Rufiji Environment Management Project Rufiji Environment Management Project1 Environmental Management and Biodiversity Conservation of Forests, Woodlands, and Wetlands of the Rufiji Delta and Floodplain An analysis of smallholder opportunities in fisheries, coastal and related enterprises in the floodplain and delta areas of the Rufiji River, Tanzania Richmond, M.D., Wilson, J.D.K., Mgaya, Y.D. & Le Vay, L. Technical report No. 25 February 2002 For more information please contact Project Manager, Rufiji Environment Management Project P O Box 13513 Dar es Salaam, Tanzania. Tel: 44 Utete Rufiji or 2666088 / 0741 322366 Dar es Salaam Email: [email protected] or [email protected] 1 The Rufiji District Council implements Rufiji Environment Management Project with technical assistance from IUCN – The World Conservation Union, and funding from the Royal Netherlands Embassy. Rufiji Environment Management Project – REMP Project Goal: To promote the long-term conservation through ‘wise use’ of the lower Rufiji forests, woodlands and wetlands, such that biodiversity is conserved, critical ecological functions are maintained, renewable natural resources are used sustainably and the livelihoods of the area’s inhabitants are secured and enhanced. Objectives • To promote the integration of environmental conservation and sustainable development through environmental planning within the Rufiji Delta and Floodplain. • To promote the sustainable use of natural resources and enhance the livelihoods of local communities by implementing sustainable pilot development activities based on wise use principles. • To promote awareness of the values of forests, woodlands and wetlands and the importance of wise use at village, district, regional and central government levels, and to influence national policies on natural resource management. Project Area The project area is within Rufiji District in the ecosystems affected by the flooding of the river (floodplain and delta), downstream of the Selous Game Reserve and also including several upland forests of special importance. Project Implementation The project is run from the district Headquarters in Utete by the Rufiji District Administration through a district Environmental Management Team coordinated by the District Executive Director. The Project Manager is employed by the project and two Technical Advisers are employed by IUCN. Project partners, particularly NEMC, the Coast Region, RUBADA, The Royal Netherlands Embassy and the Ministry of Natural Resources and Tourism, collaborate formally through their participation in the Project Steering Committee and also informally. Project Outputs At the end of the first five –year phase (1998-2003) of the project the expected outputs are: An Environmental Management Plan: an integrated plan for the management of the ecosystems (forests, woodlands and wetlands) and natural resources of the project area that has been tested and revised so that it can be assured of success - especially through development hand-in-hand with the District council and the people of Rufiji. Village (or community) Natural Resource Management Plans: These will be produced in pilot villages to facilitate village planning for natural resource management. The project will support the implementation of these plans by researching the legislation, providing training and some support for zoning, mapping and gazettement of reserves. Established Wise Use Activities: These will consist of the successful sustainable development activities that are being tried and tested with pilot village and communities and are shown to be sustainable Key forests will be conserved: Forests in Rufiji District that have shown high levels of plant biodiversity, endemism or other valuable biodiversity characteristics will be conserved by gazettement, forest management for conservation, and /or awareness-raising with their traditional owners. 2 REMP Technical Report 25: Coastal Enterprises Executive Summary Visits were made to the Rufiji District floodplain and delta areas during October and November 2001 to examine aspects of the trade, marketing and preservation of aquatic products, and to consider options for increasing the profitability from aquatic resources. Ten fisheries-related or other potential enterprises that might assist in improving local communities’ profits are considered for piloting in the District. The two main fishery products marketed from the Rufiji District are finfish (both from freshwater and marine sources) and prawns. A specific commercial network governs each product. The prawn fishery supplies an export market via a capitalised structure, and finfish fisheries supply an extensive domestic market, characterised by low individual buying power. The general marketing of aquatic products was found