Question

write in detail about the following:-
- sustainable agriculture
-consequences or results of land degradation
-relation between conservation of energy and pollution​

Answer 1

Explanation:

Reviewing land use pattern it is observed that large forest areas have been converted to cropland creating unprecedented ecological imbalance with no scope of expansion of agricultural land without further damage to natural environment. In face of increasing demand for food grains intensive agriculture based on irrigation-fertilizer-high-yielding seed technology is the common practice. However, the intensive agriculture gives rise to serious environmental problems like pollution of water bodies with fertilizer and pesticides, contamination of ground water and land degradation apart from the loss of indigenous crop species and genetic diversity. Sustainable agriculture with its emphasis on preservation of ecology, optimization of economic and social benefits and conservation of energy is seen to provide stable and lasting solution. Ways and means have been discussed to operationalise the sustainable agriculture. Some of the aspects of sustainable agriculture have been illustrated through an example comparing farming practices of two farmers in two different regions of Bareilly district of the state of Uttar Pradesh in Northern India.
