A 2014 Social Accounting Matrix (SAM) for Uzbekistan with a focus on the agricultural sector
(2021) Wieck, Christine; Bozorov, Abdurashid; Feuerbacher, Arndt
Social accounting matrices (SAMs) are the core underlying data for economy-wide simulation models such as computable general equilibrium models. This paper reports the development of a SAM for Uzbekistan for the year 2014. The last SAM developed for Uzbekistan is based on the year 2001 (Müller, 2006) and Uzbekistan is listed among the top ten countries by GDP and population by the Global Trade and Analysis Project for which a recent input-output is missing. The SAM documented in this technical paper is characterized by a detailed representation of the agricultural sector. Generally, data availability in Uzbekistan is a challenge and the development process had to rely on myriad data sources. The final SAM values are estimated using an information-theoretic, cross-entropy approach. Using a Bayesian perspective, the degree of uncertainty of cell entries’ prior values reflected the availability and quality of data sources. In total, this SAM consists of 88 accounts. There are 31 commodity accounts and 31 accounts describe economic activities of which 17 activities are part of the agricultural sector. The factor accounts comprise five types of labor, capital, and main natural resources: land and water. There are three household accounts, one government, and five tax accounts. The authors hope that this SAM will allow researchers to investigate research questions that are of high priority for Uzbekistan’s future economic development, particularly those related to the future role of agriculture and water.
Animal welfare in non-anthropocentric cost-benefit analysis and social welfare functions: A critical review to guide practical application
(2024-10) Dusel, Sara; Wieck, Christine
Cost-benefit analysis and social welfare functions are two closely related methods to evaluate impacts of policies on humans (producers, consumers etc.) and animals. In cost-benefit analysis, the impacts on animals are currently either disclosed as intangible impacts or monetised from the human (anthropocentric) perspective through production costs, revenues and willingness to pay. Social welfare functions are more flexible to aggregate and trade-off impacts on animals, but they are not yet applied in practice. In the literature, advances have been made to monetise policy impacts from the animals’ (non-anthropocentric) perspective and to include animals in social welfare functions. Yet, policy analysts who seek to implement any of these approaches in practice face substantial challenges because the available studies differ considerably in the methodologies and underlying normative assumptions. We conduct a critical review of the scientific and grey literature with the aim to synthesise the available material, to facilitate an informed debate on conflicting normative assumptions, and to eventually guide the practical application of non-anthropocentric cost-benefit analysis and social welfare functions. The results of the critical review are presented in the form of a checklist that allows to better comprehend key steps of the methodologies. Step-by-step, the checklist gives an overview of the alternative options and normative assumptions in the literature, and points to any remaining research gaps. Beside the academic debate, this is relevant for practical policy analysts who need to make methodological choices for their policy questions at hand.
Broiler production in Ghana and Senegal : farm economics, international competitiveness and policy considerations
(2023) Chibanda, Craig Chikomborero; Wieck, Christine
Chicken meat consumption has rapidly increased in many West African countries in the last three decades. The increase in consumption has been attributed to several factors, which include population growth, urbanization, rising incomes, and the nutritional importance of chicken meat. However, poultry producers in many West African countries were struggling to meet the rising demand. Consequently, the gap in supply and demand led to an increase in frozen poultry meat imports by many African countries at the end of the 1990s. Most of the imports consisted of chicken meat cuts, which were considerably cheaper than domestically produced chicken meat. Price-wise, domestic chicken meat could not compete with imports, which sparked debate over their importation. In West African nations such as Ghana, Senegal, and Ivory Coast, farm closures, income losses, and a precipitous decline in domestic poultry production are believed to have resulted from the imports' low prices. In the early 2000s, countries in the region reacted differently to the influx of low-priced chicken imports, with some countries instituting protectionist measures that halted the imports while others continued to import the low-priced frozen chicken meat as a means of providing their citizens with a source of affordable animal protein. Although there has been much debate about the various pathways that countries have taken, limited research has been conducted to compare the agronomic and economic status quo of broiler chicken production in countries with different policies. Against this backdrop, the overarching objective of this dissertation is to investigate the economics and international competitiveness of broiler production in two West African countries pursuing different poultry trade policies: Ghana (which is heavily reliant on chicken meat imports) and Senegal (which banned poultry meat imports for almost two decades). Five research gaps in the body of literature on broiler production in Ghana and Senegal are identified in this dissertation. First, existing studies classify broiler production in Ghana and Senegal into broad production systems that are ambiguous. Second, although a number of studies have been conducted on the Ghanaian broiler value chain, there are