Every household always hopes to have enough food available. While fertile agricultural land is decreasing, food needs increase with increasing population. The use of the yard is expected to help improve food availability for the community.In realizing a climate village tourism village in Pandowoharjo Village, a series of activity programs are designed to be carried out continuously for three years. In Year I of the program, community education activities focused on harvesting and using rainwater for vegetable cultivation in the yard. The design of rainwater harvesting facilities is carried out in the form of IPAH, infiltration wells and dead-end channels (Rorak) in six padukuhan which have been designated as the center of tourism village development namely: Brayut, Temon, Pajangan, Dukuh, Karangtanjung and Plalangan.This method of mentoring the PPDM scheme in Pandowoharjo was carried out in three stages, namely program socialization, training and implementation. The mentoring process is carried out with two approaches, namely theoretical training and skills improvement with practice in the field.The results of the activities in Year I of the PPDM program have benefited partners directly, including: a) Increasing number of people who understand, and have skills in responding to climate change; b) Number of facilities for IPAH, infiltration and rorak wells increased by 15 units; c) The number of people who harvest and utilize rainwater increases by 15KK; d) The number of members of the farmer group of women who use the yard for the cultivation of vegetables with vertikulture and hydroponic systems increases by 20 people.Some achievements that are non-physical such as: network of rainwater harvesters, improvement of knowledge and skills of community members, and pilot cooperation partnerships that integrate several productive economic business groups with BUMDes.

Hydroponically planting vegetables is something new for most of the KKNM participants. KKNM activities are carried out for 30 working days based on modules and WhatsApp Group. The vegetable cultivation module with a hydroponic system using used bottles is systematically arranged, equipped with pictures to make it easy for each KKNM participant to implement. WhatsApp Group is used as a means of discussion and consultation. This virtual KKNM activity aims to produce vegetables through a hydroponic system from used bottles and distribute harvested vegetables to the community. The implementation of the activity begins with the preparation of tools and materials, sowing seeds, preparing planting media, maintaining plants, until harvesting. Finally, the distribution of crops to the closest neighbors. The results showed that used plastic bottles can be used as a hydroponic planting medium with the axis system. Transplanting the seedlings to the used wick bottle media that has been filled with nutrients was carried out on the 12th day. Plant maintenance is carried out by periodically controlling the nutritional condition. Harvesting and distribution of vegetables was carried out on the 25th day after transplanting. This Virtual KKNM activity is proven to be able to increase participants' knowledge and skills, and to inspire people to do the same.

ABSTRACT: Salinity is one of the most limiting abiotic stresses in crop production worldwide. In this study, two rocket cultivars (Cultivada and Folha Larga) were grown in hydroponic system (nutrient film technique) under six treatments. The control comprised a nutrient solution without salt addition, and the other treatments contained different NaCl concentrations in the nutrient solution, resulting in the following electrical conductivities: 1.8, 3.8, 5.8, 7.8, 9.7 and 11.8 dS/m. The experimental design was completely randomized (6x2) with six levels of salt and two rockets cultivars, with four replicates per treatment. Increasing salinity reduced the fresh and dry mass of the leaves, roots, and the protein content, but the proline content was increased. The enzymatic activity of catalase (CAT), ascorbate peroxidase (APX) and polyphenoloxidase (PPO) increased with salinity. The activity of CAT and PPO of cv. Folha Larga was higher than of cv. Cultivada and coincided with a greater production of biomass in leaves and roots, showing the effectiveness of the antioxidative defense system in maintaining the growth of genotypes under increasing salinity of the solution.

