Deficiency in the amino aldehyde dehydrogenase encoded by GmAMADH2, the homologue of rice Os2AP, enhances 2-acetyl-1-pyrroline biosynthesis in soybeans (Glycine max L.) por Arikit, Siwaret, Yoshihashi, Tadashi, Wanchana, Samart, Uyen, Tran T., Huong, Nguyen T. T., Wongpornchai, Sugunya, Vanavichit, Apichart

“…These results suggest that deficiency in the GmAMADH2 product, AMADH, plays a similar role in soybean as in rice, which is to promote 2AP biosynthesis. This phenomenon might be a conserved mechanism among plant species.…”

Cereal consumption and marketing responses by rural smallholders under rising cereal prices por Mottaleb, Khondoker Abdul, Rahut, Dil Bahadur

“…Combining this market phenomenon with Bangladesh Government’s Household Income and Expenditure Survey (HIES) data sets HIES 2005 and HIES 2010, and applying the seemingly unrelated regression (SUR) estimation process, the purpose of this paper is to examine paddy rice marketing, and the cereal and non-cereal food expenditure behavior of rural smallholders in Bangladesh under rising commodity prices.This study uses information collected by the Government of Bangladesh and applies two-step Heckman-type selection model estimation procedure, first to estimate total rice production by the rice production self-sufficiency status of the household. …”

El Niño-Southern Oscillation, rainfall, temperature and Normalized Difference Vegetation Index fluctuations in the Mara-Serengeti ecosystem por Ogutu, J., Piepho, Hans-Peter, Dublin, H.T., Bhola, N., Reid, Robin S.

“…The timings of droughts and floods coincided with strong episodes in the activities of the ENSO phenomenon. Above-average rainfall often accompanied cold ENSO episodes and below-average rainfall warm ENSO events, contrary to past generalizations suggesting that warm ENSO events are only associated with above-average rainfall whereas cold ENSO events with below-average rainfall in equatorial East Africa. …”

Knowing but not doing: selecting priority conservation areas and the research-implementation gap por Knight, A.T., Cowling, R.M., Rouget, M., Balmford, A., Lombard, A.T., Campbell, Bruce M.

“…This research-implementation gap between conservation science and real-world action is a genuine phenomenon and is a specific example of the “knowing-doing gap” that is widely recognized in management science. …”

Perspectives of predictive epidemiology and early warning systems for Rift Valley fever in Garissa, Kenya por Nanyingi, M.O., Muchemi, G.M., Kiama, S.G., Thumbi, Samuel M., Bett, Bernard K.

“…Climate variability is recognized as one of the major drivers contributing RVF epidemics and epizootics that have been closely linked to cyclic occurrence of the warm phase of the El Niño southern oscillation (ENSO) phenomenon. Using retrospective reanalysis and cross sectional participatory approaches we evaluate the impacts of climate change on pastoral communities and outline their roles in community based early warning systems for RVF. …”

The challenges and uses of quantitative economic modeling of agricultural policy decision process in Africa: a case study of South African land redistribution por Olubode-Awosola, O. O., Schalkwyk, H.D. van

“…There can be no doubt that such methods have important roles in illuminating policy effects thereby preventing policy mistakes. To exemplify this phenomenon, a forward-looking and prescriptive economic analysis that is being widely used in the developed world for agricultural policy analysis which supports the identification, prediction, prescription and comparison of alternative policy impacts was adopted to examine the potential effects of the South African land redistribution strategies on its agriculture with respect to equity and efficiency using an agricultural sector mathematical programming model. …”

Towards a viable system for monitoring agrobiodiversity on-farm: A proposed new approach for Red Listing of cultivated plant species por Padulosi, S., Dulloo, Mohammad Ehsan

“…Concerns for the loss of traditional crops seem to be increasing today among decision-makers, particularly in the context of climate change and the reduced adaptation and resilience of production systems with which this phenomenon is associated. In fact, from a livelihood perspective, loss of agrobiodiversity has a far greater impact, particularly on the poor, in terms of reduced options related to food security, income generation, environmental health and loss of many other intangible benefits. …”
