The process of sustainable development forms the basis for a
wide variety of international and national level policy making. Sustainable
development permeates policy and action at the international, national and
local level. Agriculture can be defined as artificial management to
enhance the food value of cultivated land.
crop improvement by conventional breeding relies on the gene
pool available in a given crop, and introgression of a new trait can take a
long period of time
Crop genetic improvement methods
GM or genetic modification is the common term used to refer
to the insertion of genes into genomes using artificial techniques instead of
natural crossing and recombination. These have made important contributions to
increasing agricultural yields but, as with any crop protection method when
overused, pests can evolve resistance. There is, thus, a need for a wider range
of GM traits for crop protection to be brought into use. GM crops have been dominated by two
major traits: the Bt endotoxin for resistance against lepidopteran insect
pests, and glyphosate herbicide tolerance. These have made important
contributions to increasing agricultural yields
Factors
influencing crop protection in an agro-ecosystem. Current trends are making the
system more vulnerable to pests, weeds, and diseases, but GM could provide
novel resistance traits and increase crop genetic diversity.
Nutritious food provides; proteins, vitamins, minerals and essential fats to our bodies with energy for grow and function properly. In particular, science examines food and how nutrients support our bodies and impacts our health. It recognizes the procedures by which we consume, process, digest, and store the supplements in nutrients, and how these supplements influence our bodies.
