16 pages, Background
An estimated 140 million people in Africa face acute malnutrition. By impacting agricultural production, climate change is likely to further decrease food consumption, particularly in sub-Saharan African states. Against this backdrop, various actors have called for more attention to alternative farming and food systems based on traditional agricultural knowledge capable of ensuring access to sufficient, nutritious, and safe food. So far, however, we have limited systematic evidence on which traditional agricultural practices may promote the food resilience of households exposed to extreme climatic conditions. Focusing on the most prevalent traditional diversification practices in Tanzania, this study assesses the extent to which crop diversification, annual crop intercropping, crop-tree intercropping, crop-livestock integration, and the cultivation of traditional crops increase the food availability and dietary diversity of smallholders facing extreme weather events in Tanzania.
Methods
We combine temperature and rain data with information on farming practices and food consumption information provided by the Living Standards Measurement Study–Integrated Surveys on Agriculture for more than 25,000 Tanzanian households nationwide. We rely on a matched differences-in-differences approach to account for selection bias and allow for causal inference.
Results
Our matching models consistently show that the planting of traditional crops (in particular sorghum) promotes dietary diversity and reduces the need for food rationing in households experiencing climate shocks. In contrast, households relying on maize cultivation show less dietary diversity and increased food rationing behavior. In addition, we find that—under extreme weather conditions—crop diversification furthers households’ dietary diversity, and crop-livestock integration, as well as crop-tree intercropping, seem to reduce households’ need to ration food.
Conclusion and policy recommendation
This study has important implications for policymakers. In light of climate change and weather variability, it underscores the need to better integrate indigenous knowledge into farming systems. Our results call for greater dissemination of traditional diversification strategies and more reliance on indigenous, drought-tolerant crops. Traditional farming practices can function as a safety net, protecting smallholders in Tanzania against the detrimental consequences of weather shocks.
15 pages, Agriculture is a significant contributor to the global economy and critical for future food and fibre production. To maximise the industry efficiencies and improve sustainability, a knowledgeable workforce is essential. Today’s school-aged youth will be the next generation agriculture workforce. However, there is concern that today’s youth are more detached from agriculture than ever before, viewing the industry as an unattractive career prospect and possessing low levels of agricultural literacy. Using a qualitative approach, this research presents the results from an open-response survey item asking Australian primary and secondary students to ‘list three words you think of when you hear the word ‘agriculture’’. Focus groups with Australian primary and secondary teachers were also conducted to explore these findings. Overall, students appear to have what can be described as a conventional understanding of agriculture as it relates to traditional farming, particularly animal production. However, students appeared to have a lower level of understanding and perception of the industry in less-traditional settings, including modern careers and the technologies involved. Improved agricultural education in Australia, including both formal and informal programs on possible career paths and technology adoption in the industry is recommended to support knowledge development of the modern sector to attract the next generation workforce.
8 pages, Agricultural extension is now backing on the development agenda. The acknowledged failure of the traditional extension model in India has stimulated debate on extension reforms and the introduction of new extension models. Further, Indian agriculture has recorded an alarming ‘knowledge gap’ where ‘knowledge’ became central to agricultural production. The role of extension functionaries today is more challenging and demands structural and functional changes to meet the holistic needs of farmers and they have to equip themselves to cope with the drastic chance and dire needs. Agricultural extension is not only about imparting knowledge and securing adoption of improved practices but it also aims at changing the outlook of farmers. Moreover, Indian agriculture is undergoing a rapid transformation under globalization from a simple making a living to complex endeavour. Information revolution leads to fundamental changes in economic, political, social and cultural relations. Information technology is the lifeblood of many other technologies. It is opined that there is direct relationship between communication and development of agricultural sector. New information technology provides the opportunity for innovation. The ‘free flow of information’ will help the farmers is to overcome the knowledge gap and the availability of the new technology lead farmers to make real choice. This paper emphasizes on the role of ICTs in contemporary agricultural context and critically understands the failure of traditional extension functionaries.
9pgs, Soil loss due to crop harvest contributes to land degradation, and knowledge of this challenge can guide the choice of crops for sustainable agriculture. Nigeria is the largest producer of cassava (Manihot esculenta Crantz) and the third largest producer of peanut (Arachis hypogaea Linn) in the world. Due to limited information on soil loss during peanut and cassava harvests worldwide, and cost of nutrient loss, a two-year field experiment was conducted to compare soil loss due to harvesting of peanut and cassava and to estimate cost of nutrient loss due to crop harvest under traditional agriculture. Peanut pod yields of 2.39 and 2.08 t ha–1harvest–1 removed 0.62 and 0.58 t ha–1 harvest–1 during peanut harvest, respectively, for years 1 and 2. Similarly, cassava yields of 22.71 and 21.40 t ha–1 harvest–1 removed 1.11 and 0.91 t ha–1harvest–1 during cassava harvest, respectively, for years 1 and 2. Crop yields strongly correlated with soil loss due to peanut harvest (R2= 0.36; p < 0.001) and soil loss due to cassava harvest (R2 = 0.23; p < 0.01). Significantly higher soil loss due to cassava harvest compared to peanut harvest can be ascribed to higher cassava yield. Also, soil nutrient loss due to crop harvest was significantly (p < 0.001) higher for cassava compared with peanut by 27.6% phosphorus (P) and 73.7% potassium (K) for the first year and 39.2% P and 79.1% K for the second year. Fertilizer equivalent cost of P and K losses due to cassava harvest for the two years was higher than that of peanut by US$29 ha–1. The study indicated that the intensity of nutrient loss by harvesting is largely dependent on the crop type, and harvesting of cassava can deplete soil nutrients faster than that of peanut under traditional agriculture. Sequential planting of cassava (deep rooted crop) followed by peanut (shallow rooted crop) as a crop rotation management practice is recommended to mitigate soil loss due to continuous harvesting of cassava, and harvesting with thorough shaking technique is also suggested to reduce nutrient loss potential of crop harvesting.
