Impact of Crop Diversification on Household Food and Nutrition Security in Southern and Central Mali

Many African countries, including Mali, depend on the production of a single or a limited range of crops for national food security. In Mali, this heavy reliance on a range of basic commodities or staple crops, or even just one, exacerbates multiple risks to agricultural production, rural livelihoods, and nutrition. With this in mind, the smart food campaign was initiated to strengthen the resilience and nutritional situation of households and peasant communities where the diet is mainly cereal-based and remains very undiversified and poor in essential micronutrients. As part of the campaign, our study aims to analyze the impact of agricultural diversification on food consumption and household nutritional security. The analysis uses survey data from 332 individuals randomly selected. Multinomial logistic regression and the Simpson diversity index were used to determine the index and estimate the determinants of crop diversification. The consumption score index weighted by consumption frequency and anthropometric indices (for children) were used to assess the nutritional status of households. The results show four types of strategies of diversification: 7.55% are cereals only, 5.66% combine millet–sorghum–groundnut, 41.51% combine millet–sorghum–groundnut–cowpea, and 45.28% combine millet–sorghum–groundnut–cowpea–maize. The estimation of the regression model shows that socioeconomic factors have a positive influence. With a consumption score index of 34 in the villages and 40.5 in Bamako, based on eight food groups, we find that the quality of food is insufficient in rural areas, but it is acceptable in the urban center of Bamako. Analysis of the nutritional status of children aged 6–48 months reveals that 30% of the surveyed population is in a situation of nutritional insecurity (all forms combined). To help improve crop diversification and the nutritional quality of foods, we suggest, among other things, subsidies and public spending to facilitate access to inputs that allow the acquisition of a wider range of inputs and services, intensification of nutrition awareness, and education programs to maximize the incentive to consume nutritious foods from self-production and market purchases. Finally, we propose to facilitate access to technologies promoting food diversification and improving food and nutritional security, particularly in rural areas.

Determinants of Crop Diversification in Bangladesh: An Econometric Analysis

This study aims to investigate the factors that influence household behaviour in cultivating the diversified crops on their cultivable land in Bangladesh. Cragg’s alternative tobit model has been applied to a unique rural household level dataset to find the catalysts of crop diversification. The results obtained portrayed a mixed impression of crop diversification in the country. The estimated results have revealed that the male head of household, the accessibility of information, a greater number of farming parcels and the availability of hired labour seem to govern the decision of a farming household to participate in non-rice crop production, while factors such as the total amount of land, agricultural extension service and irrigation facilities influence rice cultivation. Moreover, the findings obtained from the same Cragg’s alternative tobit model estimation for the Aman, Boro and Aus seasons have also revealed a similar depiction of crop diversification in Bangladesh.

Optimizing Plant Disease Management in Agricultural Ecosystems Through Rational In-Crop Diversification

Biodiversity plays multifaceted roles in societal development and ecological sustainability. In agricultural ecosystems, using biodiversity to mitigate plant diseases has received renewed attention in recent years but our knowledge of the best ways of using biodiversity to control plant diseases is still incomplete. In term of in-crop diversification, it is not clear how genetic diversity per se in host populations interacts with identifiable resistance and other functional traits of component genotypes to mitigate disease epidemics and what is the best way of structuring mixture populations. In this study, we created a series of host populations by mixing different numbers of potato varieties showing different late blight resistance levels in different proportions. The amount of naturally occurring late blight disease in the mixture populations was recorded weekly during the potato growing seasons. The percentage of disease reduction (PDR) in the mixture populations was calculated by comparing their observed late blight levels relative to that expected when they were planted in pure stands. We found that PDR in the mixtures increased as the number of varieties and the difference in host resistance (DHR) between the component varieties increased. However, the level of host resistance in the potato varieties had little impact on PDR. In mixtures involving two varieties, the optimum proportion of component varieties for the best PDR depended on their DHR, with an increasing skewness to one of the component varieties as the DHR between the component varieties increased. These results indicate that mixing crop varieties can significantly reduce disease epidemics in the field. To achieve the best disease mitigation, growers should include as many varieties as possible in mixtures or, if only two component mixtures are possible, increase DHR among the component varieties.

