Savitribai Phule Pune University is known for its biodiversity in Pune. In the present study, we have analyzed changes which occurred on campus and surrounding area over last 40 years. Of 90 bird species reported Khadki pond 1976, failed to notice 34 2018. A major reason decline diversity could be habitat from low scrub jungle, fallow lands grassland buildings, roads, exotic plantations. Increa...
Clearing forests for swidden agriculture, despite providing food to millions of farmers in the tropics, can be a major driver deforestation. Payments ecosystem services schemes help stop agriculture-induced forest loss by rewarding users maintaining forests. Clear and secure property rights are key prerequisite success these payment schemes. In this study, we use novel iterative dynamic game Ma...
Integrating Sheep Grazing into Cereal-Based Crop Rotations: Spring Wheat Yields and Weed Communities
Crop diversification and integration of livestock into cropping systems may improve the economic and environmental sustainability of agricultural systems. However, few studies have examined the integration of these practices in the semiarid areas of the Northern Great Plains (NGP). A 3-yr experiment was conducted near Bozeman, MT, to compare the effects of crop rotation diversity and weed manag...
Fatty acid methyl esters (FAMEs) were used to `®ngerprint' soil microbial communities that evolved during 25 years of wheat-fallow cropping following native mixed prairie sod at Sidney, Nebraska, USA. Total ester-linked FAMEs (EL-FAMEs) and phospholipid-linked FAMEs (PL-FAMEs) were compared for their ability to discriminate between plots remaining in sod and those cropped to wheat or left fallo...
Authors consider the development of virgin and fallow lands in Kazakhstan 1950s–1960s which led to an unprecedented anthropogenic intrusion into environment. The huge concentration people northern steppe regions spread dangerous infectious diseases among diphtheria was particular concern health authorities republic. made attempt analyze issues this disease Tselinny district early 1960s history ...
The article examines the outbreak of infectious hepatitis and typhoid fever in 1964 city Tselinograd. During development virgin fallow lands a large number people arrived northern Kazakhstan. urban infrastructure that existed at time was not always able to provide population with necessary services, which often led failure emergence difficult epidemiological situation. On basis statistical mate...
The efficacy of clean fallow, bermudagrass (Cynodon dactylon) as a rotational crop, and fenamiphos for control of root-knot nematode (Meloidogyne incognita race 1) and soilborne fungi in okra (Hibiscus esculentus), snapbean (Phaseolus vulgaris), and pepper (Capsicum annuum) production was evaluated in field tests from 1993 to 1995. Numbers of M. incognita in the soil and root-gall indices were ...
One hundred and nine soil samples were collected in 69 different localities along two transects, one North– South, about 900 km in length, and the other East–West (750 km in length), across Senegal and Gambia. The first transect followed a rainfall gradient and the second a human density gradient. The relationship between carbon content, C/N ratio and soil type on the abundance and species dist...
A pilot cropland carbon sequestration program within north central Montana has allowed farmers to receive carbon credit for management adjustments associated with changing from tillage-based agricultural systems to no-till. Carbon credit can also be obtained by adopting conservation reserve, where cropland is planted into perennial vegetation. Summer fallowing is also considered within the cred...