to be similar in structure to that of other small-scale fisheries in East Africa, the sector being characterised by a large number of product-specialised intermediaries with detailed knowledge of particular products and particular markets. The relationships between traders of different levels and between traders and fishers are generally intricate and bonding, the latter improving security of supply for the trader and ensuring both a market and a source of inputs for the fisher. The marketing of other fishery products, presently of considerably less significance than prawns and finfish, are also described. These include the trade in octopus, sea cucumbers, lobsters, freshwater shrimps, sergestid shrimps (‘uduvi’) and mud crabs. Few losses are associated with the prawn fishery since fishers rarely fish when there are no buyers for prawns. Trading losses in finfish are mostly associated with poor quality smoking. The wider availability of ice would have a positive impact on many of the finfish fisheries as well as on trade in prawns. The economic viability of such an enterprise will depend on investment and operation by the private sector. Marine resource management issues pertinent to the Rufiji Delta are highlighted, with a focus on the artisanal prawn fishers and the activities of the industrial fleet of 20 trawlers. The need to incorporate environmental and resource messages in an educational context is discussed and research topics considered to be priorities for the better understanding of the various aquatic resources and their future management are briefly presented. Descriptions are provided on the use of various aquatic resources of the floodplain and delta areas. Future development options are examined, and ways to improve or develop existing enterprises associated with these resources described. The potential to develop small-scale prawn farming in the delta is discussed but not encouraged at this stage. While considering possible enterprises for piloting in the District, the present study focused on the delta area, thus deliberations on the floodplain fishery are based more on brief discussions and the available literature than on field visits. With indications that the floodplain fishery approaches or exceeds the maximum yields no suggestions are made to increase fishing effort in existing water bodies. Instead, a proposal to boost the productivity of the floodplain lakes is provided through the introduction of brushwood enclosures (acadja-enclos). The development of three different freshwater fish culture systems for the floodplains is also described. The first of these is the practice based on excavations of shallow ponds in natural depressions to trap and culture the African air-breathing catfish. The second is tilapia fish farming using ponds and the third is a cross between catfish ponds and tilapia fish culture whereby an extension of existing lakes is dug to trap and culture fish as the lake recedes. The resulting ‘finger ponds’ are then used to grow a mix (or polyculture) of fish with agricultural pursuits on the raised land in between. Recognising that the preservation of fish, and other products, with wood smoke is so vital to the delta i REMP Technical Report 25: Coastal Enterprises and the floodplain, one wide-reaching recommendation is to improve the fish smoking techniques currently in use. Similarly, the fishery for mud crabs already exists but on a small scale. The development and expansion of this fishery is supported. Fishing for large neritic fish species, such as jacks, barracudas, and kingfish is considered under longline fishing gear development. The exploitation and marketing of alternative timbers such as coconut wood is proposed, as is the encouragement of environmental and cultural tourism in the District, particularly in the delta area. Finally, the supply of seafood to the Selous Game Reserve lodges and the description of associative enterprises are synthesised. The final section of this report compares and contrasts the ten potential enterprises described above to determine the “wisest” choices for immediate piloting in the district. The wider application of catfish ponds in the floodplain, the introduction of brushwood enclosures in floodplain lakes, and the development of the delta mud crab fishery were selected for piloting and guidelines for each of these are provided. The importance of the private sector is recognised throughout the study, since without a strong economic incentive, no development is likely to be supported. ii REMP Technical Report 25: Coastal Enterprises Acknowledgements The staff of the REMP are acknowledged for their time and efforts in making the visit to the floodplain and delta so successful. In particular we would like to thank Rose Hogan, Albert J. Mkama,