The World

Research from several regions of the world provides spatially anecdotal evidence to hypothesize which hydrologic and agricultural factors contribute to groundwater vulnerability to nitrate contamination. Analysis of nationally consistent measurements from the U.S. Geological Survey’s NAWQA program confirms these hypotheses for a substantial range of agricultural systems. Shallow unconfined aquifers are most susceptible to nitrate contamination associated with agricultural systems. Alluvial and other unconsolidated aquifers are the most vulnerable and shallow carbonate aquifers provide a substantial but smaller contamination risk. Where any of these aquifers are overlain by permeable soils the risk of contamination is larger. Irrigated systems can compound this vulnerability by increasing leaching facilitated by additional recharge and additional nutrient applications. The agricultural system of corn, soybeans, and hogs produced significantly larger concentrations of groundwater nitrate than all other agricultural systems, although mean nitrate concentrations in counties with dairy, poultry, cattle and grains, and horticulture systems were similar. If trends in the relation between increased fertilizer use and groundwater nitrate in the United States are repeated in other regions of the world, Asia may experience increasing problems because of recent increases in fertilizer use. Groundwater monitoring in Western and Eastern Europe as well as Russia over the next decade may provide data to determine if the trend in increased nitrate contamination can be reversed. If the concentrated livestock trend in the United States is global, it may be accompanied by increasing nitrogen contamination in groundwater. Concentrated livestock provide both point sources in the confinement area and intense non-point sources as fields close to facilities are used for manure disposal. Regions where irrigated cropland is expanding, such as in Asia, may experience the greatest impact of this practice.

ABSTRACT The amount of water and fertilizers used in the production of vegetables, specifically tomatoes, is high. This study was carried out to determine water and fertilizers use efficiency in closed and open hydroponic systems for tomato production under greenhouse conditions. Two treatments with eight replications were assessed; each replication consisted of 67 pots with two plants each. One treatment was a closed hydroponic system (with nutrient solution recirculation), and the other was an open hydroponic system (with non-recirculating nutrient solution). We quantified the amounts of water and fertilizers applied, as well as the losses (drained nutrient solution), in the two treatments during the entire cycle of tomato. In the nutrient solution (NS) we also measured electric conductivity (EC), pH, volume applied, and volume drained, and total weight of fruits (25 pickings). There were no significant differences between the two treatments on fruit production. Water use efficiency was 59.53 kg/fruit/m3 for the closed system and 46.03 kg/fruit/m3 in the open system. In comparison to the open system, the closed system produced 13.50 kg more fruit per cubic meter of water, while 10.31 grams less fertilizers per kilogram of fruit produced were only applied. Water and fertilizers use efficiency were higher in the closed system, by 22.68% and 22.69%, respectively. More efficiency was obtained in the closed system, regarding the open system. We concluded that the closed system is a good alternative to produce tomato and preserve the resources involved in the process (like water and fertilizers), thus reducing pollution.

Vegetable Cultivation

Gending Village is a village located in Gending District, Probolinggo Regency, consisting of 4 Hamlets, 4 RWs, 13 RT. RT 09 area. Buyut Hamlet is one of the areas in the village of Gending, Gending District. The majority of RT 9 residents have livelihoods as farmers. The area of ​​Buyut Hamlet was once a center for catfish farming in the village of Gending, but is now beginning to be abandoned because of the existence of a small amount of feed. The adoption of the budikdamber as the development of the aquaponics system is expected to be able to foster community interest in conducting fish and vegetable cultivation in one place, so that the yields obtained are also abundant and meet the nutritional needs derived from fish and vegetables. One effort to redevelop the local potential in the form of catfish farming, needs to be done an action in the form of socialization. The socialization was carried out by conveying material about hydroponics and buddhambers, which was followed by housewives of RT 9 with the aim to be able to fill spare time and develop the ability of catfish culture that had previously been nurturing, but also as a form of utilization of house yards or narrow land to be efficient and profitable. The practice was carried out by demonstrating the buddhamber accompanied by lecturers and student teams, and handing over the assemblies of the buddambers along with vegetables and fish to one of the residents as a pilot. The results obtained from this program are an increase in knowledge and skills of partners about fish farming in a bucket (Budikdamber) as well as an increase in family food independence by utilizing home yards through the cultivation of vegetables and fish in one place.

