TL;DR: An assessment of the mitigation potential possible in the AFOLU sector under possible future scenarios in which demand-side measures codeliver to aid food security concludes that while supply-side mitigation measures, such as changes in land management, might either enhance or negatively impact food security, demand- side mitigation measures should benefit both food security and greenhouse gas mitigation.

TL;DR: It is found that although human population has grown fourfold and economic output 17-fold, global HANPP has only doubled, and this result calls for caution in refocusing the energy economy on land-based resources and for strategies that foster the continuation of increases in land-use efficiency without excessively increasing ecological costs of intensification.

TL;DR: It is shown, using state-of-the-art datasets, that vegetation currently stores around 450 petagrams of carbon, in the hypothetical absence of land use, which implies that trade-offs exist between conserving carbon stocks on managed land and raising the contribution of biomass to raw material and energy supply for the mitigation of climate change.

TL;DR: It is shown that about half of all materials extracted globally by humans each year are used to build up or renew in-use stocks of materials, and over this period, global material stocks increased 23-fold, reaching 792 Pg in 2010.

TL;DR: In this article, a comprehensive assessment of global socioeconomic biomass harvest, use and trade for the year 2000 is presented, where the authors developed country-level livestock balances and a consistent set of factors to estimate flows of used biomass not covered by international statistics (eg grazed biomass, crop residues) and indirect flows (i.e., biomass destroyed during harvest but not used).
