Natural resource base degradation, forest denudation, instability in crop production due to scarcity of water necessitates a thorough insight on sustainable agricultural development for conservation of natural resources not only for the present generation but also for the posterity. An attempt had been made to study the natural resource inventory of part of eastern plateau of India, using LISS ...
Singapore, a tropical island of only 716 km2, has substantial land under forest. But rapid urbanisation coupled with the scarcity of land has also resulted in exten‐ sive land clearance. Though highly urbanised, Singapore has managed to retain 4.5% of the land area under nature conservation, and 2.9% under closed forest. Out of four protected areas, two of these, the Central Water Catchment For...
In the case of developing economies, climate change and its economic consequences presume vital importance in the process of realizing sustainable development in the longer timeframe. Land and water are the two major ingredients of the successful realization of this process. It is needless to say that land and water cannot be disconnected while addressing the issue of sustainable development. H...
Bacteria are ubiquitous in the atmosphere, with concentrations of bacterial cells typically exceeding 1×104 m−3 over land. Numerous studies have suggested that the presence of bacteria in the atmosphere may impact cloud development, atmospheric chemistry, and microbial biogeography. A sound knowledge of bacterial concentrations and distributions in the atmosphere is needed to evaluate these cla...
To re-Catholicize Bohemia after the Thirty Years' War, the Austrian Habsburgs commissioned, in 1651, a population list according to religious belief, which generated census-type lists for many communities. A research team is constructing and analyzing a database consisting of the 1651 census, the 1654 tax register, the 1680 tax revisitation, and the 1711-1748 Theresian cadasterfor fivefeudal do...
Soil conservation is the only known way to protect the productive land. In country like Ethiopia, where droughts and floods cause food scarcity problem, soil and water conservation not only increases crop yield, but also prevents further deterioration of land. Soil and water conservation preserve soil moisture and drain water sustainably to avoid soil erosion and depletion of soil nutrients. So...
The world is facing a looming scarcity of land necessary to secure the production agricultural commodities and experiencing competition from other uses [...]
the agriculture sector is the largest water consumer in arid and semi-arid areas. so water scarcity has an important effect on this section. drought as one of the most important factors in making crisis in zayanderud river basin (zrb) has a deep effect on the agriculture sector. this study evaluates the drought effects on irrigation land and farmers profit on the east of zrb by using spi and cb...
Land plants have evolved complex adaptation strategies to survive changes in water status in the environment. Understanding the molecular nature of such adaptive changes allows the development of rapid innovations to improve crop performance. Plant membrane transport systems play a significant role when adjusting to water scarcity. Here we put proteins participating in transmembrane allocations...
