Abstract

The state of food and nutrition security in the world marks the foundation of a regular monitoring of advancement towards achieving food and nutritional security through household. India is facing complex nutrition problems and malnutrition remains an important public health issue. India itself is a home for the largest under-nourished and hungry population. Healthy and high-quality diets require consumption of a wide range of food categories in the right quantities. India achieved food security; however, achieving nutrition security requires an adequately diversified diet in terms of macronutrients and micronutrients. Fruits and vegetables are the good sources of micronutrients which are needed for healthier diets. India is a second largest producer of fruits and Vegetable in the world. During the year 2014-15 India produced 169.478 million metric tons of vegetables and 86.602 million metric tons of fruits. Majority of Indian population resides in rural areas and practicing agriculture and allied activities. To address such nutrition issues there is need for promoting nutrition sensitive production and advisory system in rural area. In recent years, the interest in leveraging agriculture to improve nutritional outcomes has been increased, especially at institutional level. Hence, to emphasis on nutritional aspects of rural people is possible through Agricultural Extension workers. There is global interest of leveraging better Agriculture Extension and advisory services as a basis of food and nutritional security. Connecting extension and rural advisory services with health has the potential to improve sustainability through fruits and vegetables as a source of nutrition. Agricultural extension and advisory workers are probably the best source to help to achieve nutritional education to farmers, through bio fortification, farm school, convergence of actors, participatory methodologies and Information Communication Technologies (ICT’s). The review paper aims at explaining the possibility of how nutrition can be integrated into extension and advisory services to reach rural people through Agricultural extension and rural advisory services (RAS) to address malnutrition in rural area.

Abstract

Estimation of Runoff is essential for planning and designing of soil and water conservation structures and computing the same practically from the field is tedious and time consuming process. Application of Environmental Protection Agency’s (EPA) Storm Water Management Model (SWMM) eradicates the complexities of estimating the Runoff which projects out hydrologic responses of rainfall-runoff processes. The present work deals with application of SWMM in a catchment area of farm tank located at AEC&RI Kumulur, Tamil Nadu, India where physical characteristics of the catchment area derived readily by using Arc GIS 10.1 which processes the elevation data collected from total station, generates Digital Elevation Model and delineates the catchment area. Land Use Map generated in Geographic information system (Arc GIS 10.1) is used as a backdrop image for compartmentalizing sub-catchments. The whole area is divided into six sub-catchments. The 20 year Precipitation data is collected from meteorological laboratory is segregated to hourly events using Indian Meteorological Department (IMD) reduction formulae and hydrographs are generated for the whole system. Runoff harvesting potential for 20 year over the catchment area is found out and statistical analysis had been done. Identification of years with abundant, average and arid rainfall and analysis of hydrologic processes such as precipitation, runoff, evaporation and infiltration depth during this years has been done. Calibration of runoff from a sub-catchment has also been done by installing stage level recorder in front of a weir and a runoff coefficient of 0.58 is obtained. SWMM is found to be a reliable methodology for estimating runoff from a semi urbanized catchment area.

Abstract

Farmers perception towards economic, environmental and social aspects in the adoption of Bt cotton and constraints towards the adoption of Bt cotton study was taken in Dharmaputi district of Tamil Nadu by surveying 120 farmers. The results showed that the perception of farmers towards economic, environmental and social aspects favoured Bt cotton. The major production constraint was lack of availability of pure and quality seeds, high incidence of sucking pests other than bollworm and the major marketing constraint were low price for the produce which should be taken care of by the State Government by implementing suitable price and distribution policy advocacy.

Abstract

Sunflower is affected by many diseases, of which Macrophomina phaseolina cause huge economical loss to the farmers. In this study, six isolates of Macrophomina phaseolina was isolated from infected root and maintained in pure culture. The isolates produced two types of mycelium viz. fluffy and oppressed with varied colony colour viz. deep black and blackish grey. The size of the sclerotia also varied among the isolates (Length 96.98 - 32.95µm: Breadth 55.71 - 28.35 µm). Pathogenicity test conducted using sand maize medium indicated that among the six isolates, the isolate OCM3 produced maximum disease incidence (72.37%). The virulent isolate OCM3 recorded maximum mycelial growth in potato dextrose agar medium (9.00 cm). The isolate was able to produce more mycelial growth in dextrose (8.94 cm) and maltose (8.83 cm) amended medium when compared to control. Similarly, the isolate produced maximum mycelial growth in urea (8.78 cm) and ammonium sulphate (7.12 cm) amended medium. This paper outlines the pathogenicity, morphological and cultural characters of Macrophomina phaseolina infecting sunflower.

