Hydrological extremes and migration: How does water influence migratory movements?

Extremos hidrológicos y migración: ¿Cómo el agua influencia los movimientos migratorios?

 

 “Today environmental problems play a role in migration. Some migrations occur when there is either too much water, as in rising seas, tsunamis and floods, or not enough water. In these countries people depend on the environment for their livelihoods.”

Wennersten, John R. and Denise Robbins. Rising Tides: Climate Refugees in the 21st Century.

Since 1993, the international community has commemorated World Water Day on March 22 of each year to highlight the need to responsibly preserve and manage this resource. In 2020, the selected theme is “water and climate change”, which intends to make visible the changes in water availability associated with climate change and the need to implement adequate adaptation strategies to these new phenomena.

From a migration perspective, it is necessary to understand and address the relationship between water and human mobility. This relationship is particularly evident in situations of hydrological extremes; both when water is lacking and when excess water affects living conditions. In the Americas there are cases of both scenarios and it is worth remembering them when studying the relationship between water and migration.

  • Droughts and migration: When lack of water affects the livelihoods and subsistence of rural populations

Scientific evidence on climate change predicts more intense drought events in certain regions of the Americas in the future, such as in the small island states of the Caribbean, areas of Central and South America (IPCC, 2018). These phenomena are evident today in different countries. The Dry Corridor of Central America, which brings together areas of Guatemala, El Salvador, Honduras, and Nicaragua, and even Costa Rica and Panama, has had recurring drought events with significant effects on production and agricultural yields although with different problems according to geographical areas. In Chile, the state of mega-drought in the central zone since 2010 has required the declaration of agricultural emergency zones to alleviate the lack of water.

Recurrent drought events affect the livelihoods of local populations, particularly in rural and agricultural contexts, through decreased yields, reduced need for labor and even direct impacts on food security when income decreases, or production does not allow needs to be subsidized. These factors can provoke migratory movements when families seek better survival options in the face of drought, and there is scientific evidence that suggests households migrate locally or internally in response to drought (IPCC, 2019).

However, to attribute the cause of migration to drought phenomena is complicated for several reasons. On the one hand, drought can reduce the incomes of the poorest households, which no longer have the means to migrate, especially with regard to international migration (IPCC, 2019). Furthermore, droughts are often a gradual and progressive phenomenon, in which households often try various adaptation strategies before leaving their communities. The dependence on rainwater - due to the type of crop and the limitations of the irrigation systems - increases vulnerabilities in the event of a drought. The dependence on agriculture fed by rainwater is more than 30% in countries such as Guatemala, Honduras and Nicaragua, where the yield of corn and beans change greatly due to climatic variability.

The narrative around the motivating factors of the 2018 migrant caravans reflects some of these debates. While the press identified drought and climate change as a factor in explaining these movements, climate factors never appeared among the first motivations in surveys of migrants. Although there is some overlap, the areas most affected by drought in Honduras, for example, do not correspond to the first areas of origin of migrants according to IOM surveys. However, the high percentage of migrants who worked in the primary sector before their departure and the actual incidence of drought in various areas did allow for a glimpse of the impact of drought on the loss of opportunities at the local level.

  • Floods, tsunamis, hurricanes: Hydrometeorological disasters as a source of displacement

In reports from the Internal Displacement Monitoring Center (IDMC), the category of climate-related disasters includes storms, cyclones, typhoons and hurricanes, floods, drought, fires and others. These disasters caused 16.1 million new displacements in 2018, a higher number than displacements caused by conflict and violence (10.8 million) and by geophysical phenomena (1.1 million).

As recent examples from Irma, Maria (2017) and Dorian (2019) show, Caribbean countries are particularly exposed to extreme hydrometeorological phenomena in which strong winds and rains destroy communities and cause mass displacement. However, the Caribbean countries are not the only ones in the region suffering from flood displacement. In recent months there have been heavy floods in Mexico, Brazil and Colombia due to excess rain and the limited capacity of watercourses to channel the torrent.

Displacement due to floods can be temporary or more permanent depending on the situation of the communities before, during and after the disaster. Certain families can return to their communities of origin after the event, when the waters return to their channel. This type of mobility has been evidenced, for example, in communities in Brazil and Argentina, in which recurrent floods promote the seasonal mobility of families outside the danger zone during certain months of the year.

 

Vulnerability to floods also causes more permanent migratory movements, both for individuals and communities. Hurricane Mitch, for example, caused the departure of Honduran populations in 1998. Some of these migrants accessed the Temporary Protection Status (TPS) in the United States, a status that remains in force for Honduras after a judicial decision that curbed the will of the administration of shut down the protection system.

