The purpose of this study is to examine the relative importance of climate normals (average long-term temperature and precipitation) in explaining net farm revenue per hectare (NRh) for supplementary irrigated and rainfed cocoa farms in Nigeria.

NRh was estimated for 280 cocoa farmers sampled across seven Nigerian states. It was regressed on climate, household socio-economic characteristics and other control variables by using a Ricardian analytical framework. Marginal calculations were used to isolate the effects of climate change (CC) on cocoa farm revenues under supplementary irrigated and rainfed conditions. Future impacts of CC were simulated using Six CORDEX regional climate model (RCM) ensemble between 2036-2065 and 2071-2100.

Results indicate high sensitivity of NRh to Nigerian climate normals depending on whether farms use supplementary irrigation. Average annual temperature increases and precipitation decreases are associated with NRh losses for rainfed farms and gains for supplementary irrigated cocoa farms. Projections of future CC impacts suggest a wide range of NRh outcomes on supplementary irrigated and rainfed farm revenues, demonstrating the importance of irrigation as an effective adaptation strategy in Nigeria.

This paper uses novel data sets for simulating future CC impacts on land values in Nigeria. CORDEX data constitute the most comprehensive RCMs projections available for Africa.

The purpose of this paper is to compare the assessment of poverty/deprivation using different conceptions of this phenomenon including the traditional money‐metric measure and different forms of multidimensional constructs.

The data were drawn from a household survey conducted in Nsukka, Nigeria. Interviewer‐administered questionnaires were used in data collection from about 410 households across urban and rural localities. The counting and FGT methodologies were used to assess impoverishment, while regression analyses were used to assess the determinants of deprivation across different constructs.

Between 70 per cent and 78 per cent of the study population were identified as poor/deprived. However, more than 11 per cent of those living on less than USD1.25/day were classified as non‐poor using different measures of multidimensional poverty. Similarly, more than 62 per cent of individuals who live on more than 1.25USD/day (i.e. non‐poor) are classified as poor using different measures of multidimensional deprivation. There is some level of correlation between measures, some inevitably stronger than others. The major determinants of deprivation across the various constructs of deprivation include large family size, low level of education, poor employment, rural location, and poor health.

This paper uses novel datasets that incorporate variables relating to the capability approach in understanding deprivation. Specifically, it analyses the so‐called missing dimensions of poverty. It also applies a new methodology for the assessment of impoverishment and deprivation. It highlights the importance of the capability approach in explaining poverty.

The subsidization of artemisinin combination therapy (ACT) at supranational level to avoid undermining the private distribution system in sub‐Saharan Africa and elsewhere, as advocated by Committee on the Economics of Antimalarial Drugs board on Global Health, requires the appraisal of the economic behaviour of relevant private agents in these regions, in order to assess their potential influence on access to ACT. The purpose of this paper is to analyze the economic behaviour of informal medicine retailers and how this effects access to ACT, using data generated from a primary survey in southeast Nigeria.

A field survey was carried out which included health providers and households. A market price survey was undertaken to generate primary data, using closed and semi‐open questionnaires, and there were focus group discussions in two south‐eastern states in Nigeria. A standard two‐stage method was used for the design of the survey.

The study demonstrates that the economic behaviour of informal medicine affects market prices of ACT, facilitates information diffusion, improves availability and acceptability dimensions of access to ACT. However, their clinical practices are weak and require policy interventions.

This paper brings to the fore the influence of economic behaviour of retail agents in the medical market, which needs to be taken into account when considering alternative distributional channels for ACT, if the WHO goal of universal access in malaria‐endemic regions is to be achieved.
