Botswana College of Agriculture is an agricultural college located in Gaborone, Botswana. It was established by an act of the Parliament of Botswana, Act no. 9, on 31 May 1991. The Act abolished the then Botswana Agricultural College which had existed since 1967.The College is a parastatal under the Ministry of Agriculture and an associate Institution of the University of Botswana. As an associate institution the College offers UB higher diploma and degree programmes in agricultural science, while its responsible on its own for short courses offered by its Centre for In-service and Continuing Education .

Safflower (Carthamus tintorius L.) belongs to the family Compositae or Asteracea. It's a multipurpose oilseed crop grown mainly for its high quality edible oil and bird seed. Initially safflower oil was used as a source of oil for the paint industry, now its edible oil is used for cooking, making margarine and salad oil. Safflower is also grown for its flowers which are used as cut flowers, colouring and flavouring foods, making dyes for the textile industry, livestock forage, vegetable, making herbal teas and medicinal purposes. In China safflower is grown as a medicinal plant for the treatment of cardiovascular diseases, male and female sterility, lowering blood cholesterol, release of retained placenta and still birth, induction of labour in expectant women, delayed, heavy and painful menstrual periods, various types of rheumatism (sciatica, thorax, arthritis), respiratory diseases (whooping cough, chronic bronchitis), gastritis, etc. Despite the many uses of safflower, it has remained a minor crop. Therefore, it is essential for the scientific community to carry out research on this crop and popularize it as a commercial crop for development of pharmaceuticals, edible oil, paint and varnishes industry, dye extraction (carthamin), source of a-tocopherol, livestock feed, vegetable and cut flower. © 2010 Asian Network for Scientific Information.

Rain-fed agriculture constitutes the livelihood base for the vast majority of rural inhabitants in developing countries as a source of food security, employment and cash income. Nevertheless, rain-fed agriculture is extremely vulnerable to climate variability and droughts. Changes in rainfall patterns and droughts increase the likelihood of short-run crop failures and long-run production declines causing food insecurity. For commodity-based economies, this shortfall is normally met through imports financed by revenues from mineral exports. However, the 2008 global recession that saw commodity prices plummeting and at the same time food price increasing exacerbated the food insecurity in these countries. The impending recession due to Euro crisis is likely to be a death blow. This article explores the climatic limitations to rain-fed agriculture and the confounding effects of global recession on food security in Botswana. The analysis identifies rainfall spatial variability and its relationship to yield instability. While food price increases and the financial meltdown co-acted to amplify the already dire climate-induced food insecurity in the country. This article discusses policies that the government could adopt to help its farmers adapt to climate variability and also to future financial perturbations that are likely to constrain food security. © 2012 Copyright Taylor and Francis Group, LLC.

The objective of this study was to analyze land use/land cover (LULC) changes in the landscape of Munessa-Shashemene area of the Ethiopian highlands over a period of 39 years (1973-2012). Satellite images of Landsat MSS (1973), TM (1986), ETM+ (2000), and RapidEye (2012) were used. All images were classified using object-based image classification technique. Accuracy assessments were conducted for each reference year. Change analysis was carried out using post classification comparison in GIS. Nine LULCs were successfully captured with overall accuracies ranging from 85.7% to 93.2% and Kappa statistic of 0.822 to 0.924. The classification result revealed that grasslands (42.3%), natural forests (21%), and woodlands (11.4%) were dominant LULC types in 1973. In 2012, croplands (48.5%) were the major LULC types followed by others. The change result shows that a rapid reduction in woodland cover of 81.8%, 52.3%, and 36.1% occurred between the first (1973-1986), second (1986-2000), and third (2000-2012) study periods, respectively. Similarly, natural forests cover decreased by 26.1% during the first, 21.1% during the second, and 24.4% during the third periods. Grasslands also declined by 11.9, 17.5, and 21.1% during the three periods, respectively. On the contrary, croplands increased in all three periods by 131, 31.5, and 22.7%, respectively. Analysis of the 39-year change matrix revealed that about 60% of the land showed changes in LULC. Changes were also common along the slope gradient and agro-ecological zones with varying proportions. Further study is suggested to investigate detailed drivers and consequences of changes. © 2013 by the authors. Source

Samples of sorghum grain and malt, traditional opaque sweet beverage (thobwa) and beer prepared from sorghum malts, were collected from the southern region of Malawi during the humid month of January. The samples were analyzed for total aflatoxins using aflatest VICAM fluorometry procedure. All malt and beer samples, 15% and 43% of the sorghum and thobwa samples, respectively, were contaminated with aflatoxins. The sorghum malt prepared for beer brewing, had a significantly (p < 0.01) higher total aflatoxin content (average 408 ± 68 μg/kg [SEM]) than any other type of sample. The average aflatoxin content in the beer was 22.32 μg/l, which is higher than the permissible maximum level in ready to eat foods set by Codex Alimentarius Commission (10 μg/kg). Thus consumption of opaque sorghum-based traditional beer poses a risk of aflatoxin exposure. © 2010 Elsevier Ltd. Source

Poultry meat (mainly chicken) production in Botswana has experienced phenomenal growth over time (i.e., 1982 to 2010). This growth is attributable to inter alia government assistance such as Financial Assistance Policy (FAP) and restrictions on imports in accordance with Control of Goods Act. The country's demand for poultry meat is estimated to be 60 000 tonnes. The growth of the poultry meat industry calls for adoption of high hygiene standards by the processing plants to ensure wholesomeness of the products. However, the growth of the industry has been hampered by frequent disease outbreaks and inadequate extension service. Currently, only 28 poultry abattoirs are licensed with the Department of Veterinary Service and thus receive technical support from government meat inspectors. This implies that the hygiene in the unregistered abattoirs is inadequate indicating that food safety has been neglected for a long time. Opportunities exist in further processing of poultry meat into various products. Source
