Access and benefit sharing from biological resources and associated traditional knowledge in the HKH region - protecting community interests
After the Convention on Biological Diversity (CBD) came into force in 1993, access to genetic resources, fair and equitable sharing of benefits from the use of biological resources and traditional knowledge become an important agenda. All the Himalayan countries are party to CBD and are in different stages of developing access to genetic resources and benefit sharing (ABS) policies and laws. There are ongoing...

The effect of terracing on rainwater harvesting, regeneration and growth of Juniperusus procera Hochst. ex Endlicher on the Sarawat mountains in south western Saudi Arabia
The present study was conducted in two forests in Abha (Capital of Asir Region) and two forests in Al Namas (130 km north of Abha), south western Saudi Arabia (Asir region) with the objective of investigation of the effect of terraces on rainwater harvesting and growth of Juniperusus procera Hochst. ex Endlicher. Study plots were established in four forests, two of which contained maintained terraces and the...

Invasive alien species in Northern Bangladesh: Identification, inventory and impacts
Identification, inventory and impact assessment of Invasive Alien Species (IAS) in different land use types in five districts of Bangladesh was made. In this extensive survey of more than 100 transects, a total of 21 most abundant species of herbaceous weeds have been recorded. From these, seven invasive alien species, Ageratum conyzoides, Eichhornia crassipes, Eupatorium odoratum, (Chromolaema odorata.) Ipomoea carnea,...

Impact of Ageratum conyzoides L. on the diversity and composition of vegetation in the Shivalik hills of Himachal Pradesh (Northwestern Himalaya), India
The flora of the Shivalik hills of Himachal Pradesh, India is under threat due to the rapid invasion of invasive species. Invasive species means an alien species, which becomes established in natural or semi-natural ecosystems and threatens native biological diversity. In their new regimes they show diverse life forms, habit, morphology, reproductive biology, grow fast, have the ability to grow under...

Present status of Ramsar sites in Nepal
Wetlands cover significant area in Nepal. However, these wetlands are highly under pressure from adverse anthropogenic and natural factors, keeping associated biodiversity under threat. Few wetland inventories have been carried out in Nepal, so the total coverage of wetlands in Nepal is yet to be explored. Nine wetland sites of Nepal are included in Ramsar List till 2009. This article provides a review of...

Tamarinds' (Tamarindus indica L.) niche tree species diversity characterisation reveals conservation needs and strategies
Recently, farmers in East Africa and some other African countries, with technical and research support from government, FAO and World Agroforestry Centre, prioritized tamarind conservation and product development to support livelihood diversification. Just like for most tropical trees; because of past low priority and research neglect, no conservation strategies were yet in place for tamarind. Knowledge on...

Modeling habitat suitability for Grey Crowned-cranes (Balearica regulorum gibbericeps) throughout Uganda
Grey Crowned-cranes occur throughout the mixed wetland-grassland habitats of Eastern and Southern Africa. Due primarily to loss of habitat, however, the species is in swift decline over much of its historic range. We present a prediction of habitat suitability throughout Uganda using a Maxent modeling approach, combining presence-only field data collected over the last few decades (1970 - 2006) with remote...

Mapping the extend of seagrass meadows of Gulf of mannar biosphere reserve, india using IRS ID satellite imagery
Gulf of mannar marine biosphere reserve is the first of its kind in India and also in south east Asia. It extends from Rameswaram in the north to Tuticorin in the south. GOM is having a chain of 21 islands running almost parallel to the mainland. These areas are endowed with a combination of ecosystems including mangroves, seagrasses and coral reefs. Remote sensing techniques offer a wide range of...
