The document is a lecture on biogeochemical cycles. It discusses the natural circulation of elements and compounds through both biotic (living) and abiotic (non-living) components of Earth. Elements like carbon, oxygen, nitrogen and water are exchanged between the air, soil, living things and oceans in a continuous movement according to natural laws and processes that maintain life on the planet.

Biogeochemical cycle A Presentation By Mr Allah Dad Khan Former Director General Agriculture Extension KPK Province and Visiting Professor The University of Agriculture Peshawar

This document discusses a method to quantify methane fluxes from local sites using a combination of a tracer release method, Gaussian modeling, and statistical inversion. It finds that using this combined approach provides better estimates than the tracer method alone when the tracer and methane sources are not perfectly collocated or there are multiple methane sources. The combined method is tested on a real farm case study and able to estimate total methane emissions and diagnose some individual facility uncertainties.

FUTURE EARTH Co-producing research to support transformation to sustainability

Integrated Carbon Observation System (ICOS)

This document discusses co-producing research with stakeholders to support sustainability transformations. It defines co-production of research as involving both producers and users of knowledge to develop information that meets user needs and is credible to users. Co-production aims to solve societal problems through genuine change and a mutual learning process. It can lead to impacts like new partnerships, knowledge, and organizational changes. An example project structure involves stakeholders throughout from identifying questions to reviewing results. Future Earth is introduced as an international research initiative that aims to intensify research impact on sustainability through integration, collaboration, and solutions-oriented work on focal challenges like climate change and cities. It operates through national committees, projects, and knowledge networks engaging scientists and stakeholders globally and locally.

Integrated Carbon Observation System (ICOS)

This document summarizes records of CO2, O2 and atmospheric potential oxygen (APO) from two remote sites in Switzerland and France over 10 years. It finds: 1) Trends in CO2, O2 and APO were similar at both sites, increasing by approximately 2 ppm, -20 permeg and -10 permeg respectively per year. 2) Seasonal cycles in the measurements differed between sites, likely due to differences in sampled air masses and fossil fuel influences. 3) Partitioning of atmospheric CO2 among reservoirs estimated from APO data accounted for anthropogenic CO2 emissions but showed some variability between the sites.

This document discusses the cost savings that various companies achieved by switching to more advanced pallet wrapping films and equipment. It provides examples of companies in logistics, food manufacturing, distribution, automotive accessories that reduced the amount of film and number of rolls needed to wrap pallets. This led to annual savings ranging from £4,842 to £20,750 through lower material and labor costs. Improved films allowed pallets to be wrapped more securely using 10-30% less material.
