Abstract: Chimdi Lake has ecological significance as it has been a home for several associated biodiversities. A study was carried out to investigate the pollution status by analyzing some important physicochemical parameters of Chimdi Lake. The parameters analyzed were ambient temperature water temperature, Turbidity, Total Dissolved Solid (TDS), Total Suspended Solid (TSS), Conductivity, Hydrogen- ion-concentration (pH), Dissolved Oxygen (DO), Total hardness (TH), Chloride, Nitrate – Nitrogen (NO3-N), Phosphate- phosphorus (PO4-P), Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD) and fecal coliform. On the basis of pollution status found, the water of the lake was unfit for drinking purposes.

Abstract: The paper is a result of the study of the application of environmental accounting principles in boosting fish production in Nigeria. The neglect of the agricultural sector in the country has been a major set-back to the economic development. Therefore, a focus on boosting fish production will be apart from promoting the standard of living and economic health; through increased protein intake; lead to sustainable economic development. The objective of the paper was to evaluate how relevant environmental accounting principles will be applied in achieving this sustainable economic development. It was a survey of fish farmers from the 31 Local Government Areas of Akwa Ibom State to whom a questionnaire was administered to determine the level of applicability of Environmental Accounting principles. Also, secondary data for the period 2004 and 2013 were analyzed to identify economic potential and macroeconomic effects on increased fish production. It was discovered that there was a huge potential of investment and growth in the fisheries sub-sector as only 34% of annual demand was met by production. It was also discovered that the level of awareness and relevance of Environmental Accounting Principles was very low. It was recommended that government should focus on the fisheries sub- sector by providing the infrastructure and adequate training on fish farming and environmental matters to the farmers. Also, regulatory activities should focus on recycling of water, waste water treatment and proper drainage and soak- away pits to reduce the discharge of farm water into the environment. These done will boost fish production and ultimately reduce the strain on the foreign exchange reserve of the country.

Abstract: Evaluation of low cost drip irrigation technology was carried out under soil and agro climatic condition of Adami Tulu Agricultural Research Center, on-station so as to see its performance as compared to furrow irrigation systems for increased tomato productions. Four improved tomato verities were used for the purpose as test crop. The trials were replicated four times in a randomized block design. Some parameters of tomato and water use efficiency were used to compare the performance of the two irrigation systems. There was observed difference in some parameters of tomato under the two irrigation systems. Some tomato varieties perform well under drip while other performs well under furrow. But, the overall effect showed that drip irrigation system performed better than furrow irrigation system. Relatively higher mean yield of tomato was recorded under drip irrigation systems; 44.09 ton/ha for drip as compared to 43.38 ton/ha in surface irrigation. Drip irrigation used less water than that of surface irrigation systems, thus, giving much higher water use efficiencies. It was concluded that low cost drip systems achieved water saving of more than 25.9 as compared to surface irrigation systems. Finally this technology needs further evaluation under farmer circumstance for better finding.

Abstract: Economic valuation of microbial genetic resources was conducted in three Zones, Arsi from Oromia, East Shoa from Amhara and Wolhyta from Southern Nations Nationalities and People’s Region (SNNPR) of Ethiopia. Willingness to pay (WTP) bids to use Rhizobia bio-fertilizer for production of different legumes was calculated. The average willingness to pay for bio-fertilizer in haricot bean production was 201.76 USD (at existing exchange rate) /household/ year. When bio-fertilizer was used for faba bean production, increase by 1 hectare of land, increased the willingness to pay for bio-fertilizer by 667 USD/quintal/year. Moreover, Higher income is significantly related to higher WTP at (F=72.17, sig. = 0.000). In general the study showed that those farmers who have gained benefits from using Rhizobia biofertilizers in all the studied Sub-districts (kebels) indicated highest WTP for the bio-fertilizers in the study. There were certain factors like size of land holding, yield per hectare and herbicides that affected the total yield and thereby the WTP. Although there might be other factors that contributed for yield increases of the leguminous plants in the studied area, it may be possible to conclude that the benefit from the use of the bio-fertilizer was significantly higher compared to those gains obtained without using bio-fertilizers. Despite that there has been certain controversy on methodological issues involving willingness-to-pay, the support of WTP in determining the economic value of genetic resources widely increased. Thus the current economic value estimate of the rhizobia bacteria may be indicated by the WTP of the studied farmers.
