AbstractBiotransformation of organic pollutants is crucial for the dissipation of environmental pollutants. While the roles of microorganisms have been extensively studied, the significant contribution of various root exudates are still not very well understood. Through plant growth experiment, coupled with gas and liquid chromatography-mass spectrometry methods, this study examined the effect of the presence of M. sativa on microbial-associated biochemical transformation of petroleum hydrocarbons.

Improper solid waste disposal practices have negative consequences on the environment and the health of residents. While several factors have been blamed for poor solid waste disposal practices in most developing countries, household socio-economic and housing characteristics have received less attention in the scholarly literature in terms of how they affect residents’ waste disposal practices.

Abstract

The report provides a framework for ensuring that marine spatial planning (MSP) does not worsen poverty and gender inequality in developing countries, and that potentially marginalised groups are appropriately considered and engaged in the MSP process.

This report provides guidelines for the steps of a more inclusive MSP process.

The findings indicate that a scorecard can be used to guide the social sustainability of the MSP process. The criteria in the scorecard include:

The beef production chain in Campeche consists of five links: a) inputs, b) production, c) collection, d) transformation, and e) commercialization. On the other hand, this study reveals a series of bottlenecks and limitations within the sector, which, being a production chain, are more commonly found in the primary links, such as the lack of price regulation, investment, technology, and associativism, among others.

The main outcome of this study reveals that beef cattle activity exhibits the structure of a production chain due to the presence of independent actors, limited contractual relationships, and prioritization of volume - and price-based approaches. However, it does not consider aspects such as the production model or quality. Additionally, it was identified that there is a lack of access to information among the actors in the supply chain, among other factors. 

Using household surveys and spatial geographic data, we are able to control for socioeconomic and geographic characteristics at the individual and census-tract levels. Our results suggest that while payments did not affect poverty rates at the national level, poverty did increase in places where PES had the greatest effect on deforestation. This effect is stronger for uneducated males, who tend to work in agricultural activities.