E-mail: [email protected] Abstract This paper presents the preliminary findings of a WARFSA-funded study, whose objective is to facilitate the formulation of better policies and guidelines for implementing IWRM through case study of local water conflicts. It is observed that, although the current water reforms in the country focus on the use of statutory legal systems to regulate the use of water resources, the country operates under a plural legal system. Apart from the statutory laws, diverse customary systems are relied upon in resolving water-related conflicts, and, neglect of these norms and laws may have negative consequences for the majority of the villagers who rely on them. The paper presents some of the water-related conflicts in the study areas and the views of government authorities and river basin managers regarding customary norms and laws for water resource management. Also, the paper describes how different types of conflicts over water resources are handled through customary, administrative and legal channels. Introduction Water resources management in Tanzania is currently under reform.

  • NOAA's Description of the U.S Commercial Fisheries Including The
    6.0 DESCRIPTION OF THE PELAGIC LONGLINE FISHERY FOR ATLANTIC HMS The HMS FMP provides a thorough description of the U.S. fisheries for Atlantic HMS, including sectors of the pelagic longline fishery. Below is specific information regarding the catch of pelagic longline fishermen in the Gulf of Mexico and off the Southeast coast of the United States. For more detailed information on the fishery, please refer to the HMS FMP. 6.1 Pelagic Longline Gear The U.S. pelagic longline fishery for Atlantic HMS primarily targets swordfish, yellowfin tuna, or bigeye tuna in various areas and seasons. Secondary target species include dolphin, albacore tuna, pelagic sharks including mako, thresher, and porbeagle sharks, as well as several species of large coastal sharks. Although this gear can be modified (i.e., depth of set, hook type, etc.) to target either swordfish, tunas, or sharks, like other hook and line fisheries, it is a multispecies fishery. These fisheries are opportunistic, switching gear style and making subtle changes to the fishing configuration to target the best available economic opportunity of each individual trip. Longline gear sometimes attracts and hooks non-target finfish with no commercial value, as well as species that cannot be retained by commercial fishermen, such as billfish. Pelagic longline gear is composed of several parts. See Figure 6.1. Figure 6.1. Typical U.S. pelagic longline gear. Source: Arocha, 1997. When targeting swordfish, the lines generally are deployed at sunset and hauled in at sunrise to take advantage of the nocturnal near-surface feeding habits of swordfish. In general, longlines targeting tunas are set in the morning, deeper in the water column, and hauled in the evening.

Masija Irrigation Department Ministry of Agriculture, Livestock and Cooperatives P.O. Box 9192 Dar es Salaam Summary Over 1,164,000 ha of wetland areas are listed as suitable for irrigation, mainly for crop production and livestock grazing. Existing and planned irrigation schemes are described for the ,main river basins where large areas are devoted to rice and sugar cane. Emphasis' is placed on the value of small scale, farmer-managed irrigation schemes and the rehabilitation of traditional systems. Introduction All wetlands are potentially suitable for agriculture because of their available water and high soil fertility. Due to national priorities or requirements some wetlands are put to other uses, such as game reserves. The total wetland area identified as suitable for irrigation development is estimated to be over 1,164,600 ha (Table 1). Wetlands are swamps or low lying areas of land which are subject to inundation, usually seasonally. They have hydromorphic soils, transitional morphological characteristics between terrestrial and aquatic ecosystems, and support hydrophytes and halophytes. Wetlands in Tanzania can be characterised under four main categories: 1. Deltaic processes of rivers which discharge into the Indian Ocean and are characterised by flat topography, low lying relief and heavy'clay soils. They are subject to sea water intrusion which contributes to the salinisation of the soils which, under predominantly mangrove vegetation, are potentially acid sulphate.

  • RECREATIONAL FISHING GEAR Setline - Longline
    RECREATIONAL FISHING GEAR Setline - Longline Marker buoys Main line Branch line (snood) Buoy line Hook Anchor weight Gear Description A longline is a setline which is set horizontally on the sea floor. It consists of four main parts; the main line, branch lines (or snoods), hooks and bait. Other components are marker buoys or dhan poles, the buoy line, anchor weights, swivels and clips. The longline is set with an anchor weight at each end. The branch lines are clipped at regular intervals onto the main line. They consist of a shark clip with a short length of braided line tied to a sharp, heavy gauge circle or double hook. Buoy lines and surface marker buoys at each end help the fisher to locate and retrieve the long line. Additional buoys and a dhan pole and flag may also be attached to increase the visibility of the longline for the fisher and other boats. A GPS fix may also assist when locating gear. How it works Longlines are set by attaching snoods to a weighted mainline while the boat is moving so that it lies along the sea floor. As the longline settles on the sea floor, scent from the baits attracts shark and fish to the hooks. Movement of the baits due to the current further entices fish. Squid or octopus tend to be the preferred bait because the leathery texture increases the ability of the bait to stay on the hooks. Fresh scalefish such as jack mackerel and Australian salmon are popular alternative baits.

