Estimating irrigation water amounts for tomato cultivation using observed meteorological data in Djibouti

<p>Irrigation is essential for crop cultivation in dry and semi-arid areas with limited rainfall and water resources. Efficient and effective use of water resources is required but saving irrigation water is important. The study area is in Ali Faren farm located in west of Djibouti which lies in the Horn of Africa. Djibouti is a very dry region with annual rainfall of about 150 mm and an average annual temperature of 28.6°C. Due to such meteorological conditions, water resources depend mostly on groundwater, and this makes water extremely scare. Therefore, water saving in the agricultural field is indispensable.</p><p>This study aims at effective and efficient use of irrigation water in Djibouti. The appropriate irrigation water for tomato cultivation were estimated using CROPWAT provided by FAO and observed meteorological data at Ali Faren farm in Djibouti. The observed meteorological data include air temperature, relative humidity, wind speed and sunshine hour. The conditions required for calculating the amount of irrigation water were medium loam soil texture based on the laboratory results of soil particle size test, and the tomato cultivation period from October to March according to the local farmers.</p><p>The result showed that the average monthly reference evapotranspiration was 5.7 mm/day annually. Reference Evapotranspiration was maximum in July with 7.9 mm/day and minimum in December with 3.9 mm/day. It was observed that the effective rainfall from October to March was 55.2 mm which corresponds to the local tomato cultivation period. Additionally, the required water amount for tomato crops varied between 2.9 to 4.2 mm/day.</p><p>Finally, the appropriate irrigation area of this farm will be determined based on the measured amount of groundwater discharge at an existing well and the estimated irrigation water amount.</p>

Optimization of irrigation depth for mungbean considering the cost for water under a saline condition 査読あり

<p>We have presented a new scheme, “optimized irrigation”, in which irrigation depth is determined such that net income considering the price of water and weather forecasts during each interval is maximized using WASH_1D/2D which are numerical simulation models of water flow and solute transport in soils and crop growth. To evaluate whether the optimized irrigation is also able to restrict salinity stress and avoid salinization without any intentional leaching, we carried out an irrigation experiment.</p><p>Mungbean (<i>Vigna radiata L.</i>) was grown in a greenhouse in Arid Land Research Center, Tottori University, using a drip irrigation system whose emitter distance was 20 cm and lateral spacing was 60 cm. Seeds were sown on May 18 below each emitter after leaching with more than 200 mm. Three treatments were established: 1) irrigation with fresh water (F), 2) irrigation with 1.5 g/L of NaCl solution (C), 3) irrigation with 1.5 g/L of NaCl solution and irrigation depth was determined with the proposed scheme (O). Treatments F and C were irrigated with automated irrigation systems using two tensiometers each installed below 10 cm. Each treatment had three replicates. After June 12, irrigation using the saline water started for treatments C and F. A 2.8 mm of leaching was carried out on July 2.</p><p>Treatment F received the largest amount owing to the largest transpiration rate without any stresses. Treatment C received the lowest amount because of low transpiration rate due to severe salinity stress. We compared net income under producer price of 0.9 $/kg, common miscellaneous costs at 50 $/ha, water price of fresh water at 0.2 $/m<sup>3</sup> and that of saline water 0.1 $/m<sup>3</sup>. Treatment F gained the highest gross income owing to the largest yield (835 kg/ha). Treatment C gained the lowest income and yield (448 kg/ha) while treatment O gained the highest net income owing to lower cost for water than that for F, revealing the effectiveness of the proposed scheme.</p>

Research on solar desalination system and water-saving farming methods for small-scale farmers

<p>In 2017, the United Nations designated 2019 as the “Decade of Family Farming” and requested the promotion of measures and sharing of knowledge related to family farming, which plays a significant role in eradicating poverty and hunger. We are proposing a water-saving farming method for small-scale farmers using a solar-powered desalination system and purified raw water. Desalination plants generally use reverse osmosis membranes, disinfection chemical materials, and consume large amounts of fossil fuels. The solar desalination system we have developed so far is a low-cost, repeatable system that uses the same vacuum heat-absorbing tubes used in solar water heaters. We consider that small-scale farmers are also less burdened by using solar heat, a renewable energy source. The result of calculating the energy conversion efficiency from the measurement of evaporation was 43.9%. Next, water-saving agriculture is so crucial for the efficient use of purified raw water for agriculture. And the water-saving farming method base on the stone mulch farming method, laying bricks on top of root-proof sheets and using localized tillage. The stone-mulch farming method reduces evaporation of water, and the root prevention sheeting relatively reduces competition from weeds. Fertilizer and soil can be added to a locally tilled area to provide intensive nutrition. It also allows for continuous cultivation without removing stones and prevents soil drying and deterioration caused by full tillage. Although in Japan, the experiment of cultivating onions in the open fields using this farming method resulted in nearly double the harvest compared to the conventional method using a tiller.</p><p>In the future, we will develop the technology so that small-scale farmers, such as family farmers, can engage in production by also combining it with drip irrigation. And we will also continue to develop a desalination system using a flat plate heat absorber, which is easier to handle.</p>

<p>We are proposing a water-saving farming method for small-scale farmers using a solar-powered desalination system and purified freshwater. Desalination plants generally use reverse osmosis membranes, disinfection chemical materials, and consume large amounts of fossil fuels. The solar desalination system we have developed so far is a low-cost, repeatable system that uses the same vacuum heat-absorbing tubes and flat plate heat-absorbers used in solar water heaters. We consider that small-scale farmers are also less burdened by using solar heat, a renewable energy source. The result of calculating the energy conversion efficiency from the measurement of evaporation was 30 ~ 46%. Next, water-saving agriculture is so crucial for the efficient use of purified freshwater for agriculture. And the water-saving farming method was based on the stone mulch farming, laying bricks on top of root-prevention sheets and using pit tillage. The stone-mulch farming method reduces evaporation of water, and the root-prevention sheeting relatively reduces competition from weeds. Fertilizer and soil can be added to a locally tilled area to provide intensive nutrition. It also allows for continuous cultivation without removing stones and prevents soil drying and deterioration caused by full tillage.
