  • Savanna formations: ecology and environment
  • Biogenic process ; Ecosystem ; Environment ; Fauna ; Fire ; Savanna ; Semi-arid area ; Soil properties ; Tropical zone ; Vegetation
  • A number of points can be distilled from this review concerning the current state of research in savannas areas. Work on the dynamics of forest-savanna boundaries and increasing understanding of the rates of change indicate a sensitive response
  • to global, regional,as well as local environmental controls. Savannas are more biologically rich and diverse in terms of soil-plant-animal relationships than generally appreciated. Current research is concentrated in a number of geographic regions, notably
  • the humid savannas of the Venezuelan Llanos, Brazilian cerrado, Guinean and Sudan zones and Nigeria, and the semi-arid savannas.

  • This review indicates that the dominant position of large mammals in savanna studies is being challenged as researchers turn to the not so apparent but significant animal communities present in savannas around the world. Understanding the role
  • of these other taxa will be fundamental for conservation and management practices. Many of which, for example in national parks in the African savannas, are designed to protect large mammals, and not necessarily other animal groups despite their crucial
  • and diverse roles in savanna functioning as pollinators, dispersers, nutrient recyclers and consumers.
  • Tropical savannas and associated forests : vegetation and plant ecology
  • Bibliography ; Biodiversity ; Biogeography ; Ecosystem ; Forest-savanna transition ; Phenology ; Savanna ; Tropical zone ; Vegetation dynamics
  • This review (2002-2006) concentrates upon research relating to plant ecology, examining issues of diversity, boundaries and equilibrium theories, and studies of individual species of tropical savannas and associated forests.
  • Physical and chemical properties of savanna soils in Northern Bolivia
  • Bolivia ; Floodplain ; Forest soil ; Mineralogy ; Savanna ; Soil ; Soil science ; Taxonomy ; Tropical zone ; Vegetation
  • Soil samples from a savanna in northern Bolivia were examined as part of the first detailed study on the regional vegetation. Soil texture, PH, organic carbon, total nitrogen, exchangeable cations, cation exchange capacity, and base saturation of 29
  • The development of savanna afforestation in Northern Nigeria
  • Although eighty per cent of the land area of Nigeria is covered with savanna woodland, there is a shortage of wood and wood products. The Savanna Forestry Research Project has studied the conditions necessary for increased tree growth. Some problems
  • Fire in the cerrado (savannas) of Brazil : an ecological review
  • Biodiversity ; Biogeography ; Brazil ; Ecology ; Environmental management ; Fire ; Savanna
  • Fire is a major determinant of cerrado (savanna) vegetation in Brazil, and is used as a management tool during the dry season. This article reviews past and present fire ecology studies in the cerrado, (abiotic, biotic, social studies and management
  • Tropical savannas
  • Adaptation ; Bibliography ; Biodiversity ; Biogeography ; Environmental conservation ; Fauna ; Man-environment relations ; Research ; Savanna ; Soil properties ; Tropical zone ; Vegetation
  • This review (2000-2005) focuses on the environmental determinants of savanna vegetation and its structural composition, the links between soils and vegetation, and concludes with some of the recent studies on biodiversity and conservation.
  • Geomorphology and soils of Sipaliwini Savanna, South Suriname
  • A description of the landscape system of Sipaliwini Savanna. The relation between geomorphology and soil development is stressed.

  • In search of an approach to the management of savanna fallow soils
  • A comparative analysis of savanna fallow soils in the Ibarapa Division of Oyo State suggests that there is no universal solution to their management. Where soils and environmental conditions vary productivity will vary even where fertilizers
  • The vegetation resources of Botswana's Savannas : an overview
  • Sustainable utilisation of Savannas in Botswana
  • Botswana ; Ecosystem ; Environment ; Natural resources ; Resource management ; Savanna ; Sustainable development ; Vegetation
  • The current status of the vegetation resources of Botswana's savannas is evaluated. However, a lack of systematic data providing sufficiently detailed information on vegetation cover has meant a reliance on site specific data making, making national
  • Sustainability of traditional agriculture in the southern African Savannas of Botswana
  • Sustainable utilisation of Savannas in Botswana
  • Agricultural practice ; Agriculture ; Botswana ; Livestock farming ; Resource management ; Savanna ; Soil conservation ; Sustainable development ; Traditional agriculture
  • The paper seeks to describe and discuss the impacts of agricultural practices by communal and traditional farmers on sustainable management of savannas in Botswana. Sustainability is explained from three viewpoints, namely ecosystem sustainability
  • An assessment of the sustainability of the utilisation of Savanna products in Botswana
  • Sustainable utilisation of Savannas in Botswana
  • Agricultural product ; Botswana ; Fuelwood ; Living standard ; Resource management ; Rural community ; Savanna ; Sustainable development ; Wood
  • The majority of Botswana's population use a wide range of savanna products for food, fodder, medicine, fule, building, utensils and income. The poorest households in both rural and urban areas are most reliant on their consumption and trade
  • Water resources in Botswana with particular reference to the Savanna regions
  • Sustainable utilisation of Savannas in Botswana
  • Botswana ; Dry farming ; Natural resources ; Savanna ; Sustainable development ; Water ; Water management ; Water resources
  • Production and development in the savanna regions are primarily determined by interactions between the limitations imposed by ecological determinants (such as rainfall and soil quality) and the management strategies of the specific region. Good
  • The status and fluxing of alkali and alkaline-earth metals in a savanna alfisol under long-term cultivation
  • Agricultural land use ; Agropedology ; Clay mineral ; Cultivated land ; Fertilizer ; Geochemistry ; Nigeria ; Savanna ; Soil degradation
  • This study investigates the impact of soil management on the status and fluxes of alkali and alkaline-earth metals in a savanna alfisol after 50 years of cultivation. The objective is to determine a suitable management practice which can best
  • protect savanna soils against rapid degradation and potential acidification under long-term cultivation.
  • The comparative role of key environmental factors in determining savanna productivity and carbon fluxes : a review with spatial reference to northern Australia
  • Australia ; Carbon cycle ; Carbon dioxide ; Climatic change ; Ecosystem ; Fire ; Northern Territory ; Precipitation ; Productivity ; Radiation ; Savanna ; Temperature
  • For savannas, the key environmental drivers controlling vegetation productivity are water and nutrient availability, vapour pressure deficit (VPD), solar radiation and fire. Changes in these environmental factors can modify the carbon balance
  • of these ecosystems. Here the AA. have reviewed the various environmental controls on the spatial and temporal patterns on savanna carbon fluxes in northern Australia. Such studies are critical in predicting the impacts of future climate change on savanna productivity
