Rainwater Harvesting And Its Impact On Farming Systems, J. S. Samra
Rainwater Harvesting And Its Impact On Farming Systems, J. S. Samra
IGC Proceedings (1997-2023)
Landless, small holders and other poors supplement their livelihood and adapt to climate change by grazing, stall feeding with crop residues and fodder cultivated under rainfed and irrigated conditions. Improving productivity by conserving rainfall, ground water recharging, harvesting and recycling of rainwater especially in degraded open access or shared land with community participation was quite successful over a wide range of precipitation and ecological situations. Various types of trenches, bunding, vegetative barriers, gully plugs, ponds, check dams, land slides and mine spoils stabilization etc. retained more soil moisture, seeds, vegetative propagules etc. in situ and prevented soil erosion. It regenerated …
Emission Of Green House Gases From Grasslands And Their Mitigation, Prem N. Sharma, Shyam Khadka
Emission Of Green House Gases From Grasslands And Their Mitigation, Prem N. Sharma, Shyam Khadka
IGC Proceedings (1997-2023)
The concentrations of green house gases (GHG) in the atmosphere began in pre-industrial times and it continues to increase. This could result into an alarming increase in temperature of up to 5.4 oC by year 2100 due to a net global annual GHG emission of H 4.5-6.5 Gt C equivalent. About 18% of the world’s GHG are contributed by livestock and related activities on grasslands that are spread over almost 35 million Km2.These grasslands give livelihood to over a billion people most of who are poor. Twenty to 70% of the land surface area is degrading often …
Climate Change Impact And Adaptation In Temperate Grassland And Livestock Industries, Afshin Ghahramani, Andrew D. Moore
Climate Change Impact And Adaptation In Temperate Grassland And Livestock Industries, Afshin Ghahramani, Andrew D. Moore
IGC Proceedings (1997-2023)
Climate is projected to have negative impact on temperate grassland and livestock productions across the globe. Moderately elevated atmospheric CO2 in the near future is expected to increase plant photosynthetic rates but this is likely to be limited by soil nitrogen deficits. However, in Australia at least it is unlikely that positive effect of elevated CO2 on plant production be able to offset the negative impacts of climate change. Currently there is a considerable gap between actual and achievable production and profit in Australian grazing systems and many management and genetic improvements for climate adaptation would operate by …
