Lomitas is a rural settlement located within the municipality of Santander de Quilichao, part of the department of Cauca. There is a division of this rural settlement in two sectors of its territory known as Lomitas Arriba and Lomitas Abajo. The population of Lomitas is composed principally of afrodescends, which have occupied historically the region for 200 years [1]. This rural community has experienced the change of its social dynamic and its environmental conditions, affecting thus the quality of life of its people [1] [2]. The inhabitants of Lomitas faced the dispossession and abandonment of their traditional farms by the expansion of the sugarcane agroindustry and the armed conflict with the presence of illegal armed groups such as guerrillas and specially paramilitaries [3] [4]. Based on testimonies of community members, the sugarcane crops of the rural zones of Lomitas started to be established approximately in 1987, replacing extensive livestock. Breeding of animals such as cows, horses, chickens and pigs was the main source of livelihood for the families, along with the intensive cultivation of coffee, rice and citrus. In 2000, the paramilitaries of the Farallones Front - Calima Block of the United Self-Defense Forces of Colombia (Autodefensas Unidas de Colombia or AUC) arrived to this rural settlement establishing training camps. This caused a wave of violence, and led to the forced displacement of its inhabitants to other places in Colombia and foreign countries [3]. Therefore, parcels of land were abandoned and some of them were taken by sugarcane workers. The difficult situation of poverty for the people who remained in their lands made them sell their lands at cheaper prices to big landowners, who rented the lands or sold sugarcane production to the mills. This extended the monoculture of sugarcane in the region: currently 70% of the Lomitas territory is used for sugarcane cultivation [4]. The decrease of the population in these territories is evident. The community census obtained from Community Action Councils reports that there are currently 700 inhabitants in Lomitas Arriba and 650 inhabitants in Lomitas Abajo [5] [6]. In Lomitas, there are currently three sugarcane mills: Incauca, La Cabaña and Mayagüez [1]. Studies of the regional environmental authority (Regional Autonomous Corporation of Cauca (CRC)) reported that there are 2.128,34 hectares (ha) of sugarcane cultivation of which only 879,62 ha are monocultures belonging to these mills [7]. The other 1.248,72 ha belong to individual landowners. Although the economy of this rural settlement is based on cultivation of the sugarcane, the population has not received benefits from the sugarcane agroindustry, considering that only 56 men of the community are sugarcane workers [1]. Indeed, the majority of the people live with temporal contracts by day of laboring outside of their community, evidencing high rates of unemployment and also secondary consequences such as drug addiction and prostitution. According to the testimonies of the community, the practices of illegal gold mining have also affected the community of Lomitas. The municipality of Santander de Quilichao has been considered a gold - rich territory and the exploration and exploitation of gold have been carried out since the beginning of the twenty-first century, bringing serious degradation of the water bodies and lands, loss of biodiversity and detriment of the communities [3]. Hence, the expansion of the sugarcane agroindustry, together with the illegal gold mining, has brought strong environmental and health impacts to this rural settlement. The sugarcane crops have produced contamination, given the high toxicity and inadequate biodegradability of herbicides used for weed control including glyphosate, ametrine, fusillade and DCMU, acid reaction of soils and accumulation of salts and aluminum [1] [8]. The contamination of water bodies such as the Teta and Catalina rivers by the dumping of toxic wastes and the high amounts of water used from the process of the sugarcane productions and gold mining are observed [1]. Research on the perception of the communities has also shown the changes of the landscape, the loss of the diversity of the vegetation cover including native forest, fruit trees and agricultural crops and human health impacts by the burning of sugarcane. After 2005, when the paramilitaries left Lomitas, the displaced people came back to their lands, finding that their homes were destroyed, their crops and animals no longer existed and their properties were invaded by the sugarcane agroindustry [9]. The fear of the population for denouncing this social and environmental injustice is reflected in the lack of collective action through years.
