Therefore, the number and quality of trained technical and pro- fessional personnel in agricultural meteorology are critical factors since the effectiveness of any agri- cultural meteorology service is determined by the competence and qualifications of its staff. To sustain this service, there is need for qualified personnel ca- pable and willing to play this role. In addition to those employed in the agrometeorological services, much greater knowledge of the subject is needed within both the user and the research communities. This paper presents a selected overview of the cur- rent status together with a projection of the future needs for agrometeorological education and training. Education and training have a common objective, i.e. development of human resources: however, there are specific differences between them. 1.2. The concept of education The Oxford English Dictionary defines education as ‘systematic instruction, schooling or training given to the young and to adults in preparation for the work of life’. Education includes the development of sound reasoning processes to enhance one’s ability to under- stand and interpret information. The concept of ed- ucation, by and large, includes activities directed at providing information, understanding skills, and moral values that are required in the normal course of life. Providing information and skills is not for a limited scope or activity but focuses on a wide range of activ- ities. The main aim of education is to create circum- stances and opportunities for youth and adults to learn, among other things, cultures and natural laws and to acquire skills, including languages, that form the ba- sis for learning, personal development, creativity and communications. Education, therefore, broadens ones scientific base and is usually of long duration. For a professional career in such a multidisciplinary area as agricultural meteorology the educational process must particularly enable practitioners to find and use infor- mation from a range of sciences other than their own. 1.3. The concept of training The Oxford English Dictionary defines training as the training of a person for some particular profession. Training is, therefore, a learning experience that seeks a relatively permanent change in an individual that will improve his or her ability to perform on the job. Training is regarded as a systematic and planned process to change the knowledge, skills and behavior of personnel to achieve the objectives of the organisa- tion they work for. In contrast to education, training is task-oriented because it focuses on the work an indi- vidual performs. Job description or task requirements of a particular job are used to determine the nature of a training programme. Training is, therefore, directed at improving one’s job performance in an organisation. Training is conducted as a result of technological in- novation, when current work standards are not being maintained and when such situations are ascribed to lack of knowledge and or skills among individual per- sonnel in an organisation. Training is, therefore, more specific, job oriented and usually of short duration. Neither education nor training is a one time effort. Knowledge and skills acquisition must be viewed as a continuous process throughout one’s career. It is therefore regrettable that not all requests for education and training fellowships to WMO can be met. During 1997, 307 fellowships were awarded 28 in agricul- tural meteorology and 547 remained unsatisfied 47 in agrometeorology G. Necco, WMO, personal com- munication.

2. Agricultural meteorology — its scope and aims

‘Agricultural Meteorology’ is concerned with dis- covering, defining and applying knowledge of the interactions between meteorological and hydrological factors, and biological systems to practical use in agri- culture, including horticulture, animal husbandry and forestry. Agricultural meteorology is concerned with processes that occur from the soil layer of the deepest plant and tree roots, through the air layer near the ground in which crops and woods grow and animals live, to the highest levels of interest to aerobiology, the latter with particular reference to the effective transport of seeds, spores, pollen and insects WMO, 1981. In addition to an examination of the natural climate, and its local variations, agricultural meteorology is concerned with induced modifications in the environ- ment as brought about, for example, by windbreaks, soil management, irrigation, glass-houses, etc.. It also J. Lomas et al. Agricultural and Forest Meteorology 103 2000 197–208 199 includes the study of climatic conditions of storage, whether indoors or in field heaps, an examination of atmospheric conditions in animal shelters and farm buildings, and the monitoring of environmental con- ditions during the transport of agricultural produce by land, sea or air. The primary aim of agricultural meteorology is to extend and fully utilize our knowledge of atmospheric and related processes to optimize agricultural pro- duction, thus increasing profitability and decreasing risk. The proper application of principles in this sci- ence can lead to improving the quantity and quality of crop and animal production, and to improving food security. A secondary aim of agricultural meteorology is to help conserve natural resources and protect the envi- ronment from detrimental usage. Sustainable human activity is strongly influenced by climatic conditions and variability. The climate often places constraints upon a particular form of land use at a given place and time. Therefore agricultural meteorology has an important role to play in land use planning. Agricultural meteorology, therefore, includes two basic subject areas: 1. Physical sciences — specifically the physics of the atmosphere i.e. meteorology and climatology and soil physics and hydrology; 2. Biological sciences — specifically physiology, ecology and pathology of plants and animals, and associated disciplines of agriculture such as agronomy and horticulture.
