Adoption and impact of an award winning post-harvest technology: The ASI rice thresher in the Senegal River Valley AgEcon
Diagne, Mandiaye; Demont, Matty; Diagne, Aliou.
In Senegal, one of the highest rice import-dependent countries in Sub-Saharian Africa, double cropping is recommended in the new national program for the Great Offensive for Food and Abundance (GOANA) to boost rice production. This target impels the respect of cropping calendar by using improved technologies like the ASI thresher-cleaner. The causal or treatment effect framework (ATE and LATE) is used to estimate the ASI adoption rate and impact. The results show that the true ASI adoption rate would be 86 % if all the population of irrigated rice farmers were exposed to it. The socioeconomic characteristics that increase the probability to adopt the ASI thresher are farmer experience, farm size, and participation to ASI field experiments and/or contact...

Agricultural trade for food security in Africa: A Ricardian model approach AgEcon
Diagne, Mandiaye; Abele, Steffen; Diagne, Aliou; Seck, Papa Abdoulaye.
Regionalism and food security is a relatively neglected topic with very limited literature. We use a Ricardian trade model with multiple goods and countries which embeds a structure of gravity equation and yield variability. Our study shows that integration with African markets of staple foods is associated with higher growth, underpinning the need for growth strategies to emphasize scaling up and diversifying exports within Africa. Africa needs to unlock its high potential untapped land and fill up the yield gap. We found as well that enhanced competitiveness and reduced barriers to trade are the two critical areas of action.

Compétitivité de la filière riz local au Togo: Une évaluation du taux de protection nominale, effective et du coût en ressource domestique AgEcon
Tabone, Kperim; Koffi-Tessio, Egnonto M.; Diagne, Aliou.
The purpose of this study is to analyze the factors which influence the competitiveness of local rice in Togo in order to contribute to a better formulation of a rice policy. This analysis was done by a characterization of the actual situation of the local production and by the evaluation of the incentives of the state pricing policy as well as the production’s competitiveness. The approach of the Policy Analysis Matrix (MAP) or reference price was used. The analysis of the results shows, on the one hand, that the production of local rice in Togo exhibits a comparative advantage compared to imported rice and, on the other hand, that the public interventions favour the local production. Indeed, the local production benefits from an implicit protection...

DEMANDE DU RIZ IMPORTE, DEMANDE DU RIZ PRODUIT LOCALEMENT AU TOGO : UNE ESTIMATION À PARTIR DU MODÈLE ALMOST IDEAL DEMAND SYSTEM (AIDS) AgEcon
Tchabletienne, Kombate; Koffi-Tessio, Egnonto M.; Diagne, Aliou.
L’approximation linéaire du modèle Almost Ideal Demand System (LA/AIDS) est utilisée pour estimer la demande du riz (riz local et riz importé) au Togo de 1986 à 2006. Un modèle à correction d’erreur (MCE) a été développé pour tenir compte des relations de court terme entre les variables. Les paramètres de court et de long terme ont été estimés par les MCO. Dans cette étude, le riz local et le riz importé sont supposés être faiblement séparables des autres biens. Cette hypothèse excluant les relations avérées entre le riz importé et le riz local d’une part et entre ces produits, et les autres produits alimentaires d’autre part ; a conduit à estimer la demande du riz au Togo au deuxième stade d’un processus de maximisation de l’utilité. Les paramètres de...

Determinants of Agricultural Technology adoption: the case of improved groundnut varieties in Malawi AgEcon
Simtowe, Franklin; Asfaw, Solomon; Diagne, Aliou; Shiferaw, Bekele A..
This paper applies the Average Treatment Effect (ATE) framework on data obtained from a random cross-section sample of 594 farmers in Malawi to document the actual and potential adoption rates of improved groundnut varieties and their determinants conditional on farmers’ awareness of the technology. The fact that not all farmers are exposed to the new technologies makes it difficult to obtain consistent estimates of population adoption rates and their determinants using direct sample estimates and classical adoption models such as probit or tobit. Our approach tries to control for exposure and selection bias in assessing the adoption rate of technology and its determinants. Results indicate that only 26% of the sampled farmers grew at least one of the...

