Climate change and crop production challenges: An overview

Abstract

Correction: 25th August 2016 - p.260 paragraph 1 line 8 'Table 2' was changed to 'Table 8'Climate change has heterogeneous effect on crop production. Potential yield of some crops were found to be decreasing in different simulation models. High temperature, drought, salinity, excessive rain fall are the major stresses faced by crops in a changing climatic condition. Coastal areas of Bangladesh are highly vulnerable to climate change. It was found that a total of 1,405.57 MT yield are lost in different crops. Data shows the production trends of many crops remaining in a steady state or their increase is very slow compared to elapse of time. Some possible adaptation measures such as sorjan system, floating bed agriculture, growing crops in raised beds, harvesting rain water, cultivation of salt and flood tolerant crop varieties etc. were suggested to reduce possible climate change risk and to cope up with the current situation.Res.

Role of ICT on Agriculture and Its Future Scope in Bangladesh

“…[16]. Conversely, for development of climate change resilient technologies and prediction of future crop yield and weather data; different climate simulation models should also be taken into consideration [24].…”

Potential Hazards of Air Pollution on Environment, Health and Agriculture

“…HYV aus, aman, boro and wheat production was found to be highest at 660ppmv CO 2 +00 0 C. Wheat biomass and grain yield was maximum noted with 550ppm CO 2 concentration. Most of C 4 crops will be benefited by increased CO 2 intensity in terms of yield and biomass production as they bear kranz anatomy in the vascular tissues and have better efficacy to utilize the extra CO 2 during photosynthesis [43]. Yield loss of rice (about 15%), corn (about 20%) and wheat (about 40%) enhanced when amount of O 3 concentration was increased (Figure 5).…”
