The study used the hypothetical lottery-choice questions to measure risk aversion and a detailed survey collected data on input use, farm production and non-farm activities to specifically assess whether risk aversion, risk perceptions, and socioeconomic factors affect the risk management strategies of farm households in Northern Ghana. Risk aversion significantly increases crop diversification strategies of households but marginally reduces herbicide use by households. Market risk significantly increases the use of improved seed varieties and the application of inorganic fertiliser but reduces diversification into livestock production. Production risk largely increases diversification into livestock production. Farmers’ risk management strategies are affected by socioeconomic variables such as access to extension services, area cultivated, age and gender. Policy effort focused on building pliable on-farm crop related risk management strategies should aim at considering the risk aversion and the perception of market risk whilst those focused on livestock should focus on production risk. 相似文献

The current share of sub-Saharan Africa in global carbon dioxide emissions is negligible compared to major contributors like Asia, Americas, and Europe. This trend is, however, likely to change given that both economic growth and rate of urbanization in the region are projected to be robust in the future. The current study contributes to the literature by examining both the direct and the indirect impacts of quality of institution on the environment. Specifically, we investigate whether the institutional setting in the region provides some sort of a complementary role in the environment-FEG relationships. We use the panel two-step system generalized method of moments (GMM) technique to deal with the simultaneity problem. Data consists of 43 sub-Saharan African countries. The result shows that energy inefficiency compromises environmental standards. However, the quality of the institutional setting helps moderate this negative consequences; countries with good institutions show greater prospects than countries with poor institutions. On the other hand, globalization of the region and increased forest size generate positive environmental outcomes in the region. Their impacts are, however, independent of the quality of institution. Afforestation programs, promotion of other clean energy types, and investment in energy efficiency, basic city infrastructure, and regulatory and institutional structures, are desirable policies to pursue to safeguard the environment. 相似文献

A number of pesticide residues in fruits were monitored at five markets in the Accra Metropolis for almost a year. Locally produced fruits (pawpaw and tomato) and imported apple were purchased from these selected markets in the metropolis and analyzed for pesticide residues by gas chromatography equipped with electron capture detector. In all, 320 sampled fruits were extracted and analyzed for pesticide residues, mainly organochlorines (??-HCH, ??-HCH, aldrin, heptachlor, ??-chlordane, heptachlor epoxide, ??-endosulfan, p,p??-DDE, endrin, ??-endosulfan, o,p??-DDT, endrin aldehyde, p,p??- DDT, endrin ketone, and methoxychlor). The data revealed that 32.8% of the fruit samples analyzed contained residues of the monitored insecticides above the accepted maximum residue limit (MRL) whereas 48.7% were below the MRL. Nonetheless, the continuous consumption of such fruits with modest pesticide levels can accumulate and could result in deadly chronic effects. 相似文献

Biodegradable packaging has high potential to help solve the crisis of non-biodegradable plastic waste causing an increase in the footprint of landfills. However, more research needs to be executed to develop a larger assortment of biodegradable plastics for numerous applications and to make them more economical to manufacture. This paper discusses the design and validation of an automated composting system (AMUCS) that fits the requirements of the American Society for Testing and Materials (ASTM) 5338-11 standard. The results of the experiments show that the AMUCS was able to create and maintain the conditions for biodegradation of biodegradable polymers in compost using microcrystalline cellulose. The biodegradation caused by the composting environment was observed visually with the naked eye and on the micro scale with an environmental scanning electron microscope. The magnitude of biodegradation was measured by calculating the carbon metabolized from the samples. The carbon metabolized from the three compost replicates was consistent and linear, and there was only an 8 % difference between the non-biodegradable low density polyethylene and the compost. For the biodegradation study according to ASTM D 5338-11, the experiment was validated with the use of cellulose as a reference material. Under controlled composting conditions, the mineralization of microcrystalline cellulose yielded 72.05 %, which is slightly higher than the 70 % mineralization requirement. 相似文献

As part of the Ghanaian government's efforts to revive the national economy a series of measures were instituted. They included devaluation of the local currency, reduction of budget deficits and the rehabilitation of basic infrastructure. The mining industry plays an important role in the national economy and special measures were also introduced to encourage its rehabilitation and development. A new licensing system was introduced and a new fiscal regime was established which inter alia allows mining companies to retain part of their export earnings offshore. The response of the private investment community to those changes has been excellent and investment in the mining industry has increased substantially. 相似文献
