Communal farmers in most African countries have used both indigenous and modern knowledge to control ticks and tick-borne diseases. The aim of this paper is to report on the communal farmers' perceptions on the use of indigenous knowledge in controlling ticks and tick-borne diseases (Anaplasmosis) of cattle in the Katima Rural Constituency, Zambezi Region Namibia. The data was collected using structured questionnaires and analyzed as percentage of the participants. The results show that 85% of the participants are aware of the existence of ticks and tick-borne diseases affecting cattle in the study area and this suggests that the problems are evident in the area. It was also found that the roots, leaves and bark extracts of Muhonono (Terminalia sericia), Mukolotela (Piliostigmathonningii), Muchoko/Itanga (shrub) and Umbwiti/Ligwatanga (shrub) are often used by the farmers in the ethno-veterinary control of ticks and tick-borne diseases. This practice is evident among the older age bracket (51 – 70 years), with the 61 – 70 years old participants indicating complete reliance on the use of ethno-medicine to control their cattle's ticks and tick-borne diseases. Even though, there is an existing government policy that compels all farmers to vaccinate their animals against all sorts of livestock diseases in order to supply healthy meat to the markets, the financial cost of utilizing the conventional methods appears to be beyond the reach of most of the communal farmers. This effect will continue to promote the use of ethno-medicine in the control of ticks and tick-borne diseases in the study area. Therefore, there is need for government veterinary department to work with the communal farmers in identifying and standardizing the plant extracts for wider applications in controlling cattle's ticks and tick-borne diseases.

In Namibia, natural science (NS) is one of the priority subjects in upper primary phases (Grades 4 to 7). However, in the Omusati Region of Namibia, there are increasing public concerns that many learners are not performing well in NS. Thus, this study surveyed the views of NS teachers on the challenges affecting upper primary learners' performance in NS at three selected combined schools in the Omusati Region. Qualitative research design using face-to-face interview was used to gather the views of upper primary NS teachers in the schools. Seven teachers who are currently teaching NS at the selected schools were selected using the purposive sampling method to participate in the study. The results obtained revealed that the following challenges affect upper primary learners' performance in NS in the selected schools: medium of instruction, lack of adequate teaching and learning resources, lack of laboratories, sensitive topics, overcrowded classroom, indiscipline among learners, absenteeism, unfavorable teaching environment, hunger, and lack of proper guidance from subject advisory teachers. The study recommended that the government should provide schools with feeding programs, build laboratories, renovate classes and provide teaching materials. The schools should evolve disciplinary measures to check the learners' indiscipline.