Abstract

Mango powdery mildew incited by Oidium mangiferae Berthet is the most destructive disease attacking leaves, flowers and young fruits resulting in heavy yield loss upto 70%. Powdery mildew fungus is a biotrophic and high sugar demanding pathogen which grows only in the living tissues. Hence, it is difficult to grow and maintain the culture under laboratory condition. The present attempt has been carried out for evaluating the effective method of culturing the pathogen under in vitro condition. Four different isolation and inoculation techniques were evaluated using the susceptible mango cultivar Alphonso. The results showed that leaf twig bioassay method was found to be an effective isolation method under laboratory condition compared to spore suspension method using modified Potato Dextrose Agar (PDA) medium. Under greenhouse condition, spraying of conidial suspension was found to be the best method which recorded highest Percent Disease Index (PDI) of 52.22 during fourth week of pathogen inoculation, whereas leaf stapling method showed least PDI. Higher conidial germination is always favored by the presence of thin film of water on the leaf surface. Spraying of conidial suspension method provided the uniform spread of conidia along with water which resulted in the maximum PDI.

Abstract

An automatic irrigation control system has been designed to facilitate the automatic supply of adequate of water from a reservoir to field or domestic crops in all agricultural seasons. The objective is to remove human intervention for automatically maintaining the requisite moisture content of to optimize use of water in the process. The method employed is to continuously monitor the soil moisture level and to decide whether irrigation is needed or not. The adequate amount of moisture content can not only increase the yield but can result in water saving also. So the implementation of automation in irrigation is need of the hour but the technology should be affordable by common masses.

Abstract

Sesame is one of the ancient and most important oil seed crop and it has been called “Queen of Oilseed crops” by virtue of the excellent quality of its oil. Sesame crop is vulnerable to a number of diseases caused by a number of pathogens. Leaf blight caused by Alternaria sesami (Kawamura) Mohanty and Behera has become a serious problem. The causal organism of leaf blight of sesamum was identified as Alternaria sesami based on the colony morphology and spore characters. Bio efficacy of twenty antagonists, fifteen plant extracts (10%) and six different botanical oils (3%) were evaluated on the growth of Alternaria sesami causing leaf blight disease of sesamum under in vitro. Among the twenty antagonists, Pseudomonas spp. (PSA5) and Bacillus spp. (BNE4) were highly effective against A. sesami by 60.00 and 61.11 per cent respectively. Neem (Azadirachta indica) extract and eucalyptus (Eucalyptus globulus) oil showed the maximum of 80.00 and 64.44 per cent inhibition of mycelial growth of A. sesami at 10 and 3 per cent concentration respectively.

Abstract

The study has examined the opportunities for the new marketing tie up model for stabilizing prices of vegetables in Thanjavur District. The sample respondents include vegetable producing farmers, retailers and wholesalers. The study reveals that the cost of cultivation of brinjal was ₹ 50,038 per ha and bhendi was ₹ 43,913 per ha in Thanjavur district during 2018. With respect to the price prevailing among three identified channels for brinjal and bhendi, farmers received highest price in channel II. Retailers procured vegetables from wholesalers and farmers but relied more on wholesalers in the vegetable markets and procure less quantity from the farmers. For stabilizing vegetable prices, fixing fair price for the whole year and establishment of procurement centers at common places was the idea perceived by the farmers about initiating a tie up marketing. Regular supply of graded vegetables and in required quantity were the most perceived factors by the retailers about tie-up marketing. Consistent supply and acceptance of produce as per the agreement was the expectations of the both farmers and retailers in the new marketing tie up arrangement. Lack of co-ordination among producers to increase their bargaining power was the most important problem faced by farmers. To promote tie-up marketing the awareness level among the farmers need to be enhanced, creating collection points at feasible places and fixing fair price consent to both are the major suggestions for tie-up marketing of brinjal and bhendi.

