Environmentally induced farmer migration is an important livelihood strategy, yet little is known of the effects on the destination region agroecosystem information networks and management practices. In the forest-savanna transition zone (Brong Ahafo Region) of Ghana, where migration from northern regions (migrant) and from neighboring regions (settler) is active, we chart the role of migrant famers and the type of agroecosystem management practices embedded in information networks using a social networks approach. Based on empirical network data from 44 respondents across three communities, we illustrate a diffuse information network, with variable tie frequency between settlement categories (local, settler, or migrant) of farmers. The cohesion of this...

Participation, politics, and panaceas: exploring the possibilities and limits of participatory urban water governance in Accra, Ghana
Provedor de dados: Ecology and Society
Autores: Morinville, Cynthia; The University of British Columbia, Institute for Resources, Environment and Sustainability; cynthia.morinville@gmail.com; Harris, Leila M; The University of British Columbia, Institute for Resources, Environment and Sustainability; lharris@ires.ubc.ca.
Water governance debates have increasingly recognized the importance of adaptive governance for short- and long-term sustainability, especially with respect to increasing climate unpredictability and growing urbanization. A parallel focus on enhancing community participation pervades international development recommendations and policy literature. Indeed, there are often implicit and explicit connections made between the participatory character of water governance institutions and their adaptive capacity.  The social-ecological systems literature, however, has also urged caution with respect to embracing panaceas, with increasing calls to be attentive to the limitations of proposed &amp;#8220;solutions.&amp;#8221; We discuss the parallels between the...

Transfer of Knowledge on Agroforestry Management Practices:  the Structure of Farmer Advice Networks
Provedor de dados: Ecology and Society
Autores: Isaac, Marney E; University of Toronto; marney.isaac@utoronto.ca; Erickson, Bonnie H; University of Toronto;; Quashie-Sam, S. James; Kwame Nkrumah University of Science and Technology, Ghana;; Timmer, Vic R; University of Toronto;.
Access to knowledge on farm management practices is essential for the maintenance of productive agroforestry systems.  Farmers who lack the means to acquire farming knowledge from formal sources often rely on information within their informal social networks.  However, little research has explored the explicit structure of farmer communication patterns.  We examined advice network structures by using farmer attributes, i.e., kin relationships, community involvement, and imitation, to characterize structural positions and investigated the consequences of such structure on farming practices in cocoa agroforestry systems in Ghana, West Africa.  Furthermore, we used a multicommunity approach; we constructed networks for four communities to increase replication...

Autores: Mees, G.F.
Currently, the type locality of Pteronetta hartlaubii is considered to be the Camma River, Gabon, but this is an error, and must be Rio Boutry, Gold Coast (now Ghana), where the holotype was obtained by H.S. Pel. In a note, reference is made to a few other specimens obtained by the collectors Pel and Nagtglas which in recent literature have been overlooked.

The early specimens of the potto Perodicticus potto (Statius Müller, 1776) in the National Museum of Natural History, Leiden, with the selection of a neotype
Provedor de dados: Naturalis Digital Academic Repository
Autores: Smeenk, C.; Godfrey, L.R.; Williams, F.L.
The potto was first recorded and figured by Willem Bosman in 1704. The name Lemur potto Statius Müller, 1776 is exclusively based upon Bosman’s account and figure, which are reproduced in full. The type locality is Elmina on the Gold Coast, the present Ghana. No type specimen was collected. The early pottos in the Leiden Museum are listed and their history is given, with special reference to the animals obtained by H.S. Pel. The publications on this material are reviewed. An adult female, RMNH 39375: mounted skin and skeleton acquired by Pel in 1849 at Dabocrom (Dabo Krom) near Sekondi, coastal Ghana, is designated the neotype of Lemur potto Statius Müller, 1776. The neotype is extensively described and figured. Taxonomic notes on the putative (sub)species...

