Policy-making and programme formulation in regard to population, deforestation and other environmental problems in the humid tropics will have to be done in a context of uncertainty. Many facts are un...
Tropical deforestation accounts for almost one-fifth of greenhouse gas emissions and threatens the world’s most diverse ecosystems. Much of this deforestation is driven by illegal logging. We use nove...
Overcoming seasonality in the tropics by growing tomato (Lycopersicon esculentum Mill.) varieties under cooled conditions
Indeterminate Tomato Cherry Cooled Plastic House Off-Season Sudan Tropics
2013/2/28
The main objective of this work was to overcome seasonality in tomato production under hot tropical summer conditions, as well as to evaluate the adaptability and productivity of cherry and normal siz...
Asymmetric Variation in Soil Carbon Emission in Sub-Tropics
Soil Respiration Carbon Emission Bacterial Abundance
2013/2/26
Carbon dioxide emission from soil, known as soil respiration, is one of the major sources of the atmospheric carbon. Understanding the relationship between emission rate and the factors associated wit...
Long-term effects of management systems on crop yield and soil physical properties of semi-arid tropics of Vertisols
Broadbed and Furrow System Minimum Tillage Long-Term Experiment Sustainability
2013/3/5
Long-term experiments can be used to assess management induced changes in soil properties and sustainability of the management system in terms of the productivity. Such data are scanty, especially in ...
Factors Affecting High Mortality Rates of Dairy Replacement Calves and Heifers in the Tropics and Strategies for Their Reduction
Pre-weaning Calf Mortality Tropics Small Holder Dairy Systems
2016/5/9
The tropics is not an ideal location for calf rearing as the high temperatures and humidities introduce many potential disease problems to milk fed calves. In addition, the type of dairy farming (gene...
Effects of Cooling and Exogenous Bovine Somatotropin on Hematological and Biochemical Parameters at Different Stages of Lactation of Crossbred Holstein Friesian Cow in the Tropics
Cooling Recombinant Bovine Somatotropin Hematology Blood Chemistry Crossbred Holstein Freisian
2016/5/6
Effects of cooling and supplemental recombinant bovine somatotropin (rbST) on hemato-biochemical characteristics were studied at different stages of lactation of crossbred Holstein Friesian cows in a ...
Climatology and comparison of ozone from ENVISAT/GOMOS and SHADOZ/balloon-sonde observations in the southern tropics
ozone ENVISAT/GOMOS and SHADOZ/balloon-sonde observations the southern tropics
2010/9/1
In this paper, the stellar occultation instrument GOMOS is compared with ozonesondes from the SHADOZ network. We only used nighttime O3 profiles and selected 8 Southern Hemisphere stations. 7 years of...
First ground-based FTIR observations of methane in the inner tropics over several years
First ground-based FTIR observations methane the inner tropics
2010/8/16
Total column concentrations of methane have been retrieved from ground-based solar absorption FTIR spectra in the near-infrared recorded in Paramaribo (Suriname). The methane FTIR observations are com...
Co-located column and in situ measurements of CO2 in the tropics compared with model simulations
Co-located column in situ measurements the tropics model simulations
2010/8/13
The first ground-based remote sensing measurements of the column averaged volume mixing ratio of CO2 (XCO2) in tropical South America have been obtained at Paramaribo, Suriname (5.8° N, 55.2° W). The ...
More evidence for very short-lived substance contribution to stratospheric chlorine inferred from HCl balloon-borne in situ measurements in the tropics
short-lived substance contribution stratospheric chlorine HCl balloon-borne
2010/2/1
Volume mixing ratio (vmr) vertical profiles of hydrogen chloride (HCl) are retrieved from in situ measurements performed by a balloon-borne infrared tunable diode laser absorption spectrometer (SPIRAL...
Effect of Cultivation on Some Soil Attributes of a Long-term Pastoral Land in the Semiarid Tropics of Sudan
Management degradation grazing and soil properties
2010/11/15
Cultivation may have various effects on soil properties and could therefore be a useful guide
of soil quality indices. This study was conducted to determine the effects of more than 20 years cultivat...
Unified multifractal atmospheric dynamics tested in the tropics:part II,vertical scaling and generalized scale invariance
multifractal atmospheric dynamics vertical scaling generalized scale invariance
2009/11/16
We empirically investigate the scaling behaviour of the horizontal wind along the vertical direction using 287 radiosonde soundings with a resolution of 50 m. We compare the results obtained with thos...
Unified multifractal atmospheric dynamics tested in the tropics:part I,horizontal scaling and self criticality
multifractal atmospheric dynamics horizontal scaling self criticality
2009/11/16
In this paper we test the Unified Mulifractal model of atmospheric dynamics in the tropics. In the first part, we empirically investigate the scaling behaviour along the horizontal, in the second part...
Growth and Yield Response of Okra to Lime and Compost on an Acid Soil in the Humid Tropics
Abelmoschus esculentus acid soil compost Epe Ibadan lime
2010/11/15
Acid sands occur commonly in the high–rainfall areas along the coastal plains of Nigeria as
a serious constraint to crop production and a primary yield-limiting factor. Pot and field experiments were...