Abstract

In this study thirty isolates of Trichoderma spp. were isolated from the rhizosphere soil of onion cultivated in southern districts of Tamil Nadu, India. The antagonistic potential of thirty isolates of Trichoderma spp. was tested against Fusarium oxysporum f.sp. cepae. Trichoderma sp. (T M2) recorded the maximum (85.66%) inhibition on the mycelial growth (1.29 cm) followed by T M4 with 80.88 per cent inhibition respectively. The Competitive Saprophytic ability (CSA) and colonization of Trichoderma sp. isolates were assessed with the effective twenty isolates, screened for antifungal activity. Among the twenty isolates tested, T M2 registered 88.09 per cent colonization followed by T M4 with 85.62 per cent colonization. All the other isolates were inferior to T M2 in its saprophytic ability. The antagonistic isolates of Trichoderma sp. were also tested for production of antifungal volatiles and their effect on the growth of F.o f.sp. cepae. All the isolates were found to produce volatile compounds, which inhibited the mycelial growth of test pathogen at varying levels from 19.11 to 70.33 per cent.

Abstract

Finger millet is one of the important millet crops widely cultivated across India. Although, it is known to be one of the hardiest crops, is affected by many diseases, of which foot rot caused by Sclerotium rolfsii has been on the rise especially under irrigated and high rainfall situations. Nine Trichoderma spp. and 10 Pseudomonas spp. isolated from cultivated soils of Mandya, Karnataka, India were screened in in-vitro against S. rolfsii. Among the bio-agents Chandagalu isolate (CT) of Trichoderma and Kannahatty isolate (KP) of Pseudomonas were found to be very effective in suppressing the foot rot of finger millet in susceptible variety Indaf-5. These two potential bio-agents when tested in different delivery methods under greenhouse conditions, seedling root dip followed by soil application of Trichoderma (CT) and Pseudomonas (KP) were significantly superior over other methods in reducing foot rot incidence, besides enhancing seedling growth parameters and grain yield.

Abstract

In India, monsoon failure is experienced in many parts of the state almost every year. Government had implemented various schemes and polices for farmers to cope up with the risk and uncertainty in agriculture due to monsoon failure. The study was conducted in Namakkal district of Tamil Nadu state, with the objective to identify and document extent of awareness and availing of benefits from the Schemes and policies of drought mitigation strategies by the farmers to overcome drought situations. Simple random sampling method was used in selection of 100 farmers each 50 belongs to annual and seasonal crops cultivators respectively. Considering various polices and schemes, the awareness and availing of benefits by farmers were collected and the data were analyzed using percentage analysis. The findings revealed that the extent of awareness of availability of availing benefits from the schemes and polices promoted by the government to mitigate the drought was found to be higher. As more than 75.00 per cent of them express their awareness about the schemes and policies related to drought mitigation. In order to derive benefits from the centrally sponsored schemes like Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) and Pradhan Mantri Fasal Bima Yojana (PMFBY) one has to go through rigorous formalities and procedures within a stipulated time. This might be the reasons that less number of farmers availed benefit from centrally sponsored schemes compared to the state sponsored schemes.

Abstract

Monthly rainfall data for the 14 districts of Kerala from 1985 to 2014 were used in the present analysis to compute the annual and seasonal rainfall. IITM's Sub divisional monthly rainfall data from 1951-2014 has been also used to get a clear picture of the El Niño effect on rainfall variability in Kerala. District-wise area, production and productivity data of two major crops paddy and coconut and state wise area, production and productivity data of other crops such as banana, pepper, tea, coffee, cashew and cardamom is collected from the Directorate of Economics and Statistics, Government of Kerala for the period 1985 to 2014. The weak El Niño was showing a positive influence on the crop yields of coffee, cardamom, banana and cashew, while a negative influence on 2nd and 3rd crop of paddy and tea and neutral effect on coconut and 1st paddy crop. The crop yields of coconut, black pepper, tea, coffee, cardamom, banana, and cashew were negatively influenced by moderate El Niño episodes. The strong El Niño episodes was showing a negative impact on the crop yields of coconut, rice, black pepper, coffee, cardamom and cashew and a positive impact on the crop yields of tea and banana.

