The slogan “Serengeti shall not die” (German: Serengeti darf nicht sterben) is widely credited for alerting the global community to the urgency of conserving the Serengeti and its biological values for the benefit of local and global communities. The slogan has become popular since 1960 when Bernhard and Michael Grzimek authored a book, Serengeti Shall Not Die. However, despite this commitment the management challenges in Serengeti are growing, causing skepticism about the potential for realizing such a goal. These challenges include illegal hunting, habitat loss, and human-wildlife conflicts aggravated by human population growth and poverty. In addressing these challenges and therefore transforming the ambition “Serengeti shall not die” into reality, the multiple strategies required are presented in this paper. The paper starts by reviewing the challenges contradicting the ambition.

The concept of payments for environmental services (PES) lends itself to an extremely diverse array of experimentations. At a time when PES are likely to be scaled up massively in certain parts of the tropics, notably in the context of REDD+, it is important to refine the scope of implementation of the instrument to avoid several perverse effects specific to PES and sustain its benefits over time. We analyze recent developments in PES based on a review of literature and emerging practices as we observe them in the field. Using various elements from the theory of economics, public action and environmental management, we flag five key aspects of PES that are often overlooked in most influential studies on PES: (1) the nature of the environmental service providers, (2) the actual efficiency gains of involving industrial and commercial actors, (3) the type of contractual obligations incumbent to the providers and duration of payments, (4) the potential macroeconomic effects of an upscaling of PES, and (5) the risk that PES undermine the consolidation of fragile states. If these elements are not properly addressed in the design of PES, this paper explains that the instrument risks delivering only ephemeral environmental results, while inducing a dangerous shift towards the ‘polluter-profits’ principle. Conversely, we explain how systematically going beyond monetary payments and integrating elements of technical support to encourage alternative productive activities is key to sustain PES benefits over time.

An integrated framework for assessing conservation and development changes at the scale of a large forest landscape in the Congo Basin is described. The framework allows stakeholders to assess progress in achieving the often conflicting objectives of alleviating poverty and conserving global environmental values. The study shows that there was little change in either livelihood or conservation indicators over the period 2006 to 2008, and that the activities of conservation organizations had only modest impacts on either. The global economic down-turn in 2008 had immediate negative consequences for both local livelihoods and for biodiversity as people lost their employment in the cash economy and reverted to illegal harvesting of forest products. Weakness of institutions, and corruption were the major obstacles to achieving either conservation or development objectives. External economic changes had more impact on this forest landscape than either the negative or positive interventions of local actors.

Brown palm civet diet was assessed by examining 1,013 scats between May 1996 and December 1999 in Kalakad-Mundanthurai Tiger Reserve, Western Ghats, India. The brown palm civet is predominantly frugivorous, with fruits of 53 native species and four species of introduced plants comprising 97% of its diet. There was high intra- and inter-annual variation in the diet of brown palm civets. Civets adapted to fluctuations in fruit resources by feeding on a diverse range of species and supplementing their year-round, primarily frugivorous, diet with invertebrates and vertebrates. Civets mainly ate fruits of trees and lianas, rarely those of herbs or shrubs. Fruits eaten by civets were mostly small (<1 cm diameter), multi-seeded, pulpy berries, and drupes with moderate to high water content, along with several large (>2 cm) fruits like Palaquium ellipticum, Elaeocarpus serratus, Holigarna nigra, and Knema attenuata. The brown palm civet is a key mammalian seed disperser in the Western Ghats rainforest by being predominantly frugivorous and dispersing a diverse array of plant species. As brown palm civets can persist in fragmented rainforest, they can play a major role in restoration of degraded fragments in these landscapes. The results emphasize the need to recognize the importance of small carnivores as seed dispersers in tropical forests.

Home range and food habits of tigers (Panthera tigris tigris) were studied in Sariska Tiger Reserve from July 2008 to June 2009. Three tigers (one male and two females) were radio-collared and reintroduced in Sariska Tiger Reserve from Ranthambhore Tiger Reserve, Western India during 2008-2009. The reintroduced tigers were monitored periodically through ground tracking using “triangulation and homing in techniques.” The estimated annual home ranges were 168.6 km² and 181.4 km² for tiger and tigress-1 respectively. The estimated summer home range of tigress-2 was 223.4 km². In total, 115 kills and 103 scats of tigers were collected to study the food habits. The line transect method was used to estimate the prey availability. The density of peafowl (Pavo cristatus) was found to be highest (125.2 ± 15.3/ km²) in Sariska followed by livestock (Bubalis bubalis and Bos indicus) (59.9 ± 22.3/ km²), chital (Axis axis) (46.7 ± 9.5/ km²), sambar (Rusa unicolor) (26.2 ± 4.9/ km²), common langur (Semnopithecus entellus) (22.8 ± 6.5/ km²), nilgai (Boselaphus tragocamelus) (19.5 ± 3.3/ km²) and wild pig (Sus scrofa) (15.4 ± 4.4/ km²). Tigers fed on seven prey species as shown by kill data. Tigers' scat analysis revealed the presence of five prey species. Prey selection by tigers based on scat analysis was in the following order: sambar> chital> nilgai> livestock> common langur. It is proposed to restock the tiger population initially with five tigers in Sariska and subsequent supplementation of two tigers every three years for a period of six years, which will allow the population to achieve demographic viability. Removal of anthropogenic pressure from the national park will be crucial for the long term survival of tigers in Sariska.

