Effect Of Climate Change In 50-Years Period On Grassland Productivity In Central Poland, Piotr Goliñski, Marek Czerwinski, Barbara Golinska May 2020

Effect Of Climate Change In 50-Years Period On Grassland Productivity In Central Poland, Piotr Goliñski, Marek Czerwinski, Barbara Golinska

International Grassland Congress Proceedings

In Central Europe, the climate change is predicted to bring more rainfall in winter, less rainfall in summer, and an increased drought risk (Trnka et al., 2011). Smit et al., (2008) reported that significant drops in grassland productivity can usually be attributed to drier summers. Also in Poland, the most important abiotic factor limiting grassland productivity is water shortage and its distribution during vegetative season. Indicating the influence of climate on grass vegetation growth could be an important tool in grassland management on the national, regional and single grassland scales. The aim of the study was to evaluate the effect ...


Climate Change Adaptation In Vulnerable Crop And Livestock Production Systems In Mgeta, Tanzania, Leif Jarle Asheim, Zabron C. Nziku, Lars O. Eik, Dismas Mwaseba, George C. Kifaro May 2020

Climate Change Adaptation In Vulnerable Crop And Livestock Production Systems In Mgeta, Tanzania, Leif Jarle Asheim, Zabron C. Nziku, Lars O. Eik, Dismas Mwaseba, George C. Kifaro

International Grassland Congress Proceedings

Awareness regarding effects of climate change on the environment and livelihoods is becoming more apparent than at any time before (Elisha, 2006). Among the farming systems that have attracted the attention in Tanzania, are those in Mgeta in thehigh altitude water catchment area in the Uluguru Mountains. Land degradation have been widely reported in Mgeta (Ponte, 2001), and is currently threatening the source of water for domestic use and livelihoods of the local communities. Increased occurrence of droughts and dry spells during the growing seasons might reinforce the problem. A robust cropping system toreplace the erosion vulnerable vegetables seems needed ...


Frost Tolerance, Deacclimation And Reacclimation Traits In Perennial Ryegrass, Mats Höglind, Hans Martin Hanslin May 2020

Frost Tolerance, Deacclimation And Reacclimation Traits In Perennial Ryegrass, Mats Höglind, Hans Martin Hanslin

International Grassland Congress Proceedings

The ability of perennial grasses to harden and maintain frost tolerance throughout the winter is crucial for winter survival. This includes the ability to resist deacclimation during transient mild spells in winter, and the ability to reacclimate when cold temperatures return. The latter traits are especially critical in regions with cycles of freezing and thawing, and lack of a stable, insulating snowcover that can protect the plants from extreme air temperatures. Such conditions are typical for many coastal areas in Northern Eurasia and America, such as the southwestern coast of Norway. The climate is changing and one of the consequences ...


Importance Of Grassland Management For Carbon Sequestration And To Mitigate Climate Change: A Review, Poonam Yadav, Sheela Choudhary, Sunil Dutt Choudhary, Praveen Kaushik May 2020

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

International Grassland Congress Proceedings

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 ...

Simulating The Effect Of The Climate Change, Genotypes And Management On The Productivity Of Forage Cowpea In Semi-Arid Regions Of India, Suchit K. Rai, Sunil Kumar, D. Deb

International Grassland Congress Proceedings

Climate variability and change due to increase in green house gases concentration and the resultant increase in temperature has led to notable changes in different sectors including water and agriculture which would impact food security (Rai et al., 2014) in many regions of the developing world, which are largely dependent on rainfed and labor intensive agricultural production (Ziervogel and Calder, 2003). Eco-physiological models are widely used especially the potential impacts of climate change (Gitay et al., 2001; White et al., 2011). The cowpea (Vigna unguiculata (L.) Walp.) is an annual herbaceous legume cultivated for its edible seeds or for fodder ...

