PAST, PRESENT AND FUTURE FRIENDS FOR CONSERVATION: POSSIBLE OPTIONS IN THE 21 CENTURY
Population growth and under development in cash-strapped African countries have created
enormous pressures on the land which in most cases leads to the decline of biodiversity
and long term degredation of habitat. The clock cannot be turned back but conservation
programmes can be pro-active with some chance of success. Leaving 'nature' to take
its course may work but a hands on interventionist management approach may be more
effective. The best chance of success will depend upon the size of the area to be
managed and the ability to influence land use policy beyond the conservation areas.
Science as a basic component of decision making is taken as a given but persuading
managers to use scientific arguments is not generally practiced in poorly resourced
conservation authorities. The promotion of scientific method as a part of management
is a critical challenge for conservation programmes in Africa but to be successful,
funding sources must be found to carry the costs of "good" plans.

PEOPLE AND WILDLIFE IN AFRICAN LANDSCAPES: IS THE FUTURE OF THEIR CO-EXISTENCE A
REALITY OR WISHFUL THINKING?
The state of Africa’s mega-fauna is unclear, particularly in human-dominated landscapes
outside protected areas. Here, I attempt to ask two questions: When do people successfully
co-exist with mega-fauna and when do they not? What does this suggest about the future
of large wildlife over the next few decades? To do this, I review the literature
from across the continent and give examples from recent data collected in East African
savannas. I then present potential futures of selected species of large mammals,
using human — wildlife population relationships and human population growth models.
The literature, on balance, shows more examples of wildlife decline than maintenance
in the face of increasing human domination of landscapes, with a few notable exceptions.
Much wildlife also has been lost where there is little human domination because of
insecurity and revolution; in other instances the state of wildlife is simply unknown.
In a few places, peopled landscapes appear to support more wildlife than adjacent
protected areas because moderate human use facilitates wildlife use. Future scenarios
suggest that people will continue to intensify land use where wildlife is abundant,
especially in East Africa, where human pressure on wildlife-rich landscapes is some
of the highest on the continent.

CLIMATE CHANGE AS AN IMPORTANT THREAT TO BIODIVERSITY CONSERVATION IN AFRICA: FACT
OR FICTION?
Against the backdrop of socio-economic and political challenges faced by African
states the threat posed by global climate change may appear remote or even insignificant.
The reality is however, that the degree and rate of climate change expected across
the continent is likely to seriously compromise the continents biodiversity estate
as well as ecosystem service delivery to large numbers of people. An overview of
predicted climate changes, its consequence for critical vegetation types, coral reefs,
species, protected areas, ecosystem services, health systems and agricultural systems
illustrates significant losses of vital resources, considerable geographical displacement
or increased land-use conflict in the near future. Collectively these effects may
not only undermine the biodiversity estate of the continent, but also exacerbate
current socio-economic and political realties, escalating the potential for human
tragedy and regional tension.

POLLINATOR CONSERVATION FOR HUMAN SURVIVAL
Pollination is essential for ecosystem service. Although many plants are wind pollinated,
most are animal-pollinated, making the conservation of pollinators fundamental to
the maintenance of biological diversity, and diversity in human diet. Pollination
normally precedes regeneration, and initiates processes that result in dormancy and
dispersal. Sexual reproduction in plants also provides food for other organisms,
including man. The variety of plant foods available is a combination of food types
and plant diversity, and includes pollen, nectar (that is converted into honey),
fruit, seeds, roots and foliage. In both natural areas and agricultural lands pollinators
must be sufficiently abundant to sustain their service. The conservation of pollinators
must consequently revolve around the maintenance of the pollination process. Criteria
for the conservation of a process differ from those applied to the conservation of
threatened species; sufficient abundance to maintain the population must be translated
into adequate numbers to sustain organisms that feed on a pollinator’s host plant.
Pollination has been a concern for millennia, and its importance is recognized in
the Convention on Biological Diversity (CBD). The CBD mechanism dealing with this
issue is the International Pollinator Initiative (IPI), and Africa has played an
important role in the development of the IPI.

FORESTS: ARE THEY THE LAST FRONTIER FOR CONSERVATION IN AFRICA?
Tremendous loss of biodiversity in Africa followed the shrinking of its forests since
the Quaternary when forests covered almost 95% of the continent, including the Sahara
and Kalahari deserts. However, the last century, especially the last 40 years, witnessed
an accelerated and irreversible loss of Africa’s forests and biodiversity. We present
continental- and country-scale evidence of a linear relationship between forest shrinkage
and loss of biodiversity in Africa. Our data indicate that biodiversity hotspots
are correlated with fragmented forests in East and West Africa, the Congo-Guinean
biome, the mountain and highland forest ecosystems (Nimba, Fouta Djallo, Cameroon,
Albertine Rift), and the Cape, Madagascar, and gallery forests. Forest shrinkage
and biodiversity loss are currently taken seriously, especially given people’s dependence
on forest biological resources. Many countries are prioritising their land use and
conservation planning strategies by reserving critical sites as protected areas through
policy and modest means of management. There is an increasing devolution of biological
resource management from government to local communities, but it remains uncertain
whether measures taken so far can reverse the trend. However, we are optmistic that
Africa’s forests will stand against desertification and could represent the future’s
last frontier for biodiversity conservation and its sustainable utilisation.

