Dr. Md. Shairul Mashreque and Dr. M Abul Kashem Mozumder :
Conservation of biodiversity of course ensures sustainable development. Development is sure to be turned into a meaningless effort if it affects biodiversity. Making plant of electricity and other energy in forest areas especially mangrove forest will be baneful as it may slowly destroy forest resources. It goes against resource creation and conservation. Apprehension is that our tiger population is on the decline. Development inside or near the forest become detrimental disturbing natural growth of flora and fauna.
All animals and their species including tiger are our resources. We have to conserve it. To cite a report:
Sundarbans Forest (10,000 km2) represents the only mangrove ecosystem inhabited by tigers Panthera tigris. However, in the Bangladesh portion of the Sundarbans (6,000km2) tigers appear to have declined. The aim of this study was to examine the influence of a range of environmental and landscape variables in possible changes in the relative abundance of tigers in the Bangladesh Sundarbans over a five-year period (2007-2011). In 2007, 2011 tiger relative abundance was assessed using sign surveys. Using regression models we investigated changes in relative abundance versus multiple landscape variables (human disturbance associated with villages and commercial shipping lanes, distance to the international border with India where there is enhanced patrolling, presence of forest guard stations, number of criminal prosecutions and forest protection status). Tiger relative abundance was higher in 2007 and declined by 2011 with changes best explained by the proximity to international boundaries. This result might have been affected by the high levels of security patrols at the India-Bangladesh border along with cross border tiger movement between India and Bangladesh. Neighboring tiger range countries could strengthen cross-border law enforcement, increasing protection of dispersing animals. Particularly alarming was the absence of a positive effect of protected areas relative to those outside the protected area system or forest guard stations, implying a lack of management effectiveness suggesting an urgent need for an improved strategy for managing tigers and their habitat
Across their range, tigers (Panthera tigris) are severely threatened by poaching for global markets, prey depletion, and from the loss and fragmentation of habitat due to infrastructure development. Threats to tigers are sometimes heightened along porous country borders due to cross-border poaching and illegal trade. However, the overall declining population trend for tigers is not matched by the overall rate of loss of habitat across the geographic range suggesting that with effective protection, populations could recover as there is ample potential tiger habitat and prey in at least part of their range to support them.
Recognizing the serious predicament for large cats in general, in recent years significant resources have been made available from the donor community for tiger conservation. Protecting tiger populations and habitats has become a priority for national governments and partner agencies. As a result of improved management practices tigers are starting to recover in some parts of their range e.g.
Thailand. In order to better understand the correlates of tiger status, managers need to understand how tigers respond to management practices and human disturbance. For example, target animal abundance may decrease away from ranger stations in response to declining levels of protection.
Furthermore, large cat presence as measured by concentration of detections may be reduced in areas populated with tourists in response to elevated levels of human traffic compared with areas with less human traffic. In addition, mortality of tigers may increase where infrastructure development penetrates wild areas posing a risk from collisions from vehicular traffic.

What does biodiversity mean for human health?”
In fact biodiversity protect our ecosystem and the system of livelihood. “People depend on biodiversity in their daily lives, in ways that are not always apparent or appreciated. Human health ultimately depends upon ecosystem products and services (such as availability of fresh water, food and fuel sources) which are requisite for good human health and productive livelihoods.
Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause political conflict.”
“There is growing concern about the health consequences of biodiversity loss and change.
Biodiversity changes affect ecosystem functioning and significant disruptions of ecosystems can result in life sustaining ecosystem goods and services. Biodiversity loss also means that we are losing, before discovery, many of nature’s chemicals and genes, of the kind that have already provided humankind with enormous health benefits. Specific pressures and linkages between health and biodiversity include”.
We appreciate on going development and modernization process. Infrastructural development is being lavishly financed with ADP and PPP taking policy lead. But the pains of development are being felt by the beneficiaries. Nevertheless most development projects have become counterproductive affecting sustainability. Bio diversity loss has become maximised. The thin tanks in development and policy dialogues should think of project governance circumspective so that it does not trespass upon natural rights.
