Currently, it is not clear yet whether the results on environmental correlates of PA found in America or Australia are applicable to European countries, so further research is needed before transferring findings across continents. Since research on environmental correlates of food-intake shows that associations may well differ between countries [ 17 ], it is plausible that this is also true for environmental correlates of PA. Moreover, physical environmental attributes in Europe are likely to differ from an American or Australian context.

For example, European urban streetscapes are characterized by a more compact structure, whereas most American cities are less dense due to sub-urbanization and existence of peripheral centers [ 18 ]. Because of these dissimilarities in density, average trip distances in Europe are shorter than in the US [ 1920 ], which in turn can influence human behavior like active versus passive transport mode choices.

Bassett and colleagues strengthen the assumption that also the behavior itself can be a continent-specific phenomenon, by showing that active transportation trips are much more common in Europe when compared to North America and Australia [ 21 ].

In addition to the above-mentioned geographical and behavioral differences, there has been a recent boost in European studies investigating physical environmental correlates of PA in adult populations, making it relevant to update the existing European literature on this topic. Additionally, European research in this field is growing and therefore, this systematic review aims to provide an overview of the available European evidence during the last decade.

As PA can be subdivided into several domains e. Methods Search strategy Systematic searches were conducted across six electronic databases: A two-stage search was conducted to identify eligible studies published between January and August In a first stage, the third author JVC screened databases until January In the second stage, an update of electronic database screening was conducted by the first author VVHwho also performed all subsequent screening steps.

Figure 1 provides an overview of the search protocol, according to the PRISMA statement [ 23 ] and specifies the used search terms. The earth is a source of useful and valuable minerals like gold, diamond and oil.

Magadi are important sources of minerals like salt and soda ash. People climb mountains and hills for enjoyment.

WASH: Context and Environment

Rivers, lakes and the ocean are used for water sports, swimming, and sailing. Rivers and dams are used to generate electricity.

Masts to improve communication are set up in highland areas to improve communication. Dry plateaus like the Nyika plateau are good for keeping livestock and nomadic pastoralism.

Mountains and highlands are sources of rivers since the ice melts to water. Some lakes and rivers provide water for irrigation. Some features in the Rift Valley are sources of minerals, for example, salt and soda ash at L. Magadi and fl uorspar at Kerio Valley. Forests found at the foot of high mountains and within the Rift Valley provide raw materials for some industries, for example, wood and timber used in paper making industries and saw mills.

Forests are home to wild animals which attract tourists. Prior to industrialisation, the impacts of human activity were not very significant because the technologies used were not capable of modifying the environment on a large scale. People at that time lived in agricultural societies using hand tools and simple technologies with limited environmental impact Figure 1. Industrialisation has allowed for a greater exploitation of resources.

For example, we now use powerful chainsaws to cut down trees and industrially produced chemical fertilisers and pesticides for crop production.

These changes have rapidly increased the human impact on the environment. The links between human activity and the environment are complex and varied, but can be grouped into two main types of activity: These are described in the following sections.
