Book Description
This is an eloquent, engaged and extremely well informed narrative of the environmental and natural resource conservation and management issues in Mozambique. While the topics in this volume are diverse, they are all explicitly designed to move beyond the routinized blame of natural resource mismanagement and environmental degradation on local communities, and to rethink ecosystem destruction, land degradation and natural resource over-exploitation in Africa and beyond. Never losing sight of the major causes of environment and resource mismanagement in Mozambique, the book advances the thesis that environment and resource problems are a result of compound factors such as poor governance, poverty, corruption, low education levels, and disregard of endogenous conservation epistemologies. A combination of all these factors makes the whole terrain of conservation even more complicated than ever; hence the need for urgent action by all social actors. This is a valuable book for environmental conservationists, land resource managers, social ecologists, environmental anthropologists, environmental field workers and technicians, practitioners and students of conservation sciences.

Book Description
Elephant management traditionally centers on reducing ecological impact and human-elephant conflict by controlling numbers. However, such an approach only deals with symptoms, and ignores the causes of the problem. Planning for cases when a species is a nuisance in some areas, but threatened in others, could benefit from the application of metapopulation theory. The theory offers a framework that is elegant, and have ecological as well as political appeal. Applying classic metapopulation theory to long-lived species that are widely distributed in stochastic environments where they can resist extinctions is problematic. However, empirical evidence for metapopulation structure may exist when applying more lenient criteria. I examined the literature for empirical support of classic criteria set by Hanski (1999) and for a more lenient sub-set of criteria proposed by Elmhagen & Angerbj??rn (2001) for specifically mammals. I propose that for small mammals (5kg) the full complement of classic criteria must be applied to yield perspectives on population regulation and conservation. However, for large (>100kg) and medium sized (>5 100kg) mammals only habitat discreteness, potential of demographic asynchrony and the likelihood of dispersal among sub-populations must be evaluated. Metapopulation theory could then be useful when constructing conservation plans that ensure the persistence of a species and contribute to forces that stabilize populations regionally. I evaluated the applicability of metapopulation theory to southern Africa's elephant sub-populations. I identified 51 discrete administrative sub-populations that occurred in six conservation clusters. Population growth rates varied across space and time within and among conservation clusters. Some sub-populations and conservation clusters increased or decreased while others remained stable. Therefore, elephant populations in southern Africa were in demographic asynchrony, both on a local and regional scale. I also suggest that dispersal may occur among sub-populations within clusters. Consequently, the regional population is stabilized by emigration to, or immigration from neighboring sub-populations as a result of demographic asynchrony across an ecological gradient. Elephant populations across southern Africa thus adhered to one and could possibly adhere to all metapopulation criteria. Observed changes in elephant numbers could also be the result of survey error. To gain an understanding of how survey error could affect estimates, I used dung counts and measurements to estimate population size and construct an age structure for the elephants living in the Maputo Elephant Reserve in Mozambique. I suggest that dung surveys can yield population estimates with known precision and can be used in monitoring programmes aimed at assessing population trends - despite the fact that it can be affected by observer bias. In this thesis I show that metapopulation theory provides the opportunity of applying a spatio-temporal approach to elephant conservation that is not