Cage aquaculture is spreading rapidly on AGLs without lake-specific best management practices (BMPs) to ensure long-term socio-economic and environmental sustainability. PESCA project is developing a decision support tool (DST) and BMPs to guide development or improvement of policies and regulations to improve fish production and profitability from cage aquaculture with minimal impacts on the aquatic environment of the AGLs.
e-CAS is a software developed to manage fish catch and related statistics. The software provides an opportunity for fisheries authorities to engage Beach Management Units in collecting fisheries and related statistics which are then sent by use of mobile phones to a central computer system for processing and utilization. The system increases the frequency of data collection as per the LTA and LVFO standard operating procedure.
The East African Rift System defines the setting of most of Kenya's important internal (e.g., Lakes Nakuru, Naivasha, Baringo, Bogoria) and transboundary (e.g., Lakes Turkana, Victoria) lake basins. The lakes support ecosystems that are rich in birdlife, wildlife and aquatic macrophyte species, but the influent rivers have low species diversity. The lakes and rivers are valuable to the area inhabitants as they provide water and food for humans and livestock, food and nutrition from fisheries, materials for building and weaving, tourism and recreational services, and have aesthetic values.
African Great Lakes (AGLs) contribute 2.7 million tonnes (~25%) to global inland fisheries production (11.9 mt) annually. This is composed of large species (> 20 cm total length, TL) and small pelagic species (< 20 cm, TL). At the turn of the 20th century, fisheries of the AGLs were dominated by large species (tilapine cichlids, Lates spp, cat fishes, Mormyrids, etc.) and management concentrated on these species.
The Metu district is located in the southwestern part of Ethiopia, where the UNESCO registered biosphere is one of the few remnants of natural forest and home of forest coffee Arabica. Over time, the population increased tremendously and over-used the banks the rivers for agriculture severe deforestation and over grazing has completely changed the environment of the district and the Wuchi wetland lost its water and remained bare.
This paper is based on a study that was carried out to investigate the linkages between population dynamics and climate change among both in school and out of school youth aged between 10 and 35 in southern Malawi to inform the development of behavioral change interventions for the PaMawa project. The overall purpose of the project is to promote increased adoption of positive behaviors related to climate change adaptation and sexual reproductive health (SRH) by identifying motivators, barriers and gaps in the uptake of SRH that have a bearing on climate change adaptation.
Tanzania's Northern Lake Nyasa basin contains montane forests that are renowned for their endemic plants and critically endangered fauna (e.g., Kipunji). The region's wetlands are rich in species diversity and among the world's most biologically productive ecosystems. The significant ecosystem services linkages between these areas with downstream aquatic biodiversity, fisheries production, and human well-being, however, receive little attention. The basin's rural human population is expected to grow rapidly, further straining the natural resource base.
There has been a lot of discourse throughout the sustainable development goals (SDGs) process on the need for integrated policies that consider the synergies and trade-off across SDGs thematic areas and how that is critical for the achievement of sustainable development. However, most of the discussions have remained in the global policy arena, with less focus on how the integration would be achieved at national policy and program levels.
Protected areas are often designed around terrestrial conservation priorities, raising questions about their value in conserving aquatic habitats and species. Tanzania's Mahale Mountains National Park represents a unique approach by creating a no-fishing zone along the shore of the largest reserve in the Lake Tanganyika catchment. The objective of this study was to evaluate the benefits of these protections for aquatic habitats, water quality, and littoral fauna.
Lake Chilwa Basin in Southern Malawi has experienced environmental degradation, climate variability and change that have manifested negative impacts on people's livelihoods, food security and health, particularly among the most vulnerable groups such as women and children. However, what has not been established has been the linkages of climate variability and change, and population dynamics particularly migration and public and reproductive health.
Water management needs in the Great Lakes region of Africa are critical, with inadequate institutions, policies and implementation capacity for effective watershed management. As part of a larger Regional Dialogue to Improve Transboundary Water Resources Governance in Africa, United Nations University - Institute for Water, Environment and Health (UNU-INWEH) undertook a comparative study of management approaches by lake commissions in the African Great Lakes and Laurentian Great Lakes in North America.
Fisheries biodiversity and production in Lake Malawi has undergone major changes including the collapse of the chambo and Labeo fishery, the exploitation of the ecologically diverse but specialized mbuna fish for food and the surge in Usipa fish production.
Lake Turkana is Kenya's largest lake, renowned as the world's largest desert lake, with 90% of the lake's inflow provided by Ethiopia's second largest river system, the Omo Basin. The natural hydrological cycle of the Omo / Turkana ecosystem is being dampened by a cascade of major hydropower developments, and in addition, large-scale irrigation plantations downstream will exploit the regulated river flow, and thereby deplete the natural river inflows to the lake. Local people utilize the lake resources, living in harsh conditions.
Anthropogenic pressures pushed the once productive waters of Winam Gulf, in the Kenyan part of Lake Victoria, into a degraded system dominated by nuisance macrophytes (water hyacinths) and blue green algae blooms, affecting water intake, lake transport and logistics, fisheries, hydropower production and tourism. Various donor-driven approaches taken in the past decades to remove water hyacinth were only effective for a limited period of time.
The Health of People & Environment in the Lake Victoria Basin (HoPE-LVB) is a 3-year project in rural areas of the Lake Victoria Basin in Uganda and Kenya that aims to provide underserved families and communities with knowledge and skills to improve reproductive health, reduce levels of poverty through livelihoods_and sustainably manage local natural resources. In 2012, HoPE-LVB conducted a baseline study to inform project design and determine baseline values for key outcome indicators.
This GIS project was completed as part of the Conservation Leadership Programme's (CLP) internship program. CLP supports projects that develop the skills of early career conservationists working to conserve the planet's most threatened species and habitats. This project focused on developing an intern's skills in geospatial mapping analysis, while also supporting the BirdLife Africa Secretariat in this important area of work.
Over 800 million people are malnourished and the global population is growing, and at the current trend 9 out of 10 children living in poverty in 2030 will be from Sub-Saharan Africa. The Sustainable Development Goal (SDG) Zero hunger and the SDG Life below water'promote the conservation and sustainable use of aquatic resources for sustainable development.
The research effort_looks at the trends in fishing effort and landings from 2000 to 2014 in relation to the performance of the Beach Management Units (BMUs) since they were put in place. Having conducted a survey on the performance of the BMUs, researchers notice that the BMUs have rules and regulations that have been put in place. Respondents identified critical habitats that are presented in this research, some of which have since been demarcated. Results show that BMUs know critical habitats and identify them as areas where fish breed (97%).
The fishery activities in Lake Edward are among the major economic activities sustaining livelihoods for the large majority of local communities. In spite of their importance, the conservation and management of critical aquatic habitats is still neglected, leading to alarming rates of decline in fisheries productivity. Growing populations, rapid industrialization and oil exploitation in the region are predicted to exacerbate the pressure on freshwater ecosystems. This requires that appropriate action should be taken for sustainable management of the fishery resources.
A recent expert review of the ecological risks of net pen aquaculture in the North American Great Lakes made a number of recommendations for Best Management Practices (BMPs) that should be applied to establishment of net pen farms. Based on that_study, researchers identified nine generic BMPs that could be applied to all Global Great Lakes.