Abstract

India ranks second in production of fruit in the world. In traditional harvester (Vedo) mango fruits are harvested by jerk and pulling of the harvester so that fruits get out from the harvester or while detaching a liquid is spread out. This can cause skin or eye injury. More over the traditional harvesting method is time consuming also sometimes harvested fruits may be spilled out of the basket and get damaged due to impact while falling on the ground and only 5 to 7 fruits are harvested because the device needed to be emptied for minimizing the weight on hand. In order to overcome the problem and limitations of the traditional harvesting method (Vedo), a manually operated harvesting device was designed, developed and compared with the traditional harvesting method (Vedo). The harvesting capacities of the developed device and traditional harvesting device were found 73.33 kg/h and 55.00 kg/h up to 3 m of harvesting height and 55.66 kg/h and 44.00 kg/h beyond 3 m of harvesting height respectively. The harvesting losses of the developed device and traditional harvesting device were found 3.5% and 14.90% up to 3 m of harvesting height and 5.41% and 26.60% beyond 3 m of harvesting height respectively. The harvesting cost of the developed device and traditional harvesting device were found 0.43 ₹/kg and 0.57 ₹/kg up to 3 m of harvesting height and 0.57 ₹/kg and 0.72 ₹/kg beyond 3 m of harvesting height respectively.

Abstract

The data of rabi rapeseed mustard yield and weather parameters of twenty five years (1998-2011) were used for the developing the statistical model for the four districts of West Bengal state. The pre-harvest forecasting models were developed for rapeseed mustard yield for Coochbehar, Jalpaiguri, North Dinajpur and South Dinajpur districts respectively. The mean deviation for all the districts for the two years (5.88 and 7.25%) shows over estimation of yield. However, the forecasted yield for 2014 was lower than the average yield of all the districts. The results revels that the lower or higher prediction of yield for rapeseed and mustard was highly influenced by the combination of weather parameters. The lower yield prediction for 2014 for most of the districts may be due to increase in minimum temperature as the model is purely weather based and the minimum temperature has relation with good seed germination.

Abstract

Tomato is a seasonal and highly perishable crop which is preferred for culinary purpose in South India. Due to price volatility, the crop was either un-remunerative to the farmers or unaffordable to the consumers. Hence, this study was conducted to analyze the trend and seasonal variations of tomato prices in selected markets of South India. Time series data on monthly wholesale prices of tomato were used from 2008 to 2017 to study the price variations. The result of linear trend analysis showed that the existence of positive trend in all the selected tomato markets and the price significantly increased over the years. The result of seasonal variations showed that the tomato price reached the peak level during the month of May to July and October to December.

Abstract

Ash gourd, a monotypic genus belongs to the genera Benincasa and one of the long duration crops of Cucurbitace family. In North India, it’s cultivated in river bed system owing to its extensive roots system and a common summer season vegetable. Drought is considered to be more destructive for production of crops compared to other stress. Hence 23 tolerant genotypes were obtained from NBPGR, Thrissur to study the effect of season, genotypes, stress and their interaction during 201718 with regard to biochemical parameters viz. proline content, total phenol content, nitrate reductase activity and catalase activity. From the pooled results it was observed that the proline content increased in stressed condition than non-stressed conditions. The total phenol content ranged between 0.95 to 1.71 mg/100g and 0.63 to 1.41 mg per 100g in stressed and non stressed conditions respectively. The nitrate reductase and catalase activity were found to reduce as the stress increased. The interaction between genotype and stress were non significant in both the seasons indicating the influence of genotype on the expression of these parameters.

Abstract

The present study was undertaken with an aim of understanding mechanism of salinity tolerance in sea shore ecotype of Clerodendrum inerme. In vitro culture of seashore ecotype was carried out using nodal explants, which were inoculated on varied levels of NaCl concentrations (control, 50 mM, 100 mM, 150 mM, 200 mM, 250 mM and 300 mM). The performance of tissue cultured plants was recorded after 20 and 30 days of inoculation, whereas leaf area, leaf thickness and other physiological parameters were recorded after 90 days of inoculation. Salinity stress was found to have significant effect on the shoot length, leaf area and leaf thickness in NaCl stressed plants. Leaf thickness was found to increase in salinity stressed plants. Physiological studies revealed decrease in chlorophyll a/b ratio, total chlorophyll and potassium content in salinity stressed plants. On the other hand, salinity stress had increased proline content, catalase activity and sodium content in the stressed plants. The study revealed that seashore ecotype of C. inerme can grow under in vitro conditions up to 150 mM NaCl, exhibiting morphological and physiological adaptations.

