Climate change adaptation, mitigation and foodsecurity may be addressed at the same time by enhancing soil organic carbon (SOC) sequestration through environmentally sound land management practices. This is promoted by the "4 per 1000" Initiative, a multi-stakeholder platform aiming at increasing SOC storage through sustainable practices. The scientific and technical committee of the Initiative is working to identifyindicators, research priorities and region-specific practices needed for their implementation. The Initiative received its name due to the global importance of soils for climate change, which can be illustrated by a thought experiment showing that an annual growth rate of only 0.4% of the standing global SOC stocks would have the potential to counter balance the current increase in atmospheric CO2. However, there are numerous barriers to the rise in SOC stocks and while SOC sequestration can contribute to partly offsetting greenhouse gas emissions, its main benefits are related to increased soil quality and climate change adaptation. The Initiative provides a collaborative platform for policy makers, practitioners, scientists and stakeholders to engage in finding solutions. Criticism of the Initiative has been related to the poor definition of its numerical target, which was not understood as an aspirational goal. The objective of this paper is to present the aims of the initiative, to discuss critical issues and to present challenges for its implementation. We identify barriers, risks and trade-offs and advocate for collaboration between multiple parties in order to stimulate innovationand to initiate the transition of agricultural systems toward sustainability.

Para conhecer efeito da adubacao nitrogenada sobre o ajuste osmotico em milho e sorgo dois experimentos foram conduzidos em casa de vegetacao, um com milho irrigado em dois niveis de N e outro com sorgo e milho em dois niveis de N, com e sem estresse de agua. Em milho irrigado, folhas saturadas de plantas adubadas com N mostraram potenciais osmoticos 0,1 MPa mais baixos que folhas deficientes em N. Houve correlacao significativa entre as concentracoes de N e acucares nas folhas. Independetemente do regime hidrico, folhas nao-saturadas de plantas de milho adubadas tinham potenciais osmoticos 0,2 MPa mais negativos que folhas deficientes em N. Para o sorgo houve pouca diferenca no potencial osmotico em funcao da adubacao nitrogenada 0,1 MPa. Para as duas plantas, nos tratamentos adubados observou-se transpiracao, por unidade de area foliar, mais elevada, resistencias a difusao de vapor d'agua mais baixas e maior acumulo de solutos e N, em comparacao com folhas deficientes em N. Em condicoes de seca moderada, ou veranicos curtos, plantas bem supridas de N mostraram maior capacidade de ajuste osmotico atraves do acumulo de compostos nitrogenados e outros assimilados. Assim conseguem explorar com maior eficiencia a agua disponivel no solo do que as plantas deficientes em N. |
