ABSTRACT In the course of experiments aimed towards the laboratory colonization of Simulium damnosum sensu lato, egg masses of the flies were collected from the field and reared to adults. However, it was observed that with the samples obtained from Boti Falls (River Pawnpawn), the immature stages of S. damnosum were attacked and fed upon by some larvae belonging to the family Chironomidae (Diptera). The presence of two different species of chironomid was suspected because of the occurrence o...

Market Systems of Non-Timber Forest Products (NTFPs) and their Roles in Climate Change Adaptation- A Case Study of the Lawra Distrivt, Ghana

ABSTRACT Local and indigenous communities depend on Non-Timber Forest Products (NTFPs) in a variety of ways. However, the absence of ready markets for these products limits their livelihood support potential and capacity to support environmental and climate change adaptation efforts. This study examined how the five livelihood capitals i.e. Financial, Social, Physical, Natural and Human (including market access, value chain and product quality standards) affect marketing systems for NTFPs an...

Valuation Of The Consumptive And Productive Uses Of Wild And Domesticated Indigenous Leafy Vegetables In Southeastern Nigeria

Abstract Vegetables are grown for human consumption all over the world. Indigenous Leafy Vegetables (ILV), both wild and domesticated species make important contributions to household improvement in Nigeria. However, information on availability of these species in the market and the consumption level at household is limited. Therefore, ILV species in southeastern Nigeria were investigated in order to determine their availability and consumption level. Multi-stage random sampling procedure was...

Silvicultural And Conservation Techniques For Khaya Grandifoliola C. Dc. In Southern Nigeria

ABSTRACT Khaya grandifoliola, an important economic hardwood species, has been severely depleted by overexploitation. This necessitates its ex-situ conservation and requires in-depth knowledge of nursery handlings, seed storage, in-vitro and ex-vitro propagation on which information is sparse. Therefore, silvicultural requirements for conservation and sustainable use of K. grandifoliola in some parts of southern Nigeria were investigated in this study. Seeds of K. grandifoliola were purposive...

Contributions Of Selected Non-Timber Forest Products To Community Livelihoods In Taraba State, Nigeria

ABSTRACT Non-Timber Forest Products (NTFPs) have been identified to contribute to community livelihoods. Such contributions are people as well as site specific and may be shortlived if continuous availability cannot be guaranteed. Information on the role of NTFPs in community livelihoods is crucial to their sustainable management; however, this role has not been properly documented in Taraba State. Therefore, contributions of selected NTFPs to community livelihoods in Taraba State were invest...

Characterisation Of Selected Wood Properties Of Thermal-Modified Bambusa Vulgaris Schrad.Ex J.C.Wendl

ABSTRACT The preservative treatment of non-durable lignocellulosic materials, such as Bambusa vulgaris (bamboo) enhances its service life. Thermally modified lignocellulosic biomaterial is better than chemically treated products because it is environmentally friendly. However, there is a dearth of information on the characterisation properties of thermally modified Bambusa vulgaris. This study was therefore conducted to characterise the properties of thermally modified Bambusa vulgaris. One t...

Models For Growth Characteristics And Their Applications In Yield Studies For Pinus Caribaea Morelet 1851 In Southwestern Nigeria

ABSTRACT Development of empirical models provides ample prospects of exploring established mathematical theories and relationships among tree growth variables for sustainable forest management options. However, there is inadequate information on modelling growth characteristics and productivity potentials of Pinus caribaea, a pulpwood species which is now being proposed for timber production in Nigeria. Hence, models for growth characteristics and their applications in yield studies for Pinus...

Household Coping Strategies For Domestic Energy Price Changes In Northeastern Nigeria

ABSTRACT In Nigeria, high cost of Domestic Energy (DE) has put untold hardship on households. Coping strategy is therefore imperative to meet household domestic cooking and heating needs. Investigating evolving strategies would better inform DE experts and policy makers. This study was therefore designed to investigate strategies devised by households in Northeastern Nigeria for coping with the escalating prices of DE. The domestic energy types considered in the study include Liquefied Natura...

Conflicts Between Forestry And Agricultural Land – Uses In Ogun State

ABSTRACT Clash of interests between custodians of government Forest Reserves (FRs) in Ogun State and farmers operating within them, often results in conflicts causing disruption of socio-economic activities and sometimes loss of lives. Information on the causes and effects of these clashes would better inform policy makers and forestry professionals on workable and sustainable land-use practice. Therefore, factors responsible for such conflicts and their effects were investigated. Seven hundr...

Contribution of Modified Taungya System to Forest Cover And Livelihood of Forest-Fringe Communities. A Case Study of Worobong South Forest Reserve in Ghana

ABSTRACT Decline of natural forest cover through deforestation in Ghana has reached a critical stage. Loss of forest poses many problems, mostly to the communities that rely on the forests for their livelihoods. In the last decade several schemes to protect the remaining forest, restore degraded areas and improve people's access to forest resources have been introduced, of which the Modified Taungya System (MTS), an agro-forestry system, is one of them. The objective of this thesis was to ex...
