The purpose of this paper is to investigate the characteristics of crop-livestock diversification among smallholders in the forest-savannah agroecological zone of Ghana.

The study uses a stochastic input distance function to investigate the evidence of economies of diversification and its effect on determining diversification decisions of smallholders in Ghana. Furthermore, this study also explores evidence of scale economies in integrated crop-livestock systems among smallholder farmers.

The empirical results show that economies of diversification are significant in determining diversification decisions of smallholders. The economies of scale are evident in integrated crop-livestock systems in Ghana, suggesting that opportunities exist to expand crop-livestock outputs without employing additional inputs or improved production technologies. Crop-livestock diversification is a desirable strategy for improving overall farm productivity among smallholders in Ghana. Economies of diversification were found to be significant among the output combinations, maize with other crops and other crops with livestock, in integrated crop-livestock production systems.

This study is based on a cross-sectional data set. Hence, the findings may be subject to some limitations; however, the authors have sought to minimise such limitations.

The results imply that crop-livestock diversification is a desirable strategy for improving overall farm productivity. Therefore, the findings are useful for policymakers to design appropriate strategies for enhancing the production of specific output combinations in crop-livestock diversification systems among smallholders in Ghana. Specifically, such policies should promote the production and integration of crops such as legumes with other crops, and livestock with other crops in diversified farming systems to enhance overall farm productivity. This will reduce food insecurity and poverty among rural farm households and the entire rural population.

These results indicate that to improve crop-livestock productivity through diversification, and reduce the effect of climate variability, it is imperative to provide the enabling environment that will facilitate and encourage production of these output combinations among smallholders in Ghana. The empirical results enhance the literature by providing empirical evidence of the complementary synergies and economies of diversification in integrated farming systems and, hence, make recommendations for improving these farming systems.

The purpose of this paper is to investigate farmers’ risk aversion using the equally likely certainty equivalent approach and the negative exponential utility function to identify risk preference classification.

Stochastic efficiency with respect to a function is applied to determine the risk efficient farming systems for the farmers in central and north-east regions of Thailand.

The study results showed that maize followed by sorghum is the most risk efficient farming system for the extremely risk averse rain-fed farmers in the central region of Thailand. Intensive planting of wet rice and dry rice cultivation is preferred by the extremely risk averse central region irrigated farmers. Wet rice and cassava together with raising small herd of cattle is the most economically viable farming system for the extremely risk averse rain-fed farmers in the north-east region, while two rice crops with raising cattle is preferred by the extremely risk averse north-east irrigated farmers of Thailand.

The findings of this study provide useful information to reinforce the empirical basis for risk analysis for Thai farmers. The results will provide more accurate information regarding risk at the farm level to policy makers and researchers.

The purpose of this systematic review was to assess the determinant factors of climate change adaptation (CCA) in sub-Saharan Africa (SSA).

Studies that focused on determinant factors of CCA by crop–livestock farmers and pastoralists in SSA and written in English were reviewed from five major databases using the applications of Endnote and NVivo. The review process followed a sequence of steps to reach into the final selection.

A total of 3,028 papers were recovered from the databases and screened for duplicates (777) and publications before 2000 (218). The titles and abstracts of 2,033 papers were reviewed, and 1,903 of them were excluded owing to preliminary exclusion criteria. Finally, 130 papers were selected for full-text review and more detailed assessment, where 36 papers qualified for the final review. The most important determinant factors of CCA by pastoralists were household income, access to information, access to extension services, government support and access to market. In the case of agro-pastoralists, access to information, household income, age and land/livestock ownership were found as the major determinant factors. Household income, land ownership, access to information, farm size, household size and access to extension services were the determinant factors found for CCA by smallholder farmers.

This systematic review identified the major determinant factors according to production systems and highlights the importance of considering specific factors in designing CCA strategies.

After clearly stating the research question, a literature search was conducted from the major databases for climate-related research, and a comprehensive search was performed by two independent researchers.

In order to improve access to resources for smallholder farmers, efforts are being made to promote contract farming in Ghana. This is seen as a strategy to increase agricultural productivity of farmers, give better market access and guarantee adequate supply of raw materials to agro-based industries. However, the challenge is whether contract farming leads to improvement in food security status of farmers. The study therefore seeks to explore to what extent farmers' food security status is influenced by their participation in contract farming activities.

Using Cragg's double-hurdle model to analyse participation in contract farming, the authors control for selection bias using propensity score matching applied to a data set of 336 observations to examine the impact of contract farming on the food security levels of rice farmers in Ghana.