International Grassland Congress Proceedings

The north-eastern states of India specially Arunachal Pradesh, one of the bio-diversity hotspot, is expected to be greatly affected by climate change. Climate change will not only adversely impact the biodiversity of Arunachal Pradesh, but also affect the livelihood of local communities as they fully dependent on the natural resources. The Monpa is a primitive tribe inhabiting parts of West Kameng and Tawang district of Arunachal Pradesh. The pastoral nomad of the Monpa tribe is popularly known as Brokpa. Transhumance system of livestock mainly yak (Poephagus grunniens L.) rearing is their main source of livelihood. In recent past, challenges of ...


A Comparison Of Fuel Reduction Methods For Wildfire Risk Management And Climate Change Resiliency In Mixed Conifer Forests In The Sierra Nevada, Heather Navle May 2020

A Comparison Of Fuel Reduction Methods For Wildfire Risk Management And Climate Change Resiliency In Mixed Conifer Forests In The Sierra Nevada, Heather Navle

Master's Projects and Capstones

Wildfires in the mixed conifer forests of California’s Sierra Nevada have been a common and natural disturbance for thousands of years, historically occurring every 3 to 30 years. The flora and fauna of the mixed conifer forest have evolved to depend on low to moderate severity wildfires for reproduction, foraging, and habitat. However, the Sierra Nevada has experienced dramatic environmental changes over the past ~150 years as a result of three main factors: wildfire suppression, climate change, and habitat loss. Because of the threat wildfires pose to human lives, property and timber harvest, they have been suppressed to an ...


Cultivating The Next Generation Of Pasture Scientists In Australia, Sarita Jane Bennett Apr 2020

Cultivating The Next Generation Of Pasture Scientists In Australia, Sarita Jane Bennett

International Grassland Congress Proceedings

Current students coming through agricultural faculties in Australian universities have grown up in an era of low wool and meat prices, the introduction and acceptance of no-till farming as the norm and a general decrease in mixed farming landscapes in favour of continuous cropping. Since the collapse of the wool reserve price scheme in 1991, wool prices declined and income on wool producing farms followed suit. R & D during this period has also declined from 5-4% agricultural GDP in 1986 to only 3% in 2005 and has favoured research related to cropping rather than that related to pastures and livestock ...


Sea Level Rise Vulnerability Analysis Of Mangrove Ecosystems Using Gis, Kayla Caldwell Apr 2020

Sea Level Rise Vulnerability Analysis Of Mangrove Ecosystems Using Gis, Kayla Caldwell

HCNSO Student Theses and Dissertations

Climate change is accelerating beyond what is natural due to excessive emissions from human activities. The sea level has been rising for many years and is currently at a rate of 3.6 mm/yr. Mangroves are known to only keep pace with a sea level rate of less than 1.2 mm/yr. Mangroves are particularly vulnerable to rising sea levels if they are not able to keep pace through vertical sediment accretion or inland migration. To test the vulnerability of the south Florida mangrove ecosystems to sea level rise, this study analyzed changes in the mangrove forest coverage ...


Using Expert Knowledge To Develop Management Actions For Tasmanian Lowland Native Grasslands Under Climate Change, Kerry L. Bridle, Louise Gilfedder, Nicholas Macgregor Apr 2020

Using Expert Knowledge To Develop Management Actions For Tasmanian Lowland Native Grasslands Under Climate Change, Kerry L. Bridle, Louise Gilfedder, Nicholas Macgregor

International Grassland Congress Proceedings

Climate change projections for Tasmania suggest that the climate in 2070 will be warmer than present, with increasingly variable seasonal rainfall (Grose et al. 2010). Results from climate change modelling suggest that grassland communities may not exist over their current range in the future (Prober et al. 2012). Lowland temperate natural grasslands have been greatly reduced in areal extent since European settlement in the early 1800s. Two ‘Lowland temperate native grassland’ communities are listed as critically endangered under the Environment Protection and Biodiversity Conservation Act (1999): Themeda triandra grasslands and Poa labillardieri grasslands. Careful landscape planning for current and potential ...