Minor Crops: A Path towards Crop Diversification

With passage of time, there has been paradigm shift observed in dietary intake of people henceforth disturb­ing the balance of nutrients required by the body. Due to the leap towards major cereal crops to feed the growing population, impetus towards minor crops have observed a continuous decline. This ap­proach have also led to emergence of various nutritional deficiencies. Though these crops are neglected but are treasure house of various nutrients needed for all-round development of an individual. This re­view examines and compares the nutritional aspects of major cereal crops to minor crops and also dis­cusses the abundant health benefits provided by few minor crops, as well their prevalence in context to Indian subcontinent.

Agricultural Growth Diagnostics: Identifying the Binding Constraints and Policy Remedies for Bihar, India

Agriculture plays a significant role in economic development of underdeveloped regions. Multiple factors influence the performance of agricultural sector but a few of these have a strong bearing on its growth. This study develops a growth diagnostics framework for agricultural sector in Bihar, located in eastern India, to identify the most binding constraints. The study results show that poor functioning of agricultural markets and low-level of crop diversification are the important reasons for low agricultural growth in Bihar. Rise in price instability of agricultural produces indicates a weak price transmission across the markets even after repealing the Agricultural Produce Market Committee Act. Poor market linkages and non-functioning producer collectives at village-level affect the farmers’ motivation for undertaking crop diversification. Hence, policy suggestions to overcome these binding constraints include the state provisioning of basic market infrastructure to attract private investment in agricultural marketing, strengthening the Farmer Producer Organisations, and framing a comprehensive policy on crop diversification.

Assessment of Yield Gaps and Economics through Frontline Demonstration in Participatory Mode on Chickpea (Cicer arietinum L.) under Eastern Zone of Haryana

Background: Cluster frontline demonstration (CFLD) with improved technology plays a vital role in enhancing the production potential of pulses as well as socio-economic level of farmers and it also proved that it improves soil heath through crop diversification by optimizing diversified microhabitats that benefit soil microbial community. Methods: KVK, ICAR-NDRI, Karnal (Haryana) conducted 220 demonstrations on chickpea variety HC-1 and HC-5 over an area of 80 ha during Rabi season 2017-18 to 2020-21. The demonstrated technology was improved variety HC-1 and HC-5, optimum seed rate and spacing, seed and soil treatment with bio-fungicide and application of Integrated Pest Management (IPM) module for the management of diseases and insects. Result: The result of the CFLDs showed that on an average yield of chickpea seed under improved technology, ranged from 11.41 q/ha to 20 q/ha which was 25.06 per cent more as compared to farmer practices. The study depicted, the mean technology gap of 9.01 q/ha, the mean extension gap of 3.70 q/ha and the mean technology index of 36.7 per cent. The study concluded that from one hectare a net income of Rs. 47565/- can be obtained, additional return of Rs. 10404/, effective gain of Rs. 8289 and B:C ratio obtained were 2.63 under incorporation of improved technology as compared to local check. By conducting CFLD of proven technologies, yield of crop could be enhanced to a great extent with ultimately increment in the income level of small and marginal farmers.

Big Boro rice harvest during COVID-19 pandemic: an optimism for resilient rice system in Bangladesh

The ‘big Boro rice harvest’ in 2021 amidst the COVID-19 pandemic has created new optimism for a resilient rice system in Bangladesh. Boro rice (dry season rice) has appeared as the strategic crop in sustaining resilience in the national rice system and food security with a steady rise in production trend. However, the prospect of Boro rice has been challenged by a myriad of factors such as changing climate, hydrological regimes, value-chain and crop diversification. Any unexpected production loss of Boro rice might bring about a big setback in total food security. Therefore, holistic policy planning and research supports, strong value-chain, efficient procurement system and, farmer’s capacity development have been suggested to sustain the production trend of Boro rice in the year to come.
