Water Availability, Crop Choices and Profitability of Farming: A Case Study of Mahakanumulla Tank Village

The irregularity in monsoon has severely affected the water availability at surface and sub-surface systems. Diminishing surface and sub-surface availability has not only decreased the water availability, but it additionally affected the ecosystem and increased disastrous situations like floods and droughts, resulting problems of stress on groundwater recharge. Groundwater recharge is a technique by which infiltrated water passes through the unsaturated region of groundwater and joins the water table. It is based upon soil type, land use land cover, geomorphology, geophysical and climate (viz. rainfall, temperature, humidity etc.) characteristics of a region. Over the years, due to variations in weather pattern and overexploitation of aquifers groundwater recharge has decreased and groundwater level has reduced in the most parts of the country. This has led to severe water deficit problems in several parts of the country. This can be solved by different direct and indirect methods of groundwater recharge technology. This technology can reduce the wastage of water and enhance groundwater availability for uses in different sector like irrigation, domestic and industrial uses.

Rule Based

Reservoir operations, especially those which regulate the outflow (release) volume, are crucial for the fulfillment of the purpose to build the reservoir. To get the best results, outflow (release) discharges need to be optimized to meet the objectives of the reservoir operation. A fuzzy rule-based model was used in this study because it can deal with uncertainty constraints and objects without clear or well-defined boundaries. The objective of this study is to determine the maximum total release volume based on water availability (i.e., a monthly release is equal to or more than monthly demand). The case study is located at Darma reservoir. A fuzzy rule-based model was used to optimize the monthly release volume, and the result was compared with that of NLP and the demand. The Sugeno fuzzy method was used to generate fuzzy rules from a given input-output data set that consisted of demand, inflow, storage, and release. The results of this study showed that the release of Sugeno method and the demand have the same basic pattern, in which the release fulfill the demand. The overall result showed that the fuzzy rule-based model with Sugeno method can be used for optimization based on real-life experiences from experts that are used to working in the field.

Estudio De Caso

El municipio de Torre Pacheco ha conocido una significativa evolución en las últimas décadas, tanto desde el punto de vista territorial como socioeconómico. El principal objetivo de esta aportación es comprobar qué tipo de actuaciones han contribuido a modificar la tendencia de declive que compartía con otros espacios rurales. Junto al estudio de caso, se ha recurrido a una metodología no experimental, exploratoria y descriptiva de tipo cualitativo, sin renunciar al soporte de las estadísticas necesarias que cuantifiquen y apoyen determinados aspectos. Los resultados obtenidos ponen de relieve los beneficios alcanzados en Torre Pacheco mediante el incremento de su disponibilidad hídrica, a partir de la aplicación de estrategias de planificación llevadas a cabo con un horizonte temporal de largo plazo.Abstract The municipality of Torre Pacheco has undergone a significant evolution in recent decades, both from the territorial and socioeconomic point of view.

The Tropics

The existence of water as a crop growth requirement is a prerequisite in tropical drylands. In addition, water balance, as an important part of climate change, is needed to be accessed under certain conditions. This study aimed to observe water availability and analyze water balance at drylands for farming planning purposes. The results of this study were then required to determine planting patterns and farming planning in the tropics, in which information related to hydrology is still lack. The Thornthwaite-Mather method approach was used in this study to analyze water balance in areas observed and. Because of its simplicity, this method can also be applied to areas with limited data. The water balance analysis that provides the information on water availability can be used as basic consideration for farming planning, especially at drylands in which water availability is a critical factor for farming activities. In tropical drylands, the cropping pattern of food crops – secondary crops – fallow – horticulture crops can be proposed within farming planning. Maize as a food crop can be planted for the early planting period in January, in which it can be harvested at the age of 80 days around March. In the following month, secondary crops such as soybeans can be planted and harvested at 135 days. Fallow periods during August and September, the lands cannot be optimally used because of water deficit. Entering the beginning of October, the land can be cultivated and prepared for the next crop, eggplant, as horticultural crops, harvested at 135 days in early February.

Annual Discharge

<p>Peak water is a concept that is increasingly used to describe a tipping point in time for glaciated drainage basins, where annual discharge reaches a maximum and thereafter is in continual decline. Millions of people across the globe depend on glacial meltwater, especially in regions such as the Himalayas and the Andes, and therefore current and future changes in meltwater generated flow and downstream water availability are important for society and ecosystem services. Due to the long-term negative consequence of glacier retreat on freshwater resources, peak water in glaciated basins has received more attention in recent years. Using an example case study from the Peruvian Andes, we highlight crucial considerations around scale, process, and terminology when measuring, modelling, and communicating peak water in glaciated basins. Through the application of commonly used peak water calculation methods, we explore the influence of these considerations on the estimation of peak water timing. One such consideration is the processes affecting discharge aside from direct glacial melt, such as catchment storage (aquifers, wetlands, lakes), precipitation, and human activities. In our example case study of the Rio Santa basin in Peru, we find that these factors may all play a much larger role than originally assumed. Subsequently, some peak water estimates may not isolate glacial melt peak water, but instead represent &#8220;basin peak water&#8221;. Depending on the basin of interest, these aspects can play a significant role in water availability, and thus in peak water estimates. We believe that these nuisances are important for ensuring that the peak water concept is appropriately communicated to end-users, and to inform suitable water management. As a scientific community, we now have an opportunity to assess and find ways to move forward with a unified approach to the terminology and communication of peak water.</p>
