“…While the ICLF benefits are reported in the scientific literature, this strategy has not been widely adopted. It is projected that the four modalities of ICLF strategies in Brazil will represent 17.42 million hectares in 2020 (in all the five biomes) [143].…”

The Amazon and the Atlantic Forest are Brazilian biomes that suffered an intense land use and land cover change, marked by the loss of native forest and expansion of agriculture and livestock. This article aims to analyze land use and land cover change history and to propose a sustainable alternative for agriculture and livestock as an opportunity for rural development in these biomes. The statistics of the platform from the Annual Mapping Project for Land Use and Land Cover in Brazil (MapBiomas) were used in an annual historical series from 1985 to 2020. The analysis of land use and land cover changes indicates that the Amazon native forest was reduced by 44.53 million hectares (Mha), while pasture, agriculture and planted forest increased by 38.10, 6.06 and 0.26 Mha, respectively, over the 35 years (1985 to 2020). In the Atlantic Forest, for the same period, forest and pasture reduced by 0.99 and 11.53 Mha, respectively, while agriculture expanded by 8.06 Mha and planted forest by 2.99 Mha. Sustainable land use strategies, such as the Integration Crop-Livestock-Forest (ICLF), can support the increase in agricultural production while recovering and preserving the environment. Policies and programs should consider regional particularities and barriers for more significant adoption of this strategy.

“…Landers, Clay, and Weiss [63] showed a reduced demand for area expansion by land clearing of between 0.8 and 2.5 ha per hectare of LF. As a result of the Landers and Weiss report [64], Brazil set up a subsidized investment credit line for LF and for agroforestry with LF (iCLF), now absorbed in Brazilian Plan for Adaptation and Low Carbon Emission in Agriculture (Brazil's ABC Plan), described by Gurgel and Laurenzana [65] According to estimates of Polidoro and others [66], Brazil has 17.23 Mha of iCLF implanted up to 2021. In the most optimistic scenario, these authors estimate an area of 29.3 Mha by 2030, meaning an annual increase of 1.19 Mha.…”

The origins, history, and recent advances in Conservation Agriculture (CA) are reported. CA is now practiced worldwide on some 200 million hectares, important for mitigating climate change and ensuring food security. Its bedrock is Zero Tillage (ZT) with crop rotation and retention of crop residues. CA approaches Or-19 ganic Agriculture (OA) when coupled to biological control providing opportunity for OA to become truly sustainable. Ley Farming (LF) and agroforestry with ZT are important for carbon sequestration and land use intensification. Hidden cost: each ton of carbon immobilizes 83 kg of N, 29 kg of P, and 14 kg of S. Industry-backed Regenerative Agriculture (RA) variants have no scientific definition, but generally adopt CA. Sustainable, profitable, and compatible new technologies are emerging and CA needs to embrace them to present a holistic, sustainable package to the farmer. How? A single definition for agricultural sustainability via a multi-stakeholder world congress would standardize certification and de-confuse the market. RA describes exactly what CA does for soil health and all farmers need to unite around a new “Combined Regenerative Agriculture” (CRA) to lobby for adequate payments for environmental services. Expansion of CA is critical for world sustainability. Many gaps and constraints exist, especially for smallholders.

“…Two studies provide an analysis of existing policies at national scale, in Brazil (Stuchi et al, 2021) and in Bosnia and Herzogovina Another study from Brazil (Polidoro et al, 2021) analyses the impacts of policies and plans established at the national and regional levels by the Brazilian Government, and the efforts of public and private institutions to encourage farmers to use the practices for controlling soil erosion and toward the massive adoption of zone tillage and conservation agriculture and integrated crop-livestock management systems under conservation agriculture in Brazil.…”

Guest editorial—Policies and practices in action to address soil erosion: A special issue from the Global Symposium on Soil Erosion 2019

This special issue is the second one drawn from the Global Symposium on Soil Erosion (GSER, May 15–17, 2019, Rome, Italy) and includes contributions dealing with the second theme of the GSER: Policies and practices in action to address soil erosion. While there is a good scientific understanding of the physical measures that can be used to prevent or mitigate soil erosion, the main constraints to progress often relate to policy development and or implementation as well as socio‐economic aspects that provide limitations to the implementation of sustainable soil management (SSM) practices including those directed to control erosion. There are no right or wrong answers to which policy or approach is most effective. Some combination of approaches needs to be adopted that work in the particular political, cultural, and socio‐economic environment under consideration. The papers included in this special issue provide examples, from the national to a local level that could be adapted, or used, to improve uptake and implementation of SSM practices to prevent or reduce soil erosion. Regardless of what policy or plan is developed, there has to be effective interaction with the local farmers and land managers as they are the key to implementing any actions that will make a practical difference on the ground. Effective policies cannot be developed or implemented without bringing the land managers ‘on board’ and the needs and limitations of the local farmers must be thoroughly understood and considered in any policy or plan development.