Ecological Restoration Of Common Pastures Through A Community Led Multi-Stakeholder Partnership, Giresh Mohan, Sarvashish Roy Apr 2020

Ecological Restoration Of Common Pastures Through A Community Led Multi-Stakeholder Partnership, Giresh Mohan, Sarvashish Roy

International Grassland Congress Proceedings

Kalyanpura watershed, spread over 5,175 ha area with 16 villages, is situated in the drought prone district of Bhilwara in Rajasthan. Prior to project initiation, only 27% of the area in Kalyanpura was under agriculture and the balance was mainly accounted for by village commons used for livestock grazing and fuel wood collection. Although the area receives an average annual rainfall of 700 mm, the undulating landscape, shallow soil cover and the absence of any soil moisture conservation resulted in high runoff and degraded commons. Recurring droughts and absence of irrigation facilities made farm based livelihood vulnerable to seasonality ...


The Ingredients Of Scientific Illiteracy, Marghuerite Crowell Mar 2020

The Ingredients Of Scientific Illiteracy, Marghuerite Crowell

Georgia College Student Research Events

As technology and medicine flourish in 21st century America through science, so does fear and opposition. This fear and opposition stems from the lack of an individuals understanding or education in the scientific field; simply called “Scientific Illiteracy”. Pressing issues involved with scientific illiteracy include vaccination, climate change, and evolution. Through extensive research in reading scientific papers, political pieces, statistics, and referencing other’s expertise, the culprits of this phenomenon prove to surpass just a lack of scientific education. Scientific Illiteracy forms from people’s religion, politics, core beliefs, and emotions. “Anti-vaxxers” lack of education of the chemical makeup of ...


Relationship Between Rainfall And Annual Forage Biomass To Build A Forage-Balance Guarantee System In Brazilian Semiarid, Ana Clara Rodrigues Cavalcante, Rodrigo Gregório Da Silva, Magno José Duarte Cândido, Jay Peter Angerer Mar 2020

Relationship Between Rainfall And Annual Forage Biomass To Build A Forage-Balance Guarantee System In Brazilian Semiarid, Ana Clara Rodrigues Cavalcante, Rodrigo Gregório Da Silva, Magno José Duarte Cândido, Jay Peter Angerer

International Grassland Congress Proceedings

Semiarid regions around the world are characterized by elevated annual evapotranspiration and irregular rainfalls (Creswell and Martin, 1998), resulting in a negative water balance in most part of the year. The high rainfall variability associated to a high pressure on natural resources generated a scenario of degradation, which is worrying for the future of many rangelands. In this sense, it is urgent to understand the processes involved in the sustainability of vulnerable ecosystems to keep them productive and profitable. Among the rural activities in the semiarid regions, the raising of livestock has been contributed to become the farms viable. To ...


How Climate Impacts The Composition Of Wolf-Killed Elk In Northern Yellowstone National Park, Christopher C. Wilmers, Matthew C. Metz, Daniel R. Stahler, Michel T. Kohl, Chris Geremia, Douglas W. Smith Mar 2020

How Climate Impacts The Composition Of Wolf-Killed Elk In Northern Yellowstone National Park, Christopher C. Wilmers, Matthew C. Metz, Daniel R. Stahler, Michel T. Kohl, Chris Geremia, Douglas W. Smith

Ecology Center Publications

  1. While the functional response of predators is commonly measured, recent work has revealed that the age and sex composition of prey killed is often a better predictor of prey population dynamics because the reproductive value of adult females is usually higher than that of males or juveniles.
  2. Climate is often an important mediating factor in determining the composition of predator kills, but we currently lack a mechanistic understanding of how the multiple facets of climate interact with prey abundance and demography to influence the composition of predator kills.
  3. Over 20 winters, we monitored 17 wolf packs in Yellowstone National Park ...


Rain, Rain, Gone Away. Decreased Growing Season Rainfall For The Dryland Cropping Region Of South-Western Australia, Tim Scanlon, Greg Doncon Feb 2020

Rain, Rain, Gone Away. Decreased Growing Season Rainfall For The Dryland Cropping Region Of South-Western Australia, Tim Scanlon, Greg Doncon

Journal articles

The shift in Indian Ocean sea surface temperatures in 1976 led to a change in rainfall for the broad-scale winter annual grain cropping and pasture region in the south-west of Western Australia (the WA wheatbelt). Agriculture in the eastern part the WA Wheatbelt was particularly sensitive to the change in rainfall because it is a marginal area for agronomic production, with low rainfall before changes in sea surface temperature. A second shift in sea surface temperature occurred in 2000, but there has been no analysis of the resulting impact on rainfall in the eastern WA wheatbelt. An analysis of rainfall ...


