Natures Matrix: Linking Agriculture, Conservation and Food Sovereignty

Landscapes Are Frequently Seen As Fragments Of Natural Habitat Surrounded By A Sea Of Agriculture But Recent Ecological Theory Shows That The Nature Of These Fragments Is Not Nearly As Important For Conservation As Is The Nature Of The Matrix Of Agriculture That Surrounds Them Local Extinctions From Conservation Fragments Are Inevitable And Must Be Balanced By Migrations If Massive Extinction Is To Be Avoided High Migration Rates Only Occur In What The Authors Refer To As High Quality Matrices, Which Are Created By Alternative Agroecological Techniques, As Opposed To The Industrial Monocultural Model Of Agriculture The Authors Argue That The Only Way To Promote Such High Quality Matrices Is To Work With Rural Social Movements Their Ideas Are At Odds With The Major Trends Of Some Of The Large Conservation Organizations That Emphasize Targeted Land Purchases Of Protected Areas They Argue That Recent Advances In Ecological Research Make Such A General Approach Anachronistic And Call, Rather, For Solidarity With The Small Farmers Around The World Who Are Currently Struggling To Attain Food Sovereignty.Nature S Matrix Proposes A Radically New Approach To The Conservation Of Biodiversity Based On Recent Advances In The Science Of Ecology Plus Political Realities, Particularly In The World S Tropical Regions.Natures Matrix: Linking Agriculture, Conservation and Food Sovereignty

    Nature s Matrix is a manifesto for a new paradigm in conservation biology It gives sustainable agriculture a productive role in region scale ecological restoration and puts small indigenous communities in the driver s seat The book is really amazing and says so many awesome things that I am struggling to keep it all coherent here.Vandermeer and Perfecto start with a new model for species conservation, the metapopulation Many species historically existed in metapopulations Island and pond creatures are at an extreme end, forced to traverse many leagues of totally inhospitable terrain to reach other population groups and mix genes Disturbance adapted forest plants and floodplain annuals are similar, since they must quickly hop to wherever the canopy is clear, traversing heavy shade in the process Today, almost every conservative species exists in a metapopulation state, forced to cross some hostile matrix to reach other population centers The crucial lesson here is that species persistence in the long term depends on migrations between these areas, since random ...

    The argument of this book is essentially a Most native habitat in the tropics is highly fragmented and exists within a matrix of alternate land usesb Local extinctions within this matrix are inevitable, however, can be counterbalanced by migration, i.e global extinctions are not inevitablec The extent to which migration occurs is strongly dependent on the quality of the matrixd High quality matrixes support migration of various taxa through landscapes and prevent local extinctions from summing to global extinctions low quality matrixes are hostile to migration e The primary focus of biodiversity conservation should be on the quality of the matrixMost land uses in the tropics are different forms of agriculture, so Perfecto et al focus their argument on how ecological planning and sustainable practices within agricultural landscapes can be made conducive to species migration They argue that agriculture has historically been conceived of as a zero sum game i.e as necessarily being exclusionary of biodiversity conservation but that instead, agricultural systems can be and are an important repository for biodiversity Small scale, low input intensity and poly cropped agro ecosystems are the best such repositories, and for this reason, ...

    The park system is the prevailing model for biodiversity protection in the world think Teddy R and the US National Park Service think Tanzania s Selous National Park, the biggest in the world Armed guards, strict rules, nature here, humans there Biologists have long recognized that local extinctions are common, even in these big, dynamic parks, so corridors were the rage a few years ago, little pathways that would connect two natural areas to each other to allow migration the solution to local extinction bridges over busy highways, for example Most ecologists have found this approach hasn t worked Using a dazzling array of different disciplinary perspectives biology, history, politics, anthropology , Perfecto et al propose a matrix model of biodiversity protection that recognizes humans as potential stewards of the environment right where they live and work Conservationists, they argue, have been blind to the political realities that drive extinction in the most sensitive regions, regions that happen to be in the poorest areas of the world They focus their attention on agriculture, which has been such a destructive force in places like Brazilian But they draw an importa...

    The authors extend the simple idea behind shade grown coffee that the success of the neotropical migrants that visit the temperate U.S every spring depends in part on the quality of their wintering grounds in Central America into a elaborate model that encompasses a much wider group of factors, including resident species, other agroforestry systems, and farmers rights to the land they depend on In their view, agriculture is seen as ecosystem management, and political solutions to poverty are preferred to technological ones.

    Perfecto et al point out that a given species is always at risk of being locally extirpated from a given area of land, with a probability of e But the likelihood of global extinction, given by the formula 1 e m, where m is the probability that a population will migrate into a given area Managing the migration rate is just as important as managing the extirpation rate Patches of land cropped into coffee, cacao, or corn and beans, if properly managed, can provide local migration connections between stands of deep forest, serving the same needs as conventional wildlife corridors The authors cite as an example the Highland Guan Penelopina nigra , which doesn t visit a coffee farm to feed, but rather as a route between wooded areas.

    The authors reject the mainstream approach to habitat protection, designating areas in which agriculture is forbidden, and backing up that protec...

    From the title and the physical aspect of this book, I figured it would read like a textbook and that I would struggle to finish it However, I received this book from someone I greatly admire and whom I wouldn t want to disappoint by NOT fi...

    This book mixes the science of conservation biology and the politics behind it in very accessible language It It gives a good analysis of the situation as it plays out in Latin America I learned a lot.
