Food security and conservation agriculture of natural resources.

Abstract

Food security is one of the concerns that countries around the world attach to it a special importance for achieving increased agricultural production and economic growth while preserving and developing available natural resources. One of these natural resources is the soil in which all plant species are cultivated as a source of human food.This resource is very important to pay attention to, which in essence depends on a number of agricultural processes which should be applied to it to improve its properties, composition, biodiversity and protection from degradation, drift and erosion factors.
The current agricultural production systems in semi-dry areas apply many practices that, when applied in the long term, lead to soil degradation and loss of its chemical, physical and vital properties which has an impact on agricultural crop productivity. Hence the fundamental solution to avoiding these constraints and maintaining these resources is the conservation of natural resources because of their significant contribution to creating a natural balance of these resources and their implications for food security.
Conservations agriculture is one of the important agricultural techniques that has spread in recent years in many countries of the world, especially in South and North America and some European and African countries which have contributed significantly to sustainable agricultural development for achieving food security.

Conservation agriculture is a technique which depends on land cultivation with very limited tillage and the establishment of a permanent crop cover of previously cultivated crops and the application of a suitable crop rotation, These are linked with the application of integrated grass control and the use of appropriate tillage machines.
