Environmental Science: Sustainable Land Management Presentation

This presentation delves into the critical topic of sustainable land management, focusing on the multifaceted issue of land degradation. It begins by defining land degradation as a biophysical process driven by human activities, highlighting its undesirable and deleterious effects, with over 40% of agricultural land negatively impacted. The presentation explores various causes, including deforestation, unsustainable agricultural practices such as excessive fertilizer and pesticide use, and industrialization, which leads to deforestation and land damage. It then outlines several preventive measures like crop rotation, dam construction, contour farming, strip farming, and furrow and ridge formation. The presentation also suggests actionable steps, such as joining environmental clubs and undertaking initiatives to combat issues like salinization through proper tillage mechanisms. References to relevant research papers support the presented information, providing a comprehensive overview of sustainable land management strategies and their importance.

SUSTAINABLE LAND
MANAGEMENT

Summation of Land Degradation
• It is the process wherein value of biophysical
environment is affected through combining the
processes which are human induced acting on the land
(Blaikie & Brookfield, 2015)
• It is the disturbance caused to the land perceived to be
undesirable and deleterious and more than 40% of the
agricultural land is damaged in a negative manner

Causes of Land Degradation
• Deforestation- It is the aspect in which the cutting of forests
will adversely affect the soil (Sklenicka, 2016)
• Agricultural Practices- The different agricultural practices
such as excessive utilisation of fertilizers and pesticides have
adversely degraded natural quality and fertility of cultivation
land as in Europe there is 9.8% land is degraded and it affects
the sustainability (Willemen et al., 2018)
• Industrialization- It is the other factor wherein development
of industries for economic growth affects and leads to
excessive deforestation and land is affected

Prevention of Land Degradation
• Crop Rotation- The main agricultural practice wherein
various crops are grown on a rotation basis and it
assists in replenishment of soil (Mohamed et al., 2019)
• Dam Construction- It helps in reducing the velocity
which will be supporting the vegetation effectively
• Contour Farming- It is the farming across hill side and
it helps in diverting to avoid the erosion (Specht et al.,
2015)

Contd….
• Strip Farming- It is the practice wherein cultivated
crops are being sown which will be preventing
movement of water as it will be reducing 30% of
deforestation effectively
• Furrow and Ridge Formation- The formation of ridge
along with furrow during the irrigation time can helpful
in preventing the same (Qasim, Shrestha & Qasim
2017)

Implementation of Steps to be Taken by
Me
• Join Association and Environment Clubs- It is the first
step wherein it will be helpful in improving the issues of
deforestation and with reduction in deforestation, it will be
helpful for soil to regenerate can be restored
• Undertaking of Initiatives on side of Environment
Clubs- It is the other aspect wherein initiatives can be
undertaken as it will be working towards preventing
salinization through introduction of proper tillage mechanisms
