Soil Carbon Sequestration in Conservation Agriculture: A Framework for Valuing Soil Carbon as a Critical Ecosystem Service

/by

Conservation agricultural systems sequester carbon from the atmosphere into long-lived soil organic matter pools – while promoting a healthy environment and enhancing economically sustainable production conditions for farmers throughout the world. Soil organic carbon is fundamental to the development of soil quality and sustainable food production systems. Soil, soil organic carbon, and soil quality are the foundations of human inhabitation of our Earth. We must enhance the ability of soil to sustain our lives by improving soil organic carbon.

Conservation agricultural systems have been successfully developed for many different regions of the world. These systems, however, have not been widely adopted by farmers for political, social and cultural reasons. Through greater adoption of conservation agricultural systems, there is enormous potential to sequester soil organic carbon, which would:

(1) help mitigate greenhouse gas emissions contributing to global warming and

(2) increase soil productivity and avoid further environmental damage from the unsustainable use of inversion tillage systems, which threaten water quality, reduce soil biodiversity, and erode soil around the world.

Wake Up Before It Is Too Late: Make Agriculture Truly Sustainable Now for Food Security in a Changing Climate

/by

Developing and developed countries alike need a paradigm shift in agricultural development: from a “green revolution” to a “truly ecological intensification” approach. This implies a rapid and significant shift from conventional, monoculture-based and high external-input-dependent industrial production towards mosaics of sustainable, regenerative production systems that also considerably improve the productivity of small-scale farmers. We need to see a move from a linear to a holistic approach in agricultural management, which recognizes that a farmer is not only a producer of agricultural goods, but also a manager of an agro-ecological system that provides quite a number of public goods and services (e.g. water, soil, landscape, energy, biodiversity, and recreation) UNCTAD’s Trade and Environment Review 2013 (TER13) contends.

TER13 highlights that the required transformation is much more profound than simply tweaking the existing industrial agricultural system. Rather, what is called for is a better understanding of the multi-functionality of agriculture, its pivotal importance for pro-poor rural development and the significant role it can play in dealing with resource scarcities and in mitigating and adapting to climate change. However, the sheer scale at which modified production methods would have to be adopted, the significant governance issues, the power asymmetries’ problems in food input and output markets as well as the current trade rules for agriculture pose considerable challenges.

TER13, entitled Wake up Before it is Too Late: Make Agriculture Truly Sustainable Now for Food Security in a Changing Climate was released on 18 September 2013. More than 60 international experts have contributed their views to a comprehensive analysis of the challenges and the most suitable strategic approaches for dealing holistically with the inter-related problems of hunger and poverty, rural livelihoods, social and gender inequity, poor health and nutrition, and climate change and environmental sustainability – one of the most interesting and challenging subjects of present development discourse.

Agricultural development, the report underlines, is at a true crossroads. By way of illustration, food prices in the period 2011 to mid-2013 were almost 80% higher than for the period 2003-2008. Global fertilizer use increased by 8 times in the past 40 years, although global cereal production has scarcely doubled at the same time. The growth rates of agricultural productivity have recently declined from 2% to below 1% per annum. The two global environmental limits that have already been crossed (nitrogen contamination of soils and waters and biodiversity loss) were caused by agriculture. GHG emissions from agriculture are not only the single biggest source of global warming in the South, besides the transport sector, they are also the most dynamic. The scale of foreign land acquisitions (often also termed land grabbing) dwarfs the level of Official Development Assistance, the former being 5-10 times higher in value than the latter in recent years.

Regenerative Organic Agriculture and Climate Change: A Down to Earth Solution to Global Warming

/by

We are at the most critical moment in the history of our species, as man-made changes to the climate threaten humanity’s security on Earth. But there is a technology for massive planetary geo-engineering that is tried and tested and available for widespread dissemination right now. It costs little and is adaptable to local contexts the world over. It can be rolled out tomorrow providing multiple benefits beyond climate stabilization.

The solution is farming.

Simply put, we could sequester more than 100% of current annual CO2 emissions with a switch to widely available and inexpensive organic management practices, which we term “regenerative organic agriculture.”
