“…Although the species matter to some extent what kind of raw materials can be collected (especially in case of higher value resources), research has shown that for the most crucial NTPF's, such as fuel wood, charcoal and construction material, selection tends not to be very selective. Rather than selecting the most suitable species, people are more likely to make decisions about which ones to harvest based on relative availability, rather than species preference (Walters 2005a). Due to material poverty and dependence on mangrove wood products to meet basic needs, coastal communities often cannot afford to be selective and, instead, will harvest what is most readily available to them (Ewel et al 1998).…”

“…Influenced by this policy, the area of mangrove forests continued to increase in many regions; the government's aim of protecting the environment seems to have been achieved. However, the study of Walters and Vayda finds that in the so-called successful cases, the environmental benefits were not obvious because the planted mangrove forests mainly consisted of a single species that cannot equal the primary forests in function [21,22]. In addition, these single species forests rapidly expanded, resulting in threats and damage to the environment of the primary mangrove forests [23].…”

The Change Mechanism of Human-Environment Interactions from the Perspective of Contextualization: A Case Study of the Honghe Hani Rice Terraces as a World Cultural Heritage Site

Abstract:The importance of special contexts and historical contingency in explaining the mechanism of human-environment interactions is being increasingly emphasized by human geographers. However, their studies lack appropriate theories and an operational framework to apply a "contextualization" epistemology to explain human-environment interactions. Based on the theory of event ecology, this study establishes a new framework and illustrates it by presenting a case study of the world heritage site of the Honghe Hani Rice Terraces (HHRT). This case study demonstrates that in the HHRT, although it is overwhelmingly believed that the sharp increase in the numbers of restaurants and hotels resulted in increased water usage and, consequently, a decreased amount of water for irrigation, in fact, the dry local terraces were mainly caused by continuously decreased precipitation, the planting of water-consuming crops in forests and deforestation in recent years. These factors were not objectively considered primarily because the unbalanced opportunities for residents to participate in tourism led to significant conflicts in the local community. Thus, the locals exaggerated the contribution of tourism to the dry terraces because they wanted the outsiders pay more attention to these conflicts. This study suggests that the new research framework can effectively avoid presupposition and presumption caused by the prior cognition among researchers and local people to objectively recognize the causes of changes in human-environment interactions. In addition, this study demonstrates that it is necessary to analyze the mechanism for changes in human-environment interactions in detail from the perspectives of local political, economic, and social contexts to enhance the sustainable development of cultural landscape heritage sites.

“…Studies focused on these ecosystems as well as the animals highly dependent on them are important to establish programs for their effective and sustainable management (Bacon andAlleng 1992, Farnsworth andEllison 1997). Studies with careful attention to the ecology of human resource use are especially critical in light of the widespread influence of humans on mangrove ecosystems (Walters 2005, Walters et al 2008.…”

The present study was undertaken in two traditional communities that are located on the margins of the estuary and mangrove complex of the Mamanguape River, Paraíba state (PB), Brazil. This work describes the crabs capture techniques tapamento and redinha, and identifies the negative socio-environmental impacts of redinha, using qualitative methods (open and semi-structured interviews, guided tours, direct observation and the administration of questionnaires). Results indicate that currently only two principle techniques are used to capture Ucides cordatus: redinha and tapamento. Tapamento has a low impact in relation to redinha. Redinha was pointed out by interviewees as a system that has social impact (social conflicts, breaking of traditions, substitution and extinction of techniques) and environmental impact (less selective captures and high productivity, mangrove pollution, death of crabs caught in traps, cutting of the roots of Rhizophora mangle, micro-habitat loss resulting from galleries destroyed and polluted). Knowledge of crab harvesting carried out using these two techniques and the possible social and environmental impacts caused by redinha, can lead to more effective planning and actions towards the conservation of the species.