conflicting arguments regarding the reasons for its lack of development. Third, existing studies do not provide comprehensive analyses of the performance (management), cost structure, and profitability of different broiler farm types in Ghana and Senegal. Fourth, there are no existing studies that compare the international competitiveness of broiler farms in West African countries like Ghana and Senegal with those in key chicken meat exporting countries. Fifth, the current body of literature fails to adequately examine some policy-related concerns. Specifically, little consideration is given to the potential effects of implementing alternative poultry trade policies in Ghana on producers. Based on these research gaps, this dissertation attempts to answer three overarching research questions: i. What is the state of broiler farm economics and broiler value chains in Ghana and Senegal? ii. How does the competitiveness of broiler farms in Ghana and Senegal compare with those in key chicken meat exporting countries in Europe (i.e., Germany and the Netherlands)? iii. What are the potential effects of implementing alternative poultry trade policies in Ghana? As this is a cumulative dissertation, the research questions were addressed in a series of journal articles that are included in this dissertation as chapters 2, 3, 4, 5, and 6. Chapter 2 characterizes and analyses the economics of broiler production systems in Ghana. The typical farm approach is used for this purpose. This approach entails constructing empirically grounded farm data sets that are called “typical farms” through the use of a multi-stakeholder workshop, semi-structured interviews, and focus groups. Three broiler production systems in three regions were identified. They include the large-scale integrated production system (> 20,000 birds/year) in the Ashanti (Kumasi) region, the medium-scale system (5,000–20,000 birds/year) in the Brong-Ahafo (Dormaa) region, and the small-scale commercial system (< 5,000 birds/year) in the Greater Accra region. The Technology Impact Policy Impact Calculations (TIPI-CAL) model was then used to determine the performance, costs of production, and profitability of typical farms. TIPI-CAL is a production and accounting model used for farm economic analysis as it allows a detailed examination of farm-level variables and simulations. The findings presented in Chapter 2 show that the typical small-scale farm is performing the least in comparison to the other farm types in the country in terms of feed conversion ratios (FCR) and Broiler farm economy index (BFEI). The low farm performance of the typical small-scale farm is attributed to the use of poor-quality feed, inappropriate husbandry practices, and its long feeding period. Small-scale producers in Ghana attribute the unusually long feeding period (around 63 days) to market competition from low-priced frozen chicken meat imports. The producers explained that instead of selling their chickens in 42 days they had to rear them for up to 63 days because there is no ready market for them. The findings also show that although the typical medium-scale and large-scale integrated farms are generally performing better than the small-scale farm, they are also not performing so well in terms of the expected performance levels. Furthermore, the results show that broiler production in Ghana is typically seasonal. The seasonal production was attributed to the competition from frozen chicken meat imports, which are cheaper and more readily available in cut pieces, making preparation easier than with domestic chickens that are typically sold live. The results of the farm economic analysis also show that feed and day-old chick (DOC) costs are the most significant production cost items for all three typical farms. Despite the relatively high costs of feed and DOCs, broiler production as a seasonal activity is profitable for all typical farms. Chapter 3 studies the performance of Ghana’s poultry value chain and examines the interlinked challenges that actors in the value chain are facing and their underlying causes. The Sustainable Food Value Chain (SFVC) framework is used to assess and develop strategies to sustainably upgrade the Ghanaian broiler value chain. The SFVC concept moves away from the traditional approach of value chain analysis, where well-known constraints are listed along with proposed recommendations. Instead, the concept takes a universal perspective to identify the interlinked foundational causes of why value chain actors fail to take advantage of existing end-market opportunities. Due to the complex nature of studying value chains, both qualitative and quantitative research methods are employed. These include focus groups, semi-structured interviews, desk reviews, and the Delphi method. The results of the study highlight the poor economic, social, and environmental performance of the Ghanaian poultry sector. Although the results of the Delphi study show that poultry experts in Ghana perceive imports and high feed costs as the most significant challenges facing the value chain, a deeper analysis reveals that weak vertical and horizontal coordination among actors in the value chain, coupled with low commitment from supporting stakeholders, emerge as the root causes of the value chain's challenges. To achieve sustainable growth, the Ghanaian poultry value chain requires commitment and support from the government and other stakeholders, as well as coordination between them. The study also explains that effective vertical relationships (e.g., trust and communication) will play a vital role in the process of upgrading the value chain by promoting conditions that encourage investment. Also, effective cooperation in the horizontal linkages, for example, among producer associations (especially for the many small-scale producers), would contribute to reducing their production costs while facilitating their access to buyers and processors. In