Does mangrove plantation reduce coastal erosion? Assessment from the west coast of India

Submitted by Vidisha Chowdhury on
EfD Authors:

Mangroves are believed to stabilize the coastlines by controlling erosion and facilitating sediment deposition. Coastal managers often plant mangroves to counter coastal erosion. The state of Gujarat in West India has planted thousands of hectares of mangroves over the years, and control of coastal erosion has been one of the prime reasons of plantation. This study performed a statistical assessment of the effect of the planted mangroves on the coastline changes in the state from 1990 to 2013.

The impact of hermetic storage bag supply and training on food security in Tanzania

Submitted by Salvatory Macha on

Reduction of post-harvest loss (PHL) can play an important role in complementing efforts to address food security challenges. This paper used data from 390 small-scale maize farmers in Kilosa, Tanzania to analyse the impact of post-harvest management training and the supply of hermetic bags on food insecurity status in a framed field experiment setting with two treatments.

A non-parametric statistic for testing conditional heteroscedasticity for unobserved component models

Submitted by César Salazar on
EfD Authors:

When prediction intervals are constructed using unobserved component models (UCM), problems can arise due to the possible existence of components that may or may not be conditionally heteroscedastic. Accurate coverage depends on correctly identifying the source of the heteroscedasticity. Different proposals for testing heteroscedasticity have been applied to UCM; however, in most cases, these procedures are unable to identify the heteroscedastic component correctly.

Network analysis: a novel approach to identify PM2.5 hotspots and their spatio-temporal impact on air quality in Santiago de Chile

Submitted by César Salazar on
EfD Authors:

Air pollution, particularly PM2.5 particulate matter, is a significant issue in Santiago, the capital of Chile. Santiago’s pollution problem is exacerbated by its unique geographic location nestled against the Andes mountain range in the central valley of Chile. This paper uses network models that were developed primarily to analyze systemic risk in the financial system to identify those locations in the city that are most important for explaining PM2.5 levels.
