ABSTRACT The aim of this study was to assess the utility of climate change and variability information for rice farming in Babati district of Manyara region.The subjects in this study were 122, comprising of 97 rice farmers, 07 key informants and 18 members of FGDs. Primary data were collected through questionnaire and checklist. Multiple responses analysis, chi-square test, linear and logistic regression were used to analyze the collected data. The result showed that 95.1% of the respondent...

Environmental degradation is a serious problem facing Nigeria’s environment. Until recently the major known causes of environmental pollution in the country include gas flaring, oil spillage, activities of artisanal miners, unsustainable exploitation of biological resources by the populace such as illegal logging, using of chemicals and explosives for fishing, emission of industrial effluents, poor waste management systems among others which are responsible for climate change, leading to gl...
ABSTRACT Declining soil fertility in general and nitrogen (N) in particular limit crop production on many smallholder farms in western Kenya. Soil N deficiency is usually ameliorated with inorganic N fertilizers but their high costs preclude their use by resource poor smallholder farmers. In addition there are concerns that increased use of inorganic fertilizers could lead to environmental degradation. Organic inputs offer sustainable alternatives to expensive inorganic N fertilizers but the ...
ABSTRACT An experiment to determine the effect of inorganic and organic fertilizers on the yield, fruit quality and soil fertility of Late Valencia (Citrus sinensi (L.) Osbeck) was carried out at the Forest and Horticultural Crops Research Centre, Kade in the semi-deciduous forest agro-ecological zone on a 13year old citrus orchard. The experiment was conducted in a randomized complete block design with four replications. The experiment consisted of six treatments: (I) 9 t/ha Oil palm empty f...
ABSTRACT The need to improve soil fertility and enhance crop production has led to a renewed interest in the use of cocoa pod husk (CPH) in form of biochar, an organic fertilizer, relative to, mineral fertilizer as soil amendment. The deleterious effect of inorganic fertilizer, on the environment, has been enumerated and the global effect of CPH. Field experiment on okra (Abelmoschus esculentus ) fertilized with Biochar. deried from cocoa pod husks (CPH), was conducted at the Cocoa Research I...
ABSTRACT The research on “The Forms and Effects of Soil Degradation on Agricultural Land” was calTied out in Bor town Jonglei State, south Sudan. The major areas of the investigation were discussed to known the causes of soil degradation and adverse impacts on farming land and what solutions to be put in place to minimize the occurrence of soil degradation. Methods like photography, interviews, questionnaires, and observation were used for effective and efficient data collection. At the p...
ABSTRACT Rapid urbanization has resulted into substantial increase in quantities of sewage, which is traditionally discharged into the ocean, causing a number of environmental problems including threats to oceanic lives as well as ground water contamination. So far, there is limited data in Kenya regarding the toxic effects of sewage on benthic organisms. The aim of this study was to investigate the biogeochemical effects of sewage pollution on the mollusc Nerita polita by determining its im...
Abstract This study assesses the sustainability of locally initiated community gardens as an adaptation strategy against climate change-induced food insecurity in Chikato ward 7 of Shurugwi district. Triangulation approach was employed in this study in which both qualitative and quantitative methods were used to collect data. Qualitative techniques included open-ended questionnaires, interviews, observations, focus group discussions and secondary data. Quantitative techniques comprised of clo...
ABSTRACT Generally, plastic is defined as long-chain organic material which can be formed into desired shape by the application of heat and pressure, also it extends to include so many organic metallic complexes and also certain long-chain inorganic material based principally on silicon, phosphorus, nitrogen, aluminum or boron or mixtures of these. It is still however true to say that the bulk of current commercial plastic are modified organic chemical, and that the inorganic polymers and th...
Abstract: The study evaluated the effects of soil organic matter amendments on temporal dynamics of populations of A. flavus and antagonistic microbes, and on aflatoxin contamination in groundnut under field conditions in Malawi. The study also investigated the implications of rainfall on populations of the microbes. Treatments included commercial organic fertilizer applied at the rates of 0.2, 0.4 and 0.6 t ha-1; and farmyard manure at rates of 2.5, 5.0 and 7.5 t ha-1, while an untreated pl...
ABSTRACT Food security is when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life. Foreign income generated from cocoa production serves as the backbone of the economy of Ghana, yet the high poverty prevalence amongst cocoa farming households affect greatly their food security status which in the long run leads to low production outputs. Therefore, this study seeks ...
ABSTRACT Studies have shown that poverty rates in Northern Ghana are two to three times more than the national average. Poverty, low income generation, and chronic food insecurity remains a critical challenge among the people in this region. Smallholder farmers in northern Ghana have limited access to the assets that would facilitate a shift from low productivity subsistence farming to modern commercial agriculture. The major constraints to their livelihoods include lack of infrastructure a...

The study analysed the economics of fish farming in selected local government areas of Taraba state, Nigeria. The specific objectives were to; (i) describe the socio-economic characteristics of fish farmers in the study area (ii), estimate the cost and returns of fish farming in the study area (iii), determine the relationship between input and output in fish farming in the study area; and (iv), identify the constraints faced by fish farmers in the study area. It utilized mainly primary data....
