OBJECTIVE The present study was undertaken to assess the impact of drought on the nutritional status of pre-school children aged 0-5 years from a rural population in a desert area facing drought conditions very frequently. DESIGN The sampling design for assessment was the three-stage sampling technique. SETTING The study was carried out in 24 villages belonging to six tehsils (sub-units of ...

Rising global temperatures in recent years have led to a sharp increase the area of desert areas. Desert areas are widely used as pastures. The productivity pastures Uzbekistan is very low, ie 1-3 ts/ha. This limits year-round use One resource-saving and long-term effective ways their plant enclosures, well reclamation forage rows these using plants such Haloxylon aphyllum , Calligonum caput-me...

With the advent of global energy crisis, use sustainable green has become more and widespread utilization rate photovoltaic industry in high-altitude desert areas is getting higher higher. This article mainly studies intelligent control system area based on microgrid power supply. The uses shielded twisted pair to transmit signals, electrostatic interference electromagnetic induction are effect...

The standard way to measure the air temperature (Ta) as key variable in climate change studies is at 2m height above surface a fixed location (weather station). In contrast, (Ts) can be measured by satellites over large areas. Estimation of Ta from Ts one potential overcoming shortages due uneven or irregular distributions weather stations. However, whether this successful has not been assessed...

/ Large areas of the southern California desert ecosystem have been negatively affected by off-highway vehicle use, overgrazing by domestic livestock, agriculture, urbanization, construction of roads and utility corridors, air pollution, military training exercises, and other activities. Secondary contributions to degradation include the proliferation of exotic plant species and a higher freque...

To understand the adaptive mechanisms, and the strategy and direction of evolution of exploiting plants for living in oasis-desert transitional areas where there was a water gradient, mechanisms of C4 photosynthesis and antioxidative protection were studied in leaves and assimilating shoots of C3 desert shrub Hedysarum scoparium under water gradient accompanied with high irradiance and high tem...

The interaction of wind and water in semiarid and arid areas usually leads to low-frequency flash flood events in desert rivers, which have adverse effects on river systems and ecology. In arid zones, many aeolian dune-fields terminate in stream channels and deliver aeolian sand to the channels. Although aeolian processes are common to many desert rivers, whether the aeolian processes contribut...

Excluding grazers is one of most efficient ways to restore degraded grasslands in desert-steppe communities, but may negatively affect the recovery of plant species diversity. However, diversity differences between grazed and fenced grasslands in desert-steppe are poorly known. In a Stipa breviflora desert steppe community in Northern China, we established six plots to examine spatial patterns ...
