The purpose of this paper is to show how climatic change in Africa is expected to lead to a higher occurrence of severe droughts in semiarid and arid ecosystems. Understanding how crop productions react to such events is, thus, crucial for addressing future challenges for food security and poverty alleviation.

The authors explored how temperature and rainfall patterns determined maize and beans production in Hai District in Kilimanjaro Region, Tanzania.

Annual food crops were particularly sensitive to the drought and maize and beans yields were lower than perennial crops during the years of drought. The authors also report strong and significant association between maize and beans production with temperature and rainfall patterns.

This study highlights how severe droughts can dramatically affect yields of annual crops and suggests that extreme climatic events might act as a major factor affecting agriculture production and food security, delaying or preventing the realization of the Millennium Development Goals.

This is the first study that highlights how severe droughts can dramatically affect yields of annual crops in Hai District contributing to other climate studies done elsewhere in Tanzania and the world at large.

This study seeks to investigate the comparative effects of local and imported coagulants on tofu yield and quality.

Soymilk was extracted from soybean variety, TGX‐923‐24 using cold water extraction method. The milk extract was coagulated to tofu using fermented maize liquor (FML), Alum solution (AS), lime‐juice (LJ), lime solution (LS), Calotropis procera stem extract (BSE) and calcium sulphate solution (CSS) fresh yields of tofu ranged from 318 to 380 per 200 g of bean, moisture content 60 to 72 per cent and protein 51 to 62 per cent. Yield of tofu coagulated with CSS was the highest (p < 0.05). Tofu coagulated with LS, AS, and FML gave similar yields which was significantly (p < 0.05) higher than LJ and BSE coagulated tofu. The moisture content ranged from 60 to 72 per cent.

LS coagulated tofu had highest moisture content (p < 0.001) while AS coagulated tofu gave the lowest moisture content (p < 0.001). Protein content was significantly highest in LS coagulated tofu and closely followed by the value for FML coagulated tofu (p < 0.001). Sensory scores for both fresh and fried tofu showed that FML coagulated tofu was the most preferred by tasters in all parameters tested.

Fermented maize liquor is recommended for use in tofu production where available, based on its comparative yield, protein content and the superior acceptability attributes of tofu produced from it. The production of tofu using FML as coagulant could be easily achieved from an enterprise that only involves low capital input, thus making tofu a cheap and affordable source of protein for combating protein malnutrition.

There is a huge gap between actual and achievable yields of maize which threatens household food security in Ghana. Low adoption of improved maize production technologies coupled with poor compliance with Council for Scientific and Industrial Research (CSIR) recommended maize production practices is identified as the cause of low yields. This study assessed farmers' compliance with CSIR recommended production practices and its effects on yield.

Using a structured questionnaire, a cross-sectional survey of 150 respondents were interviewed for the study. Descriptive statistics, awareness and compliance indices, probit model and Garret ranking technique were the methods of analysis employed in the study.

The results showed that farmers are highly aware, have adopted and hardly comply with standards of applications of CSIR recommended production practices. Farm size, age, educational level and female gender significantly influenced compliance with recommended production practices. Also, compliance with recommended production practices increase maize yield.

Policies aim at addressing yield gap in maize production should be targeted at improving farmers' level of compliance with production practices by addressing some constraints through farmer credit and subsidy programmes to help farmers increase their level of compliance. The fact that farmers have adopted recommended production practices does not necessarily mean they will have higher yields. The study generates important insights about how well farmers have been adhering to standards of adoption of recommended production practices.

This paper aims to provide empirical evidence on the El Nino and its effects on maize production in three municipalities: Ejura, Techiman and Wenchi in the transitional zone of Ghana. Using a mixed approach, the study details the effects of the El Nino on rainy season characteristics, particularly, rainfall amounts and distribution, onset and cessation of rains, duration of the rainy season and total seasonal rainfall and how it impacted smallholder maize production.

The study used a mixed method approach in collecting and analyzing data. For stronger evidence building, (Creswell, 2013) the authors combined interviews and focus group discussions (FGD) to collect the qualitative data. Semi-structured questionnaires were administered to extension officers, management information system officers and other relevant personnel of the Ministry of Agriculture in the three municipalities. Six FGD’s were held for maize farmers in six communities in all three municipalities.

The study shows that the 2015 El Nino had dire consequences on farm yields, subsequently affecting farmer’s incomes and livelihoods. The study further finds that complex socio-cultural factors, some unrelated to the El Nino, aggravated the effects on maize farmers. These include the lack of adequate climatic information, predominance of rain-fed farming, a lack of capacity to adapt and existing levels of poverty.

The study recommends inter alia, appropriate use of seasonal rainfall forecasting to enhance better farming decision-making and the development of elaborate climate variability interventions by national and local agencies.

This paper aims to investigate how climatic, market and policy factors interact to determine food production in Togo. Specifically, we estimate acreage and yield response to market prices, weather and policy changes for maize and rice.

We use panel data estimators in a Seemingly Unrelated Regressions Equation (SURE) model with region-level data from the Food and Agriculture Organization statistics department and the National Oceanic and Atmospheric Administration (NOAA) of the US Department of commerce.

We found lower fertilizer price and higher grain price effects on maize acreage and yield. In addition, we found a positive effect of expected rice price on both its acreage and yield. As expected, rainfall during planting months has a significant impact on both maize (April) and paddy (May) acreage allocations. Similarly, total rainfall during the growing season has a positive impact on both maize and paddy yields. Moreover, recent agricultural policy initiative designed to boost domestic food production has significantly increased acreage and yield for maize, and yield for paddy, especially the strategy for agricultural growth.

