Farmers Perception and Adaptation to Climate Change: An Estimation of Willingness to Pay

This paper assesses farmers’ perception and adaptation to climate change to enhance policy towards tackling the challenges climate change poses to the farmers in Ghana. With regards to farmers’ perception and methods of adaptation, majority of the farmers perceived increase in temperature and decrease in rainfall pattern. Farmers’ level of adaptation was found to be relatively high with majority of the farmers using changing planting dates, different crop varieties, soil conservation and water harvesting as the major adaptation measures to climate change impacts. However, access to water, high cost of adaptation, lack of information, lack of knowledge on adaptation, insecure property rights, insufficient access to inputs and lack of credits were identified as the major barriers to adaptation. The probit regression estimation results indicated that the probability of willingness to pay for climate change mitigation policies increases with age, years of education and ownership of farm land.Perception, adaptation, climate change, willingnessto pay, probit regression, Agricultural and Food Policy, Farm Management, Production Economics, Productivity Analysis, GA, IN,

Productivity of hired and family labour and determinants of technical inefficiency in Ghana's fish farms

This paper examines the productivity of hired and family labour and determinants of technical inefficiency of fish farms in Ghana. A modified Cobb-Douglas stochastic frontier production function which accounts for zero usage of family and hired labour is employed on cross-sectional data of 150 farmers collected in 2007. The results reveal that family labour, hired labour, feed, seed, land, other cost and extension visit have reasserting influence on fish farm production. Findings also show that family and hired labour used for fish farming production in Ghana may be equally productive. The combined effects of operational and farm specific factors (age, experience, land, gender, pond type and education) influence technical inefficiency although individual effects of some variables may not be significant. Mean technical efficiency is estimated to be 79 percent. Given the present state of technology and input level, the possibility of enhancing production can be achieved by reducing technical inefficiency by 21 percent through adoption of practices of the best fish farm. --Ghana,fish farms,technical inefficiency,hired and family labour,stochastic frontier.

Productivity and Technical Efficiency of Cocoa Production in Eastern Ghana

This paper analyzes the productivity, technical efficiency and its determinants among cocoa producers in the Eastern region of Ghana. A multi-stage random sampling technique is used to obtain a cross sectional data on 190 respondents. The stochastic frontier model is adopted to analyze the research objectives. The results reveal that productivity level of cocoa responds positively to land size, the level of agrochemical, labour and intermediate input used. However, productivity responds negatively to the increasing age of the cocoa trees. Cocoa producers in the region exhibit decreasing returns to scale. The mean technical efficiency among the cocoa producers is estimated to be 85%, indicating that the possibility of enhancing production given the present state of technology and input level can be achieved in the short run by increasing technical efficiency by 15% through adoption of practices of the best cocoa farm. Exogenous factors such as access to extension services, technical support and credit are found to reduce the level of technical inefficiency among the producers. Also older farmers and male farmers are   efficient than younger and female farmers. Farmers with more experience in cocoa production also produce with technical  efficiency. Key words: Cocoa, productivity, technical efficiency, stochastic frontier, Ghana

IMPACT OF CROP PRODUCTIVITY ON POVERTY AMONG FARM HOUSEHOLDS IN GHANA

Ghana Poverty Reduction Strategy I & II sought to increase crop productivity to reduce high poverty incidence in farm sector, but the magnitude of impact of the productivity on poverty is not present in all agro-ecological zones in Ghana. The aim of the study is to estimate poverty headcount ratio, poverty gap and poverty severity, and link crop productivity to poverty according to agroecology subject to a two-step instrumental variable regression technique using Pseudo Panel data from the Ghana Living Standards Survey (GLSS rounds 5 & 6). Farmers’ poverty headcount ratio, poverty gap, and poverty severity reduced from 57%, 25%, and 14% in 2005 to 37%, 14%, and 7% in 2013 respectively. The result further indicates that 1% growth in crop productivity reduces the probability of poverty headcount ratio, poverty gap and poverty severity by 0.28%, 0.38% and 0.75% respectively in all agro-ecological zones. Additionally, the paper shows that education, livestock and remittance income reduces poverty, while household size and great distance to access water increase poverty differently from agro-ecology. The study recommends rapid crop productivity growth by prioritizing technology adoption and institutional coordination to suit agro-ecological conditions among the poor, illiterate and non-partisan