Planet At Risk From Grazing Animals?, Albrecht F. Glatzle Feb 2020

Planet At Risk From Grazing Animals?, Albrecht F. Glatzle

International Grassland Congress Proceedings

The famous FAO report “Livestock’s Long Shadow” (Steinfeld et. al. 2006) and hundreds of subsequent publications blamed domestic livestock, in general, and grassland-based production systems in the (sub) tropics, in particular, of causing serious environmental hazards such as climate change, claiming that 18% of anthropogenic greenhouse gas (GHG) emissions are from livestock, more than from the transport sector. Few reviews challenged this claim, and those that did received little attention from the media. Pitseky et al. (2009) revealed the double standard applied by the FAO in this matter. Whereas for livestock products a full life cycle assessment for GHG ...


Crop Production Simulation And Analysis Of Climate Scenarios Based On The Apsim Model For The Long Term Run Of The Western Loess Plateau, Xuan Yang, Yuying Shen Feb 2020

Crop Production Simulation And Analysis Of Climate Scenarios Based On The Apsim Model For The Long Term Run Of The Western Loess Plateau, Xuan Yang, Yuying Shen

International Grassland Congress Proceedings

The APSIM model is an effective tool for making decisions on agricultural management. The model can simulate the biophysical process in farming systems, particularly economic and ecological features of the systems under climatic risk (Keating et al. 1998). The APSIM model has previously been used in the Loess Plateau (Tan, 2007; Chen et al. 2008). Based on climate data from the Loess Plateau from 1961-2010, we simulated three commonly grown crops, wheat, maize and lucerne. Additionally, by applying three climate change scenarios, we attempted to determine the production risk in the future, and gain an understanding of the impact of ...


Identifying Target Traits For Forage Grass Breeding Under A Changing Climate In Norway Using The Basgra Model, Mats Höglind, Tomas Persson, Marcel Van Oijen Feb 2020

Identifying Target Traits For Forage Grass Breeding Under A Changing Climate In Norway Using The Basgra Model, Mats Höglind, Tomas Persson, Marcel Van Oijen

International Grassland Congress Proceedings

Grass-based dairy and livestock production constitutes the most important agricultural sector in Norway in economic terms, and 60% of the agricultural land in Norway is used for grass production. Climate change may have consider-able impact on the survival and productivity of grasslands, with consequences for the local supply of forage to live-stock, farmers’ income and the supply of dairy- and livestock-based food products to the global market. Farmers can adapt to climate change by choosing different grass species or cultivars or by changing management practices such as the timing and frequency of harvests. Plant breeders select new cultivars of grasses ...


Climagie: A French Inra Project To Adapt The Grasslands To Climate Change, Jean-Louis Durand, Jérome Enjalbert, Laurent Hazard, Isabelle Litrico, Catherine Picon-Cochard, Marie-Pascale Prudhomme, Florence Volaire Feb 2020

Climagie: A French Inra Project To Adapt The Grasslands To Climate Change, Jean-Louis Durand, Jérome Enjalbert, Laurent Hazard, Isabelle Litrico, Catherine Picon-Cochard, Marie-Pascale Prudhomme, Florence Volaire

International Grassland Congress Proceedings

Climate change in France, central and southern Europe is expected to provoke more frequent and more intense summer water deficits, with increased amplitude in temperatures, exposing the same perennial crops to frosts as well as to heat waves and severe droughts. The impacts on sown monospecific grasslands have been assessed using crop models (Durand et al. 2010) but with less accuracy in extreme situations. Since less work has been done on intra-specific genetic variability there is urgent need to investigate both ranges of climate conditions and genetic variability (Poirier et al. 2012). Phenology and plant productivity responses to water, temperature ...


