Farming with drip sea water irrigation for Salicornia production in Tierra del Fuego, Argentina

Farming for the sustainable production of halophyte crops should begin with the popular knowledge of saline and beneficial plants. On this way, the use of drip irrigation with seawater supply for the production of the halophytic specie Salicornia magellanica was evaluated in a small-scale culture in three growth periods; a randomized design of fifteen plantings were developed in each treatment (n=15), with two irrigation flows in two plant stages (two and seven months of initial pre-planting growth in pots). At the same time, another hydroponic growing experiment was carried out with four different concentrations of seawater (0 – 11 – 20 – 33 g.L of salts) to determine the optimal concentration. The irrigation flow showed different effects on the production parameters and plant age, where the highest yields were recorded in more developed plants in the third season. In the hydroponics with sea water those with low concentration, had a greater and significant values in survival of plants, largest length and number of shoots. These results made it possible to model the consumption of seawater for crops in Tierra del Fuego, Argentina optimizing its use in order to reduce the cost of the provision of seawater for micro crops far from the sea coast.

Algae Spyrogyra hyalina is one species of fresh water algae that is very easy to find in Indonesia. This species of algae known to have a lot of potential, which until now unknown. One potential that tried to explore in this research is the ability of these algae for decreasing the level of salt water salinity into fresh water. This research is an experiment with a completely randomized design (CRD), three treatments and three replications. Testing is done by performing algae arbsorbtion using three forms (powder, granule, and paper) with different biomass (1 g, 2 g, and 4gr). Preparations then coupled into a transparent pipe. The results showed the real effect of the decreased levels of salinity brine through the circuit. Filter with the powder forms with 4gr biomass has the highest salinity level reduction of 15%o, then the dosage form of granules with biomass 4gr with decreased 5.23%o and the third dosage form of paper with 1 gram of biomass with a decrease of 4.23%o.Forms with other biomass have a decrease in the salinity level of not more than 4%o. Preparations with powder form and 4gr biomass can be used to reduce the salinity level in the salt water.

The Cost

The soybean is the main agricultural product produced in Brazil. Among the States, Rio Grande do Sul was the third largest producer in the 2017/2018 harvest. However, insects interfere on the productivity and provide an increase in the cost of production. The velvetbean caterpillar, Anticarsia gemmatalis (Hübner, 1818) (Lepidoptera: Eribidae) is considered one of the main leaf stripper caterpillars. The occurrence can completely fade, reflected in the grain yield. The chemical method is the main control adopted, however, due to the inadequate management of the crop, failures are observed frequently on the field. In this context, the insecticide management is considered an alternative, still little adopted, due to a lack of knowledge between the movement action and the susceptibility of the insect. Therefore, the objective was to evaluate the performance of insecticides used in the soybean crop for the control of A. gemmatalis under laboratory conditions. In the residual and direct contact bioassays, eight treatments with five replicates were used in a completely randomized design, with 2nd and 5th instar caterpillars of A. gemmatalis. The results showed that by residual contact during 24 hours, all the treatments with exception of the control had effectiveness in both instar mortality. The treatments flubendiamide + zeta-cypermethrin and zeta-cypermethrin after four hours application reached 100% of effectiveness. Thus, aiming an integrated pest management program, where it advocated the association of different control tactics, the insecticide management with flubendiamide + zeta-cypermethrin were effective with 100% of control efficiency in both instars.

The Black Sea, surrounded by six riparian countries, is under the threat of severe pollution, giving rise to the need of taking precautions to protect it from further deterioration. In this paper, an effort putting forth a wastewater treatment and management strategy is outlined for the Black Sea coast of Turkey, including both the technical and financial aspects. The present situation of the coast in terms of land-based pollution and infrastructure is stated, followed by an applicable management strategy. The strategy developed for the coastal settlements involves various stagewise treatment schemes based on population distribution and densities along the coastline, and on the availability of land in a specified period of thirty years. Similar strategies are proposed for the control of pollution originating from industries, for those carried by rivers joining the sea, and for leachate of solid waste landfills. The cost estimations of various treatment schemes are also given in terms of population equivalents.

This research aims to create a Reosquido desalination tool for evaporation methods using a microcontroller. This tool can control the temperature to speed up the evaporation process in producing fresh water. The method applied to Reosquido desalination uses Evaporation. The first process before evaporation is the detection of temperature in sea water that will be heated using an element heater. The second process of temperature measurement is to turn off and turn on the Arduino Uno controlled heater, when the temperature is less than 80 ° then the heater is on. The third process is evaporation during temperatures between 80 ° to 100 °, evaporation water sticks to the glass roof which is designed by pyramid. Evaporated water that flows into the reservoir is detected by its solubility TDS value. The fourth process is heater off when the temperature is more than 100 °. Based on the results of the testing, the desalination process using a microcontroller controlled heater can speed up the time up to 55% of the previous desalination process tool, namely manual desalination prsoes without using the heater element controlled by the temperature and controlled by a microcontroller which takes 9 hours. Produces fresh water as much as 30ml from 3000ml of sea water, so that it can be compared to 1: 100.