Tis is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Tanzania is among the countries with the fastest growing economy in Africa and therefore the need for afordable, clean, and most importantly sustainable electrical energy to meet her ever growing demands is pressing. In recent years, the country’s electricity needs have been largely dominated by thermal generations despite the fact that Tanzania is gifed with huge hydropower resource potential approximated at 38,000 MW with only a very small portion exploited to date. However, the exploited potential is expected to grow by commissioning of identifed large and medium-scale hydropower projects with a total installed capacity of 4,765 MW currently under various stages of implementation. Moreover, the geographical location of Tanzania has several benefts to support development of small hydropower projects essential for appropriate utilization of available water resources as a way of mitigating climate challenges efects. Over the last decade, the country electricity demand along with end-use of energy has witnessed signifcant increases as economic development spreads towards achieving Vision 2025 goals.

  • CHAPTER 6 a Tapestry of the Ruvu Past: an Overview to C
    Societies, Religion, and History Rhonda M. Gonzales CHAPTER 6 A Tapestry of the Ruvu Past: An Overview to c. 1800 CE There is no way to recapture the individual voices of Ruvu-speaking peoples who long ago 1 lived in central-east Tanzania. But there is a way to recover the legacies that survive in the words they collectively spoke. This book is the first to bring forth a Ruvu social history using, primarily, reconstructed word histories. Within its pages the histories of the words Ruvu speakers once used are woven into accounts that highlight the ways speakers of proto-Ruvu diverged into many language communities. It also recovers details about how proto-Ruvu and speakers of Ruvu descendant languages lived within their communities in earlier times. The histories of some of those words also permit us to access facets of their speculative knowledge. Working from this tapestry of Ruvu word histories, the book argues that Ruvu people took into consideration foremost in building their communities that the cosmos was biaxial. In their views, people, animals, and the other features found on the earth's surface lived in the cosmos's temporal sphere. The other sphere comprised a world of influential spirits. In Ruvu worldviews, spirits could benefit or hinder peoples' lives and livelihoods. That precept did not determine the way Ruvu people lived, but it did underpin the rationales that legitimized the sociocultural institutions they established in their communities. This chapter is a chronological review of the thematic accounts covered in the foregoing 2 chapters. In previous chapters, a majority of the data were presented along thematic lines because that approach preserved the integrity of the information that Ruvu-speaking consultants shared with me.

  • 1 Chapter 3.1.2: Longline Authors
    3.1.2 LONGLINE CHAPTER 3.1.2: AUTHORS: LAST UPDATE: LONGLINE Domingo A., Forselledo R., Miller March 2014 P., Jiménez S., Mas F. and Pons M. 3.1.2 General description of longline fisheries 1. General description of longline gear and vessels Longline is a fishing gear that is comprised of a main line, with secondary lines attached and hooks placed on the end of them. Longline is a very old gear, derived from “volantín” or “three hook line”, which was used by the Phoenicians and the Egyptians in the Mediterranean Sea (Canterla, 1989). The word “longline” is possibly of Catalonian origin, and derived from southern Italian or Greece (Prat Sabater, 2006; González García, 2008). Since their beginnings and up to the 15th century at least, the longlines that were used were fixed, anchored to the coast with stalks. Later, in the open sea, “jeito” and “vareque” net gears were used which drifted while remaining moored to the vessels, and which could have given rise to drift gears, one of which is longline (Canterla, 1989). 1.a General description of pelagic longline 1.a.1 Introduction Drifting pelagic longline is used worldwide to catch widely distributed pelagic and semi-pelagic fish. This gear is very effective in catching tunas, billfish and sharks, among others (Doumenge, 1998; Matsuda, 1998). It consists of a main line or “mother” line, suspended in the water by secondary lines called float lines, which carry the floats. The branch lines hang from the main line and carry hooks on the ends. The characteristics of the materials, dimensions, types of floats and hooks, as well as the configuration of the lines are quite variable, depending mainly on the origin of the fleets, the fishermen and the target species.
