Quality Seed Production And Effective Marketing Systems For Development Of Grasslands, M. Philip Rolston
IGC Proceedings (1977-2023)
Seed quality is defined as (i) maintaining genetic purity using seed certification principles (generation system; isolation; previous cropping history); (ii) achieving high levels of physical purity (especially low weed seed levels) by in field weed control and seed cleaning; (iii) achieving high levels of seed germination at harvest and maintaining germination through the seed supply chain. Seed production systems must not only produce high quality seed but also achieve economic seed yields. Seed crops have to be profitable (by being high yielding) to justify the investment of time and input costs to achieve quality. This in turn requires supporting research …

Scouting Benefits And Developing Innovations In Temperate Grassland To Sustainable Agriculture Production, Walter Ayala, Ethel Barrios, Ignacio Macedo, Jorge Sawchik, José A. Terra
IGC Proceedings (1977-2023)
Agricultural intensification raises concern about land use and future effects to natural resources. The world demand for grain, meat and forest products is increasing constantly. Changes are occurring at large scale, being a compromise for policy makers to contribute to identify opportunities to readdress the productive scenario. There is available technology to reduce impacts, without restricting necessarily productivity. Grasslands provide a large series of economical and ecological benefits to the agricultural systems, being the literature exhaustive in examples. Ley-farming and cover crops technologies are good examples of environmentally sound soil management practices. The society is also worried about an improper …

IGC Proceedings (1977-2023)
The profitable and sustainable management of livestock production from grassland systems is challenging and it can be difficult to develop a research structure that addresses farmer’s needs and has acceptable rigour and on-ground impact. This paper describes the attributes of research, development and extension (RD&E) programs that are required for a successful partnership between researchers, farmers and advisors. Insights are provided from the EverGraze program that designed, tested and implemented farming systems based on perennial pastures across southern Australia. With this project farmers and advisors were involved in setting research direction, designing experiments, providing strategic guidance over the management of …
Ecologically And Socially Sustainable Livestock Development In Marginal Areas,

Ecologically And Socially Sustainable Livestock Development In Marginal Areas, Ilse Köhler-Rollefson
IGC Proceedings (1977-2023)
“Marginal areas” are perceived as difficult and unproductive landscapes, always under the threat of drought, desertification and poverty. Yet, both dryland and high altitude marginal areas have an extraordinary output of livestock products; in the efficiency of producing human-edible protein they far surpass more fertile areas. This productivity under adverse climatic conditions rests on sophisticated strategies and social institutions developed by pastoral communities to deal with variability in the availability of resources. It depends on the use of animal genetic resources that are adapted to make best use of local vegetation and can cope with seasonal variations in availability. Livestock …

Valuing Variability--New Perspectives On Climate Resilient Dryland Development, Saverio Kratli
IGC Proceedings (1977-2023)
Valuing Variability is a challenge to the view of the drylands as naturally vulnerable to food insecurity and poverty. It argues that improving agricultural productivity in dryland environments is possible by working with climatic uncertainty rather than seeking to control it – a view that runs contrary to decades of development practice in arid and semi-arid lands.

Participatory And Holistic Approaches With Grassland Farmers And Development Of Policies, Alain Peeters
IGC Proceedings (1977-2023)
The world is changing rapidly. Grassland farmers and ruminant livestock breeders will have to adapt to these changing environmental, social and economic conditions. Research can help them at the condition that linear ‘top-down’ technology transfer methods are abandoned for the benefit of participatory and holistic approaches. These approaches classified in the generic term of ‘Farming System Research’ consider farmers as real research partners, and they merge farmer’s and scientist’s ideas with those of other stakeholder types. They combine scientist’s and farmer’s knowledge for creating fast innovations, easily adopted by farmers since farmers themselves contribute to their design and their development. …

Sustainable Grasslands: Resolving Management Options For Livelihood And Environmental Benefits, David R. Kemp, Warwick B. Badgery, David L. Michalk
IGC Proceedings (1977-2023)
To help solve the major issues of improving livelihoods and environmental services, grassland research needs to be evaluated within the context of relevant farm systems. Treatments need to show that they not only have significant effects but that they have effects that are meaningful in the context of the relevant farm system. Research often defines an optimum criterion for management that is a single point, but that is difficult to achieve in practice, especially when there are several components in a grassland system that need to be optimised. It is argued that an appropriate criterion for optimising management is a …

