“…For life saving irrigations using surface water, an insitu micro pond (120 m 2 only with a depth of 1.5 m) has to be dug out in 1/3 rd of an acre (1333 m 2 ) sacrificing 9 percent of its area at the lowest corner of the field to harvest rain water. It can collect runoff water up to 1,80,000 litres of water or even more if the dugout soil is used for making embankment over it (Photo 4, [20,21]. At ICAR-CRIJAF, Kolkata, in last week of June (2010), it was observed that runoff collection from one 30 mm rain from 1/3 rd an acre was 60000 litres of water in such dug out insitu ponds.…”

Under changing climatic scenario, the rainfall amount and its distribution over space and time have become uncertain during the rice growing season which is also affecting rice production very often. Under deficit rainfall (50% & 19% in 2010 and 2012) from dry sowing or dry transplanting of rice to its harvest (48-52 cm rainfall from August to October), 42.8 q/ha coarse rice (cv, Annada) and 29-45 q/ha medium rice (cv. Satabdi and Himsagar) were harvested with one irrigation of 7.5 cm at panicle initiation stage. Water productivity ranged from 1250 to 1810 lit/kg of raw rice in different years. Dry seeded/dry transplanted rice was established receiving 55 to 74 mm rainfall within seven days. However, one supplemental irrigation following dry sowing/transplanting will ensure better seedlings establishment. Soil mulching by CRIJAF nail weeder at field capacity at 6-21 days after rice dry transplanting/dry sowing will maintain better hydro thermal regime and aeration of soil under deficit rainfall and ascertain composite weed control. Field capacity moisture during rice growth was enough to produce 45q/ha grain yield. This practice of rice production will mimimise methane gas emission over waterlogged rice paddies. In situ rain water harvesting in micro pond (12 m x 10 m x 1.5 m) sacrificing 9 per cent of total area (1333 m2) at lowest corner of the field provides life saving irrigation and produced 3-3.5 tonnes medium rice/ha. Through these micro ponds (7 in one hectare), in porous alluvial or sandy loam soils, annually around 3.58 to 7.47 crore litres of water can be recharged/ha to the unconfined aquifer in rainy season (July to September). Inter/relay cropping in rice field will produce 3.5 to 4.5 tonnes of rice along with 15- 200 q of different vegetables/ha, increase nutritional security of resource poor farmers, net return and make effective utilization of rainwater. Under deficit rainfall, as alternate crops of rice, yield of rain fed green gram (cv. Pant mung-5, RMG 62), arhar (UPAS -120) and sweet corn green cobs on ridges, were 21-23 q, 30 q/ha and 1,20,000 numbers/ha respectively. Adopting these rice production/intercrop/alternate crop/water harvesting technologies, sustainability can be ensured under a deficit rainfall, in current changing climatic scenario.

“…However, while flushing the body of water, sedimented pollutants are reintroduced into the body of water, causing two secondary pollutions, affecting the water bodies of the downstream basins and causing specific pollution in the downstream water bodies. On this basis, due to the introduction of a large amount of new water into the water body, the original river water level rise is very likely to cause the river to divert, and the project cost is huge, which further shows that this method cannot solve the fundamental problem [18,19].…”

With the rapid development of industrial and agricultural production, the rapid growth of population, and the acceleration of urbanization, the problem of water pollution is becoming more and more serious. Water shortages and pollution disrupt the balance of ecosystems and seriously limit people’s health and rapid economic development. Nowadays, the method of repairing sewage bodies using microbial landscape aquatic plants is attracting more and more attention, and it is a big challenge to maintain the sustainable development of human beings and nature. This paper uses floating rafts to combine microorganisms and landscape aquatic plants to conduct sewage treatment experiments. According to microorganisms, landscape aquatic plants absorb nutrients in the water body, examine the changes in water quality during the restoration of microorganisms’ landscape aquatic plants, and establish the growth of microorganisms’ landscape aquatic plants. The relationship with changes in water quality aims to provide a theoretical basis for the treatment of slow-flowing water bodies such as lakes, reservoirs, large artificial ponds, and rivers. In this paper, the experiments are divided into four groups (A (experimental sewage + microbial inoculant), B (experimental sewage + plant), C (experimental sewage + microbial inoculant + plant), and D (experimental sewage)). It can be divided into the total nitrogen content, total phosphorus content, and COD value data, and chromaticity detection of each group of the test is continuously monitored weekly to comprehensively detect and observe the repair effect on contaminated water bodies. The experiment proved that the water quality of the three treatment groups was significantly clearer than that of the blank control group, and its clarity: microorganism + plant > microorganism > plant > blank control group. This shows that the combination of microorganisms and landscape aquatic plants can effectively reduce the various pollutants contained in sewage and reduce the color of sewage. Treating sewage using plant technology that combines microorganisms is feasible and promising.

“…The decomposition of the parenchymatous tissues proceeds due to microbial enzyme secretion (Haque et al 2001). In recent years, microbial consortium approaches have been highly used to shorten the retting time and to upgrade the retting and fiber quality (Ghorai and Chakraborty 2020). Water absorption and liberation of soluble constituents like sugar, glucosides, and nitrogenous compounds from jute plants favor initial microbial growth.…”

The lignocellulolytic microbial systems from different parts of the world responsible for lignocellulosic biomass (LCB) like jute (Corchorus spp.) waste degradation, fiber modification, and bioenergy production are not limited to a specific prokaryotic or eukaryotic group. The industrial applications of these highly efficient bacterial, fungal and algal communities are related to the production of lignocellulolytic enzymes such as cellulase, hemicellulase, lignin-peroxidase, versatile peroxidase, laccase, thermostable oxidants, pectinase, etc. They are a blessing for the jute, dye, paper, pulp, and biofuel industries as they help to generate a sustainable ecosystem. The jute plant is lignocellulosic biomass so it can be utilized in various ways, from everyday goods to power generation. Jute industries generally use different physicochemical strategies to generate quality fiber and post-retting activities, but these approaches cannot produce desired products; hence microbial routes are best for quality fiber generation, waste remediation, and biofuel generation. To this end, this review summarizes the most important milestones of the development of the leading enzyme-producing cell factories and their engineering by genetic, metabolic, and synthetic biology approaches with the emergence of high throughput methods, such as site-directed mutagenesis and others that can analyze the relevant mutations to accelerate our understanding of lignocellulolytic enzymology.