Notes on Micractaeon, a monotypic genus of African land snails (Gastropoda Pulmonata: Ferussaciidae?)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Bruggen, A.C. van; Winter, A.J. de.
Micractaeon kakamegaensis Verdcourt, 1993 (type loc. Kenya, Kakamega Forest), is a synonym of Pseudopeas koptawelilense Germain, 1934 (type loc. Kenya, Mt. Elgon); the proper name is therefore Micractaeon koptawelilensis (Germain, 1934). New anatomical data are supplied, more or less confirming classification in the family Ferussaciidae. The shell is subject to some considerable variation in size, shape and sculpture. The species appears to be widely distributed in various types of forest in tropical Africa (Ghana, Cameroon, eastern and south-eastern Zaïre, Kenya, Malawi, and eastern Zambia); hypsometrical distribution is generally from c. 950 m to c. 2300 m, although in Ghana it has been collected at altitudes of between &amp;lt; 250 and c. 700 m.

In the present study, we screened blood DNA samples obtained from cattle bred in Brazil (n=164) and Ghana (n=80) for Babesia bovis using a diagnostic PCR assay and found prevalences of 14.6% and 46.3%, respectively. Subsequently, the genetic diversity of B. bovis in Thailand, Brazil and Ghana was analyzed, based on the DNA sequence of merozoite surface antigen-1 (MSA-1). In Thailand, MSA-1 sequences were relatively conserved and found in a single clade of the phylogram, while Brazilian MSA-1 sequences showed high genetic diversity and were dispersed across three different clades. In contrast, the sequences from Ghanaian samples were detected in two different clades, one of which contained only a single Ghanaian sequence. The identities among the MSA-1...

Study of the structure and dynamics of demersal fish assemblages on the continental shelf and upper slop off Ghana, West Africa
Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Koranteng, K.A.
Using two-way indicator species analysis and detrended correspondence analysis,  species on the continental shelf and upper slope of Ghana were classified into six assemblages.  The structure of the assemblages is determined primarily by depth and type of sediment on the seabed. There are clear faunal discontinuities around 30-40 m, 100 m and 200 m depth.  The dynamics of the assemblages are influenced by physico-chemical parameters of the water masses, mainly temperature, salinity and dissolved oxygen which are periodically modified by the seasonal coastal upwelling that occurs in the area. The observed changes in the composition and relative importance of species in the assemblages can be related to increased fishing activity and environmental forcing.

Potential Impacts of a Green Revolution in Africa – the Case of Ghana
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Breisinger,   Clemens; Diao,   Xinshen; Thurlow,   James; Al-Hassan,   Ramatu M.
Agricultural growth in Africa has accelerated, yet most of this growth has been driven by land expansion. Land expansion potential is reaching its limits, urging governments to shift towards a green revolution type of productivity-led growth. Given the huge public investments required, this paper aims to assess the potential impacts of a green revolution. Results from a CGE model for Ghana show that green revolution type growth is strongly pro-poor and provides substantial transfers to the rest of the economy, thus providing a powerful argument to raise public expenditure on agriculture to make a green revolution happen in Africa.

Cost Implications of Agricultural Land Degradation in Ghana: An Economywide, Multimarket Model Assessment
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Diao,   Xinshen; Sarpong,   Daniel Bruce.
An economywide, multimarket model is constructed for Ghana and the effects of agricultural soil erosion on crop yields are explicitly modeled at the subnational regional level for eight main staple crops. The model is used to evaluate the aggregate economic costs of soil erosion by taking into account economywide linkages between production and consumption, across sectors and agricultural subsectors. To fill a gap in the literature regarding economic cost analysis of soil erosion, this paper also analyzes the poverty implications of land degradation. The model predicts that land degradation reduces agricultural income in Ghana by a total of US$4.2 billion over the period 2006–2015, which is approximately five percent of total agricultural GDP in these ten...

