The Influence Of Rising Atmospheric Co2 On Grassland Ecosystems, J. A. Morgan, P. C. D. Newton, J. Nösberger, C. E. Owensby
IGC Proceedings (1997-2023)
Increasing atmospheric CO2 concentrations and climatic change will have significant effects on the ecology of grasslands. This paper evaluates results from four CO2 enrichment studies in contrasting grasslands. A Swiss study investigates the effects of elevated CO2 (600 μL L-1 CO2) on perennial ryegrass (Lolium perenne L.) and white clover (Trifolium repens L), a New Zealand study examines how elevated CO2 (475 μL L-1 CO2) affects a botanically diverse pasture, and studies in the Kansas tallgrass prairie and the Colorado shortgrass steppe investigate the effects of an approximate …

Morocco’s drylands cover over 90% of the land area; low and irregular rainfall and high potential evaporation contribute to extremely high-water deficits. These phenomena have greatly impacted rangeland hydrology and nomadic and transhumant pastoralism. To adapt to this predominant water deficit, the inhabitants of these areas have developed two forms of lifestyles, which include household and livestock mobility: (i) a pendulum movement for seasonal transhumance between the mountains and their bordering plains; and (ii) random nomadic mobility regulated by the sporadic frequency of rains and thus water availability. In both cases, this mobility is controlled by the degree of development …

Producing Useful Knowledge For Sustainable Development, K. A. Galvin
IGC Proceedings (1997-2023)
Africa makes a relatively minor contribution to global greenhouse gas emissions compared with developed nations, yet the African continent will be increasingly vulnerable to climate change processes in the coming decades. Critical challenges include meeting basic needs for food, water, shelter, and other necessities without undermining biodiversity and ecosystem services. Coordination efforts to address multiple global change related stressors has generally occurred at the national level and taken an external approach, with national governments favoring collaboration with foreign-based NGOs and other international institutions. However, the involvement of actors at the local level correlates with decisions that are better adapted to …
Climate Change Policy Narratives And Pastoralist Predicaments In The Horn Of Africa: Insights From Ethiopia And Kenya, T. Campbell
Climate Change Policy Narratives And Pastoralist Predicaments In The Horn Of Africa: Insights From Ethiopia And Kenya, T. Campbell
IGC Proceedings (1997-2023)
Drawing on the findings of a two-country case study, this paper examines the discourses and narratives found in contemporary climate change and national development policy in Ethiopia and Kenya, the actors shaping those policy narratives, and in turn, their consequences for pastoralism. The research reveals that while concerns around climate change and calls for strengthening resilience of dryland communities have given a new impetus to pastoral development, old arguments and assumptions that depict pastoral areas, and pastoralists, as unproductive and in need of modernisation remain deeply embedded in policy making. These open up spaces for the state, investors, and local …

IGC Proceedings (1997-2023)
Limited information exists about the impact of drought stress on corn silage digestibility. The objective of this study was to determine the effect of irrigation on in situ NDF digestibility of corn tissues grown under controlled conditions in a greenhouse. Five commercial corn hybrids were planted in pots and grown in a greenhouse. Pots were subjected to an abundant or restricted irrigation regime. Leaf blades and stem internodes were collected from the upper and bottom portion of each hybrid. Tissue samples were incubated in the rumen of 3 rumen-cannulated cows for 0, 3, 6, 12, 24, 48, 96, and 240 …

Climate change threatens the ability of global rangelands to provide food, support livelihoods and deliver important ecosystems services. The extent and magnitude of potential impacts are however poorly understood. In this study, we review the risk of climate impacts along the rangeland systems food supply chain. We also present results from biophysical modelling simulations and spatial data analyses to identify where and to what extent rangelands may be at climatic risk. Although a quantification of the net impacts of climate change on rangeland production systems is beyond the reach of our current understanding, there is strong evidence that there will …
Exploring Water Use And Production Dynamics Of Indigenous Protected Sikumi Forest In South Western Zimbabwe, O. Gwate
IGC Proceedings (1997-2023)
Monitoring changes in carbon and water vapour fluxes over a landscape helps in understanding ecosystem functioning and improves vegetation management. To understand potential shifts in ecosystem functioning, MoDerate Resolution Imaging Spectroradiometer (MODIS) evapotranspiration (ET), net photosynthesis, gross primary production and net primary production data were explored in Sikumi forest dominated by three species clusters (Teak forest woodland, Miombo woodland and savannah, and Vachellia). Measures of ecosystem stability including water use efficiency (WUE), rainfall use efficiency (RUE), evaporative index, and carbon use efficiency (CUE) were assessed for trends and step changes together with rainfall and evapotranspiration data. Miombo woodland and …

Temperate/Tropical Transition Zones: A Hotspot For Breeding Forages With Climate Resiliency, Kenneth H. Quesenberry, Esteban F. Rios, Kevin E. Kenworthy
IGC Proceedings (1997-2023)
Species resiliency to climate change is critical for sustainability of grassland agricultural systems. Transition zones between temperate and tropical climates (between 27 and 31° N and S latitude) with variable annual frost/freeze events have proven to be ideal zones for identification of species with variable climate adaptation. This paper will identify these regions around the globe and show how these regions offer distinct advantages in terms of selection for abiotic and biotic stresses, and thus resiliency to changing climate. Programs located in these regions have the advantage of exposure to alternating extreme warm and cold temperatures, drought and flood conditions, …

Student Research Symposium
Climatic change is one of the biggest threats to the ecosystem and biodiversity by enhancing environmental stresses. Environmental stresses such as biotic and abiotic stresses affect plant health and reduce crop production. The rhizosphere microbiome of a plant plays a significant role in a plant's defense against various biotic and abiotic stresses. In this study, we are investigating the microbiome diversity of bulk soil, rhizosphere, and endosphere of Ceanothus velutinus, snowbrush. Ceanothus is an evergreen native plant that is usually found in dry areas and thrives well in harsh conditions. The snowbrush samples were collected from different locations 1920m, 1950m, …
