Mulubrhan Amare, Solomon Asfawb, Bekele Shiferaw This article examines the driving forces behind farmers’ decisions to adopt improved pigeonpea and maize and estimates the causal impact of technology adoption on household welfare using data obtained from a random cross-section sample of 613 small-scale farmers in Tanzania. We use seemingly unrelated and recursive bivariate probit regressions to test the endogeneity and joint decision making of pigeonpea–maize production. A double hurdle model is used to analyze the determinants of the intensity of technology adoption conditional on overcoming seed access constraints. To address the impact of adoption on welfare, the article employs both propensity score matching and switching regression techniques. Results from bivariate probit models show that unobservable factors cause both decisions to be correlated but the finding does not support the conjecture that both decisions are made jointly. Overall the analysis of the determinants of adoption identifies inadequate local supply of seed, access to information, human capital, and access to private productive asset as key constraints for pigeonpea technology adoption. The causal impact estimation from both the propensity score matching and switching regression suggests that maize/pigeonpea adoption has a positive and significant impact on income and consumption expenditure among sample households.

The Global Forum on Food Security and Nutrition (FSN Forum) organized a seminar on a recently published book entitled: How to end hunger in times of crises. Let's start now! We invited FSN Forum members in Rome and interested FAO staff to join a discussion with the two authors, Andrew MacMillan and Ignacio Trueba.
The course provides an overview of Social Safety Net programmes and systems and how they are used and customized according to different contexts. It also introduces the key processes for designing and implementing Social Safety Net programmes

The rationale for these FAO guidelines is to provide a standardized questionnaire of universal applicability from which various dietary diversity scores can be calculated. As such it is not culture, population, or location specific and therefore, prior to using it in the field, it will be necessary to adapt it to the local context. This is a revised version of the guidelines for measuring dietary diversity. The main changes in this version are i) the proposal for a new individual dietary diversity score based on results of the Women’s Dietary Diversity Project (Arimond et al., 2010) and ii) an annex on classifying food items into food groups. Guidance is provided on how to calculate the HDDS and the Women’s Dietary Diversity Score (WDDS), but users can also calculate scores obtained from the standardized questionnaire for individuals from other age/sex groups according to the needs of the study. The guidelines describe how to adapt and use the dietary diversity questionnaire, how to calculate each of the scores and how to create other indicators of interest from dietary diversity data.
