Ya desde adolescente su vocación por cuidar el suelo era manifiesta. Esa convicción se terminó de forjar y se hizo una forma de vida en la facultad de Agronomía.

“En la época de estudiantes alquilábamos pequeñas parcelas para ensayar la siembra directa en soja de segunda”, recuerda en diálogo con Agrovoz Alejandro Petek: un productor mixto de la zona de Bragado, al oeste de la ciudad de Buenos Aires, donde los suelos arenosos obligan a extremar los cuidados de conservación.

Es por ello que desde 1990 lleva registros continuos de siembra directa en su establecimiento, donde su sueño es poder integrar la agricultura con la ganadería.

Desde abril, Petek es el presidente de la Asociación Argentina de Productores de Siembra Directa (Aapresid), institución que organizó en Córdoba su 26° Congreso Nacional.

–¿Cómo definiría el momento actual de la siembra directa?
–Tiene una trayectoria de crecimiento permanente. El cambio paradigmático que significó comenzar a trabajar con el sistema fue significativo. El productor que la adoptaba rápidamente percibía las mejoras. Así se fueron relacionando y asociando unos con otros y el conocimiento justificó esa decisión. Estamos ahora ante un nuevo punto revolucionario como son los cultivos de servicio, que van a significar una reducción en el uso de agroquímicos y un aumento del ambiente y la fertilidad del suelo. Con la irrupción de una serie de herramientas tecnológicas, como los drones, imágenes satelitales y multiespectrales y sitios específicos, asistimos a otra revolución agronómica. Hay que ver si tenemos la capacidad, el coraje y la visión madura para poder abordarla y responder a ese desafío como lo que somos: líderes mundiales en la siembra directa.

International Symposium in Johannesburg Will Highlight the Role of Soil as the Solution to Food Security and Climate Stability

It all started over lunch during the COP 23 Climate Summit in Bonn, Germany, in November 2017. An idea shared over lunch led to a few back-and-forth emails—and here we are: announcing the “4 per1000 Africa Symposium on Soil for Food Security and Climate.” The Symposium will be held October 24-26 (2018), in Johannesburg, South Africa.

During its third meeting, held in Bonn, the Consortium (governing body) of the French government’s “4 per 1000: Soils for Food Security and Climate” Initiative met to discuss next steps, or as they referred to it, their “Roadmap 2018.” (Never heard of the 4 per 1000 Initiative? Learn more here.) Consortium members highlighted the need to organize regional networks that could draw attention to the global policy initiative, and pressure policymakers to incorporate the initiative’s climate solution into their overall strategy for meeting the goals established by the Paris Climate Agreement.

That’s when I, representing Regeneration International (RI), suggested that we find allies to host an African “4 per 1000” symposium—and now that suggestion has become a reality. We are about to spread the news, to a wide audience in South Africa, about the great potential of regenerative agriculture and land management to heal South Africa’s soils, increase food security in the region, and restore climate stability.

It’s been important for RI to find a platform to bring together players in soil health, food security and climate health. However we also realize the importance and power of partnerships. That’s why we’re thrilled and honored to be organizing this symposium in partnership with the South Africa-based NEPAD Agency, through its Comprehensive Africa Agriculture Development Programme (CAADP), and France’s The 4/1000 Initiative. The timing is perfect for partnering with the NEPAD Agency’s programs—the partnership anchors RI within the CAADP framework which African governments, under the African Union, have signed onto to promote and mainstream the concept of agro-ecological organic regenerative agriculture.

This symposium is much needed at this time, when South Africa, and all of the global south, faces a series of crises. Landscapes are deteriorating every day due to poor management decisions. Year after year, we see a continuous downward spiraling in food security, wildlife habitat, healthy societies and livelihoods.

Small-scale food producers are especially vulnerable to climate disruption, including droughts and flooding. In the restoration of soil carbon, we see tremendous opportunity to build resilience and to not only mitigate, but eventually reverse global warming. What a better way to regenerate both the environment and societies in a continent where agriculture still holds a high place of importance?

