IGC Proceedings (1997-2023)

Long term monitoring of grassland being the largest ecosystem on earth plays an important role in understanding its productivity and transformation (changes) over time. With the availability of remote sensing data, most ecological and environmental problems caused either by human activities such as extensive agriculture, pastoralism which might lead to desertification, land degradation, loss of biodiversity and climate change amongst others can be monitored. For this study, vegetation cover was selected as the main source of examination and subsets of area covered with grasslands were profiled for further monitoring of grassland increasing and decreasing trends in selected areas of Central …

Changes In Stable Fraction Of Soil Organic Carbon And Microbial Structure In Response Of Grazing Intensity, Wenjie Lu, Yingjun Zhang, Liu Nan

IGC Proceedings (1997-2023)

Carbon sequestration is one of the most important ecological function of the grassland. Soils contain more carbon than in vegetation in the form of soil organic matter (SOM). But grassland soils are vulnerable to disturbances caused by human activities. Grazing may result in various disturbances to both soil and vegetation under different grazing intensities (Bai et al., 2012). Grazing led to the shifts in amount and composition of soil organic matter. In previous studies, the chemical methods were used to separate soil into the different pools according to the stability of SOM (Carvalho Leite et al., 2004), but they cannot …

Methane Emissions By Lactating Ewes Grazing Italian Ryegrass, Jean V. Savian, Armindo B. Neto, Radael M. T. Schons, Leonardo Barreto Maass, Diego B. De David, Teresa C. M. Genro, Cimélio Bayer, Paulo C. De F. Carvalho

IGC Proceedings (1997-2023)

Agriculture contributes 13.5% of global emissions of greenhouse gases (GHG) (IPCC 2007), and about 50% of CH4 and 60% N₂O from anthropogenic sources, while livestock contributes an additional 18% of global GHG emissions (FAO, 2006). Among the various sources with a potential negative impact on the environment, methane emissions for which livestock are mainly responsible have been highlighted for the agricultural sector. Studies on means to mitigate these emissions, and understand how integrated crop and livestock production systems may contribute to the reduction of greenhouse gases, are essential for the creation of public policies for environmental preservation.

Long-Term Impacts Of Stocking Rate On Soil Carbon Sequestration In Arid Areas Of South Africa, Deribe G. Talore, Eyob Tesfamariam, Abubeker Hassen, Jean-François Soussana

IGC Proceedings (1997-2023)

Overstocking is one of the most important factors which results in changes of carbon stocks (Reeder and Schuman, 2002) and soil degradation, particularly in sandy soil, vulnerable to degradation through physical erosion. South African (RSA) topsoil is characterized by the low level of organic matter (Du Preez et al. 2011). Like most other African countries, little is known about the level of C sequestration under various grazing strategies in the vast dry grassland areas of RSA. It is well known that long-term studies with various stocking rate would be able to shed light on the level of C sequestration …

Effects Of Livestock Grazing Intensity On Reproductive Changes In Festuca Ovina L., Somaye Alidoost, Masoume Amirkhani, Mousa Akbarlou, Mansour Mesdaghi

IGC Proceedings (1997-2023)

Reproduction and re-generation strategies, whether by sexual or asexual means, are important attributes of grazed plants. The Gramineae family is the main element of rangelands, grasslands and grassland ecosystems by virtue of their seed production and distribution mechanisms, and their tolerance of environment stresses (cold, heat, drought). Festuca ovina is a highly palatable and productive plant that has been recommended for drilling and sowing in the steppe and semi-steppe rangelands of Iran. The aim of this study, which was located in the Ghorkhoud region in North-east Iran, was to investigate the effects of different grazing intensities on reproduction of this …

The Effect Of Exclosure Grazing On The Distribution Pattern Of Two Important Shrubs In The Central Steppe Of Iran, Anahita Rashtian

IGC Proceedings (1997-2023)

As part of a program to improve management of rangeands, research is being undertaken on the effects of grazing intensity on vegetation communities, including the response of different plant species to long-term exclosure from grazing. Species dispersion patterns can be used as valid indicators for condition assessment of rangeland ecosystems. Landsberg et al. (2002) and Riginos and Hoffman (2003) found that excessive grazing changed the structure and composition of plant communities, increasing the abundance of some species and reducing the presence of others. Heavy grazing leads to the excessive defoliation of herbaceous plants, reducing their biomass, basal cover and …

Italian Ryegrass Establishment By Self-Seeding In Integrated Crop-Livestock Systems: Effects Of Grazing Management, Armindo B. Neto, Jean V. Savian, Olivier J. F. Bonnet, Radael M. T. Schons, Paulo C. Vieira, Marcela Santana, José Augusto Q. Díaz, Paulo C. De F. Carvalho

IGC Proceedings (1997-2023)

Recent reports have indicated that integrated crop-livestock systems (ICLS) can enhance sustained crop and livestock production by efficiently using agricultural system resources (Liu et al. 2012). In the subtropical South American regions, soybean (Glycine max L. Merril) and maize (Zea Mays L.) crops are widely grown after Italian ryegrass (Lolium multiflorum Lam) pastures. In this system, the pasture may be established by self-seeding. Self-seedling reduces pasture production costs and extends the grazing period. The stoking method, and especially the grazing intensity, can greatly affect the quantity of seeds added to the soil by affecting the demography …

Identifying Grazing-Driven Plant Indicators Of Rangeland Degradation In Semi Arid Zones Of Uzbekistan, Toshpulot F. Rajabov, Bakhtiyor K. Mardonov, Mahmud A. Muminov

IGC Proceedings (1997-2023)

The development of practical indicators of vegetation degradation is an important element in predicting and assessing rangeland health due to disturbances such as livestock grazing. Once established, phytoindicators provide a simple and visual operative way to diagnose active and possibly undesirable vegetation changes. This paper aimed to identify rapid, yet realistic and easily communicated plant indicators of rangeland degradation caused by intense grazing. The grazing gradient approach is applied to study plant traits affected by increased levels of grazing pressure. Qualitative and quantitative changes in key species of the plant community alongside successive changes of vegetation attributes along an apparent …
