“…This finding is in line with a study conducted in districts of Tanzania Morogoro with 20% low dietary diversity, 24 South Gonder Ethiopia with 21.1%, 11 Yayu Southwest Ethiopia with 17.5% 22 and Yayu Ilu Abbabora Zone with 19% low dietary diversity. 23 In contrast, the findings of the current study are lower than those of a study conducted in Bangladesh (42%), low dietary diversity, 25 Ghana (36.4%),, 26 and Tanzania Dodoma district (35%). 24 The possible explanation could be due to geographical variation and lack of enough production since the study was conducted in the winter season.…”

Background Low dietary diversity is the main public health issue in developing countries. Despite its burden, there is a paucity of information on the dietary diversity of households and related factors in rural residents of southern Ethiopia. Therefore, this study assessed household dietary diversity and associated factors among rural residents of Gomole district. Methods A community-based cross-sectional study design was conducted from November 1 to December 30, 2020, among 554 randomly selected rural households. Data were collected by using pretested structured face-to-face interviews about dietary intake by any household members within the past 24 h. The data were coded and entered into Epi data 3.1 and analyzed using Statistical Package for Social Sciences version 23. Both descriptive and analytic statistics were employed. Adjusted odds ratios (AORs) together with 95% confidence intervals and p values of less than 0.05 were used to declare statistical significance. Results Out of the total, 19% (95%; CI = 15.7–22.2) of households had adequate dietary diversity scores. The mean (±SD) dietary diversity score was 5.12 (±1.6). The most consumed food groups in the study area were cereals/grains (96.4%), condiments (salt and beverages (tea)) (84.3%) and milk and milk products (80%). The sex of the household head (AOR = 2.31, 95% CI: 1.04–5.13), bank account ownership (AOR = 2.18, 95% CI: 1.04–4.59), and livestock ownership (AOR = 4.75, 95% CI: 1.35–16.73) were positively associated with dietary diversity. However, distance to the marketplace (AOR = 0.11, 95% CI: 0.02–0.56) was negatively associated with adequate dietary diversity. Conclusion There is low dietary diversity among households of study area. Improving livestock rearing and bank accounts should be strengthened through strong intersectional collaboration to alleviate the problem.

“…However, some areas are still prone to drought [ 40 ]. The strong decreases in yield for extreme wet conditions found in this study may be due to extreme events, such as cyclones, that are more frequent in these regions of the world [ 41 , 42 ].…”

Interactions between temperature and drought in global and regional crop yield variability during 1961-2014

Inter-annual crop yield variation is driven in large parts by climate variability, wherein the climate components of temperature and precipitation often play the biggest role. Nonlinear effects of temperature on yield as well as interactions among the climate variables have to be considered. Links between climate and crop yield variability have been previously studied, both globally and at regional scales, but typically with additive models with no interactions, or when interactions were included, with implications not fully explained. In this study yearly country level yields of maize, rice, soybeans, and wheat of the top producing countries were combined with growing season temperature and SPEI (standardized precipitation evapotranspiration index) to determine interaction and intensification effects of climate variability on crop yield variability during 1961–2014. For maize, soybeans, and wheat, heat and dryness significantly reduced yields globally, while global effects for rice were not significant. But because of interactions, heat was more damaging in dry than in normal conditions for maize and wheat, and temperature effects were not significant in wet conditions for maize, soybeans, and wheat. Country yield responses to climate variability naturally differed between the top producing countries, but an accurate description of interaction effects at the country scale required sub-national data (shown only for the USA). Climate intensification, that is consecutive dry or warm years, reduced yields additionally in some cases, however, this might be linked to spillover effects of multiple growing seasons. Consequently, the effect of temperature on yields might be underestimated in dry conditions: While there were no significant global effects of temperature for maize and soybeans yields for average SPEI, the combined effects of high temperatures and drought significantly decreased yields of maize, soybeans, and wheat by 11.6, 12.4, and 9.2%, respectively.

“…The coastline is 710 km long which is composed of the interface of various ecological and economic systems, including mangroves (the world's largest mangrove forest covers 6017 km 2 ), tidal flat, estuaries, seagrass, about 70 islands, accreted lands, beaches, a peninsula, rural settlements, urban and industrial areas, and ports (Hossain, 2001). The majority of the coastal inhabitants are poor, and exposed to both natural disasters and man‐made hazards (Rabbani et al, 2015; Shams & Shohel, 2016). Climate change‐driven events, such as sea‐level rise, cyclones, storm surges, coastal inundation, salinity intrusion, and land erosion are among the most common natural disasters.…”

The coastal zone of Bangladesh is suffering from a wide range of climate change‐driven hazards. Limited attention has been given to these zones' food security assessment. Therefore, this study aims to assess the status of food security and its determinants among different groups of Bangladeshi coastal households. It also identifies their livelihood risks and coping strategies during stressed situations. Data were collected from 1350 households from coastal districts through a questionnaire survey. Food security was calculated and compared with the recommended average (2400 kcal/capita/day). A binary logit model was used to identify the determinants of food security among rural coastal households. Livelihood risks and coping mechanisms were recorded through open‐ended questions. The findings of this study revealed that although on average, sampled households were food secure (2753 kcal/capita/day), 81% of landless households and 72% of marginal landholders within the sample appeared food insecure. Among various food items, rice supplied the greatest total daily calorie intake (1841.47 kcal), second was the edible oil (172.27 kcal). The regression model revealed that farm size, farm income, off‐farm income, and crop production had positive impacts on households' food security. Floods, salinity, heavy rainfall, and reduction of land productivity were high risks to the large farm households, while heavy rainfall, floods, and salinity were high risks to the landless farm households. To cope with these risks, the majority of large farm households used their savings and sold livestock and poultry as coping strategies. The landless and marginal farmers were mostly helped by nongovernmental and government‐run organizations, moved elsewhere to find work, sold their labor, and were involved in fishing. It was concluded that different groups of farmers face different challenges. Our findings indicate that in order to protect landless and marginal farmers, government should implement policies aimed at increasing crop production by means of prioritizing saline‐tolerant crop varieties and the creation of more job opportunities.