The results of this study show that yield of paddy and the wealth of the farmer are the main factors that influence the quantity of paddy rice to be contracted in contract farming arrangements. This study also finds that participation in contract farming will increase food security by 109%. In conclusion, contract farming has a significant positive impact on the farmers' food security status.

Agricultural policies and rural development initiatives supporting the promotion and expansion of contract farming should be pursued to persuade more farmers to produce under contract farming agreements.

This study investigates implications of crop and income diversifications on consumption expenditure (welfare) of rice-producing households in Ghana. It further compares diversification by three rice production systems: two-season rain-fed, two-season irrigated and one-season rain-fed rice production.

Primary data were sourced from 225 rice farmers. Margalef index and three-stage least-squares were employed.

Majority of rice-farming households in Ghana diversify livelihoods. The extent of livelihood diversification differs among two-season rain-fed, two-season irrigated and one-season rain-fed rice-producing households. Credit, distance to district capitals, production purpose and number of farming seasons influence crop and income diversifications, and consumption expenditure of rice-producing households. While crop diversification reduces consumption expenditure, income diversification increases it. Crop and income diversifications positively influence each other. Consumption expenditure reduces crop diversification but increases income diversification.

Policy should be directed towards the promotion of more livelihood activities to boost rice farmers' welfare. There should be awareness creation and training programmes to enable rice farmers realize different economic activities within and outside the agricultural value chain.

Crop and income diversifications were measured as continuous response variables, unlike previous studies that used a binary response variable. The authors established a synergy among crop and income diversifications, and consumption expenditure (welfare). The authors further compared crop and income diversifications by three rice production systems: two-season rain-fed, two-season irrigated and one-season rain-fed rice production systems.

The purpose of this paper is to examine the factors influencing the choice and the amount of cocoa beans sold to public and private licensed buying companies in the Western North of Ghana.

The study was conducted in the Western North of Ghana. Cragg’s Double Hurdle model was used to examine the factors influencing the choice of licensed buying company (LBC) whereas Kendall’s coefficient of concordance was employed in analysis of the marketing challenges.

The results showed that non-price incentives determine the choice and the amount cocoa beans sold to an LBC. Specifically, education, years of experience in cocoa farming and timely payment of sold cocoa beans positively influence the choice of public LBC. However, off farm job participation, provision of credit facilities and extension services affect the choice of private LBC as marketing outlet. Perceived low price of cocoa beans, inadequate credit support, and adjustment of scales used in weighing of cocoa beans were identified as the most important challenges confronting farmers.

The research provides important information on non-price incentives influencing cocoa marketing outlet decision as well as the marketing challenges faced by farmers which can contribute to improving internal marketing efficiency of the cocoa industry in Ghana. Besides, this study also extends the frontiers in terms of methodological approach by adopting Cragg’s Double Hurdle Model in addressing the research question.

This paper aims to investigate how awareness influences the adoption of positive selection (PS) technology among smallholder yam farmers in West Africa. PS has the potential of increasing yield and reducing disease incidence and severity in yam production.

This paper applies the average treatment effect (ATE) methodology to estimate the rates of awareness and adoption of the PS technology and associated factors using data from 678 smallholder seed yam farmers in Ghana and Nigeria.

The results indicate that the actual adoption rates of PS technology are 58 and 55%, while the potential adoption rates are estimated at 89.5 and 79.3% for Ghana and Nigeria, respectively, if the PS technology was fully disseminated. This leads to adoption gaps of 31.7 and 24.8%, respectively, for Ghana and Nigeria stemming from incomplete awareness of the PS among the population of yam growing farmers. The PS adoption is high among the educated young farmers who are members of farmer based organizations and participate in demonstrations.

Promotional efforts for enhancing awareness and adoption of PS should target educated youth willing to participate in field demonstrations and should focus on scaling up of PS technology to ensure quality farmer saved seed yams and enhance yam productivity in West Africa.

The introduction of PS in seed yam production is quite recent also its introduction to seed yam farmers in West Africa. Subsequently, a better understanding of what the adoption status would be should everyone in the population of yam farmers are aware of PS is vital for policy, research and development.

The purpose of this paper is to support the development of effective strategies that enhance community water supply systems. The study examined service constraints and willingness to pay for better services in community-managed water supply services using empirical evidence from beneficiaries of a small-town water supply system in Ghana.