The successful management of natural resources requires access to adequate information on social, economic, ecological, and cultural changes in order to mitigate their impacts through conservation interventions. In most cases, such information is provided in the form of simple diversity indices, which may not predict the complex nature of species functioning in ecosystems. In this study, we used rank abundance, analysis of similarities (ANOSIM), similarity percentages (SIMPER), and taxonomic-diversity and distinctness indices to show the status of tree and shrub species in Kasagala forest reserve in central Uganda. Four 100 × 100 m plots were established in four vegetation strata of the strict nature reserve of the forest, and diameter at breast height (DBH) of trees and shrubs ≥ 5 cm measured. There was no significant difference in species abundance in the four vegetation strata (Kruskal Wallis H = 2.614, p = 0.453; ANOSIM: R = −0.334, p = 0.995). The taxonomic diversity and distinctness of the four vegetation types ranged between 2.414 and 2.786 while the taxonomic distinctness values ranged between 2.897 and 2.978. The taxonomic diversity of the forest is generally even, suggesting a homogeneous community. We suggest that the managers of the forest constitute a continuous monitoring program aimed at controlling the impact of anthropogenic factors, one of the main influences for such low taxonomic distinctness values observed for this forest.

Degraded lands in the Colombian Andes have been restored by means of monospecific tree plantations of native and exotic species, and by abandoning lands to natural regeneration. Both methods rapidly produce a vegetation cover that helps to stabilize soils, but the value of resulting ecosystems for wildlife needs to be evaluated. We assessed the effects of these two restoration methods on the diversity and abundance of bess beetles (Passalidae), which are important deadwood recyclers. We quantified coarse woody debris (logs and branches >10 cm diameter) and associated passalid beetle fauna in 40-year-old Andean alder (Alnus acuminata) plantations, adjacent natural regeneration and old-forest remnants, at 2430 m of elevation in the Central Andes. The three forest types contained the same number of logs per unit area, but wood volume was lower in alder stands than in natural forest types. Old-forest remnants contained a higher number of occupied logs and individual beetles per transect and per unit wood volume than the two other habitats. We found six species of beetle, three of which were found in the three habitats and the other three in one habitat each. Forest remnants and natural regeneration had four species each, whereas alder plantations had three species. Although beetle abundance was lower in alder stands, in the small-scale mosaic found at this site alder plantations behaved similarly to secondary forest and merged as part of the local habitat heterogeneity. Whether these results apply to larger and more isolated plantations remains to be established.

This paper highlights the global and the regional scale representation of wetlands ecosystems using geospatial tools and multiple data sets. At global scale, the Ramsar database is investigated for representation of the wetlands sites of international importance against the “global agricultural zones” derived from the thematic aggregation of Global Irrigated Area Map databases. The analysis of “Ramsar sites” under cultivation reflects the present trend in wetlands use for agriculture. The scenario is also compared with the historical pattern derived from Vavilov's food zones of 1926. Observed is an aggregate increase in cropped wetlands area from 25% (1926) to 43% (2006). The second component develops a regional partnership with Salim Ali Centre for Ornithology and Natural History in India. The partnership reviews the thematic national database of inland wetlands and “priority wetlands habitats” (PWH) in comparison with the bio-geographic and agro-ecological factors (regions/sub-regions) and by means of geographical information system (GIS) tools. We elaborate the strength of spatial tools to better understand the relationship between wetlands distribution and agricultural zones, both historically and at the present time. The disseminated message states, though from a technical perspective, the understanding of scale and resolution in combining information from diverse sources is essential; the effective implementation of spatial analysis requires a true cross-disciplinary approach. Complementing that, relevant policy support and appropriate institutional arrangements are fundamental to advance the management work required for unification of wetlands conservation with the existing challenges of food and livelihood security.