Abstract

The present investigation was conducted in Department of Cotton, Tamil Nadu Agricultural University, TNAU, Coimbatore aiming towards the identification of the extent and nature of association between yield contributing, economically important and fibre quality traits to improve yield and fibre quality in cotton (Gossypium hirsutum L.). In this experiment, 104 genotypes of upland cotton involving both parents and hybrids were studied for correlation and path co-efficient analysis. Eighty four crosses obtained by crossing 12 lines with seven testers in line x tester fashion were evaluated for 16 biometric traits. The outcomes of correlation analysis studies, revealed that single plant yield displayed high significant and positive association with important yield traits such as number of sympodial branches per plant, number of bolls per plant, number of fruiting nodes per plant along with plant height, number of monopodial branches per plant, lint index, ginning out turn and fibre fineness and hence, selection for these characters will help in selecting genotypes with high yield. Based on path analysis, most of the traits expressed both direct and indirect effects on yield, between yield and yield components, which forms the basis for selection of genotypes and high yielding cultivars for an effective crop improvement programme.

Computing the growth of any entity over a time period is important for understanding the past behavior and for future planning. Linear growth rate and compound growth rate are the frequently used methods for calculating the growth rate. The study was carried out using different growth models viz., linear, logarithmic, inverse, quadratic, cubic, compound, S- curve, growth, power and exponential models to project the area, production and productivity of mango crops in Tamil Nadu for the study period 1990-91 to 2016-17. For mango crop the study revealed that through all models exhibited significant; cubic model is the best fitted one because of highest R2, adjusted R2 and least MAPE values. Decreasing trend with respect to mango area and increasing future projection trend with respect to mango production and productivity. Temporal variation within cluster for productivity of mango was 0 to 1 per cent.

Abstract

An experiment was performed in the Laboratory of the Department of Plant Physiology for two consecutive years to study the impact of high night temperature stress in wheat crop with respect to yield attributes and certain biochemical parameters in wheat taking two genotypes viz. HUW-234 (relatively heat tolerant) and Sonalika (relatively heat susceptible). Significant differences were observed with respect to yield attributes where number of ear per plant, number of grain per ear, number of spikelet per ear, test weight, yield and harvest index was found to decrease in the plants kept under stressed condition (25°C/24°C day and night) than those kept under control (25°C/15°C day and night). Similar results were obtained with regard to biochemical parameters such as chlorophyll ‘a’, ‘b’ and total chlorophyll content except for total carotenoid content which showed an increasing trend in response to night temperature stress. In almost all cases, the variety HUW-234 was found to be more tolerant to night temperature stress than the variety Sonalika.

Abstract

Stemphylium blight is one of the most important diseases of onion throughout the world. In view of the destructive nature of the disease, studies were carried out to find the efficacy of various fungitoxicants and bio-agents against the pathogen (S. vesicarium) under in vitro and in vivo. Under in vitro, the maximum inhibition of mycelial growth of test fungus was achieved by Tebuconazole 25.9 EC (98.38%), Captan 50 WP (90.55%) and Trichoderma viride (74.64%), respectively. The treatments found most promising under in vitro studies when tested under field conditions in different combinations, seed treatment and seedling dip with T. viride and two foliar sprays of Tebuconazole 25.9 EC @ 0.05% at 20 days interval starting from the initiation of the disease, proved most effective with least disease incidence (25.44%), intensity (13.43%) and maximum yield (2.9 Kg/plot). Both fungitoxicants and antagonists tested were found effective to reduce disease incidence and intensity, attempt increased the bulb yield over unsprayed control.

Abstract

In this study, mathematical models SRFR 4.06 with zero inertia (ZI) and kinematic wave (KW) model were tested using the data from field experiment from both border and furrow irrigation system. The treatment included were four main treatments of method of Raised bed furrow irrigation M1 (15 cm furrow depth), M2 (20 cm furrow depth), M3 (25 cm furrow depth) and M4 (border irrigation system (control)) under the three sub-treatments of maximum allowable depletion (MAD) T1: Irrigation at 40% MAD, T2: Irrigation at 50% MAD and T3: Irrigation at 60% MAD in four row crop. Zero inertia and kinematic wave model applied to predict advance and recession time in furrow irrigated raised bed system and border and then compared with observed data. Zero inertia and Kinematic wave model under estimated the advance and recession time for furrow irrigated raised bed system and border (λ<1). The average value of slope of best fit line (λ), percentage deviation (PD) and standard error (SE) for predicted and observed advance time were found to be 0.97, 2.35 and 0.028 in zero inertia model and 1.03, 6.24 and 0.14 in kinematic wave model. The zero inertia model gave less percentage deviation and standard error comparison to kinematic wave model. Therefore, zero inertia model is more reliable in predicting advance time in furrow irrigated bed system and border system. The predicted recession time was under estimated by both the models. Zero inertia model predict more reliable results than kinematic wave model.

