Simple power-law models to predict flow metrics for water resource and risk management along the Mekong tributaries. [Abstract only] por Lacombe, Guillaume, Douangsavanh, Somphasith, Vogel, R., McCartney, Matthew P., Chemin, Yann H., Rebelo, Lisa-Maria, Sotoukee, Touleelor

“…The most integrated and informative way to characterize flow, at a specific location on a river, is to compute a flow duration curve which provides the percentage of time (duration) any particular flow is exceeded over a historical period. Using hydro-meteorological records from more than 60 gauged catchments in the Lower Mekong Basin, and a 90-meter digital elevation model, we used multiple linear regressions to develop power-law models predicting flow duration curves. …”

An expert system model for mapping tropical wetlands and peatlands reveals South America as the largest contributor por Gumbricht, Thomas, Román Cuesta, Rosa María, Verchot, Louis V., Herold, Martin, Wittmann, Florian, Householder, Ethan, Herold, Nadine, Murdiyarso, Daniel

“…We present an expert system approach to estimate wetland and peatland areas, depths and volumes, which relies on three biophysical indices related to wetland and peat formation: (1) long-term water supply exceeding atmospheric water demand; (2) annually or seasonally water-logged soils; and (3) a geomorphological position where water is supplied and retained. …”

Application of secondary nutrients and micronutrients increases crop yields in sub-Saharan Africa por Kihara, Job Maguta, Sileshi, Gudeta W., Nziguheba, Generose, Kinyua, Michael, Zingore, Shamie, Sommer, Rolf

“…The major points are the following: (1) application of S and micronutrients increased maize yield by 0.84 t ha−1 (i.e., 25%) over macronutrient only treatment and achieved agronomic efficiencies (kilograms of grain increase per kilogram of micronutrient added) between 38 and 432 and (2) response ratios were >1 for S and all micronutrients, i.e., the probability of response ratio exceeding 1 was 0.77 for S and 0.83 for Zn, 0.95 for Cu, and 0.92 for Fe, and indicates positive crop response for a majority of farmers. …”

Comparing FAMACHA© eye colour chart and haemoglobin colour scale tests for detecting anaemia and improving treatment of bovine trypanosomosis in West Africa por Grace, Delia, Himstedt, H., Sidibe, I., Randolph, Thomas F., Clausen, Peter-Henning

“…African animal trypanosomosis (AAT) is considered the most important cattle disease in sub-Saharan Africa but its diagnosis in the field is difficult, resulting in inappropriate treatments, excessive delay in treatments and under-treatment. …”

Response of grain legumes to phosphorus application in the guinea savanna agro-ecological zones of Ghana por Adjei-Nsiah, Samuel, Alabi, B.U., Ahiakpa, J.K., Kanampiu, F.K.

“…However, yields are low, rarely exceeding 600 kg ha−1, prompting the need to evaluate responses of grain legumes to P fertilizer applications for two seasons. …”

Uncovering the economic value of natural enemies and true costs of chemical insecticides to cotton farmers in China por Huang, Jikun, Zhou, Ke, Zhang, Wei, Deng, Xiangzheng, Werf, Wopke van der, Lu, Yanhui, Wu, Kongming, Rosegrant, Mark W.

“…The use of broad-spectrum insecticides by farmers is alarmingly excessive, not only undermining farmers' profitability but also inducing social costs as well as disruption of the natural pest suppression system. …”

Assessing the economic impact of vaccine availability when controlling foot and mouth disease outbreaks por Porphyre, T., Rich, Karl M., Auty, H.K.

“…The probability of direct costs exceeding £500 million is reduced when vaccination is used and is steadily reduced further as the size of initial vaccine stock increases. …”

Septoria Leaf Spot Reduces Flower Bud Set and Yield Potential of Rabbiteye and Southern Highbush Blueberries por Ojiambo, P.S., Scherm, H., Brannen, P.M.

“…On Premier, yield potential dropped markedly and significantly as disease severity the previous fall exceeded about 50 to 60 spots per leaf on average (P < 0.0001 based on a Kruskal-Wallis test). …”

Long-term effects of row orientation on oil yield and oil yield components of hedgerow olive orchards cv. Arbequina por Gómez del Campo, María, Trentacoste, Eduardo Rafael, Connor, David J.

“…Oil yield was highly variable from year to year in a range 1.7–3.6 t oil/ha but average yield of NE–SW, although not different from NW–SE and N–S, was significantly greater than E–W by 12%. Yield of NE–SW exceeded those of other orientations in two of the seven years of observation by increase in fruit number without effect on fruit size or oil concentration. …”

Soil saturated hydraulic conductivity assessment from expert evaluation of field characteristics using an ordered logistic regression model por Ingelmo, Florencio, Molina, María J., De-Paz, José M., Visconti, Fernando

“…Moreover, wrong estimation of the Ks class exceeded the ±1 range only in 3% of sites. Therefore, a reliable enough assessment of Ks can be based on the expert assessment of field characteristics in combination with an OLRM. …”

Economic injury levels for Asian citrus psyllid control in process oranges from mature trees with high incidence of huanglongbing por Monzó, César, Stansly, Philip A.

“…A conservative threshold for mature trees with high incidence of HLB would help maintain economic viability by reducing excessive insecticide sprays, thereby leaving more room for non-aggressive management tools such as biological control.…”