DETERMINANTS OF HOUSEHOLD ACCESS TO AND PARTICIPATION IN FORMAL AND INFORMAL CREDIT MARKETS IN MALAWI AgEcon
Diagne, Aliou.
The paper uses the concept of credit limit to analyze the determinants of household access to and participation in informal and formal credit markets in Malawi. Households are found to be credit constrained, on average, both in the formal and informal sectors; they borrow, on average, less than half of any increase in their credit lines. Furthermore, they are not discouraged in their participation and borrowing decisions by further increases in the formal interest rate and/or the transaction costs associated with getting formal credit. This suggests that getting access to credit is much more important than its cost for these households. Hence, credit policies should focus on making access easier rather than providing credit with subsidized interest rates....

EMPIRICAL MEASUREMENTS OF HOUSEHOLDS' ACCESS TO CREDIT AND CREDIT CONSTRAINTS IN DEVELOPING COUNTRIES: METHODOLOGICAL ISSUES AND EVIDENCE AgEcon
Diagne, Aliou; Zeller, Manfred; Sharma, Manohar P..
This paper presents a new methodological framework for measuring the level of household access to credit. It provides an analytical framework for examining the determinants of household credit limits and derives implications on information needed to examine the extent to which households are credit constrained. Empirical application of this method involves directly eliciting credit limit information in household surveys. Illustrations are provided using data from Bangladesh and Malawi.

Estimation of Actual and potential adoption rates and determinants of a new technology not universally known in the population: The case of NERICA rice varieties in Guinea AgEcon
Diagne, Aliou; Sogbossi, Marie-Josee; Simtowe, Franklin; Diawara, Sekou; Diallo, Abdoulaye Sadio; Barry, Alpha Bacar.
The NERICA (New Rice for Africa) rice varieties, developed by the Africa Rice Center during the 1990s, are providing hopes for raising the productivity of upland rice farmers in Africa because of their reported high yield potential and adaptability to the African conditions. The varieties are new and not widely disseminated in farming communities and there is lot of interest in the donor community in knowing their potential for widespread adoption across sub-Saharan Africa (SSA). However, when a technology is new and the target population is not universally exposed it, the observed sample adoption rate and classical models of adoption widely used in adoption studies does not inform reliably on its potential adoption and constraint to it in the full...

Estimation of Actual and Potential Adoption Rates and Determinants of Improved Rice Variety Among Rice Farmers in Nigeria: The Case of NERICAs AgEcon
Dontsop Nguezet, Paul Martin; Diagne, Aliou; Okoruwa, Victor O..
The article used the ATE estimation framework to derive consistent semi-parametric estimators of population adoption rates and their determinants of the NERICA (New Rice for Africa) rice varieties in Nigeria. Empirical evidence shows that the observed sample adoption rate does not consistently estimate the population adoption rate even if the sample is random. NERICA awareness was found to be a major constraint to NERICA adoption in Nigeria. Several socioeconomic/demographic characteristics were found to be important determinants of NERICA awareness and adoption. Among those factors are age, gender, major occupation, year of experience and vocational training. In particular, we have found that the NERICA adoption rate in Nigeria would have been up to 76%...

Evaluation de la diffusion et de l’adoption des variétés de riz NERICA en Guinée AgEcon
Diagne, Aliou; Sogbossi, Marie-Josee; Diawara, Sekou; Diallo, Abdoulaye Sadio; Barry, Alpha Bacar.
L’objectif de la présente étude est d’évaluer la diffusion et l’adoption des variétés de riz NERICA en Guinée cinq années après leur introduction. Les données collectées en 2002 sont relatives à 1535 paysans choisis dans 79 villages des quatre régions naturelles de la Guinée. L’approche d’estimation du taux d’adoption utilisée dans ce papier se fonde sur les théories modernes d’évaluation au niveau micro-économique des impacts d’interventions politiques. Nos résultats montrent que 39% de la population guinéenne connaissaient au moins une variété NERICA en 2001 avec 23% pour le taux d’adoption observé au sein de la population de riziculteurs. Plusieurs facteurs socio-économiques déterminent les taux de diffusion et d’adoption. Par ailleurs bien que le...

Gendered Impact of Irrigated Rice Schemes’ Governance on Farmers’ Income, Productivity and Technical Efficiency in Benin AgEcon
Kinkingninhoun-Medagbe, Florent M.; Diagne, Aliou; Agboh-Noameshie, Afiavi R.; Adegbola, Patrice Ygue.
Collective actions groups have many advantages and are sometimes essential, yet they can reinforce or perpetuate inter-and intra-gender inequalities when their functioning is left entirely subject to internal community dynamics and they are not well managed. This is well illustrated by the case of Koussin-Lélé rice scheme in the central Benin. This paper apply inequality indices and frontier production function to data from a sample of male and women rice farmers to analyze the gender inequalities in access to land and the governance of the groups, and their gender-differentiated impacts on farmers' productivity, technical efficiency and income. The results show that women are particularly discriminated against with regards to access to land, with...

