Abstract:

Purpose The purpose of this paper is to explore the effect of agricultural extension services provided by public sector on the individual technology adoption behaviour of rice farmers in Sri Lanka. Design/methodology/approach The study used data from a cross sectional survey conducted in seven rice procuring regions in Sri Lanka. Eight rice technologies were selected to explore the effect of extension service on adoption behaviour of rice farmers using probit models. The extension service variable was identified as potentially endogeneous and instrumented using average extension for each region. Findings The results revealed that the extension service variable was positive and indicative of a high level of significance in all the rice technologies promoting the adoption. Hence the public agricultural extension service programmes were considered as significant explanators of technology adoption. The farmers who received agricultural extension service were more likely to adopt a technology. Social implications At present, the position of agricultural extension service is questioned and the future is unknown. Therefore, this study advises policy makers to prioritise agricultural policies to strengthen public spending on agricultural extension for effective adoption of technological innovations. Originality/value The paper adds solid empirical evidence to the literature on technology adoption behaviour from a peasant agricultural context in a developing country scenario that uses farm level data. Moreover, the study contributes to the literature by reiterating the significance of public provision of extension and training programmes as a direct motive in the technology adoption behaviour of farmers.

Abstract:

SummaryOrganic agriculture has the potential to reduce the negative impacts of conventional agricultural practices and enhance rural economic development. Since research on Sri Lankan farmers’ attitude towards organic agriculture has been rare, this research aims to explore the farmers’ viewpoint on organic agriculture. Two main rural districts were purposely selected for this investigation since these districts have a high potential for organic agriculture. Two Divisional Secretariat (DS) divisions from each district and 75 farmers from the farming community of each DS division were randomly selected to form a sample of 300 farmers. Data were collected from July 2017 to April 2018 and analyzed using descriptive statistics and binary logistic regression. The results revealed that a majority of the farmers (74%) were well-aware of organic agriculture and agricultural extension programs, while training was the primary information source in both districts. As per the mean analysis, the farmers had a positive attitude towards health-related and environmental protection aspects. However, they had a negative attitude towards the complexity of organic agriculture and unavailability of a suitable market for organic products. Results of the binary logistic regression revealed that the education level of the farmers significantly affect their attitude towards organic agriculture. The availability of traditional knowledge and technology relevant to organic agriculture, favorable climatic condition, and some government support were the main potentials, while labor intensiveness was the main challenge. Thus, creating better marketing facilities for organic products, providing the required amenities for producing organic food, processing, and value addition will promote organic agriculture among more farmers, supporting sustainable development.

Abstract:

AbstractSri Lanka is an island country located in the Indian Ocean, characterized by tropical weather, with an estimated population of 21.4 million in 2017, one third of them being children. Advancing and rapidly changing technology, novel industries, consumer goods and equipment have introduced new health hazards of a chemical, biological and physical nature to future generations. The infant mortality rate has declined to around 8–9 per 100,000 since 2015. Congenital malformations were the most significant cause of neonatal death. Thus, there might be unproven environmental factors which affect infant mortality rates despite robust field and hospital services. Air pollution is a major environmental health hazard to children, largely due to hazardous industries, vehicular emissions and traditional cooking stoves. The health of children living in urban households and attending schools in cities is adversely affected by air pollution. Usage of polythene and plastic for toys, utensils, bags, lunch sheets and other daily essentials leads to overusage and improper waste management and open burning. This emits dioxins, which are carcinogens, hormone disruptors, and which can be transferred to the fetus via the placenta. In rural areas, the burning of agricultural waste and certain agro-forestry activities have also led to air pollution. Indoor air pollution (IAP) remains a large threat as 66% of the population use biomass for cooking. Use of inefficient stoves and biomass, poor ventilation and absence of chimneys, contribute to IAP. Other indoor air pollutants such as tobacco smoke, volatile organic compounds, asbestos, pesticides, kerosene, mercury, mosquito coils and biological pollutants also prevail. Biological pollutants, such as dust mites, droppings and urine from pets, insects and rodents, pollen from indoor plants and outdoor air, and fungi, including moulds in poorly maintained buildings, can trigger asthma or cause allergic reactions and infections among children inhabiting these environments. In rural areas, chemicals were accountable for 30.2% of acute poisonings, with kerosene oil being the most common cause, followed by paracetamol. More than 80% of agricultural workers in the country work in the informal sector with limited personal protective equipment use, while pesticide usage is increasing. Children who engage in agriculture-related work and hazardous industries are at risk of developing health consequences at early stages. Dengue remains a major environmental health problem as the reduction of mosquito breeding sites has been a challenging task for many years. It is essential to gain more evidence of existing environmental risk factors and their associations with the health of children. Information dissemination among local and international experts on Children’s Environmental Health (CEH) issues needs to be enhanced and properly established. Training programs should be conducted for healthcare workers to update their knowledge. Pediatricians are needed for remote hospitals and primary healthcare centers. Environmental parameters and biological parameters are not routinely monitored in most of the hazardous environments.

