a b s t r a c tRecent trends in abrupt weather changes continue to pose a challenge to agricultural production most especially in sub-Saharan Africa. The paper specifically addresses the questions on how local farmers read and predict the weather; and how they can collaborate with weather scientists in devising adaptation strategies for climate variability (CV) in the Okavango Delta of Botswana. Recent trends in agriculture-related weather variables available from country's climate services, as well as in freely available satellite rainfall products were analysed. The utility of a seasonal hydrological forecasting system for the study area in the context of supporting farmer's information needs were assessed. Through a multi-stage sampling procedure, a total of 592 households heads in 8 rural communities in the Okavango Delta were selected and interviewed using open and close-ended interview schedules. Also, 19 scientists were purposively selected and interviewed using questionnaires. Key informant interviews, focus group and knowledge validation workshops were used to generate qualitative information from both farmers and scientists. Descriptive and inferential statistics were used in summarising the data. Analysis of satellite rainfall products indicated that there was a consistent increase in total annual rainfall throughout the region in the last 10 years, accompanied by an increase in number of rain days, and reduction of duration of dry spells. However, there is a progressive increase in the region's temperatures leading to increase in potential evaporation. Findings from social surveys show that farmers' age, education level, number of years engaged in farming, sources of weather information, knowledge of weather forecasting and decision on farming practices either had a significant relationship or correlation with their perceptions about the nature of both local [ethno-meteorological] and scientific weather knowledge. Nonetheless, there was a significant difference in the mean scores of farmers in relation to their perceptions and those of the climate scientists about the nature of both local and Western knowledge. As farmers are adept at judging seasonal patterns through long-standing ethno-meteorology, one major CV adaptation measure is their ability to anticipate changes in future weather conditions, which enables them to adjust their farming calendars and make decisions on crop type selection in any given season.

Climate variability and change have adverse effects on agricultural production and other livelihood strategies of the rural households. The paper hypothesizes that rural households naturally devise means of overcoming the challenges currently posed by climate variability. The research article addresses the question of how rural households apply local knowledge of weather forecasting in adapting to climate variability in the Okavango Delta. It specifically probes, among others, the extent to which climate variability has affected agricultural production over the last 10 years in the area. A multistage sampling procedure was used to select a total of 592 households from eight rural communities. Key informant interviews, focus group discussions, and a stakeholder workshop were used to obtain demographic, socioeconomic, psychosocial, and climatic information. Households used both natural animate and inanimate indicators to predict the weather. To enhance household adaptation to climatic events, indigenous knowledge weather forecasters (ethnometeorologists) engaged in discussions with community members on their observation and interpretation of local weather conditions. Households devised adaptation strategies including the selection and preservation of drought-resistant, early maturing seeds, and shift in farming calendars to overcome the vagaries of weather patterns. Local and farming communities had a favorable perception about the accuracy of indigenous knowledge in weather forecasting (ethnometeorology) and therefore continue to utilize this knowledge system in weather forecasting. Most households perceived that change in weather patterns had a direct relationship with the decline in agricultural outputs over the last 10 years. Households’ experiential knowledge and ability to quantify their losses in farm yields as a result of climate-related problems provide an important insight for policy makers on how to address the impact of climate variability in the Okavango Delta, Botswana, and in similar social ecological contexts.

We carried out a study to determine ethno-veterinary knowledge used to treat and prevent livestock diseases in Toteng Village in Ngamiland District, northwestern Botswana. Primary data were collected through simple random sampling of 45 households in Toteng. Respondents were either livestock owners or cattle herders. Respondents were interviewed using a structured questionnaire which had both open and closed-ended questions. Cattle ownership or herdership in Toteng is an inter-generational occupation with people ranging from 15 to 94 years old. Cattle were acquired either through inheritance, buying, mafisa (reciprocal exchange) system or government scheme. Women in the study area were more involved in livestock farming activities. Eleven livestock diseases were reported to be prevalent in the study area. The top six diseases were tlhako le molomo -foot and mouth disease (FMD), matlho -eye infections, letshololo-diarrhea, madi -pasteurollosis, mokokomalo -aphosphorisis and pholoso-contagious abortion. At least nine medicinal plant species having ethno-veterinary applications were recorded in the study area. Single plants are mostly used rather than a combination of plants. A number of social strategies were mentioned such as 'go fetola mafudiso' -to change grazing areas, and 'go thaa lesaka' -to ritualistically 'protect a kraal' or livestock against evil spells and predators (lions). Although the intervention of conventional veterinary medicine is pervasive in Toteng, and many livestock owners are resorting to it, there is evidence, however, of generalized ethno-veterinary knowledge used to treat and prevent livestock diseases. Local farmers and their herders in Ngamiland are not only knowledgeable and experienced in treating a range of livestock diseases, but also in performing other veterinary tasks such as assisting in births, treating fractures and range management strategies to mitigate particular threats from their local environment. The efficacy of ethno-veterinary knowledge for preventing and treating livestock diseases and range management strategies identified in this study need to be fully investigated and integrated in veterinary extension services.
