On the other hand, there is an urgent need to introduce new environmentally friendly energy. New clean energy includes renewable energy such as solar power, wind power, geothermal power, ocean, hydropower, and hydrogen energy has been attracting significant attention in recent years. In this work hydrogen production by using different acid solutions and different co-catalysts were successfully achieved. Maximum production was 1767 μmol g-1 when Pd was used and 2229 μmol g-1 when oxalic acid was applied. The mechanism could be attributed to that promotion of hydrogen production on the surface of metal particles (Pd) can be considered. This is because the electrons that have moved to the conduction band move from the top of TiO2 onto the surface of the co-catalyst particles, as a result promotes the reduction reaction and improves the ability to generate hydrogen.","PeriodicalId":215601,"journal":{"name":"INWASCON Technology Magazine","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125621218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper reviews some relevant paperwork to explore the present situation of the food system and the probable solutions for sustainable food security. Today, 690 million people are hungry and overall food demand is estimated to rise by 50% with the increase in population reaching about 10 billion by 2050. Meanwhile, the supply system loses 1.3 billion tons of food produced every year. Also, the world is facing the problem of hunger and obesity simultaneously. By 2050, adequate feeding of the growing population will necessitate an extra 593 million ha generating 7.4 quadrillion calories, which is more than 1.5 times as produced in 2010. Furthermore, 1/4th of total greenhouse gas (GHG) emissions are attributed to the agriculture sector alone so, we have the dare to meet the increasing global food demand while minimizing adverse environmental impact. The paper’s main contribution lies in the analytical study of different food security approaches. The paper shall help the policymakers to focus on the best measures while formulating a strategy to combat hunger and climate change at the same time. It suggests giving major attention to the breeding programs, increasing cropping intensity, intercropping, rediscovering NUS, more plant-based diet, reduction of food loss and reforestation, peatland restoration, and efficient water utilization for sustainable food security.","PeriodicalId":215601,"journal":{"name":"INWASCON Technology Magazine","volume":"97 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133455228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Without seed the existence of living being in earth is not possible. These seed if viable, under favourable condition grown into green plants. These green plants are the only producer of the planet on which all creatures depend upon. So, seeds are the major element for production, from which other consumers can survive. So, for the human survival we need high yield from optimum input. Seeds are major factor in which yield mostly depend upon. Hence selection of seed must be done with proper study. A viable, pure seed free from disease and pest, having high genetic potential must be selected and sown in its suitable agro climatic condition at its seasonal time for the expected yield. Quality seeds have different parameters like good germination, enough moisture, high physical and physiological purity, disease and pest free. So that quality seed has higher capacity of greater crop stand and production. In context of Nepal, many people are affected from food insecurity. Production of agricultural product has comparatively lowered. Nepal is insufficient in production. So the present production is not able to meet the food demand of existing population. Hence, to increase the fulfilment of food demand of existing population, production and distribution of quality seed is* required. Many agricultural operations are done to help the plant for its better performance such that the risk in yield loss is minimized. Seed with high yield, disease resistance and moisture/drought tolerating capacity must be preserved. These characters are needed for other future research works so, whether its wild or domesticated species, these character bearing seed must be conserved in seed banks. A country can become self-sufficient, and food secured with the application of quality seed on production technology, building of cold store in different regions for storage and prevention of post harvest loss and finally making food accessible to everyone.","PeriodicalId":215601,"journal":{"name":"INWASCON Technology Magazine","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131704214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Global warming became a serious threat to crop productivity as heat stress sig nificantly reduced grain yield. Although the different traits related to high grain yield have beenidentified, the combination of traits that optimize high grain yield has not been established. The later sown experiments were exposed to higher temperatures at the critical reproductive and grain-filling stages of development. The influence of high temperatures was highest during anthesis, and with every 1% increase in average maximum temperature over the optimum of 25 degrees Celsius, grain yield was lowered by 4% to 7%. High temperature reduced yield, plant height, grain weight and days to anthesis and maturity, and increased the percentage of screenings and grain protein content. Genotypes that produced higher yield under heat stress had shorter days to flowering and maturity, higher NDVI during grain filling, greater chlorophyll content at the milk stage of grain fill, taller plants, greater grain weight and number, and lower screenings compared with the benchmark cultivar Sun top (main factors contributing to yield increase/parameters).","PeriodicalId":215601,"journal":{"name":"INWASCON Technology Magazine","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125093047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
