Difficulties in adaptation to climate change by oil palm farmers in Southern Nigeria
There is an increasing concern that climate change is already having an impact on poor, small scale oil palm farmers in Southern Nigeria. Researchers have shown that Nigeria is already being plagued with diverse ecological problems which have been linked to climate change. More so, increase in the severity of extreme weather events, sea level rise, coastal erosion, changes in weather pattern that affect oil palm...

Effects of moisture stresses during vegetative and reproductive growth phases on productivity of six selected rain-fed rice varieties in Ifakara, Tanzania
In order to study the critical growth stages and the most tolerant rice varieties in both lowland and upland rainfed ecosystems, an experiment arranged in split plots based on randomized complete block design was conducted under field conditions with 3 replications. Three stress timing irrigation treatments (no stress, vegetative moisture stress, and reproductive moisture stress) were assigned as th main plots, while 6...

Responses of Moringa oleifera root growth to container size during overwintering in temperate regions
Due to its fast growth rates, Moringa oleifera is being grown as an annual crop in temperate areas with freezing winter temperatures. Seedlings are raised under greenhouse conditions for overwintering and then transplanted outside at the beginning of spring, which allows for several cuttings prior to onset of the subsequent winter. However, there is limited information on container-size for overwintering of M. oleifera...

Assessment of technical conformity of bench terraces for soil erosion control in Rwanda
The purpose of this paper was to evaluate technical conformity of bench terraces in the Eastern Province of Rwanda. A sample of 180 actual bench terraces from 12 sites located in this Province was tested against technical standards and models provided for by the Ministry of Agriculture of Rwanda and Food and Agriculture Organization of the United Nations. The results showed that many sites have been constructed with no...

Levels of some selected metals (Fe, Cu and Zn) in selected vegetables and soil around eastern industry zone, central Ethiopia
The purpose of this study was to determine the concentration of selected metals (Fe, Zn and Cu) in vegetables and the soil contaminating levels due to irrigation, using Flame Atomic Absorption Spectrophotometer (FAAS). The wet digestion and sequential fractionation extraction procedures were employed to solubilize the metals from the collected samples. The results obtained from this study showed overall concentration of...

Levels of some toxic heavy metals (Cr, Cd and Pb) in selected vegetables and soil around eastern industry zone, central Ethiopia
The purpose of this study was to determine the concentration of heavy metals (Cr, Cd and Pb) in vegetables and the soil contaminating levels as a result of irrigation using Flame Atomic Absorption Spectrophotometer (FAAS). The wet digestion and sequential fractionation extraction procedures were employed to solubilize the metals from the collected samples. The results obtained from this study showed overall...

Land Use Land Cover Change Trend and Its Drivers in Somodo Watershed South Western, Ethiopia
Land use land cover (LULC) dynamics are a widespread, accelerating, and significant process driven by human actions. LULC changes analysis is one of the most precise techniques to understand how land was used in the past, what types of changes are to be expected in the future, as well as the forces and processes behind the changes. This study was carried out to evaluate the historical and future trends as well as...
