Subsistence communities depend on forest resources and common lands to provide the necessities for survival. However, Western-based economic ideologies are greatly compromising the ability of these communities to perpetuate their traditional existence. Neoclassical economic principles promote the exploitation of important resources for use in markets. Also, as economic development and modernization ensues, land-use conversion inevitably results in further struggles to obtain the resources upon which many rely. This thesis explores biogas as an example of how fusion of ecological economic principles and ecofeminist values can be implemented to encourage sustainable development. An analysis of Nepal’s energy use by sector, supply and demand dynamics of fuelwood, land-use conversion within the district of Chitwan and the associated social, economic, and environmental issues caused by inefficient biomass consumption shed light on where sustainability and appropriate development efforts should be focused. My paper concludes that traditional Nepalese cooking methods need to be addressed in the face of misguided development and population growth, and the socioeconomic benefits associated with conversion to biogas technology is a good solution.

This paper aims to summarize the state of academic knowledge surrounding the economics of environmental innovation. Following a definition of environmental technology, the paper enumerates and describes the obstacles or constraints to the development of eco-innovation.
The groundmass in this thin section is a salt-n-pepper mixture of fine-grained, amorphous quartzofeldspathic phases. All phenocryts are subhedral in shape, and the largest of these, the k-feldspar and plagioclase are host to abundant hematite-filled fractures. Biotite and hornblende phenocrysts are much smaller. A few spherulites, seen more clearly in plane than cross polarized light, are found in the groundmass.
The groundmass of this porphyritic basalt is comprised chiefly of glass, plagioclase, and clinopyroxene, in decreasing proportions respectively. Some plagioclase phenocrysts have sieve textures, some inclusions of glass blebs, others are concentrically zoned, and still more are relatively fresh. Clinopyroxene phenocrysts frequently form glomeroporphyroclasts, sometimes with olivine; several grains have coronas of differing composition growing around them. Both olivine and clinopyroxene are heavily fractured and irregularly shaped.
Plagioclase and clinopyroxene form subhedral, unaltered grains amongst a background of finer-grained, intermingled iddingsite and zeolites. Iddingsite may be a pseudomorph after biotite. Described by Western Minerals Inc. as an 'interstitial ferrotholeiite, very highly fractionatedâ€¦textures are similar to those associated with rapidly frozen or highly viscous melts.'
This vesicular rhyolite has a handful of anhedral quartz phenocrysts. The majority of the sample is sericitized groundmass.
The crystals in this thin section look somewhat out of equilibrium with the melt. The groundmass is microcrystalline and riddled with plagioclase and pyroxenes, as well as glass. Crystals of the phenocryst population are generally subhedral, with rounded corners and irregular twins. The pyroxenes are frequently rimmed by pyroxenes of differing composition. Plagioclase phenocrysts are of differing generations; the first has cloudy, inclusion-rich cores with fresh rims and the second lacks this core. Both may be concentrically zoned. The pyroxenes in particular tend to cluster in glomeroporphyroclasts. The occasional granular aggregate of calcite can be observed in this sample.
The least altered phase in this thin section is plagioclase, which forms roughly aligned, variably sized laths that make up both the groundmass, which is dominantly glass, and the phenocryst population. A second phenocryst, clinopyroxene, remains only as inclusions in the calcite pseudomorphs that replaced it. Vesicles, clays, and hematite pseudomorphs are abundant in this thin section.
The dominant texture in this gabbro is an ophitic intergrowth of equant plagioclase laths within larger, subhedral, clinopyroxene grains. Alteration of some phases to chlorite, talc and iddingsite is localized and occurs more in non-ophitic sections of the rock.
This groundmass heavy thin section is comprised of indistinguishable quartzofeldspathic phases. Round hematite nodules locally stain the groundmass around them. Anhedral phenocrysts of k-feldspar have been almost entirely replaced by sericite.
The foliation in this thin section, defined primarily by aligned glaucophane and clinozoisite, as well as strings of euhedral and aggregated sphene, wraps around larger, equant omphacite and glaucophane grains. The grain size is larger than many others in this suite and the foliation weaker.
Glaucophane, muscovite, sphene, and elongate aggregates of epidote-group minerals define the foliation in this thin section. Poikiloblastic garnet and omphacite grains contain inclusions which include glaucophane and rutile.
This inequigranular mosaic of pyroxenes and olivine is highly fractured. Subparallel swarms of high-density fractures are visible throughout and contain the highest concentrations of serpentine. The infilled minerals of one conspicuous vein have a nice comb texture.
This vesicular basalt contains microphenocrysts of olivine and orthopyroxene, both of which are also lesser components of the groundmass which consists mainly of uniformly-sized plagioclase laths. The olivine phenocryst have weak reaction rims. Some plagioclase is zoned and sieved.