The dataset includes region-level observations from 1991 to 2012 which limits the observation span. However, we had enough variability in key variables to determine the estimated coefficients.

Although the dataset is limited in time (1991–2012) and uses national-level output prices, this investigation reveals that cropland allocation to maize and rice is sensitive to fertilizer and grain prices, weather expectations and policy interventions. These findings provide evidence for sustainable food production and productivity enhancement in Togo.

Understanding drivers of cropland allocation and cereal yield contribute to better food security and poverty reduction in developing countries, especially Togo.

Prior to this study, little was known on the effect of price, climate and policy on cropland allocation in Togo. This investigation contributes significantly to filling this knowledge gap and provides insights for effective interventions.

In connection with the suggestion recently made in the BRITISH FOOD JOURNAL to the effect that a National Pure Food Association should be established it is of importance to call attention to the fact that a society describing itself as the “League for the Defence of Human Life” has been recently formed in Paris with the object of preventing the frauds practised by dishonest traders upon their customers. One of the obligations entered into by the members of the League is to discover and prosecute persons engaged in the sale of adulterated or injurious articles of food and drink. Judging from the recent reports of the proceedings of certain Parisian tradesmen it would appear that a society of this description has much scope for its operations in the French Metropolis, and, as we have suggested, a society with similar objects might with advantage be formed in this country, with branches in all the principal cities and towns. With the legal machinery placed at the disposal of local authorities, cumbrous, inadequate and weak as it is, much more might be done in the way of repression if only the responsible authorities could be brought better to appreciate their duty.

Improving the adoption rates of proven innovative practices in bean farming and their impacts on livelihoods requires persistent promotion of practices, complemented by rigorous socioeconomic analysis that recognises the diversity of smallholder farmers. The purpose of this paper is to typify farm households in Angonia district of Mozambique, based on their socioeconomic characteristics prompting the adoption of proven innovative practices in bean production, management, and marketing.

The authors use a multivariate statistical analysis approach that combines principal component analysis, and cluster analysis to clearly identify five distinctive farm household types with respect to the adoption of proven innovative practices in smallholder bean farming using socio-economic factors.

The study findings show that various socioeconomic factors define clusters and can be associated with the adoption and use of innovative practices in smallholder bean farming. The five farm types identified are: female landowners with small farm sizes (29.52 per cent); educated farmers with access to credit (6.63 per cent); relatively rich male land owners with large farm sizes and low education (8.73 per cent); youthful, inexperienced and poor male farmers (6.33 per cent); and experienced female farmers with high labour endowments (8.43 per cent). The respective farm types seemed to have different patterns in the adoption of proven innovative practices in bean farming.

The authors recommend that policy makers promote strategies meant to raise adoption of innovative practices in bean production, management and marketing in Mozambique that takes into account household diversity. The farm types identified by this study can be a good starting point for guiding such future efforts.

Considering Brazil as a food producer with global prominence and the urgency for food security in some developing countries, the purpose of this paper is to investigate the exports of Brazilian dry-beans against food security of its buyers.

The investigation was conducted through analysis of data from official databases as FAO and WHO. This study elaborated dispersion maps crossing characteristics of the international buyers of Brazilian dry-beans considering their food security situations.

Brazil has a high domestic consumption of dry-beans, and exports are seen as a secondary activity. However, its production is superior to their domestic needs. Exports of Brazilian dry-beans are generally volatile and unstable. Evidence suggests that countries with serious problems of child and population’s malnutrition (e.g. India and Angola) buy more Brazilian dry-beans. However, their domestic consumptions are still low.

This research based only on exports of dry-bean is faced as a significant limitation. Future studies adding other staple foods commonly consumed by economically disadvantaged populations may contribute to the investigation of the role of Brazil against the need for food security in developing countries and emerging economies.

Social implications are focussed in the pursuit of malnutrition decrease in the populations of developing countries through the consumption of nutritionally rich and economically viable food, such as dry-beans.

The original value is based on the analysis of Brazilian dry-beans production and trades and its potential to contribute to nutritional safety and food security in developing countries.

This chapter examines how Maragoli women farmers’ plot-level crop control, individual, and household variables affect yields. This chapter contributes to a holistic understanding of the ramifications of quantitative and qualitative factors informing women farmers’ plot-level undertakings and yields as well as their innovative and creative strategies for optimizing output. It broadens the existing debate in the sub-Saharan African agricultural production literature by suggesting a composite measure of plot-level crop control as one factor influencing women farmers’ yields even in situations where land is owned by someone else. It also provides a rich discussion of the various and interlocking qualitative factors distorting women farmers’ incentive structures, efforts to increase plot-level yields and their strategies for minimizing the detrimental effects of the same.

A multimethod quantitative and qualitative ethnographic case study approach was used in this study.

This chapter demonstrates that women strategically bargained and invested more of their productive resources on the plots where they anticipated the greatest individual gains.

This chapter underscores women farmers’ ability to boost agricultural output when there are appropriate incentives for them to do so and suggests the theoretical and practical relevance of secure control and property rights over the products of the land not for the household (head), but for the cultivator. The chapter demonstrates and reaffirms that Africa women farmers respond appropriately to incentives and suggests that there is need for a customized, renewed, and sustained emphasis on women farmers’ empowerment and inclusion in all levels in the agricultural sector in order to actualize increased yields. Investing in women farmers and implementing policies that narrow existing gender disparities in African agricultural production systems is holistically beneficial.
