Wel­come to the Bio­di­ver­sity Off­sets Blog! This site aims to pro­vide an inter­dis­ci­pli­nary plat­form for the infor­ma­tion and exchange on Bio­di­ver­sity Off­sets, the Mit­i­ga­tion Hier­ar­chy and the wider context.

The About-section in the menu above gives you a brief intro­duc­tion to what bio­di­ver­sity off­sets are and sum­ma­rizes the objec­tives of this blog. You may also want to get to know about me and my PhD (which is the basis for this blog).

The Bio­di­ver­sity Off­sets Blog has only recently started (it went online in August 2014) and thus will con­tin­u­ously be updated with any upcom­ing infor­ma­tion. The whole bunch of infor­ma­tion that has risen in the past few years will also be incor­po­rated bit by bit.

As the focus of this plat­form is to bring peo­ple and their exper­tise together, please get in con­tact if you have any­thing to share. It is highly wel­comed if you would like to write posts or reviews or share pho­tographs (Please request author rights). You can also com­ment to any post or start a dis­cus­sion on the open dis­cus­sion plat­form.


In this sense you are also kindly requested to answer the cur­rent polls (see in the side­bar on the right or below if you are using mobile devices). Thank you.

Please find below a list of all posts or choose from the menu above for a spe­cific focus.


Have a look at the Experts and Exchange sec­tion if you want to get to know experts in the field of bio­di­ver­sity off­sets from all over the world with their respec­tive focus of exper­tise or explore past and present PhD top­ics.


Have a look at the sources sec­tion to explore rel­e­vant lit­er­a­ture as well as a grow­ing list of links to web­sites.


It is greatly appre­ci­ated if you’d con­tribute to and exchange on bio­di­ver­sity off­sets on the ground. See infor­ma­tion on poli­cies and gov­er­nance and also world­wide exam­ples of bio­di­ver­sity offsets.

Marianne Darbi awarded EIA Study Award for her PhD on Biodiversity Offsets

EIA Study awardI had blogged about it ear­lier how happy I am to receive the EIA Study Award of the Ger­man Soci­ety for Envi­ron­men­tal Impact Assessment.

The big day had finally come Thurs­day, 30 Novem­ber and I was enjoy­ing both an inter­est­ing EIA con­gress with lots of inspir­ing talks from prac­ti­tion­ers, pol­i­cy­mak­ers, sci­en­tists and admin­is­tra­tion. But of course, my per­sonal high­light was the offi­cial award cer­e­mony. Thanks to the jury for choos­ing my work for this prize and espe­cially thanks to Prof. Sabine Baum­gart for a fan­tas­tic lau­da­tion (some­times I couldn’t believe she was speak­ing about me and my work ;o)). And again, heart­ful thanks to all of you for your sup­port and con­tri­bu­tion to this work and the warm words and con­grat­u­la­tions that I have received so far.

After upload­ing the Ger­man offi­cial press release, I now want to share the Eng­lish ver­sion of the press release with you. For whom this may be a bit too for­mal, find below also some pho­tographs :o)

Offi­cial press release on the EIA study award

Mar­i­anne Darbi, research assis­tant at the Leib­niz Insti­tute of Eco­log­i­cal Urban and Regional Devel­op­ment (IOER), has received the EIA Study Award 2016 for her dis­ser­ta­tion on the mit­i­ga­tion of envi­ron­men­tal impacts. With a prize of up to € 5,000, the award goes to out­stand­ing research in the field of envi­ron­men­tal impact assess­ment (EIA). It was awarded by the Ger­man Soci­ety for Envi­ron­men­tal Impact Assess­ment (UVP-Gesellschaft) end of Sep­tem­ber. Mar­i­anne Darbi had con­vinced the inde­pen­dent jury with a global typol­ogy of mea­sures to com­pen­sate for bio­di­ver­sity loss. Con­tinue read­ing

No Net Loss and Biodiversity Offsets: documentation from the EcoSummit

IMG_7724As I had promised ear­lier, I am shar­ing with you some impres­sions and pre­sen­ta­tions from our bio­di­ver­sity off­sets ses­sion at the recent Eco­Sum­mit in Mont­pel­lier. After the gen­eral ses­sion descrip­tion and line-up of speak­ers, find below the abstract and pre­sen­ta­tion for each of the speak­ers (includ­ing a few pho­tographs). Con­tinue read­ing

I’m on twitter!


I am on twitterMany of you have asked me about my twit­ter name in the past two years — and I always had to reply that there was –err– none. but I had this on my to-do list for a long time. Hav­ing fin­ished my PhD I thought this was a great occa­sion to start over new and join twit­ter for an even more vibrant exchange on bio­di­ver­sity off­sets and fight­ing to halt bio­di­ver­sity loss.

You can fol­low me @MarianneDarbi (who would have guessed ;o)) and see all the updates from the Bio­di­ver­sity Off­sets Blog on LinkedIn and on Twit­ter.

BBOP webinar today, Wednesday, October 12, 2016: France’s new biodiversity law and implications for no net loss of biodiveristy

bbop-logoThis is a last minute reminder to reg­is­ter for another inter­est­ing BBOP webi­nar, tak­ing place today, Octo­ber 12.

Ophélie Darses, Deputy Bureau Chief of Global Pub­lic Goods from the French Min­istry of Envi­ron­ment, Energy and Sea, and Fabien Quétier from the French envi­ron­men­tal con­sul­tancy Biotope will present and dis­cuss the new pro­vi­sions intro­duced by the new French bio­di­ver­sity law includ­ing its impli­ca­tions on the rights and duties of “off­set oper­a­tors”, finan­cial guar­an­tees for off­sets, and a national pub­lic geo­ref­er­enced data­base on offsets.

As usual the webi­nar is part of the BBOP com­mu­nity of prac­tice (all pre­vi­ous webi­nars are archived there if you want to lis­ten to them later).

My PhD on biodiversity offsets has won the bi-annual award of the German EIA Association


I am just so super­happy that I need to share the good news with you: I have won the bi-annual EIA study award of the Ger­man EIA asso­ci­a­tion for my PhD on bio­di­ver­sity off­sets!!!  Look­ing for­ward to the offi­cial cer­e­mony at the EIA con­gress 28.-30. Sep­tem­ber in Bre­men, Ger­many! (I’ll soon also pub­lish some more infor­ma­tion on my PhD the­sis which basi­cally includes the devel­op­ment of a typol­ogy of bio­di­ver­sity offsets).

Webinar on Thursday, September 22, 2016: Principles for Achieving Net Gain Biodiversity Outcomes from Development

In this webi­nar, brought to you by IEMA, CIRIA and CIEEM, Julia Baker will out­line and review the best prac­tice prin­ci­ples for UK indus­try to achieve bio­di­ver­sity net gain out­comes from devel­op­ment. It will focus on recent prin­ci­ples, drafted and devel­oped through a col­lab­o­ra­tive and cross-profession based part­ner­ship. It will also pro­vide exam­ples of bio­di­ver­sity net-gain approaches and insights into devel­op­ing guid­ance.

SHORT INFO: When biodiversity offsetting can benefit nature

What’s it about in short: Giv­ing exam­ples from the UK con­text (Net­work Rail), Julia Baker argues that there are sit­u­a­tions when the frame­work for bio­di­ver­sity off­set­ting can ben­e­fit nature — and help us achieve our 2020 tar­get of halt­ing bio­di­ver­sity loss.
