1.2 Problem statement
Land degradation indicates temporary or
permanent long-term decline in ecosystem function and productive
capacity. It may refer to the destruction or deterioration in health of
terrestrial ecosystem, thus effecting the associated biodiversity,
natural ecological processes and ecosystem resilience. It also considers
the reduction and loss of biological / economic productivity and
complexity of crop lands, pasture, woodland, forest, etc. Across the
world over 20% of cultivated areas, 30% of forests and 10% of grasslands
are suffering from degradation, affecting about 1.5 billion people this
degradation may be the result of numerous factors or combination
thereof including anthropogenic activities such as unsustainable land
management practices and climatic variations (Bai et al., 2008). Land
degradation occurs in the form of depletion or total loss vegetative
cover, and loss of its biophysical and economic productivity through
exposure of the soil surface to wind erosion and water erosion, and
through salinization and water logging, leading to deterioration of the
physical, chemical and biological properties of soil. The continued loss
of vegetation through salinization and human activities also depletes
the world’s biodiversity, and it reduces the ability of natural
environment for carbon sequestration, with the consequent long-term
effects of global warming and climate; overgrazing in the case of
rangelands in particularly serious in arid regions. Such conditions
surrounded with very complex arising problems hitting severely the human
well being allow us to state plainly that we are in need to efficient
programmes to be implemented in order to face the enormous challenges we
are no facing to achieve our goal towards a sustainable use of the
natural resources Land and Water for rice production
1.3 Purpose of the study
The
purpose of this study is to examine the effects of rice production
systems on perceived soil degradation in Ekiti state, Nigeria.
Specifically the study:
assess the impact of rice production on soil nutrient
determine the effect of rice farming style on soil nutrient
assess the relationship between rice production and soil degradation
