Tropical Africa is affected by intense land-use change, particularly forest conversion to agricultural land. In this study, the stream discharge of four small headwater catchments located within an area of 6 km in western Kenya was examined for 2 years (2007 and 2008). The four catchments cover a degradation gradient ranging from intact forest to agricultural land under maize cultivation for 5,...

Since the 19th century, opium has been produced and consumed in the areas of Asia, currently referred to as the Golden Crescent and the Golden Triangle (1). The Golden Crescent lies in South and Southwest Asia, including districts in the Northwest Frontier Province of Pakistan, the adjacent Badakhshan area of Afghanistan and the Baluchistan area of Iran. The area has been the scene of tradition...

Coffee is highly sensitive to temperature and rainfall, making its cultivation vulnerable to geographic shifts in response to a changing climate. This could lead to the establishment of coffee plantations in new areas and potential conflicts with other land covers including natural forest, with consequent implications for biodiversity and ecosystem services. We project areas suitable for future...

Fibroblast cell cultivation method was evaluated by using natural polymers sourced from pulp cellulose in their hydrogel forms. The pulp sourced was offered as an alternative for the preparation of hydrogel films when the cellulose was dissolved in dimethylacetamide/lithium choride (DMAc/LiCl) solution and converted hydrogels having flexible and transparent properties. The cultivation of the fi...

A new automatic stratification method utilizing United States Department of Agriculture (USDA) National Agricultural Statistics Service (NASS) geospatial Cropland Data Layers was recently implemented in NASS operations. Recent research findings indicated that using the automated stratification method significantly improved area sampling frame stratification accuracies in intensively cropped are...

An exotic plant cultural landscape inventory, area wide survey, and natural resource area invasiveness assessment was conducted in 2002 at the Roosevelt-Vanderbilt (ROVA) National Historic Sites (NHS) in Hyde Park, NY. At the species level, 40% of 90 assessed landscape species had not escaped cultivation, 44% had escaped and invaded natural resource areas, and 16% were categorized as migratory ...

Background:Dang gui (Apiaceae; Angelica sinensis radix) is among the most often used Chinese medicinal plants. However, hardly anything is known about its value chain and its influence on the main marker compounds of the drug. The aim of this study is to investigate the value chain of dang gui in Gansu and Yunnan, and the analysis of the marker compounds ferulic acid and Z-ligustilide concentra...

the optimal cropping pattern for sistan water resources management was determined through a goal programming technique within the gams programming environment. results showed that the optimum cultivation area and net profit of the agricultural sector in the sistan region could increase up to 18.1 and 39.8%, respectively, compared to the current status. an increase in the farm irrigation efficie...

parameters recognize different area weather and climatic and effect on the plants one of the best important effect elements is increase products yield. agro climatic study can state area ability and maximum exploit its. the aim of this research is, recognizing of the ability ecologic potential in different areas for cultivating brassica napus in regard to climatic temperature needs in khorasan ...