Data Integration And Modelling For The Assessment Of Future Climate Change Impacts On Natural Pasturelands Of The Alps, Camilla Dibari, Giovanni Argenti, Marco Moriondo, Marco Bindi Feb 2020

Data Integration And Modelling For The Assessment Of Future Climate Change Impacts On Natural Pasturelands Of The Alps, Camilla Dibari, Giovanni Argenti, Marco Moriondo, Marco Bindi

International Grassland Congress Proceedings

Evidence shows that in the last century in the Alps area warming was roughly three times the global average and, according to future projections, this trend is expected to worsen in the next decades. Moreover, the species-rich permanent grasslands characterizing the marginal areas of the Alpine landscape are acknowledged as very sensitive and vulnerable ecosystems to climate change (IPCC 2007). So far several studies have investigated the climate effects only on specific Alpine grassland species at a very small scale, while a comprehensive assessment of the impact of climate change on Alpine mountain grasslands distribution and composition at a territorial ...


Climate Changes And Trends In Phenology Of Woody And Herb Plants In Inner Mongolia, 1981–2010, Yurong Wei, Yanfang Cao, Zhicun Wang, Xuebiao Pan Feb 2020

Climate Changes And Trends In Phenology Of Woody And Herb Plants In Inner Mongolia, 1981–2010, Yurong Wei, Yanfang Cao, Zhicun Wang, Xuebiao Pan

International Grassland Congress Proceedings

The phenology of plants is a comprehensive reflection of seasonal climatological and ecological conditions and may be used as an indicator of climate change (Thomas et al. 2000; Volker and Annette 2004; Li et al. 2005). Analysis was made of the dates of sprouting, flowering and defoliating of woody and herb plants observed on 24 Agricultural Meteorological Stations in Inner Mongolia, China from 1980 to 2010. To assess the potential future change data was analysed for the 2011 to 2050 period using the England Hadley Climate Centre scenario (Wei et al. 2012).


Precipitation Pattern Change Influence On Vegetation Of Xilingol Grassland In Inner Mongolia, China, Wulanbter, Yurong Wei, Pengtao Liu, Xirong Jiang Feb 2020

Precipitation Pattern Change Influence On Vegetation Of Xilingol Grassland In Inner Mongolia, China, Wulanbter, Yurong Wei, Pengtao Liu, Xirong Jiang

International Grassland Congress Proceedings

The Xilingol grassland covers the region bounded by 41’09”–45’31” N and 111’14”–118’25” E. It is representative of a typical steppe in northern China, with the major native grass species present being Aneurolepidium chinense and Stipa spp. However these grasslands have become increasingly degraded due to desertification and/or the impacts of human activities resulting in the previous climax plant community becoming substantially altered.

In the Xilingol League most weather station started observations around 1960 (earliest 1952), however, grassland phenology and biomass measurement only started in 1980. The growing season runs from the 1st May ...


Assessing Resilience Of Pasture Production To Climatic Changes, Brendan R. Cullen, Richard P. Rawnsley, Richard J. Eckard Feb 2020

Assessing Resilience Of Pasture Production To Climatic Changes, Brendan R. Cullen, Richard P. Rawnsley, Richard J. Eckard

International Grassland Congress Proceedings

Increasing temperatures and atmospheric carbon dioxide (CO2) concentrations, together with changes to rainfall patterns, will influence seasonal pasture production; however climate change projections for south eastern Australia are uncertain (CSIRO and BoM 2007). Despite this, climate change impact assessments generally rely on specific climate projections, but in this study an alternative approach was developed to test the resilience of production to incremental changes in climate.

Impacts Of Projected Climate Change On Pasture Growth And Safe Carrying Capacities For Three Extensive Grazing Land Regions In Northern Australia, Giselle L. Whish, Robyn A. Cowley, Lester I. Pahl, Joe C. Scanlan, Neil D. Macleod

International Grassland Congress Proceedings

The northern beef industry is a major component of the regional economies of Queensland, Northern Territory and northern Western Australia, and has contributed an estimated $5 billion to Australia’s economy in 2009-10. Projected climate change will have an adverse impact on Australia’s agricultural production (McKeon et al. 2008) with an expected 3.5% decline in beef production in northern Australia by 2030 (Heyhoe et al. 2008). The GRASP pasture production model (McKeon et al. 2000) has been used to evaluate impacts of climate change in Australia’s rangelands (Crimp et al. 2002, McKeon et al. 2008), with the ...


