An obstacle (also called a barrier or a stumbling block) is an object, thing, action or situation that causes an obstruction. There are, therefore, different types of obstacles, which can be physical, economic, biopsychosocial, cultural, political, technological or even military.


Physical barriers

Universal access is provided in Curitiba's public transport system, Brazil.

As physical obstacles, we can enumerate all those physical barriers that block the action and prevent the progress or the achievement of a concrete goal. Examples:

Barriers in sports

A youth competitor show jumping over obstacles in Denmark.

In sports, a variety of physical barriers or obstacles were introduced in the competition rules to make them even more difficult and competitive:

  • in the athletics, there are barriers in obstacle running contests of 110 meters and 3000 meters, as well as in high jump and in pole vault;
  • in equestrian competitions, there are also jumps over obstacles;
  • in tennis and volleyball, a net stands as an obstacle that divides the court;
  • in the cycling, motorcycle and motor racing, circuit designs are interposed with difficult paths to obstruct and render more difficult the competition;
  • in team sports, like soccer, football, basketball and volleyball, attack players are hampered by defensive players, that make it difficult to move or throw the ball towards the goal;
  • in other sports, such as Parkour, the competitor aims to move from one point to another in the most fluid and fast as possible, jumping obstacles of urban architecture that get in the way.

Economic barriers

A common scene of emigration during drought in the Northeast of Brazil. Here, residents of the city of Caraúbas of Piauí are transported in a van-style "pau-de-arara".

Can be defined as those elements of material deprivation that people may have to achieve certain goals, such as:

  • the lack of money as an obstacle to the development of certain projects;
  • the lack of water as an obstacle to human capacity to produce certain crops on the field and to their own survival;
  • the lack of light as an obstacle to mobility at night;
  • the lack of electricity as an obstacle to the benefits provided by electronic devices and electrical machines;
  • the lack of schools and teachers as obstacles to education and the fullness of citizenship;
  • the lack of hospitals and physicians as obstacles to a system for the improvement of public health;
  • the lack of transportation infrastructure as an obstacle to trade, industrial and tourism activities, among others, and to economic development.

Biopsychosocial and cultural barriers

People are prevented to achieve certain goals by biological, psychological, social or cultural barriers, such as:

  • diseases, as obstacles to human life in its fullness;
  • physical disabilities as obstacles to the mobility of handicapped, which can be facilitated by accessibility resources;
  • shyness as an obstacle to social relations;
  • fear as an obstacle that prevents facing potential enemies or socio-political opponents, or facing possible economic barriers;
  • social exclusion or the arrest of individuals as obstacles to socio-cultural integration into a community;
  • the lack of psychomotor coordination as an obstacle to the development of qualified abilities;
  • the level of mastery of the spoken idiom, or the differences between the spoken languages, as barriers to national or international social relations;
  • the different religions as obstacles to the mutual moral understanding or interreligious dialogue, nationally or internationally;

Political barriers

Obstacles or difficulties which groups of citizens, their political representatives, political parties or countries interpose to each other in order to hinder the actions of certain of their opponents, such as:

Technological barriers

The improvement of living conditions of any human community is constantly challenged by the need of technologies still inaccessible or unavailable, which can be internally developed or acquired from other communities that have already developed them, and in both cases must overcome such barriers as:

  • in the technology transfer between different countries, the trade and diplomatic negotiating skills with the countries which are providers of the desired new technologies;
  • in the internal development approach, the educational level of the community or country, the accessible collection of specialized information, their technological and industrial base, their institutional level of scientific and technological research, development and innovation, and the level of practiced international collaboration.

Military barriers

Berlin Wall at the Brandenburg Gate, 10 November 1989

When different communities or countries, which border or not, can not develop good relations, for economic, cultural or political reasons, they may exceed the limits of diplomatic negotiations, creating military defensive or offensive obstacles to their opponents or enemies, such as:

  • blocking or destroying physical resources or logistic interconnections, such as bridges, highways, ports or airports, creating barriers to migration, trade, tourism, etc.;
  • the invasion of the opponent's territory, seeking to block, destroy or use physical, logistical or strategic resources, in order to hinder existing threats.
