Abstract:
Wetlands are abundant across the African continent and provide a range of ecosystem services on different scales but are threatened by overuse and degradation. It is essential that national governments enable and ensure the sustainable use of wetland resources to maintain these services in the long run. As informed management decisions require reliable, up-to-date, and large coverage spatial data, we propose a modular Earth observation-based framework for the geo-localisation and characterization of wetlands in East Africa. In this study, we identify four major challenges in spatial data supported wetland management and present a framework to address them. We then apply the framework comprising Wetland Delineation, Surface Water Occurrence, Land Use/Land Cover classification and Wetland Use Intensity for the whole of Rwanda and evaluate the ability of these layers to meet the identified challenges. The layers’ spatial and temporal characteristics make them combinable and the information content, of each layer alone as well as in combination, renders them useful for different wetland management contexts.

Abstract:
Humans first appeared on the planet about 3.5 million years ago and like most biota, they settled near wetlands because of the availability of food and water. The ancestors of our species understood and knew that water, wetlands, and healthy landscapes were essential for life. In Taiwan, the indigenous people have a long history being a part of and managing the natural resources, including wetlands in their respective habitats. Water and wetlands still play a substantial and significant role in the manner that the Tayal, an indigenous group of people in Taiwan use, preserve, care, protect, respect, and share the habitats and natural resources within which they live. The evolution of Taiwan’s tribal cultures, and probably most cultures on the planet are closely entwined with the resources present in each tribe’s habitat, especially water and wetlands. DNA results indicate 2 lineages of people migrated to Taiwan between 11,000 and 26,000 years ago and gave rise to 9 ethnic groups (Tajima et al. 2003). Today 16 indigenous cultures/tribes are recognized with each occupying different regions of Taiwan’s diverse landscape. Each tribe has its own language and culture and occupies its own geographic region, which contributes to Taiwan’s rich cultural history and diversity. The Tayal tribe is one of the larger tribes with about 88,000 people and the Smangus people are a subset of the Tayal tribe with a culture that is at least 6,000 years old. Culturally, the Tayal people consider themselves to be an element of the environment and their culture is defined by their relationship and interactions with the environment, including all of the other biotic, abiotic elements present in their habitats. In this paper we provide an overview of Tayal culture and philosophy, which determines how the Tayal people manage and protect their natural resources, especially water and wetlands following the tenets of Utux and Gaga that comprise the entirety of their core cultural values. The cultural and language variations, nuances, environmental interpretations, and management techniques are specific to tribal groups and differences in geographic location and environmental settings.

Abstract:
Intensive harvesting of the mangrove crab Ucides cordatus provides subsistence for food and main or additional income to many inhabitants of mangrove areas in Northern Brazil. In order to better understand the spatial patterns of use of this natural resource as basis for sustainable resource-management, we used a combination of GPS-tracking, field observations, semi-structured interviews and participatory mapping with crab-collectors. We quantified daily working hours, traveling distance and time to, as well as collecting time inside, the patches where crabs are collected. Based on preliminary findings for three different types of transportation to the fishing grounds, we conclude that crab-collectors in our study area act in accordance with the central place optimal foraging concept in that they invest more time in traveling to areas with higher catch. We hold these findings will prove relevant for sustainably managing the use of mangrove crabs as natural resource. The parallel occurrence of different collecting-behaviours possibly releases pressure from crab stocks in the potentially depleting fishing grounds adjacent to villages, and thus, may render crab-collecting in these areas more sustainable. Detailed studies are needed to quantify the catch from different mangrove areas and to make these data useful for the sustainable management of natural resource-exploitation in mangroves.
