Nitrogen and phosphorus footprint analysis considering cultural and religious aspects of food diet: Case study of the Indian subcontinent
Nitrogen and phosphorus footprint analysis considering cultural and religious aspects of food diet: Case study of the Indian subcontinent
Thesis supervisor: Professor Kazuyo Matsubae
Thesis Keywords: culture and religion; food consumption; footprint analysis; nutrient management
Nitrogen (N) and phosphorus (P) are essential nutrients for all living organisms. Reactive N (N species apart from N gas) are essential for the growth of living beings. P is also a vital element that often limits the primary production of diverse ecosystems. Extreme N and P loss from food production and consumption result in both environmental and health problems. The footprint analysis explains both resource requirement and loss to the environment by human beings. The existing studies on N and P footprints are based on the average per capita food consumption. But food consumption diverges significantly among religions, depending on religious laws and rules. This study put the first step explaining the impact of the food consumption patterns of different religions on the N and P footprints using novel religion-sensitive calculation methods as a case study in the Indian subcontinent.

Enhancing farmers’ livelihood through adoption of conservation agriculture: A socioeconomic study
Enhancing farmers’ livelihood through adoption of conservation agriculture: A socioeconomic study
Thesis supervisor: Professor Md. Taj Uddin
Thesis Keywords: crop productivity and profitability; livelihood improvement; soil conservation
The research was conducted to evaluate the impact of practicing conservation agriculture on farmers’ livelihood enhancement in two districts of Bangladesh. A total of 120 farmers (20 from focal and 100 from control group) were surveyed from Jamalpur and Bogra districts for collecting necessary data and information. The benefit cost ratio of focal and control farmers in wheat and bean production were increased to 2.67 and 2.20, and 2.77 and 2.57 from 2.16 and 2.06, and 2.30 and 2.38, respectively after practicing conservation agriculture which indicated an increase in net return from crop farming. Crop productivity of focal farmers in response to the entire region was moderately lower compared to control farmers, but it was expected to increase in the next years of crop production if practicing conservation agriculture would be continued. From multidimensional poverty index (MPI), it was reflected that 24.6 and 45.8 percent focal and control farmers, respectively were deprived of all the index indicators of a single dimension or at a combination of the indicators across dimensions. On the contrary, 75.4 and 54.2 percent focal and control farmers, respectively were privileged of the indicators which implies a better livelihood condition of the focal farmers for practicing conservation agriculture. The major problems faced by the farmers included lack of good quality inputs, high price of inputs, lack of knowledge on conservation agriculture practice, less production due to minimum tillage, lack of extension service, etc. Considering the research findings, some crucial policy recommendations have been arisen which are: input support and extension services should be properly implemented, and initiative for scientific and technical training programmes should be arranged by different government and non-government organizations to enrich the knowledge of the farmers on conservation agriculture practice.