Impact On Grassland Biomass From Climate Warming And Drying, Suying Li, Li Yang Feb 2020

Impact On Grassland Biomass From Climate Warming And Drying, Suying Li, Li Yang

International Grassland Congress Proceedings

It is becoming increasingly urgent to assess the impact of climate change on grassland biomass due to the important role these grasslands play in animal production. The typical steppe in Xilinhot of Inner Mongolia is the most representative vegetation types in the temperate grasslands of the northern China. One means to determine climate change is using the Aridity index (AI, also referred to as the dry degree of climate in this article) that is based on both temperature and precipitation (Arora 2002; Bannayan et al.. 2010; Nastos et al. 2012). The objective of this paper was to indicate how the ...

The main objective of this study is to estimate pasture biomass changes in Mongolia using the simulation model CENTURY. For the study framework we used the fenced pasture biomass data from 1960’s to 2008, over 60 meteorological stations and simulation data of the carbon, nitrogen, aboveground and belowground biomass, potential evapotranspiration, evaporation, transpiration and precipitation data across these grasslands. The simulated climatic and other parameters were estimated meteorological station based and their differences between 2 time periods were calculated. With purpose to make comparison of the present situation to the future situation used Climate Change Scenarios under A2, A1B ...


Comparative Analysis Of Climate Change Adaptation Options Across The Southern Australian Livestock Industry, Afshin Ghahramani, Andrew D. Moore Feb 2020

Comparative Analysis Of Climate Change Adaptation Options Across The Southern Australian Livestock Industry, Afshin Ghahramani, Andrew D. Moore

International Grassland Congress Proceedings

Climate change is predicted to have a substantial negative effect on the productivity of grasslands across southern Australia (Moore and Ghahramani 2013). We used the GRAZPLAN biophysical simulation models to assess several possible grassland management and animal genetic improvement adaptations under SRES A2 climate change scenario. Simulations spanned the five dimensions of geography, time, global circulation models, enterprise, and adaptations. Impact of climate change was predicted to reduce profitability of livestock industry by 46%, 58%, and 72% at 2030, 2050 and 2070, respectively. Increasing soil fertility could return the average profitability of five livestock enterprises to its historical level at ...


Modelling Adaptation And Mitigation Strategies For Southern Livestock Industries Of Australia, Richard J. Eckard, Richard P. Rawnsley, Brendan R. Cullen, Matthew Bell, Karen Christie Feb 2020

Modelling Adaptation And Mitigation Strategies For Southern Livestock Industries Of Australia, Richard J. Eckard, Richard P. Rawnsley, Brendan R. Cullen, Matthew Bell, Karen Christie

International Grassland Congress Proceedings

Climate change will impact on the Australian grazing industries both through mitigation policies and the impact of warmer temperatures, increased atmospheric CO2 and changed rainfall patterns (Cullen et al. 2009; Eckard et al. 2010). Mechanistic models are useful tools to inform our understanding of the complex interactions between future climates and the soil, plant, animal and management in livestock production systems.

This paper summarises the results of a number of whole farm systems modelling studies investigating likely impacts of climate change, adaptation options and emissions implications for livestock production in southern Australia.

Paul, Alvaro Rincón, Rainer Schultze-Kraft, Steve Fonte, Timothy Searchinger

International Grassland Congress Proceedings

Forage-based livestock production plays a key role in national and regional economies, for food security and poverty alleviation. Livestock production is also considered as a major contributor to agricultural GHG emissions, however. While demand for livestock products is predicted to continue to increase, there is political and societal pressure both to reduce environmental impacts and to convert some of the pasture area to alternative uses such as crop production and environmental conservation. Thus it is essential to develop approaches for sustainable intensification of livestock systems to mitigate GHG emissions, addressing biophysical, socioeconomic and policy challenges. This paper highlights the potential ...