AN EXAMINATION OF PROFIT INEFFICIENCY OF RICE FARMERS IN NORTHERN GHANA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Abdulai,   Awudu; Huffman,   Wallace E.
This paper employs a stochastic frontier model to examine profit inefficiency of rice farmers in the Northern Region of Ghana using farm-level survey data. The efficiency index, based on a half-normal distribution of the stochastic error term is related to farm and household characteristics. The empirical results show that farmers' human capital represented by the level of schooling contributes positively to production efficiency, suggesting that investment in farmers' education improves their allocative performance. Access to credit and greater specialization in rice production, are found to be positively related to production efficiency. A farmer's participation in nonfarm employment and being older, however, reduce production efficiency.  Farmers...

Autores: Breisinger,   Clemens; Diao,   Xinshen; Thurlow,   James; Yu,   Bingxin; Kolavalli,   Shashidhara.
Ghana is an emerging success story in Africa and in a couple of years will become the first African country to achieve the first Millennium Development Goal of halving its national poverty rate. The government of Ghana has therefore extended its development vision and recently declared the goal of reaching middle-income-country (MIC) status by 2015. To analyze possible pathways and implications of achieving MIC status, this paper examines other countries’ experiences on their way to becoming MICs and emphasizes the important role of growth acceleration, export diversification, and economic structural change in the transformation process. The paper further analyzes Ghana’s growth options and their structural implications using a dynamic computable general...

Modelling the Fiscal Effects of Aid: An Impulse Response Approach for Ghana
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Morrissey,   Oliver; Osei,   Robert; Lloyd,   Tim A.
An important feature of aid to developing countries is that it is given to the government. As a result aid has the potential to affect budgetary behaviour. Although the (albeit limited) aid-growth literature has addressed the effect of aid on policy, it has tended to neglect the effect of aid on the fiscal behaviour of governments. While fiscal response models have been developed to examine the effects of aid on fiscal aggregates - taxation, expenditure and borrowing - the underlying theory is ad hoc and empirical methods used are subject to severe limitations. This paper applies techniques developed in the "macroeconometrics" literature to estimate the dynamic structural relationship between aid and fiscal aggregates. Using vector autoregressive methods,...

Assessing Rural Women Food Producers Capacity to Adopt Modern ICTs – A case Study of the Mfantsiman District of Ghana
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sampong,   D.D.; Egyir,   Irene Susana; Yaw,   Osei-Asare.
The traditional way of information dissemination has been through people; the modern way is through the electronic media – improved information and communication technologies (ICTs).  For effectiveness, modern ICTs should help women to improve on their income generating capacity.  Issues of level of resource capacity of women, information needed, and current sources of such information become important.  This study sought to investigate the issues above with respect to rural women food producers in the Mfantsiman District of Ghana.  Simple descriptive statistics and econometric models were employed in the data analysis of 91 randomly selected respondents.  The results of the study showed that: In general, the women food producers were aged, subsistence...

Productive Benefits of Health: Evidence from Low-Income Countries
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)

Various household survey indicators of adult nutrition and health status are analyzed as determinants of individual wages. However, survey indicators of health status may be heterogeneous, or a combination of health human capital formed by investment behavior and variation due to genotype, random shocks, and measurement error, which are uncontrolled by behavior. Although there are no definitive methods for distinguishing between human capital and genetic variation in health outcomes, alternative mappings of health status, such as height, on community health services, parent socioeconomic characteristics, and ethnic categories may be suggestive. Instrumental variable estimates of health human capital and residual sources of variation in measured health...

Has Imported Rice Crowded-out Domestic Rice Production in Ghana? What has Been the Role of Policy?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Asuming-Brempong,   Samuel; Osei-Asare,   Yaw Bonsu.
Commercial rice imports have accounted for approximately 61%, food aid in rice accounted for about 2%, and domestic rice accounted for some 37% per annum of rice consumption in Ghana over the four years between 2000 and 2003. Compared to the 1990s, these figures show a gradual decline in the share of local rice production in the total quantities of rice consumed in the country. On the other hand, the proportion of food aid in rice consumed has remained relatively constant over the period, while the proportion of commercial imports has increased steadily. Using the Engel-Granger residual-based co-integration test, a market integration analysis was explored for imported rice and domestic rice which compared a central market for imported rice and five key...