Gendered impact of NERICA Adoption on Farmers’ Production and Income in Central Benin AgEcon
Agboh-Noameshie, Afiavi R.; Kinkingninhoun-Medagbe, Florent M.; Diagne, Aliou.
Today, development and dissemination of new technologies constitute an important strategy for agricultural intensification, poverty reduction and food security in developing countries. Rice is an important source of farmers’ income and foreign currencies in developing countries. Although women play a vital role in rice production, they have not been adequately involved in technology generation activities until recently. The New Rices for Africa (NERICA) were developed by Africa Rice Center (WARDA) in 1994 and disseminated starting in 1997 in some Sub-Saharan African countries including Benin in collaboration with National Agricultural Partners. This paper use econometric method based on Local Average Treatment effect (LATE) to estimate the gendered impact...

IMPACT OF ACCESS TO CREDIT ON INCOME AND FOOD SECURITY IN MALAWI AgEcon
Diagne, Aliou.
The paper departs from the standard practice that takes the estimated marginal effects of either the amount of credit received or membership in a credit program as measures of the impact of access to credit on household welfare. The marginal effects of the formal credit limit variable on household welfare, controlling for the credit limit from informal sources as well as the credit demanded from both sources, measure the marginal effects of access to formal credit. The main finding of the paper is that access to formal credit, by enabling households to reduce their borrowing from informal sources, has marginally beneficial effects on household annual income. However, these effects are very small and do not cause any significant difference between the per...

Market Access by Smallholder Farmers in Malawi: Implications for Technology Adoption, Agricultural Productivity, and Crop Income AgEcon
Zeller, Manfred; Diagne, Aliou; Mataya, Charles.
In Malawi, maize is the major crop and food staple. Given limited off-farm employment opportunities, much-needed increases in household income for improving food security must come from gains in agricultural productivity through better technology and more profitable crops. In the past, agricultural policy promoted hybrid maize and, more recently, tobacco to increase smallholder income. This paper presents an analysis of what determines the adoption of these two crops and what kind of income effects follow from adoption. Apart from factor endowment and exposure to agroecological risks, differences in the household's access to financial and commodity markets significantly influence its cropping shares and farm income.

Policy and Institutional effects on market participation by smallholder rice farmers: case studies in Burkina Faso, Mali and Niger AgEcon
Toure, Ali; Bamba, Ibrahim; Diagne, Aliou; Harouna, Kore; Cisse, Youssouf; Kabore, Daniel.
Rice sector contributes significantly to secure households with regard to their food needs but also to the creation of employments and income generation. The sector development and its evolution over the years have been marked by various policies and approaches. These development stages of the sector constitute nothing but the impact of the number of factors such as the rice policies put in place. A collaborative multi-country pilot study on policy and institutional arrangements effects on irrigated rice production and commercialization was conducted by WARDA and its country partners of Burkina Faso, Mali, and Niger. In-depth surveys were carried out at both village and household levels to collect qualitative and quantitative data on irrigated rice...

PROFIL DE PAUVRETE ET FILETS DE SECURITE DES RIZICULTEURS DANS LES ZONES D’INTRODUCTION DES NERICA AU TOGO: cas des régions du nord-Togo AgEcon
Gnatoulouma, Takpa; Koffi-Tessio, Egnonto M.; Diagne, Aliou.
La présente étude a pour objectif une évaluation de l’état de pauvreté des riziculteurs du nord-Togo dans les zones d’introduction des NERICA en vue d’apprécier leurs capacités de résistance aux risques naturels et économiques. Pour parvenir à cette fin, des données primaires collectées sur la base d’une enquête effectuée auprès de 255 ménages dans 20 villages dans les régions centrale et de la Kara, ont été analysées par la méthode de FOSTER GREER et THORBECKE basée sur les dépenses de consommation. L’incidence, la profondeur et la sévérité, sont respectivement de 88,37%, 31% et 12,98%. Le niveau de pauvreté est pratiquement le même aussi bien chez les producteurs de NERICA que les producteurs des variétés. The present study’s objective is an evaluation...
