“…In the literature, crop diversification is measured through a variety of indices indicating the extent of dispersion and concentration of activities in a given time and space. Among these indices, the Herfindahl index, Simpson index and entropy indices are widely used in the agricultural literature for diversification (Maji et al 2015). In the case of this study, the composite entropy index (CEI) is used.…”

This paper analyses the impact of climate variability on cereal, root and tuber crop diversification for selected West African countries during the period 1965-2014. The crop diversification index, combining cereal, root and tuber crops, was calculated through the composite entropy index. Climate variability is measured by the coefficient of variation of temperature and precipitation. A seemingly unrelated regression was used to estimate the relationship between climate variability and crop diversification by controlling for supply- and demand-side factors of crop diversification. Overall, the results reveal that variability in temperature and precipitation over decades did not have an adverse effect on cereal root and tuber crop diversification. A detailed analysis showed that Niger and Togo have been the most adapted to climate variability, while Ghana was the most affected, mainly by precipitation variability. The results also indicated that, on the supply side, the availability of agricultural land contributed to crop diversification. Productivity, which is expected to increase crop diversification, was positive and significant in very few countries. In the others, it was not enough to improve crop diversification. On the demand side, population growth and consumption led to crop diversification, particularly in the consumption of roots and tuber crops. This study suggests that greater diversification would mitigate the negative impact of climate variability. Therefore, regional and national agricultural policies aimed at increasing productivity are necessary to encourage farmers to diversify food crops under climate variability.

“…The functional fragmentation is STRUCTURE, FRAGMENTATION OF AGRICULTURAL LAND HOLDINGS mainly meant for crop diversification. Crop diversification is an important risk management tool for augmentation of farm income stabilization, employment generation, conservation of natural resources, poverty alleviation and export promotion (Maji et al 2015). Additionally, it fulfills household nutritional and fuel requirements, and organic supplements for farms.…”

Land structure and level of fragmentation in typical small-marginal agricultural holdings in India

et al. 2020

Farming in the Indian subcontinent is essentially small and marginal. With time, land size is fast declining and farmers are under pressure of generating more and more surplus under extreme resource competition. Land fragmentation has also increased severely in recent times, which might pose a threat to sustainability and food security soon by making agriculture unprofitable. The present study aims to portray the dismal condition of the land structure and level of land fragmentation of 141 small-marginal farming households in one of the most fertile agro-ecological villages of West Bengal in India, Rautari village in Chakdah block situated in Nadia district. Present investigation was conducted through well-structured field studies during 2016–17. The study reveals the existence of very traditional patriarchal land ownership patterns, and lack of women’s inclusion from property ownership rights. Farmlands are extremely fragmented with a high value of Simpson Index. Moreover, farmers with high technical efficiency fragment it even more to accommodate a greater number of crops in one growing season. A positive relation between farm area and production is derived from field data. Based on the prevailing situation, indicated by results, the study designed a comprehensive community and land resources utilization plan for the development of the community in the study area. The proposed comprehensive community and land resources utilization plan is a structured tool for extension services which will strengthen the capacity building programs for small-marginal farmers.

This paper analyses the impact of climate variability on cereal, root and tuber crops diversification for selected West Africa countries during the period 1965–2014. Crop diversification index, lumping together cereal, root and tuber crops, was calculated through the Composite Entropy Index. Climate variability is measured by the coefficient of variation of temperature and precipitation. A Seemingly Unrelated Regression was used to estimate the relationship between climate variability and crop diversification by controlling for supply and demand side factors of crop diversification.