In this study, two operational methodologies to extract thinned woods were investigated in the Nasunogahara area, Tochigi Prefecture, Japan. Methodology one included manual extraction and light truck transportation. Methodology two included mini-forwarder forwarding and four-ton truck transportation. Furthermore, a newly introduced chipper was investigated. As a result, costs of manual extractions within 10 m and 20 m were JPY942/m3 and JPY1040/m3, respectively. On the other hand, the forwarding cost of the mini-forwarder was JPY499/m3, which was significantly lower than the cost of manual extractions. Transportation costs with light trucks and four-ton trucks were JPY7224/m3 and JPY1298/m3, respectively, with 28 km transportation distances. Chipping operation costs were JPY1036/m3 and JPY1160/m3 with three and two persons, respectively. Finally, the total costs of methodologies one and two from extraction within 20 m to chipping were estimated as JPY9300/m3 and JPY2833/m3, respectively, with 28 km transportation distances and three-person chipping operations (EUR1 = JPY126, as of 12 August 2020).

AbstractSmall-scale commercial rollouts of Cellular-IoT (C-IoT) networks have started globally since last year. However, among the plethora of low power wide area network (LPWAN) technologies, the cost-effectiveness of C-IoT is not certain for IoT service providers, small and greenfield operators. Today, there is no known public framework for the feasibility analysis of IoT communication technologies. Hence, this paper first presents a generic framework to assess the cost structure of cellular and non-cellular LPWAN technologies. Then, we applied the framework in eight deployment scenarios to analyze the prospect of LPWAN technologies like Sigfox, LoRaWAN, NB-IoT, LTE-M, and EC-GSM. We consider the inter-technology interference impact on LoRaWAN and Sigfox scalability. Our results validate that a large rollout with a single technology is not cost-efficient. Also, our analysis suggests the rollout possibility of an IoT communication Technology may not be linear to cost-efficiency.

The Cost

In this study, an inter-continental agricultural pellet supply chain is modeled, and the production cost and price of agricultural pellets are estimated and compared against the recent cost and price of wood pellets in the global marketplace. The inter-continental supply chain is verified and validated using an integration of an interactive mapping application and a simulation platform. The integrated model is applied to a case study in which agricultural pellets are produced in six locations in Canada and shipped and discharged at the three major ports in Western Europe. The cost of agricultural pellets in the six locations is estimated to be in the range of EUR 92–95/tonne (CAD 138–142/tonne), which is comparable with the recent cost of wood pellets produced in small-scale pellet plants (EUR 99–109/tonne). The average agricultural pellet price shipped from the six plants to the three ports in Western Europe is estimated to be in a range of EUR 183–204 (CAD 274–305/tonne), 29–42% more expensive that the average recent price of wood pellets (EUR 143/tonne) at the same ports. There are several potential areas in the agricultural pellet supply chains that can reduce the pellet production and distribution costs in the mid and long terms, making them affordable supplement to the existing wood pellet markets. Potential economic activities generated by the production of pellets in farm communities can be significant. The generated annual revenue in the biomass logistics system in all six locations is estimated to be about CAD 21.80 million. In addition, the logistics equipment fleet needs 176 local operators with a potential annual income of CAD 2.18 million.

Agriculture is the main sources of income for humans. Likewise, agriculture is the backbone of the Indian economy. In India, Tamil Nadu regional state has a wide range of possibilities to produce all varieties of organic products due to its diverse agro-climatic condition. This research aimed to identify the economics and efficiency of organic farming, and the possibilities to reduce farmers’ suicides in the Tamil Nadu region through the organic agriculture concept. The emphasis was on farmers, producers, researchers, and marketers entering the sustainable economy through organic farming by reducing input cost and high profit in cultivation. A survey was conducted to gather data. One way analysis of variance (ANOVA) has been used to test the hypothesis regards the cost and profit of rice production. The results showed that there was a significant difference in profitability between organic and conventional farming methods. It is very transparent that organic farming is the leading concept of sustainable agricultural development with better organic manures that can improve soil fertility, better yield, less input cost and better return than conventional farming. The study suggests that by reducing the cost of cultivation and get a marginal return through organic farming method to poor and small scale farmers will reduce socio-economic problems such as farmers’ suicides in the future of Indian agriculture.