An Empirical Investigation of Short and Long-run Agricultural Wage Formation in Ghana
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Abdulai,   Awudu; Delgado,   Christopher L.
This paper investigates empirically the factors that influence real agricultural wage rates in Ghana, based on 1957 to 1991 data. The Johansen cointegration framework is used to examine long-run relationships among agricultural and urban wage rates, the domestic terms of trade between agriculture and nonagriculture, urban unemployment, capital stock in agriculture and the size of the rural population. An error correction model is then used to investigate short-run dynamic relationships among the variables. The results show that: (1) there is only one stable equilibrium relationship among agricultural wage rates and their determinants in the long-run; (2) a 1 percent change in the domestic terms of trade between agriculture and non-agriculture leads to a...

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?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: 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 overseas trade between SSA countries and the USA, EU and the BRIC countries. The difficulty of commodity arbitrage across international borders SSA is however a fundamental constraint to price transmission, market integration and the realisation of the welfare-enhancing role of cross-border trade in Africa. This study examines the impact of border and distance on price transmission between tomato markets in Ghana and Burkina-Faso. The analysis applies a regime-switching vector error correction model to estimate semi-weekly, wholesale prices of tomato in four tomato markets in...

This paper provides a nuanced perspective on debates about the potential for Africa’s smallholder agriculture to stimulate growth and alleviate poverty in an increasingly integrated world. In particular, the paper synthesizes both the traditional theoretical literature on agriculture’s role in the development process and discusses more recent literature that remains skeptical about agriculture’s development potential for Africa. In order to examine in greater detail the relevance for Africa of both the “old” and “new” literatures on agriculture, the paper provides a typology of African countries based on their stage of development, agricultural conditions, natural resources, and geographic location… More broadly, the paper demonstrates that conventional...

This chapter discusses the implementation challenges of the WHO Guidelines on safe wastewater use pertaining to the adoption of the so-called ‘post-treatment’ or ‘non-treatment’ options, like safer irrigation practices or appropriate vegetablewashing in kitchens. Due to limited risk awareness and immediate benefits of wastewater irrigation, it is unlikely that a broad adoption of recommended practices will automatically follow revised policies or any educational campaign and training. Most of the recommended practices do not only require behaviourchange but might also increase operational costs. In such a situation, significant efforts are required to explore how conventional and/or social marketing can support the desired behaviour-change towards the...

ARE WEALTH TRANSFERS BIASED AGAINST GIRLS? GENDER DIFFERENCES IN LAND INHERITANCE AND SCHOOLING INVESTMENT IN GHANA'S WESTERN REGION
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Quisumbing,   Agnes R.; Payongayong,   Ellen M.; Otsuka,   Keijiro.
This study attempts to analyze changing patterns of land transfers and schooling investments by gender over three generations in customary land areas of Ghana's Western Region. Although traditional matrilineal inheritance rules deny landownership rights to women, women have increasingly acquired land through gifts and other means, thereby reducing the gender gap in landownership. The gender gap in schooling has also declined significantly, though it persists. We attribute such changes to the increase in women's bargaining power due to an agricultural technology that increased the demand for women's labor, contributing to the reduction of "social" discrimination as well as weak "parental" discrimination.

Seasonal Asymmetric Price Transmission in Ghanaian Tomato Markets: Adapting Johansen’s Estimation Method
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Amikuzuno,   Joseph; Ihle,   Rico.
We assess market integration and price transmission of perishable agricultural produce in Sub-Saharan Africa by studying Ghanaian tomato markets which are characterized by pronounced seasonality in production and trade flows. We analyse the tomato markets of Ghana by simultaneously regarding its five most important markets, Navrongo, Techiman, Kumasi, Tamale and Accra, in a multivariate asymmetric price transmission framework. The estimation of the model is based on a unique dataset and on a modified version of the Johansen estimation procedure which is suitable for estimating such multivariate models. We estimate the price transmission parameters for four regimes which are a combination of the seasonal patterns in trade flows and asymmetries in the...