addition, competitive improvements would result in more value-added domestic chicken products that cater to the growing demands of Ghanaian consumers at lower prices. Chapter 4 studies the state of broiler production in Senegal after nearly two decades of poultry import restrictions. It provides a synopsis of the Senegalese broiler value chain and evaluates the performance and economics of different farm types. A multi-stakeholder workshop and interviews were conducted with key informants to investigate the structure and activities of the Senegalese broiler value chain. Again, the typical farm approach was used to construct and analyze typical farms that represent the most common broiler production systems in Senegal. Small-scale (<10.000 birds/year), medium scale (10,000–100,000 birds/year), and large-scale integrated (> 100,000 birds/year) production systems were identified as the most prevalent broiler production systems. The findings show that the two typical medium-scale broiler farms in Senegal are performing well in terms of FCRs, BFEI, and mortality rates. The good performance is attributed to the use of high-quality inputs (feed and chicks) and good husbandry practices. The results of the value chain analysis suggest that the country has well-developed feed and hatchery industries. Therefore, the development of these industries has ensured that producers have access to domestically produced, high-quality inputs. Nevertheless, the typical small-scale farm is not performing well, and this is attributed to inappropriate poultry husbandry practices. Additionally, the analysis revealed that feed and day-old chick (DOC) costs are the most significant in conventional broiler production in Senegal. Despite the high costs of feed and DOCs, broiler production is profitable for all typical farms. Chapter 5 examines whether differences in the competitiveness of broiler farms in Ghana, Senegal, Germany, and the Netherlands provide insight into why domestically produced chicken meat in West African countries is more expensive than imports from Europe. For this comparison, farm management (none monetary farm performance indicators) and economic performance indicators (costs of production and profitability) of typical broiler farms in the four countries are derived. The study shows that most of the typical broiler farms in Ghana and Senegal are not competitive with farms in Germany and the Netherlands in terms of farm management. More specifically, the findings show that the typical German and Dutch broiler farms are performing better than all typical farms in Ghana and the typical small-scale farm in Senegal in terms of the FCRs, BFEI, mortality rates, and number of production cycles per year. However, the performance of typical medium scale farms in Senegal is almost comparable to that of German and Dutch farms in terms of all the farm management indicators that were analyzed. The good farm management of medium scale farms in Senegal is attributed to good animal husbandry practices and the use of high-quality feed and high-quality DOCs. The findings also show that typical broiler farms in Ghana and Senegal are not competitive with German and Dutch farms in terms of economic performance. The poor economic performance of the Ghanaian and Senegalese farms is attributed to higher production costs. Apparently, the broiler farms in the two countries have higher production costs due to high feed and DOC costs. In Ghana, high feed costs are attributed to high feed prices and feed-use inefficiency (reflected by high FCRs). In the case of Senegal, high feed costs are largely due to high feed prices. Having established that typical broiler farms in Ghana and Senegal are not competitive in terms of farm management and costs of production , the impact of improving farm management (primarily the FCRs) on production costs was then simulated using the TIPI-CAL model. The results of the simulations demonstrate that improving farm management to optimum levels would lead to a reduction in the costs of production for Ghanaian and Senegalese farms. However, the reduction would not be sufficient to make the farms competitive with those in Germany and the Netherlands because high input costs (feed and DOC) are the primary contributors to high production costs. Improving the competitiveness of broiler farms will therefore require a combination of interventions designed to lower input costs and enhance farm management. For decades, Ghanaian policymakers have been pressured to implement protectionist policies to protect the poultry value chain from low-priced imports. Chapter 6 examines the potential impact of implementing these policies. The Modular Applied General Equilibrium Tool (MAGNET) and TIPI-CAL models are used to examine the: (1) potential impact of a hypothetical complete ban of poultry meat imports in Ghana; (2) potential impact of a partial ban of poultry products (banning poultry products originating from the UK, Germany, the Netherlands, Denmark, and Russia); (3) potential effects of raising the import tariffs on poultry meat in Ghana to 40 percent and 99 percent; and (4) potential effects of abolishing the current 5% import tariff rate on maize imports. The results show that a complete ban on poultry meat imports would have a positive impact on domestic poultry meat production, increasing production by 254%. This increase will be most likely driven by existing farms doubling their production cycles and new producers attracted to a protected broiler sector. The findings also show that a complete ban would increase the importation of maize. Considering the importance of maize for poultry production in Ghana, the effects of abolishing the existing 5% import tariff rate on maize were simulated. The results show that removing the tariff would not lead to a significant increase in poultry production. This is most likely due to the fact that the tariff rate is already very low. In accordance