“…In Madagascar, an equal range of between 25% and 50% increase in yields and decrease in water use were reported [16]. A similar trend has been reported in China where both increase in yield and decrease in water use were found to be up to 46% [17]. In those regards, SRI has more advantages than the conventional approaches in subsistence farmer setup.…”

The demand of water for irrigation purposes in Tanzania outstrips the amount of water available for irrigation and other demands. On the other hand, the demand for more food to feed the growing population is increasing, calling for the need to have technologies and farming practices that ensure more food production while minimizing water uses. Rice is among cereal crops grown in Tanzania, and it can assist in meeting the food demand for the nation. Majority of rice producers in Tanzania and Sub-Saharan Africa (SSA) are subsistence farmers and they practice continuous flooding, a technique that requires much water. In addition to using large amounts of water, the conventional practices of growing paddy using local varieties transplanting process are implemented when seedlings are more than 21 days old, and 3 -4 seedlings are transplanted in one hole. This practice results in low yields, and low water productivity and water use efficiency. The system of rice intensification (SRI) on the other hand, is a promising new practice of growing paddy rice that has proven to be very effective in saving water and increasing rice yields in many parts of the world. SRI practice is spreading fast and it has been adopted in many countries. The SRI practice has been introduced in Tanzania during the last 3 years as such it is not widely practiced. This paper reviews SRI practice at global, regional and country (Tanzania) level, and evaluates the challenges, opportunities and implications for its adoption in Tanzania. Knowledge gaps at each level have been identified and discussed as well as suggestions for researchable areas.

“…Conflicting results exist, some reporting that a 20% -40% increase in yield and up to 50% water savings [16,[19][20][21]; while others reported insignificant gains [22]. The variation is likely to be attributed to subjective referencing system.…”

“…Moreover, especially in Africa, many available technologies are not, or only slowly, adopted, which may be due to unsuitable technological characteristics or unfavorable framework conditions (Barrett et al, 2004;Smale and Tushemereirwe, 2007). Rigorous adoption and impact studies are required to better understand what type of technologies work under what conditions.…”

“…For example, resistance build-up in pest populations or growing importance of secondary pests may potentially lower Bt benefits over time (22)(23)(24). Second, most impact studies do not properly control for nonrandom selection bias (17), which may occur when more successful farmers adopt the new technology earlier or more widely (25). As these successful farmers may have higher crop yields and profits anyway, this can result in inflated benefit estimates.…”

Despite widespread adoption of genetically modified crops in many countries, heated controversies about their advantages and disadvantages continue. Especially for developing countries, there are concerns that genetically modified crops fail to benefit smallholder farmers and contribute to social and economic hardship. Many economic studies contradict this view, but most of them look at short-term impacts only, so that uncertainty about longer-term effects prevails. We address this shortcoming by analyzing economic impacts and impact dynamics of Bt cotton in India. Building on unique panel data collected between 2002 and 2008, and controlling for nonrandom selection bias in technology adoption, we show that Bt has caused a 24% increase in cotton yield per acre through reduced pest damage and a 50% gain in cotton profit among smallholders. These benefits are stable; there are even indications that they have increased over time. We further show that Bt cotton adoption has raised consumption expenditures, a common measure of household living standard, by 18% during the 2006–2008 period. We conclude that Bt cotton has created large and sustainable benefits, which contribute to positive economic and social development in India.