The soil is a true ally on the climate crisis front, and Africa has potential to play a big role in this solution journey. Transitioning to regenerative agriculture and land management can help countries fulfill their pledges to meet the United Nations Sustainable Development Goals (SDG) while nourishing the earth and their populations.

The “4 per1000 Africa Symposium on Soil for Food Security and Climate” will be the first event in South Africa dedicated to communicating the message and strategy behind the “4 per 1000” Initiative. The symposium will bring international stakeholders together with international experts and practitioners to engage in an open debate and to share experiences and lessons on the relationship between soil and climate and the benefits of soil health in supporting all forms of life.

Participants will also have the opportunity to learn more about the work and initiatives that are taking place in Africa, including CADDP and African Forest Landscape Restoration Initiative (AFR100), to name a few. We hope the symposium will help build strong support for the “4 per 1000” Initiative and the concept of regenerative agriculture in general.

The symposium is funded in part by RI, NEPAD, the 4 per 1000 Initiative, the German and French governments and registration fees.

Archuleta’s Message Inspires: Get the Ecology Right, the Money Will Follow

Author: Gillian Pomplun | Published: August 8, 2018

Nationally-known soil scientist Ray Archuleta presented a practical road map for restoration of farm profitability to about 200 farmers gathered at the Tainter Creek Watershed Council’s ‘Reducing Costs and Flood Impacts on the Farm’ events.

The program was held Wednesday, July 25 and Thursday, July 26 at Woodhill Farms in rural Vernon County. Tainter Creek Watershed Council members Brian and Laura McCulloh own Woodhill Farms, located in Franklin Township.

The retired 32-year career soil scientist with USDA-NRCS with an ag school background had a straightforward message for the assembled farmers.

“We got it all wrong,” Archuleta was quick to say.  “In our western scientific tradition, we utilize the principle of ‘reductionism,’ which is breaking things down into parts to study them.

Our Turn at This Earth: Could Regenerative Agriculture Save the Ogallala Aquifer?

Author: Julene Bair | Published: August 2, 2018

That’s the question I first asked myself some months ago when I began learning about the Soil Health movement. I’d seen a video of Ray Archuleta, the agronomist who spearheaded the movement, demonstrating how non-tilled versus conventionally farmed soils absorb water. When he placed a clump of soil from a field that had been tilled year after year into a jar of water, it immediately fell apart and turned the water brown, while a clump from a field farmed without tillage held together for over 24 hours. In another test, simulated rain just sat on top of the soil from the tilled field, while it thoroughly saturated the non-tilled soil. Ray attributed these differences to there being more pore spaces in the non-tilled sample.

Excited by the implications for water conservation, I paid a visit to the well-known North Dakota soil health advocate Gabe Brown, who showed me how that porosity occurs. In a field where he’d harvested corn the previous fall, then planted a cover crop of rye and hairy vetch, he pulled a vetch plant from the ground and pointed to chunks of soil that clung to its roots. Plant roots, he explained, secrete what he called exudates, which serve as food for microbes and other soil life, including fungi. The fungi return the favor by exuding glomalin, a sort of biological glue that allows soil to stick together. The resulting chunks of soil, known as aggregates, create the pore spaces that allow water to infiltrate and be retained.

Brent Preston is Farming Sustainably for the Next Generation

In his book ‘The New Farm,’ Preston shares his experience and wisdom for successful organic farming.

Author: Lela Nargi | Published: August 2, 2018

In 2003, Brent Preston and his wife, Gillian Flies, packed up their two kids and moved to a rural town about 100 miles northwest of Toronto. Their initial aim was to live less chaotically and to raise some of their own food. But this morphed into a plan to make a living farming organically.

The inevitable years of mistakes, false starts, financial hardship, emotional and physical exhaustion, scorn from local conventional farmers, perseverance and—at very long last—success, are documented with candor and humor in Preston’s book, The New Farm: Our Ten Years on the Front Lines of the Good Food Revolution, released in the U.S. earlier this year.

Civil Eats talked to Preston about the lessons he and Flies learned from their first decade of rural experience, advice for other well-intentioned (and sometimes naïve) aspiring farmers, and what it might take to bridge the seemingly unbridgeable gap between conventional and organic farming.