Geomorphological Changes

<p>The presence of roads is closely linked with the activation of land degradative phenomena such as landslides. Factors such as ineffective road management and design, local rainfall regimes and specific geomorphological elements actively influence landslides occurrence. In this context, recent developments in digital photogrammetry (e.g. Structure from Motion; SfM) paired with Remotely Piloted Aircraft Systems (RPAS) increase our possibilities to realize low-cost and recurrent topographic surveys. This allows the realization of multi-temporal (hereafter 4D) and high-resolution Digital Elevation Models (DEMs), fundamental to analyse geomorphological features and quantify processes at the fine spatial and temporal resolutions at which they occur. In this research is presented a 4D comparison of geomorphological indicators describing a landslide-prone agricultural system, so as to detect the noticed high-steep slope failures. The possibility to analyse the evolution of landslide geomorphic features in steep agricultural systems through high-resolution and 4D comparison of such indicators is still a challenge to be investigated. In this research, we considered a case study located in the central Italian Alps, where two shallow landslides (L1, L2) were activated below a rural road within a terraced vineyard. The dynamics of the landslides were monitored through the comparison of repeated DEMs (DEM of Difference, i.e. DoD), that reported erosion values of above 20 m<sup>3</sup> and 10 m<sup>3</sup> for the two landslides zones and deposition values of more than 15 m<sup>3</sup> and 9 m<sup>3</sup> respectively. The elaboration of Relative Path Impact Index (RPII) highlighted the role played by the road in the alteration of surface water flow directions. Altered water flows were expressed by values between 2σ and 4σ of RPII close to the collapsed surfaces. The increasing of profile curvature and roughness index described landslides evolution over time. Finally, the multi-temporal comparison of features extraction underlined the geomorphological changes affecting the study area. The computation of the quality index underlined the accuracy of features extraction. This index is expressed in a range between 0 (low accuracy) and 1 (high accuracy) and resulted equal to 0.22 m, regarding the landslide observed during the first RPAS survey (L1-pre); 0.63 m, concerning the same landslide detected during the second RPAS survey (L1-post); 0.69 m for L2. Results prove the usefulness of high-resolution and 4D RPAS-based SfM surveys for the investigation of landslides triggering due to the presence of roads at hillslope scale in agricultural systems. This work could be a useful starting point for further studies of landslide-susceptible zones at a wider scale, to preserve the quality and the productivity of affected agricultural areas.</p>

A small hydroponic system that can use sustainable energy such as solar power has been developed. However, the amount of power generated is not constant, and in the case of unstable weather, enough power cannot be obtained. Therefore, it is necessary to store the generated energy in a battery. In order to design low-cost charging equipment, it is necessary to use a smaller battery and to estimate the remaining charge capacity (state of charge: SOC) accurately. To provide an accurate SOC estimation for such systems, a fusion of CI (current integral) and OCV (open circuit voltage) methods is proposed. When using this method, it is necessary to frequently disconnect the electronic load. In these experiments, the optimum disconnection duration, the effects on plants of frequent battery disconnection, and cutting off of the lighting were investigated.

Sustainability is a topic that is at the center of current discussions in the political, economic, social, and environmental fields. For its analysis, an integral and multidisciplinary vision is needed. This work aims to assess the sustainability of agricultural systems in Paraguay through a comparison applying SAFA (Sustainability Assessment of Food and Agriculture Systems) indicators. The research focuses on 15 case studies on the territory of the Eastern Region of Paraguay divided into five classes of agricultural systems: agribusiness, conventional peasant family farming, agroecological peasant family farming, neo-rural farming, and indigenous agriculture. Data were collected through interviews with producers and key informants, direct observation, and scientific literature research in order to assess, through the SAFA Tool Software, the level of sustainability of each agricultural system as a whole and for each sustainability dimension (political, environmental, economic, and social dimension) in a comparative way. It has emerged that producers belonging to conventional peasant family farming, agroecological peasant family farming, neo-rural farming, and indigenous agriculture have achieved levels of sustainability that are similar to each other and very good in all four dimensions of sustainability. Meanwhile, agribusiness achieved moderate scores in the dimensions of governance and environmental integrity, and was good in the economic and social dimension.
