Valuation of Ecosystem Services and Strategic Environmental Assessment Influential Case Studies
Cover page: Ecosystem services around the world Top right: Pantanal, Brasil: the world’s largest freshwater wetland, is a paradise for bird photographers. Nature tourism is booming in the area. Left: Kerala, India: the Kuttanad backwaters are protected from storm surges by a coastal belt of coconut trees. The coconuts provide fiber for a large coir industry. The backwaters provide the only means of transport in the area. Centre: Benue valley, Cameroon: in rural Africa wood still is the main source of energy. When resources suffer from overexploitation, women (and children) have to walk ever- increasing distances to collect firewood. Bottom right: Madeira, Portugal: often referred to as the island of flowers, here sold on the local market.

Today, this network counts 610 sites in 117 countries across the world, stretching from terrestrial to coastal and marine ecosystems, from high mountain peaks to deep ocean abysses. In Sub-Saharan Africa, there are 64 biosphere reserves in 28 countries. This publication provides an overview of the unique role of biosphere reserves for sus- tainable development and nature conservation in the continent. African countries implemented this concept very early as soon as 1976 when the first sites were rec- ognized. -
(Japanese Barnyard Millet) and E. Frumentacea (Indian Barnyard Millet) – a New Avenue for Genetic Enhancement of Barnyard Millet
Electronic Journal of Plant Breeding, 5(2): 248-253 (June 2014) ISSN 0975-928X Research Note Interspecific Hybrid between Echinochloa esculenta (Japanese barnyard millet) and E. frumentacea (Indian barnyard millet) – A New Avenue for Genetic Enhancement of Barnyard Millet Salej Sood*, R. K. Khulbe, Navinder Saini1, Arun Gupta2 and P. K. Agrawal Vivekananda Parvatiya Krishi Anusandhan Sansthan (ICAR), Almora, 263601- Uttarakhand, India Present Address:1Indian Agricultural Research Institute, New Delhi, India 2Directorate of Wheat Research, Karnal, India Email: [email protected] (Received: 15 Apr 2014; Accepted:28 Apr 2014 ) Abstract Inter-specific hybridization between the two cultivated species of barnyard millet, Echinochloa frumentacea (Indian barnyard millet) and E. esculenta (Japanese barnyard millet) holds enormous potential for their mutual genetic enhancement. Here, we report the success in obtaining inter-specific hybrid between E. esculenta and E. frumentacea involving cultivars PRJ 1 and ER 72 of the two species, respectively. The hybridity of F1 plants was confirmed through rice SSR (Simple Sequence Repeat) markers. The hybrid plants of the cross PRJ 1 x ER 72 were vigorous, heavily tillered with high culm branching and were free from grain smut disease but failed to set seed due to sterility. Successful hybridization between the two species opens up vast avenues for introgression of desirable traits and exploitation of genetic variability present in the two species for their mutual genetic improvement, besides a wide array of conventional and genomic researches particularly dissection of traits such as yield and disease resistance. Key words: Barnyard millet, hybrid sterility, SSR cross-transferability Barnyard millet (Echinochloa spp.) is one of the in the states of Uttarakhand, Madhya Pradesh, oldest domesticated millets in the semi-arid tropics Karnataka, Uttar Pradesh and North east region of of Asia and Africa. -

When we were given the opportunity to conduct The baseline study for Thane creek” we felt blessed to learn more about this unique ecosystem the largest creek from asia. This study was possible due to Mr. N Vasudevan, IFS, CCF, Mangrove cell, Maharashtra whose vision for the mangrove habitats in Maharashtra has furthered the cause of conservation. Hence, we thank him for giving us this opportunity to be a part of his larger goal. The present study involved interactions with a number of research institutions, educational institutions, NGO’s and community, all of whom were cooperative in sharing information and helped us. Most important was the cooperation of librarians from all the institutions who went out of their way in our literature survey. -
Gambaga Flycatcher Muscicapa Gambagae: Evidence for Migration in West Africa?
Volker Salewski et al. 48 Bull B.O.C. 2003 123(1) Gambaga Flycatcher Muscicapa gambagae: evidence for migration in West Africa? by Volker Salewski, Karl H. Falk, Franz Bairlein & Bernd Leisler Received 21 December 2001 Despite reviews by Elgood et al. (1973) for Nigeria and Curry-Lindahl (1981) for Africa, knowledge of intra- African migration systems remains poor. The Gambaga Flycatcher Muscicapa gambagae is thought to be migratory (Urban et al. 1997). It has a disjunct distribution from Mali and Ivory Coast in the west to Somalia and south-west Arabia in the east, and Zaire and Kenya in the south (Urban et al. 1997). In West Africa it is claimed to be resident in Liberia, Ivory Coast, Ghana, Togo and Nigeria (Dowsett & Forbes-Watson 1993), a non-breeding migrant in Mali from August to December, presumably breeding further south in March and April (Urban et al. 1997) and moving northwards with the rains (Lamarche 1981). It has been recorded as a vagrant in Burkina Faso (Holyoak & Seddon 1989) and was recently recorded from Guinea (Nikolaus 2000). Borrow & Demey (2001) described its status as a rare to scarce resident and partial migrant in the above-mentioned countries. In East Africa it is also thought to be a partial migrant based on the mist-netting of 3 juveniles at night at Ngulia, Kenya, presumably on migration, and on the fact that all East African records south of 7°N are from November to April (Urban et al. 1997). Breeding has been recorded in Kenya in March (Richards 1992) and in south- west Arabia in June (Castell et al. -

Ghana Mega Rockfowl & Upper Guinea Specials 3 to 25 January 2016 (23 Days) Trip Report
Knox Ghana Mega Rockfowl & Upper Guinea Specials 3 to 25 January 2016 (23 days) Trip Report Akun Eagle-Owl by David Hoddinott Trip Report compiled by Tour Leader Markus Lilje RBT Knox Ghana Mega Trip Report January 2015 2 Trip Summary Our private Ghana Mega trip proved yet again to be a resounding success! We notched up a fantastic species total in 23 days, where we covered the length and breadth of the country and a great variety of habitats in this superb West African country! Our tour started off with a visit to Shai Hills. This small but fabulous reserve has a nice variety of habitats including mixed woodland, grassland, wetlands and granite outcrops and therefore supports an interesting array of bird species. During our morning exploring the reserve we recorded African Cuckoo-Hawk, Western Marsh Harrier, Red-necked Buzzard, stunning Violet Turaco, numerous immaculate Blue-bellied Roller, Vieillot’s and Double-toothed Barbets, Senegal and African Wattled Lapwings, White-shouldered Black Tit, Red- shouldered Cuckooshrike, Black-bellied Bustard, Senegal Parrot, Senegal Batis and restless Senegal Eremomela. A number of migrants were seen including Willow Warbler, Whinchat and Spotted Flycatcher. Even mammals showed well for us as we had a number of Kob, Bushbuck, Olive Baboon, Callithrix Monkey and unusually good views of Lesser Spot- Blue-bellied Roller by Markus Lilje nosed Monkey! Well pleased with our morning’s birding, we left Shai Hills and made our way to Ho. En route we stopped for lunch near the Volta Dam where we enjoyed most memorable close-up encounters with Mangrove Sunbird and Bronze- tailed Starling. -