Changes in Soil Carbon Stocks Across the Forest-Agroforest-Agriculture/Pasture Continuum in Various Agroecological Regions: A Meta-Analysis

Authors: Nilovna Chatterjee, P.K.Ramachandran Nair, Saptarshi Chakraborty, and Vimala D.Nair | Published: November 1, 2018

The contribution of agroforestry systems (AFS) to enhance soil organic carbon (SOC) storage in soil layers due to the presence of deep tree roots are of interest in the context of promoting carbon sinks and greenhouse gas mitigation. To quantify the relative soil C contribution from trees in agroforestry systems (AFS), this study assessed the reported differences in SOC stocks under agroforestry systems in comparison with other land-use systems (Agriculture, Forestry, Pasture, or Uncultivated Land) in various soil-depth classes in four agroecological regions (arid and semiarid, ASA; lowland humid tropics, LHT; Mediterranean, MED; and temperate, TEM) around the world. Using mixed-effect models and a meta-analytical approach, we synthesized data from 78 peer-reviewed studies that generated 858 data points (sites) on SOC stock under various AFS practiced globally. Comparing Agroforest vs. Agriculture or Agroforest vs. Pasture, SOC stocks under AFS were higher by +27% in the ASA region, +26% in LHT, and +5.8% in TEM, but –5.3% in the TEM in the 0–100 cm soil depth.

6 Reasons Why the Practice of Silvopasture Will Help Save Modern Farming

Author: Steve Gabriel | Published: August 4, 2018

Adapted from “Silvopasture: A Guide to Managing Grazing Animals, Forage Crops, and Trees in a Temperate Farm Ecosystem “(Chelsea Green Publishing, 2018) by Steve Gabriel. All rights reserved.

In addition to the range of benefits silvopasture offers to individual farms, this practice also brings a number of promising benefits to the larger society and global community. These can provide good incentives for government, industry and society to better support and encourage silvopasture as a practice.

1. Wildlife habitat and forest restoration

Farming itself is largely responsible for the fragmented chunks of forest and hedgerows we see littering the rural landscape today. Silvopasture can erase the stark line that is so often drawn between field and forest. Lands lack structural diversity, which is critical for birds and migrating animals. Ideally, we need grasslands, shrublands and deep forests to support the widest range of species. The inclusion of silvopasture into the farm landscape can greatly enhance the structural diversity of vegetation, which in turn supports a greater diversity of wildlife.

Haití, Guatemala y Colombia, clave para reducir el hambre en América Latina

Publicado: 4 de agosto 2018

Publicado por: Noticias ONU

Tres agencias de la ONU se han unido para desarrollar acciones conjuntas en estos países para erradicar la pobreza y el hambre, promover el desarrollo rural y agrícola, y prevenir y gestionar los desastres de origen natural.

El Fondo de la ONU para la Alimentación y la Agricultura (FAO), el Programa Mundial de Alimentos (PMA) y el Fondo Internacional de Desarrollo Agrícola (FIDA) anunciaron que profundizarán su colaboración en América Latina y el Caribe, con un énfasis especial en Haití, Guatemala y Colombia.

El acuerdo regional responde a un acuerdo global entre las agencias de multiplicar esfuerzos para intensificar las acciones de superación de la pobreza y el hambre en el marco de los Objetivos de Desarrollo Sostenible. La alianza busca mejorar la eficacia en el trabajo de las tres agencias, dando una respuesta de mayor calidad a los países y ahorrando los escasos recursos que muchas veces se aplican en gastos duplicados.

“Un tema importante de trabajo es la pobreza rural y el cambio climático. Lamentablemente las comunidades más golpeadas por las consecuencias del cambio climático como inundaciones, sequías, huracanes o incendios están en las zonas más pobres, las zonas de montaña o las comunidades costeras. Entonces necesitamos redoblar los esfuerzos, canalizar más recursos y territorios, repensar las políticas públicas, repensar la institucionalidad y generar nuevas alianzas para llegar con más intensidad a estos territorios”, explica Adoniram Sanches, coordinador regional de programas de la FAO.