Climate Change Impact And Adaptation In Temperate Grassland And Livestock Industries, Afshin Ghahramani, Andrew D. Moore
IGC Proceedings (1977-2023)
Climate is projected to have negative impact on temperate grassland and livestock productions across the globe. Moderately elevated atmospheric CO2 in the near future is expected to increase plant photosynthetic rates but this is likely to be limited by soil nitrogen deficits. However, in Australia at least it is unlikely that positive effect of elevated CO2 on plant production be able to offset the negative impacts of climate change. Currently there is a considerable gap between actual and achievable production and profit in Australian grazing systems and many management and genetic improvements for climate adaptation would operate by …

IGC Proceedings (1977-2023)
Brachiaria grass is an important tropical forage of African origin with desirable attributes of agricultural and environmental significance. Brachiaria has been extensively cultivated as a pasture across the tropics except in its endemic provenance of Africa. In 2013, a collaborative research program was initiated in Kenya and Rwanda with the aim of improving the availability of quality livestock feeds adapted to drought and low fertility soils using Brachiaria. The outcomes sought were increased livestock productivity leading to improved farmer income and the development of seed production opportunities. The program has identified five preferred cultivars, and four of them are currently …

Grasses are unique group of flowering plants that form the foundation for the trophic structure in terrestrial communities. The grasses are found in every conceivable habitat where plants can thrive – from sea to deserts and from wetlands to peaks of highest mountains. The grasses form a distinct biome – a major ecological formation in the global classification of vegetation.

IGC Proceedings (1977-2023)
Germplasm enrichment in major tropical grasses and their characterization for emerging environmental challenges have been major focussed area in the recent past. Breeding efforts in tropical grasses are still limited to few selected species viz. Panicum spp, Cenchrus spp, Pennisetum spp and Bracharia spp and all other grasses use of land races for varietal development through selection have been major source of improvement. The pace of breeding efforts in the tropical grasses have been slowed because of many inherent characteristics viz. apomixis, poor seed set, high photo and thermo sensitivity often creating problem in designing and implementing an effective breeding …

Sustainability, Biodiversity And Environmental Issues: A Global Perspective For Livestock Production, David L. Michalk
IGC Proceedings (1977-2023)
To meet world food demand through the 21st century, agricultural production needs to increase, but this needs to be done sustainably through increasing efficiency, optimising sufficiency and achieving consistency, such that resource use is optimised, waste reduced and environmental benefits gained. These strategies need to be developed against changing food patterns, especially a decline in per capita consumption of cereals and an increase in meat consumption as household incomes increase. Grasslands are collectively the larger group of land-based ecosystems on the planet. Their values are not always recognised, often being seen as ‘reserves’ for exploitation for urban expansion, …

Grassland And Livestock Production: The East African Case, David Miano Mwangi
IGC Proceedings (1977-2023)
Grasslands cover over 26% of the world land mass and about 80% of the agricultural area. They are the source of a livelihood for about 1 million people in the developing countries. Livestock contributes 40% of the global value of agricultural outputs. Approximately 60% of rural households keep livestock. In East Africa there are a number of grasslands. The most extensive of these are the Acacia based Savanna grasslands. Others include the sudd flooded grasslands of South Sudan and the Miobo woodlands of Tanzania. More than 60% of the livestock and wildlife in this region are found on these grasslands. …

Three Is Company: Fixing The Grazing-Land Business Conundrum, Ralph Von Kaufmann
IGC Proceedings (1977-2023)
Grazing-lands have the largest footprint on the world’s land surface area but this is not reflected in the amount of business conducted on them. The most common land use systems are very land intensive, i.e., they use a lot of land to produce not very much and few jobs. The health of the planet depends on having healthy grazing-lands but there is a perfect storm brewing in which the demand from expanding pastoral communities for more food and jobs cannot be met just by applying good grazing-land management practices. Compatible businesses must be found that can create jobs without increasing …

Evaluating Physiological Responses Of Ten Alfalfa (Medicago Sativa Subsp. Falcata) Germplasm To Drought Treatments, Austin Hanson
The Journal of Undergraduate Research
Alfalfa is the most widely produced perennial forage legume in North America. However, its use in the semiarid northern Great Plains is limited due to poor stand establishment and persistence under drought condition. The development of drought-tolerant alfalfa cultivars is of great need. Some Medicago sativa subsp. falcata populations have demonstrated promising drought resistance when compared to M. sativa. Morphological and physiological mechanisms play a critical role in drought tolerance by influencing seedling survival, stand establishment and drought recovery. Assessment of variability in physiological responses to drought among germplasm lines to drought is necessary for developing cultivars with improved drought …
