Field Surveys

Despite notable progress in reducing global poverty and hunger in recent decades, about one out of nine people in the world suffers from hunger and malnutrition. Stakeholders charged with making decisions pertaining to agricultural production, development priorities, and policies at a region-to-country scale require quantitative and up-to-date information on the types of crops being cultivated, the acreage under cultivation, and crop yields. However, many low- and middle-income countries lack the infrastructure and resources for frequent and extensive agricultural field surveys to obtain this information. Technology supports a change of paradigm. Traditional methods of obtaining agricultural information through field surveys are increasingly being augmented by images of the Earth acquired through sensors placed on satellites. The continued improvement in the resolution of satellite images, the establishment of open-access infrastructure for processing of the images, and the recent revolutionary progress in artificial intelligence make it feasible to obtain the information at low cost and in near-to-real time. In this brief, we discuss the use of satellite images to provide information about agricultural production in low-income countries, and we comment on research challenges and opportunities. We highlight the near-term potential of the methodology in the context of Rwanda, a country in sub-Saharan Africa whose government has recognized early the value of information technology in its strategic planning for food security and sustainability.

Policy Guidance

Having broadly stabilized inflation over the past two decades, many policymakers in sub-Saharan Africa are now asking more of their monetary policy frameworks. They are looking to avoid policy misalignments and respond appropriately to both domestic and external shocks, including swings in fiscal policy and spikes in food and export prices. In many cases they are finding current regimes—often characterized as ‘money targeting’—lacking, with opaque and sometimes inconsistent objectives, inadequate transmission of policy to the economy, and difficulties in responding to supply shocks. At the same time, little existing research on monetary policy is targeted to low-income countries. What do we know about the empirics of monetary transmission in low-income countries? (How) Does monetary policy work in countries characterized by a huge share of food in consumption, underdeveloped financial markets, and opaque policy regimes? (How) Can we use methods largely derived in advanced countries to answer these questions? And (how) can we use the results to guide policymakers? This book draws on years of research and practice at the IMF and in central banks from the region to shed empirical and theoretical light on these questions and to provide practical tools and policy guidance. A key feature of the book is the application of dynamic general equilibrium models, suitably adapted to reflect key features of low-income countries, for the analysis of monetary policy in sub-Saharan African countries.

Abstract Background Coronavirus disease (COVID-19) is a severe acute respiratory infection which has afflicted virtually almost all nations of the earth. It is highly transmissible and represents one of the most serious pandemics in recent times, with the capacity to overwhelm any healthcare system and cause morbidity and fatality. Main content The diagnosis of this disease is daunting and challenging as it is dependent on emerging clinical symptomatology that continues to increase and change very rapidly. The definitive test is the very expensive and scarce polymerase chain reaction (PCR) viral identification technique. The management has remained largely supportive and empirical, as there are no officially approved therapeutic agents, vaccines or antiviral medications for the management of the disease. Severe cases often require intensive care facilities and personnel. Yet there is paucity of facilities including the personnel required for diagnosis and treatment of COVID-19 in sub-Saharan Africa (SSA). It is against this backdrop that a review of key published reports on the pandemic in SSA and globally is made, as understanding the natural history of a disease and the documented responses to diagnosis and management is usually a key public health strategy for designing and improving as appropriate, relevant interventions. Lead findings were that responses by most nations of SSA were adhoc, paucity of public health awareness strategies and absence of legislations that would help enforce preventive measures, as well as limited facilities (including personal protective equipment) and institutional capacities to deliver needed interventions. Conclusion COVID-19 is real and has overwhelmed global health care system especially low-income countries of the sub-Sahara such as Nigeria. Suggestions for improvement of healthcare policies and programs to contain the current pandemic and to respond more optimally in case of future pandemics are made herein.

Methodical Approach

The paper deals with weather derivatives as the potentially effective risk management tool for agricultural enterprises seeking to mitigate their income exposure to variations in weather conditions. Design and valuation of the weather derivatives is an interdisciplinary approach covering agrometeorology, statistics, mathematical modeling, and financial and risk management. This paper first offers an overview of data sources and then methods of design and valuation of weather derivatives at the regional level. The accompanied case study focuses on cultivation of cereals (wheat and barley) in the Czech Republic. However, its generalizability is straightforward. The analysis of key growing phases of cereals is based on regression analysis using weather indices as the independent variables and crop yields as dependent variables. With the bootstrap tool, the burn analysis is considered as useful tool for estimating uncertainty about the payoff, option price, and statistics of probability distribution of revenues. The results show that the spatial and production basis risks reduce the efficiency of the weather derivatives. Finally, the potential for expansion of weather derivatives remains in the low income countries of Africa and Asia with systemic weather risk.

The Impact

Purpose This paper aims to investigate the long-run impact of selected foreign capital inflows, including aid, remittances, foreign direct investment (FDI), trade and debt, on the economic growth of 21 low-income countries in the Sub Saharan Africa (SSA) region, during the period 1990–2018. Design/methodology/approach To obtain this objective and for robust analysis, a parametric approach, which was dynamic ordinary least squares, and a non-parametric technique, which was fully modified ordinary least squares, were used. Findings The results of both models confirmed that, in the long run, trade and aid affected the growth rate of the per capita income in these countries in a positive way. However, external debt seemed to have an adverse influence on such growth. Originality/value First, this is the initial study that has addressed this matter across a homogenous group of countries in the SSA region. Second, while most of the previous studies regarding capital inflows into the SSA region have focused on the impact of only one or two aspects of such foreign capital inflows on growth, the present study, instead, examined the impact of five types of foreign capital inflows (aid, remittances, FDI, trade and debt).

