This site provides access to a suite of climate related observations, projections and predictions for the African continent. Of particular interest are the up-to-date seasonal predictions and the African monsoon bulletin. There is also a searchable archive of climate data and research activities detailed in French. ACMAD also offers 'on the job training' in climatology. The website is also available in French.

The African Journal of Biotechnology is a peer-reviewed online journal that publishes research in food, agricultural and industrial applications of biochemistry, microbiology, genomics and proteomics.

All articles are free to access and readers can also sign up to free email alerts containing the table of contents for each new issue.

AJFAND is an academic journal — published quarterly — by the Rural Outreach Programme, a non-profit company based in Kenya. The journal's free-access website features peer-reviewed articles about poverty, food security, disease and agriculture in Africa. It also provides commentaries, short communications, book reviews, and relevant news and events. Students can submit work to the student section.

AJOL is an online database that hosts more than 400 peer-reviewed, African-published research journals. Over a quarter of these journals are open access. The website provides access to tables of contents, abstracts and links to full-text articles in PDF format, as well as author guidelines and contact details for each journal. It also provides useful resources for researchers and publishers.

AMMANET promotes using genetic marker-assisted selection (MAS) technologies to accelerate African plant breeding efforts and deliver food security and economic growth. Over 100 African scientists established the network in 2003, with support from the Rockefeller Foundation.

The network brings regional and international agricultural researchers together, publishing information about its activities and providing contact information of all its members. It also links to news, scientific articles and other useful resources on MAS.

The AMMA programme aims to study how the West African monsoon affects meningitis and malaria epidemics. While it focuses on one weather system, the climate factors it looks at can be generalised to other environments. For example, it examines how wind, dust, rainfall, temperature and humidity, amongst others, affect mosquito density and malaria or meningitis epidemics in people. The website also offers a key resource for researchers in the form of an open-access bibliographic database containing more than 250 scientific articles.

AORTIC aims to improve cancer research, control and prevention in Africa. The organisation runs research projects on cervical cancer screening, hosts biannual conferences and publishes a monthly newsletter, in English and French, with news and commentary on cancer-related activities around Africa as well as a list of upcoming events. AORTIC's website offers links to other organisations working on cancer in Africa, lists training opportunities for scientists and health workers, and provides free access to relevant training manuals, scientific articles, books and presentations.

The African Scientific Network is a US-based organisation that aims to foster a bond between African scientists abroad (it has over 2000 members), and to facilitate collaboration with scientific activities in Africa. Its three main activities are the "African Scientific CD-ROM project", two "Physics in Africa Session", and the establishment of over 20 discipline-based groups and several alumni group.

The ATPS is a multidisciplinary network of researchers, policymakers and other stakeholders interested in generating, promoting and strengthening innovative technology and industrial policies in Africa. It provides small grants for research on science and technology policy in sub-Saharan countries and disseminates results through publications, workshops, conferences and the Internet. The network also organises training for policymakers, legislators, researchers and leaders in the private sector.

AfricanCrops.Net — funded by the Rockefeller Foundations Biotechnology, Breeding and Seed Systems Programme and the Partnership to Fight Striga of the African Agricultural Technology Foundation — publishes a monthly newsletter with information on upcoming conferences, training programmes and funding opportunities. It also hosts a discussion forum where visitors can share experiences of issues such as crop improvement and molecular marker applications.

The website links to a wide range of documents and points to resources dedicated to specific African crops such as cassava, cowpea and sorghum. It also hosts an extensive collection of links to online databases, glossaries, bibliographies, search engines, genetic maps and statistics relating to African-focused biotechnology and plant breeding research.
