Multi-Strata Silvipastoral Systems For Increasing Productivity And Conservation Of Natural Resources In Central America, Muhammad Ibrahim, Andrea Schlonvoigt, Juan Carlos Camargo, M. Souza

IGC Proceedings (1997-2023)

Conversion of primary forest to pasture is widespread in Central and Latin America and the progressive removal of trees has resulted in environmental degradation and a decline in productivity, simultaneously threatening rural livelihoods and regional biodiversity. Recently there has been keen interest to develop silvipastoral systems for sustainable animal production. Traditional silvipastoral systems are characterised with a diversity of woody perennials that plays an important role in supplying feed to animals in the dry season, production of timber, shade for animals, and in the conservation of natural resources. Improved novel woody perennials such as Morus alba (mulberry) and Trichanthera gigantea …

Remote Sensing And Gis Techniques For Forage Production Assessment And Management Of Northern Chhattisgarh In India, Nur Salim Ekka, S. K. Gupta

IGC Proceedings (1997-2023)

Grasslands play a vital ecological and environmental role in global carbon balance and climate change. In the prairie provinces of Canada, grasslands occupy approximately 25 M ha of the land base and provide a valuable resource to the multi-billion dollar cattle industry. In recent years, remote sensing technology has been applied for estimating the fractional cover of arid grasslands and savannah ecosystems (Asner and Heidebrecht, 2003; Marsett et al. 2006; Guerschman et al., 2009). Grassland, a specific ecosystem, occurs naturally on all continents excluding Antarctica (White et al., 2000). Remote sensing imagery needs to be converted into tangible information …

Changes In The Economy And Ecology At Proposed Lake Sites In The Salt River Basin, Kentucky, During Early Construction Of The Dam For Taylorsville Lake, Louis A. Krumholz, Stuart E. Neff, Edmond J. Bacon Jr., John R. Baker, Daryl E. Jennings, Andrew C. Miller, Vincent H. Resh, David S. White

KWRRI Research Reports

This is an extension of the work reported in Project numbers B-005-KY, B-016-KY, and B-022-KY that extended from 1 July 1968 through 30 June 1972. Permanent collecting stations have been established at 67 sites throughout the Salt River, Beech Fork, and Chaplin River drainages. Turbidities increases quickly as flow and runoff increase, and subside quickly when the rain stops. Suspended solids range up to 1,700 mg/l in high turbidities and vary considerably as a result of local spates. Water chemistry generally reflects the limestone nature of the substrate and physico-chemical characteristics of a typically healthy limestone stream. Bottom organisms are …

A Detailed Investigation Of The Sociological, Economic, And Ecological Aspects Of Proposed Reservoir Sites In The Salt River Basin Of Kentucky, Stuart E. Neff, Louis A. Krumholz, John R. Baker, Daryl E. Jennings, Andrew C. Miller, Jerry S. Parsons, Vincent H. Resh, David S. White

KWRRI Research Reports

Samples of water, bottom fauna, and fishes were collected from 66 stations in the Salt River and one of its principal tributaries, the Beech Fork and its tributary, the Chaplin River, Kentucky. Precipitation ranged from 38.86 inches (1969) to 58.04 inches (1970), an increase of nearly 50 percent with marked fluctuations in discharge. Intensive comparisons of phosphates, sulfates, specific conductance, total alkalinity, total hardness, and turbidity showed the streams to be relatively clean and healthy. Nearly 300 different kinds of benthic organisms and other macroinvertebrates have been collected and identified from the basin. Detailed studies of caddisflies and stream drift …
