IMPLICATIONS OF THE WORLD FOOD CRISES ON TRENDS OF LOCAL FOOD PRICES IN THE UPPER EAST REGION OF GHANA AgEcon
Akudugu, M.A..
The global food crisis led to upward trends in food prices across the world. The millions of impoverished people living in developing countries including Ghana were the worst affected by the phenomenal increases in world food prices. This paper examines the implications of the global food crisis on the trends of food prices in the Upper East Region of Ghana. The data used for the analyses were average monthly prices of some selected grain cereals, grain legumes, vegetables, and root and tuber food items consumed in the region. The data were gathered from the Upper East Regional Directorate of the Ministry of Food and Agriculture. The analyses revealed that on the average, the prices of food items grew over 200 percent during the last twenty years. However,...

A General Equilibrium Analysis of the Impact of Inward FDI on Ghana: The Role of Complementary Policies AgEcon
Arbenser, Lawrence.
The need for external capital (FDI) inflow to finance the current account deficit of developing countries cannot be over-emphasized. Foreign direct investment takes predominance over other types of capital inflow into developing countries. How would an increase in FDI and a reduction in import tariff levels in isolation affect household welfare and other macroeconomic indicators? How would the concurrent application of the two enhance the expected impact? This paper explores the above questions by using a Computable General Equilibrium (CGE) model for Ghana, implemented in the General Algebraic Modeling System (GAMS) to carry out specific counterfactual simulations. This paper concludes that the primary benefit of an increase in FDI inflow for a...

Responding to Economic Shocks in Ghana: The Agricultural Sector as a Social Safety Net AgEcon
Sarpong, Daniel Bruce; Asuming-Brempong, Samuel.
The objective of this paper is to document, assess and characterize the role Ghana's agriculture has played as a safety net when the urban labor market suffered economic shocks. The study explores how agriculture influences non-agricultural dependent households. Specific attention is given to the implicit value of the informal insurance role that rural households play in supporting family members who lose jobs acquired after migrating to urban areas. The paper analyses Ghanaian agriculture's social security role in the late 1980s and 1990s. This well documented period in Ghanaian economic literature, coincides with both natural and macro policy shocks and the policy measures taken to cope with the shocks.

Smallholder Adoption of Soil and Water Conservation Practices in Northern Ghana AgEcon
Nkegbe, Paul K.; Shankar, Bhavani; Ceddia, M. Graziano.
Both governmental and non-governmental organizations are engaged in the promotion of soil and water conservation practices in northern Ghana, but adoption is believed to be low. This study thus examines the determinants of conservation practices by farming households in the area. Data for the study was collected from 445 households located in 15 communities in northern Ghana. Univariate, bivariate and multivariate probit models were used to analyse the decision to adopt six conservation practices in the area. Results show the major determinants of adoption are plot and cropping characteristics such as location; and socio-economic and institutional variables such as number of contacts with extension officers, membership in farmer association and distance to...

Did farmers’ livelihood improve? An impact assessment of incorporating forages into the crop-livestock system in the coastal savannah zone of Ghana AgEcon
Ameleke, G.Y.; Okantah, S.A.; Sottie, E.T.; Marfo-Ahenkora, E.A.; Aboe, P.A.T..
The study used programming methods to assess the farm-level impact of incorporating forages, including dual purpose Cajanus cajan (C. cajan), into the crop-livestock system in the Coastal Savannah Zone of Ghana. The system was modeled in GAMS and solved using linear programming. The optimal enterprise mixes and their resultant net revenues with and without the interventions and therefore the change in net revenue were obtained. The intervention was to grow forages as part of the crop-livestock system and feed them to milking cows and their calves for increased milk production and growth. The grain of the forage was used as food by the farmers, and manure from the animals was also used for crop production. The effect of policy options like educating farmers...

Border Effects on Spatial Price Transmission between Fresh Tomato Markets in Ghana and Burkina-Faso: Any Case for Promoting Trans-border Trade in West Africa? AgEcon
Amikuzuno, Joseph.
Cross-border trade in food commodities within sub-regional economic blocks in Sub-Sahara Africa (SSA) is believed to be faster, cheaper, more convenient and welfare-enhancing than trade between SSA countries and the USA or EU. The difficulty of commodity arbitrage across borders in SSA is however a fundamental impediment to price transmission, market integration and the realisation of the welfare-enhancing role of cross-border trade. This study examines the impact of border and distance on price transmission between tomato in Ghana and Burkina-Faso. The analysis applies a linear and a regime-switching vector error correction model to estimate wholesale prices of tomato in four tomato markets in Ghana and a producer market in Burkina-Faso. The estimated...

