Food losses and waste are the
result of ineffective functioning
of food systems.
“Food loss” is defined too as
food available for human
consumption, but not
consumed.
Introductión
About 1/3 of the food produced in the world The term “post-harvest losses” in the PHL

treatment of seeds, fruit, or tubers, as a

Post-harvest Losses of
Cereals in Developing
Countries
This part of the article shows us how great
losses are generated and how these losses
are capable of seriously altering and
affecting several societies and populations
around the world, these losses can be
caused mostly by storage, which means
poor post-harvest handling.
Storage Losses in
Developing Countries.
The maximum amount of losses occurs during the storage of crops
due to the lack of adequate infrastructure.
Losses in storage can be classified into direct losses caused by
physical loss of goods and indirect losses resulting from the loss
of quality and nutritional value.
Insect Infestation. Mycotoxins
Of all biotic factors, pests are Mycotoxin contamination is another

Interventions to
Reduce Losses
In this part of the article we are
shown how, through improvements in
postharvest, it was possible to
optimize the food and it was
possible to make food yields in
countries like Uganda improve by
98%, in this way we can say that

Achieving Food Security, Sustainable
Development and Resilience Through the
Use of Genetic Diversity and Indigenous
Knowledge: SDG2
Integrating environmental sustainability and resilience to climate
change has enabled SDG2 to achieve the following benefits:
Achieving food security, sustainable development, and
resilience through the use of genetic diversity and indigenous
knowledge.
Preservation of the genetic diversity of seeds, arable crops,
farmed and domesticated animals and their related wild
species, grazing, fishery, or forest resources.
CONCLUSION
The conclusions show us how an improvement in production and
an improvement in the use of food in different parts of the world
with the training and recommendations in husband harvest that
were made to consumers and producers of these countries That is
why the post-harvest is important better help them there to
productivity a product and the more to expand its useful life
