“…The human population in the studied area is about 49,000 people with the growth rate of 1.9% per year. There are three major ethnic groups namely Wandengereko, Wamatumbi and Wamakonde living in the area (Nyangoko et al 2020).…”

“…This research found that households of the control site had lower income (159166.67 ± 47162.29) than the income of intervention households (184666.67 ± 59816.19). A study of Nyangoko et al (2022) show that in Rufiji delta, income dynamics are also determined by a number of activities including change in fishing season, cutting and/or selling of mangrove poles and rice farming in the mangrove ecosystem. For instance, the study shows that about 60% of income in the study area was from mangrove-based farming, fishing, and nonmangrove-based crop farming.…”

“…Asian Continent has the largest extent of mangrove ecosystem, accounting for 40% of total global mangrove areas, while Africa accounts for 19% or 3.2 million ha (Friess et al 2019). In East Africa, mangrove ecosystem is a unique type of forest cover, covering about 37% of the entire mangrove on the continent (Ajonina et al 2013) with Tanzania contribute to 14% of all the mangrove ecosystem of East Africa (Nyangoko et al 2020;Japhet et al 2019).…”

“…For instance, Mungai et al (2019), Mshale et al (2017), andAjonina et al (2008) show that in the past 25 years, about 8% of mangrove ecosystem in Eastern Africa covering Kenya, Mozambique, and Tanzania has been lost at an average of 3,000 hectares in a year. The major drivers for mangrove degradation among others in the region are associated with humans as well as natural factors, such as climate change and siltation (Nyangoko et al 2022). Due to this, different practices have been introduced in many mangrove ecosystems worldwide to address the problem of degradation.…”

Abstract. Ngowi NJ, Zakayo G. 2023. Contribution and challenges of mangrove conservation to community’s well-being in eastern Tanzania. Intl J Bonorowo Wetlands 13: 15-21. Several mangrove conservation programs have been implemented in Tanzania to reverse degradation of mangrove ecosystem in the country. However, after their introduction in 1990s, many small-scale farmers relying on the mangrove ecosystems lost their livelihoods. To ensure that the people’s well-being and ecological integrity of the mangrove ecosystem are sustained, this study investigated the impact of nature conservation practices on financial sustainability, food security of local communities as well as ecological integrity of the mangrove ecosystem. The study employed a mixed-method approach where a survey was used to collect quantitative data from 90 household respondents selected randomly for a questionnaire survey. This was supplemented by data collected through personal observations and interviews administered to 30 local people (mainly key informants and focus group discussion). Quantitative data were analyzed through crosstab IBM SPSS version 20. Qualitative data were analyzed using content method. The results indicated that the conservation practices introduced brought a significant difference in financial stability (p<0.05) by increasing incomes of the implementing households to US $80.29 compared to US $69.20 for the non-implementing households. However, 83% of the implementing households still faced food insecurity by having meals only twice daily, although it was slightly higher compared to 80% for the non-implementing households. The 85% of the implementing and 65% of non-implementing households perceived that the conservation practices had improved the ecological integrity of the mangrove ecosystem by increasing the vegetation cover. The results of this study suggest that conservation practices in the mangrove ecosystem have increased financial sustainability and ecological integrity but failed to enhance food security. This study recommends the integration of rights of local communities on usage of land for paddy and fish farming to achieve sustainable economic growth in the estuary.

“…Mangrove forests, known to be important systems of adaption to climate changes, face a number of threats related to climate changes themselves, as well as anthropogenic influences, with repercussions felt at local levels, particularly in developing and underdeveloped countries where people depend directly on natural capital for their livelihoods and well-being (Nyangoko et al 2022). Coastlines are the most densely populated areas on Earth, and the development of coasts is the main driver of mangrove loss worldwide.…”

The restoration of degraded mangrove habitats is a global priority. In countries such as India, the significance of coastal mangrove forests is deeply embedded after the 2004 tsunami and numerous cyclones that caused immense damage to coastal communities. Mangrove restoration drives have been carried out in several regions across the Indian coast. However, the establishment of mangrove nurseries using plastic bags to plant seedlings results in a large amount of plastic waste at the end of each plantation drive. People have tried to combat this issue of plastic pollution by adopting alternative methods but encountered several drawbacks and hitches. In this study, hand‐woven Palmyra (Borassus flabellifer, Arecaceae) bags were experimented with as a replacement for plastic bags to grow seedlings. The bags were able to withstand water inundation conditions similar to those of mangrove tidal flats for a maximum of 6 months, beyond which they disintegrated. The mangrove seedlings showed good growth similar to that in plastic bags, but the roots were well spread in Palmyra bags compared to plastic bags. In addition, during plantation, the seedling along with the bag could be planted as the bags were biodegradable, which is an advantage over plastic bags that need to be removed. Moreover, since local fishermen community members prepared these bags, it provided them with an alternative source of livelihood. Hence, Palmyra bags are an eco‐friendly alternative to plastic bags in reforestation programs.

Sustainable Management of the African Great Lake Coastal Areas: Motivations and Perspectives of Community Citizen Scientists

The long-term sustainability of the African Great Lakes is strongly connected to the management and monitoring of their coastal areas. Yet, the communities that live in these areas are rarely involved in monitoring and have limited influence on key management issues. Furthermore, regulatory activities and knowledge sharing in these transnational ecosystems are strongly limited by funding and infrastructure limitations. Citizen science has great potential to advance both scientific and public understanding of the state of the environment. However, there remains a limited understanding of participants’ motivations and expectations, especially in developing countries, where citizen science has great potential to complement regulatory monitoring. The present study explores the motivations of citizen scientists in villages along Lake Tanganyika’s northern coast and their potential to take a more active role in lake management. Motivations were examined through qualitative interviews, focus groups, and quantitative surveys with 110 citizen scientists and 110 non-citizen scientists from participating villages. Key motivational factors identified were the desire to contribute to scientific research and local knowledge, as well as aspects of financial compensation. The results confirm that participation in citizen science provides many benefits to participants beyond their role as data aggregators and final knowledge users. However, the incentives to participation varied to those typically considered in citizen science programs conducted in developed countries. To create sustainable long-term community based environmental monitoring, these motivations should be incorporated in the program design and participant recruitment.
