Effect Of Silting Yield Index On Biomass And Carbon Sequestration Potential Along An Altitudinal Gradient Of Subtropical Chir Pine Forests And Grasslands In North Western Himalaya, India, Debasis Mahato, B. Gupta, Matber Singh

IGC Proceedings (1997-2023)

Biomass is an important characteristic of vegetation and is regarded as an important indicator of ecological and management processes in the vegetation. Measures of standing crop also reflect the amount of energy stored in the vegetation, which can indicate the potential productivity at the site. Forests are important for carbon sequestration besides playing very important role in the global carbon cycle. They store about 80% of all aboveground and 40% of all belowground terrestrial organic carbon. This study comprises to estimate the biomass and carbon stock of chirpine forests at different altitudinal gradients.

Importance Of Grassland Management For Carbon Sequestration And To Mitigate Climate Change: A Review, Poonam Yadav, Sheela Choudhary, Sunil Dutt Choudhary, Praveen Kaushik

IGC Proceedings (1997-2023)

Grasslands, including rangelands, shrub lands, pastureland, and cropland sown with pasture and fodder crops, covered approximately 3.5 billion ha in 2000, representing 26 percent of the world land area and 70 percent of the world agricultural area, and containing about 20 percent of the world’s soil carbon stocks (Ramankutty et al., 2008). All ecosystems- forested ecosystems, agro-ecosystems, grassland, ecosystems etc. take up atmospheric CO₂ and mineral nutrients and transform them into organic products In undisturbed ecosystems, the carbon balance tends to be positive: carbon uptake through photosynthesis exceeds losses from respiration, even in mature, old-growth forest ecosystems.

Conservation Prioritization Of Semi-Arid Savannas In India: A Multi-Scale Landscape Approach, Abi Tamim Vanak

IGC Proceedings (1997-2023)

The semi-arid savanna grasslands of peninsular India are unique habitats that support a vast proportion of Indiaís agropastoralist community. They are also home to critically endangered species such as the Great Indian bustard and other endangered and endemic species such as the Indian wolf (Canis lupus pallipes) and blackbuck antelope (Antilope cervicapra). Unfortunately, savanna grasslands have not received the attention of conservationists or policy makers, resulting in a lack of protection for both the endangered and endemic wildlife as well as the habitat. Given the high human-dependence on these biomes, traditional conservation measures such as large protected areas are not …

The Potential And Limitations Of Grasslands For Livestock Production In West Shoa Zone Of Oromia Region, Ethiopia, Abule Ebro, Azage Tegegne, Adisu Abera, Endale Yadessa, Zewdie Adane, Berhanu Gebremedhin

IGC Proceedings (1997-2023)

Ethiopia holds the largest livestock population in Africa estimated at about 54 million heads of cattle, 25.5 million sheep, 24.06 million goats, 0.92 million camels, 4.5 million donkeys, 1.7 million horses, 0.33 million mules, 54 million chicken and 4.9 million beehives (CSA, 2012). Despite the huge livestock population, the productivity of livestock in general is low and compared to its huge resource its contribution to the national economy is below expected. Among the major problems affecting livestock production and productivity in Ethiopia, feed shortage in terms of quantity and quality is the leading problem (Alan et al., 2012). The …

Application Of Pastoralists' Knowledge To Natural Resource Management In Spain, Elisa Oteros-Rozas, María Fernández-Giménez, Ricardo Ontillera-Sánchez, José A. González, Federico Fillat-Estaque

IGC Proceedings (1997-2023)

Extensive livestock rearing has been acknowledged as an important tool for sustainable management of social-ecological systems and biodiversity conservation. In the Mediterranean Basin this relationship has been highlighted in mountainous and rural areas, where the co-evolved assemblages and dynamics of plant communities and grazing practices and patterns are mutually reinforcing. Among extensive livestock rearing systems, mobile pastoralism is a typical adaptation in semi-arid areas and mountainous regions where pasture availability is especially variable in time and space. In Spain, mobile pastoralism dates back to Neolithic and has survived until our days in different ways. An outstanding example of mobility is …

Adaptation To Changing Institutional, Market And Bio-Physical Environments: The Case Of China’S Grasslands, Colin G. Brown, Scott A. Waldron, John W. Longworth

IGC Proceedings (1997-2023)

In the modern world, small pastoral herder households living on grasslands in countries such as China face major challenges in adapting to changes in their institutional, market and bio-physical environments. In China, these changes have been profound over the last 30 years. Herders, their communities and others dependent on the grasslands have responded to these developments but not always as might be expected. In this paper, the sources of the macro-forces in China that have created the pressure for change at the grass roots are outlined and the micro-adjustments made by herders and others in response to these pressures are …

