    This case study was conducted to provide a good understanding of the challenges and opportunities related to Egypt’s agricultural research and organizational development to draw lessons and develop supporting guidelines. This study aimed to enhance efforts exerted by Egypt’s NARS in the field of developmental research by formulating an integrated and coherent approach for research and dissemination of proven technologies and practices. Such approaches are expected to address key bottlenecks and provide the needed direction and means for sustainable improved implementation of AR4D. This can ultimately lead to enhancing and empowering the capacity of Egypt’s NARS to better inform and influence policies and facilitate institutional changes required in the agricultural sector. As part of the efforts of the Food and Agriculture Organization of the United Nations (FAO) to support and strengthen NARS’ research impact and their links to extension service systems, the present assessment was carried out to establish a deeper insight into challenges and opportunities that are facing NARS in Egypt.

    Three workshops on Trickle Down Extension System (TDES) of 2 days duration each, were conducted at Rajshahi, Khulna and Dhaka Divisions during September and October 1992. Main objective of the workshops was to bring clarity among the participants about the concept of TDES. Progress and production performance made in fish culture by the Result Demonstration Fish Farmers (RDs) and problems encountered during operation have also been reviewed. Consequently these participatory workshops helped in im proving functional design and the strategies of TDES by incorporating the recommendations made by the participants. Three such workshops were organized at Bogra, Jessore and Mymensingh where a total number of 62 RDs and 100 Officers/Staff/Resource persons actively participated. Recommendations formulated during the workshops on different aspects of the TDES have properly been recorded in this report. The TDES has been introduced in 34 Thanas of 10 Districts under 4 Divisions. During October 1990 to September 1992, the number of RDs increased from 156 to over 450. At present, a total number of 3552 Fellow Fish Farmers (FFs) are linked with 450 RDs. The fish production rate in RDs pond increased from 980kg to 3373kg/ha/yr, 932kg to 3915kg/ha/yr and from 661kg to 3239kg/ha/yr in Rajshahi, Khulna and Dhaka Divisions respectively. The average benefit cost ratio of the beneficiaries (RDs) ranged from 1:1.94 to 1:3.85 in Rajshahi Division, 1:1.55 to 1:2.65 in Khulna Division and 1:1.48 to 1:3.80 in Dhaka Division. On the other hand, there was marked fall in the average production cost of fish. It came down from Tk.20.59 to Tk.8.69, Tk.21.98 to Tk.9.47 and Tk.28.00 to Tk.9.33 in Rajshahi, Khulna and Dhaka Divisions respectively.

    No results found.

    As part of the efforts of the Food and Agriculture Organization of the United Nations (FAO) to support and strengthen NARS’ research impacts and their links to extension service systems, the present assessment was conducted in Liberia to establish deeper insight into these challenges and opportunities. The results presented in this comprehensive report can be used to support the development and adoption of guidelines for use by the NARS. The present study was undertaken to assess the implementation of AR4D in Liberia and the key actors involved to better understand the performance and the intuitional linkages amongst them and other relevant institutions to help identify potentials for fulfilling the agricultural research for development needs of the country with the over-arching goal of supporting small-scale farmers.