Spatial Price Transmission Analysis in Agricultural Markets: Does the Data Frequency Improve our Estimation?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Amikuzuno,   Joseph.
Unavailability of high frequency, weekly or daily data compels most studies of price transmission in developing countries to use low frequency, monthly data for their analyses. Analyzing price dynamics with monthly data may however yield imprecise price adjustment parameters and lead to wrong inferences on price dynamics. This is because agricultural markets in developing countries operate daily or weekly. In this paper, we investigate the relevance of data frequency in price transmission analysis. We use a standard- and a threshold vector error model to estimate and compare price adjustment parameters for a high frequency, semi-weekly, data and a low frequency, monthly data. The results reveal that adjustment parameters estimated from the low frequency...

THE DEMAND FOR COMMODITY INSURANCE BY DEVELOPING COUNTRY AGRICULTURAL PRODUCERS: THEORY AND AN APPLICATION OF COCOA IN GHANA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Sarris,   Alexander H.
The paper considers the benefit to agricultural producers from commodity price insurance that provides in every year, but in advance of the resolution of production and price uncertainty, a minimum price for a fixed or variable portion of production.  Under the assumption that producers do not change their long term production and income diversification pattern, the theoretical framework suggested leads to explicit formulas for the benefit from providing this type of insurance.  The theoretical framework is implemented for Ghana, using the GLSS data to specify various classes of cocoa producing households, and monthly price data for both domestic and international prices to formulate appropriate models for ascertaining price risks faced by producers....

Regional Disparities in Ghana:  Policy Options and Public Investment Implications
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Al-Hassan,   Ramatu M.; Diao,   Xinshen.
The development pattern in Ghana is characterised by a north-south divide in which the north lags far behind the south. Ghana has achieved sustained growth and poverty reduction during the 1990s, but such growth did not benefit the three poor northern regions and the development gap has increased between the south and north. One of the most important reasons is that much of the growth has been generated by export agriculture in which northern Ghana has little contribution if any. This paper sets out to identify avenues for pro-poor growth in Ghana, focussing on agricultural opportunities, particularly in northern Ghana. Using an economywide, multimarket model and based on time series production data between 1991 and 2000 and Ghana Living Standards Survey...

The Integration of Tomato Markets in Ghana with and without Direct Trade Flows
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Ihle,   Rico; Amikuzuno,   Joseph.
Spatial market equilibrium theory views trade flow as the driving force behind market integration. We assess spatial price transmission between domestic tomato markets in Ghana to ascertain whether spatial price transmission veritably depends on direct trade between markets, or whether other forces drive market integration. We analyze a unique data set on tomato trade consisting of semi-weekly price and trade flow data for the five most important Ghanaian markets for fresh tomato, which represents one of the most important commercially produced and consumed vegetables in the country. A regime-dependent vector error correction model is proposed to investigate this question, and the results are compared with those of a linear vector error correction model....

TOBIT ESTIMATION OF THE INTENSITY OF EXPORT SUCCESS OF HORTICULTURAL ENTERPRISES IN GHANA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Agyei-Sasu,   Felix; Egyir,   Irene Susana.
Purpose- The issue of export success and the ability to sustain oneself in international horticultural markets have become more critical in the recent global and economic downturn because of its significance to the economy and to actors in the horticultural export chain. The extent of success is even much critical for enterprises. Therefore this study establishes the factors which influence the intensity of export success which measures the extent of export success. Design- Primary data were collected from 52 managers and representatives of horticultural exporting firms through a semi-structured questionnaire. The tobit model was used to estimate the intensity of export success by horticultural enterprises in Ghana. Findings- The result indicates that,...