Grain price adjustment asymmetry: the case of cowpea in Ghana AgEcon
Langyintuo, Augustine S..
Patterns in price adjustment in response to information are important to market practitioners. This study looks at cowpea real wholesale price adjustment patterns in Bolgatanga, Wa, Makola and Techiman markets in Ghana. Using Techiman as the central market, a threshold autoregressive test for asymmetric price adjustment rejected the null hypothesis of symmetric adjustment for only the Bolgatanga-Techiman price series. An autoregressive conditional heteroskedastic regression indicates that wholesalers in Bolgatanga market respond differentially to price signals from Techiman than those in the other two markets. This suggests that policies targeting cowpea traders must recognize the differential responses by wholesalers to information.

Vegetable Production and Pesticide Use in Ghana: Would GM Varieties Have an Impact at the Farm Level? AgEcon
Horna, J. Daniela; Timpo, Samuel E.; Al-Hassan, Ramatu M.; Smale, Melinda; Falck-Zepeda, Jose Benjamin.
The objective of this study is to evaluate pesticide use as an important factor affecting potential adoption and farm level impact of genetically modified (GM) vegetable varieties in Ghana. Tomato is the most consumed vegetable and a food security crop. Cabbage is a vegetable of growing importance but limited cultivation and is produced in urban areas. Garden egg is a native African crop of wide consumption and importance for rural economies. Farm level information was collected in randomly selected sites in southern and central regions of Ghana. Partial budget analysis shows that investments in pesticides are rather low, especially for tomato and garden egg. Analysis of production using an abatement framework shows that insecticide amounts are significant...

Public expenditures and agricultural productivity growth in Ghana AgEcon
Benin, Samuel; Mogues, Tewodaj; Cudjoe, Godsway; Randriamamonjy, Josee.
Using district- and regional-level public expenditure data and household-level production data, this paper estimates the agricultural productivity returns to different types of public expenditure across various agro-ecological zones of Ghana. The results reveal that provision of various public goods and services in the agricultural, education, health and rural roads sectors have substantial impact on agricultural productivity. A one percent increase in public spending on agriculture is associated with a 0.15 percent increase in agricultural labor productivity, with a benefit-cost ratio of 16.8. Spending on feeder roads ranks second (with a benefit-cost ratio of 5), followed by health (about one hundredth of the value). Formal education was negatively...

District-level Spatial Analysis of Migration Flows in Ghana: Determinants and Implications for Policy AgEcon
Tsegai, Daniel W.; Le, Quang Bao.
The present study investigates the determinants of inter-district migration flows over the 1995-2000 period in Ghana. A combination of socio-economic, natural and spatial ‘district-level’ attributes are considered as potential variables explaining the direction of migration flows. In addition to the ‘net’ migration model, ‘in’ and ‘out’ migration models are also employed within the context of the gravity model. Results in the three models consistently show that people move out of districts with less employment and choose districts with high employment rate as destinations. While shorter distance to roads encourages out-migration, districts with better water access seem to attract migrants. Generally, people move out of predominantly agrarian districts to...

Tracing Power and Influence in Networks: Net-Map as a Tool for Research and Strategic Network Planning AgEcon
Schiffer, Eva; Waale, Douglas.
Believing that complex problems call for complex solutions and that stakeholders should have a say in policies that concern them, policymakers have strongly promoted the development of forums and organizations made up of many stakeholders to address complex governance issues such as water management. Both developing and developed countries have instituted multistakeholder water governance bodies on local, national, and international levels. However, while the belief is strong that these integrated bodies should improve governance, how and to what extent that actually happens is still unclear, not only because of the complexity of the matter but also due to a lack of appropriate research tools for the analysis of complex governance systems. This paper...

Serological Detection of Newcastle Disease Virus Antibodies in Local Chickens and Guinea Fowls in the Area of Kumasi, Ghana Rev. Bras. Ciênc. Avic.
Boakye,OD; Emikpe,BO; Folitse,RD; Bonnah,SG; Adusei,K; Owusu,M; Oyebanji,VO.
Abstract Newcastle Disease (ND) has been identified as a major constraint to local poultry production with its impact being felt more in rural poultry production which forms about 80% of Ghana poultry population. However documented evidence on ND virus activity in rural poultry in Ghana is still lacking. Hence, this study was conducted to evaluate the level of circulating antibodies against ND using the Haemagglutination Inhibition (HI) technique. Sera collected from unvaccinated 292 chickens and 153 guinea fowls randomly selected from households and a live bird market in Kumasi and its environs were evaluated for Newcastle disease virus antibodies. Results showed 81.8 % (239/292) of local chickens and 24.2 % (37/153) of guinea fowls tested positive for ND...
