A key assumption in many homegarden studies is that homegardens are ecologically and socio-economically sustainable due to their species diversity. The precise relation between diversity sustainability still heavily debated, however. basic question how can best be characterized view of the various dimensions variation time space.

ABSTRACT The previously alleged commercialisation-conservation-development links involving non-timber forest products (NTFP) need reconsideration. NTFPs can play an important role in rural livelihood strategies and contribute to sustained forested landscapes various tropical areas, but there is no simple answer how arc livelihoods. emerging picture we describe of a diversified research approach towards NTFP use, with more attention being paid sources other than natural forests the broader...
ABSTRACT Increased attention has been given recently to the role of NTFP's in maintaining rural livelihoods and spiritual roles forests trees for local communities. Few studies have investigated utilitarian cultural an integrated manner. Most focused on indigenous communities with little biodiversity living under non-traditional conditions. Furthermore most research focussed extraction resources tropical rain only attempts made determine contribution temperate-zone vegetation types. The aim...

Biocultural diversity, which refers to the inextricable link between biodiversity and cultural has been predominantly associated with traditional ways in indigenous people tropical countries interact natural environment. But it does not have be restricted these circumstances. diversity may also regarded as an interesting concept for understanding how industrialized globalized societies deal nature.

Abstract Measurements are reported of rainfall, throughfall, stemflow, and derived interception losses made on a daily basis during two consecutive rainy seasons in 4–5 year old rapidly growing plantation forest Acacia auriculiformis humid tropical environment. During the first observation period loss amounted to respectively 81, 8, 11 per cent gross precipitation, whilst corresponding values for second were 75, 7, 18 cent. All three components correlated strongly with amounts but slopes...
Non-timber forest product (NTFP) governance is a recent concept denoting the process of rule and decision-making concerning production marketing. This paper reviews multiple dimensions trends in NTFP governance. It emphasises that more than rule-making includes broader societal based on social practices, values principles. characterised by coexistence formal informal institutions plural statutory, customary market norms; combination forestry agrarian regimes; multilevel multi-actor...
