A critical challenge facing the information and communication technology for agriculture development (ICT4AD) arena at present is promoting a sustainable approach for mobilization of scientific and indigenous knowledge. Mobile phone, a commonly available, easily assessable and relatively affordable technology complemented with diverse uses, can pla...

The potential role and significance of mobilization of scientific and indigenous knowledge to promote sustainable agriculture is well recognized. Yet, the inherent features associated with traditional agricultural extension methods and the high costs of information provision act as the major barriers to improving the livelihood of farmers, especial...

Agriculture is the backbone of the Sri Lankan economy and it constantly experiences with advances in technology. Because of the rapid development of Information and Communication Technology (ICT) in the world, each organization or person has to concern their products and services more towards modernized and ICT related manner. This research contrib...

Correct integration of ICTs in agricultural innovation systems can enhance the efficiency, effectiveness, and reach of extension services. This study aimed to develop a mechanism for knowledge dissemination and capacity-building among sugarcane extension officers in Monaragala District using a technology stewardship approach. A participatory action...

Sri Lanka’s Village Tank Cascade Systems (VTCS) have enabled multiple generations of cascade landscape communities to prosper. Today, however, there are multiple threats to the sustainability of these ancient water management systems and the ecosystems and biodiversity that support them. The Healthy Landscapes Project (HLP) aims to address these th...

I The sugarcane industry in Sri Lanka is being severely affected by declining the rate of sugar recovery over time. It is expected to overcome this situation by increasing the use of proper crop management practices (Keerthipala., 2016). The measures should be taken to transfer the knowledge to the sugar companies at the right time to increase the...

This paper applied a stochastic frontier model to measure total factor productivity growth, technical efficiency change, and technical change in tea production in the estate sector in Sri Lanka. Monthly data from 35 tea estates relating to the period 2005 to 2019 were used. Two functional forms with two distributional assumptions were tested. A Tra...

An excessive use of synthetic chemical fertilizer (CF), mostly with low quality standards, has resulted significantly adverse effects from the socioeconomic and environmental points of view.

In this study, the 'Policy Instruments' available to promote Eco-Friendly Technologies (EFTs) in paddy farming over the use of Chemical Fertilizers (CFs) were examined. The key products coming out from a multi-objective multi-phased research project, including 'Bio Fertilizer' (BF) and 'Bio-char' (BC) were of interest. Data were collected by way of...

Lack of financial capability is one of the major constraints faced by paddy farmers. Most farmers use microcredit, through formal and informal sources as an option to overcome such constraints. This study examines the effect of microcredit on the technical efficiency of paddy production in the Anuradhapura district of Sri Lanka using the Cobb-Dougl...

Health, economic and food safety issues are on the increase in Sri Lanka due to the use of more than the recommended amount of chemical fertilizer (CF) in paddy farming. The majority of agrochemicals imported into Sri Lanka are used for rice farming, accounting for more than 70% of total fertilizer use (Herath et al., 2014). However, extreme use of...

This paper reports on a technology stewardship training program to promote ICT leadership development with agricultural extension practitioners in Sri Lanka. Technology stewardship is an approach adapted from the communities of practice literature that recognizes the importance, practically and ethically, of guiding change from within a community....

As a soft landscape material, trees play a central role in landscape designing. People are willing to incorporate trees into the landscape to get the optimum effect. Selecting suitable plants for appropriate locations is one key aspect in landscaping projects. Selection of the best tree for the given location allow it to establish, sustain, facilit...

Annually Sri Lankan government spends nearly US$ 12,000 for the importation of inorganic fertilizer which is the highest expenditure among the intermediate goods import to the country. The frequent and continuous application of inorganic fertilizers into agricultural fields and its impact on human health and the environment are also rising concerns...

Development of credible approaches to share indigenous and scientific knowledge in possession of farmers, especially those engage in rural subsistence agriculture, has become a necessity in order to enhance their competitive edge in agriculture, however, remains as a challenge at present. The concept of Knowledge Mobilization (KMb) has, in the ligh...

This course workbook provides a series of activities and exercises to introduce student practitioners to technology stewardship. It is organized into four sections: Principles and Practices of Technology Stewardship; Engaging your Community and Creating a Campaign; Choosing an ICT platform and Rapid Prototyping; Planning and Managing a Campaign. Th...

Agricultural knowledge plays a pivotal role in the process of transforming the livelihoods of farmers relied on subsistence agriculture. However, development of credible approaches to “share” the indigenous and scientific knowledge in possession of farmers in order to enhance their competitive edge in agriculture has become a challenge at present....

Knowledge plays an indispensable role in the process of transforming the livelihoods of farming communities, especially those who relied on subsistence agriculture. Yet, the inefficiencies and insufficiencies associated with the existing agricultural extension methods and high information transaction costs associated with such mechanisms act as bar...