Climate change is posing a threat on present and future food security in low income countries. But, the actual effect of the climate change on food security is not known. Using secondary data reported by the government, the paper examines the effects of climate change on food security in Nepal in the context of policies of commercialization of farm production. Statistical analysis is used to delineate the situation of food security in the country and regression analysis for exploring the effects of global warming on domestic production of major cereals. The results are discussed at global, national, household and individual levels empirically and qualitatively. The results suggest that a rise in minimum temperature decreases the productivity of rice increasing threat of food insecurity. The paper suggests some policy measures for improving food security situation in the country and open up some areas for further research.

Introduction Recent debates surrounding the lagging covid-19 vaccination campaigns in low-income countries center around vaccine supply and financing. Yet, relatively little is known about attitudes towards covid-19 vaccines in these countries and in Africa in particular. In this paper, we provide cross-country comparable estimates of the willingness to accept a covid-19 vaccine in six Sub-Saharan African countries. Methods We use data from six national high-frequency phone surveys from countries representing 38% of the Sub-Saharan African population (Burkina Faso, Ethiopia, Malawi, Mali, Nigeria, and Uganda). Samples are drawn from large, nationally representative sampling frames providing a rich set of demographic and socio-economic characteristics by which we disaggregate our analysis. Using a set of re-calibrated survey weights, our analysis adjusts for the selection biases common in remote surveys. Results Acceptance rates in the six Sub-Saharan African countries studied are generally high, with at least four in five people willing to be vaccinated in all but one country. Vaccine acceptance ranges from nearly universal in Ethiopia (97.9%, 97.2% to 98.6%) to below what would likely be required for herd immunity in Mali (64.5%, 61.3% to 67.8%). We find little evidence for systematic differences in vaccine hesitancy by sex or age but some clusters of hesitancy in urban areas, among the better educated, and in richer households. Safety concerns about the vaccine in general and its side effects emerge as the primary reservations toward a covid-19 vaccine across countries. Conclusions Our findings suggest that limited supply, not inadequate demand, likely presents the key bottleneck to reaching high covid-19 vaccine coverage in Sub-Saharan Africa. To turn intent into effective demand, targeted communication campaigns bolstering confidence in the safety of approved vaccines and reducing concerns about side effects will be crucial to safeguard the swift progression of vaccine rollout in one of the world's poorest regions.

Diarrhea is the second leading cause of death and is the major cause of malnutrition in children under age 5 worldwide. More than 50 percent of the cases occur in developing countries, particularly in sub-Saharan Africa and Southeast Asia. Open defecation, substandard fecal disposal systems, and contaminated water supplies are the typical causes of diarrheal diseases. This public health crisis in low income countries mirrors the experiences of today's industrialized nations two centuries ago. The lessons learned from their sanitary evolution can be instructive in charting a sustainable path towards saving the lives of almost 2 million children annually. In this chapter a case study of Cuba's sanitary reformation is also presented to showcase successes, similar to those of developed countries, within a developing country and economically challenging context.

Abstract Background High Blood Pressure is the worldwide leading global burden of disease risk factor. In Sub-Saharan Africa, the number of adults with raised blood pressure has alarmingly increased from 0.59 to 1.13 billion between 1975 and 2015. Blood pressure-lowering medicines are cornerstone of cardiovascular risk reduction. Data on management of anti-hypertensive drugs in sub-Saharan Africa are squarce. Purpose Our study aims to describe antihypertensive drugs strategies in Africa. Methods We conducted a cross-sectional survey in urban clinics during outpatient consultation specialized in hypertension cardiology departments of 29 medical centers from 17 cities across 12 African countries (Benin, Cameroon, Congo, Democratic Republic of Congo, Gabon, Guinea, Ivory Coast, Mauritania, Mozambic, Niger, Senegal, Togo). Data were collected on demographics, treatment and standardized BP measures were made among the hypertensive patients attending the clinics. Country income was retrieved from the World Bank database. All analyses were performed through scripts developed in the R software (3.4.1 (2017–06–30)). Results A total of 2198 hypertensive patients (58.4±11.8 years; 39.9% male) were included. Among whom 2123 (96.6%) had at least one antihypertensive drug. Overall, 30.8% (n=653) received monotherapy and calcium-channel blockers (49.6%) were the most common monotherapy prescribed follow by diuretics (18.7%). Two-drug strategies were prescribed for 927 patients (43.6%). Diuretics and Angiotensin-converting enzyme inhibitors was the combination most frequently prescribed (33.7%). Combination of three drugs or more was used in 25.6% (n=543) of patients. The proportion of drugs strategies differed significantly according to countries (p<0.001), monotherapy ranged from 12.7% in Niger to 47.1% in Democratic Republic of the Congo (figure). Furthermore we observed a significantly difference of strategies between low and middle income countries (55.3% and 44.7% of monotherapy respectively) (p<0.001). According to hypertension grades 1, 2 and 3, the proportion of three-drugs or more combination was 25%, 28% and 34% in middle-income and lower in low-income countries (18%, 19% and 25%). Furthermore, Grade 3 hypertension in low income countries was still treated with monotherapy (36%) instead of 19% in middle income countries (p<0.01). Antihypertensive strategies by country Conclusion Our study described antihypertensive drugs use across 12 sub-Saharan countries, and identified disparities specific to the income context. Inequity in access to drugs combination is a serious barrier to tackle the burden of hypertension in Africa.
