The pressure of human activity, combined with continuing natural processes of wind and water, has accentuated coastal dune erosion which is the process of removing or damaging to, dune vegetation exposes sand dunes to high coastal winds and wave action which eventually cause dune blowouts and sand drifts.
We can tell this by carrying out specific research (secondary data) on different types of media and internet use. We can use GIS and Google earth to go back in time using the historic button and measure using the ruler button how the blowout of the sand dune has grown over time. Or simply you could use the GIS for visual reference and obvious change in the landscape.
For secondary data we can also look at the Liverpool hope geography department index and their research as they have done a lot of detailed and extensive research into the Ainsdale sand dunes and how population has affected nature’s natural habitat. Also you could look on the internet at www.naturalengland.org.uk which shows the NNR status which help evaluate the effectiveness of the conservation strategies.
Field work is primary data. There are many fieldwork techniques that we could carry out to investigate the pressure of human activities on the coast. One of which is a Transect of a sand dune. This is a quantitative method which requires systematic linear sampling at regular intervals along a transect starting at the embryo dunes then leading to the grey inland dunes. However, since this transect will be over a large area of land it will be very hard to keep in a straight land which maybe one limitation of this method, because as you become off course and no longer on the transect line then results may become unreliable.
Another Field work technique is recorded interviews/ questionnaires. This involves us asking a representative range of stakeholders, for example NNR, this is