Planned relocations of populations often respond to the desire to reduce risks related to hydrometeorological phenomena and also represent a form of human mobility. These processes have taken place in many countries in the region. In Nicaragua, for example, several communities around Lake Managua have been relocated to limit the damage caused by regular flooding and improve the living conditions of the populations. Sea level rise is also leading multiple countries in the region, such as Colombia, Panama or Guyana, to consider the potential need to move coastal communities to areas that will not be flooded in the relatively near future (IPCC, 2019).

7 recommendations to promote the inclusion of migrants in host communities through social and cultural activities.

Categoria: Pacto Mundial sobre Migración
Autor: Carlos Escobar

The promotion of social and cultural activities as a mechanism to encourage interaction between migrants and host communities with the aim of advancing in the construction of more just and peaceful societies, is currently a topic of special interest in studies, policies and programs on migrant inclusion and social cohesion.

Taking Intergroup Contact Theory (IGCT) as a reference, different researches argue that the interaction of people from different places and contexts, under the right circumstances, favors trust and the change of xenophobic or discriminatory perceptions. Thus, intergovernmental agreements such as the Global Compact for Safe, Orderly and Regular Migration have integrated this perspective into their theoretical and conceptual body. In particular, Goal 16 "Empower migrants and societies to achieve full inclusion and social cohesion", calls for the creation of community centres or programs at the local level to facilitate the participation of migrants in the receiving society by engaging migrants, community members, diaspora organizations, migrant associations and local authorities in intercultural dialogue, exchange of experiences, mentoring programs and the creation of business linkages that enhance integration outcomes and foster mutual respect.

Based on the analysis and review of different research, the IOM, in its publication The Power of Contact: Designing, Facilitating and Evaluating Social Mixing Activities to Strengthen Migrant Integration and Social Cohesion Between Migrants and Local Communities – A Review of Lessons Learned, proposes a series of recommendations, based on empirical evidence, to encourage the participation of migrants and receiving communities in social and cultural activities.

1). Fun and goal-oriented

Designing and incorporating fun and exciting activities leads to a lighter and more welcoming environment for people to meet, interact and create social bonds. At the same time, setting common goals, which neither group can achieve without the participation of the other (cooperative interdependence), makes the activities more engaging and participatory.

2). Mutual appreciation

Participants should understand, recognize and appreciate culture, traditions and history as part of the process of bridging differences, maximizing each other's strengths and identifying commonalities. It is important that all individuals are able to identify how their contributions can have a positive impact on the achievement of common goals.

3). Shared ownership

Involving migrants and local communities in all phases of activities will increase their participation. This ownership empowers them, raises their self-esteem and opens up new opportunities for responsibility and commitment.

4). Guided Reflection

Dialogues and activities that allow for a certain degree of reflection help to create an atmosphere that is perceived as trusting, friendly and warm. Processing information and sharing personal and sensitive stories, which can evoke memories, are of utmost importance as long as they are carefully guided and accompanied by facilitators or project members.

5). Supervision and Trust Facilitation

Those responsible for group interactions, such as team leaders, facilitators, project staff or event planners, must play an active role in promoting equality within intergroup relations and creating an inclusive environment for all. This deliberate effort is crucial to overcome the natural tendency of participants to group themselves according to their most salient characteristics and status.

6). Sustained and regular intervention

It goes without saying that the more frequent, prolonged and intensive the participation, the better the attitude of each individual towards others. This means adopting an approach that rethinks the role of the people involved, who in turn will define the needs of their communities and ultimately take part in the design and organization of appropriate interventions.

7). Institutional support and partnership

The support of institutions such as local governments, media, government agencies and intermediary organizations is critical to promoting and facilitating constructive efforts to strengthen intergroup relations. The coordination of these institutions creates a system that can provide resources and incentives to promote and strengthen intergroup relations.

Social and cultural activities, understood as a programmatic intervention strategy to facilitate the inclusion of migrants in receiving communities, are important to the extent that they offer non-institutional spaces for interaction, where through spontaneous human contact, social ties are built based on experiences, stories, emotions and life trajectories of the participants. This facilitates the generation of trust between individuals, greater degrees of social cohesion and, of course, peaceful coexistence in communities, understood not only as the absence of conflict, but also as a positive, dynamic and participatory process in which dialogue is promoted and conflicts are resolved in a spirit of mutual understanding and cooperation, through the acceptance of differences, the ability to listen, recognize, respect and appreciate others.