obsessed with numbers. When implementing metapopulation theory, management no longer have to centre on elephants, but can focus on the landscape as a spatially and temporally dynamic area. Local fluctuations in elephant numbers could be construed within a regional context, rather than implementing management strategies on a local scale. Such an approach will focus on the causes rather than the symptoms of the elephant problem and may contribute to the persistence of elephants as well as other components of southern African biodiversity. AFRIKAANS : Die ekologiese impak van olifante en konflik tussen mense en olifante word tradisioneel hanteer deur olifant getalle te beheer. Ongelukkig los so? benadering net die simptome en nie die oorsaak van die problem op nie. Gevalle waar? spesie? problem is in sommige areas maar bedreig is in ander, kan baat vind by die toepasing van die metabevolkings teorie. Die teorie bied? elegante raamwerk wat op ekologiese en politieke gebiede aanklank vind. Die toepasing van die klassieke metabevolkings teorie op lang lewende spesies wat wyd versprei voorkom in stochastiese omgewings waar hulle weerstand kan bied teen uitsterwings skep egter probleme. Emperiese bewyse vir? metabevolkings struktuur kan egter voorkom waneer meer gematigde kriteria ondersoek word. Ek het die literatuur ondersoek vir emperiese ondersteuning vir die klassieke kriteria wat Hanski (1999) voorgestel het, asook vir? meer gematigte sub-groep van kriteria wat deur Elmhagen & Angerbj??rn (2001) vir spesifiek soogdiere voorgestel is. Ek stel voor dat die klassieke kriteria aangewend kan word om bevolkings van klein soogdiere (5 kg) te reguleer, beter te kan verstaan en dan te bewaar. Vir groot (>100kg) en medium groot (>5 100kg) soogdiere kan die metabevolkings teorie net gebruik word as die bestaan van aparte habitate, demografiese asinkronie en die potensiaal van verstrooing tussen tussen subbevolkings bewys kan word. Die metabevolkings toerie kan dan gebruik word om bewarings inisiatiewe in te stel wat spesies in staat sal stel om voort te bestaan en oor die streek te stabiliseer. Ek het die toepasbaarheid van die metabevolkings teorie vir suidelike Afrika se olifant sub-bevolkings ondersoek. Ek het 51 aparte administratiewe sub-bevolkings geidentifiseer wat in ses bewaringsklosse voorkom. Bevolkings groeitempos het binne in en tussen bewaringsklosse gewissel. Sommige het of toegeneem of afgeneem terwyl ander stabiel gebly het. Olifant sub-bevolkings in Suider Afrika was dus in demografiese asinkronie, op? lokale sowel as op? streeks vlak. Ek het ook voorgestel dat verstrooing kan voorkom tussen sub-bevolkings binne in bewarings klosse. Die olifant bevolking van die streek word dus deur emigrasie na, of immigrasie van naburige sub-bevolkings as gevolg van demografiese asinkronie oor? ekologiese gradient gestabiliseer. Olifant bevolkings in Suider Afrika het dus voldoen aan een, en kan potensieel voldoen aan alle metabevolkings kriteria. Opmerklike veranderinge in olifant getalle kan ook wees as gevolg van foute wat tydens tellings gemaak word. Om beter te verstaan hoe sulke foute bevolking skattings affekteer, het ek olifant mis tellings en metings gebruik om? bevolking skatting en ouderdomsstruktuur vir olifante in die Maputo Olifant Reservaat in Mosambiek saam te stel. Ek stel voor dat mis opnames bevolking skattings kan lewer wat bekende presiesie het en dat dit gebruik kan word in moniterings programme wat neigings in olifiant bevolkings ondersoek - alhoewel sulke skattings beinvloed kan word deur die vooroordeel van waarnemers. In hierdie tesis toon ek aan dat die metabevolkings teorie? geleentheid skep vir? ruimtelike-tydelike benadering in olifant bewaring wat nie net op getalle fokus nie. Wanneer die metabevolkings teorie toegepas word, kan bestuur op die landskap as? ruimtelike en tydsgebonde dinamiese area fokus, in plaas van net op olifant getalle. Lokale wisselings in olifant getalle kan binne in? streek konteks geinterpreteer word, eerder as om bestuurs inisiatiewe net op? lokale vlak in te stel. So? benadering sal fokus op die oorsprong in plaas van die simptome van die olifant problem en mag bydra tot die voorbestaan van nie net olifante nie, maar ook tot die biologiese diversiteit van Suider Afrika.

