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

IGC Proceedings (1997-2023)

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 …

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

IGC Proceedings (1997-2023)

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

IGC Proceedings (1997-2023)

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

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.

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

IGC Proceedings (1997-2023)

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 …

Change In Migration And Pasture Utilization By Brokpa Pastoral Nomads: A Sustainable Adaptation Strategy For Climate Sensitive Arunachal Pradesh!?, Sanjit Maiti, S. K. Jha, Sanchita Garai, Vijay Paul, G. Krishnan, A. K. Bera, D. Bhattacharya, S. M. Deb

IGC Proceedings (1997-2023)

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, …

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

IGC Proceedings (1997-2023)

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 …

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

IGC Proceedings (1997-2023)

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 …

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

IGC Proceedings (1997-2023)

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, especially …

Breeding Wheat For Resilience To Increasing Nighttime Temperatures, Kathleen Russell, David A. Van Sanford

Plant and Soil Sciences Faculty Publications

Increases in global mean temperature since 1960 are largely attributed to the rise in minimum nighttime temperatures thereby decreasing diurnal temperature variation. Increased night temperatures are known to affect crop development. A multi-year study investigating the effects of increased night temperatures on soft red winter wheat (Triticum aestivum L.) varieties was conducted during the 2015-2016 growing seasons at the University of Kentucky Spindletop Research Farm in Lexington, KY. Thirty-six cultivars and breeding lines were chosen based on their genotypes at photoperiod and vernalization loci. This material was planted in a randomized complete block experiment with two replications and two …

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

IGC Proceedings (1997-2023)

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 …

Global Pattern And Change Of Cropland Soil Organic Carbon During 1901-2010: Roles Of Climate, Atmospheric Chemistry, Land Use And Management, Wei Ren, Kamaljit Banger, Bo Tao, Jia Yang, Yawen Huang, Hanqin Tian

Plant and Soil Sciences Faculty Publications

Soil organic carbon (SOC) in croplands is a key property of soil quality for ensuring food security and agricultural sustainability, and also plays a central role in the global carbon (C) budget. When managed sustainably, soils may play a critical role in mitigating climate change by sequestering C and decreasing greenhouse gas emissions into the atmosphere. However, the magnitude and spatio-temporal patterns of global cropland SOC are far from well constrained due to high land surface heterogeneity, complicated mechanisms, and multiple influencing factors. Here, we use a process-based agroecosystem model (DLEM-Ag) in combination with diverse spatially-explicit gridded environmental data to …