Abstract

Tasar silkworm host plant is susceptible to variety of insect’s pests. Among all, sucking insects are very dangerous due to their feeding behavior and alteration of nutrition level of host plants, in which tasar silkworm is being reared under field conditions. Field observations revealed that the occurrence of Rhiphiphorothrips cruentatus Hood (Thysanoptera: Thripidae), plant louse, Trioza fletcheri minor Crawford (Hemiptera: Psyllidae), spittlebug, Clovia sp. (Hemiptera: Aphrophoridae) and leaf hoppers (LH), Hishimonus indicus (Sohi) and H. viraktamathi Knight (Hemiptera: Cicadellidae) at Bilaspur region. Random sampling of T. arjuna branches/leaves during July, 2018 revealed that all most all the plants were infested by R. cruentatus, Clovia sp., H. indicus and T. f. minor either alone or in combinations. Mean (±SD) of 11.75±5.30 R. cruentatus, 3.08±2.43 Clovia sp., 15.32±7.03 LH and 19.5±13.40 leaf galls per branch were observed. Detail study on population dynamic of sucking pests in relation to abiotic factors and nutrient status of plant may be studied for better understanding and development of Integrated Sucking-Pests Management practices.

Abstract

Amaranthus polygonides is a leafy vegetable rich in vitamins A and C, propagated through seeds. Seeds are tiny in nature hence separation of empty or immature seeds requires attention for higher productivity. Hence studies were conducted to evaluate the influence of grading on seed quality. Bulk seeds were graded using different BSS wiremesh sieves. The results revealed that size graded seeds retained in BSS 22 × 22 sieve recorded highest seed recovery of 61.6 per cent with higher germination (94%) and vigour index (900) values. Hence, Amaranthus polygonoides var . PLR 1 could be graded using BSS 22 × 22 sieve for obtaining high quality seeds.

Abstract

Formal assessment of the economic impacts of regulation is an increasing component of governments’ desire for evidence-based policy making. In particular in the area of food safety there is a lack of detailed policy guidance for the formal and systematic consideration of the distribution of risks, costs and benefits (environmental, economic and social), and consequently there is a lack of transparency how such considerations are weighed into decision making) Markets work by coordinating the tastes and technology of consumers, producers, middlemen, and sellers given well-established property rights set by government. Markets exist for all types of foods (e.g. burgers, chips, restaurant meals, take away, food ingredients); and markets also exist for gyms, taxis, bicycles, health services, weight-loss clinics, and insurance. Measuring costs and benefits of a policy intervention is easier said than done; by definition there is not a market whereby people demonstrate how much they are willing to pay by buying or not buying a product and whereby firms can respond if their costs are covered. Alternative procedures are needed. Cost–benefit assessment may be applied ex ante to aid the decision whether to introduce a regulation or ex post to determine if it has been successful. Economics makes the point that when markets work, they work well—they lead people to decisions that maximize the benefits to society. If all the key conditions to support a well-functioning market exist, economics tells us markets should be left alone and the final market equilibrium would reflect the best possible outcome for society given the distribution of income. In the SAFE FOODS framework, these correspond to assessment and evaluation; and monitoring, respectively. The ethical matrix could serve to structure the evaluation process. The use of QALYs (Quality Adjusted Life Year) is becoming widely acceptable and either computing the cost per QALY gained from an intervention or using a monetary value for a QALY in cost–benefit analysis are realistic evaluation tools, especially since available secondary sources are now able to relate an increasing number of health states to utility levels. QALYs also benefit from not being biased towards the better off, like traditional willingness to pay approaches.

Abstract

The agricultural sector consumes about 70% of the planet's accessible fresh water more than twice that of industry (23%), and dwarfing municipal use (8%). Many big food producing countries like US, China, India, Pakistan, Australia and Spain have reached, or are close to reaching, their renewable water resource limits. Unsustainable water use harms the environment by changing the water table or depleting ground water supplies. Sustainable management of water in agriculture is critical to increase agricultural production, ensure water can be shared with other users and maintain the environmental and social benefits of water systems. The need is to improve the economic efficiency and environmental effectiveness that seek to improve water resource use efficiency and reduce water pollution from agricultural systems. Excessive irrigation can also increase soil salinity and wash pollutant and sediment into rivers, causing damage to fresh water ecosystems and species as well as those further downstream, including coral reef sand and coastal fish breeding grounds.