Book Description
Amazing photographs of elephants accompany narratives from researchers, scientists, and conservationists celebrating elephants and calling for their preservation African savanna elephants--among the most magnificent and beloved of our fellow mammals--are an extraordinary, social, and intelligent species. The Last Elephants, an homage to these animals and a clarion call for their preservation, is based upon a shocking finding: savanna elephant populations across Africa are being decimated, with two to three murdered every hour for their ivory. Without action, these elephants soon will vanish from our world. They are a species in imminent danger of extinction, and it is up to us to save them. Featuring more than 250 full-color photos of the breathtaking animals by some of the world's top wildlife photographers, The Last Elephants was inspired by the devastating results of the continent-wide Great Elephant Census of 2016, undertaken by Elephants without Borders in tandem with the world's most prominent conservation groups. The book joins together the voices and vision of scientists, lawmakers, rangers, conservationists, and on-the-ground researchers to speak out against elephant killings, to close loopholes in international law that allow the ivory trade to continue, and to pay tribute to the thousands who work to protect the animals, including African communities who have elected to preserve and protect their elephant neighbors. Offering both profiles of preservation plans that work and hope for elephants' future, this is a must-read for everyone concerned for the future of one of Earth's most captivating species.

Book Description
The author meets entrepreneur Jim on a 1988 North Pole adventure, discover they are both Africa enthusiasts. Returning from a waspish over the Andes pipeline experience in 1995, Jim recruits him for Africa to produce a feasibility study to obtain a 40,000 acre Indian Ocean look-alike San Francisco Peninsula development offered personally by Mozamique's President. The project goes through several near death experiences, end up an inimitable world class international tourist destination project. Jim has the largest wildlife refuge development by private enterprise on record, a 914 Sq Mi wildlife ecotourism development which safeguards the UN's botanically diverse region. But Jim fails to develop it, dies in 1999. The author now targets recruiting a billionaire or Disney to fund expanding to 4000 Sq Mi to connect to the nearby 38,500 Sq Mi worlds' largest wildlife refuge, to provide range to save 5000 Kruger elephants slated for mercy killing for overgrazing.

Book Description
The recovery of Gorongosa National Park's elephant population from decimation by war is an unparalleled conservation success story. Yet, a concomitant increase in crop-raiding by elephants along the boundaries of the Park now threatens to undo restoration efforts. Our project is the first to analyze the frequency, severity and distribution of raiding events around Gorongosa, and to experimentally evaluate strategies for reducing crop damage. We combined data on movements of crop-raiding elephants with data on crop availability, patterns of precipitation, NDVI, and the nutritional quality of natural versus cultivated forages to model the drivers of spatiotemporal variation in crop-raiding behavior by elephants. In addition, after one year of tracking the movements of crop-raiding elephants with GPS collars we identified 13 key crossing points used by elephants to exit the Park and access crops. We then experimentally tested three different strategies for deterring elephants from leaving the Park to raid crops at those locations: beehive fences, chili fences, and a combination of both ("spicy beehive fences"). In addition to using GPS collar data to quantify elephant responses to the fences, we trained two teams of local community members to collect quantitative data on crop damage by elephants and to help construct and maintain the experimental fences. We also installed 24 camera traps around the fences to document elephant behavior in proximity to each fence type. Elephants strategically altered their foraging behavior in natural versus cultivated landscapes, ostensibly to increase their intake of high-quality food in both environments. Specifically, elephants actively switched from "surfing the green wave" when foraging inside the Park to selecting mature crops that were browning down outside the Park as they moved between natural and cultivated landscapes. Our mitigation experiment revealed that elephants significantly avoided areas with beehive fences and chili fences, although all fence types increased the probability that elephants would return to the Park rather than continue on to raid crops after encountering a fence. The magnitude of this effect was greatest for the beehive fences, followed by the spicy beehive fences and fake beehives (beehive control). These results have important implications for reducing human-elephant conflict in Africa, and for helping to facilitate both the conservation of this iconic keystone species and the livelihoods of the many farmers who live in close proximity to them.