with World Trade Organization (WTO) agreements, Ghana is allowed to increase the tariff rate on poultry meat up to 99% (the maximum level of bound tariff). The findings show that increasing the tariff rate from the current 35% to 99% would result in a 104% increase in domestic poultry meat production. The tariff would offer significant protection to domestic producers and result in a significant reduction in poultry meat imports (around 57% reduction in imports). The typical farm analysis indicates that broiler farms in Ghana are more prevalent in urban and peri-urban areas. Therefore, a boost in domestic poultry meat production would most likely lead to an increase in urban and peri-urban employment. The findings also show that medium- and large-scale farms employ the highest number of people; therefore, such farm types are expected to boost urban and peri-urban employment if they increase production. Also, of importance, an increase in domestic broiler production will most likely have positive knock-on effects on other value chain actors such as slaughterhouses, feed millers, and poultry traders. Although the results indicate that producers will benefit from the implementation of protectionist measures, it is important for policymakers to keep in mind that such measures will most likely also have negative implications. For example, the results show that protectionist measures would lead to a decrease in the Gross domestic product (GDP) as the measures would either reduce or eliminate the imports leading to reduced tariff revenues, which account for a large share of total tariff revenues in Ghana. The dissertation concludes that a comprehensive sector-wide policy-making approach that considers all the challenges facing the different value chain actors (e.g., hatcheries, feed millers, producers, traders, slaughterhouses and consumers) will be more effective in providing a delicate balance that ensures that the broiler value chains in Ghana and Senegal develop and consumers have access to affordable chicken meat. Such an approach would also be useful in addressing the issue of high input prices (mainly feed and day-old chicks), which is at the center of the low competitiveness of broiler farms in the two countries. Additionally, the comprehensive policy-making approach should also consider the need for proper infrastructure and technology to support the growth of broiler value chains. This includes investments in cold storage facilities and slaughterhouses to ensure efficient and cost-effective processing and distribution of chicken meat. By addressing these challenges holistically, policymakers can create an enabling environment for the development of sustainable and competitive broiler value chains in both countries.
Cartographie du commerce agricole au sein de la CEDEAO : structure et flux des produits agricoles, obstacles au commerce, lacunes en matière de financement et options politiques. Un projet de recherche en coopération avec la GIZ pour le compte du BMZ

This study reviews the structure and flow of formal and informal agri-food trade within ECOWAS and evaluate the trade barriers, financial and quality infrastructure gaps. A mixed-method approach – qualitative and quantitative methods – is adopted which comprises an extensive literature review, analysis of available statistical data on formal and informal trade and trade barriers, a field survey, expert interviews and workshops. The intra-ECOWAS agri-food trade is still at the low level with most of the traded agri-food commodities largely without value addition and characterised by inadequate diversification of the export base. A preponderance of informal agri-food trade along both the formal and informal trade corridors are detected. Livestock, oilseeds, cottonseed, nuts, cocoa beans, cereal, cassava, fisheries, fruits and vegetables were the most traded agri-food commodities, which were not given any concession of passage or facilitated across the borders despite the perishability of the commodities. Agri-food trade flows in the ECOWAS are largely hampered by the heterogeneous trade policy measures across the Member states. This is often a barrier to trade and tend to increase trade costs and commodities prices, thereby constraining the regional trade benefits to the people while also making the trading countries uncompetitive. Women agri-food traders were often exploited and harassed by the different borders’ officials. More so, the low intra-ECOWAS trade in agricultural and food products is due to the low production capacities, which among others are due to the inadequate finance, poor quality infrastructure – soft (trained inspectors, customs procedures digitalisation, certification, etc) and hard (metrology facilities, roads, ports’ facilities, testing and inspection laboratories, etc.). Agricultural trade finance has been identified as one of the key challenges inhibiting trade in agricultural commodities in this subregion. Strategic policy options to promote agri-food trade within ECOWAS are provided

Navigating the indicator jungle: A roadmap to analyze common agricultural policy indicators
(2024-09-01) Gorn, Anne-Kartrin; Barissoul, Ayoub; Wieck, Christine
The CAP monitoring framework includes a wide range of policy indicators, covering output, results, context, and impact. In environmental policy sciences, the complexities of analysing policy instruments and indicators are well known and techniques like statistical pattern analysis and grouping indicators into "umbrella" or composite indicators are recommended to simplify analysis. These methods are less common in agricultural economics and political sciences. This working paper investigates methods for constructing umbrella indicators and presents a literature-based roadmap for their application to the CAP indicators. It demonstrates that these methods can be successfully applied not only in other scientific fields but also to CAP indicators.
