The growth of urban centers in Mexico and the consequent demand for services and overexploitation of their watersheds and aquifers, these being insufficient to cover the demand for drinking water in different cities, and areas with dry climates and poor rainfall are mostly affected. The case study where this research is concentrated is located in the city of Ensenada, where the demand for greater capacity in general basic services such as drinking water supply has created a greater problem when the availability of this resource is very limited by the climatic conditions and the natural environment in arid zones as it is in the North of Baja California. In this research we propose the design and installation of a rainwater collection system, with economic materials and common use that any inhabitant can acquire for their implementation in their own home. In this sense, dissemination has been promoted about the advantages of using natural resources based on collective awareness, emphasizing the scientific dissemination of knowledge. For this last point the moderation of the use of rainwater is made to cover the domestic demand for water through a rain collection system installed in a house of average family. 展开更多

Trees are spread worldwide,as the watchmen that experience the intricate ecological effects caused by various environmental factors.In order to better understand such effects,it is preferential to achieve finely and fully mapped global trees and their environments.For this task,aerial and satellite-based remote sensing(RS)methods have been developed.However,a critical branch regarding the apparent forms of trees has significantly fallen behind due to the technical deficiency found within their globalscale surveying methods.Now,terrestrial laser scanning(TLS),a state-of-the-art RS technology,is useful for the in situ three-dimensional(3D)mapping of trees and their environments.Thus,we proposed co-developing an international TLS network as a macroscale ecotechnology to increase the 3D ecological understanding of global trees.First,we generated the system architecture and tested the available RS models to deepen its ground stakes.Then,we verified the ecotechnology regarding the identification of its theoretical feasibility,a review of its technical preparations,and a case testification based on a prototype we designed.Next,we conducted its functional prospects by previewing its scientific and technical potentials and its functional extensibility.Finally,we summarized its technical and scientific challenges,which can be used as the cutting points to promote the improvement of this technology in future studies.Overall,with the implication of establishing a novel cornerstone-sense ecotechnology,the co-development of an international TLS network can revolutionize the 3D ecological understanding of global trees and create new fields of research from 3D global tree structural ecology to 3D macroecology. 展开更多

L黚ao slow-release water-fertilizer-nutrition agent (LSWA) is a new and proven highly effective soil additive. This nutrient absorbent polymer dramatically conserves water and reduces fertilizer usage while significantly increasing plant and crop yield. There are numerous benefits that LSWA is engineered to produce, and moreover, with every new application new benefits are discovered. The versatility of this additive will undoubtedly lead to some new applications. LSWA crystals in the soil absorb hundreds of times their mass in water and then, upon demand, release the stored moisture regardless of the soil condition. Unlike previously used polymers, LSWA has great absorbability even under soil pressure, and maintains its absorbability in the presence of fertilizers and other water soluble additives. It is completely non-toxic, and has a lengthy effective period of seven to ten years. LSWA is extremely cost effective due to its low initial cost, the dramatic reduction in the number of watering cycles, the decrease of fertilizer usage and the increase in crop yield, as well as allowing utilization of previously unusable land. When LSWA crystals are added into the soil, irrigation schedule times can be reduced by more than 50%, and fertilizer usage reduced by up to 33%. In this paper, some basic researches on the basic properties of the soil additive are reported. Some applications are described by reference to a number of case studies. Finally, specific recommendations are given for the application rates and methods for a range of crops and soil conditions. 展开更多
