O antagonismo do modelo de crescimento econômico infinito dentro de um planeta finito, com problemas sociais e ambientais, impõe a necessidade de discussão desse modelo e seus limites, diante do desafio da sustentabilidade. Por essa razão, o presente artigo tem como objetivo abordar tendências agroecológicas na produção agropecuária sob um enfoque de processos sustentáveis. Tratou-se da adubação e da necessidade de recomendações para adubação em sistemas orgânicos e de transição, e dos sistemas agroflorestais e consórcios perenes, como tendências do processo de transição agroecológica. Também foram tratados os temas certificação, organização social, comercialização, assistência técnica e extensão rural, entendendo-os como fundamentais para a promoção dos sistemas agroecológicos.

For this reason, the present article aims to discuss agroecological trends in agricultural production under a sustainable processes approach. In particular, the focus was on fertilization and the need for recommendations for transitional and organic systems, as well as on agroforestry systems and perennial consortium as trends in agroecological transition. Topics such as certification, social organization, marketing, technical assistance and rural extension were also considered as fundamental for the promotion of agroecological systems.

The severe deforestation of Brazil?s Atlantic Forest and the increasing effects of climate change underscore the need to understand how tree species respond to climate and edaphic factors. To identify the most important environmental drivers of coastal Atlantic Forest diversity and functional composition, we studied 42 plots of coastal Atlantic Forest (restinga), which has a high diversity of plant communities and spans strong environmental gradients. We examined how forest physiognomy and functional composition respond to changes in the environment, hydraulic, and soil properties. We tested different hypotheses relating the roles of nutrients and soil water availability in driving shifts in tropical forest diversity and functioning. We collected wood samples and leaves from ~85% of the plant species identified in the forest inventory and estimated the community-weighted tree height, aboveground biomass, basal area of individual plants, specific leaf area, wood density, and the total tree biomass per community by the sum of all trees? aboveground biomass per plot. We measured water table depth and 24 physicochemical soil parameters.
Hypotheses relating to these factors were formalized via both generalized additive models and piecewise structural equation models and null models of community assembly. Increasing drought, as reflected by increasing water table depth, coarse sand, and soil concentration of aluminum (>6 cmol/kg), was found
to be a primary driver of shifts in all measured functional traits. Water table depth was found to be the main environmental driver of restinga species diversity, but shifts in species richness were largely decoupled from functional richness and functional dispersion. Our results suggest that decreases in soil water
availability are a central driver of local phenotype?environment matching and that increasing water limitation increases the role of environmental filtering on multiple traits. Our results show that drought leads to a strong convergence (standardized effect size < 1.95) in forest function and leads to shifts to smaller statured
forest in particular. These findings reveal important differences in the drivers of forest structure and functioning, suggesting that changes in local spatial variation in soil and moisture variables will be a central issue in restinga management and conservation.
