Agriculture holdings in Jammu and Kashmir like the rest of country are found in many parcels dispersed in several places all over the village and even sometimes beyond village boundaries. Parcelization of holdings is considered as negatively correlated to productivity. It hampers full and proper utilization of land.

Jim Roberts and colleagues inhaled petrochemical fumes and navigated between ships and oil platforms in order to understand halogen chemistry in the Houston area and along the Texas coast.

Few payment for environmental services (PES) schemes in developing countries operate outside of the central state's umbrella, and are at the same time old enough to allow for a meaningful evaluation. Ecuador has two such decentralised, consolidated experiences: the five-year old Pimampiro municipal watershed-protection scheme and the twelve-year old PROFAFOR carbon-sequestration programme.

Nitryl chloride, an active halogen, can be produced through the night-time reaction of dinitrogen pentoxide with chloride-containing aerosol in the polluted marine boundary, and has been measured at levels that are sufficient to affect the photochemistry of oxidants off the southwestern US coast and near Houston, Texas.

Fisheries form a major source of employment, income and livelihood for most of the people inhabiting the coastal region. Women in fisheries are in general labelled as imperceptible wokers as their contributions are not adequately apprehended and realized. Fishing in India is the main stay of men but women too play a major role in pre and post harvest activities.

On geological timescales, carbon dioxide enters the atmosphere through volcanism and organic matter oxidation and is removed through mineral weathering and carbonate burial. An analysis of ice-core CO2 records and marine carbonate chemistry indicates a tight coupling between these processes during the past 610,000 years, which suggests that a weathering feedback driven by atmospheric CO2 leads to a mass balance between CO2 sources and sinks on long timescales.

Tropospheric ozone contributes significantly to human-induced greenhouse warming. Calculations from satellite measurements of spectral radiance suggest that ozone in the upper troposphere caused an average reduction in clear-sky outgoing long-wave radiation over the oceans of 0.480.14 W m- 2 for the year 2006 between 45
