Conflict and Mobilization
IntensityLOW (some local organising)
Reaction stageUnknown
Groups mobilizing:Local government/political parties
Local scientists/professionals
Forms of mobilization:There are very few information sources about the conflict such as research papers, academic essays of scientists. That is why not all forms of mobilization in the conflict are known to the authors.
There is start of salvation of territory. Creation reports, sharing knowledge and findings between state and researchers. Meetings between municipality representatives and citizens.
Impacts of the project
Environmental ImpactsVisible: Soil contamination, Soil erosion, Oil spills, Other Environmental impacts
Potential: Food insecurity (crop damage), Loss of landscape/aesthetic degradation, Deforestation and loss of vegetation cover, Surface water pollution / Decreasing water (physico-chemical, biological) quality, Groundwater pollution or depletion, Large-scale disturbance of hydro and geological systems
Other Environmental impactsLiterally, it is spill of oil products. "Sconto Buve" ltd researchers made a conclusion in 2015 that in the lagoons are found several new toxic and extremely dangerous substances. It is claimed that during so long time there is formed an accumulation of toxic gas - sarin, that is dangerous due to its volatility, so air is in danger. Due to pollution of ground waters all the flora & fauna are in danger. Use of hazardous water could lead to distinction of several species of fauna. Hypothetically, as the lagoons cover aprx. 3 hectares of the Incukalns land, it is degradation and loss of landscape which looks awful and can't be improved. This land is not proper for any use now. Moreover, after all the successful work done, still the area has to be closed for the any access which literally means loss of 3 hectares.
Health ImpactsVisible: Other environmental related diseases, Other Health impacts
Potential: Malnutrition, Occupational disease and accidents, Infectious diseases, Deaths, Exposure to unknown or uncertain complex risks (radiation, etc…), Mental problems including stress, depression and suicide
Other Health impactsStill there are not enough data that prove the possibility of exposure to unknown or uncertain complex risks, mental problems. But it is proved that hazardous chemicals lead to poisoning of organism, causing death. Time is needed to uncover any other possible effects of sarin on people's genetics and health.
Socio-economical ImpactsPotential: Lack of work security, labour absenteeism, firings, unemployment, Loss of livelihood, Loss of traditional knowledge/practices/cultures, Land dispossession, Loss of landscape/sense of place, Other socio-economic impacts
Other socio-economic impactsIn case of soil pollution in the whole north-eastern part of Latvia (Vidzeme region) a lot of farmers would be forced to give up the agriculture, lack of work security and safe resources in pessimistic scenario could lead to bankrupt of several crops' enterprises and factories (such as beer factories) who use the water of that region. As the result, this may lead to unemployment, people will be forced to change their lifestyles = loss of traditional knowledge/practices/cultures
Project StatusUnknown
Conflict outcome / response:Under negotiation
Development of alternatives:Start of the salvation of the territory. To solve this environmental conflict, citizens involvement is needed because the plan is ready, local authorities are concerned about the issue, however, the proper actions are not taken as fast as they should be because there is no pressure from suffering side.
There are reached agreements between 3 sides - EU Commission and Funds, Latvian government and company-liquidator. Work groups concluded that fast and effective solution - immediate removal and isolation of the waste from the environment - is needed.
Do you consider this an environmental justice success? Was environmental justice served?:Not Sure
Briefly explain:On the one hand, European Commission is aware of the problem, Latvian scientists and researchers also are monitoring and exploring the impacts and possible scenarios of liquidation of the lagoons, there is the agreement made with company - liquidator. State Environmental Service also pretends to work (few interviews and articles in state newspaper and radio).
On the other hand, due to the Soviet history of Latvia there is lack of feeling responsible, unfortunately, involved people do their work slowly and silently. There is lack of information in social media, so it is almost impossible to follow and observe the development of situation. There exists an opinion and a lot of discussions that in this situation the USSR (the country that no more exists) is responsible for this environmental crime . People are used to shaking off the responsibility and holding discussions around the roots of the problem, forgetting about the real danger and necessity to save the environment.
There are some works started to save the place, but there is no progress at all. The process of real action - restructuring of the lagoons has not even started. All we can see in Incukalns is a fence around the territory.
