Knowledge, Perception and Adaptation Strategies to Climate Change among Farmers in Southern Agricultural Zone of Nasarawa State, Nigeria
ES Salau, EG Onuk, A Ibrahim
Journal of Agricultural Extension , 2012,
Abstract: Climate change is perhaps the most serious environmental threat facing mankind worldwide. The study was designed to assess the knowledge, perception and adaptation strategies to climate change among farmers in southern agricultural zone of Nasarawa state. The specific objectives were to: identify the sources of information on climate change by respondents; assess their knowledge and perception of climate change phenomenon; identify adaptation strategies used and the factors militating against their adaptive capacity. A multi-stage sampling procedure was used to select a total of 150 respondents from the zone for the study. Data collection was through an interview schedule. Simple descriptive statistics such as frequency, percentage and mean scores were used to achieve the objectives. The null hypothesis was tested using a multiple regression model. The mean age of the respondents was 48 years. Majority (89.33%) of them were males while their average farming experience was 27 years. Most (38%) of the farmers in the area had no formal education and majority (76.7%) of them used inherited farmlands. Annual income level of the respondents was encouraging with a mean of N326, 461.30 per annum. Most (68%) of them relied on radio as their major source of information on climate change. The perceived indicators of climate change included excessive high temperatures, low and irregular rainfall pattern and low crop yields among others. Adaptation strategies used by the respondents included agro-forestry practices, crop diversification, use of organic manures, planting of early maturing and disease/drought resistant varieties. The major constraints to adaptation by the respondents were inadequate finance, poor infrastructures, unfavourable government/trade policies and poor technology. It was recommended that adult education programmes should be strengthened in the area to reduce illiteracy among farmers. Extension agents in the area should incorporate climate change information in their extension messages while government should intensify efforts in the area of integrated rural development.
APAC: An exact algorithm for retrieving cycles and paths in all kinds of graphs
Sim?es,Ricardo;
Tékhne - Revista de Estudos Politécnicos , 2009,
Abstract: this paper presents an alorithm for retrieving all paths and all cycles between two vertices in random directed or undirected connected graphs. this algorithm can be easily implemented and is highly modular; with minor changes it can be adapted to obtain different parameters from the graphs. it is also demonstrated that the complexity of the algorithm increases linearly with the number of paths. the algorithm can be used in a myriad of applications. aside from calculating all the paths and cycles in a graph, it can be used to calculate all the paths with length l between two vertices in the graph, as well as a solution to the clique decision problem. thus, it has applications in computer networks, material science and electric networks, as well as in any problem where it is necessary to know the number of paths (not the optimal paths) in a directed or undirected connected graph or in multigraphs. the algorithms currently available in the literature, such as the depth-first search (dfs), are unable to solve this type of problems in a straightforward way.
