Summary for the COSTECH 9th STICE Special Issue in EAJSTI

 

The East African Journal of Science, Technology and Innovation (EAJSTI) presents to you a special issue from the 9th Annual National Science, Technology and Innovation Conference and Exhibition (9th STICE) organized by the Tanzania Commission for Science and Technology (COSTECH).

 

COSTECH is a government institution under the Ministry of Education, Science and Technology, mandated by the Parliament Act No. 7 of 1986 to advise the government on all matters related to Research, Science, and Innovation and their application in social and economic development. In this context, among other roles, COSTECH coordinates, supports, promotes, and disseminates scientific research, Technology development and transfer, and innovative products. In regard to the dissemination of research and innovation outputs, COSTECH uses dissemination platforms for various targeted audiences. Such platforms include workshops and conferences, journal publication, mainstream media, and social media platforms.

In 2024, COSTECH organized the 9th STICE, held from 2nd to 4th December at the Julius Nyerere International Convention Centre (JNICC) in Dar es Salaam. The conference brought together more than 1,240 participants from about 47 institutions in the country. The participants for the conference were researchers, innovators, policymakers, industry professionals, and development partners. The main aim of the 9th STICE was to increase awareness of the use of science, technology, and innovation in addressing climate change challenges and strengthen resilience against climate-related shocks and risks. Thus, there was knowledge sharing among professional stakeholders, and dissemination of research results and innovation products to policy and decision makers. The theme of the conference was “Harnessing Science, Technology and Innovation to Achieve Climate Resilience and a Competitive Economy in Tanzania.”

The 9th STICE was organized in a stimulating and informative way, with a wonderful array of keynote speakers and invited speakers. Specifically, the conference program covered 7 keynote presentations, 57 keynote speakers, 5 parallel sessions, and 9 side events that facilitated knowledge exchange, strategic dialogue, and strengthened collaboration across the national STI ecosystem. The conference included an exhibition from innovators and technology experts, where about 85 innovators and technologists showcased cutting-edge technologies and innovative solutions. The 9th STICE also inspired 125 primary and secondary school students who participated in the conference and promoted engaging in STEM learning activities, nurturing future scientists and inventors.

The 9th STICE was opened by the guest of honor, Dr. Dotto Biteko, the Deputy Prime Minister and Minister for Energy, on behalf of Dr. Samia Suluhu Hassan, President of the United Republic of Tanzania. Dr. Biteko reaffirmed the National commitment to leveraging STI for addressing climate challenges and achieving the Sustainable Development Goals (SDGs). Key announcements included a TZS 2.5 billion credit guarantee scheme to accelerate the commercialization of innovations and TZS 6.3 billion grants awarded to 19 scientists conducting climate change research. Five exemplary researchers were also honored for their significant contributions to national socio-economic transformation.

The conference achieved extensive national and international visibility, reaching an estimated 13.7 million people through mainstream media coverage and strategic digital outreach. About 76 research papers were presented and discussed by relevant professionals. The comments raised during the breakout session were used by authors to improve their manuscripts, which among them were submitted for publication as a Special Issue of the East African Journal of Science, Technology and Innovation.

This Special Issue captures the scientific research that was presented during the COSTECH 9th STICE event, demonstrating the important role of STI in advancing Tanzania toward a climate-resilient future.
