovations was an event without precedent in rural Spain. The Amposta collectivists organised classes for semi-literates, kindergartens, and even a school of arts and professions. The Seros schools were free to all neighbours, collectivists or not. Grau installed a school named after its most illustrious citizen, Joaquin Costa. The Calanda collective (pop. only 4,500) schooled 1,233 children. The best students were sent to the Lyceum in Caspe, with all expenses paid by the collective. The Alcoriza (pop. 4,000) school was attended by 600 children. Many of the schools were installed in abandoned convents. In Granadella (pop. 2,000), classes were conducted in the abandoned barracks of the Civil Guards. Graus organised a print library and a school of arts and professions, attended by 60 pupils. The same building housed a school of fine arts and high grade museum. In some villages a cinema was installed for the first time. The Penalba cinema was installed in a church. Viladecana built an experimental agricultural laboratory.
"The collectives voluntarily contributed enormous stocks of provisions and other supplies to the fighting troops. Utiel sent 1,490 litres of oil and 300 bushels of potatoes to the Madrid front (in addition to huge stocks of beans, rice, buckwheat, etc.). Porales de Tujana sent great quantities of bread, oil, flour, and potatoes to the front, and eggs, meat, and milk to the military hospital.
"The efforts of the collectives take on added significance when we take into account that their youngest and most vigorous workers were fighting in the trenches. 200 members of the little collective of Vilaboi were at the front; from Viledecans, 60; Amposta, 300; and Calande, 500." [Ibid., pp. 116-120]
Peirats sums up the accomplishments of the agricultural collectives as follows:
"In distribution the collectives' co-operatives eliminated middlemen, small merchants, wholesalers, and profiteers, thus greatly reducing consumer prices. The collectives eliminated most of the parasitic elements from rural life, and would have wiped them out altogether if they were not protected by corrupt officials and by the political parties. Non-collectivised areas benefited indirectly from the lower prices as well as from free services often rendered by the collectives (laundries, cinemas, schools, barber and beauty parlours, etc.)." [Ibid., p114]
Leval emphasises the following achievements (among others):
"In the agrarian collectives solidarity was practised to the greatest degree. Not only was every person assured of the necessities, but the district federations increasingly adopted the principle of mutual aid on an inter-collective scale. For this purpose they created common reserves to help out villages less favoured by nature. In Castile special institutions for this purpose were created. In industry this practice seems to have begun in Hospitalet, on the Catalan railways, and was applied later in Alcoy. Had the political compromise not impeded open socialisation, the practices of mutual aid would have been much more generalised. . . A conquest of enormous importance was the right of women to livelihood, regardless of occupation or function. In about half of the agrarian collectives, the women received the same wages as men; in the rest the women received less, apparently on the principle that they rarely live alone. . . In all the agrarian collectives of Aragon, Catalonia, Levant, Castile, Andalusia, and Estremadura, the workers formed groups to divide the labour or the land; usually they were assigned to definite areas. Delegates elected by the work groups met with the collective's delegate for agriculture to plan out the work. This typical organisation arose quite spontaneously, by local initiative. . . In addition . . . the collective as a whole met in weekly, bi-weekly or monthly assembly . . . The assembly reviewed the activities of the councillors it named, and discussed special cases and unforeseen problems. All inhabitants — men and women, producers and non-producers — took part in the discussion and decisions . . . In land cultivation the most significant advances were: the rapidly increased use of machinery and irrigation; greater diversification; and forestation. In stock raising: the selection and multiplication of breeds; the adaptation of breeds to local conditions; and large-scale construction of collective stock barns." [Ibid., pp. 166-167]
Martha A. Ackelsberg sums up the experience well:
"The achievements of these collectives were extensive. In many areas they maintained, if not increased, agricultural production [not forgetting that many young men were at the front line], often introducing new patterns of cultivation and fertilisation. . . collectivists built chicken coups, barns, and other facilities for the care and feeding of the community's animals. Federations of collectives co-ordinated the construction of roads, schools, bridges, canals and dams. Some of these remain to this day as lasting contributions of the collectives to the infrastructure of rural Spain." [The Free Women of Spain, p. 79]
She also points to inter-collective solidarity, noting that the "collectivists also arranged for the transfer of surplus produce from wealthier collectives to those experiencing shortages." [Ibid.]
Therefore, as well as significant economic achievements, the collectives ensured social and political ones too. Solidarity was practised and previously marginalised people took direct and full management of the affairs of their communities, transforming them to meet their own needs and desires.