Abstract:

It is well-known that traditional methods of technology dissemination are not cost-effective; and that extension agencies are limited very much by personnel resources in approaching the clientele they need to contact. Therefore, at present, many sectors of the world economies are attracted to the use of ICT for technology dissemination. However, such interventions are not common in the agricultural sector, especially in developing countries. Realizing this, the Department of Agricultural Economics and Extension at the University of Ruhuna, Sri Lanka, implemented a programme ‘Lifelong Learning for Farmers’ (L3F), employing ICT as one of its components. For this programme, the University of Ruhuna collaborated with the mobile phone company Mobitel(PLC) Ltd and developed an IVR (interactive voice response) system to approach clients. Mushroom production is essentially small-scale and remains a cottage industry. In order to raise the living standards, it is necessary to provide scientific information to scattered production units. Such efforts will turn them into commercial producers and provide an opportunity to compete in the local and foreign markets. This investigation focuses on the use ofmobile phones for technology dissemination to small-scale mushroom producers. The IVR system embedded different two-minute messages employing ODL techniques over six months. The entire series of lessons included the establishment of a mushroom shed; the preparation of the growing medium; filling bags and sterilization; inoculation and incubation of mushroom spawns; harvesting; pests and disease control; processing and preservation; seed production; and business planningand financial management. The results showed that 5,583 clients listen to the lessons; and, according to the spatial distribution, the majority of them were from wet zone districts as the climatic conditions are favourable for the enterprise. However, feedback is still limited.

Abstract:

In 1999 85 % of the milk and milk products consumed in Sri Lanka were imported at a cost of over 7000 m rupees. While this appears to offer a major opportunity for the national herd to improve production, indiscriminate deforestation, reduction of farm size and increased use of agricultural land for crop production has tended to depress both cattle numbers and production. Poor nutritional status of the animals is the major limiting constraint, caused by the inadequate supply of quality feedstuffs and confounded by the lack of advice from the poorly supported agricultural extension service. In addition little detailed information exists concerning the nutritive value of the majority of Sri Lankan feeds. Three in vitro techniques – the Minson and McLeod (1972) version of Tilley and Terry (T&T), the modified ANKOM (ANK) batch culture technique (Mould and Nordheim, 1998) and the RPT methodology (Mauricio et al., 1999) were compared in an effort to identify a suitable system to investigate Sri Lankan feeds. The degradation characteristics of rice straw were investigated in this study as, while nearly three-quarters of Sri Lankan cattle and buffaloes are reared in arid zone where rice straw is the major crop residue, only a small proportion is offered as feed.

Abstract:

Background: Paddy cultivation is a major occupation in informal sector in Sri Lanka. In 2014, contribution of the agricultural activities to the country’s annual GDP was 9.9% of which, contribution by paddy was 11.3%. The objective of the current study was to describe the work environment in rice mills with respect to dust, humidity and thermal condition, ventilation and illumination.Methods: A cross sectional study in 107 randomly selected rice mills was carried out in Ampara district in Sri Lanka. Standardized measurements were carried out to assess internal work environment of the mills.Results: Milling activities showed a seasonal variation. The majority of the mills (95.3%) manufactured raw rice only. Other than the basic characteristics, both automated (AMs) and non-automated mills (NAMs) showed common features. All rice mills exceeded the threshold limit values for total (520.04 mg/m3, SD=191.86 mg/m3) and respirable dust (48.14 mg/m3, SD=9.4 mg/m3). Mean daytime indoor relative humidity in the majority of the mills (n=102, 95.3%) was within the accepted upper limit. In most of the mills, ventilation (n=84, 78.5%) and illumination in polishing/packing area (n=60, 56.1%) was satisfactory while in dehusking/paddy inlet area (n=96, 89.7%), illumination was below the limits.Conclusions: Work environment in both the AMs and NAMs in Ampara district presented with poor work standards compared to the required guidelines.

Abstract:

Demining is calamity of third world countries. The clearing is ceaseless, more expensive than the spreading, and terrorist return is obtained by weakening of the antagonistic population. The mines are cheapest weapon, built to make horrible injuries, affecting active people, with major falls-off into economic growth. The disaster is notably cruel in Sri Lanka, with anti-person mines spread in the northeast region. After the ceasefire, the international organisations started the mine sweeping, with poor issues, due to politico-economical motivations in direct bond with wants in the technical effectiveness. The pitiable situation is worsened, as most rich lands are removed from farming exploitation, with increasing of the internally displaced persons. Now, clearing is engineering duty, and the humanitarian goal comes to be technical challenge. The advanced robotics fulfils clean and reliable tasks, on condition to upgrade sophistication and cost and to loose third-world appropriateness. The challenge is to turn local machines and awareness into effective robotic aids, willingly used by the local people, and to enhance the on-going outcomes. The analysis, mainly, addresses the following points: - the engaged technologies need to provide special purpose outfits and to involve operators having adapted uniformity; - the work-flow pre-setting ought to detail the duty-cycles and to establish the standard achievements; - the planning has to specify the on-process warning/emergency management and the failure protection rules; - the operators’ instruction and training shall aim at off-process optimised work-flows to circumvent risky issues; - the effectiveness comes from organised routine agendas, in conformity with allotted tasks and emergency events. This is a mix of organisational and technologic demands, calling for responsible commitment of the involved people, so that the local Civil Service is entitled to do the clearing operations, and the all engaged community is solidly concerned. The winning solution shall look at low-cost robotic outfits, to be obtained with resort to nearby available resources and competences (e.g., drawn on from the local agricultural machinery and know-how), and full account of the cost limits, while aiming at the process effectiveness by the mix of enabling cues, principally deferred to enhancing the regional awareness and the factual dedication. The paper stresses on fairly unorthodox robots, addressing unmanned effectors facilities joined with intelligent remote-command abilities, not as advanced achievements, rather as cheapest productivity upgrading, assembled from standard farming devices, through the shared know-how and commitment of locally involved operators.
