  By 2050, it is predicted that there will be 9 billion people on the planet,
which will call for more production, lower costs, and the preservation of
natural resources. It is anticipated that atypical occurrences and climate
change will pose severe risks to agricultural output. It follows that a 70% or
more significant rise in food output is anticipated. Smart farming, often known
as agriculture 4.0, is a tech-driven revolution in agriculture with the goal of
raising industry production and efficiency. Four primary trends are responsible
for it: food waste, climate change, population shifts, and resource scarcity.
The agriculture industry is changing as a result of the adoption of emerging
technologies. Using cutting-edge technology like IoT, AI, and other sensors,
smart farming transforms traditional production methods and international
agricultural policies. The objective is to establish a value chain that is
optimized to facilitate enhanced monitoring and decreased labor expenses. The
agricultural sector has seen tremendous transformation as a result of the
fourth industrial revolution, which has combined traditional farming methods
with cutting-edge technology to increase productivity, sustainability, and
efficiency. To effectively utilize the potential of technology gadgets in the
agriculture sector, collaboration between governments, private sector entities,
and other stakeholders is necessary. This paper covers Agriculture 4.0, looks
at its possible benefits and drawbacks of the implementation methodologies,
compatibility, reliability, and investigates the several digital tools that are
being utilized to change the agriculture industry and how to mitigate the
challenges.
