RESUMEN
Substantial loss of nitrogen (N) in reactive forms (nitrogen species except for N2) induced by agro-food system is a cause of the environmental degradation and harms human health. The main factors influencing the food N footprint of the Indian Subcontinent (ISC) are the nitrogen use efficiency (NUE) of crop cultivation and religious dietary cultures. In this study, we assess the food N footprint of the ISC and establish reduction scenarios toward 2050. We used a religion-sensitive N-Calculator method and food consumption data from the Food and Agriculture Organization of the United Nations to estimate the food N footprint of the ISC of different religious communities. We developed four reduction scenarios as follows: The business-as-usual scenario; a 30% increase in the crop cultivation NUE; altered protein supplies to the healthy EAT-Lancet reference diet considering religious food taboos; and an integrated approach with a 30% increase in the NUE increase and the altered diet. We used the long short-term memory recurrent neural network approach to predict the future. The study revealed that the average food N footprint per-capita per-year increased from 7.94 kg-N in the 1960s to 8.43 kg-N in the early 2010s, and the crop cultivation NUE was reduced to less than 40%. Buddhists had the lowest footprint over the period. An increase in the NUE of the crop cultivation and an altered diet results in a 13% reduction in the N footprint compared to the business-as-usual scenario. We conclude that improved crop cultivation NUEs and an altered religion-specific healthy diet would reduce the N footprint.
RESUMEN
The excessive consumption of nitrogen (N) and phosphorus (P), two vital nutrients for living organisms, is associated with negative environmental and health impacts. While food production contributes to a large amount of N and P loss to the environment, very little N and P is consumed as food. Food habits are affected by multiple regulations, including the dietary restrictions and dictates of various religions. In this study, religion-sensitive N-Calculator and P-Calculator approaches were used to determine the impact of religious dietary culture on the food N and P footprints of India in the major religious communities. Using 2013 data, the food N footprint of Hindus, Muslims, Christians, and Buddhists was 10.70, 11.45, 11.47, and 7.39 kg-N capita-1 year-1 (10.82 kg-N capita-1 year-1 was the national average), and the food P footprint was 1.46, 1.58, 1.04. and 1.58 kg-P capita-1 year-1 (1.48 kg-P capita-1 year-1 was the national average). The findings highlight the impact of individual choice on the N and P food footprints, and the importance of encouraging the followers of religion to follow a diet consistent with the food culture of that religion. The results of this study are a clear indication of the requirement for religion-sensitive analyses in the collecting of data pertinent to a particular country for use in making government policies designed to improve the recycling of food waste and the treatment of wastewater.

The study assessed the economic, environmental and sustainability issues of organic shrimp farming in Bangladesh. Following stratified random sampling technique, 60 farmers were interviewed from several villages of Assasuni upazila under Satkhira district. The study revealed that productivity of organic shrimp per hectare was 383 pound and benefit cost ratio was 1.91 which meant that organic shrimp farming was highly profitable. Educational level of household head, gher size and knowledge on organic shrimp production had positive and significant influence in adopting organic shrimp production by the farmers. Cause-effect-mitigation analysis pointed out that organic shrimp farming could mitigate the adverse effects on environment caused by traditional shrimp farming. Appropriate climate and environment for organic shrimp culture was found as major strength and comparative profitability than traditional shrimp production was found as major opportunity of organic shrimp production. The study confirmed sustainability of organic shrimp production from the standpoint of consuming energy, protecting environment, economic feasibility and social/political equity. The study recommends that farmers should be trained to follow the work instructions and principles of organic shrimp production and the application of good management practices (GMPs) should be ensured for reducing the disease outbreak risk.

The data used in this article elucidated crop intensification and farmers' food security status through GO-NGO support in Bangladesh. A total of 200 farmers (100 from non-supported and 100 from GO-NGO supported) were selected for data collection using purposive sampling technique. The collected data showed that GO-NGO support has a significant impact on changes in agricultural enterprises. Majority (63.3%) of the households belong to the low intensity category for non-supported farmers. In case of GO-NGO supported farmers, majority (73.3%) of the households belong to the high intensity category. The food security indices values showed that the food security index for non-supported farm households was 0.97 and for GO-NGO supported farm households, it was 1.07.
RESUMEN
The study was conducted to document farmers' livelihood aspects and agribusiness potentials in wetland areas of Bangladesh. A total of 120 farmers and 24 service providers were interviewed for data collection. Most of the farmers were small farmers having less than 1.0 ha of cultivable land. The differences in productivity of crop farming and poultry rearing between wetland area and main land were statistically significant. Favorable farm environment and proper utilization of agricultural resources were major strength and opportunity. The data may be helpful for formation of agribusiness clusters involving input suppliers, credit/financial organizations and different support service providers for more income, better nutrition and improved livelihood of the wetland people.
