Tropical grasslands are moderately green during the rainy seasons but the grass turns yellow and eventually dies down during dry periods. vegetation cover and prevailing weather conditions among others. Based on a 20-year baseline climate observation, it is forecasted that maize and other cereal crop yields will reduce by 7% by 2050. This study examined the vertical and spatial variability of selected soil physicochemical properties (pH, SOM, OC, TN, and bulk density) in Kumasi, Ghana, using a stratified random sampling technique. Climate change in Ghana will have wide-reaching impacts on the country.Because the sits at the intersection of three hydro-climatic zones, the climate of Ghana is expected to become incredibly variable. Today's Weather. km. The results showed that in the Guinea Savannah zone, 88.2% of the farmers were males while 11.8% were females. Animals Geography. Oteng-Ababio, M., Owusu, K. & Addo K. A. VEGETATION In line with the rainfall distribution, a wetter south and a drier northern half, there are two broad vegetation types: Forests and Savanna. Vegetation zones divide land according to temperature and precipitation. Annual compendium of Special Events 2010. Rainfall distribution is bimodal in the forest, transitional and coastal zones, giving rise to a major and a minor growing season. (2011) The Vulnerable State of the Ghana Coast: The Case of Faana-Bortianor. There are three principal types of vegetation from south to north occurring in the coastal savanna, in the forest zone, and in the northern savanna zone. This paper examines the onset and cessation dates of the rainy season over Ghana using rain gauge data from the Ghana Meteorological Agency (GMet) over the period of 1970–2012. plant species such as poplar, birch, oak and elm. As a result of this, it is vulnerable to rainfall variability, which tends to have a major impact on the industrial and agricultural production sectors of the country. Ghana’s economy heavily relies on agriculture, which is predominantly rainfed across its agro-ecological zones. Soil samples were collected at three depths (0–15, 15–30, and 30–60 cm) from 161 plots in eight green space types within two urban zones. Shifting cultivation (also known as "slash and burn") is the main farming practice in Ghana, and one of the main causes of tropical forest disturbance and retrogression to secondary forest vegetation in Ghana. The sample was made up of 150 each in the guinea savanna and transition zone and 120 each in the semi-deciduous and coastal savanna zones . The study sites were Paga, Nyankpala and Kawampe, which are located in the transitional and Guinea savannah zones of Ghana. Vegetation plays a vital role in our natural ecosystem and also supports the biosphere in various ways; vegetation helps to regulate the flow of numerous biogeochemical cycles, most importantly those of water, carbon, and nitrogen; it also contributes in the local and global energy balances. Montane vegetation in Nigeria (mountain and plateaus vegetation) is not very developed due to the reason of low average temperatures and the significant impact of animals and man. Geography. There are six agro-ecological zones defined on the basis of climate, reflected by the natural vegetation and influenced by the soils (Table 1). Most gardeners look at a map of vegetation zones before planting any flowers, trees, or vegetables. – The vegetation arranges itself on the slope in clear demarcated zones. In Key Stage 2 (KS2) - Lower. From north to south — from the Sahara to the humid southern coast — West Africa can be subdivided into five broad east-west belts that characterize the climate and the vegetation. Journal of Disaster Risk Studies 3:2 429-442. Ghana - Ghana - Plant and animal life: Although soils and biotic factors (i.e., those pertaining to living organisms, including humans) are important, vegetation is primarily determined by precipitation. There are three variants of each, running as near parallel bands east to west across the country. Vegetation zones, also called hardiness zones, are smaller, more-detailed vegetation regions. Agro-ecological Zones and Climate . A farmer cultivates a piece of land in a year and abandons it for a new piece of land the following year. Except in the north two rainy seasons occur, from April to July and from September to November. Ghana is a West African country with a coastline on the Gulf of Guinea and occupies a total area of 239,567 sq. Table 2 presents the socioeconomic characteristics of maize farmers in the agro ecological zones. The largest is the desert and arid zone, which covers most of northern Africa. The transition and guinea savanna ecological zones have some peculiar socio-economic characteristics and fragile vegetation that make them important candidates for such a study. Variation in Species Characteristics within Communities: Density: Number of individuals per area #/m 2 : Interpretation depends on the size of individuals; sometimes difficult to define an "individual" Frequency: Proportion of plots in which a species is found % Easy to measure The onset and cessation dates were determined from cumulative curves using the number of rainy days and rainfall amount. The Transition zone also recorded 76.4% for males and 23.6% for females. It is a rectangular-shaped country bordered to the north by Burkina Faso, the east by Togo, the south by the Atlantic Ocean and the west by Côte d'Ivoire. The Montane zone is situated in high-mountain areas. sustainable use of bamboo in national development in Ghana. Characteristics of the Temperate mountain vegetation – Temperate mountain vegetation contains both deciduous and coniferous. Proceedings of the Ghana Academy of Arts and Sciences Issue Number 9964-950-42-X. Ghana is a West African country in Africa, along the Gulf of Guinea, just a few degrees north of the equator.. Ghana encompasses plains, low hills, rivers, Lake Volta, the world's largest artificial lake, Dodi Island and Bobowasi Island on the south Atlantic Ocean coast of Ghana. 28. Together the three kingdoms were known as the Sahelian Kingdoms. These are the bioclimatic zones known as the Saharan, Sahelian, Sudanian, Guinean, and … We addressed this question by determining the prevalence of tick-borne pathogens within three vegetation zones of Ghana (Fig 1). – Some trees species grow a thick bark in order to store enough water to be. The African rain forest – main characteristics of changes in vegetation and climate from the Upper Cretaceous to the Quaternary - Volume 104 - Jean Maley Skip to main content Accessibility help We use cookies to distinguish you from other users and to provide you with a … A 1 page worksheet for students to use when learning about different vegetation zones around the world. The United States, for example, is usually divided into 10 vegetation zones. Ghana vegetation is about the different farming activities. As one moves from the tropical savanna climate into desert regions, the vegetation is dominated by dwarf acacias and scrubs. FIGURE 1 : MAP SHOWING THE COASTAL ZONE OF GHANA • MAP COASTAL ZONE AKArmah 2004AKArmah 2004 Introduction • The coastal zone may be divided into three geomorphologic zones: – West Coast, 95km, fine sand, gentle beaches, coastal lagoons. As observed on the map above, Ghana is dissected by the largest artificial lake on the planet (Lake Volta), nearly 50% of Ghana lies less than 152 meters above sea level. Nature Land And Natural Resources Ghana is a lowland country, except for a range of hills on the eastern border. Ghana is composed of six agro-ecological zones (Figure 2) distinguished by natural vegetation and influenced by climate and soil characteristics. Forestry Research Institute of Ghana is one of the 13 institutes of the Council for Scientific and Industrial Research (CSIR). Ghana is situated in West Africa between latitudes of 4°N and 12°N, and longitudes of 4°W and 2°E. It started as a research unit within the Forestry Department in 1962. The climate of Ghana is tropical, but temperatures vary with season and elevation. The three ancient kingdoms in West Africa included Ghana, Malii and Songhay. There are various types of vegetation in Sierra Leone. defined by a dissected plateau with rivers draining into Lake Volta (aquastat – Ghana 2005). In some regions, the elephant grass species may grow to 15 feet tall. Figure 2: Ecological Zones Map of Ghana 1.1.4 Soils The characteristics of the soils of Ghana are influenced by local climate and vegetation, including other organisms, which act on the various geological materials as modified by local relief or topography over periods of time. The wet period for that zone lasts just three months, which results in little to no vegetation. Table 18: Identified Soil Groups in the Volta River Basin of Ghana Table 19: Characteristics of the Zones Table 20: Major landuse types in the Volta basin of Burkina (hectares) Table 21: Erosion Hazards of the Volta Basin in Ghana Table 22: Rate of Occupation of Cultivable Land in the Basin in Togo (1,708,800 ha) The four main climate zones of Africa are semi-arid, desert and arid, subhumid and humid. Information on sources, potential and perceived uses of bamboo as well as constraints in the bamboo sector were obtained through structured questionnaire and semi-structured interviews from locations spreading across all major ecological zones of Ghana. Table 3 also presents the descriptive statistics of farmers’ characteristics and quantities of inputs and outputs. The Jos plateau is one of the highest points in Nigeria. It is located at Fumesua near Kumasi in the Ashanti Region of Ghana. These areas are located entirely within the tropics (between 4° and 12°N, 4°W and 2°E) and are considered to have a tropical climate at the national level as characterized by high mean temperature and rainfall.