Economics Of Camel Rearing On Grasslands In Gujarat, Khem Chand, B. L. Jangid, Subhash Kachhawa

IGC Proceedings (1997-2023)

Camel in India is primarily reared for carting/draft, agricultural operation, transportation in addition to the secondary utility of milk and hair production (Saini et al 2006). The One humped or Dromedary camel (Camelus dromedarius) is an important livestock species uniquely adapted to hot and arid environments (Schwartz, 1992). It is important livestock specie contributing significantly in rural economy and livelihood of desert dwellers in Kachchh region of Gujarat. It still plays a very distinctive role in various agricultural operations and rural transportation in dry land farming (Rajput and Tripathi, 2005). The Kachchh region of Gujarat has large camel …

Steppes And Grasslands In Morocco: Diversity, Functional Ecology And Socio-Economic Role, Mohammed Sghir Taleb, Jalal El Oualidi

IGC Proceedings (1997-2023)

With Morocco’s geographical situation (at the crossroads between Europe and Africa, the Mediterranean Sea and the Atlantic Ocean), its diverse climate and habitats supports a varied natural vegetation. The floristic richness of the country is related to the heterogeneity of biotypes. From the desert to the high mountains and the littoral to the continental borders, Morocco offers varied ecological conditions that support many different plant species. Steppes and grasslands are important parts of the main plant associations encountered in Morocco. They contain a wealth of flora, play important ecological roles and, from a socioeconomic perspective, are highly significant.

Dynamic Of Soil Mesofauna Of Fixed Sand Dunes On The Songnen Grasslands, Northeastern China, Xiuqin Yin, Zhenhai Wang, Dandan Zhang

IGC Proceedings (1997-2023)

Grasslands cover vast land areas in semi-arid and semi-humid regions. Sand dunes, most of which are fixed sand dunes, form a large portion of grasslands. Vegetation on fixed sand dunes is an important part of grassland ecosystem productivity, and topographic position is one of the important factors resulting in the differences among vegetation, soil, etc. (Sakai and Ohsawa, 1994; Nagamatsu and Miura, 1997).

An important component of soil fauna ecology is to analyze the distribution of soil fauna and its influencing factors. On the small scale, the ozone factors become the dominant factor affecting the soil fauna (Frouz et al., …

Photosynthetic And Growth Response Of Triodia Pungens To Elevated Co2 Concentration, Lisa Xian, Susanne Schmidt, Fernanda Dreccer, Paul Memmott

IGC Proceedings (1997-2023)

Triodia (“spinifex”) is a widely distributed endemic C4 grass genus in Australia. Triodia species form the hummock grasslands which is one of Australia’s dominant vegetation types covering approximately 30% of the continental land mass in the arid zone. Hummock grasslands are commonly used as rangelands and Triodia plays an important role in the ecosystem by providing habitat for arid fauna and maintaining arid lands vegetated.

Currently, Triodia survive extreme temperatures, water deficit and low nutrient availability. Predicted changes for Australia’s arid climate under elevated atmospheric CO₂ (eCO₂) include reduction in rainfall and higher daily average temperatures in …

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 …

Microhistological Analysis Of Cows' Diet During A Severe Drought In The Semi Arid Region Of North Patagonia (Argentina), E. Schmale, L. I. Lindström, M. G. Klich

IGC Proceedings (1997-2023)

The continuous use of the livestock fields of the Middle Valley of Río Negro, North Patagonia, Argentina, combined with adverse weather conditions that occur periodically, have contributed to the degradation of rangelands. The historical annual average rainfall regime in the Valle Medio of Río Negro is 303 mm but between 2002 and 2011, the average deficit was 33%. According to the Rural Society of Choele Choel, due to the decreased forage on offer, the existence of cattle in 2011 dropped to 85,000 animals, representing 50% of the normal amount for the area. During these critical times of drought, when grasslands …

A Bayesian Model Of Pasture Curing, Helen G. Daily, Ross Corkrey

IGC Proceedings (1997-2023)

Curing percentage (the percentage of dead material in the sward) is a necessary component of fire behaviour modelling and subsequent fire danger ratings in grasslands. Current methods of estimating curing have limitations. Curing is controlled by leaf turnover in grasses but individual leaf turnover rates of themselves do not give estimates of curing. Bayesian modelling provides the potential to incorporate leaf turnover rates representing the entire life cycle of each leaf into a standalone model of curing from which statistical summaries can be generated and used in field models. In this study, curing percentage was estimated over thermal time for …