Analysis of farm household technical efficiency in Northern Ghana using bootstrap DEA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Abatania,   Luke N.; Hailu,   Atakelty; Mugera,   Amin W.
Crop production is the main source of livelihood for households in Northern Ghana. The government is committed to improving crop production and knowledge about the technical efficiency of crop farms is essential in guiding policy decisions. This paper examined the technical efficiency of 189 crop farms in Northern Ghana using data envelopment analysis (DEA) with bootstrapping. We found that bias-corrected average technical efficiency of the sample farms is 77.26%. The estimated scale efficiency is 94.21%. In a second stage regression, we found that hired labour, geographical location of farms, gender and age of head of household significantly affect technical efficiency. Policy implications of the results are discussed.

Gender and Poverty: New Evidence from 10 Developing Countries
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Quisumbing,   Agnes R.; Haddad,   Lawrence James; Pena,   Christine.
This paper presents new evidence on the association between gender and poverty based on an empirical analysis of 11 data sets from 10 developing countries. The paper computes income- and expenditure-based poverty measures and investigates their sensitivity to the use of per capita and per adult equivalent units. It also tests for differences in poverty incidence between individuals in male- and female-headed households using stochastic dominance analysis. Stochastic dominance analysis reveals that differences between male- and female-headed households among the very poor are not sufficiently large that one can conclude that one is unambiguously worse- or better-off, except for a few exceptions. When we use the method of endogenous bounds, persons in...

Local Impacts of a Global Crisis - Food Price Transmission and Poverty Impacts in Ghana
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Cudjoe,   Godsway; Breisinger,   Clemens; Diao,   Xinshen.
This paper takes a local perspective on global food price shocks by analyzing food price transmission between regional markets in Ghana. It also assesses the impacts of food price increases on various household groups. Taking the recent global food crisis as an example, we find that prices for domestic staples are highly correlated with prices for imported rice. However, price transmission between pairs of domestic regional markets is limited; it is complete for local rice and maize only when more rigorous cointegration analysis is applied. Our findings also show the important role of seasonality in the determination of market integration and price transmission. The welfare effect for households as consumers appears relatively modest at the aggregate...

What Does Liberalization without Price Competition Achieve? The Case of Cocoa in Ghana.
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Vigneri,   Marcella; Santos,   Paulo.
The deregulation of Ghana’s domestic cocoa supply chain that took place in the early 1990s was expected to bring competition among different private buyers and to generate a number of production incentives to the farmers.  Most notably, it was expected that competition would emerge by means of price bonuses and/or premiums over the guaranteed price.  However, this paper finds that price based competition mechanisms did not develop in the resulting domestic cocoa value chain.  Rather, the now increasing numbers of Licensed Buying Companies compete for cocoa supplies based on the provision of different services to farmers.  The availability of a number of outlets offers farmers the option to choose among those that can provide cash as well as credit.  The...

Assessing Consumer Willingness to Pay a Premium for Organic Food Product: Evidence from Ghana
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Owusu,   Victor.
This paper examines the willingness of consumers to pay a premium for organic food product with a contingent valuation data from urban Kumasi of Ghana. Consumer’s willingness to pay a premium is estimated with a bivariate Tobit model. The empirical findings indicate that apart from socioeconomic characteristics and consumer perceptions, product attributes tend to influence consumer preferences for organic water melon and lettuce. The estimated mean WTP premium for 1 kilogram of water melon is GH¢0.5554 (US$ 0.4575) and that of organic lettuce is GH¢1.2579 (US$1.0361).

IMPLICATIONS OF THE WORLD FOOD CRISES ON TRENDS OF LOCAL FOOD PRICES IN THE UPPER EAST REGION OF GHANA
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: 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
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: 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
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: 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
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: 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...

Autores: 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?
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: 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
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: 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.

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...

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
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: 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...

Autores: 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.

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...
