in this situation if large quantity of CO2 are release in environment then it effect to environment and also directly effect to OZONE LAYER, that could be very dangerous for human being..
@ Vivek, I partially agree with you as increased temperatures may accelerate the rate of releasing CO2 resulting in less than optimal conditions of net growth. When temperatures exceed the optimal level for biological processes, crops often respond negatively with a steep drop in net growth and yield. The higher cost and labor, and the specific techniques needed in organic agriculture practice cannot allow producing rapidly a great quantity of food for a growing population. That's why organic agriculture is seen as a luxury agriculture which cannot be practiced by a large number of farmers in the entire world. Moreover in the poor country cannot afford the lesser yield in the initial year as compared to the chemical products. The production costs are higher because farmers need more workers Marketing and distribution is not efficient because organic food is produced in smaller amounts. Limited access to safe, effective, pest control options. More reliance on tillage and dependency on animal agriculture and availability of material are the other disadvantage of organic agriculture.There is also inability to fully use precision fertilization and genetically modified crops under organic agriculture.
I believe organic agriculture can be effective in all the existing growing environments.
The question of high temperature semi arid and arid environments does not restrict the ability to access organic methods.
The high temperature semi arid and desert environment is often notorious for very low organic matter soils with high alklalinity.
Organic materials and use of organic methods can be very helpful for these limitations.
Internationally the concern on the use of pesticides and synthetic fertilizers has give impetus to a market for organically produced foods which have significant price premiums in many marketplaces.
The ability to farm organically is limited based on the knowledge and lack of certifcation infrastructures in many areas and the lack of good education and technical support.
Organic methods can be used to improve health of farmers, workers and consumers.

Theoretically it seems true that low temperature is good for organic carbon buildup & storage mostly happened in temperate countries but agriculture is the applied form of all ecological principals. When the application part is come in reality the designing of system has to be done considering the prevailing soil and climatic conditions because these factors can’t be changed and here local ecology play great role as compared to this general ecology. Here in high temperature areas where I am working two factors have to be considered in designing organic system 1. In these areas efficient organic matter recycling is more important than buildup and 2. There are crops like pearl millet, green gram, cluster bean etc. of this region that respond good to low carbon, provided the organic system should be at least 4-5 years old and having sufficient population of perennials( trees, shrubs, grasses) that not only help in buildup but also preserving soil carbon. Also several cultural practices developed in this region for better utilisation of available resources. In brief the designing of organic system need to consider the ecosystem of that region and because this is the base of organic farming. Principals of temperate zone farming cannot be applied in tropical region in toto and vice versa.
