The importance of Bees for Coffee pollination

Let's take a jump over the gulf of mannar then towards Mysore. Multilayer agroforestry systems cannot only be found in the hilly side of Sri lanka but also here in India. Actually, the importance of healthy, multilayered, native systems for pollination success has recently been shown in a ETH study by Boreux and Krishnan. They not only shed light on a misconception that for good coffee harvest light is a limiting factor but they illustrate that native trees as Teak and Rosewood, despite growing slower than introduced Silver Oak (Grevillea robusta), are a better support for coffee pollinating crucial bee species. It is important to note these observations and keep such interrelationships in mind when working on similar systems, e.g. in the Kandy province in Sri Lanka.

Ecotourism - Agroforestry - Kandyan Homegardens

How can ecotourism be described? Eco travel is it only a marketing slogan? Often eco tourism is understood as touristic activites close to nature or natural habitats. But is not exactly this kind of tourism particularily destructive?
Take Sri Lanka for example, should we go to Sinharaja? Should we merely protect certain habitats and leave other to be distroyed? I think "NO", however, looking at demography and travel worldwide the only way to protect biodiversity may be anthropogenic but nature like habitats. Kandyan homegardens are something close to this (in certain aspects at least), although densely populated the area is full of small agroforestry like structures (see image, which from a crop like perspective represents more african species than east asian...).

These systems are often also characterized by living fences and the like. Due to the different canopies many trophic levels of insects, animals and plants can dwell. Clearly an increase in biodiversity. But what has this do to with tourism? Consult the main points for little impact travelling. There are other interpretations of ecotourism which do not focus on "close to nature" but compensate your impact while travelling....