A survey design of both descriptive and exploratory research is adopted, the descriptive survey handles the quantitative aspect, while the exploratory survey handles the qualitative aspect. The authors collected data using a structured survey questionnaire from 387 beneficiaries who were public standpipe and domestic users. Descriptive statistics, Kendall's coefficient of concordance and Cragg's two-step model were the methods of analysis employed.

The respondents ranked lack of capacity (managerial) as the topmost constraint of the community-managed water system. The findings indicate that 57% of the beneficiaries were not willing to pay, whiles 43% were willing to pay. Also, results from Cragg's two-step regression model indicate that different sets of factors affect willingness-to-pay and amount-to-pay decisions. The study revealed that while a willingness-to-pay decision is influenced by income, education, marital status and customer service, the estimated-amount-to-pay decision is more influenced by income and education.

Building on the empirical evidence, the findings indicated that the water and sanitation management team can increase the current fee of GH¢ 5.00/1 m³ (≈US$ 0.87) by increasing beneficiaries charge for a bucket of water from GH¢ 0.10p (≈US$ 0.017) to GH¢ 0.21p (≈US$ 0.036) for better services within the community. Importantly, the additional charge should take into consideration income and education which were noted to significantly influence the beneficiary's amount-to-pay decision for better services in the community-managed water supply system.

This paper aims to understand the perception of smallholder farmers on climate change, identify major livestock related climate change adaptation (CCA) strategies and their determinants in selected neighboring districts of Tigray and Amhara regions of Ethiopia.

A total of 416 household heads were involved in a questionnaire survey using a multistage sampling approach. To understand the socio-economic factors that influence farmers’ perception on climate change (CC) and/or variability, a binary logit model was used. Multinomial logit model was used to identify the determinants of smallholder farmers’ choices of adaptation strategies.

Milk reduction, weight loss, feed shortage and frequent animal disease outbreak were indicated as major impacts of CC on livestock production. About 86.2% of the farmers’ exercise CCA measures where livestock health care and management (25%), followed by livelihood diversification (21.5%) and shifting and diversification of livestock species (20.9%) were the top three adaptation measures implemented. Education, knowledge on CCA strategies, access to veterinary service and extension, market access, annual income, non-farm income, total livestock unit, sex of household head and household size were the major determinant factors to farmers’ choice of CCA.

Concerned authorities working in CC related sectors should give due attention to improve smallholder farmers’ access to extension and veterinary services, market access and climate information to enhance their adaptive capacity to CC impacts. In addition, incorporating climate change awareness trainings into the existing extension packages is crucial to enhance the awareness of farmers on climate change and implement appropriate adaptation strategies. Moreover, it is very essential to provide appropriate herd management and marketing strategy based on the production system to avoid the significant price reduction during drought periods.

Contemporary literature reveals that, to date, the poultry livestock sector has not received sufficient research attention. This particular industry suffers from unstructured supply chain practices, lack of awareness of the implications of the sustainability concept and failure to recycle poultry wastes. The current research thus attempts to develop an integrated supply chain model in the context of poultry industry in Bangladesh. The study considers both sustainability and supply chain issues in order to incorporate them in the poultry supply chain. By placing the forward and reverse supply chains in a single framework, existing problems can be resolved to gain economic, social and environmental benefits, which will be more sustainable than the present practices.

The theoretical underpinning of this research is ‘sustainability’ and the ‘supply chain processes’ in order to examine possible improvements in the poultry production process along with waste management. The research adopts the positivist paradigm and ‘design science’ methods with the support of system dynamics (SD) and the case study methods. Initially, a mental model is developed followed by the causal loop diagram based on in-depth interviews, focus group discussions and observation techniques. The causal model helps to understand the linkages between the associated variables for each issue. Finally, the causal loop diagram is transformed into a stock and flow (quantitative) model, which is a prerequisite for SD-based simulation modelling. A decision support system (DSS) is then developed to analyse the complex decision-making process along the supply chains.

The findings reveal that integration of the supply chain can bring economic, social and environmental sustainability along with a structured production process. It is also observed that the poultry industry can apply the model outcomes in the real-life practices with minor adjustments. This present research has both theoretical and practical implications. The proposed model’s unique characteristics in mitigating the existing problems are supported by the sustainability and supply chain theories. As for practical implications, the poultry industry in Bangladesh can follow the proposed supply chain structure (as par the research model) and test various policies via simulation prior to its application. Positive outcomes of the simulation study may provide enough confidence to implement the desired changes within the industry and their supply chain networks.