Food and Cash Crop Productivities and Poverty Reduction in Ghana

Food and cash crop productivities growth provide food and improve smallholder farmers income to reduce poverty Crop farmers poverty rate is disaggregated into food and cash crop type but beyond 2006 the poverty rate is not disaggregated which is addressed by this study Food and cash crops have different growth paths and unequal pathways towards poverty The paper estimates the poverty rates among food and cash crop farmers and examines their productivities effect on povert

Performance of Fish Farms in Ghana - A Stochastic Frontier Approach

This study applies the single-stage modelling stochastic frontier approach to assess the performance of fish farms in Ghana. It examines technical efficiency and its determinants of 150 farms surveyed in 2007 and extend the scope of the analysis to explore interactive effects of farm specific variables on efficiency of production. Findings demonstrate that expected elasticities of mean output with respect to all input variables are positive and significant. Computed return to scale reveals that fish farms in Ghana are characterised by technology with increasing return to scale. The combined effects of operational and farm specific factors are found to influence efficiency. The study further reveals that inclusion of interaction between some exogenous variables in the inefficiency model is significant in explaining the variation in efficiency. Comparison of mean technical efficiency according to regions did not show any significant variation. Overall mean technical efficiency is estimated to be 80.8%.Keywords: Aquaculture Efficiency and Management, Aquaculture, Fisheries Economic

Value Chain Analysis of the Broiler Industry in the Southern Sector of Ghana

The livestock subsector especially broiler production plays a significant role in the livelihood and food security in Ghana. Several researchers in developing nations have employed value chain methodologies to investigate the linkages and the interactions of the various actors in the poultry sector. However, none of these studies comprehensively captured each actor’s strengths, weaknesses, opportunities and threats, as well as the governance structure and profitability of the broiler industry. This paper fills this gap by analyzing the governance structure, value addition, determinants of profitability and prospect of the broiler industry using 290 respondents (180 broiler producers, 65 distributors and 45 retailers) from the Greater Accra, Ashanti and Bono Regions of Ghana. The study adopted the scoring analytical technique, net farm income (NFI), the modified Cobb-Douglas function and the SWOT (strengths, weaknesses, opportunities, threats) matrix for the analyses. The results revealed producers as the key governors with the highest value addition and return on investment. Distributors and processors on the other hand form informal cartels to monopolize their activities to increase bargaining power. Whilst credit access, education, business training, age and feed type influenced profitability, the broiler industry is threatened by high importation of frozen chicken, high taxes, lack of capital access and high cost of operation. The study recommends that the government should pursue measures to minimize the cost of operations through input-tax exemptions and reduce the importation of chicken products. Stakeholders should invest in input supply, processing technologies and transportation facilities to boost local production for profit gains

Is resilience socially constructed? Empirical evidence from Fiji, Ghana, Sri Lanka, and Vietnam

The objective of this paper is to better understand the various individual and household factors that influence resilience, that is, people⬢s ability to respond adequately to shocks and stressors. One of our hypotheses is that resilience does not simply reflect the expected effects of quantifiable factors such as level of assets, or even less quantifiable social processes such as people⬢s experience, but is also determined by more subjective dimensions related to people⬢s perceptions of their ability to cope, adapt or transform in the face of adverse events. Data collected over two years in Fiji, Ghana, Sri Lanka and Vietnam confirms the importance of wealth in the recovery process of households affected by shocks and stressors. However our results challenge the idea that within communities, assets are a systematic differentiator in people⬢s response to adverse events. The findings regarding social capital are mixed and call for more research: social capital had a strong positive influence on resilience at the community level, yet our analysis failed to demonstrate any tangible positive correlation at the household level. Finally, the data confirm that, like vulnerability, resilience is at least in part socially constructed, endogenous to individual and groups, and hence contingent on knowledge, attitudes to risk, culture and subjectivity

Smallholder Cocoa Farmers Access to On/Off-Farm Support Services and its Contribution to Output in the Eastern Region of Ghana

It has been established that smallholder farmers have minimal access to various support services that would have otherwise enabled them to increase their output levels. The focus of this paper is to identify and quantify the impact of various support services on the production levels of cocoa in the Eastern region of Ghana. A cross sectional survey of 190 cocoa farmers was obtained using a two-stage sampling technique (purposive and random). Descriptive statistics and an OLS regression model were used to analyse and discuss the results of the study. The various support services identified included labour services, financial services, technical assistance, farmer group support services, Research and Development (R&D) institutional support services, extension services and input support services. The services that significantly influenced output levels of cocoa were extension services, labour supply and technical assistance, among other variables including farm size and quantity of agrochemical used. It is recommended that access to these support services be improved in order to realise an increase in output for the smallholder cocoa farmer