PROMOTING LARGE-SCALE CONSERVATION IN AFRICA: ISSUES AND SOME WAYS FORWARD.
Conservation organizations are developing and rolling out broad-scale conservation
approaches in different ways and in diverse contexts. This paper compares AWF’s Heartland
Conservation Process to the large-scale approaches of organizations with programs
in African landscapes in which AWF is operating and chronicles AWF’s experiences
and lessons emerging from applying the process in some these within country and cross-border
sites. Large-scale conservation makes if there are shared resources, threats, efforts,
and potential to benefit from shared resources. Consultation processes have varied
predicated upon initiatives and plans across landscapes. Large-scale conservation
has largely entailed cross-border collaboration, but many sites are not formal TBNRM
areas. Differences among approaches include where conservation should be done, how
it should be done, the scale of at which it should be done and the tools / methods
that should be used. But approaches are similar in some respects such as in the identification
of conservation targets and collaborations can be made more fruitful. Advancing broad-scale
conservation for sustainable impact will require explicitly articulated strategic
plans, supporting policy, clarity of responsibilities and roles, commitment and empowerment,
among others discussed in this paper.

CONFLICT AND DISEASE: CONSERVATION’S GREATEST ENEMY IN AFRICA
Reports of conflict and disease in Africa dominate international headlines. There
is no doubt that these twin disasters of instability have taken a devastating toll
on people of this vast continent. However, what does this mean for conservation?
How have guns and germs, and the general instability that they sow, influenced the
current status of conservation in Africa? In this paper, we consider the past, present
and future impact of instability on conservation in Africa. The interaction between
instability and conservation is indeed complex, and the intensification of conflict
and instability has brought new urgency to our understanding of its impact on conservation.
With as much as a conservative 20% of the continent impacted by conflict and disease,
an assessment of the current situation is critically needed. Through case studies
from West, East, and southern Africa, we explore the effects of instability on Africa’s
threatened species and habitats. In the interest of future management and intervention,
we propose an "Instability Index" for monitoring the effects of disease
and insecurity on conservation in Africa. Only through an understanding of the nature
and extent of the problem can we propose useful guidelines to conservationists for
addressing the complexities of instability in Africa.

CONSERVING ELEPHANTS IN FOREST FRAGMENTS: BIODIVERSITY AND LOCAL COMMUNITY CONCERNS
Maintaining elephants in forest fragments presents serious challenges given their
impact on local biodiversity and neighboring communities. We describe socioeconomic
impacts of crop raiding by elephants at Kibale Forest, Uganda where elephants account
for >50% of all damage to wildlife. However, their damage is patchy and affects
only a few farms who suffer severe losses. Guarding and other individual defensive
strategies have proven ineffective. Among crop raiding species, only elephants cause
individuals to abandon farms, and smallholders are particularly vulnerable. At Shimba
Hills Reserve, Kenya, electric fence barriers protect neighboring farmers from crop
raiding. This placates local communities, but the confined and growing population
of elephants has had devastating effects on the forest. Compounding the problem is
the patchy distribution of elephants with a concentration of bulls in a small area.
Bulls topple trees resulting in rapid changes in forest canopy structure which alters
microclimate and light conditions, and changes the environment for the re-establishment
of canopy trees. Foraging preference and avoidances also alter floristic composition
of the forests. Forest recovery after elimination of elephants may be delayed due
to high levels of current damage. We identify several management options and discuss
their financial, ecological, ethical and political costs.

FUNDING CHALLENGES: IS THE DONOR THE PROSECUTOR, JUDGE AND EXECUTIONER OR IS THERE
A PROBLEM WITH THE AFRICAN RECIPIENT?
This paper describes the experience of an African applicant seeking a grant from
an international funding agency. Potential factors that may influence the success
or failure of an African’s grant application, and the significance of a review process
that allows a re-submission following referees’ initial comments, are discussed.
By contrast, funding challenges from a donor’s perspective subsequently experienced
by the same applicant but while engaged by the United Nations Children Fund (UNICEF)
in the Democratic Republic of Congo, as well as the United Nations Development Programme
(UNDP) and the Global Environment Facility (GEF) for African and non-African proponents
across the African continent are also described. For the past 5 years, 130 grant
proposals were received and reviewed for eligibility, with the applicant directly
involved in 35 GEF grant proposals. Although applicants or major drivers of these
proposals were classified as either African or non-African, there was no significant
difference between the two groups. Overall, however, African applicants tended to
be less successful grant-seekers. It was concluded that African applicants may have
the potential to succeed in their grant applications so long they apply "grant-man-ship"
principles, especially by aligning their objectives with donor institutional mandates,
following guidelines, and meeting deadlines.

COMMUNITY-BASED CONSERVATION AND TRANSBOUNDARY PARKS: ARE THEY EFFECTIVELY CONSERVING
AFRICAN BIODIVERSITY?
The prevailing conservation paradigm for Africa rests heavily on promoting community-based
wildlife conservation (CBWC) and establishing transfrontier conservation areas (TFCAs).
Key assumptions underlying CBWC are: (1) if villagers have full proprietary rights
over their wildlife resources their vested interests will restrict hunting to sustainable
levels; (2) that indigenous ecological knowledge provides the basis for villagers
to manage their wildlife resources sustainably. These assumptions presuppose that
villagers have the ecological tools to estimate sustainable offtake levels and that
traditional ethics of resource-use favour sustainability despite current human population
densities and the use of rifles for hunting. An assumption of TFCA planning is (3)
that in addition to political, cultural and economic benefits, TFCAs contribute significantly
to biodiversity conservation without sacrificing landuse efficiency. Using examples
from southern Africa we question these three assumptions and argue that windows of
opportunity for biodiversity conservation are closing fast across the African continent.
Appropriate ecological tools have to be provided and employed to ensure that CBWC
is based on sustainable hunting and that TFCA planning incorporates issues of reserve
design to achieve effective representation of the biodiversity hierarchy. We outline
approaches to address these challenges for Africa at community and regional scales.
